Description

A kind of chemical flue gas dust removal

Technical Field

The utility model relates to the technical field of flue gas dust removal, in particular to a flue gas dust removal for chemical industry.

Background Art

Chemical companies generate a large amount of flue gas during the production process. At present, in order to protect the environment, companies are required to treat the exhaust gas before discharging it. The purpose of exhaust gas treatment by chemical companies is to reduce the impact of exhaust gas on the environment and human health. Through scientific emission control and treatment technology, the content of harmful substances in exhaust gas can be effectively reduced, reducing pollution to the atmosphere.

The current method of treating flue gas is to first remove dust from the flue gas, then treat some harmful components in the flue gas one by one, and then discharge the harmless gas into the atmosphere. As for the method of removing dust from the flue gas, the current common method is to use activated carbon for adsorption. The smoke dust particles are adsorbed on the activated carbon through activated carbon adsorption to remove the smoke dust.

Although the above method of removing smoke dust can be realized, the amount of smoke is large, and only adsorption by activated carbon will quickly block the gaps in the activated carbon, resulting in the inability to adsorb the subsequent smoke, thereby affecting the dust removal effect. Therefore, we propose a chemical flue gas dust removal to solve the above problem.

Specifically, the working process or working principle of a flue gas dust removal for chemical industry is as follows: the current method of treating flue gas is to first remove the dust from the flue gas, and then treat some harmful components in the flue gas one by one, and then discharge the harmless gas into the atmosphere. Regarding the method of removing the dust from the flue gas, the current common method is to use activated carbon for adsorption, and the smoke dust particles are adsorbed on the activated carbon through activated carbon adsorption, so as to remove the smoke dust.

Although the above-mentioned method of removing smoke dust can be realized, the amount of smoke is large, and only adsorption by activated carbon will quickly block the gaps in the activated carbon, resulting in the inability to adsorb the subsequent smoke, thereby affecting the dust removal effect. Therefore, this device is designed to connect an external power supply, and transport the external smoke to the inside of the air intake pipe 1 through the circular tube 4, and transport the gas inside the air intake pipe 1 to the inside of the processing box 31. At the same time, the condenser 32 and the pump 8 are turned on.

To ensure that the processing box 31 can be used continuously, turn on the drive motor 131 and the dust collector 18, the drive motor 131 drives the main gear 15 to rotate, and drives the sub-gear 16 to rotate, moves and drives the hollow cylinder 17 to rotate, and drives the grinding plate 134 to rotate. The crystals are ground by the grinding plate 134 to be ground into tiny particles. The crystals in this state will fall to the bottom of the processing box 31. At the same time, under the continuous suction of the dust suction pipe 133, the crystals in this state are sucked into the inside of the dust suction pipe 133 and transported to the inside of the dust collecting bin 20. The crystals are cleaned out from the inside of the processing box 31, so that the device can be used continuously to remove dust from the flue gas.

It should be noted that the condenser 32, the liquid pump 8, the drive motor 131 and the impurity suction machine 18 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
