Description

A waste gas treatment device for high-performance water reducer production equipment

Technical field:

The invention relates to a waste gas treatment device of high-performance water reducing agent production equipment, belonging to the technical field of water reducing agent production equipment.

Background technique:

Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete. Most of them are anionic surfactants, such as lignosulfonate, naphthalenesulfonate formaldehyde polymer, etc. After being added to the concrete mixture, it can disperse the cement particles, improve its workability, reduce the unit water consumption, improve the fluidity of the concrete mixture; or reduce the unit cement consumption and save cement.

At present, the production process of water reducing agent basically adopts the process of open equipment system, and the formaldehyde is emptied directly to the atmosphere, which not only wastes raw formaldehyde, pollutes the environment, and endangers the health of employees, but also reduces production efficiency and product quality. The quality stability of the water reducing agent is not ideal. During the synthesis process of the water reducing agent, some acids need to be added for reaction, such as acrylic acid, methacrylic acid, thioglycolic acid, etc. These acids are volatile substances, which must be recovered and cannot be directly Emissions are likely to cause pollution to the environment.

Invention content:

In view of the above problems, the technical problem to be solved by the present invention is to provide an exhaust gas treatment device for high-performance water reducer production equipment.

The waste gas treatment device of a high-performance water reducer production equipment of the present invention comprises a tank body, a spray device, a motor, a valve, a reaction tank, an air inlet, a lye tank, a liquid suction pump, a PH detector, a first Pipeline, electric fan, second pipeline, blending kettle, finished product storage tank, third pipeline, spraying device is installed on the upper part of the tank body, the spraying device is connected to the motor, and a valve is set between the spraying device and the motor, the bottom of the tank body There is a reaction pool, one end of the reaction pool is provided with an air inlet, the air inlet is connected to the exhaust port of the reaction kettle, the other end of the reaction pool is connected to the lye pool, and a suction pump is set between the reaction pool and the lye pool , the tank is equipped with a PH detector, the top of the tank is connected to the electric fan through the first pipeline, the bottom material output end of the tank is connected to the material input end of the blending kettle through the second pipeline, and the inlet end of the finished product storage tank is connected through the second pipeline. The three pipelines are connected with the material output end of the blending kettle.

As a preference, an emptying valve is arranged on the top of the tank to drain the liquid in the reaction pool.

Preferably, the first pipeline is an air suction pipeline, and an air suction valve is arranged in the air suction pipeline, which can not only control the gas flow during the reaction process, but also discharge the liquid in the reaction tank. The valve can prevent the liquid from being sucked back into the suction pipe and play a role in preventing the liquid from flowing back.

Beneficial effects of the present invention: it has reasonable structural design, simple operation, and convenient use. It can not only effectively deal with a large amount of waste gas discharged in the production of water reducing agents, but also truly achieve zero pollution, low material consumption, and no waste gas in water reducing agent products. Formaldehyde residues, the stability of the product during storage, improve the quality of the product, save the operating cost of the enterprise, and are environmentally friendly and practical.
