By setting a spraying mechanism, the problem that only larger particles in the smoke can be removed, gaseous pollutants cannot be directly removed, and the collected dust can cause a short circuit between the discharge electrode and the collection electrode, requiring regular cleaning, which increases the maintenance cost.

[0009] Furthermore, an air inlet is fixedly mounted on the front side of the rectangular bottom plate, and a dust cover is fixedly mounted on the front side of the air inlet.

[0010] Furthermore, a cross support frame is fixedly installed on the inner wall of the dust removal box, a rotating shaft is rotatably installed on the cross support frame, a motor is fixedly installed on the top of the cross support frame, the rotating shaft passes through the cross support frame and is fixedly connected to the output shaft of the motor, and a fan is fixedly sleeved on the rotating shaft.

[0011] Furthermore, the mixing mechanism includes a plurality of mixing components and limiting components. The mixing component includes a round roller fixedly mounted on a rotating shaft. Two clamping blocks are fixedly mounted on the outer wall of the round roller. Slide grooves are respectively provided on the sides of the two clamping blocks close to each other, and mixing plates are slidably mounted in the two slide grooves.

[0013] The utility model has the following beneficial effects:

[0014] 1. By setting up a spraying mechanism, when the flue gas outside the dust removal box enters the dust removal box, the water pump can be started. The water pump transfers the catalyst into the catalyst storage box through the connecting pipe, so that it enters the catalyst tube through the water inlet, and then is evenly sprayed out by the catalyst nozzle, so that the aggregation between particles can be promoted, the particle size can be increased, and the dust removal efficiency can be improved. In particular, for fine particles that are difficult to capture with traditional dust removal technology, the method of spraying catalysts can significantly improve their removal effect, and can also convert pollutants into harmless or easier to handle substances, thereby reducing the risk of secondary pollution;

[0015] 2. By setting up a mixing mechanism, when the catalyst is sprayed, the motor can be started. The motor drives the round roller on the rotating shaft and then drives the mixing plate on the clamping block to rotate, so that the flue gas and catalyst in the dust removal box are evenly mixed, thereby making the dust removal efficiency higher and ensuring that each catalyst particle can be in contact with sufficient flue gas. This means that the pollutants in the flue gas can be more comprehensively captured and converted by the catalyst, which is conducive to avoiding local overheating or incomplete reaction, thereby improving the service life of the catalyst and the overall reaction efficiency.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
