Desulfurization tower for preventing spray hole blockage

Abstract

The invention discloses a desulfurization tower for preventing spray hole blockage. The desulfurization tower comprises a support frame and a tower body fixed to the upper end of the support frame, wherein a smoke gas inlet, a smoke gas outlet and a suction fog inlet are respectively formed in the left end, the top end and the right end of the tower body; a step motor is arranged inside the left end of the tower body; a desulfurization cavity is arranged inside the tower body; a spraying mechanism connected with an output shaft of the step motor is arranged in the desulfurization cavity; the spraying mechanism is matched with the absorption fog inlet; a second driving gear is connected onto the output shaft of the step motor through keys; the upper end of the second driving gear is engagedwith a second driven gear; a guide rail fixed onto the left and right ends of the desulfurization cavity is horizontally arranged above the second driven gear. The desulfurization tower has the advantages that a fog pipe can do autoroatation and can also do revolution around the rotating shaft, so that the scattering range of the sprayed absorption fog is expanded and is uniform; the reaction with the smoke gas is sufficient; bristles on a square screw nut is used for performing synchronous cleaning and brushing on a spray hole.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a desulfurization tower for preventing blockage of spray holes. Background technique [0002] With the continuous development of social industry, the degree of industrialization is getting higher and higher, and the scale of production is expanding, and more and more flue gas is discharged into the atmosphere. Among the various gaseous pollutants that affect air quality, the amount of SO2 flue gas The largest and most influential, it causes acid rain, destroys the ecological environment, and affects people's health. Therefore, before these industrial flue gases are discharged into the atmosphere, they all need to be desulfurized through a desulfurization tower. [0003] However, the spraying device in the desulfurization tower needs a high-pressure pump to spray out the desulfurization absorption mist. The nozzle hole of the spraying device is relatively easy to block, an...

Problems solved by technology

[0003] However, the spraying device in the desulfurization tower needs a high-pressure pump to spray out the desulfurization absorption mist. The nozzle hole of the spraying device is relatively easy to block, and because the sprayed absorption mist is directed and does not have many opportunities to contact with the flue gas, so the flue gas The desulfurization efficiency is not high, and the desulfurization effect is not good;
