Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a deodorizing device for sewage treatment. Background Art

[0002] The main reason for the odor of sewage during sewage treatment is the continuous fermentation of organic compounds, which creates foul-smelling gases. Whether it is industrial wastewater or domestic wastewater, it contains a large amount of organic matter. When it is sent to the sewage treatment plant, complex biochemical reactions will occur, making the sewage smell bad, and organic volatile gases themselves have odors. The concentration of these malodorous gases changes with temperature. The higher the temperature, the faster the water and harmful gases evaporate, and the higher the concentration of malodorous gases. The odor in the sewage treatment process mainly comes from the treatment tank, sedimentation tank and aeration tank.

[0003] After searching, the patent document with publication number: CN215463117U discloses a deodorization device for a sewage treatment pool, which is provided with an air pump, a placement box and an adsorption plate. The air pump extracts the odor generated inside the pool body through an air extraction pipe, and then discharges it to the purification box through an exhaust pipe for centralized treatment, which is convenient for subsequent work and improves the practicality of the device. The placement box is used to place a deodorant, which is fully mixed with the odor to accelerate the decomposition and emission of the odor. However, there are still the following disadvantages in actual use: after the exhaust pipe is discharged into the purification box, since there is no flow channel between the deodorant and the adsorption plate, the odor cannot pass through in sequence, causing the gas to be adsorbed from the adsorption plate first, mainly because the gas is not easy to sink after being discharged, and the odor cannot be fully contacted with the deodorant, causing the odor to react too slowly with the deodorant. When the deodorization is carried out by the adsorption plate alone in the future, it causes frequent shutdowns to replace the adsorption plate, and the deodorization effect is low.

One end of the air intake pipe 6 is docked with the existing fan, and the input end of the fan is docked with the cover of the sealed sewage tank body. The odor generated by the existing sewage tank body is transported to the air intake pipe 6 through the fan. A rotary joint 7 is fixedly sleeved on the bottom outer wall of the air intake pipe 6. A T-tube 8 is fixedly connected to the bottom of the rotary joint 7. The rotary joint 7 assists the T-tube 8 in air intake and rotation. A through hole is opened on the top of the treatment box 1. The inner wall of the through hole is rotatably connected to the outer wall of the T-tube 8.

[0025] The outer wall fixed sleeve of the T-tube 8 is provided with a slave gear 9, the outer wall fixed sleeve of the T-tube 8 is provided with a bearing, the outer ring of the bearing is fixedly connected to the inner wall of the processing box 1, the bearing assists the T-tube 8 to rotate, the outer wall of the processing box 1 is hinged with an L-shaped side door 18, and the outer wall of the L-shaped side door 18 is fixedly connected with a handle 19.

[0026] A driving mechanism is provided inside the docking frame 3, and the driving mechanism includes a motor 10. The inner wall of the docking frame 3 is fixedly connected to the outer wall of the motor 10. The outer wall of the output shaft of the motor 10 is fixedly sleeved with a main gear 11. The main gear 11 is meshedly connected with the slave gear 9. The motor 10 drives the main gear 11 and the slave gear 9 to rotate, thereby realizing the rotation of the T-tube 8 to mix the liquid.

[0027] An adsorption mechanism is provided inside the processing box 1, and the adsorption mechanism includes two mesh frames 15. A partition 12 is fixedly connected inside the processing box 1. A rectangular groove is provided on the outer wall of the partition 12. A circular frame 13 is rotatably connected to the inner wall of the rectangular groove. A shaft is fixedly installed on the outer wall of the circular frame 13. The circular frame 13 is rotatably connected to the rectangular groove through the shaft, and the gap between the rectangular groove and the circular frame 13 is sealed.

[0028] Two circular screens 14 are fixedly inlaid on the bottom outer wall of the circular frame 13. The tops of the two circular screens 14 are in contact with the bottoms of two mesh frames 15 respectively. The circular screens 14 support the mesh frames 15.

[0029] Working principle: when in use, the water pump operates to transport the liquid mixed with the deodorant into the treatment box 1 through the liquid inlet pipe 4, and the liquid is separated from the block honeycomb activated carbon 16 by the water baffle 2. The odor is pumped into the air inlet pipe 6 through the existing fan, and the odor enters the T-tube 8 through the air inlet pipe 6. The odor is discharged from the bottom ends of the T-tube 8. The odor enters the liquid mixed with the deodorant, and the pressure of the odorous airflow is much greater than the water pressure of the liquid; the operation of the motor 10 drives the main gear 11 to rotate, the rotation of the main gear 11 drives the rotation of the slave gear 9, and the rotation of the slave gear 9 drives the T-tube 8 to rotate. The rotation of the T-tube 8 causes the airflow to enter the liquid from the T-tube 8 to generate bubbles. At the same time, the liquid is stirred by the T-tube 8 to make the odor evenly react with the liquid mixed with the deodorant. The reacted odor enters one of the water baffles 2. In the mesh frame 15, as the gas is continuously transported in the treatment box 1, the internal air pressure is relatively high, and the odor after the reaction is discharged from the circular screen 14 and the air outlet filter 17 through multiple block honeycomb activated carbons 16. In this process, multiple block honeycomb activated carbons 16 adsorb molecules in the odor on the surface of the porous medium, so that the odorous substances are transferred from the gas phase to the solid phase, thereby achieving the purpose of removing the odor; at the same time, when multiple block honeycomb activated carbons 16 need to be replaced, open the L-shaped side door 18 and rotate the circular frame 13 to switch the unused multiple block honeycomb activated carbons 16 in another mesh frame 15 with the previous one, and switch the used multiple block honeycomb activated carbons 16 to the vicinity of the L-shaped side door 18, take the mesh frame 15 and the used multiple block honeycomb activated carbons 16 out of the circular frame 13, and add new multiple block honeycomb activated carbons 16 to form a non-stop replacement.
