Which measure is more effective for artificial leather exhaust gas control?

Nowadays, the use of artificial leather is very common, because this material is very affordable in comparison. However, the workshop that produces PVC artificial leather will produce waste gas, because the plasticizers used in the production and processing of artificial leather can play a role. Its function is to make the product more elastic or flexible, and it also produces VOC organic waste gas. Because the plasticizer component was not included in the discharged pollutants in the previous emission standards, many PVC manufacturers now produce waste gas The emissions are all unqualified, so in this article, the editor of Foshan Boton Air Company will take you to understand the methods and methods used to treat artificial leather exhaust gas?

We learned that in the production of PVC artificial leather, most of the plasticizers used are DOP plasticizers. This plasticizer is also very toxic and has a serious impact on human health and the environment. Of course, it also DOA plasticizer or DINP plasticizer will be used, but the dosage is relatively small. The temperature of the exhaust gas generated during the production process is about 80 to 95 degrees, and some mist-like exhaust gas will be produced. To deal with the mist Such waste gas and smoke are usually treated with oil fume purifiers. The following are four artificial leather waste gas treatment methods. I hope it will be helpful to you in dealing with waste gas.

1. Electrostatic control method: Use electrostatic filtering cell to remove particulate matter and volatile organic substances in oil smoke. The working process includes gas molecule electricity, oil mist particle charging, and the charged particles move toward the cylinder under the action of the electric field and reach the anode, thereby achieving the purpose of removing particulate matter in the oil fume. The oil fume collection efficiency is high, and the purification efficiency can reach above 95%. We are professional electrostatic precipitator manufacturer in China.

2. Combustion method: Thermal oxidation reaction is used to oxidize the organic matter in the oil fume exhaust gas into stable and harmless substances. According to whether a catalyst is added during the combustion process, it can be divided into direct combustion method and catalytic combustion method. Its purification efficiency can reach more than 90%, but its fuel consumption cost is relatively high, and it is mainly used in flammable aerosol and gas gas compositions.

3. Washing method: Use the contact between liquid and oil fume to remove particulate matter and volatile organic gases. Therefore, there are as many specific technologies as there are gas-liquid contact methods, which indirectly increases the cost of the enterprise and makes the whole process more complicated.

4. Adsorption method: Use adsorbent materials to intercept, collide, and screen oil fumes to remove particulate matter and volatile organic gases. The main key point of this technology is the selection of filter adsorption materials. Different filter adsorption materials have different effects. However, the purification efficiency of this method can usually reach more than 85%, and the operation of the equipment is stable and reliable. However, oil fumes with high humidity will block the adsorption space and reduce the performance and service life of the filter adsorption material.

Above we have introduced four artificial leather exhaust gas treatment methods. The first and fourth methods are more commonly used. No matter which method is used, the equipment still needs to be maintained and cleaned regularly. If consumables need to be replaced, It also needs to be replaced to meet the stable operation of the exhaust gas treatment equipment. If your company encounters problems in exhaust gas treatment, or the exhaust gas treatment equipment installed cannot meet the emission requirements, you are welcome to get in touch with us.
