Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for epoxy resin production. Background Art

[0002] The main pollutants of waste gas in the epoxy resin industry include epichlorohydrin (ECH) and other additives. Traditional waste gas treatment processes usually use activated carbon and RTO processes. However, these treatment processes have obvious problems in treating ECH, which is mainly reflected in the fact that the waste gas treatment effect does not meet the standards. Ordinary activated carbon has poor adsorption capacity for ECH, which makes it easy for waste gas to escape and difficult to meet emission standards. For example, a waste gas treatment device (CN219111217U) patented in China, when its rotating shaft rotates, it will drive the blades to rotate. The rotation of the blades will cause the activated carbon particles to be stirred in the purification chamber, so that the activated carbon particles can be in a state of motion, thereby avoiding the situation of local activated carbon saturation failure, and ensuring the adsorption and purification quality of the waste gas. However, its harmful gases are directly discharged to the top of the treatment box after being washed with water in the water tank and absorbed by the activated carbon particles. At this time, the red in the gas contains more water, which will affect the absorption efficiency of the activated carbon particles, and it is not easy to replace after being wet.
