Waste gas purification treatment system for chloroacetone production

By designing a chloroacetone production waste gas purification and treatment system, the adsorption medium in the adsorption tower is used to adsorb chloroacetone, and steam desorption and cooling water are used to regenerate the waste gas. This solves the problem of direct waste gas pollution in the chloroacetone production process, and realizes the continuous purification of waste gas and the regeneration of the medium.

AI Technical Summary

Technical Problem

The non-condensable gas generated during the production of chloroacetone is directly discharged and causes environmental pollution, and needs to be purified before it can be discharged in compliance with emission standards.

Method used

A waste gas purification and treatment system for chloroacetone production was designed. The adsorption medium in the adsorption tower was used to adsorb chloroacetone. The adsorption medium was regenerated by switching the adsorption tower and steam desorption to achieve continuous purification of the waste gas. This included a combination of steam heating desorption, compressed air cooling, and cooling water circulation cooling.

Benefits of technology

Continuous and uninterrupted purification of exhaust gas is achieved, and the adsorption medium can be regenerated and reused, reducing costs and production downtime.

Abstract

The utility model discloses a waste gas purification treatment system for chloroacetone production, which belongs to the field of waste gas treatment and comprises a waste gas header pipe, a waste gas branch pipe, at least two adsorption towers, a steam inlet pipe, a compressed air inlet pipe and a cooling water tank. The steam inlet pipe is used for feeding hot steam into the adsorption tower, the compressed air inlet pipe is used for feeding compressed air into the adsorption tower to cool an adsorption medium, the cooling water tank is connected with a cooling water inlet of the adsorption tower through a cooling water inlet pipe, and the adsorption tower is further connected with the cooling water tank through a cooling water outlet pipe. The waste gas purification treatment system disclosed by the utility model not only can adsorb chloroacetone in waste gas, so that the waste gas reaches the standard and is discharged after being purified, but also can be switched to another adsorption tower for adsorption and purification after one adsorption tower is saturated in adsorption, so that the continuous purification treatment of the waste gas is realized; the adsorption medium in the adsorption tower can be subjected to thermal desorption regeneration and does not need to be replaced, so that the cost is saved.
