Problems solved by technology

[0002] During the production process of biguanides, chemical reactions will produce a large amount of harmful gases. If these gases are directly discharged into the air, they will cause serious pollution to the environment and air quality. The existing way of treating waste gas is to use high-altitude emissions. The treatment method cannot fundamentally eliminate the air pollution caused by the emission of exhaust gas

Abstract

The invention relates to a biguanide type waste gas treatment system. The biguanide type waste gas treatment system is used for performing physical and chemical reaction and treatment on biguanide type industrial waste gas, such as absorbing and adsorbing, so as to realize the zero-waste gas emission and zero-pollution to environment and air. The biguanide type waste gas treatment system belongs to the field of equipment of biguanide type production, and particularly relates to the field of waste gas treatment in chemical production. The biguanide type waste gas treatment system comprises a primary water scrubber, an alkaline scrubber, a secondary water scrubber, a filter, a fan, an adsorbing tank A, an adsorbing tank B, a condenser, and a solvent delaminating tank. The biguanide type waste gas treatment system has the advantages that the dimethylformamide and hydrogen chloride gases in the waste gas can be removed, and the methylbenzene in the waste gas can be recycled; the environment-friendly requirement is met, and the economic benefit can be produced.

Description

technical field [0001] The invention relates to a biguanide industrial tail gas treatment device. Background technique [0002] During the production process of biguanides, chemical reactions will produce a large amount of harmful gases. If these gases are directly discharged into the air, they will cause serious pollution to the environment and air quality. The existing way of treating waste gas is to use high-altitude emissions. The treatment method cannot fundamentally eliminate the air pollution caused by the emission of exhaust gas. Contents of the invention [0003] The technical problem solved by the invention is to provide a biguanide waste gas treatment device and a waste gas recovery device with zero waste gas discharge. [0004] In order to solve the above technical problems, the present invention provides a biguanide waste gas treatment system. The waste gas treatment system sequentially includes a primary water washing tower, an alkali washing tower, a second...
