Description

Technical Field

[0001] This invention relates to the field of environmental protection deodorization technology, specifically to an environmental protection deodorization device with a chemical filter material structure. Background Technology

[0002] Environmental deodorization equipment, as a key component in controlling odor pollution and improving the living environment, is widely used in fields such as waste disposal, sewage treatment, livestock and poultry farming, and chemical production. Among these, deodorization equipment with chemical filter media structures, through chemical reactions such as neutralization, oxidation, and adsorption between the filter media and odorous substances, can efficiently remove various odorous components such as hydrogen sulfide, ammonia, and mercaptans, becoming a core technological solution for purifying high-concentration, complex-component odors. The core components of this type of equipment typically include a chemical filter media layer, airflow distribution components, a filter media support structure, inlet and outlet channels, and auxiliary reaction modules. Its purification efficiency is closely related to the contact area of ​​the chemical filter media, airflow uniformity, ease of filter media replacement, and the completeness of the reaction.

[0003] In response to this, this application designs an environmentally friendly deodorization device with a chemical filter media structure. Existing environmentally friendly deodorization devices mostly use a drawer-type structure for their chemical filter media. Although the drawer-type structure simplifies the replacement process to some extent, the filter media is tightly compressed in the filter media box. Although it can ensure a certain contact time, the airflow is prone to form a biased flow in the filter media layer, resulting in excessive consumption of local filter media and a decrease in overall purification efficiency. When the drawer-type filter media box is pulled out, malodorous gases and reaction dust are easily left in the filter media box, which will directly diffuse into the operating environment and cause secondary pollution. This not only increases cleaning costs, but also causes operators to come into contact with corrosive or irritating chemical dust, posing a safety hazard. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides an environmentally friendly deodorizing device with a chemical filter media structure. This effectively solves the problems of existing technologies where chemical filter media often employ a drawer-type structure, with the filter media tightly compressed within the filter media box. This can lead to airflow deviation within the filter media layer, resulting in excessive consumption of localized filter media and a decrease in overall purification efficiency. Furthermore, when the drawer-type filter media box is removed, residual odorous gases and reaction dust can easily remain inside, directly diffusing into the operating environment and causing secondary pollution. This can also lead to operators coming into contact with corrosive or irritating chemical dust, posing safety hazards.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides an environmentally friendly deodorization device with a chemical filter media structure, comprising:

[0007] The outer shell has vents on both the left and right sides. An exhaust fan is installed on the inner wall of the vent on the right side. From left to right, a primary installation frame, a medium-efficiency installation frame, and a high-efficiency installation frame are installed on the inner wall of the outer shell. Several filter boxes are slidably placed in the installation cavities on the upper and lower sides of the high-efficiency installation frame. A cover plate is detachably installed on the upper end of the filter box. A stirring part is provided on the several filter boxes and the high-efficiency installation frame. A docking part is provided on the outer shell and the high-efficiency installation frame.

[0008] The stirring section includes a pressure plate that is slidably installed on the inner wall of each filter box. The upper end of the pressure plate is connected to the cover plate by a compression spring. A support crossbar is provided inside the filter box. A double-headed heating tube is rotatably installed through the middle of the support crossbar. Mounting tubes that are rotatably sleeved on the outer wall of the double-headed heating tube are installed on both the left and right ends of the support crossbar. Stirring groups are symmetrically arranged on the support crossbars on the front and rear sides.

[0009] The docking section includes a connecting plate located on the upper side of the high-efficiency mounting frame, a docking plate on the upper side of the connecting plate, and several quick connectors evenly distributed from front to back installed at the lower end of the docking plate. The outer shell and the high-efficiency mounting frame are both equipped with docking assemblies.

[0010] Furthermore, the mixing assembly includes a supporting vertical rod installed on the upper end of the outer wall of the supporting horizontal rod. The supporting vertical rod slides through the pressure plate and the cover plate. Several material leakage holes are evenly distributed in a circle on the outer wall of the mounting tube, and several stirring blades are also evenly distributed in a circle on the outer wall of the mounting tube. The stirring blades and the material leakage holes are staggered. A winder with a wire outlet hole at the upper end is rotatably sleeved on the outer wall of the mounting tube at the end away from the supporting horizontal rod. The winder slides against the inner wall of the filter box.

[0011] Furthermore, the mixing assembly also includes two receiving slots on the outer wall of the mounting tube corresponding to the winder. A spiral spring is sleeved on the inner wall of the receiving slot. One end of the spiral spring is fixedly connected to the mounting tube, and the other end of the spiral spring is fixedly connected to the inner wall of the winder. A traction rope is also wound on the outer wall of the mounting tube corresponding to the winder. The end of the traction rope away from the mounting tube passes through the upper opening of the winder and is fixedly connected to a fixing head that passes through and is installed on the cover plate.

[0012] Furthermore, the mating part also includes alignment grooves located on the upper end of the connecting plate corresponding to several quick connectors, and the left end of the connecting plate also has several snap-fit ​​holes that are respectively connected to the corresponding alignment grooves, and the upper end of the high-efficiency mounting frame has clearance holes corresponding to the connecting plate.

[0013] Furthermore, the docking assembly includes a rectangular through hole at the upper end of the outer shell corresponding to the docking plate. Guide grooves communicating with the rectangular through hole are provided on the upper side of the outer walls at both the front and rear ends of the outer shell. A sliding plate is slidably installed in the guide groove. A mating slide rod is symmetrically installed at the lower end of the docking plate and slides through the corresponding sliding plate. A compression spring is sleeved on the part of the outer wall of the mating slide rod between the docking plate and the sliding plate. A limit disc is installed at the lower end of the mating slide rod.

[0014] Furthermore, the docking assembly also includes an electric push rod mounted on the outer wall of the rear end of the housing and the outer wall of the front end of the high-efficiency mounting frame via mounting bases. The telescopic end of the electric push rod is equipped with a support plate. The front and rear support plates slide against the outer wall of the high-efficiency mounting frame and the outer wall of the housing, respectively. The left end of the support plate has a matching sliding hole corresponding to the limiting disc. The outer wall of the limiting disc moves against the inner wall of the corresponding convex sliding hole.

[0015] Furthermore, several plate filters are slidably placed in the mounting cavities on both the upper and lower sides of the primary efficiency mounting frame, several bag filters are slidably placed in the mounting cavities on both the upper and lower sides of the medium efficiency mounting frame, and dust storage cavities are opened at the upper ends of the inner walls of the upper and lower mounting cavities of the high efficiency mounting frame.

[0016] Furthermore, the outer shell and the high-efficiency mounting frame have discharge holes symmetrically opened on the left and right sides of the two dust collection chambers at the rear end of the outer wall, and extraction pipes that are connected to the corresponding left and right discharge holes are symmetrically installed on the rear end of the outer wall.

[0017] Furthermore, a connecting rod is provided between the outer walls of each pair of adjacent upper and lower support crossbars. The connecting rod slides through the high-efficiency mounting frame, and the upper end of the connecting rod is fixedly connected to the outer wall of the corresponding support crossbar, while the lower end of the connecting rod is fixedly connected to the corresponding support vertical bar. The upper ends of several support vertical bars on the upper side are all fixedly connected to the connecting plate.

[0018] The technical solution provided by this invention has the following advantages compared with the prior art:

[0019] This invention provides an environmentally friendly deodorizing device with a chemical filter media structure. During the mixing and dispersion stage, as the installation pipe moves downward, several mixing blades can dig up the chemical filter media on the lower side of the installation pipe and flip it upward. Combined with several leakage holes, this effectively reduces the resistance of the chemical filter media to the downward movement of the installation pipe. During the upward movement of the installation pipe, the mixing blades change their action from digging up the chemical filter media downward to passively supporting the chemical filter media in the arc-shaped cavity and rotating around the installation pipe. At this time, the chemical filter media falling on the upward-facing side of the arc-shaped cavity of the mixing blade will assist the corresponding mixing blade in rotating around the installation pipe, while the arc-shaped cavity facing upward... The stirring blades on the upper side can also reduce the resistance to further upward rotation, which is conducive to the release of elastic potential energy by the tightly wound spiral spring, so that the traction rope can be wound back onto the outer wall of the installation tube. Similarly, with several material leakage holes, the resistance of the chemical filter material to the downward movement of the installation tube can be further reduced. By using the method of stirring and dispersing the chemical filter material by flipping it up and down, the clumping phenomenon that occurs when the chemical filter material absorbs moisture from the air when reacting with the gas to be treated can be avoided. Also, the problem that the airflow is easily deflected in the filter material layer when the chemical filter material is tightly compressed in the filter material box, which leads to excessive consumption of local filter material and a decrease in overall purification efficiency can be avoided.

[0020] As the chemical filter media undergoes multiple stirring and dispersion processes, the dust within the filter box falls into the upper and lower dust storage chambers of the high-efficiency mounting frame. An external vacuum pump simultaneously connects to both upper and lower extraction pipes, which, through discharge holes, periodically control the operation of the external vacuum pump to remove and clean residual dust from the dust storage chambers. Simultaneously, the uniform up-and-down agitation of the chemical filter media during drying also promptly removes vapors formed by moisture evaporation and residual gases between the filter media. This prevents the residual odorous gases and reaction dust from easily spreading into the operating environment and causing secondary pollution when the drawer-type filter box is removed. This not only increases cleaning costs but also poses a safety hazard by exposing operators to corrosive or irritating chemical dust. Attached Figure Description

Each quick connector 73 consists of an alignment rod and two spring-loaded locking rods on the left and right. A docking assembly 74 is provided on both the outer shell 1 and the high-efficiency mounting frame 5.

[0039] The mixing assembly 65 includes a supporting vertical rod 651 installed on the upper end of the outer wall of the supporting horizontal rod 62. The supporting vertical rod 651 slides through the pressure plate 61 and the cover plate. The outer wall of the mounting tube 64 is provided with several circumferentially evenly distributed material leakage holes. The outer wall of the mounting tube 64 is also provided with several circumferentially evenly distributed stirring blades 652. The stirring blades 652 are arc-shaped, and the stirring blades 652 and the material leakage holes are staggered. A winder 653 with a wire outlet hole at the upper end is rotatably sleeved on the outer wall of the mounting tube 64 away from the supporting horizontal rod 62. The winder 653 slides against the inner wall of the filter box 51.

[0040] The mixing assembly 65 also includes two receiving grooves on the outer wall of the mounting tube 64 corresponding to the winder 653. The receiving grooves are annular in design, and a spiral spring 654 is sleeved on the inner wall of the receiving groove.

A traction rope 655 is also wound on the outer wall of the mounting tube 64 corresponding to the winder 653. The end of the traction rope 655 away from the mounting tube 64 passes through the upper opening of the winder 653 and is fixedly connected to a fixing head 656 that is installed through the cover plate.

[0041] The docking part 7 also includes alignment grooves on the upper end of the connecting plate 71 corresponding to several quick connectors 73. The left end of the connecting plate 71 also has several snap-fit ​​holes that are connected to the corresponding alignment grooves. The upper end of the high-efficiency mounting frame 5 has clearance holes corresponding to the connecting plate 71.

[0042] The docking assembly 74 includes a rectangular through hole at the upper end of the outer shell 1 corresponding to the docking plate 72. Guide grooves communicating with the rectangular through hole are provided on the upper side of the outer walls at both the front and rear ends of the outer shell 1. A sliding plate 741 is slidably installed in the guide groove. A mating rod 742 is symmetrically installed at the lower end of the docking plate 72, sliding through the corresponding sliding plate 741. A compression spring is sleeved on the part of the outer wall of the mating rod 742 between the docking plate 72 and the sliding plate 741, and a limit disc is installed at the lower end of the mating rod 742.

[0043] The docking assembly 74 also includes an electric push rod 743, which is mounted on the outer wall of the rear end of the outer shell 1 and the outer wall of the front end of the high-efficiency mounting frame 5 via mounting bases. The telescopic end of the electric push rod 743 is equipped with a support plate 744. The front and rear support plates 744 slide against the outer wall of the high-efficiency mounting frame 5 and the outer wall of the outer shell 1, respectively. The left end of the support plate 744 is provided with a matching sliding hole corresponding to the limiting disc. The matching sliding hole is a convex design. The outer wall of the limiting disc moves against the inner wall of the corresponding convex sliding hole.

[0044] Several plate filters 31 are slidably placed in the mounting cavities on both the upper and lower sides of the primary mounting frame 3. Several bag filters 41 are slidably placed in the mounting cavities on both the upper and lower sides of the medium-efficiency mounting frame 4. Dust storage cavities are opened at the upper ends of the inner walls of the upper and lower mounting cavities of the high-efficiency mounting frame 5.

[0045] Both the outer casing 1 and the high-efficiency mounting frame 5 have discharge holes symmetrically opened on the left and right sides of the two dust storage chambers at the rear end of the outer wall. The outer casing 1 has extraction pipes 8 symmetrically installed on the rear end of the outer wall, which are connected to the corresponding left and right discharge holes.

[0046] A connecting rod 66 is provided between the outer walls of each pair of adjacent upper and lower support crossbars 62. The connecting rod 66 slides through the high-efficiency mounting frame 5, and the upper end of the connecting rod 66 is fixedly connected to the outer wall of the corresponding support crossbar 62. The lower end of the connecting rod 66 is fixedly connected to the corresponding support vertical bar 651. The upper ends of several support vertical bars 651 on the upper side are all fixedly connected to the connecting plate 71.

[0047] In practice:

[0048] First, the primary efficiency mounting frame 3, the secondary efficiency mounting frame 4, and the high efficiency mounting frame 5 in this application all adopt a detachable sealing plate structure with handles. This is prior art and will not be described in detail here. The connecting plate 71 is initially located in the clearance hole. At this time, the upper end of the connecting plate 71 is flush with the upper end of the high efficiency mounting frame 5 to facilitate the subsequent docking and fixing with the docking plate 72. The front and rear sliding plates 741 are initially located in the guide groove on the side away from the rectangular through hole. At this time, the docking plate 72 and the connecting plate 71 are in a separated state, and the front and rear mating sliding rods 742 are also in a separated state from the corresponding support plate 744. In addition, the left ventilation port of the outer casing 1 is connected to the external device inlet pipe, and the right ventilation port of the outer casing 1 is connected to the external device outlet pipe through the exhaust fan 2.

[0049] In the initial assembly stage, the workers first place the primary filter mounting frame 3, the medium-efficiency mounting frame 4, and the high-efficiency mounting frame 5 into the outer shell 1 in sequence, ensuring that the outer walls of the primary filter mounting frame 3, the medium-efficiency mounting frame 4, and the high-efficiency mounting frame 5 are tightly fitted to the inner wall of the outer shell 1. A sealing effect is achieved with the help of sealing filler material. It should be noted that several plate filters 31 are pre-slidably placed in the upper and lower mounting cavities of the primary filter mounting frame 3, several bag filters 41 are pre-slidably placed in the upper and lower mounting cavities of the medium-efficiency mounting frame 4, and several filter boxes 51 are pre-slidably placed in the upper and lower mounting cavities of the high-efficiency mounting frame 5. Each filter box 51 is filled with chemical filter media, and the corresponding pressure plate 61 is used to assist in compaction under the action of a compression spring.

[0050] During the docking and fixing stage, after assembly, the connecting plate 71 and the docking plate 72 are first docked and fixed: the two electric push rods 743 are controlled to move the support plate 744 upwards until the mating sliding hole on the support plate 744 is at the same horizontal height as the corresponding limiting disc. Then, the docking plate 72 is manually pushed by the operator, so that the docking plate 72 drives the two sliding plates 741 to slide along the corresponding guide grooves toward the rectangular through hole until the two sliding plates 741 slide synchronously to the position facing the rectangular through hole. At this time, the docking plate 72 will drive several quick connectors 73 to slide synchronously above the connecting plate 71. The two limiting discs will also move synchronously and slide into the mating sliding hole on the corresponding support plate 744, thereby achieving the effect of axial docking between the mating sliding rod 742 and the corresponding support plate 744.

[0051] Then, the two electric push rods 743 at the front and rear are controlled to simultaneously drive the support plate 744 to move downward. The two support plates 744 will drive the corresponding mating slide rods 742 to move downward synchronously through the limiting disc. The two mating slide rods 742 will drive several quick connectors 73 to move downward synchronously through the docking plate 72 until the quick connectors 73 are inserted into the corresponding alignment slots, thereby achieving the effect of docking and fixing the connecting plate 71 and the docking plate 72. During this process, the two spring-loaded locking rods on the left and right of the quick connectors 73 will be squeezed to avoid the collision, and then inserted into the corresponding locking holes under the action of the compression spring. The quick connectors 73 are also existing technology and will not be described in detail here.

[0052] In the deodorization and filtration stage, first turn on the exhaust fan 2 on the inner wall of the right ventilation port of the outer casing 1. Under the action of the exhaust fan 2, the gas to be treated will enter from the left ventilation port of the outer casing 1 and pass through the following filtration and deodorization process in sequence:

[0053] Pre-filtering: The gas to be treated first passes through the plate filter 31 in the pre-filter mounting frame 3 to remove large particulate impurities. Medium-efficiency filtration: The gas to be treated after pre-filtering continues to enter the medium-efficiency mounting frame 4, where it passes through the bag filter 41 to remove medium-sized particles and some odor precursors. High-efficiency deodorization: The gas to be treated after medium-efficiency filtration continues to enter the high-efficiency mounting frame 5, allowing the chemical filter media to fully contact the gas to be treated. Odor molecules are absorbed and decomposed through chemical reaction. The treated clean gas is discharged through the right-side vent and then through the external exhaust pipe. At this point, the concentration of the target pollutants in the gas must meet the preset standard. The treatment efficiency is improved through staged filtration to ensure that the gas meets the emission standards. Furthermore, the sequential passing through the pre-filter and medium-efficiency filter protects the subsequent chemical filter media, which can extend the service life of the chemical filter media and reduce impurity blockage, thereby reducing maintenance costs.

[0054] During the mixing and dispersion stage, after a period of deodorization and filtration, several double-headed heating tubes 63 can be started simultaneously to heat the filter media. The heat will be transferred to the chemical filter media through the installation tube 64. Then, the two electric push rods 743 at the front and rear will simultaneously drive the corresponding support plates 744 to move up and down at a uniform speed. At this time, the docking plate 72 will drive the connecting plate 71 to move up and down synchronously. Under the cooperation of several support vertical rods 651 and connecting rods 66, the connecting plate 71 will drive several support horizontal rods 62 on the upper and lower sides to move up and down synchronously. At this time, the double-headed heating tubes 63, the installation tubes 64 and the winder 653 will all move up and down synchronously following the support horizontal rods 62.

[0055] Since several fixing heads 656 are fixed to the corresponding cover plates respectively, when the installation tube 64 moves downward, under the combined action of the traction rope 655 and the spiral spring 654, the traction rope 655 wound on the installation tube 64 will gradually extend out of the corresponding winder 653. At this time, the stirring group 65 gradually tightens and stores elastic potential energy, and the installation tube 64 will drive the corresponding several stirring blades 652 to rotate at a constant speed and stir the chemical filter material together. Under the action of several leakage holes, the installation tube 64 will continuously throw out the chemical filter material in the tube and remix it with the chemical filter material in the filter box 51.

[0056] When the installation tube 64 moves upward, the tightly wound spiral spring 654 will release its elastic potential energy. At this time, the installation tube 64 will rotate in the opposite direction at a uniform speed, and the traction rope 655 will gradually retract to the corresponding winder 653 and wind around the outer wall of the installation tube 64 to return to its original position. During this period, the installation tube 64 will also drive the corresponding several stirring blades 652 to rotate in the opposite direction at a uniform speed and stir the chemical filter material together. Under the action of several leakage holes, the installation tube 64 will also continuously throw out the chemical filter material in the tube and remix it with the chemical filter material in the filter box 51.

[0057] It should be noted that, due to the arc-shaped structure of the stirring blades 652, during the downward movement of the mounting tube 64, several stirring blades 652 can dig up the chemical filter media on the lower side of the mounting tube 64 and flip it upwards. Combined with several leakage holes, this effectively reduces the resistance of the chemical filter media to the downward movement of the mounting tube 64. During the upward movement of the mounting tube 64, since the rotation direction of the stirring blades 652 is opposite to before, the action of digging up the chemical filter media downwards changes to passively supporting the chemical filter media in the arc-shaped cavity and rotating around the mounting tube 64. At this time, the chemical filter media falling on the upward-facing side of the arc-shaped cavity of the stirring blades 652 will assist the corresponding stirring blades 652 in rotating around the mounting tube 64. Meanwhile, the upward-facing stirring blade 652 of the arc-shaped cavity can reduce the resistance to further upward rotation, which is conducive to the release of elastic potential energy by the tightly wound spiral spring 654, so that the traction rope 655 can be wound around the outer wall of the installation tube 64 again. Similarly, with several material leakage holes, the resistance of the chemical filter material to the downward movement of the installation tube 64 can be further reduced. By stirring and dispersing the chemical filter material by repeatedly turning it up and down, the clumping phenomenon that occurs when the chemical filter material absorbs moisture from the air when reacting with the gas to be treated can be avoided, as well as the problem that the airflow is easily deflected in the filter material layer when the chemical filter material is tightly compressed in the filter material box, resulting in excessive consumption of local filter material and a decrease in overall purification efficiency.

[0058] Furthermore, when the chemical filter media is agitated during the upward or downward movement of the mounting tube 64, the corresponding pressure plate 61 can adaptively slide along the inner wall of the filter box 51 in the vertical direction to maintain the compactness of the chemical filter media. In addition, several double-headed heating tubes 63 can work together with the mounting tube 64 to heat the chemical filter media they are in contact with, thereby enabling the heating source to directly contact the filter media and continuously agitate the chemical filter media particles through stirring. This breaks the limitation of static drying where the surface layer is easy to dry but the core is difficult to dry, and avoids the problem of local overheating or incomplete drying of the chemical filter media.

[0059] During this process, dust is often generated due to the reaction between the chemical filter media and the gas to be treated. As the chemical filter media is repeatedly stirred and dispersed, the continuous friction and collision between the double-headed heating tube 63 and the mounting tube 64 and the filter media particles will significantly aggravate the mechanical wear of the chemical filter media. The dust in the filter box 51 will fall into the upper and lower dust storage chambers of the high-efficiency mounting frame 5. The upper and lower extraction pipes 8 can be connected simultaneously by an external vacuum pump. The upper and lower extraction pipes 8 will periodically control the operation of the external vacuum pump through the discharge hole to remove and clean the residual dust in the dust storage chamber. At the same time, by turning the chemical filter media up and down at a uniform speed and drying it, the vapor formed by the evaporation of water and the gas to be treated remaining between the chemical filter media can also be discharged in time. This avoids the malodorous gas and the dust after the reaction remaining in the filter box 51 from directly spreading to the operating environment and causing secondary pollution when the drawer-type filter box 51 is pulled out. This not only increases the cleaning cost, but also causes operators to come into contact with corrosive or irritating filter media residues, which poses a safety hazard.

[0060] During the chemical filter media replacement stage, when the chemical filter media needs to be replaced, the operator uses a disassembly tool to simultaneously squeeze the spring-loaded locking rods on several quick connectors 73, causing them to disengage from the corresponding locking holes. This allows the docking plate 72 to be lifted upwards, releasing its docking and fixing effect with the connecting plate 71. Then, the operator manually pushes the docking plate 72, causing it to drive the two sliding plates 741 at the front and rear to slide away from the rectangular through hole along their corresponding guide grooves, returning to their original positions. During this process, the two limiting discs at the front and rear will also move synchronously to their original positions and disengage from the mating sliding holes on the corresponding support plate 744. At this point, the sliding plates 741 and support plates 744 will no longer obstruct the entry and exit of the high-efficiency installation frame 5. The operator can then pull the high-efficiency installation frame 5 out of the outer shell 1 and remove several filter boxes 51 from the installation cavity of the high-efficiency installation frame 5. The cover plate can then be removed to replace the chemical filter media.

[0061] In summary, this application has the following advantages:

[0062] Advantage 1: During the docking and fixing stage, firstly, the mating sliding hole on the support plate 744 is controlled to be at the same horizontal height as the corresponding limiting disc. Then, the docking plate 72 is manually pushed by the operator, so that the front and rear sliding plates 741 slide synchronously to the position facing the rectangular through hole. The front and rear limiting discs will also move synchronously and slide into the mating sliding hole on the corresponding support plate 744, thereby achieving the effect of axial docking between the mating sliding rod 742 and the corresponding support plate 744. Then, the front and rear electric push rods 743 are controlled to simultaneously drive the support plate 744 downward until several quick connectors 73 are inserted into the corresponding alignment grooves, thereby achieving the effect of docking and fixing between the connecting plate 71 and the docking plate 72.

[0063] Secondly, in the deodorization and filtration stage, the exhaust fan 2 on the inner wall of the right ventilation port of the outer casing 1 is turned on first. Under the action of the exhaust fan 2, the gas to be treated will enter from the left ventilation port of the outer casing 1 and pass through the pre-filter, medium-efficiency filter and high-efficiency deodorization in sequence. The treated clean gas is discharged through the right ventilation port and discharged through the external exhaust pipe. At this time, the concentration of the target pollutants in the gas must meet the preset standard. The treatment efficiency is improved by the staged filtration to ensure that the gas meets the emission standards. In addition, the pre-filter and medium-efficiency filter protect the subsequent chemical filter media, which can extend the service life of the chemical filter media and reduce the blockage of impurities, thus reducing maintenance costs.

[0064] Thirdly, during the mixing and dispersion stage, the two electric push rods 743 simultaneously drive the corresponding support plate 744 to move up and down at a uniform speed. At this time, the double-headed heating tube 63, the mounting tube 64, and the winder 653 will all move up and down synchronously following the support crossbar 62. When the mounting tube 64 moves down or up, the traction rope 655 wound on the mounting tube 64 will gradually extend or retract the corresponding winder 653. During this period, the mixing group 65 gradually tightens to store or release elastic potential energy, and the mounting tube 64 will drive the corresponding several mixing blades 652 to rotate in the forward or reverse direction at a uniform speed, and together stir the chemical filter material. Under the action of several leakage holes, the mounting tube 64 will continuously throw out the chemical filter material in the tube and remix it with the chemical filter material in the filter box 51.

[0065] Fourthly, during the downward movement of the installation pipe 64, several stirring blades 652 can dig up the chemical filter material on the lower side of the installation pipe 64 and flip it upwards. During the upward movement of the installation pipe 64, the stirring blades 652 will change from digging down the chemical filter material to passively supporting the chemical filter material in the arc-shaped cavity and rotating around the installation pipe 64. At this time, the chemical filter material falling on the upward side of the arc-shaped cavity of the stirring blade 652 will assist the corresponding stirring blade 652 in rotating around the installation pipe 64. By using the method of stirring and dispersing the chemical filter material by flipping it up and down, the clumping phenomenon that occurs when the chemical filter material absorbs moisture from the air when reacting with the gas to be treated can be avoided. Also, the problem of the chemical filter material being tightly compressed in the filter material box, causing the airflow to easily form a deviation in the filter material layer, resulting in excessive consumption of local filter material and a decrease in overall purification efficiency can be avoided.

[0066] Fifthly, when the chemical filter media is agitated during the upward or downward movement of the mounting tube 64, the corresponding pressure plate 61 can adaptively slide along the inner wall of the filter box 51 in the vertical direction to maintain the compactness of the chemical filter media. In addition, several double-headed heating tubes 63 can work together with the mounting tube 64 to heat the chemical filter media they are in contact with, thereby realizing that the heating source directly contacts the filter media and continuously agitates the chemical filter media particles through stirring. This breaks the limitation of the surface layer drying easily and the core layer drying difficult in static drying, and avoids the problem of local overheating or incomplete drying of the chemical filter media.

[0067] Advantage six: As the chemical filter media undergoes multiple stirring and dispersion processes, the dust inside the filter box 51 will fall into the upper and lower dust storage chambers of the high-efficiency mounting frame 5. An external vacuum pump can simultaneously connect to the upper and lower extraction pipes 8. These extraction pipes 8, through discharge holes, periodically control the operation of the external vacuum pump to remove and clean the residual dust from the dust storage chambers. Simultaneously, by uniformly turning the chemical filter media up and down and during its drying process, the vapor formed by moisture evaporation and the residual gases between the chemical filter media can be promptly removed. This prevents the residual odorous gases and reaction dust from easily spreading into the operating environment and causing secondary pollution when the drawer-type filter box 51 is pulled out. This not only increases cleaning costs but also poses a safety hazard by exposing operators to corrosive or irritating chemical dust residues.
