Description

A fiberglass biological filter deodorization device Technical Field

[0001] This invention relates to the field of fiberglass equipment technology, and in particular to a fiberglass biofilter deodorization device. Background Technology

[0002] Fiberglass reinforced plastic (FRP), also known as fiber-reinforced plastic (GFRP), generally refers to unsaturated polyester, epoxy resin, and phenolic resin matrices reinforced with glass fibers. Reinforced plastics using glass fibers or their products as reinforcing materials are called glass fiber reinforced plastics, or simply fiberglass, and are different from tempered glass. Due to the different types of resins used, there are polyester fiberglass, epoxy fiberglass, and phenolic fiberglass. It is lightweight yet hard, non-conductive, has stable properties, high mechanical strength, low recyclability, and is corrosion-resistant. It can replace steel in the manufacture of machine parts and the outer shells of automobiles and ships, thus its applications are quite widespread.

[0003] Currently, biological deodorization filter beds on the market mainly fall into two categories: biological filter beds and biological soil filter beds.

[0004] Biological filter deodorization technology is a treatment system that uses lightly acclimated microorganisms placed on a specially prepared active biological medium. Through the adsorption, absorption, and degradation of malodorous substances by these microorganisms, the substances are converted into non-toxic, simple inorganic substances such as CO2, H2O, H2SO4, and N2O3. The biological active medium has a large porosity and surface area, and is maintained at a certain humidity through controlled circulating spraying. The medium carries a large number of acclimated microorganisms, including fungi and bacteria, forming a biochemical synthesis. As the odor passes through the biological active medium bed, it comes into contact with the water in the medium, resulting in adsorption and dissolution into the water film on the medium. Under suitable temperature and humidity conditions, the microorganisms in the medium metabolize the components of the odor by adsorbing and absorbing them. During this metabolism, the malodorous components are decomposed by the microorganisms as nutrients, producing harmless substances such as CO2 and H2O, thereby removing the pollutants.

[0005] Biological filter deodorization devices are currently the most researched, technologically mature, and commonly used method for treating odorous gases. The process involves the gas containing odorous substances undergoing pretreatment processes such as dust removal, humidification, or cooling before passing through the filter bed from bottom to top. As it passes through the filter layer, the odorous substances are transferred from the gas phase to the water-microorganism mixed phase (biological layer), where they are decomposed by the metabolic activity of microorganisms attached to and growing on the filter media. This method primarily utilizes the biochemical action of microorganisms to decompose pollutants and transform them into harmless substances. Microorganisms use organic matter as a substrate for their growth and reproduction, and through different transformation pathways, they oxidize and decompose large molecules or complex organic matter into simple inorganic substances such as water and carbon dioxide through dissimilatory processes. Simultaneously, through assimilation and the energy generated during dissimilatory processes, microorganisms grow and reproduce, creating favorable conditions for further enhancing their ability to treat organic matter.

[0006] Chinese patent CN110624393A discloses a multi-stage deodorization device and method for a biological filter. The biological filter is equipped with a spray device at the top and is divided into a pre-washing tank and a biological tank by a partition. Pre-washing filter layers and biological filter layers are respectively installed on filter layer support plates in the pre-washing tank and the biological tank. The biological filter layer consists of a biological matrix filled with microorganisms and an inorganic mixture of fillers. The microorganisms are a mixture of Bacillus and Agrobacterium, and the inorganic mixture is a mixture of sodium dihydrogen phosphate and disodium hydrogen phosphate. In the pre-washing tank, odorous gases are pre-washed and filtered, dissolving particles and ash in the odorous gases in water before entering the biological filter layer. The rapidly multiplying microorganisms on the biological matrix slowly release and adsorb and degrade odor-causing pollutants, converting them into carbon dioxide and water. The inorganic mixture adjusts the pH of the filler to maintain it at 6-8, preventing acidification of the biological filter layer. This provides an optimal environment for pollutant adsorption and microbial growth, resulting in purified gas discharge with a high removal rate and no secondary pollution.

[0007] The above technical solution has the following problems:

[0008] 1. Odor pretreatment mainly involves the use of a spray system, plastic granules, and an inner water tank to pretreat particulate matter and water-soluble gases. However, in this structure, some odor can still directly enter the biological tank through gaps, resulting in a generally poor gas-liquid mixing effect.

[0009] 2. The mixed materials in the biological tank are prone to caking after a period of use, and the resistance will gradually increase, requiring regular renovation. However, the maintenance and operation of the biological tank in this technical solution is difficult. Summary of the Invention

[0010] The purpose of this invention is to provide a fiberglass biological filter deodorization device that helps solve the problems of poor gas-liquid mixing effect and easy caking and maintenance difficulties in existing structures.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] A fiberglass biological filter deodorization device includes a fiberglass shell, inside which are arranged an upper and lower biological tank and a pre-washing tank.

[0013] The pre-washing tank is provided with an inlet and an outlet at both ends, and the inlet and outlet are connected by a circulation pipe. The inlet is also connected to an air inlet pipe. The odor enters the pre-washing tank through the air inlet pipe and the inlet. The pre-washing tank is filled with water covering the inlet. The pre-washing tank is also provided with a guide to slow down the gas flow speed on the inside of the inlet.

[0014] A connecting duct and a diversion chamber are provided between the biological tank and the pre-washing tank. The inlet end of the duct is located at the top of the outlet side of the pre-washing tank. The duct has an n-shaped channel structure and a first spray device is installed inside the duct. The diversion chamber is located at the bottom of the biological tank.

[0015] The biological tank is equipped with an inlet and an outlet. The biological tank is filled with a biological filter layer for cultivating bacteria to decompose odor components. A second spray device is provided on top of the biological filter layer. A bottom plate is provided at the bottom of the biological tank. Through holes that connect to the diversion chamber are evenly distributed on the bottom plate. A stirrer is provided inside the biological tank.

[0016] Based on the above technical solution, the water inlet end is provided with a Venturi tube structure, and the connection between the air inlet pipe and the water inlet end is located in the low-pressure region of the Venturi tube.

[0017] Based on the above technical solution, the guide component is a guide plate set on the top of the pre-washing tank. The bottom of the guide plate has an irregular concave-convex profile. The water in the pre-washing tank covers the concave-convex profile, and the odorous gas input by the air inlet pipe can flow along the concave-convex profile.

[0018] Based on the above technical solution, the top of the guide plate and the top of the pre-washing tank are connected by an elastic column, which can perform longitudinal elastic expansion and contraction, and the bottom of the elastic seat is connected to the top of the guide plate by a universal connection structure.

[0019] Based on the above technical solution, the guide component is a guide cylinder disposed inside the water inlet end. The guide cylinder is provided with guide blades of a spiral structure inside. The inlet and outlet ends of the guide cylinder are respectively facing the water inlet end of the circulation pipe and the input end of the air duct.

[0020] Based on the above technical solution, the air duct is equipped with a demister above the first spray device.

[0021] Based on the above technical solution, a sliding seat is provided on the outside of the demister, and a guide rod is provided on the inner wall of the air duct near the demister assembly area. The sliding seat is sleeved on the guide rod and can slide up and down.

[0022] Based on the above technical solution, an elastic element that abuts against the slide is sleeved on the guide rod, and the extension and retraction direction of the elastic element is longitudinal.

[0023] Based on the above technical solution, a blowing device is provided inside the diversion cavity.

[0024] Based on the above technical solution, a one-way valve is installed inside the air duct.

[0025] Based on the above technical solution, the guide component is a guide bend, with its two sides facing the water inlet of the circulation pipe and the input end of the air duct, respectively.

[0026] Based on the above technical solution, the air duct is equipped with a filter below the first spray device, and the filter is filled with plastic filler.

[0027] Based on the above technical solution, a drain outlet is provided at the bottom of the diversion cavity.

[0028] Compared with the prior art, the present invention has at least the following advantages:

[0029] 1. The present invention, by setting up a structure that allows the inlet of the air inlet pipe to directly enter the water inside the pre-wash tank, enables the odor to directly contact the water after exiting the pre-wash tank. Furthermore, through the slowing effect of the flow guide, the odor can fully contact the water in the pre-wash tank, resulting in sufficient gas-liquid mixing. This allows particulate impurities and water-soluble gases in the odor to fully adhere to and remain in the pre-wash tank.

[0030] 2. This invention, by installing a stirrer in the biological tank, enables the biological filter to be passively tumbled and stirred after long-term use, thereby effectively preventing hardening and allowing the organisms inside to maintain a suitable living environment for a long time.

[0031] 3. By setting up air ducts and diversion chambers, the present invention allows odorous gas to be further sprayed by the first spray device in the air duct after being filtered through the pre-washing tank. This step-by-step treatment helps to improve the gas purification effect. After being evenly diverted in the diversion chamber, the gas passes through the bottom plate and enters the biological tank. This diversion method can make full use of the biological filter layer in each area of ​​the biological tank, avoiding the differentiation of working areas due to position, and the uneven use of the biological filter layer, which would affect the purification and deodorization effect.

[0032] 4. The shell of this invention is made of fiberglass, which makes the structure stable and easy to process and assemble. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the present invention clearer, a detailed description is provided below in conjunction with the accompanying drawings and specific embodiments. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0044] Example 1:

[0045] As shown in Figure 1, this embodiment discloses a fiberglass biological filter deodorization device. The deodorization device includes a shell made of fiberglass, specifically a rectangular box structure. The shell is made of fiberglass material, which makes the structure stable, has a long service life, is flexible in processing, and is easy to assemble.

[0046] The shell contains a biological pool 6 and a pre-washing pool 1 arranged vertically.

[0047] The pre-washing tank 1 is specifically a tank structure located at the bottom of the shell. The pre-washing tank 1 is filled with water, and has an inlet end 21 and an outlet end 22 at both ends. The inlet end 21 and the outlet end 22 are connected by a circulation pipe. The circulation pipe is equipped with a water pump and a filter media device. The water pump is used to provide power for the circulation water path, and the filter media device is used to filter particulate matter or adsorb other substances in the water path.

[0048] The water inlet 21 is also connected to the air inlet pipe 3. The odor enters the pre-washing tank 1 through the air inlet pipe 3 and the water inlet 21. The water in the pre-washing tank 1 covers the position of the water inlet 21, so that the odor directly contacts the water after entering the pre-washing tank 1.

[0049] Specifically, the water inlet 21 is provided with a Venturi structure, and the connection between the air inlet pipe 3 and the water inlet 21 is located in the low-pressure area of ​​the Venturi. This helps the odor to enter the pre-washing tank 1 with the circulating water flow in the circulation pipe 2. In addition, a fan 31 is provided on the air inlet pipe 3. The fan 31 can provide additional power for the transport of odor, helping the odor to enter the pre-washing tank 1 smoothly and evenly.

[0050] In the specific implementation process, the odor enters the pre-washing tank 1 and comes into direct contact with the water. The particulate matter or dust mixed in the odor can be "captured" by the water, and some water-soluble gases in the odor will also dissolve in the water. Therefore, the pre-washing tank 1 can filter and pre-treat the odor.

[0051] Furthermore, to improve the gas-liquid mixing effect between odor and water, the pre-wash tank 1 is also equipped with a flow guide to slow down the gas flow rate on the inner side of the water inlet 21. In this embodiment, the flow guide is a flow guide plate 11 set on the top of the pre-wash tank 1, as shown in Figure 2. The bottom of the flow guide plate 11 has an irregular concave-convex contour 111. The water in the pre-wash tank 1 covers the concave-convex contour 111, and the odor input by the air inlet pipe 3 can flow along the concave-convex contour 111. Since the outer surface area of ​​the concave-convex contour 111 is large, it can travel a longer path when guiding the gas flow, thereby slowing down the flow of odor. This helps to increase the gas-liquid contact time and contact surface, and improve the gas-liquid mixing effect.

[0052] Furthermore, the top of the guide plate 11 is connected to the top of the pre-wash tank 1 via an elastic column 113. The elastic column 113 is a columnar structure made of rubber material with multiple variable diameter bodies stacked together, which can perform longitudinal elastic expansion and contraction. The bottom of the elastic seat is connected to the top of the guide plate 11 via a universal connection structure. The universal connection structure includes a connection hole 112 on the top surface of the guide plate 11. The connection hole 112 is a spherical hole. The bottom of the elastic column 113 is a spherical structure, which is embedded in the connection hole 112 and can rotate flexibly in the connection hole 112. The elastic columns 113 are evenly distributed on the guide plate 11. The top of the elastic column 113 is fixedly connected to the top plate of the pre-wash tank 1. The function of the elastic column 113 is to provide the guide plate 11 with flexible swinging ability. When the odor impacts the guide plate 11 from the bottom, the guide plate 11 will deform accordingly with the help of the elastic column 113 after receiving sufficient impact force, thereby buffering and absorbing the impact force, and thus helping the guide plate 11 to slow down the flow of odor.

[0053] A connecting duct 4 and a diversion chamber 5 are provided between the biological tank 6 and the pre-washing tank 1. The input end of the duct 4 is located at the top of the outlet end 22 of the pre-washing tank 1. The duct 4 has an n-shaped channel structure. The duct 4 is equipped with two first spray devices 41 spaced vertically and a demister 42 located above the first spray devices 41. The first spray devices 41 are used to spray the gas output from the pre-washing tank 1 again. The first spray devices 41 are equipped with multiple atomizing nozzles to spray the gas again with atomized water, ensuring that particulate matter or water-soluble gas components in the gas can be fully intercepted and filtered. The demister 42 is used to dehumidify the sprayed gas. On the one hand, the dehumidified gas will not liquefy on the side wall of the rear section of the duct 4, which can easily accumulate impurities over time and cause uncontrollable reactions that affect the overall environmental health of the biological tank 6. On the other hand, the dehumidified gas will not carry water after entering the biological tank 6, which can reduce the dynamic impact on the humidity in the biological tank 6, thereby better controlling the humidity inside the biological tank 6.

[0054] A one-way valve 43 is installed in the rear section of the air duct 4. The function of the one-way valve 43 is to effectively prevent gas backflow and ensure the stability of one-way gas delivery.

[0055] Furthermore, the diversion chamber 5 is located at the bottom of the biological tank 6, and its main function is to evenly disperse the gas before it enters the biological tank 6, which can make full use of each area of ​​the biological tank 6. A blowing device is provided at the front end of the diversion chamber 5. In this embodiment, the blowing device is a fan 51. The fan 51 can drive the gas inside the diversion chamber 5 to the rear, so that the gas can be evenly dispersed to each area of ​​the diversion chamber 5. The presence of the one-way valve 43 can prevent the gas from flowing back into the branch pipe under the drive of the fan 51, but instead ensure that it flows evenly to each area of ​​the diversion chamber 5. A drain outlet 52 is provided at the bottom of the rear end of the diversion chamber 5. Since the diversion chamber 5 is located at the bottom of the biological tank 6, when the humidity in the biological tank 6 is too high, liquefied water will fall into the diversion chamber 5, and the drain outlet 52 is used to discharge this liquid water.

[0056] The biological tank 6 is equipped with an inlet 63 and an outlet 64, which are used for the input and output of materials in the biofilter layer 61, respectively. The inlet 63 is also equipped with a ventilation structure for the emission of exhaust gas. The biological tank 6 is filled with a biofilter layer 61 for cultivating bacteria to decompose odor components. This is existing technology, and the specific structure and working principle of the structure during operation will not be described in detail here. The biological tank 6 is equipped with a second spray device 62 at the top of the biofilter layer 61. The second spray device 62 is used to control the humidity inside the biological tank 6, thereby ensuring suitable working conditions inside.

[0057] The bottom of the biological pool 6 is provided with a first bottom plate 66, on which through holes communicating with the diversion cavity 5 are evenly distributed. These through holes allow gas in the diversion cavity 5 to rise and enter the biological pool 6, and also allow water in the biological pool 6 to drain down into the diversion cavity 5. The through holes can be used with filter media.

[0058] Furthermore, the biological tank 6 is equipped with a stirrer 65. In this embodiment, the stirrer 65 is a spiral stirrer 65, which has spiral blades capable of rotating and agitating materials laterally. The stirrer 65 is connected to a drive motor (not shown in the figure) for periodically stirring the materials inside the biological tank 6 to prevent the materials from hardening and caking. It should be noted that the agitating end of the stirrer 65 faces the feed inlet 63, which helps to complete the material discharge using a mechanical structure, thereby reducing manual operation, lowering labor intensity, and improving work efficiency.

[0059] In the specific implementation process, the odor gas is output to the pre-washing tank 1 through the inlet pipe 3. The pre-washing tank 1 pre-treats the odor gas, so that particulate matter or water-soluble components are filtered out. Then, the gas output from the pre-washing tank 1 is further sprayed by the first spray device 41 in the air pipe 4 and dehumidified by the demister 42. The dehumidified gas is evenly distributed in the diversion chamber 5 and then enters the biological tank 6 from bottom to top. It interacts with the biological filter layer 61 in the biological tank 6, and the odor components are decomposed and absorbed. The deodorized and purified tail gas is output through the feed inlet 63.

[0060] Example 2:

[0061] Based on Embodiment 1 and referring to Figure 3, in order to provide additional power to the demister 42, a slide 422 is provided on the outer side of the demister 42 in this embodiment. A movable groove 44 is provided on the inner side wall of the air duct 4 near the assembly area of ​​the demister 42. A vertical guide rod 45 is provided in the movable groove 44. The slide 422 is sleeved on the guide rod 45 and can slide up and down. Since the corrugated plate 421 of the demister 42 itself can play a certain blocking effect, when the airflow entering the air duct 4 is large, the airflow can lift the demister 42 upward. The demister 42 slides upward along the guide rod 45. Using its own weight, it will apply a downward pressure to the airflow, which will converge on the original resistance. Therefore, the resistance received by the airflow increases, so the correspondence between the demister 42 and the airflow size can complete the buffer speed adjustment effect during the automatic lifting process, making the airflow delivery speed more uniform and smooth.

[0062] Furthermore, in order to improve the sensitivity of the demister 42 to the change in airflow size, an elastic element is fitted on the guide rod 45 to abut against the slide 422. The elastic element is arranged longitudinally in the direction of extension and retraction. In this embodiment, the elastic element is a spring 46 located at the bottom of the slide 422. An adjusting screw is also provided on the guide rod 45 at the bottom of the spring 46. The compression degree of the spring 46 is controlled by adjusting the assembly position of the adjusting bolt 47. After assembly, the spring 46 can bear part of the weight of the demister 42 and provide better elastic support, making the up and down movement of the demister 42 more sensitive and obvious.

[0063] Furthermore, the bottom of the demister 42 is provided with a baffle 423, which can reduce the entry of mist-carrying gas into the movable groove 44 and reduce the negative impact on the guide rod 45 and spring 46. A sealing ring 424 is also provided between the baffle 423 and the inner wall of the air duct 4 to further improve the sealing effect.

[0064] Example 3:

[0065] Based on Example 1, and referring to Figure 4, the difference in this example is that the pre-wash tank 1 is provided with two circulation pipes. The water inlet 21 of the two circulation pipes is located on both sides of the pre-wash tank 1, and each side is connected to an air inlet pipe 4. The two sides are also provided with corresponding water outlets 22 (not shown in the figure). In this example, there are two guide plates 11, which are symmetrically arranged on the upper and lower sides of the pre-wash tank 1. This structure helps to improve the air intake flow. The positions of the water inlet 21 on both sides are staggered, which allows the internal water to improve the internal circulation effect under the influence of the water flow at the water inlet 21. This circulation effect helps to improve the internal gas-liquid mixing rate, achieving an effect similar to that of a dissolving tank.

[0066] Example 4:

[0067] Based on Example 1, and as shown in Figure 5, the bottom of the biological tank 6 is provided with a second bottom plate 67 with an inclined structure, and the bottom of the diversion cavity 5 is an inclined slope 53. The lower side of the slope 53 is located on the side of the drain outlet 52. The slope 53 and the second bottom plate 67 form a transverse V-shaped cavity. That is to say, the higher side of the second bottom plate 67 is far away from the air inlet side of the diversion cavity 5, which helps the gas to flow to the rear, thereby improving the diversion effect of the diversion cavity 5, while the slope 53 is beneficial to the discharge of accumulated water.

[0068] Example 5:

[0069] Based on Embodiment 1 and referring to Figure 6, the difference in this embodiment is that the guide element is a guide cylinder 12 disposed inside the water inlet 21, with multiple guide cylinders 12 arranged side by side. The guide cylinder 12 has spiral guide vanes 121 inside, and its inlet and outlet ends face the water inlet 21 of the circulation pipe and the input end of the air duct 4, respectively. During operation, the circulating water carries the odor into the guide cylinder 12, and the guide vanes 121 provide spiral guidance, increasing the flow rate and rotational changes, resulting in more efficient and thorough gas-liquid mixing.

[0070] Example 6:

[0071] Based on Embodiment 5, and as shown in Figure 7, the difference in this embodiment is that the guide component is a guide bend 13, with the two sides of the guide bend 13 facing the water inlet 21 of the circulation pipe and the input end of the air duct 4, respectively. It should be noted that the guide bend 13 can extend the flow path of the circulating water, thereby increasing the gas-liquid contact time and improving the gas-liquid mixing effect. The guide bend 13 in this embodiment is also equipped with a spiral structure guide vane 121 inside.

[0072] Example 7:

[0073] Based on Embodiment 1, the air duct 4 is provided with a filter 48 below the first spray device 41. The filter 48 is filled with plastic filler, which helps to disperse the airflow and prevent the airflow from clumping. This can help the first spray device 41 improve the spray purification effect and also help to stabilize the airflow.

[0074] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
