They can be used to remove organic matter from waste gas and wastewater, decolorize sugar solutions, and separate and purify natural products and biochemical products.
[0003] The waste gas generated during industrial production processes is characterized by high temperature and high humidity. High temperature and high humidity environments are not conducive to resin adsorption. Existing VOCs acidic waste gas resin adsorption treatment devices cannot perform pretreatment measures to regulate the temperature and humidity of the waste gas, resulting in poor resin adsorption capacity and low waste gas treatment efficiency and poor effect.

This increases the amount of raw materials and time required for exhaust gas treatment, resulting in a waste of time and resources. Utility Model Content

[0025] The cooling and dehumidification module 2 includes a housing 21 and a water inlet pipe 22. The water inlet pipe 22 is fixedly installed on the outside of the housing 21.
