Meanwhile, the rotation of the spray frame 1003 drives the baffle 1005 to rotate, so that the baffle 1005 intermittently seals the communicating pipe 5, and when the communicating pipe 5 is sealed, the residence time of the waste gas in the purifying tower 1 is increased, the reaction time of the waste gas and ammonia water is increased, the mixing efficiency of the waste gas and the ammonia water is improved, the internal air pressure of the purifying tower 1 can be increased, the waste gas in the denitration cylinder 6 is prevented from flowing back into the purifying tower 1, and when the communicating pipe 5 is not sealed, the internal air pressure of the purifying tower 1 is increased when the communicating pipe 5 is sealed, the waste gas in the purifying tower 1 can quickly flow into the denitration cylinder 6, and the stable transmission of the gas is ensured;
the treated waste gas enters a denitration cylinder 6 through a communicating pipe 5 for denitration treatment, and the waste gas after denitration treatment is adsorbed and purified by an activated carbon plate in an adsorption box 7 and then is discharged through an exhaust pipe 8, so that the waste gas generated in the ceramic pigment production process is purified;
impurities shaken off on the filter screen 1401 and the filter bag 1303 are accumulated at the inner bottom of the purifying tower 1, and when the impurities are required to be discharged, the dust can be discharged by opening a valve in the dust discharging pipe 9;
and the waste liquid generated by purifying waste gas by ammonia water falls on the guide plate 1201, and when the waste liquid needs to be discharged, the waste liquid can be discharged by opening a valve arranged in the waste discharge pipe 3.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
