Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology; more specifically, it relates to a waste gas treatment device. Background Technology

[0002] Wastewater and waste gas treatment equipment is an important piece of equipment for environmental protection. It is used to reduce the emission of pollutants generated in industrial production, urban life and other activities. Wastewater and waste gas treatment equipment is the core facility of modern environmental protection system and is widely used in chemical, pharmaceutical and energy industries, as well as in urban sewage treatment plants, waste incineration plants and other fields.

[0003] Currently, existing waste gas treatment devices often suffer from dust accumulation due to the presence of impurities and dust in the waste gas. Most devices rely on spraying to reduce these contaminants. Furthermore, these devices are often inconvenient for wastewater recycling and filtration, resulting in significant water consumption and reduced practicality. Additionally, the filters in most existing devices are fixed inside the unit, making replacement difficult as their lifespan nears completion, further complicating the device's usability. Therefore, a new waste gas treatment device is urgently needed to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waste gas treatment device to solve the problems existing in the background art.

An installation structure and a replacement structure are provided inside the support column, and an adsorption structure is provided at the upper end of the support column.

[0007] The dust suppression structure includes a water pump, which is installed on the bottom surface inside the water storage tank.

[0008] The mounting structure includes a first mounting opening, which is located inside the lower outer surface of one side of the support column.

[0009] The replacement structure includes a second mounting port, which is located inside the upper outer surface of one side of the support column.

[0010] The adsorption structure includes an insertion groove, which is located inside the outer surface of the upper end of the support column.

[0011] Preferably, the dust suppression structure further includes a water pipe, one end of which is connected to the output end of a water pump, and the other end of which is connected to a diversion pipe. The diversion pipe is installed on the inner wall surface of the support column, and the inner surface of the diversion pipe is connected to a nozzle, and multiple nozzles are provided. A sewage filter plate is inserted inside the outer surface of one side of the water storage tank, and one end of the sewage filter plate is made of rubber. This design prevents the stored water from flowing out from the installation point of the sewage filter plate when the sewage filter plate is inserted inside the outer surface of one side of the water storage tank.

[0012] Preferably, the mounting structure further includes a first positioning hole, and there are two sets of the first positioning holes. The two sets of the first positioning holes are respectively opened inside the inner wall surface of the upper and lower ends of the first mounting port. The first mounting port is filled with filler, and the inner surface of the upper and lower ends of one end of the filler is provided with a first movable groove. The first movable groove is provided with a first spring, and a first push plate is engaged and slidably connected inside the first movable groove. The outer dimension of one end of the first push plate is adapted to the inner dimension of the first positioning hole. The two ends of the first spring abut against the surface of one side of the first push plate and the inner wall surface of one side of the first movable groove, respectively. The outer surface of the other end of the filler is fixedly connected with an insert block. The inner wall surface of one side of the first mounting port is provided with a slot, and the inner dimension of the slot is adapted to the outer dimension of the insert block. This design makes the filler more stable when installed inside the first mounting port.

[0013] Preferably, the replacement structure further includes a second positioning hole, which is located inside the inner wall surface of the lower end of the second mounting port. A support frame is inserted inside the second mounting port, and a mounting groove is provided inside the support frame. Positioning rods are fixedly connected to the bottom surfaces of both ends of the mounting groove, and nuts are threaded onto the outer surfaces of the upper ends of the positioning rods. A first filter screen, a second filter screen, and a third filter screen are fitted onto the outer surfaces of the two sets of mounting grooves. A second movable groove is provided inside the outer surface of one end of the support frame, and a second spring is provided inside the second movable groove. A second push plate is engaged inside the second movable groove. This design allows the second push plate to move up or down inside the second movable groove.

[0014] Preferably, the first filter screen is made of silver ions, the second filter screen is made of activated carbon, and the third filter screen is made of meltblown polyester. The two ends of the second spring abut against the surface of one side of the second push plate and the inner wall surface of one side of the second movable groove, respectively.

The outer diameter of the rotating adsorption layer and the inner diameter of the dividing cover are adapted to each other. The material of the rotating adsorption layer is silicone. This design makes the dividing cover more stable when it is fitted onto the outer surface of the rotating adsorption layer.

[0016] The technical effects and advantages of this utility model are as follows: This utility model draws water stored in the water tank by starting a water pump, and sprays the inside of the support column through multiple sets of nozzles, so that the dust and impurities in the exhaust gas are neutralized by the water flow and fall into the inside of the water tank. The wastewater is filtered by the sewage filter plate and falls to the bottom of the water tank for reuse, which improves the practicality of the device to a certain extent.

[0017] By pushing the second push plate upwards, the lower end of the second push plate is disengaged from the interior of the second positioning hole. At this point, the support frame can be pulled outwards. Then, the nut can be rotated to disengage from the outer surface of the positioning rod. Subsequently, the first filter screen, the second filter screen, and the third filter screen can be removed from the interior of the support frame in sequence to facilitate the replacement of the first filter screen, the second filter screen, and the third filter screen. This improves the practicality of the device to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The environmental protection equipment involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] like Figures 1-5 As shown, this embodiment proposes a waste gas treatment device, including:

[0027] Water storage tank 1, with a support column 2 connected to the outer surface of the upper end of the water storage tank 1, and a dust suppression structure 3 is provided inside the water storage tank 1 and the support column 2, and an exhaust gas inlet 4 is fixedly connected to the outer surface of the lower end of the support column 2, with an installation structure 5 and a replacement structure 6 provided inside the support column 2, and an adsorption structure 7 is provided at the upper end of the support column 2.

[0028] The dust suppression structure 3 includes a water pump 31, which is installed on the bottom surface inside the water storage tank 1. The dust suppression structure 3 also includes a water pipe 32, one end of which is connected to the output end of the water pump 31, and the other end of which is connected to a diversion pipe 33. The diversion pipe 33 is installed on the inner wall surface of the support column 2, and the inner surface of the diversion pipe 33 is connected to a nozzle 34. Multiple nozzles 34 are provided. A sewage filter plate 35 is inserted inside the outer surface of one side of the water storage tank 1. One end of the sewage filter plate 35 is made of rubber. This design, through the sealing and elasticity of the rubber material at one end of the sewage filter plate 35, makes the sewage filter plate 35 more stable when inserted inside the side of the water storage tank 1, and can seal the inside of the water storage tank 1.

[0029] The mounting structure 5 includes a first mounting opening 51, which is located inside the lower outer surface of one side of the support column 2. The mounting structure 5 also includes two sets of first positioning holes 52, located inside the upper and lower inner walls of the first mounting opening 51. A filler 53 is inserted into the first mounting opening 51, and a first movable groove 54 is formed inside the upper and lower outer surfaces of one end of the filler 53. A first spring 55 is located inside the first movable groove 54, and a first push plate 56 is slidably connected to it. The external dimensions of one end of the first push plate 56 are adapted to the internal dimensions of the first positioning hole 52. The first spring 55... The two ends respectively abut against the surface of one side of the first push plate 56 and the inner wall surface of one side of the first movable groove 54. The outer surface of the other end of the filler 53 is fixedly connected with an insert block. The inner wall surface of one side of the first mounting port 51 is provided with a slot, and the internal size of the slot is adapted to the external size of the insert block. This design makes it more stable when one end of the first push plate 56 is inserted into the first positioning hole 52. This design also allows the first push plate 56 to return to its original position under the elasticity of the first spring 55 after moving inside the first movable groove 54. At the same time, this design makes the filler 53 more stable when inserted into the first mounting port 51 and prevents the filler 53 from falling out inside the support column 2.

[0030] Example 2

[0031] like Figures 4-5 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0032] The replacement structure 6 includes a second mounting port 61, which is located inside the upper outer surface of one side of the support column 2. The replacement structure 6 also includes a second positioning hole 62, located inside the lower inner wall surface of the second mounting port 61. A support frame 63 is inserted into the second mounting port 61, and a mounting groove 64 is formed inside the support frame 63. Positioning rods 65 are fixedly connected to the bottom surfaces at both ends of the mounting groove 64, and nuts 66 are threaded onto the upper outer surface of the positioning rods 65. A first filter screen 67, a second filter screen 68, and a third filter screen 69 are fitted onto the outer surfaces of the two sets of mounting grooves 64. A second movable groove 610 is formed inside the outer surface of one end of the support frame 63, and a second spring 611 is provided inside the second movable groove 610. The internally engaged design includes a second push plate 612, a first filter 67 made of silver ions, a second filter 68 made of activated carbon, and a third filter 69 made of meltblown polyester. The two ends of a second spring 611 abut against the surface of one side of the second push plate 612 and the inner wall surface of one side of the second movable groove 610, respectively. The external dimensions of the lower end of the second push plate 612 are matched with the internal dimensions of the second positioning hole 62. This design reduces microorganisms and bacteria in the exhaust air due to the antibacterial and long-lasting properties of the first filter 67 material. Furthermore, the design adsorbs odors in the exhaust air due to the strong adsorption and stability of the second filter 68 material. Simultaneously, the design intercepts residual dust in the exhaust gas due to the high filtration efficiency and low ground resistance of the third filter 69 material.

[0033] The two ends of the second spring 611 abut against the surface of one side of the second push plate 612 and the inner wall surface of one side of the second movable groove 610, respectively. The outer dimensions of the lower end of the second push plate 612 are matched with the inner dimensions of the second positioning hole 62. This design allows the second push plate 612 to return to its original position by its own elasticity after moving inside the second movable groove 610, and makes the second push plate 612 more stable when inserted into the second positioning hole 62.

[0034] The adsorption structure 7 includes an insertion groove 71, which is located inside the outer surface of the upper end of the support column 2. The adsorption structure 7 also includes an insertion groove 72, located inside the inner wall surface of the insertion groove 71. An insertion block 73 is inserted into the insertion groove 72, and a rotating adsorption layer 74 is fixedly connected to the outer surface of the upper end of the insertion block 73. A dividing cover 75 is inserted into the insertion groove 71, and an air outlet is located at the top of the dividing cover 75. A rubber ring is fixedly connected to the bottom of the dividing cover 75. The internal dimensions of the insertion groove 71 and the external dimensions of the rubber ring are compatible. The outer diameter of the rotating adsorption layer 74 and the outer diameter of the dividing cover 75 are also compatible. With a matching inner diameter, the rotating adsorption layer 74 is made of silicone. This design utilizes the sealing and elasticity of the rubber ring to seal the inside of the support column 2 when the dividing cover 75 is inserted into the insertion slot 71. This design also makes the dividing cover 75 more stable when inserted into the insertion slot 71. When the dividing cover 75 is fitted onto the outer surface of the rotating adsorption layer 74, the gas exhaust distance is increased, which facilitates the re-adsorption of the exhaust gas. At the same time, the design utilizes the porosity and reversibility of the rotating adsorption layer 74 to allow it to adsorb more moisture and be reused.

[0035] Working Principle: When using the device, first place it in a suitable position. Connect the exhaust gas pipe and the exhaust gas inlet 4 so that the exhaust gas can directly enter the interior of the support column 2. The exhaust gas is then evenly dispersed by the packing material 53. At this time, the water pump 31 can be started to draw the stored water from the water storage tank 1. The stored water enters the interior of the diversion pipe 33 through the water pipe 32 and enters the interior of the support column 2 through multiple sets of nozzles 34 to spray the exhaust gas. Impurities and dust in the exhaust gas fall onto the outer surface of the packing material 53, and wastewater falls onto the outer surface of the upper end of the sewage filter plate 35 for filtration. The filtered water falls into the water storage tank 1 for collection and reuse. The wastewater filter plate 35 can be pulled out for cleaning or replacement as needed. At this time, the gas, after initial dust reduction, enters the installation tank 64 and passes sequentially through the third filter screen 69, the second filter screen 68, and the first filter screen 67, where odors, impurities, and harmful substances in the gas are adsorbed. The gas then rises into the rotating adsorption layer 74 and the dividing hood 75. Here, the rotating adsorption layer 74, with its own material adsorption properties, further adsorbs moisture from the gas, thus filtration... The air afterward is relatively dry and is discharged outward through the air outlet. When the device is finished, and the installation structure 5 needs to be replaced, the two sets of first push plates 56 can be pinched inward to disengage one end of the first push plate 56 from the inside of the first positioning hole 52. At this time, the packing 53 can be pulled outward to replace the packing 53. When the first filter screen 67, the second filter screen 68, and the third filter screen 69 need to be replaced, the second push plate 612 can be pushed upward to disengage one end of the second push plate 612 from the inside of the second positioning hole 62. At this time, the support frame 63 can be pulled outward, and then the nut 66 can be rotated to make the nut 6 6. After detaching the upper outer surface of the positioning rod 65, the first filter screen 67, the second filter screen 68, and the third filter screen 69 can be removed from the inside of the mounting groove 64. Unused first filter screen 67, second filter screen 68, and third filter screen 69 can be installed inside the mounting groove 64, thereby completing the replacement of the replacement structure 6. When it is necessary to clean the rotating adsorption layer 74, the dividing cover 75 can be pulled upwards, and then the rotating adsorption layer 74 can be pulled upwards to disengage the insertion block 73 from the insertion groove 72 to complete the disassembly. Conversely, it can be reinstalled. The above is the complete working principle of this utility model.

[0036] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
