Vocs equipment industry heat exchanger type description

Every accessory in the vocs device has its function, so every accessory in the vocs device can't be less. So what is the heat exchanger in the Wuxi LNEYA vocs device? What are the main types?

Tank heat exchanger: Compared with the traditional heat exchanger, the tank heat exchanger has high heat exchange efficiency, small volume, convenient water circulation, water inlet at the bottom of the waterway, easy drainage, and can effectively reduce dirt. Moreover, the tank heat exchanger can be used as an evaporator and a condenser, or can be connected and piped in parallel or in series to meet the requirements of a large system.

Plate heat exchanger: Since the plate heat exchanger adopts the method of fluid heat dissipation, the heat dissipation efficiency is very high, which can reach 95%. In the two industries, the heat exchange efficiency can reach such a high number of products.

Casing heat exchanger: Although the heat dissipation efficiency of the tube-type heat exchanger can only reach about 75% relative to the plate heat exchanger, it is easy to freeze and block compared to the tube heat exchanger, and the sleeve type is changed. The heat exchanger does not have this problem.

Evaporative condenser: Unlike other two products, evaporative condenser is neither an air-cooled heat exchanger nor a water-cooled heat exchanger. It combines the advantages of air cooling and water cooling to form its own powerful heat dissipation. effectiveness.

Shell-and-tube heat exchanger: As a veteran product in water-cooled heat exchangers, shell-and-tube heat exchangers are mainly used in large equipment such as refrigeration and refrigeration. This is due to the fact that once the failure of the shell-and-tube heat exchanger affects the entire system, it will inevitably cause great losses. Therefore, the shell-and-tube heat exchanger is highly demanding in terms of quality.

Finned heat exchangers: The chip heat exchangers have been developed for a long time in the refrigeration equipment industry and have a wide range of applications. Because fin-type heat exchangers are prone to irreversible damage to products due to external forces during long-distance transportation, the requirements for transportation and logistics of their products are relatively high. In order to reduce costs, finned heat exchangers are produced. It is spread all over the country to facilitate the development of the refrigeration industry.

Regardless of the type of heat exchanger, LNEYA vocs equipment selects the heat exchanger of the brand manufacturer when selecting the type of heat exchanger to ensure efficient operation of the vocs equipment.

How to deal with organic waste gas treatment refrigerant leakage?

In the process of organic waste gas treatment, if it is found that the refrigerant leaks, it is recommended to treat it in time. LNEYA organic waste gas treatment professional manufacturer then analyzes the knowledge of organic waste gas treatment refrigerant leakage.

Organic waste gas treatment VOCS gas single material or multi-material condensation recovery, the main treatment gases are: hydrocarbons such as gasoline, crude oil, fuel oil, kerosene, diesel, heavy oil, mixed hydrocarbons; aromatics: benzene, toluene, xylene, Styrene, naphtha, etc.; alcohols, ethers, ketones, esters, etc., in the event of a situation, we must now fill the leak or treatment of the refrigerant leakage, then replace the desiccant, re-vacuum treatment, Fill the appropriate refrigerant. When you find that the leaking refrigerant is partially immersed in water, stop the chiller and quickly remove the water from the tank to prevent the compressor from drawing water into the system for more serious damage.

So, what should be done if the organic waste gas treatment refrigerant is found to be insufficient? Organic waste gas treatment failure phenomenon: the whole vehicle refrigeration effect is poor, the air outlet air is only cool, and the manifold pressure gauge check finds that the high pressure is cut and the low pressure side pressure is low (when the compressor speed is 2000/mim, the ambient temperature is about 35C). The low pressure gauge index is lower than 1kg/CM square, the high pressure gauge index is lower than 10kg/CM square, and the bubble flow is visible from the sight glass.

This may be due to a refrigerant leak point in the refrigeration system, resulting in insufficient refrigerant. Treatment method Use an electronic leak detector to detect the leak point and carry out the replacement or replacement of parts. If the parts are not replaced, only the appropriate amount of refrigerant can be replenished; if the parts are replaced, the appropriate amount of refrigerating oil should be added as required, and the refrigerant should be added after the system is vacuumed.

The above is the relevant treatment of organic waste gas treatment refrigerant leakage. If the Wuxi LNEYA organic waste gas treatment equipment fails, it is recommended to solve it in time!

Organic waste gas treatment device noise description

With the increasingly stringent environmental requirements, various manufacturers have paid more and more attention to their own organic waste gas treatment. LNEYA organic waste gas treatment equipment specializes in the treatment of various organic waste gases and promotes continuous optimization of environmental protection issues.

In the internal structure of the organic waste gas treatment device, the compressor is the core position. Generally, the compressor has two types of compressors, a scroll type and a screw type. This depends on your needs to select a suitable compressor once the compressor If there is noise, you should first check if the expansion valve is over-opened. If you open it, you should turn it down. Next, check if the refrigerant is too much. If it exceeds the limit, remember to eliminate the excess chiller.
If the organic waste gas treatment device emits noise, the water quality is basically problematic. The organic waste gas treatment device recommends that you perform water treatment according to the corresponding requirements.

Most of the organic waste gas treatment devices are made of metal. Once your parts lack lubrication, they will generate a certain amount of friction and make noise. In addition to this, everyone should pay attention to maintenance, so that there will be fewer failures. point.

If there is noise in the organic waste gas treatment device, you can check whether the compressor is short of oil. If it is out of oil, check it up quickly, check the load of the compressor in time, and solve the problem in time.

The above knowledge of organic waste gas treatment equipment can also help you effectively solve some of the problems of use. At the same time, you can pay attention to LNEYA Constant Temperature Refrigeration Technology Co., Ltd., and introduce new products every year according to industry trends, so stay tuned.

Organic waste gas recovery unit refrigeration oil requirements description

The organic waste gas recovery device is slightly different for different gases. The LNEYA organic waste gas recovery device and the vocs gas condensation recovery device are operated by the principles of condensation and adsorption. The refrigeration oil is also important, then the refrigeration oil has What is the requirement?

The cloud point of the frozen oil of the organic waste gas recovery device refers to the temperature at which the paraffin is precipitated in the frozen oil and the lubricating oil becomes turbid when the temperature is lowered to a certain value. The cloud point of the refrigeration oil used in the device should be lower than the evaporation temperature of the refrigerant, otherwise it will cause the throttle valve to block or affect the heat transfer performance.

The temperature at which the frozen oil is cooled under experimental conditions to stop flowing is referred to as the freezing point. The freezing point of the frozen oil used in the organic waste gas recovery device should be as low as possible (such as R22 compressor, the refrigeration oil should be below -55 °C), otherwise it will affect the flow of the refrigerant and increase the flow resistance, resulting in poor heat transfer. as a result of.

An important parameter in the characteristics of the oil viscosity of the refrigerating oil. Different refrigerants should be used to select different refrigerating oils. If the viscosity of the frozen oil is too large, the mechanical friction power, friction heat and starting torque will increase. On the other hand, if the viscosity is too small, the desired oil film cannot be formed between the moving parts, so that the desired lubrication and cooling effect cannot be achieved.

The flash point of a frozen oil is the temperature at which the lubricating oil is heated to the point where it is ignited when it comes into contact with the flame. The flash point of the frozen oil used in the organic waste gas recovery device must be 15 to 30 ° C higher than the exhaust gas temperature to avoid burning and coking of the lubricating oil. Organic waste gas recovery devices such as chemical stability and oxidation resistance, moisture and mechanical impurities, and insulation properties.

As far as the current environmental protection trend is concerned, if the company has organic waste gas, it is recommended to buy an organic waste gas recovery device for gas treatment as soon as possible to avoid troubles.

Vocs gas condensation recovery unit processing instructions

With the continuous inspection of environmental protection, Wuxi LNEYA VOCS gas condensation recovery device has also received continuous attention from the public. Most chemical, pharmaceutical and industrial industries are urgently dealing with vocs gas.

The so-called VOCS is a volatile organic compound, and its composition generally includes an alkane, an olefin, an aromatic hydrocarbon, a halogenated hydrocarbon, an oxygenated hydrocarbon, a nitrogen hydrocarbon, a sulfur hydrocarbon, a low boiling polycyclic aromatic hydrocarbon, and the like. At present, most of the vocs gas is caused by industrial pollution, so the Wuxi Guanya vocs gas condensation recovery device is applied to the respiratory volatilization loss of the emptying valve in the storage tank area; the stochastic volatilization loss of the tank truck in the loading and unloading area; The solvent evaporation loss of the stirred reaction kettle; the various volatile chemicals loading, chemical storage and transportation, and the recovery of various volatile VOCS gases generated by the chemical pharmaceutical industry.

Wuxi LNEYA's vocs gas condensation recovery unit is used for VOCS gas single material or multi-material condensation recovery. For hydrocarbon gases such as gasoline, crude oil, fuel oil, kerosene, diesel oil, heavy oil, mixed hydrocarbons, aromatic gases such as benzene, toluene, and Toluene, styrene, naphtha, etc., alcohols, ethers, ketones, esters, etc., vocs gas condensation recovery device will introduce volatile VOCS gas into the equipment cold box (the device is more condensing temperature set 3 ° C -40 ° C -75 ° C -115 ° C) can be customized for other temperature zones, follow-up requirements for condensing liquefaction. Part of the continuous production process has done a two-way switching process in the low temperature section (after one side of the ice block, it is directly switched to another heat exchange cold box condensation, while the ice block side is treated with defrost). For the recovery of solvent gas, it can meet the environmental emission standards of exhaust gas according to the demand; if the gas has low boiling point gas, it can be separated and treated again by activated carbon adsorption, membrane treatment and other processes to make the emission gas meet environmental protection requirements.

In fact, vocs gas has a relatively large impact on our lives. In winter, due to various air pollution, our life and environment can not be underestimated. Generally, it can be treated by adsorption and condensation. Adsorption can be carried out by sorbent and VOCS. Physical or chemical reaction removal, suitable for the removal of low and medium concentrations of VOCS contaminants, this method is relatively efficient and easy to control, but not suitable for high concentration of pollutants.

LNEYA cooling and heating thermostat bath instructions

Circulating thermostatic water bath is water circulation and cooling function based on the increase in the water bath, can improve the precision of temperature control and temperature stability, can be widely used for drying, distillation, concentration, dipping in chemical reagents, impregnation of pharmaceutical and biological products, can also be used for constant heating water and other temperature test, is a biological, genetic, viral, aquaculture, environmental protection, medicine, health, biochemical laboratory, analysis room, education and scientific research necessary tools.

As we all know, there are very few impurities in the water, so does distilled water after adding to the tank.

For heating and cooling thermostatic baths, the general temperature is set at 20 ℃, specially adapted to the growth and reproduction of microorganisms. After a long time, these microorganisms will clog the waterway filter, lead to backwater, then the pump will have large noise.

Sometimes these microorganisms are attached to the surface of the heat exchanger, reducing the effectiveness of heat transfer, and making the refrigeration quantity smaller.

Therefore, the routine maintenance must be strictly executed in accordance with the requirements of the manual. Clean the inner grooves regularly and keep dry during long-term shut-down.

When Heating and cooling Thermostatic Bath seems to be a leak, sometimes the ground for a few drops, check if there is a leakage on the waterway? Generally, it will not leak during abnormal usage. When the ambient temperature is relatively high in the air together with large humidity, the moisture on the pump, water pipe joints, external water pipes of the waterway in the water circulation are easily condensed out as dew, then accumulated and dropped to the ground, so do not worry whether there is somewhere leak. If you care about it, turning on the air-conditioning to reduce room temperature or dehumidifying can prevent the dew.
