Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a biological deodorization device for wastewater treatment. Background Technology
[0002] Biological deodorization devices attach microorganisms to the surface of porous media packing and allow polluted air to undergo biological purification in the filter bed layer. Volatile organic pollutants are adsorbed on the pore surface and consumed by the microorganisms in the pores. The metabolic life activities of the microorganisms are used to transform the harmful substances in the exhaust gas into simple inorganic substances and cytoplasm and degrade them into carbon dioxide, water and neutral salts.
[0003] During wastewater treatment, various harmful gases with pungent odors are mixed in with the wastewater. These harmful gases are easily leaked into the wastewater treatment environment while the wastewater is being filtered, causing pollution to the working environment. Therefore, it is necessary to use a biological deodorization device to treat the pungent harmful gases emitted from the wastewater. However, when using a biological deodorization solution to degrade the pungent harmful gases in the wastewater, the decomposition efficiency of the biological deodorization solution is low, which easily leads to some pungent harmful gases leaking out from the exhaust pipe. Therefore, a wastewater treatment biological deodorization device is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a biological deodorization device for wastewater treatment, which solves the problem that the biological deodorization solution has a low efficiency in degrading irritating and harmful gases in wastewater, and that some irritating and harmful gases are easily leaked out from the exhaust pipe during the process of using biological deodorization solution to degrade irritating and harmful gases in wastewater.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A biological deodorization device for wastewater treatment includes a device box, a blower, and an air inlet pipe. The blower is fixedly connected to the outside of the device box, and the air inlet pipe is fixedly connected to the outside of the blower. A biological deodorization plate is fixedly connected to the inside of the device box, and a partition is fixedly connected to the inside of the device box. An exhaust pipe is continuously connected to the inside of the device box, and a drain pipe is continuously connected to the inside of the device box. A liquid inlet pipe is fixedly connected to the inside of the liquid inlet pipe, and a fixed shell is continuously connected to the outside of the liquid inlet pipe. An air supply pipe is continuously connected to the inside of the fixed shell, and a rotating sealing ring is fixedly connected to the inside of the fixed shell. A rotating shaft is fixedly connected to the inner ring of the rotating sealing ring, and a sealed bearing is fixedly connected to the outside of the rotating shaft. A motor is fixedly connected to the rotating shaft via a motor spindle, and a stirring rod is fixedly connected to the outside of the rotating shaft. A nozzle is fixedly connected to the outside of the stirring rod.
[0007] Preferably, the partition divides the device box into two spaces, and a number of biological deodorizing plates are fixedly connected at equal intervals on the outer side of the partition. An air supply pipe is fixedly connected on the inner side of the partition, and the air supply pipe is positioned above the highest biological deodorizing plate.
[0008] Preferably, the inner side of the rotating shaft has a channel and two holes. The position of the hole corresponding to the gas supply pipe on the inner side of the rotating shaft is higher than the position of the hole corresponding to the liquid inlet pipe on the inner side of the rotating shaft. The two holes on the inner side of the rotating shaft are located inside the fixed shell. The gas supply pipe or liquid inlet pipe is sequentially connected to the inner space of the fixed shell, the inner side of the rotating shaft, the stirring rod, and the nozzle.
[0009] Preferably, there are two stirring rods, which are symmetrically arranged outside the rotating shaft and located below the drain pipe. Several nozzles are evenly distributed on the stirring rods in opposite directions around the axis of rotation.
[0010] Preferably, there are two rotary sealing rings, which are symmetrically arranged inside the fixed shell, and the rotary shaft is fixedly connected to the device box through a sealing bearing.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, a biological deodorization device is configured with a biological deodorization plate, a partition, an inlet pipe, a fixed shell, an air supply pipe, a rotating sealing ring, a rotating shaft, a motor, a stirring rod, and a nozzle. During the treatment of irritating and harmful gases in wastewater using this biological deodorization device, a blower transports the irritating and harmful gases from the wastewater to the inner side of one space within the device housing. This allows some of the irritating and harmful gases to be adsorbed by the biological deodorization plate and then enter the inner side of the fixed shell through the air supply pipe. Simultaneously, the inlet pipe introduces biological deodorizing liquid into the inner side of the fixed shell. The irritating and harmful gases inside the fixed shell and the biological deodorizing liquid then converge inside the rotating shaft through two holes, respectively. As the rotating shaft rotates, the gases enter the stirring rod and are then discharged from the nozzle into the biological deodorizing liquid at the bottom of the space on the other side of the device housing. This allows the irritating and harmful gases in the wastewater to fully fuse and degrade with the biological deodorizing liquid under the action of the stirring rod. This device effectively improves the fusion and degradation efficiency of the biological deodorizing solution for irritating and harmful gases in wastewater and reduces the probability of some irritating and harmful gases leaking out from the exhaust pipe.

[0020] Please see Figure 1-4 This utility model provides a technical solution:
[0021] A biological deodorization device for wastewater treatment includes a device box 1, a blower 2, and an air inlet pipe 3. The blower 2 is fixedly connected to the outside of the device box 1, and the air inlet pipe 3 is fixedly connected to the outside of the blower 2. A biological deodorization plate 4 is fixedly connected to the inside of the device box 1, and a partition 5 is fixedly connected to the inside of the device box 1. An exhaust pipe 6 is connected through the inside of the device box 1, and a drain pipe 7 is connected through the inside of the device box 1. An inlet pipe 8 is fixedly connected to the inside of the inlet pipe 8, and a fixed shell 9 is connected through the outside of the inlet pipe 8. An air supply pipe 10 is connected through the inside of the fixed shell 9, and a rotating sealing ring 11 is fixedly connected to the inside of the fixed shell 9. A rotating shaft 12 is fixedly connected to the inner ring of the rotating sealing ring 11, and a sealing bearing 13 is fixedly connected to the outside of the rotating shaft 12. A motor 14 is fixedly connected to the rotating shaft 12 via a main shaft, and a stirring rod 15 is fixedly connected to the outside of the rotating shaft 12. A nozzle 16 is fixedly connected to the outside of the stirring rod 15.
[0022] A partition 5 divides the device box 1 into two spaces. Several biological deodorizing plates 4 are fixedly connected at equal intervals on the outer side of the partition 5. An air supply pipe 10 is fixedly connected to the inner side of the partition 5, positioned above the highest biological deodorizing plate 4 to facilitate efficient and thorough degradation of irritating and harmful gases in the wastewater. A channel and two holes are opened on the inner side of the rotating shaft 12. The hole on the inner side of the rotating shaft 12 corresponding to the air supply pipe 10 is higher than the hole on the inner side of the rotating shaft 12 corresponding to the liquid inlet pipe 8. The two holes on the inner side of the rotating shaft 12 are located inside the fixed shell 9. The air supply pipe 10 or the liquid inlet pipe 8 are connected to the space inside the fixed shell 9, the inner side of the rotating shaft 12, the stirring rod 15, and the nozzle 1. The sequential connection of 6 can improve the fusion and degradation efficiency of irritating and harmful gases in sewage; there are two stirring rods 15, which are symmetrically arranged outside the rotating shaft 12 and below the drain pipe 7. Several nozzles 16 are evenly distributed in opposite directions around the axis of the rotating shaft 12, so that the irritating and harmful gases in sewage can be fully fused with the biological deodorizing liquid; there are two rotating sealing rings 11, which are symmetrically arranged inside the fixed shell 9. The rotating shaft 12 is fixedly connected to the device box 1 through the sealing bearing 13, which can ensure a relatively sealed space between the fixed shell 9 and the rotating shaft 12.
[0023] Working Process: During use, the equipment is powered by an external power source. When using this biological deodorization device to treat irritating and harmful gases in wastewater, the started blower 2 transports the irritating and harmful gases from the wastewater to one of the spaces inside the device box 1 through the air inlet pipe 3. This space is equipped with several biological deodorization plates 4. As the irritating and harmful gases from the wastewater rise and pass through the biological deodorization plates 4, some of the harmful substances in the irritating and harmful gases are filtered and absorbed by the biological deodorization plates 4. Furthermore, the irritating and harmful gases from the wastewater that have passed through all the biological deodorization plates 4 are further filtered and absorbed by the continuous action of the blower 2. Below, the gas can enter the space on the other side of the device box 1 through the gas supply pipe 10 fixedly connected to the inside of the partition 5. The other end of the gas supply pipe 10 is connected to the fixed shell 9. Through the gas supply pipe 10, the irritating and harmful gas of the sewage is transported to the inside of the fixed shell 9. After the irritating and harmful gas of the sewage enters the inside of the fixed shell 9 through the sealed space formed by the rotating sealing ring 11 and the rotating shaft 12, the irritating and harmful gas of the sewage can be transported to the channel inside the rotating shaft 12 through the hole starting from the inside of the rotating shaft 12. At this time, the biological deodorizing liquid is transported to the inside of the fixed shell 9 through the liquid inlet pipe 8. The biological deodorizing liquid in the space can be directly fed into the channel of the rotating shaft 12 along with the irritating and harmful gases from the sewage through another hole opened on the inner side of the rotating shaft 12. This allows the biological deodorizing liquid and the irritating and harmful gases from the sewage to gradually mix in the rotating shaft 12. At this time, the rotating shaft 12 can rotate stably in the device box 1 under the action of the motor 14 in a fixed position. At the same time, the rotating shaft 12 can rotate stably in the fixed shell 9 in a fixed position through the rotating sealing ring 11. This allows the rotating shaft 12 to drive the stirring rod 15 fixedly connected to its outside to move in the biological deodorizing liquid stored in the device box 1. As the stirring rod 15 rotates, the biological deodorizing liquid conveyed inside the rotating shaft 12 and the irritating and harmful gases from the sewage are discharged from the nozzle 16 through the stirring rod 15 and dissolved in the biological deodorizing liquid inside the device box 1. The sewage gases treated by the biological deodorizing liquid can be discharged from the exhaust pipe 6, and excess biological deodorizing liquid can be discharged from the drain pipe 7. This device effectively improves the fusion and degradation efficiency of the biological deodorizing solution for irritating and harmful gases in sewage and reduces the probability of some irritating and harmful gases leaking out from the exhaust pipe 6.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
