Description

Technical Field

[0001] This utility model relates to the field of sewage odor treatment, specifically to a sewage odor treatment device. Background Technology

[0002] Anaerobic microorganisms in wastewater consume organic matter and produce gases with odors. Wastewater treatment can be carried out using methods such as adsorption, biological filtration, chemical methods, and combustion. Among these, chemical methods utilize relevant agents to react with nitrogen- and sulfur-containing substances in wastewater exhaust gases that produce odors, thereby eliminating these substances and removing the odor from the exhaust gases. Chemical methods are a commonly used and relatively mature treatment method. However, one of its drawbacks is the insufficient utilization rate of the agents, resulting in serious waste.

[0003] Conventional chemical deodorization methods employ wastewater treatment tanks or reaction pools, where collected wastewater and exhaust gases are introduced from a point within the container. The exhaust gases then pass through a chemical solution and are expelled. Odor-causing substances pass through the chemical solution and are reacted by the agent. As the gas enters the liquid, it rises. This results in lower reaction efficiency for the chemical solution located far from the gas outlet area. Although the diffusion of the solute in the solution eventually becomes relatively uniform, the amount of chemical used cannot be precisely quantified under normal operation. Consequently, once a slowdown in the reaction is detected, the chemical solution may be replaced before it is fully utilized, leading to waste. Therefore, a wastewater treatment odor control device is provided. Utility Model Content

[0004] I. Technical problems to be solved

[0005] The technical problem this invention aims to solve is that in the chemical treatment of sewage odor, there is insufficient utilization of the chemical solution, leading to waste.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a sewage treatment odor treatment device, including a reaction tank, with an inlet pipe and a drain pipe respectively connected to the upper and lower ends of the reaction tank, a solenoid valve installed on the drain pipe, an odor input pipe installed on the top of the reaction tank, and a discharge port reserved at the top of the reaction tank for transporting the deodorized waste gas to other equipment.

[0007] The reaction vessel is spherical, and its interior is rotatably connected to a gas supply pipe whose top is mounted to the end of the gas inlet pipe via a rotating sealing assembly. A rotating assembly for driving the gas supply pipe to rotate is installed on the reaction vessel.

[0008] Below the gas supply pipe is an exhaust pipe that is inclined inside the bottom of the reaction tank. The reaction tank is equipped with a lifting component that drives the exhaust pipe to change its inclination and expands the exhaust range of the exhaust pipe port.

[0009] Furthermore, the rotating assembly includes a drive shaft rotatably connected to the top of the reaction vessel, a No. 1 motor that drives and cooperates with the drive shaft rotatably installed above the reaction vessel, a main gear installed on the drive shaft rotatably, and a secondary gear that meshes with the main gear is connected to the outer side of the top of the gas supply pipe.

[0010] Furthermore, the lifting assembly includes a screw rotatably connected to the top of the reaction vessel, a drive assembly for driving the screw to rotate is installed on the reaction vessel, a screw cylinder is threadedly connected below the screw, a limiting assembly for preventing the screw cylinder from rotating is installed on the reaction vessel, a drive disc is installed between the bottom of the screw cylinder and the gas supply pipe, and a guide rod is rotatably connected between one side of the drive disc and the end of the exhaust pipe near the exhaust port.

[0011] Furthermore, the drive assembly includes a second drive shaft rotatably connected to the top of the reaction vessel, a second motor that drives and cooperates with the second drive shaft is installed above the reaction vessel, a main pulley is installed on the second drive shaft, a secondary pulley is installed on the top of the screw, and a drive belt is connected between the main pulley and the secondary pulley.

[0012] Furthermore, the limiting mechanism includes a through hole at the top of the reaction vessel, and a slide rod is connected to the screw cylinder through the through hole and slidably connected to the reaction vessel.

[0013] Furthermore, the inner side of the drive disk contains multiple sliding grooves, and the outer side of the air supply pipe is connected to multiple sliders that are embedded in the sliding grooves to achieve synchronous rotation of the drive disk. The drive disk is provided with an annular groove, and the bottom end of the screw cylinder extends into the annular groove and is connected to a circular support disk.

[0014] Furthermore, a corrosion-resistant flexible connecting pipe that cooperates with the lifting assembly is installed between the gas supply pipe and the exhaust pipe.

[0015] The advantages of this invention compared to existing technologies are as follows: The device uses a roughly spherical reactor vessel, on which a rotating assembly and a lifting assembly are installed. This causes the exhaust pipe, which is inclined inside the vessel, to rotate and repeatedly sway up and down in the liquid during the exhaust process. This ensures that the exhaust gas is evenly distributed in the bottom area of ​​the vessel, and that the path of the exhaust gas rising in the liquid is relatively evenly distributed within the reactor vessel. This actively increases the contact between the odorous substances and the reagent, thereby improving the utilization rate of the reagent and reducing waste. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a sewage treatment odor treatment device, combined with the attached... Figure 1-2 The reaction vessel includes a reaction tank 1, with an inlet pipe 22 and a drain pipe 23 connected to the upper and lower ends of the reaction tank 1, respectively. A solenoid valve 24 is installed on the drain pipe 23. An inlet pipe 2 for odor input into the reaction tank 1 is installed on the top of the reaction tank 1. An exhaust port is reserved at the top of the reaction tank 1 for transporting the deodorized waste gas to other equipment.

[0026] The reaction tank 1 contains appropriate amounts of chemical reagents. By passing the odorous waste gas collected from sewage treatment into the reagent reaction liquid, the reagents and the relevant substances in the odorous gas come into contact with each other, fuse and react chemically, thereby removing the odorous substances in the waste gas and achieving the effect of sewage odor treatment.

[0027] Combined with appendix Figure 3 The spherical reaction vessel 1 is rotatably connected to a gas supply pipe 3, the top of which is mounted to the end of the gas inlet pipe 2 via a rotary sealing assembly. Figure 5-6 The reaction vessel 1 is equipped with a rotating assembly for driving the gas pipeline 3 to rotate. The rotating assembly includes a drive shaft 6 rotatably connected to the top of the reaction vessel 1. A motor 7 is installed above the reaction vessel 1 and drives the drive shaft 6. A main gear 8 is installed on the drive shaft 6. A secondary gear 9 that meshes with the main gear 8 is connected to the outer side of the top of the gas pipeline 3.

[0028] In order to prevent the odor from spreading rapidly in the reagent and achieve a more uniform distribution and rapid reaction, the tilted exhaust port is first rotated in the tank to change its position in the tank, and centrifugal force is used to distribute the odor over a large area in the reagent.

[0029] Combined with appendix Figure 3-4 Below the gas supply pipe 3, an exhaust pipe 5 is inclined inside the bottom of the reaction tank 1. A lifting assembly is installed on the reaction tank 1 to drive the exhaust pipe 5 to change its inclination, thereby expanding the exhaust range at the port of the exhaust pipe 5. The lifting assembly includes a screw 15 rotatably connected to the top of the reaction tank 1, combined with an attached... Figure 5-6 The reaction vessel 1 is equipped with a drive assembly that drives the screw 15 to rotate. The drive assembly includes a second transmission shaft 16 rotatably connected to the top of the reaction vessel 1. A second motor 17 is installed above the reaction vessel 1 and is mutually driven and cooperates with the second transmission shaft 16. A main pulley 18 is installed on the second transmission shaft 16. A secondary pulley 20 is installed on the top of the screw 15. A transmission belt 19 is connected between the main pulley 18 and the secondary pulley 20.

[0030] A screw cylinder 14 is threadedly connected below the screw 15. A limiting component for preventing the screw cylinder 14 from rotating is installed on the reaction vessel 1. The limiting mechanism includes a through hole 26 at the top of the reaction vessel 1. A slide rod 25 is connected to the screw cylinder 14 and slides through the through hole 26 to the reaction vessel 1.

[0031] Combined with appendix Figure 3-4 A drive disc 10 is installed between the bottom of the screw barrel 14 and the air supply pipe 3. A guide rod 21 is rotatably connected between one side of the drive disc 10 and the end of the exhaust pipe 5 near the exhaust port. A corrosion-resistant flexible connecting pipe 4 that cooperates with the lifting assembly is installed between the air supply pipe 3 and the exhaust pipe 5.

[0032] The screw barrel 14, which has a limiting condition, rotates and rises and falls with the screw 15, or lifts or pushes the drive disc 10 at one end of the guide rod 21 to move up and down together. This changes the state of the triangle formed by the lower half of the gas supply pipe 3, the exhaust pipe 5, and the guide rod 21, so that the exhaust port can move directly around the bottom of the gas supply pipe 3 and the edge of the reaction tank 1. To match this movement, the bottom of the reaction tank 1 adopts a spherical structure. The exhaust gas from the exhaust port can obtain more upward paths in the liquid, allowing the reagent solution to fully absorb the odor substances in the exhaust gas, achieving a more efficient deodorization effect, thereby improving the utilization rate of the reagent and reducing the waste of chemical reaction raw materials.

[0033] Combined with appendix Figure 7 The inner side of the drive disk 10 contains multiple sliding grooves, and the outer side of the air supply pipe 3 is connected to multiple sliders 11 that are embedded in the sliding grooves to achieve synchronous rotation of the drive disk 10. The drive disk 10 is provided with an annular groove 12, and the bottom end of the screw cylinder 14 extends into the annular groove 12 and is connected to a circular support disk 13.

[0034] In order to cooperate with the operation described above at the odor exhaust outlet, the exhaust pipe 5 is rotated by the gas supply pipe 3 via the drive disc 10. However, in order to ensure that the lifting assembly fixedly installed on the reaction tank 1 is not affected, the screw cylinder 14 and the drive disc 10 are assembled by embedding a disc into a circular groove to keep them in a certain position. Furthermore, the flexible connecting pipe 4 installed between the gas supply pipe 3 and the exhaust pipe 5 can adapt to the exhaust pipe 5 being in any tilted state and can be effectively connected to the gas supply pipe 3.

[0035] In a specific implementation of this invention, the agent for treating wastewater aeration is injected into the reaction tank 1 through the inlet pipe 22. The solenoid valve 24 can be closed for continuous use within the reaction tank 1, or the solenoid valve 24 can be opened to allow the agent to flow through the reaction tank 1 at a suitable flow rate. Waste gas from wastewater treatment is concentrated and enters the reaction tank 1 through the inlet pipe 2, and is discharged into the agent through the outlet. During this process, the outlet pipe rotates within the agent along with the continuous rotation of the inlet pipe, and simultaneously oscillates up and down to a certain extent due to the action of the lifting component. At this time, waste gas can be discharged from various areas at the bottom of the reaction tank 1 through the outlet. The waste gas rises in the liquid, and substances that emit odors undergo a chemical reaction in the agent, thus being removed. The odor-free waste gas continues to rise and enters the subsequent waste gas treatment equipment from the top discharge port and related pipes.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
