Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a deodorization device for a wastewater treatment plant. Background Technology

[0002] The deodorization equipment in wastewater treatment plants includes biological filter deodorization devices, activated carbon deodorization devices, ozone deodorization devices, and ultraviolet deodorization devices. Among them, the biological filter deodorization device utilizes the metabolic action of microorganisms to decompose the organic matter in malodorous gases into harmless substances.

[0003] In practical applications, when the concentration of nutrients such as carbon, nitrogen, or phosphorus sources in the odorous gas is too high, providing excessive nutrients for microorganisms, it will promote the rapid growth and reproduction of microorganisms, ultimately leading to the continuous thickening of the biofilm. An excessively thick biofilm not only clogs the packing material, causing greater resistance to the gas as it passes through the equipment and affecting treatment efficiency, but also reduces the effective contact area between the gas and the packing material, directly impacting the gas purification effect.

[0004] To avoid the aforementioned situations and ensure effective odor treatment, high-pressure water or airflow is typically used to backwash the packing layer to remove the aged biofilm and maintain normal equipment operation. However, while effective, this method may cause some damage to the packing material. For example, with plastic packing, it may cause the packing to break or the pore structure to collapse, thus affecting the long-term stability and treatment efficiency of the equipment.

[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a deodorization device for wastewater treatment plants. Utility Model Content

[0006] The purpose of this utility model is to provide a deodorization device for a sewage treatment plant, which can solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A wastewater treatment plant deodorization device includes a biological deodorization device. The biological deodorization device is equipped with several sets of biofilm packing materials and a cleaning mechanism. The cleaning mechanism includes two sets of first support plates, which are located on the upper and lower sides of the biofilm packing materials, respectively. Each set of first support plates has a blade matching the shape of the biofilm packing material on the side closest to the biofilm packing material. A drive assembly for moving the first support plates is installed on the top of the biological deodorization device.

[0009] In one or more embodiments of the present invention, the drive assembly includes a positive and negative threaded rod, which is rotatably connected to the top of the biological deodorization device, and two sets of the first support plates are respectively threaded to the positive and negative threaded ends of the positive and negative threaded rod.

[0010] In one or more embodiments of this utility model, sliders are installed at both ends of the first support plate, and the inner wall of the biological deodorization device is provided with a groove that matches the slider.

[0011] In one or more embodiments of this utility model, the sidewall of the biological deodorization device is equipped with a viewing window that matches the drive assembly.

[0012] In one or more embodiments of this utility model, the first support plate is provided with a through hole that matches the shape of the blade, and the top of the biological deodorization device is equipped with an anti-clogging component that matches the through hole.

[0013] In one or more embodiments of this utility model, the anti-clogging component includes a second support plate, a plurality of push rods matching the through holes are installed on the side of the second support plate near the film packing, and an anti-drop handle is installed on the top of the second support plate.

[0014] In one or more embodiments of this utility model, the anti-fall handle includes a hinge block, the hinge block is installed on the top of the second support plate, the hinge block is slidably connected to the top of the biological deodorization device, a locking block is installed on the top of the hinge block, a handle is installed on the outside of the locking block, and a locking groove matching the locking block is opened on the outer wall of the handle.

[0015] In one or more embodiments of this utility model, the push rod is a glass rod with a smooth outer wall.

[0016] In one or more embodiments of this utility model, a filter plate matching the cleaning mechanism is installed below the biofilm packing.

[0017] In one or more embodiments of this utility model, a collection cone matching the anti-clogging component is installed on the filter plate, and a plurality of protrusions are installed on the outer wall of the collection cone.

[0018] Compared with the prior art, the deodorization equipment for a sewage treatment plant of this utility model can minimize damage to the packing material when the biofilm inside the equipment is too thick, causing blockage of the packing material, affecting the treatment efficiency and reducing the effective contact area between the gas and the packing material, thus affecting the gas purification effect.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figure 1 As shown in the figure, a wastewater treatment plant deodorization device according to one embodiment of the present invention includes a biological deodorization device 1. The biological deodorization device 1 generally includes an air inlet, an air outlet, and several sets of biofilm packing materials 101 installed inside the biological deodorization device 1. The wastewater treatment plant collects odorous gas through a closed pipe or gas collection hood and performs operations such as dust removal and humidification. The odorous gas is allowed to enter the biological deodorization device 1 through the air inlet. The odorous gas passes through microorganisms such as thiobacilli and nitrifying bacteria attached to the surface of the biofilm packing materials 101, which convert hydrogen sulfide, ammonia, etc., into carbon dioxide, water, and inorganic salts. The purified gas is then discharged at the air outlet after being tested and found to meet the standards.

[0030] like Figure 2 As shown, the biological deodorization equipment 1 is equipped with a cleaning mechanism. When the biofilm on the biofilm packing 101 is too thick and blocks the packing, affecting the contact between microorganisms and odorous gases, resulting in odorous gases in the exhaust gas, the user can use the cleaning mechanism to remove the excessively thick microbial film on the biofilm packing 101. This avoids the excessively thick biofilm from blocking the packing, which would cause the gas to encounter greater resistance when passing through the equipment, affecting the treatment efficiency. At the same time, it also avoids the excessively thick microbial film from reducing the effective contact area between the gas and the packing, thereby ensuring the deodorization effect.

[0031] like Figure 3 As shown, the cleaning mechanism includes two sets of first support plates 201, located on the upper and lower sides of the biofilm packing 101, respectively. Each set of first support plates 201 has a blade 202, matching the shape of the biofilm packing 101, installed on the side closest to the biofilm packing 101. A drive assembly for moving the first support plates 201 is installed on the top of the biological deodorization device 1. During the process of the drive assembly bringing the two sets of first support plates 201 closer together until the blades 202 come into contact, the blades 202 remove excess microorganisms from the surface of the biofilm packing 101.

[0032] Since the attachment and growth of microorganisms on the outer wall of the packing material are affected by various factors, the common biofilm thickness is 10-30 micrometers. Therefore, the distance between the blade 202 and the biofilm-attached packing material 101 is 10-30 micrometers.

[0033] like Figure 3 As shown, the drive assembly includes several sets of positive and negative threaded rods 204. Each positive and negative threaded rod 204 has threads with opposite directions at both ends. The positive and negative threaded rods 204 are rotatably connected to the top of the biological deodorization device 1 via bearings. Two sets of first support plates 201 are threadedly connected to the positive and negative threaded ends of the positive and negative threaded rods 204, respectively. During the rotation of the positive and negative threaded rods 204 in place, the two sets of first support plates 201 threadedly connected to the positive and negative threaded ends of the positive and negative threaded rods 204 can move along the outer wall of the positive and negative threaded rods 204, thereby driving the two sets of first support plates 201.

[0034] like Figure 4 As shown, sliders 2011 are installed at both ends of the first support plate 201, and the inner wall of the biological deodorization device 1 is provided with a groove 102 that matches the sliders 2011. The grooves 102 and sliders 2011 are used to limit the movement of the two sets of first support plates 201, so as to ensure that the two sets of first support plates 201 move stably in the vertical direction, moving closer to and away from the biofilm packing 101.

[0035] like Figure 1 As shown, the biological deodorization device 1 has a viewing window 103 installed on its side wall, which matches the drive assembly. The user can observe the positional relationship between the blade 202 and the biofilm packing 101 and the biofilm condition through the viewing window 103, so as to respond in a timely manner.

[0036] like Figure 5 As shown, the first support plate 201 has a through hole 203 that matches the shape of the blade 202, and the top of the biological deodorization device 1 is equipped with an anti-clogging component that matches the through hole 203. Excess microorganisms that are cut off leave the blade 202 through the through hole 203. The anti-clogging component is used to remove excess microorganisms from the blade 202 and the through hole 203, so as to avoid clogging of the blade 202 and the through hole 203 as much as possible, which would affect the next cutting.

[0037] like Figures 5-6 As shown, the anti-clogging component includes a second support plate 301. Several push rods 302, matching the through holes 203, are installed on the side of the second support plate 301 near the biofilm packing 101. A drop-proof handle is installed on the top of the second support plate 301. The user uses the drop-proof handle to move the second support plate 301 and the push rods 302 towards the through holes 203. When the push rods 302 move into the through holes 203, they push out excess microorganisms accumulated within the through holes 203.

[0038] like Figure 6 As shown, the anti-fall handle includes a hinge block 303, which is installed on the top of the second support plate 301. The hinge block 303 is slidably connected to the top of the biological deodorization device 1. A locking block 304 is installed on the top of the hinge block 303. A handle 305 is hinged to the outside of the locking block 304. A locking groove 3051 matching the locking block 304 is opened on the outer wall of the handle 305.

[0039] like Figure 6 As shown, when the user needs to move the anti-blocking component to clean the through hole 203, pull the handle 305 to the right. When the locking block 304 is at the leftmost end of the locking groove 3051, raise the handle 305 to control the anti-blocking component to move downward. When the user has finished cleaning and needs to fix the anti-blocking component, swing the handle 305 left and right to a horizontal position, and pull the handle 305 until the locking block 304 is in the middle of the locking groove 3051 to fix the anti-blocking component.

[0040] like Figure 5As shown, push rod 302 is a glass rod with a smooth outer wall. The smooth outer wall of the glass rod can, to some extent, prevent excess microorganisms from adhering to the outer wall of push rod 302.

[0041] like Figure 5 As shown, a filter plate 401 matching the cleaning mechanism is installed below the biofilm packing 101. The filter plate 401 is used to catch excess microorganisms removed by the cleaning mechanism, making it easier for the user to remove the collected excess microorganisms.

[0042] like Figure 5 As shown, a collection cone 402 matching the anti-clogging component is installed on the filter plate 401, and several sets of protrusions 403 are installed on the outer wall of the collection cone 402. Microorganisms pushed down by the anti-clogging component adhere to the surface of the collection cone 402, minimizing the risk of falling microorganisms clogging the filter plate 401 and affecting the normal purification of odorous gas to the biofilm packing 101. The protrusions 403 help to hang excess microorganisms on the collection cone 402.

[0043] During use, when the biofilm on the outer wall of the biofilm packing 101 is too thick, in order to maintain the normal operation of the biological deodorization equipment 1, it is necessary to remove the excess biofilm inside the biofilm packing 101. The user rotates the positive and negative threaded rods 204 to drive the two sets of first support plates 201 located on both sides of the biofilm packing 101 to approach the biofilm packing 101, until the cutter 202 cuts off the excessively thick biofilm on the outer wall of the biofilm packing 101. At the same time, since there is a gap between the cutter 202 and the inner wall of the packing in the biofilm packing 101, the microorganisms in the gap can be preserved during the cutting process of the cutter 202, ensuring that the microorganisms deodorize normally while avoiding damage to the packing in the biofilm packing 101 to a certain extent.

[0044] The removed biofilm partially falls off and partially remains in the through hole 203. When the cutter 202 and the through hole 203 are blocked by excess biofilm, the user uses the anti-drop handle to move the second support plate 301 toward the cutter 202 until the push rod 302 is located in the cutter 202 and the through hole 203, thus pushing out the blocked biofilm.

[0045] The biofilm falls onto the collection cone 402 on the surface of the filter plate 401 and is collected, which helps to prevent the filter plate 401 from clogging and ensures that the odor from the filter plate 401 to the biofilm packing 101 flows normally.

[0046] 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.

[0047] 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.
