How to prevent fire and explosion of VOC waste gas treatment equipment?

Today, the editor has sorted out 4 common questions about why VOC waste gas treatment equipment catches fire and avoids equipment fire and explosion. Interested friends, take the time to find out.

1. The concentration value of the exhaust gas in the VOC waste gas solution equipment ensures the lower limit of the concentration value of the explosion accident, which will lead to an explosion accident and a fire. 2. When the concentration value of the explosion accident is guaranteed to be low, sparks are generated nearby and the exhaust gas is encountered. cause fire. 3. The temperature of a certain part of the VOC exhaust gas solution is too high to ensure the flammable point, resulting in sparks and fire. 

So how to deal with it? 1. The equipment should be set in a low temperature area. 2. Do not work with fire near the pipeline. 3. Strictly control the content of VOC exhaust gas. 4. Take safety and fire prevention measures near the equipment.

3. Catalytic reaction rate processing process of catalytic combustion equipment: 1. The key process of the gas entering the catalytic combustion equipment is to be solved, to remove dust, liquid and harmful components, to avoid the blockage of the catalytic reaction rate material layer and the poisoning of metal sulfides .

2. The temperature of the vapor entering the catalytic reaction rate material layer should ensure the ignition temperature of common metal sulfides as much as possible, so that the catalytic reaction rate can be carried out. Therefore, for the exhaust gas below the light-off temperature, try to preheat to ensure the light-off temperature. The manufacturer of VOC exhaust gas solution recommends everyone, especially when driving, to preheat the cold exhaust gas as much as possible. Therefore, the catalytic combustion method is most suitable for cleaning the exhaust pipe. After the air inlet is preheated while driving, the pilot exhaust gas can be used. The calorific value preheats the inlet gas. If the exhaust gas is discharged intermittently, the imported air conditioner needs to be preheated every time you drive, and the frequent operation of the preheater will greatly increase the energy consumption. The preheating method of the vapor can use an electric heating device, and can also use the kitchen flue gas to heat up. At present, the electric heating device is widely used. Exhaust gas treatment equipment, purification tower, catalytic combustion equipment, UV photo-oxygen catalytic equipment.

3. Catalytic combustion reflects the release of many chemical equilibrium constants, and the temperature of the ignition exhaust gas is very high, so try to make comprehensive use of this part of the calorific value. Generally, a heat exchanger is used to exchange the calorific value of the high-temperature exhaust gas with the imported low-temperature gas to reduce the energy consumption of preheating. The remaining calorific value can be comprehensively utilized in other ways. The analytical chemical waste gas discharged from the production and processing equipment has a high temperature. , such as silk covered wire, cable sheath raw materials, etc., the drying treatment temperature can reach more than 300 degrees, and the preheater and heat exchanger can not be set high, but the calorific value of the ignition exhaust gas should still be comprehensively utilized.
