The exhaust gas purification process of the stenter machine
1. Water spray treatment and electrostatic treatment are commonly used in the waste gas treatment process of setting machine. The electrostatic treatment process has not been widely accepted by the market because it is difficult to solve the difficulties of exhaust gas filtration and effective prevention of equipment fires, and the cost of construction and operation and maintenance is relatively high.
2. The water spray treatment process is easy to operate and maintain, and the cost of construction and maintenance is low. It can not only effectively control printing and dyeing waste gas, but also recover waste oil to generate economic benefits. At present, the water spray treatment process has been widely promoted and applied in the waste gas treatment project of the printing and dyeing industry.
3. Spray washing treatment process can effectively remove harmful gases such as dissolved organic matter, silicon oil and organic gas.
4. Install a dehydration device to remove the water in the spray washing process.
5. Set up a waste oil recovery device to recover and separate the waste oil in the circulating water tank.
6. Schematic diagram of the process flow: waste gas air duct washing purification tower dehydration device exhaust duct circulating water tank circulating water pump up to standard discharge (oil-water separation) waste oil recovery.
7. The waste gas discharged during production enters the air supply pipe. The waste gas treatment scrubber is introduced from the air supply pipe. The washing effect is carried out, and it is discharged from the exhaust duct after washing.
8. The principle of washing effect is that after the gas enters the tower, it is evenly distributed in the tower, and the water pump sprays the high-pressure water evenly on the effective section of waste gas treatment, so that the liquid and the gas can fully contact. In order to achieve the washing effect.
9. The exhaust gas is after washing. Dehydration is carried out by a dehydrator. Make the purified gas discharge up to standard.
10. After sufficient washing treatment, the odorous gas produced is absorbed by the washing liquid into the circulating water, and the clean, tasteless and odorless gas can be output to the purification device after being dehydrated by the dehydrator, and discharged up to the standard.
11. While the silicone oil is washed by water, organic gases (trichlorobenzene, methylnaphthalene, methyl benzoate, biphenyl) are compatible with water, while silicone oil is only incompatible with water. The phenomenon of water miscibility, so the two can be washed at the same time; at the same time, silicon oil can float in water to facilitate collection and recovery.
The principle of exhaust gas purification of setting machine
The high-temperature exhaust gas generated by the setting machine enters the exhaust gas purifier, and enters the spray area after slow flow, uniform flow, and diffusion in the diversion area. The flue gas is in contact with the turbulent flow of high-pressure water mist in the spray area. , dust, and oil mist are captured by water mist and flow into the oil-water separation tank through the drain outlet at the bottom of the purifier. After spray purification and cooling, the gas enters the dehydration area from the spray area, and the dehydrated clean gas is discharged into the atmosphere from the top of the purifier through the exhaust pipe.
Summary: What do you know about the process and principle of exhaust gas purification of setting machine? After reading this article, you should have a basic understanding and understanding. I believe everyone understands it! In general, I hope it will be helpful to everyone.
