Description

Technical Field

[0001] This application relates to the technical field of air purification, and in particular, to a vertical wet high-efficiency dust collector. Background Art

[0002] A wet dust collector or a wet dust scrubber is a mechanical device that uses a liquid phase as a medium and a gas phase as a carrier. Under the action of mechanical force, the liquid phase is atomized into tiny droplets, and through multiple impacts at a certain speed, the purification process is completed between the gas-liquid phases. The purification process is completed while collecting waste gas, and then the purified air is discharged. At present, most wet dust collectors or wet dust scrubbers separate dust particles by mixing gas and liquid and then dehydrating through cyclone. Therefore, the dust removal efficiency is relatively low, generally around 95%. In view of the low dust removal efficiency of existing wet dust collectors, especially in harsh environments such as coal preparation plants and ore dressing plants, the indoor dust concentration is very high. The air purified by a wet dust collector or a wet dust scrubber far fails to meet the occupational health dust emission standards for indoor discharge. Therefore, it is necessary to lay a chimney to discharge the purified air outdoors. Even if the purified air is discharged outdoors, the emission standards of some working conditions cannot meet the outdoor dust emission standards. In addition, in the northern region, outdoor discharge not only requires laying pipelines and chimneys, increasing material and installation costs, but also causes a large amount of heat loss in the air discharge. According to the above situation, in order to improve the occupational health of enterprise employees, meet the environmental protection emission requirements and reduce the comprehensive cost of dust removal equipment, there is an urgent need for a dust collector that can meet the indoor discharge requirements. Summary of the Invention

[0003] The purpose of the embodiments of this application is to provide a vertical wet high-efficiency dust collector, which can solve the problem that the existing dust collectors cannot meet the requirement of discharging the treated air back into the room.

[0004] The embodiments of this application provide a vertical wet high-efficiency dust collector, including:

[0005] A primary cyclone dust removal device for performing primary dust removal on the gas; including a first housing, a fan, a cyclone vane and a primary water spraying assembly. The first housing includes an air inlet, the primary water spraying assembly is arranged at the air inlet, and the fan is used to drive the gas to enter the first housing from the air inlet to mix with the water film sprayed by the primary water spraying assembly; the cyclone vane is arranged in the first housing to guide the gas to rotate;

[0006] The secondary interception dust removal device is arranged at the rear end of the primary cyclone dust removal device for secondary dust removal of the gas. The secondary interception dust removal device includes a second housing, an interception plate, and a secondary water spraying assembly. The second housing is connected to the air outlet of the first housing. The interception plate is arranged inside the second housing, and the interception plate is densely provided with air permeable holes. The secondary water spraying assembly is located on the side of the interception plate close to the first housing.

[0007] The demisting and dehydration device is arranged at the rear end of the secondary interception dust removal device for dehydrating the gas.

[0008] In the above implementation process, a primary cyclone dust removal device, a secondary interception dust removal device, and a demisting and dehydration device are provided. Driven by the fan, air enters the primary cyclone dust removal device from the air inlet of the first housing and is fully mixed and collided with the water film. Most of the dust is captured by the water during this process. Then, the air rotates and advances in the first housing after passing through the cyclone blades. The dust-containing water droplets entrained in the high-speed rotating air are heavier and will be thrown towards the inner wall of the first housing under the action of centrifugal force, thereby realizing the separation of water and gas. At this time, about 95% of the dust in the air is removed. The air that has completed the first dust removal enters the secondary interception dust removal device for secondary dust removal. In the secondary interception dust removal device, the air is fully mixed with the water film manufactured by the secondary water spraying assembly again. A small amount of dust entrained in the air is captured by the water. Most of the water droplets carrying dust are intercepted during the process of the air passing through the interception plate. More than 99% of the dust is removed after the air passes through the air permeable holes on the interception plate, meeting the environmental protection standard for indoor emission after dust removal. At the same time, before the air is truly discharged, most of the water vapor contained in the air is removed through the demisting and dehydration device, avoiding the problem that the dust-laden sewage is discharged into the air and then aggravates the air dust pollution after drying. In addition, the vertical wet high-efficiency dust collector in this solution has a large processing capacity, has no requirements for the on-site dust concentration, and has a high dust removal efficiency, and is particularly suitable for environments with a large amount of dust such as coal preparation and ore dressing.

[0009] In summary, the vertical wet high-efficiency dust collector of the present application performs secondary dust removal treatment on the air through cyclone dust removal and interception dust removal, and then performs demisting and dehydration treatment on the air before discharging it. It can achieve the removal of more than 99% of the air dust and complete the drying treatment, meeting the environmental protection standard for directly discharging the treated air into the indoor. Since the dust removal rate of the air is higher, there is no need to worry about the problem that the air discharge cannot meet the environmental protection requirements. And the treated air can be directly discharged into the indoor, so there is no need to lay pipelines, chimneys and other structures, reducing the equipment materials and installation costs. At the same time, it can also avoid the problem of large heat loss caused by discharging indoor air to the outside.

[0010] Further, the blower is an axial flow fan, which includes a connected motor and an impeller. The motor is fixed inside the first housing, and the impeller is arranged inside the first housing near the air inlet.

[0011] In the above implementation process, using an axial flow fan to drive the air flow has the characteristics of fast wind speed and high wind pressure. In harsh environments such as coal preparation plants and ore dressing plants, the pipeline system is often long and complex, and it is easy to generate large resistance. This solution uses an axial flow fan to effectively overcome the resistance of the on-site pipeline, avoiding the problem that the resistance brought by the long pipeline reduces the air volume and affects the dust removal efficiency. The motor of the blower is arranged inside the first housing, which can make full use of the space inside the first housing, reduce the volume of the entire primary cyclone dust removal device, and has the advantage of a compact structure. At the same time, it can keep the air inlet unobstructed, so that the air can be smoothly drawn into the first housing by the impeller.

[0012] Further, the blower further includes a motor housing, which covers the outer circumference of the motor, and the swirl vane is connected between the motor housing and the first housing.

[0013] In the above implementation process, by adding a motor housing and cleverly connecting the swirl vane between the motor housing and the first housing, multiple optimization effects are achieved. The motor housing not only builds a solid protection barrier for the motor, preventing the erosion of the external environment, but also significantly enhances the overall structural stability and operation safety of the dust removal device. Importantly, the motor housing is placed at the central axis position of the first housing, and together with the inner wall of the housing, it encloses an annular space. This innovative design uses this space to place the swirl vane, thus greatly optimizing the rotation path of the air flow. The swirl vane can efficiently guide the air flow to rotate at high speed inside the first housing. During this process, the dust-containing droplets are effectively separated by the centrifugal force and thrown towards the inner wall of the housing, achieving deep purification of the dust particles in the air.

[0014] Further, it further includes a water tank. The secondary interception dust removal device is connected to the top or side of the water tank, and the demisting and dehydration device is connected to the top of the water tank. The water separated by the primary cyclone dust removal device, the secondary interception dust removal device, and the demisting and dehydration device is collected through the water tank.

[0015] In the above implementation process, by introducing a water tank to collect the sewage generated during the dust removal process, centralized treatment of the sewage can be achieved, avoiding the random discharge of sewage from polluting the workshop. At the same time, since the wet treatment method of this solution has low requirements for the purity of water, the recycled sewage can also be recycled back to the dust collector for reuse, which not only promotes the recycling of water resources, reduces wastewater discharge, but also brings higher application value and environmental protection benefits to the vertically arranged wet high-efficiency dust catcher.

[0016] Furthermore, the first housing is cylindrical, and a swirl collection groove is provided on one side of the first housing. The swirl collection groove is connected to a sewage discharge pipe leading to the water tank.

[0017] In the above implementation process, the swirl collection groove is arranged on one side of the first housing, which can collect the dust-containing water droplets rotating along the inner wall of the first housing and discharge them centrally into the water tank through the sewage discharge pipe, realizing the centralized treatment of the sewage generated by the primary swirl dust removal device and preventing the sewage generated in this process from flowing into the secondary interception dust removal device and affecting the secondary dust removal operation.

[0018] Furthermore, the second housing is square tube-shaped, with an installation groove provided on its inner wall and an installation opening provided on the side. The interception plate can be inserted into the second housing through the installation opening, and the side edge of the interception plate is clamped in the installation groove to achieve fixation.

[0019] In the above implementation process, setting the second housing as a square tube shape facilitates the peripheral part of the interception plate inserted from the side installation opening to be in close contact with the inner wall of the second housing, enabling the air passing through the inside of the second housing to pass through the interception of the interception plate; after the interception plate is inserted into the second housing through the installation opening, its side edge can be tightly clamped in the installation groove, thus achieving firm fixation. This design not only simplifies the installation process of the interception plate but also ensures its stability and reliability during operation. Importantly, since the interception plate may become blocked after being used for a certain period of time, the method of inserting from the side installation opening facilitates its disassembly and replacement, extends the service life of the equipment, and ensures high dust removal efficiency.

[0020] Furthermore, the installation groove includes a first limiting strip and a second limiting strip arranged at intervals. The first limiting strip is straight, and the second limiting strip includes a sliding-in section and a supporting section that form an angle with each other. The sliding-in section is arranged parallel to the first limiting strip, and the distance between the sliding-in section and the first limiting strip is greater than the thickness of the interception plate. The supporting section is inclined towards the direction where the first limiting strip is located relative to the sliding-in section, and the distance between the end of the supporting section away from the sliding-in section and the first limiting strip does not exceed the thickness of the interception plate; a tightening screw is threadedly installed at one end of the sliding-in section away from the supporting section, and the interception plate is tightly pressed against the first limiting strip by jointly pressing the interception plate with the supporting section and the tightening screw.

[0021] In the above implementation process, the installation groove includes a first limit strip and a second limit strip arranged at intervals, wherein the innovative design of the second limit strip is particularly critical. The second limit strip is composed of a slide-in section and a support section. The slide-in section is parallel to the first limit strip and the spacing is greater than the thickness of the interception plate, so that the interception plate can be easily inserted. It is particularly worth mentioning that the support section is inclined in the direction of the first limit strip and forms an angle with the slide-in section. The end away from the slide-in section is spaced from the first limit strip by no more than the thickness of the interception plate. Such a design enables the interception plate to be effectively supported and limited after insertion. The tightening screw installed with a thread at one end of the slide-in section away from the support section can be further tightened by rotating the tightening screw on the side of the interception plate away from the support section. This structure not only compensates for the possible processing errors of the interception plate, but also greatly enhances the stability of the interception plate after installation. Under the action of high-speed airflow, this fastening method can effectively avoid the vibration of the interception plate and ensure the overall performance and operation safety of the dust removal device. In summary, the fine design of the installation groove of this scheme not only simplifies the installation process of the interception plate, but also significantly improves the stability and reliability of the interception plate in the working state.

[0022] Furthermore, the interception plate is a chord grid plate or a wire mesh.

[0023] In the above implementation process, the interception plate is selected as a chord plate or a wire mesh, both of which have significant advantages in the field of dust removal. The chord plate, with its unique structure, can effectively intercept large dust particles in the air while allowing airflow to pass smoothly and reduce resistance. The wire mesh, with its dense mesh, can capture finer dust particles and improve dust removal efficiency. Choosing a chord plate or a wire mesh as the interception plate material not only meets the dust removal requirements of the vertically arranged wet high-efficiency dust collector, but also can extend the service life of the interception plate to a certain extent. This is because both materials have strong wear resistance and corrosion resistance and can maintain stable performance in harsh working environments. In addition, the installation and maintenance of the chord plate and the wire mesh are relatively simple. The above-mentioned structural design such as the installation slot and the tightening screw can achieve quick installation and disassembly, which is convenient for cleaning and replacement of the interception plate, ensuring that the dust removal device is always in the best working condition.

[0024] Furthermore, at least two parallel intercepting plates are provided in the second shell, and the air holes on each intercepting plate are staggered.

[0025] In the above implementation process, the provision of multiple interception plates increases the length of the air dust removal path, so that dust droplets in the air have more opportunities to contact and be captured by the interception plates. At the same time, the staggered arrangement of the air holes further disrupts the flow state of the airflow, making it more difficult for dust droplets to escape in the airflow, thereby improving the dust removal efficiency.

[0026] Further, the demisting and dehydrating device includes a third housing, demisting baffle plates, and an exhaust hood. The demisting baffle plates are arranged in an inverted V shape inside the third housing, and the exhaust hood is installed on the exhaust side of the third housing.

[0027] In the above implementation process, the demisting baffle plates are designed in an inverted V shape, which can increase the demisting area of the demisting baffle plates, improve the demisting ability, and at the same time, the demisting baffle plates can be inclined so that the air flow can fully impact the demisting baffle plates, making the demisting more efficient. An exhaust hood is arranged on the exhaust side of the third housing, which can guide the air flow to be horizontally dispersed around, avoiding the concentrated blowing of the air flow.

Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0040] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0041] Referring to Figures 1-9 , the embodiment of the present application provides a vertically arranged wet high-efficiency dust collector, including: a primary cyclone dust removal device 1 for performing primary dust removal on gas; including a first housing 11, a fan 13, cyclone vanes 14 and a primary water spraying assembly 12. The first housing 11 includes an air inlet 111. The primary water spraying assembly 12 is arranged at the air inlet 111. The fan 13 is used to drive gas to enter the first housing 11 from the air inlet 111 to be mixed with the water film sprayed by the primary water spraying assembly 12. The cyclone vanes 14 are arranged in the first housing 11 to guide the gas to rotate;

[0042] A secondary interception dust removal device 2 is arranged at the rear end of the primary cyclone dust removal device 1 for performing secondary dust removal on gas. The secondary interception dust removal device 2 includes a second housing 21, an interception plate 23 and a secondary water spraying assembly 22. The second housing 21 is connected to the air outlet of the first housing 11. The interception plate 23 is arranged in the second housing 21. The interception plate 23 is densely provided with air permeable holes. The secondary water spraying assembly 22 is located on the side of the interception plate 23 close to the first housing 11;

[0043] The demisting and dehydration device 3 is arranged at the rear end of the secondary interception and dust removal device 2 for dehydrating the gas.

[0044] Optionally, the primary water spraying assembly 12 includes a water pipe, a valve, and a nozzle. The water pipe extends from the outside into the first housing 11. The nozzle is connected to the end of the water pipe located inside the first housing 11 for spraying water to form a water film. The valve is arranged in the middle of the water pipe to control the on-off of water. When the valve is opened, water sprays out from the nozzle to form a water film that can mix with air. Among them, the valve is preferably provided with a solenoid valve and a manual valve. After the pipeline is connected, the manual valve is in the normally open state, and the solenoid valve is used to remotely control the on-off of the water flow electrically; when it is not used for a long time, or when the solenoid valve fails, the manual valve can be turned off to cut off the water. The nozzle is preferably a spiral nozzle, which can achieve uniform spraying of water supply and is not prone to nozzle blockage problems.

[0045] The function of the secondary water spraying assembly 22 is the same as that of the primary water spraying assembly 12, and specifically can be set with reference to the primary water spraying assembly 12.

[0046] Based on the vertical wet high-efficiency dust collector of this embodiment, a primary cyclone dust removal device 1, a secondary interception and dust removal device 2, and a demisting and dehydration device 3 are provided. Driven by the fan 13, air enters the primary cyclone dust removal device 1 from the air inlet 111 of the first housing 11 and fully mixes and collides with the water film. Most of the dust is captured by water during this process. Then, the air rotates and advances in the first housing 11 after passing through the cyclone blades 14. The dust-containing water droplets entrained in the high-speed rotating air are heavier and will be thrown towards the inner wall of the first housing 11 under the action of centrifugal force to achieve water-gas separation. At this time, about 95% of the dust in the air is removed; the air that has completed the first dust removal enters the secondary interception and dust removal device 2 for secondary dust removal. In the secondary interception and dust removal device 2, the air is re-mixed with the water film manufactured by the secondary water spraying assembly 22. A small amount of dust entrained in the air is captured by water. Most of the water droplets carrying dust are intercepted during the process of the air passing through the interception plate 23. More than 99% of the dust is removed after the air passes through the ventilation holes on the interception plate 23, and the environmental protection standard for indoor emission after dust removal can be achieved; at the same time, before the air is truly discharged, most of the water vapor contained in the air is removed through the demisting and dehydration device 3 to avoid the problem that the dust-containing sewage is discharged into the air and then aggravates the air dust pollution after drying. In addition, the vertical wet high-efficiency dust collector of this solution has a large processing capacity, has no requirement for the on-site dust concentration, and has a high dust removal efficiency, and is particularly suitable for environments with a large amount of dust such as coal preparation and ore dressing.

[0047] In summary, the vertical wet high-efficiency dust collector performs secondary dust removal on the air through cyclone dust removal and interception dust removal, and then performs demisting and dehydration treatment on the air before discharging it. It can achieve the removal of more than 99% of air dust and complete the drying treatment, meeting the environmental protection standard of directly discharging the treated air indoors. Since the dust removal rate of the air is higher, there is no need to worry about the problem that the air discharge cannot meet the environmental protection requirements. Moreover, the treated air can be directly discharged indoors, so there is no need to lay pipelines, chimneys and other structures, reducing the equipment materials and installation costs. At the same time, it can also avoid the problem of large heat loss caused by the discharge of indoor air outdoors.

[0048] In some embodiments, the fan 13 is an axial flow fan 13, which includes a connected motor 131 and an impeller 132. The motor 131 is fixed inside the first housing 11, and the impeller 132 is located inside the first housing 11 near the air inlet 111.

[0049] Specifically, using the axial flow fan 13 to drive the air flow has the characteristics of fast wind speed and high wind pressure. In harsh environments such as coal preparation plants and ore dressing plants, the pipeline system is often long and complex, and it is easy to generate large resistance. This solution uses the axial flow fan 13 to effectively overcome the resistance of the on-site pipeline, avoiding the problem that the resistance brought by the long pipeline reduces the air volume and affects the dust removal efficiency. The motor 131 of the fan 13 is arranged inside the first housing 11, which can make full use of the space inside the first housing 11, reduce the volume of the entire primary cyclone dust removal device 1, and has the advantage of compact structure. At the same time, it can keep the air inlet 111 unobstructed, so that the air can be smoothly drawn into the first housing 11 by the impeller 132.

[0050] In some embodiments, referring to Figure 4 , the fan 13 further includes an outer cover of the motor 131, and the outer cover of the motor 131 covers the outer circumference of the motor 131. The swirl vane 14 is connected between the outer cover of the motor 131 and the first housing 11.

[0051] Optionally, a plurality of swirl vanes 14 are arranged around the circumference of the outer cover of the motor 131, and the number is 5-9, preferably 7; each swirl vane 14 is inclined to guide the air flow to rotate spirally.

[0052] Specifically, by adding the motor 131 housing and cleverly connecting the swirl vane 14 between the motor 131 housing and the first housing 11, multiple optimization effects are achieved. The motor 131 housing not only constructs a solid protection barrier for the motor 131, preventing the erosion of the external environment, but also significantly enhances the overall structural stability and operation safety of the dust removal device. Importantly, the motor 131 housing is placed at the central axis position of the first housing 11, and together with the inner wall of the housing, it encloses an annular space. This innovative design utilizes this space to place the swirl vane 14, thus greatly optimizing the rotation path of the air flow. The swirl vane 14 can efficiently guide the air flow to rotate at high speed within the first housing 11. During this process, the dust-containing droplets are effectively separated under the action of centrifugal force and thrown towards the inner wall of the housing, achieving deep purification of the dust particles in the air.

[0053] In some embodiments, referring to Figures 1-2 , it further includes a water tank 4. The secondary interception dust removal device 2 is connected to the top or side of the water tank 4, and the demisting and dehydration device 3 is connected to the top of the water tank 4. The water tank 4 collects the water separated by the primary swirl dust removal device 1, the secondary interception dust removal device 2, and the demisting and dehydration device 3.

[0054] In the above implementation process, by introducing the water tank 4 to collect the sewage generated during the dust removal process, centralized treatment of the sewage can be achieved, avoiding the random discharge of sewage from polluting the workshop. At the same time, since the wet treatment method of this solution has low requirements for the purity of water, the recycled sewage can also be recycled back to the dust collector for utilization, which not only promotes the recycling of water resources, reduces wastewater discharge, but also brings higher application value and environmental protection benefits to the vertically arranged wet high-efficiency dust catcher.

[0055] Optionally, when the secondary interception dust removal device 2 is connected to the side of the water tank 4, the machine is in a horizontal form, suitable for scenarios with a relatively low factory building height and a relatively spacious area; when the secondary interception dust removal device 2 is connected to the top of the water tank 4, the machine is in a vertical form, suitable for scenarios with a relatively high factory building height, and it has the advantage of a relatively small floor area. For convenient adjustment and installation according to different scenarios, referring to Figure 9, the water tank 4 includes a water tank 4 housing. A first connection port 42 is respectively provided at the top and side of the water tank 4 housing. The first connection port 42 is used to connect with the secondary interception and dust removal device 2, so that the air after secondary dust removal can enter the water tank 4 housing. At the same time, a protection cover plate 44 is installed at one of the first connection ports 42 for sealing. During equipment assembly, the secondary interception and dust removal device 2 is connected to one of the first connection ports 42, and the other first connection port 42 is installed with a protection cover plate 44 to be closed. In this way, this solution has the advantage of being applicable to a variety of installation scenarios. In addition, a second connection port 42 is also provided at the top of the water tank 4 housing for connecting with the demisting and dehydration device 3. The airflow in the water tank 4 housing can enter the demisting and dehydration device 3 through the second connection port 42, and the water mist intercepted by the demisting and dehydration device 3 can drip back into the water tank 4 housing through the second connection port 42.

[0056] Optionally, a sewage discharge interface 47 is provided at the bottom of the water tank 4 housing. The sewage discharge interface 47 can be connected to an external drainage pipe to discharge water. The discharged water can be reused after sedimentation and filtration. A flushing interface 46 is also provided on the side of the water tank 4 housing. When it is necessary to clean the inside of the water tank 4 housing, a high-pressure pipeline can be connected to the flushing interface 46 to flush water into it. An observation window 45 is also provided on the side wall of the water tank 4 housing. The internal situation of the water tank 4 housing can be observed through the observation window 45. An inspection opening is also provided on one side of the water tank 4 housing. An inspection cover plate 48 is installed at the inspection opening. When necessary, the inspection cover plate 48 can be opened to enter the water tank 4 housing for maintenance operations.

[0057] In some embodiments, referring to Figures 2-3 , the first housing 11 is cylindrical. A swirl collection tank 112 is provided on one side of the first housing 11. The swirl collection tank 112 is connected to a sewage discharge pipe 43 leading to the water tank 4.

[0058] Specifically, the swirl collection tank 112 is provided on one side of the first housing 11, which can collect the dust-containing water droplets rotating along the inner wall of the first housing 11 and discharge them centrally into the water tank 4 through the sewage discharge pipe 43, realizing the centralized treatment of the sewage generated by the primary swirl dust removal device 1 and preventing the sewage generated during this process from flowing into the secondary interception and dust removal device 2 and affecting the secondary dust removal operation.

[0059] Optionally, referring to Figure 5 , a drainage connection tank 214 corresponding to the swirl collection tank 112 is provided on one side of the second housing 21. The bottom of the drainage connection tank 214 is connected to the sewage discharge pipe 43, and the sewage discharge pipe 43 leads to the water tank 4, so that the water collected by the swirl collection tank 112 can flow downward to the drainage connection tank 214 and then be discharged into the water tank 4 through the sewage discharge pipe 43. In this way, it can be realized that the drainage of the primary swirl dust removal device 1 completely avoids the interception plate 23.

[0060] In some embodiments, referring to Figures 5-7 , the second housing 21 is in the shape of a square tube, an installation groove 212 is provided on its inner wall, and an installation opening 211 is provided on the side. The intercepting plate 23 can be inserted into the second housing 21 through the installation opening 211, and the side edge of the intercepting plate 23 is clamped in the installation groove 212 to achieve fixation.

[0061] In the above implementation process, the second housing 21 is set in the shape of a square tube, which facilitates the peripheral part of the intercepting plate 23 inserted from the installation opening 211 on the side to be in close contact with the inner wall of the second housing 21, so that the air passing through the inside of the second housing 21 can be intercepted by the intercepting plate 23; after the intercepting plate 23 is inserted into the second housing 21 through the installation opening 211, its side edge can be tightly clamped in the installation groove 212, thus achieving firm fixation. This design not only simplifies the installation process of the intercepting plate 23, but also ensures its stability and reliability during operation. Importantly, since the intercepting plate 23 will be blocked after being used for a certain period of time, the method of inserting from the installation opening 211 on the side can facilitate its disassembly and replacement, extend the service life of the equipment, and ensure high dust removal efficiency.

[0062] Optionally, a detachable sealing cover plate 213 is installed at the position of the second housing 21 corresponding to the installation opening 211. The sealing cover plate 213 can be opened when the intercepting plate 23 needs to be disassembled and assembled, and the sealing cover plate 213 can be covered again after the intercepting plate 23 is installed to seal the installation opening 211, so that the internal air flow can only enter the water tank 4 after passing through the intercepting plate 23.

[0063] In some embodiments, referring to Figures 6-7 , the installation groove 212 includes a first limiting strip 2121 and a second limiting strip 2122 arranged at intervals. The first limiting strip 2121 is straight, and the second limiting strip 2122 includes a sliding-in section 21221 and a supporting section 21222 that form an angle with each other. The sliding-in section 21221 is arranged parallel to the first limiting strip 2121, and the distance between the sliding-in section 21221 and the first limiting strip 2121 is greater than the thickness of the intercepting plate 23. The supporting section 21222 inclines towards the direction where the first limiting strip 2121 is located relative to the sliding-in section 21221, and the distance between the end of the supporting section 21222 far from the sliding-in section 21221 and the first limiting strip 2121 does not exceed the thickness of the intercepting plate 23; a tightening screw 2123 is installed at one end of the sliding-in section 21221 far from the supporting section 21222, and the intercepting plate 23 is tightly pressed against the first limiting strip 2121 by jointly pressing the intercepting plate 23 with the supporting section 21222 and the tightening screw 2123.

[0064] In the above implementation process, the installation groove 212 includes a first limiting strip 2121 and a second limiting strip 2122 which are arranged at intervals. Among them, the innovative design of the second limiting strip 2122 is particularly crucial. The second limiting strip 2122 is composed of a sliding-in section 21221 and a supporting section 21222. The sliding-in section 21221 is parallel to the first limiting strip 2121 and the distance therebetween is greater than the thickness of the intercepting plate 23, facilitating the easy insertion of the intercepting plate 23. It is particularly worth mentioning that the supporting section 21222 inclines towards the first limiting strip 2121 and forms an angle with the sliding-in section 21221. The distance between the end of the supporting section 21222 far from the sliding-in section 21221 and the first limiting strip 2121 does not exceed the thickness of the intercepting plate 23. Such a design enables the intercepting plate 23 to be effectively supported and limited after insertion. In cooperation with the tightening screw 2123 threadedly installed at one end of the sliding-in section 21221 far from the supporting section 21222, by rotating the tightening screw 2123, the side of the intercepting plate 23 far from the supporting section 21222 can be further tightened. This structure not only compensates for the possible machining errors of the intercepting plate 23 but also greatly enhances the stability of the intercepting plate 23 after installation. Under the action of high-speed air flow, this fastening method can effectively prevent the intercepting plate 23 from vibrating, ensuring the overall performance and operation safety of the dust removal device. In summary, the refined design of the installation groove 212 in this solution not only simplifies the installation process of the intercepting plate 23 but also significantly improves the stability and reliability of the intercepting plate 23 in the working state.

[0065] Based on the above structure, when installing the intercepting plate 23 in this embodiment, the intercepting plate 23 is inserted into the installation groove 212 after aligning one end of the sliding-in section 21221. After pushing the intercepting plate 23 until it abuts against the supporting section 21222 and cannot be pushed further, the tightening screw 2123 is tightened to make it tighten the intercepting plate 23, so as to fix the frame of the intercepting plate 23 tightly against the first limiting strip 2121.

[0066] In some embodiments, the intercepting plate 23 is a chord grid plate or a wire mesh.

[0067] Specifically, the intercepting plate 23 is selected as a chord grid plate or a wire mesh, and these two products have significant advantages in the field of dust removal. The chord grid plate, with its unique structure, can effectively intercept large particulate dust in the air while allowing the air flow to pass through smoothly, reducing resistance. The wire mesh, with its dense mesh holes, can capture finer dust particles, improving the dust removal efficiency. Selecting the chord grid plate or the wire mesh as the material of the intercepting plate 23 not only meets the dust removal requirements of the vertical wet high-efficiency dust collector, but also can extend the service life of the intercepting plate 23 to a certain extent. This is because both of these materials have strong wear resistance and corrosion resistance and can maintain stable performance in harsh working environments. In addition, the installation and maintenance of the chord grid plate and the wire mesh are relatively simple. Through structural designs such as the above-mentioned installation groove 212 and the fastening screw 2123, rapid installation and disassembly can be achieved, facilitating the cleaning and replacement of the intercepting plate 23 and ensuring that the dust removal device always remains in the best working state.

[0068] In some embodiments, at least two parallel intercepting plates 23 are arranged in the second housing 21, and the ventilation holes on each intercepting plate 23 are arranged in a staggered manner.

[0069] Specifically, the arrangement of multiple intercepting plates 23 increases the length of the air dust removal path, enabling the dust-containing liquid droplets in the air to have more opportunities to come into contact with the intercepting plates 23 and be captured. At the same time, the staggered arrangement of the ventilation holes further disrupts the flow state of the air flow, making it more difficult for the dust-containing liquid droplets to escape in the air flow, thereby improving the dust removal efficiency.

[0070] Optionally, when a chord grid plate is adopted, the adjacent chord grid plates on both sides are arranged in a criss-cross manner to optimize the intercepting effect.

[0071] In some embodiments, referring to Figures 1-2 , the demisting and dehydration device 3 includes a third housing 31, a demisting baffle 32 and an exhaust hood 33. The demisting baffle 32 is arranged in an inverted V shape in the third housing 31, and the exhaust hood 33 is installed on the exhaust side of the third housing 31.

[0072] In the above implementation process, the demisting baffle 32 is designed in an inverted V shape, which can increase the demisting area of the demisting baffle 32, improve the demisting ability, and at the same time, the demisting baffle 32 can be inclined so that the air flow can fully impact the demisting baffle 32, making the demisting more efficient. Installing the exhaust hood 33 on the exhaust side of the third housing 31 can guide the air flow to horizontally disperse around, avoiding the air flow from blowing out concentratedly.

[0073] Among them, the exhaust hood 33 has a pavilion-like structure, which includes multiple support columns and a ceiling connected to the tops of the support columns. Ventilation openings are formed between the support columns to intercept the upwardly discharged gas by the exhaust hood 33 and guide it to disperse in all directions.

[0074] Optionally, referring to Figure 8 , a support angle steel 311 is provided in the third housing 31, and the edge of the demisting baffle 32 is fixed by the support angle steel 311 so that it maintains an inverted V shape in the third housing 31.
