Description

Technical Field

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

[0002] The main reason why sewage treatment plants need odor spray treatment equipment is that they produce a large amount of malodorous gases during operation. These gases not only harm the environment and human health, but may also corrode the equipment. Therefore, effective deodorization measures must be taken.

[0003] Odor spray treatment equipment is a device used to treat odorous gases generated by sewage treatment plants. Its main purpose is to remove harmful substances such as hydrogen sulfide (H2S) and ammonia (NH3) from the odorous gases through chemical and physical methods to meet environmental emission standards. These devices typically employ processes such as "spraying + adsorption" or "alkaline washing + spraying," with specific designs and operating methods varying depending on project requirements.

[0004] Existing odor spraying treatment devices typically pump odor into the spray tower continuously. After the odor comes into contact with the chemical agents, it is discharged outside the spray tower. If the contact time between the odor and the chemical agents inside the spray tower is insufficient, the exhaust gas cannot be stopped from being discharged from the spray tower, resulting in the possibility that the discharged exhaust gas contains harmful gases. The odor decomposition and adsorption effect does not meet expectations. Summary of the Invention

[0005] The purpose of this invention is to provide an odor spraying treatment device for a sewage treatment plant to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An odor spray treatment device for a sewage treatment plant includes an odor collection device, a pretreatment device, a spray purification device, and an emission device. The spray purification device includes a mounting frame and a treatment tank mounted on the mounting frame. A rotating nozzle is rotatably installed inside the treatment tank, and the rotation and feeding of the rotating nozzle are controlled by a drive assembly mounted on the mounting frame.

[0008] The processing tank is provided with an air inlet and an air outlet, and a ball valve is rotatably installed in the air inlet and the air outlet respectively.

[0009] The processing tank is symmetrically provided with mounting bases, and the mounting bases are provided with intermittent adjustment components. The two intermittent adjustment components can control the opening and closing states of the two ball valves respectively.

[0010] The odor spray treatment equipment of the sewage treatment plant as described above: a tank cover is detachably installed on the treatment tank, one end of the rotating nozzle passes through the tank cover and extends out of the tank cover, and a transfer cylinder is provided on the tank cover along the axial direction of the rotating nozzle, and the annular cavity formed by the transfer cylinder can communicate with the cylindrical cavity inside the rotating nozzle.

[0011] The odor spray treatment equipment of the sewage treatment plant as described above: the drive component includes a first motor, and the output shaft of the first motor is fixed to the rotating nozzle;

[0012] It also includes a pumping assembly mounted on the mounting bracket, the pumping assembly having an output end and an input end, the output end being connected to the transfer cylinder via a conduit.

[0013] The odor spray treatment equipment of the sewage treatment plant as described above: the intermittent adjustment component includes a grooved roller rotatably mounted on the mounting base, and the rotation of the grooved roller is driven by a second motor fixed on the mounting base. A movable sleeve is slidably arranged along the axial direction of the grooved roller, and a first push rod and a second push rod are provided on the movable sleeve.

[0014] It also includes an elastic trigger element disposed on the mounting base, and the first push rod and the second push rod can intermittently push the elastic trigger element when they move.

[0015] The odor spray treatment equipment of the sewage treatment plant as described above: the elastic trigger includes a support plate installed on the mounting base, a deflection rod is rotatably provided on one end of the support plate away from the mounting base, and a first limiting block and a second limiting block are symmetrically provided at both ends of the support plate to limit the deflection of the deflection rod;

[0016] It also includes a first spring, one end of which is hinged to the support plate and the other end of which is hinged to the deflection rod.

[0017] As described above, the odor spraying treatment equipment of the sewage treatment plant: when the deflection rod deflects to the balance position of the support plate, it can squeeze the elastic telescopic member set on the mounting frame.

[0018] The odor spraying treatment equipment of the sewage treatment plant described above: a push plate in a U-shape is fixedly connected to the ball valve.

[0019] The odor spray treatment equipment of the sewage treatment plant as described above: the elastic telescopic component includes a plug-in cylinder disposed on the mounting frame, a pressing rod is slidably disposed inside the plug-in cylinder, both ends of the pressing rod pass through the plug-in cylinder respectively, and one end of the pressing rod is hinged to the push plate;

[0020] It also includes a second spring, which is disposed inside the insertion cylinder. One end of the second spring abuts against the inner end of the insertion cylinder, and the other end abuts against the compression rod.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] After the odor enters the treatment tank through the channel on the ball valve, the ball valve at the inlet end rotates relative to the inlet end under the action of the intermittent regulating component to perform a sealing operation. At this time, the drive component is activated, and the drive component controls the delivery of appropriate chemical agents into the rotating nozzle. At the same time, the rotating nozzle rotates, which expands the spray range of the chemical agents and allows the odor to fully contact the chemical agents, thus accelerating the odor treatment efficiency. Subsequently, under the action of the intermittent regulating component, the ball valve at the outlet end performs an opening and closing action, allowing the treated tail gas and residual liquid in the treatment tank to flow into the collection device through the outlet end. The opening and closing of the inlet and outlet ends, under the action of the intermittent regulating component, effectively cooperate with the spraying operation of the rotating nozzle, ensuring that the odor pumped into the treatment tank can fully contact and adsorb the chemical agents before being discharged to the outside, thereby improving the adsorption and decomposition efficiency of odor molecules.

Detailed Implementation

[0030] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0031] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0032] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0033] Please see Figures 1-6 In this embodiment of the present invention, an odor spray treatment device for a sewage treatment plant includes an odor collection device, a pretreatment device, a spray purification device and an emission device. The spray purification device includes a mounting frame 1 and a treatment tank 2 mounted on the mounting frame 1. A rotating nozzle 4 is rotatably arranged inside the treatment tank 2, and the rotation and feeding of the rotating nozzle 4 are controlled by a drive assembly mounted on the mounting frame 1.

[0034] The processing tank 2 is provided with an air inlet 201 and an air outlet 202, and a ball valve 20 is rotatably installed in the air inlet 201 and the air outlet 202 respectively.

[0035] The processing tank 2 is symmetrically provided with mounting bases 9, and the mounting bases 9 are provided with intermittent adjustment components. The two intermittent adjustment components can control the opening and closing states of the two ball valves 20 respectively.

[0036] It should be noted that the bottom of the treatment tank 2 is equipped with a collection device (not shown in this embodiment). The collection device is connected to the gas outlet 202. The collection device can process the exhaust gas and residual gas entering the gas outlet 202, so that the separated exhaust gas can be discharged into the atmosphere.

[0037] In this embodiment, initially, the ball valve 20 on the inlet end 201 is open, and the ball valve 20 on the outlet end 202 is closed. After the odor enters the treatment tank 2 through the channel on the ball valve 20, under the action of the intermittent regulating component, the ball valve 20 on the inlet end 201 rotates relative to perform the blocking operation. At this time, the drive component is started to work. The drive component controls the delivery of suitable chemical agents into the rotating nozzle 4. At the same time, the rotating nozzle 4 rotates, which expands the spray range of the chemical agents and allows the odor to fully contact the chemical agents, thus accelerating the odor treatment efficiency. Subsequently, under the action of the intermittent regulating component, the ball valve 20 on the outlet end 202 performs the opening and closing action, so that the treated tail gas and residual liquid in the treatment tank 2 flow into the collection device through the outlet end 202.

[0038] Preferably, a channel is formed on the ball valve 20, and controlling the rotation of the ball valve 20 can change the open and closed state of the air inlet 201 or the air outlet 202.

[0039] For further solutions to this utility model, please refer to [link / reference]. Figure 2 and Figure 3 The treatment tank 2 is detachably equipped with a tank cover 3. One end of the rotating nozzle 4 passes through the tank cover 3 and extends out of the tank cover 3. The tank cover 3 is provided with a transfer cylinder 8 arranged along the axial direction of the rotating nozzle 4. The annular cavity formed by the transfer cylinder 8 can communicate with the cylindrical cavity inside the rotating nozzle 4.

[0040] The drive assembly includes a first motor 5, and the output shaft of the first motor 5 is fixed to the rotating nozzle 4;

[0041] It also includes a pumping assembly 6 mounted on the mounting frame 1, the pumping assembly 6 having an output end and an input end, the output end being connected to the transfer cylinder 8 via a conduit 7.

[0042] Initially, the ball valve 20 on the air inlet 201 is open, and the odor is pumped into the treatment tank 2 through the air inlet 201. After a certain amount is pumped, the ball valve 20 rotates under the action of the intermittent regulating element, and the air inlet 201 is closed. At the same time as the odor is pumped, the first motor 5 and the pumping assembly 6 are started to work, so that specific chemical agents are pumped into the rotary nozzle 4. At the same time, the rotary nozzle 4 rotates, and through the centrifugal action and reaction force of the rotary nozzle 4, the sprayed chemical agents can be more evenly distributed in the treatment tank 2, thereby increasing the contact area and contact time between the odor molecules and the chemical agents, and improving the adsorption and decomposition efficiency of the odor molecules.

[0043] Before the gas outlet 202 is turned on, the first motor 5 and the pumping assembly 6 stop working to prevent the chemical agents that have not adsorbed the odor from being discharged outside the treatment tank 2 with the residual gas.

[0044] For further solutions to this utility model, please refer to [link / reference]. Figure 4 and Figure 5 The intermittent adjustment component includes a grooved roller 11 rotatably mounted on the mounting base 9, and the rotation of the grooved roller 11 is driven by a second motor 10 fixed on the mounting base 9. A movable sleeve 12 is slidably arranged along the axial direction of the grooved roller 11, and a first push rod 1202 and a second push rod 1203 are provided on the movable sleeve 12.

[0045] It also includes an elastic trigger element disposed on the mounting base 9, and the first push rod 1202 and the second push rod 1203 can intermittently push the elastic trigger element when they move.

[0046] The elastic trigger includes a support plate 13 mounted on the mounting base 9. A deflection rod 15 is rotatably disposed on one end of the support plate 13 away from the mounting base 9. A first limiting block 1301 and a second limiting block 1302 are symmetrically disposed at both ends of the support plate 13 to limit the deflection of the deflection rod 15.

[0047] It also includes a first spring 14, one end of which is hinged to the support plate 13 and the other end of which is hinged to the deflection rod 15.

[0048] Preferably, the inner wall of the movable sleeve 12 is provided with rolling balls 1201, and the grooved roller 11 is provided with a sliding groove 1101 that slides with the balls 1201. With the cooperation of the balls 1201 and the sliding groove 1101, when the grooved roller 11 rotates, the movable sleeve 12 reciprocates linearly along the axial direction of the grooved roller 11. During this process, the balls 1201 always move within the sliding groove 1101.

[0049] In the initial state, the first spring 14 is in a stretched state. At this time, the first spring 14 tends to rotate the deflection rod 15 toward the first limiting block 1301. Under the restriction of the first limiting block 1301, the deflection rod 15 can only rotate toward the second limiting block 1302. When the deflection rod 15 deflects toward the second limiting block 1302 under the compression of the first push rod 1202, the stretch of the first spring 14 increases. When the deflection rod 15 deflects to the equilibrium position with the support plate 13, the stretch of the first spring 14 increases.

[0050] Specifically, when the second motor 10 starts working, the air inlet 201 is in the open / closed state, and the air outlet 202 is in the closed state. The output shaft of the second motor 10 is fixed to the grooved roller 11, so that when the output shaft rotates, it drives the grooved roller 11 to rotate synchronously. When the grooved roller 11 rotates, the movable sleeve 12 reciprocates linearly along the axial direction of the grooved roller 11. When the movable sleeve 12 starts to move, the first push rod 1202 on it is not in contact with the deflection rod 15. The first push rod 1202 moves a certain distance. Then it comes into contact with the deflection rod 15. At this time, the pressure generated by the first push rod 1202 on the deflection rod 15 is greater than the elastic force of the first spring 14, causing the deflection rod 15 to rotate. When the deflection rod 15 deflects past the balance position with the support plate 13, under the action of the first spring 14, the deflection rod 15 quickly deflects towards the direction of the second limit block 1302, and during the deflection process, it squeezes the elastic telescopic member to drive the ball valve 20 to rotate. At this time, the ball valve 20 on the air inlet 201 is in the closed state.

[0051] For further solutions to this utility model, please refer to [link / reference]. Figure 5 When the deflection rod 15 deflects to the balance position of the support plate 13, it can squeeze the elastic telescopic member set on the mounting frame 1.

[0052] The ball valve 20 is fixedly connected to a push plate 19 arranged in a U-shape.

[0053] The elastic telescopic component includes a plug-in tube 16 disposed on the mounting frame 1, and a pressing rod 17 is slidably disposed inside the plug-in tube 16. Both ends of the pressing rod 17 pass through the plug-in tube 16, and one end of the pressing rod 17 is hinged to the push plate 19.

[0054] It also includes a second spring 18, which is disposed inside the plug tube 16. One end of the second spring 18 abuts against the inner end of the plug tube 16, and the other end abuts against the compression rod 17.

[0055] After the deflection rod 15 deflects past the balance position with the support plate 13, the continued deflection of the deflection rod 15 can squeeze the extrusion rod 17, causing the extrusion rod 17 to squeeze the second spring 18 again. The second spring 18 stores elastic potential energy. At this time, the extrusion rod 17 squeezes the push plate 19, causing the push plate 19 to drive the ball valve 20 to rotate, thereby achieving the closed state of the air inlet 201. When the movable sleeve 12 moves from the end of the stroke to the end of the stroke, the opening and closing state of the air inlet 201 changes from open to closed to closed, while the opening and closing state of the opposite air outlet 202 changes from closed to closed to open. This ensures that the odor pumped into the treatment tank can fully contact and adsorb the chemical agent before being discharged to the outside, thereby improving the adsorption and decomposition efficiency of odor molecules.

[0056] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0057] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
