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

[0034] S5: Turn on the motor. The motor drives the gear ring to rotate through gear two. The rotation of the gear ring drives the dust collector bag assembly fixedly connected to it to rotate.

[0036] Compared with existing technologies, the advantages of this invention are:

[0037] 1. The purification screen first filters larger dispersed particles in the exhaust gas, and then sprays the pre-filtered exhaust gas. During the spraying process, the flow speed and angle of the exhaust gas are intermittently controlled, which can effectively promote the spraying purification effect. Finally, the rotatable dust collector bag assembly is used to further treat the exhaust gas. The dust collector bag assembly rotates while filtering, which can remove water stains adhering to the dust collector bag assembly and directly promote the purification effect of the dust collector bag assembly.

[0038] 2: The reciprocating speed control baffle can control the flow rate as the air passes through the exhaust pipe. At the same time, during the movement of the speed control baffle, the oscillating component can drive the exhaust pipe to perform intermittent reciprocating oscillations of a certain amplitude, which can effectively improve the contact effect between gas and water, thereby improving the spray purification effect on the exhaust gas.

[0039] 3: By using a periodically rotating screw, the purification screen cylinder is controlled to swing back and forth at a certain angle, effectively scraping away larger dispersed particles intercepted on its surface, ensuring the purification effect of the purification screen cylinder.
