Activated carbon adsorption and desorption equipment is a kind of equipment widely used in environmental protection, chemical industry, medicine, food and other fields. It mainly uses the adsorption characteristics of activated carbon to separate and purify various gases and liquids. This article will comprehensively analyze the principle and application of activated carbon adsorption and desorption…
Bag filter is a dry dust filter. After the filter material is used for a period of time, due to the effects of screening, collision, retention, diffusion, static electricity, etc., a layer of dust accumulates on the surface of the filter bag. This layer of dust is called the primary layer. In the subsequent movement…
The biofilter deodorization equipment is an environmental protection device based on microbial metabolism, and its core consists of a pretreatment unit and a biofilter bed. The pretreatment unit removes large particle pollutants and adjusts the temperature and humidity of the gas through spraying, dust removal, humidification and other steps; the biofilter bed is filled with…
