Problems solved by technology

[0006] The technical problem to be improved by the present invention: it is impossible to flexibly adjust the space size of each sub-spray area according to the sulfur content in the exhaust gas, and then adjust the exhaust gas in different spray areas. The residence time of the desulfurization agent is used to achieve the best spray desulfurization time ratio and desulfurization agent loss ratio, thereby reducing the use of desulfurization agent and the desulfurization efficiency of the desulfurization tower

Abstract

The invention relates to the technical field of chemical engineering, in particular to a partitioned spraying desulfurizing tower and a desulfurizing device.The partitioned spraying desulfurizing tower comprises a tank body, and a first air inlet pipe is fixedly connected to the bottom of the tank body; the first gas inlet pipe is communicated with external flue gas through a gas channel; the layering assembly is positioned in the tank body and is used for layering flue gas entering the tank body; the spraying assembly is positioned in the tank body; the flue gas desulfurization assembly is used for desulfurizing flue gas in each layer after the layering assembly; the gas outlet pipe penetrates through the top of the tank; through cooperation of the spraying assembly and the layering assembly, the volume of the spraying section in the tank body can be flexibly adjusted through movement of the layering assembly, and the problem that the space size of each subarea spraying area cannot be flexibly adjusted according to the content of sulfur in waste gas through fixed subarea spraying is solved; further, the residence time of the flue gas in different spraying areas is adjusted, so that the optimal spraying desulfurization time proportion and the optimal desulfurization agent loss proportion are achieved, and the use effect of the desulfurization agent and the desulfurization efficiency of the desulfurization tower are improved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a zone spray desulfurization tower and a desulfurization device. Background technique [0002] The desulfurization tower is a tower-type equipment for desulfurization treatment of industrial waste gas; the main operation mode of the waste gas purification spray tower is that the acid mist waste gas is introduced into the purification tower through the air duct, and the waste gas and the sodium hydroxide absorption liquid undergo a gas-liquid two-phase process through the packing layer. The phase is fully contacted to absorb and neutralize the reaction. After the acid mist exhaust gas is purified, it is dewatered and demisted by the defogging plate and then discharged into the atmosphere by the fan; [0003] The absorption liquid is pressurized by the water pump at the bottom of the tower and sprayed down at the top of the tower, and finally returned to the bottom of the...
