The invention relates to an acid-alkali exhaust-gas treatment system. The system comprises an air inlet pipe (3), a primary treating column (5), a secondary treating column (7), a blower fan (9) and an exhaust pipe (10). An outlet of the air inlet pipe (3) is communicated with the lower part of the primary treating column (5); the top of the primary treating column (5) is communicated with the lower part of the secondary treating column (7); a primary reaction zone (11) is arranged inside the primary treating column (5); multiple secondary reaction zones (12) are disposed inside the secondary treating column (5); the top of the secondary treating column (7) is connected with an air outlet pipe (8), an outlet of which is connected with an inlet of the blower fan (9); an outlet of the blower fan (9) is connected with the exhaust pipe (10); and a pH-value automatic detection device (4) is arranged on a pipeline of the air inlet pipe (3), an intermediate pipe (6) and the exhaust pipe (10). The system has advantages as follows: by the design of multistage filling layers, treating efficiency is high; and as the pH-value automatic detection device cooperates with a chemicals dosing plant, operations are simple.
Description
technical field [0001] The invention relates to a waste gas treatment device, in particular to an acid-base waste gas treatment system. Background technique [0002] With the increasingly serious pollution of volatile organic gases produced in industrial production, this technology is gradually applied to the field of industrial waste gas purification. In order to effectively protect the environment and protect the health of the public, companies with serious industrial waste gas emissions follow the concept of environmental protection. The country's environmental protection law also stipulates this point. For enterprises with serious industrial waste gas emissions, they must be strictly improved, and all things related to industrial waste gas treatment should be fully done. For enterprises dealing with industrial waste gas, the use of industrial waste gas treatment equipment is also very necessary. Not only to solve the problem of pollution, but also to make a certain con...
