[0002] At present, there are many processes and devices for sludge treatment and disposal. Among them, the hydrothermal hydrolysis process directly hydrolyzes sludge with high-temperature steam, and the generated malodorous gas is much greater than other processes.

[0003] When treating these malodorous gases, the spraying method is generally used for treatment. The spraying method is prone to the phenomenon of insufficient gas deodorization, and the conventional spraying deodorization method is relatively single, resulting in the discharged gas not meeting the emission standards. Therefore, a sludge hydrothermal hydrolysis waste gas deodorization device is proposed. Summary of the Utility Model

[0004] In view of the problems existing in the existing sludge hydrothermal hydrolysis waste gas deodorization device, the present utility model is proposed.

[0005] Therefore, the purpose of the present utility model is to provide a sludge hydrothermal hydrolysis waste gas deodorization device, which solves the problems raised in the background technique.

[0006] In order to achieve the above purpose, the present utility model provides the following technical solutions:

A motor frame is fixedly arranged at the top of the box body. A motor is fixedly arranged inside the motor frame. An output end of the motor is fixedly provided with a rotating pipe extending into the box body. An output end of the suction fan is fixedly provided with an air inlet pipe, and an end of the air inlet pipe is connected to the pipe wall of the rotating pipe. Horizontally and fixedly arranged above the inside of the box body is a partition board. The area above the partition board is a waste heat recovery area, and heat exchange water is arranged inside the waste heat recovery area.

An exhaust pipe is fixedly arranged on a side wall of the box body and above the activated carbon layer.

[0008] Preferably, an air box is fixedly arranged at the top of the box body. The pipe wall of the rotating pipe vertically penetrates through the middle of the air box. One end of the air inlet pipe away from the suction fan is fixedly connected to the side wall of the air box. Air inlet holes are formed in the pipe wall of the rotating pipe and inside the air box.

[0009] Preferably, the gas distribution pipe adopts an L-shaped pipe, and a plurality of uniformly distributed gas distribution holes are formed in the pipe wall of the gas distribution pipe.

[0010] Preferably, a support net is fixedly arranged inside the box body, and the activated carbon layer is located above the support net.

[0011] Preferably, the pipe wall of the rotating pipe is rotatably connected to both the air box and the partition through sealed bearings.

[0015] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0016] In the present utility model, through the provided exhaust fan, the gas is inhaled into the interior of the intake pipe through the exhaust fan, then discharged into the interior of the rotating pipe, and finally discharged into the interior of the microbial liquid (yeast) through the air distribution pipe at the lower end of the rotating pipe, so that the gas first reacts with the microbial liquid (yeast) to perform deodorization treatment. After the gas is deodorized by the microbial liquid (yeast) and discharged, until the gas passes through the activated carbon layer for adsorption deodorization treatment, and finally discharged outward through the exhaust pipe.

[0017] In the present utility model, through the provided motor, the rotation of the rotating pipe and the air distribution pipe can be adjusted when the motor works, so that the gas is evenly distributed in the microbial liquid (yeast).

The upper part of the partition board 7 is a waste heat recovery area, and there is heat exchange water inside the waste heat recovery area. The lower part of the partition board 7 is a deodorization area, and there are microbial liquid and an activated carbon layer 8 inside the deodorization area. A support net 15 is fixedly arranged inside the box body 1. The activated carbon layer 8 is located above the support net 15, and the support net 15 can hold up and place the activated carbon layer 8. The pipe wall of the rotating pipe 5 and inside the preheating recovery area is fixedly provided with a heat exchange pipe 9.

An exhaust pipe 11 is fixedly arranged on the side wall of the box body 1 and above the activated carbon layer 8. An exhaust gas detector 21 is arranged on the pipe wall of the exhaust pipe 11. The exhaust gas detector 21 can detect the discharged gas to ensure that the discharged gas meets the emission standards.

[0028] The gas is inhaled into the interior of the intake pipe 6 through the exhaust fan 2, then discharged into the interior of the rotating pipe 5, and finally discharged into the interior of the microbial liquid (yeast) through the air distribution pipe 10 at the lower end of the rotating pipe 5, enabling the gas to react with the microbial liquid (yeast) first, so as to carry out deodorization treatment. After the gas is deodorized by passing through the microbial liquid (yeast) and discharged, until the gas passes through the activated carbon layer 8 for adsorption deodorization treatment, and finally discharged outward through the exhaust pipe; when the motor 4 works, it can drive the rotating pipe 5 and the air distribution pipe 10 to rotate, so that the gas is evenly distributed in the interior of the microbial liquid (yeast). At the same time, the air distribution pipe 10 can play a role in stirring the microbial liquid (yeast), accelerating the contact effect between the gas and the microbial liquid (yeast), and improving the deodorization efficiency; before the gas is deodorized, its temperature is relatively high, and the gas will enter the interior of the heat exchange pipe 9, and heat exchange with water through the heat exchange pipe 9, so that the temperature of the water rises, thereby recovering the waste heat of the gas.

An intake hole 13 is provided on the pipe wall of the rotating pipe 5 and inside the gas box 12. During the rotation of the rotating pipe 5, the gas will enter the interior of the gas box 12 and then enter the interior of the rotating pipe 5 through the intake hole 13.
