The end of the outlet pipe extending into the interior of the deodorizing barrel is fixedly connected to the top of the spiral nozzle.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this invention, the generated odorous gas enters the interior of the deodorizing tank through the exhaust pipe. Acidic and alkaline chemical agents are injected into the bottom of the deodorizing tank. The water pump is turned on, causing the agents to flow into the outlet pipe through the inlet pipe, and then be sprayed out through a spiral nozzle. The odorous gas is evenly distributed through a multi-hole plate distributor. The odorous gas comes into contact with the sprayed agents for deodorization. After deodorization, the odorous gas flows to the connecting pipe, then through activated carbon filler, where it undergoes secondary deodorization. Finally, it is discharged through the outlet pipe. By combining spray deodorization and activated carbon deodorization, the deodorization effect is increased, and the impact of odor on the working environment is reduced.
[0015] 2. In this utility model, pressing the moving block moves the moving plate, which in turn squeezes the connecting spring. The moving plate moves the locking block away from the inside of the slot, allowing the activated carbon stabilizing tube to break free from its locked state. Then, pulling the handle removes the activated carbon stabilizing tube. Pressing the moving block in the new activated carbon stabilizing tube causes the moving plate to retract into the spring slot, placing the activated carbon stabilizing tube on one side of the sealing tube. This allows the moving plate and locking block to enter the groove. Releasing the moving block allows the locking block to re-enter the moving opening through the reset of the connecting spring, thus locking the activated carbon stabilizing tube and activated carbon filler. Simultaneously, the sealing ring enters the sealing groove, and the second sealing strip enters the first sealing strip, facilitating the replacement of the activated carbon filler and reducing the tediousness of replacement, thereby ensuring the deodorization effect.

[0040] Working Principle: Sludge undergoes hydrolysis treatment inside the hot water decomposition reactor 1. The resulting odorous gas enters the deodorization tank 301 through the exhaust pipe 2. Acidic and alkaline chemical agents are injected at the bottom of the deodorization tank 301. The water pump 303 is activated, causing the agents to flow into the outlet pipe 304 through the inlet pipe 302, and then be sprayed out through the spiral nozzle 305. The odorous gas is evenly distributed through the multi-hole plate distributor 306. The odorous gas comes into contact with the sprayed agents for deodorization. After deodorization, the odorous gas flows to the connecting pipe 401, then through the activated carbon filler 502, where it undergoes secondary deodorization. The gas is then discharged through the outlet pipe 403. When the activated carbon filler 502 needs to be replaced, pressing the moving block 511 moves the moving plate 509, which in turn moves the connecting spring 508. When squeezed, the moving plate 509 moves, causing the locking block 510 to move away from the inside of the slot 405, thus releasing the activated carbon stabilizing tube 501 from the locked state. Then, the handle 503 is pulled to remove the activated carbon stabilizing tube 501. The moving block 511 in the new activated carbon stabilizing tube 501 is pressed, causing the moving plate 509 to retract into the spring slot 504. The activated carbon stabilizing tube 501 is placed on one side of the sealing tube 402, so that the moving plate 509 and the locking block 510 enter the inside of the groove 404. Then, the moving block 511 is released, and the locking block 510 is driven back into the moving port 505 by the reset of the connecting spring 508, thereby locking the activated carbon stabilizing tube 501 and the activated carbon filler 502. At the same time, the sealing ring 506 enters the inside of the sealing groove 406, and the second sealing strip 507 enters the inside of the first sealing strip 407.
