Abstract

The invention discloses a biological purification system for waste gas. The biological purification system comprises a tower body, a top cover connected to the tower body and a circulating liquid pool arranged on one side of the tower body, wherein the top cover is provided with a discharge pipe, the tower body is sequentially provided with a liquid return layer, a gas inlet layer, a pretreatment layer, a purification layer and a filter layer from bottom to top, the tower body is provided with a flow guide sleeve between the pretreatment layer and the purification layer, the diameter of the flow guide sleeve is gradually reduced from bottom to top, and the purification layer is provided with a fixing sleeve, a filler sleeve, a filler frame, a filler tray, a first spraying assembly and a second spraying assembly. The biological purification system for waste gas is reasonable in structural design and convenient to disassemble and assemble, the pretreatment layer and the purification layer can achieve repeated absorption of waste gas and circulating spraying liquid in the filler, and the waste gas treatment efficiency of the filler can be improved.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a waste gas biological purification system. Background technique [0002] Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life; especially in chemical plants, steel plants, pharmaceutical factories, coking plants and oil refineries, etc., the exhaust gas emitted has a strong smell, which seriously pollutes the environment and affects human health. [0003] At present, physical and chemical methods are generally used for waste gas treatment. When treating waste gas, high temperature is required, and expensive oxidants and adsorbents are added, so it has disadvantages such as large investment, high operating cost, strong corrosion and secondary pollution. [0004] Compared with physical and chemical technologies, biological deodorization methods have the advantages of low investment, simple equipment, low equipment and ...
