[0002] Waste gas treatment, also known as waste gas purification, primarily refers to the management of industrial waste gases such as dust particles, flue gas, odorous gases, and toxic and hazardous gases generated in industrial sites. Common waste gas treatments include factory smoke waste gas treatment, workshop dust waste gas treatment, organic waste gas treatment, waste gas odor purification, acid and alkali waste gas treatment, and chemical waste gas treatment.

[0003] Among them, acid-base waste gas treatment is generally first carried out through acid-base washing and neutralization, and then through drying and activated carbon adsorption to complete the waste gas treatment. However, the above-mentioned equipment is generally divided into three separate equipment: acid-base neutralization equipment, drying equipment and activated carbon adsorption equipment.

[0027] Installation method and operating principle: Weld the longitudinal partition 3, the first left transverse partition 4, the first right transverse partition 5, the second left transverse partition 6, and the second right transverse partition 7 to the corresponding positions inside the silo body 1, so that the left longitudinal cavity 12 and the right longitudinal cavity 13 are formed inside the silo body 1. The neutralization channel 14 and the air outlet channel 15 are formed in the right longitudinal cavity 13 through the first left transverse partition 4, the first right transverse partition 5, the second left transverse partition 6, and the second right transverse partition 7. Then, connect the top of the intake pipe 9 to the air inlet 18 through a bend, and the bottom of the intake pipe 9 passes through the longitudinal partition 3 through a bend and enters the right longitudinal cavity 13. Then connect the intermediate pipe 1001 of the air distribution pipeline 10 to the bend at the bottom end of the intake pipe 9.

The acidic waste gas enters the bottom of the bin body 1 through the air inlet 18, the air inlet pipe 9 and the air distribution pipeline 10, and comes into contact with the alkaline solution. It then floats up and passes through the neutralization channel 14 formed by the first left transverse partition 4 and the first right transverse partition 5, continuously coming into contact with the alkaline solution, and then enters the air passage 15 formed by the second left transverse partition 6 and the second right transverse partition 7. During the process, it passes through the air holes 16 on both sides of the corresponding loading and air-venting drawer 8, and comes into contact with the desiccant and activated carbon for drying and adsorption treatment. Finally, the treated waste gas is discharged from the air outlet 21 (if alkaline waste gas is treated, acidic solution is used for neutralization). The utility model has a reasonable structure. The interior of the warehouse body 1 is divided into a left longitudinal cavity 12 and a right longitudinal cavity 13 by the longitudinal partition 3. The right longitudinal cavity 13 is respectively formed with the first left transverse partition 4, the first right transverse partition 5 and the second left transverse partition 6, and the second right transverse partition 7 to form a neutralization channel 14 and an air outlet channel 15.
