[0002] Waste gas is generated during the calcination of alkali slag.

[0029] A purification process for waste gas generated by calcining alkali slag, using the above-mentioned purification device for waste gas generated by calcining alkali slag, comprises the following steps:

[0030] S1: The waste gas generated by calcining alkali slag is transported to the treatment cylinder through an air pump, an air pipe, and an air pipe. At this time, the waste gas passes through multiple purification net cylinders in sequence, and then flows from the gap between the partition plate and the treatment box to the top of the partition plate, and then flows to the top of the treatment cylinder through the air outlet pipe;

[0031] S2: Water from the outside is sprayed into the treatment box through the spray pipe to spray the gas flowing out of the gas outlet pipe. The sprayed water is intercepted and collected above the sealing strip under the action of the sealing strip. The sprayed gas flows into the lower position of the treatment cylinder through the gas pipe 2;

[0034] S5: Turn on the motor, the motor drives the gear ring to rotate through gear 2, the gear ring rotates to drive the dust bag assembly fixedly connected to it to rotate, and the dust bag assembly rotates to drive the other dust bag assemblies to rotate through transmission structure 3;

[0035] S6: The gas treated by the dust bag assembly flows out of the treatment box through pipe body three.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] 1: The larger dispersed particles in the exhaust gas are first preliminarily filtered through the purification net cylinder, and then the preliminarily filtered exhaust gas is sprayed, and the flow speed and angle of the exhaust gas are intermittently controlled during the spraying process, which can effectively promote the spray purification effect; finally, the exhaust gas is further processed by the rotatable dust bag assembly, and the dust bag assembly rotates while filtering. The rotation can be used to remove water stains adhering to the dust bag assembly on the one hand, and on the other hand, it can directly promote the purification effect of the dust bag assembly.

[0038] 2: The reciprocating speed-controlled shutter can be used to control the flow rate when the airflow passes through the outlet pipe. At the same time, during the movement of the speed-controlled shutter, the outlet pipe can be driven to swing back and forth intermittently with a certain amplitude through the cooperation of the swinging part, which can effectively improve the contact effect between gas and water, and improve the spray purification effect of exhaust gas.

[0039] 3: Use a screw that can rotate regularly to control the purification net cylinder to swing back and forth at a certain angle, effectively scrape off the larger particles intercepted on its surface, and ensure the purification effect of the purification net cylinder.
