Embodiment Construction
[0019] During the production process of aliphatic hydroxysulfonate water reducer, the exhaust gas enters the waste gas spray tower 1 from the production waste gas inlet 4, and there is a section of packing layer 5 in the waste gas spray tower 1, and the bottom of the waste gas spray tower stores a solution 7, the solution 7. Driven by the circulation pump 8, it is sprayed out from the spray port 6, and is in gas-liquid contact with the production waste gas in the waste gas spray tower 1 to absorb the production waste gas; The exhaust gas outlet 9 and the exhaust gas outlet 10 in the exhaust gas absorption tank 2 after the leaching tower enter the exhaust gas absorption tank 2, and after being absorbed by the exhaust gas absorption tank 2, they are discharged through the exhaust tube 3 from the gas outlet 11.
[0020] Using the above treatment method, adjusting the concentration of the solution, the height of the packing layer of the spray tower, the spray volume and the liquid ...

The invention provides a treatment method for waste gas from production of an aliphatic hydroxy sulphonate water reducing agent. A waste gas treatment device used for the method includes a waste gas spraying tower, a water gas absorbing tank and an exhausting barrel. The waste gas spraying tower, the water gas absorbing tank and the exhausting barrel are connected through a pipeline. A segment of filler layer is arranged on the waste gas spraying tower. Solutions are contained in the waste gas spraying tower and the water gas absorbing tank. The treatment method includes the steps that production waste gas firstly enters the waste gas spraying tower; after passing the waste gas spraying tower, the production waste gas is introduced into the waste gas absorbing tank; after being absorbed through a liquid seal, the waste gas is conveyed to 15-meter high air to be exhausted through the exhausting barrel. Compared with a traditional water or alkaline water absorbing effect, the absorbing effect of the treatment method is much higher; by combining a spraying tail gas treatment mode with a liquid seal tail gas treatment mode, the waste gas absorbing efficiency is further improved; a sodium metabisulfite solution used for absorbing acetone and formaldehyde can be used as a synthetic raw material of the water reducing agent, and no secondary pollution is caused.
Description
technical field [0001] The invention relates to a method for treating waste gas produced by an aliphatic hydroxysulfonate water reducer. Background technique [0002] Aliphatic hydroxysulfonate superplasticizer is made of acetone, formaldehyde, sulfite, etc. as the main raw materials, and is prepared by sulfonation and condensation under the catalysis of alkaline substances. It has the advantages of high water reducing rate, low price, simple production process, and no air-entrainment. However, because acetone and formaldehyde are extremely volatile substances among its raw materials, a large amount of harmful waste gas will escape the reaction system during the production process, accompanied by stirring and reaction heat release. [0003] To solve this problem, in the aliphatic hydroxysulfonate water reducer production line, an exhaust gas pipe will be set up above the reactor, and the production exhaust gas generated by the reactor will be sent to the exhaust gas treatme...
