Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device which is convenient for replacing a filter element. Background Art

[0002] Tris(hydroxymethyl)aminomethane, or Tris, is a white crystal or powder, soluble in ethanol and water, slightly soluble in ethyl acetate and benzene, insoluble in ether and carbon tetrachloride, corrosive to copper and aluminum, and an irritating chemical. The production of tris(hydroxymethyl)aminomethane usually involves the hydroxymethylation reaction of nitromethane and the subsequent reduction reaction. During these reactions, some by-products or waste gases may be produced, but the properties of these gases (acidic or alkaline) are not fixed, but depend on the specific conditions of the reaction and the raw materials and catalysts used. Therefore, the waste gas produced needs to be filtered to reduce the harm to the R&D environment.

[0003] In the use of existing exhaust gas treatment devices, a filter screen is usually installed inside the filter tube to allow water to pass through, and filter material is installed on the top of the filter screen to absorb harmful substances in the exhaust gas. However, when dealing with different types of gas properties, the filter tube needs to be disassembled, and the filter material therein needs to be poured out, and then different types of filter materials need to be replaced to facilitate filtering of acidic or alkaline gases. The filter material is easily scattered when being poured out, and is not easy to operate. In addition, there is a lack of a layered isolation device, and only a single type of gas can be filtered. Therefore, an exhaust gas treatment device that is easy to replace the filter element is proposed to solve the above problems. Utility Model Content
