One end of the first pipe body is communicated with a spray head, and the other end of the first pipe body is communicated with a water pump. The bottom of the water pump is fixedly connected with a liquid medicine tank.

[0004] However, it still has the following drawbacks in actual use:

[0005] 1. When the above-mentioned biochemical waste gas treatment device is in use, the liquid medicine after reacting with the biochemical waste gas is discharged through the water outlet pipe. However, there is still unreacted liquid medicine after the reaction with the biochemical waste gas in this way, and direct discharge will cause waste, affecting the utilization efficiency of the liquid medicine;

[0006] 2. When the above-mentioned biochemical waste gas treatment device is in use, the liquid medicine is sprayed through the spray head to react with the biochemical waste gas. However, due to the relatively fast flow rate of the introduced biochemical waste gas, the reaction rate and effect of the biochemical waste gas will be affected. Therefore, we provide a biochemical waste gas treatment device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] Please refer to Figures 1 to 4 , the present invention is a biochemical waste gas treatment device, including a tower body 1, and a spraying assembly 2 is arranged behind the tower body 1; the spraying assembly 2 includes a recovery tank 201 and a first liquid outlet pipe 201a arranged at the bottom of the rear end face thereof, and a water pump 202 and a liquid medicine tank 203 are respectively arranged on both sides behind the recovery tank 201.

[0034] Specifically, an air inlet pipe 101 is arranged at the bottom of one outer wall of the tower body 1, a waste gas pipe 102 is arranged at the center position of the bottom of the tower body 1, an air outlet pipe 105 is arranged at the top of the other outer wall of the tower body 1, the other end of the air outlet pipe 105 is connected to an air delivery pipe 106a through a pipe joint, the other end of the air delivery pipe 106a is connected to a fan 106 through a pipe joint, the air outlet end of the fan 106 is connected to the air inlet end of a purification tank 107 through a pipe joint, the air outlet end of the purification tank 107 is connected to an exhaust pipe 108 and a return air pipe 109 through a three-way joint, the other end of the return air pipe 109 is connected to the air inlet pipe 101 and the waste gas pipe 102 through a three-way joint, a second liquid outlet pipe 203a is arranged at the bottom of the front end face of the liquid medicine tank 203, the other end of the second liquid outlet pipe 203a is connected to a connecting pipe 203b through a pipe joint, the other end of the connecting pipe 203b is connected to the first liquid outlet pipe 201a and the liquid inlet end of the water pump 202 through a three-way joint, the liquid outlet end of the water pump 202 is connected to a liquid delivery pipe 202a through a pipe joint, and the other end of the liquid delivery pipe 202a is connected to a spray head 204 through a pipe joint, and the spray head 204 is located at the top inside the tower body 1.

[0035] Furthermore, the pipe joint and the three-way joint both play a role in pipeline connection. The operation of the fan 106 can draw the biochemical waste gas in the tower body 1 into the purification tank 107 for further purification of the biochemical waste gas. The recovery tank 201 can recover the liquid medicine discharged from the liquid discharge pipe 103 to facilitate the subsequent recycling of the unreacted liquid medicine and improve the utilization efficiency of the liquid medicine.

[0036] The operation process of this embodiment is as follows: When in use, biochemical waste gas is introduced through the waste gas pipe 102. The biochemical waste gas enters the tower body 1 through the air inlet pipe 101. Then, the water pump 202 is started. The water pump 202 operates to extract the liquid medicine tank 203 through the second liquid outlet pipe 203a, and then extracts the liquid medicine to the nozzle 204 through the connecting pipe 203b and the liquid delivery pipe 202a. Then, the nozzle 204 sprays the liquid medicine to be mixed and purified with the biochemical waste gas. The incompletely purified liquid medicine will fall to the bottom inside the tower body 1. Then, the liquid medicine will fall into the recycling box 201 below through the drain pipe 103. When the water pump 202 operates, the liquid medicine inside the recycling box 201 can be extracted through the first liquid outlet pipe 201a for reuse, thereby improving the utilization efficiency of the liquid medicine and avoiding waste of the unreacted liquid medicine.

[0037] Embodiment 2

[0038] Please refer to Figure 3 and Figure 5 Based on Embodiment 1, the difference from the first embodiment is: A honeycomb plate 104 and a flow disturbance component 3 are provided. The flow disturbance component 3 includes a motor 301 and a rotating shaft 301a installed on its output shaft through a coupling. The rear end of the rotating shaft 301a penetrates through the bearing on the front end face of the tower body 1 and is connected to the bearing on the rear end face of the inner wall of the tower body 1. The outer wall of the rotating shaft 301a is evenly spaced with flow disturbance plates 302 from front to back, solving the problem that in the existing biochemical waste gas treatment device, when spraying liquid medicine through a nozzle to react with the biochemical waste gas, due to the relatively fast flow rate of the introduced biochemical waste gas, the reaction rate and effect of the biochemical waste gas will be affected.

[0039] Furthermore, when the motor 301 operates, it drives the rotating shaft 301a to rotate under the action of the coupling, thereby driving the multiple flow disturbance plates 302 on the outer wall of the rotating shaft 301a to rotate, thus disturbing the biochemical waste gas inside the tower body 1 and slowing down the flow rate of the biochemical waste gas.

[0040] The operation process of this embodiment is as follows: When the liquid medicine is sprayed through the nozzle 204 to react with the biochemical waste gas, the biochemical waste gas will slow down its flow rate under the action of the honeycomb plate 104 and react with the sprayed liquid medicine at the same time. Then, the motor 301 is started. The output shaft of the motor 301 rotates to drive the rotating shaft 301a to rotate through the coupling. There are multiple flow disturbance plates 302 arranged on the outer wall of the rotating shaft 301a. The rotation of the flow disturbance plates 302 will disturb the internal biochemical waste gas, so that the biochemical waste gas can rotate in one direction inside the tower body 1 and continuously carry out purification reactions, thereby improving the purification effect of the biochemical waste gas. The purified biochemical waste gas can be introduced into the purification box 107 through the air outlet pipe 105 and the air delivery pipe 106a under the action of the fan 106, improving the purification effect of the biochemical waste gas. Then, it can re-enter the tower body 1 through the return air pipe 109, and the biochemical waste gas can be purified in multiple cycles.
