Abstract
Description
Technical Field
[0001] The present invention relates to the field of industrial gas purification, and in particular to a device for collecting dust and soluble gas. Background Art
[0002] Industries prone to generating dust and soluble harmful gases, such as steel, cement, and glass manufacturing, as well as thermal power generation, kiln brick firing, and ceramic processing, all require environmentally friendly treatment of collected gases before discharge. Specifically, solid particles such as dust and dust particles mixed in the gases must be removed and recovered, and soluble pollutants such as sulfur dioxide and nitrogen oxides must be desulfurized and denitrified for environmentally friendly treatment.
[0003] Existing environmentally friendly gas treatment methods mostly rely on passing the gas through a solution for spraying to remove dust and water-soluble gases, then allowing solid particles to settle and remove slag. The sprayed water is then collected, pH-neutralized, and then discharged. However, these approaches fail to effectively remove dust and remove slag, and often require multiple stages of dust removal and water-soluble gas treatment, resulting in bulky and complex equipment and low gas treatment efficiency. Summary of the Invention
[0004] The purpose of the present invention is to provide a device for collecting dust and soluble gas to solve one or more technical problems existing in the prior art and at least provide a beneficial option or create conditions.
[0005] The technical solutions adopted to solve the above technical problems are:
[0006] A device for collecting dust and soluble gas, comprising a gas phase separation module, a diversion adsorption module, an exhaust module and a waste liquid collection module, wherein:
[0007] The gas phase separation module comprises:
[0008] A gas phase separation unit is provided in the first vent pipe, comprising: a disk disposed in the first vent pipe, the disk being disc-shaped as a whole, with any disk surface of the disk serving as a water-facing surface, the center of the water-facing surface being concave relative to the periphery of the disk, so that the water-facing surface forms at least one step, a plurality of radial notches are provided on the periphery of the disk, the central axis of the disk being parallel to the axial direction of the first vent pipe and the disk being rotatable about the central axis; and a first water supply device supplying water to the water-facing surface.
[0009] The split flow adsorption module comprises:
[0010] a second ventilation pipe, having a second inlet and a second outlet at both ends thereof, wherein the second inlet is connected to the first outlet;
[0011] an adsorption chamber located in the second ventilation pipe, wherein a guide grid layer is provided at one end of the adsorption chamber facing the second inlet, the guide grid layer including a plurality of guide ports, the guide ports being circumferentially distributed around the central axis of the second ventilation pipe, the adsorption chamber being in communication with the second inlet through the guide ports;
[0012] An adsorption unit having a plurality of mutually communicating air venting channels, wherein the air venting channels are in communication with the outside of the adsorption unit, and the second ventilation pipe is provided with a plurality of the adsorption units;
[0013] a second water supply device, which supplies water to the adsorption chamber;
[0014] The exhaust module is connected to the second outlet of the second ventilation pipe and is used to discharge the gas output from the second outlet; the waste liquid collection module is located below the gas phase separation module and the diversion adsorption module and is used to receive the liquid flowing down from the gas phase separation module and the diversion adsorption module.
[0015] It should be noted that the orientation characteristics of the adsorption chamber, such as the end thereof facing the second inlet, in the above technical solution are determined based on the flow direction of the gas to be treated. That is, regardless of whether the gas flow enters the adsorption chamber directly through a certain end after being blown into the second inlet, or whether the gas flow deflects and then enters the adsorption chamber from a certain end, the end of the adsorption chamber should be considered to be facing the second inlet.
[0016] The present invention has the following beneficial effects: during operation, the impeller rotates at high speed in the first ventilation pipe, and the water supplied by the first water supply device to the water-facing surface is flattened by the water-facing surface due to centrifugal force, and then thrown out along multiple radial notches to form radial jets. The steps on the water-facing surface further flatten the water surface and make it uniform. When the gas to be treated is introduced from the first inlet, and the airflow passes through the water curtain formed by the radial jets, the dust particles in the airflow are wrapped by the moist water mist and then thrown toward the inner wall of the first ventilation pipe together with the radial jets, and then settle and separate. At the same time, the rotating and radially centrifugal jets interact with the airflow, shearing into liquid micro-beads with high specific surface area. These liquid micro-beads dissolve the soluble components in the gas to be treated and encapsulate the dust particles. Therefore, after the gas to be treated exits the gas phase separation module, it has been significantly dust-removed and soluble gases have been removed, and is output as a mixed fluid with a uniform mixture of gas, liquid and dust. The mixed fluid passes through the second inlet, the guide opening of the guide grid layer, and then forms a multi-channel rotating evacuation mixed fluid, which is blown into the adsorption chamber. Since each adsorption unit has multiple ventilation channels that are interconnected, and the ventilation channels are connected to the outside of the adsorption unit, the rotating evacuated mixed fluid will shuttle turbulently in the complex and changeable multiple ventilation channels constructed by the adsorption unit. The second water supply device supplies water to the adsorption chamber, so that the adsorption chamber is filled with water mist. Due to the continuous changes in the flow direction and path, the liquid microbeads and some untreated soluble gases and dust in the rotating evacuated mixed fluid are adhered to the surface of the adsorption unit to form an attached fluid, which is combined with the sprayed water mist in the adsorption chamber and settles downward. Then, the clean air that has been freed of dust and soluble gases meets the environmental emission standards and is discharged through the second outlet under the action of the exhaust module; the waste liquid containing dust and dissolved soluble gases flowing from the gas phase separation module and the diversion adsorption module flows downward under the action of gravity and is received and recycled by the waste liquid collection module.
[0017] The present invention, within a limited space, cleverly designs the device structure so that the gas to be treated is first efficiently de-dusted and sheared into liquid micro-droplets and airflow by the gas phase separation module, forming a three-phase mixed fluid with uniform mixing in a short period of time. The fluid is then subjected to a swirl diversion by the diversion adsorption module, forming a complex and variable ventilation channel combination in the area composed of multiple adsorption units, extending the contact time between the mixed fluid and the adsorption unit, and increasing the collision contact force between the firmware and the fluid. After the fluid containing water mist and water droplets of dust exhaust gas is captured in the front and enters the tortuous path of the multi-channel, the adsorption unit absorbs and removes the water droplets and water mist. In this way, the mixed fluid is further subjected to dust removal, desulfurization and denitrification and other purification operations by physical means, and finally clean gas is discharged, dust is collected, and waste liquid is recovered. Unlike traditional gas environmental protection treatment methods that require large and complex multi-stage sedimentation and filtration devices and a large amount of chemical liquids for reaction, the overall structure is compact and easy to produce and operate. The present invention can be applied to waste gas treatment occasions.
[0018] In some embodiments, the first vent tube is arranged in an overall vertical direction. The overall vertical arrangement of the first vent tube facilitates the liquid ejected from the impeller disc to quickly flow downward along the inner wall of the tube after hitting the inner wall of the first vent tube. These liquids already contain most of the dust and dissolved toxic and harmful soluble gases. By arranging the first vent tube vertically, the liquids can flow downward quickly and avoid re-mixing with the gas that has already been purified by the radial jet of the impeller disc. In addition, because the impeller disc rotates at high speed and is mostly driven by a waterproof motor, and the central water supply provided by the first water supply device needs to be flattened and spun out, the impeller disc may cause vibrations with a certain impact. Arranging the first vent tube in a vertical direction will utilize the structural stability of the vertically arranged cylinder, reduce the vibration amplitude of the impeller disc, produce a better and more uniform gas purification effect, and extend the service life of the components.
[0019] In some embodiments, a fixed bracket is provided within the first vent tube, and a waterproof motor is mounted on the fixed bracket. The spinning disc is connected to the waterproof motor, and the central axis of the spinning disc is coaxial with the first vent tube. The fixed bracket, in conjunction with the waterproof motor, directly drives the spinning disc to rotate, reducing the number of transmission components, making the overall structure more compact, and facilitating the centering of the spinning disc. The coaxiality of the central axis of the spinning disc with the first vent tube ensures that the jet water curtain created by the spinning disc has a reasonable range and uniform coverage. The central placement avoids severe eccentric vibration and provides a more stable structure.
[0020] In some embodiments, with the first inlet of the first ventilation pipe facing upward, the center of the water-facing surface is concave to form a water receiving chamber, and the water-facing surface forms two or more steps from the edge of the water receiving chamber to the periphery of the spinner, and the steps have a smooth transition. The spinner has a plurality of protrusions arranged in an equidistant array around the circumference, and the gap between two adjacent protrusions is the radial notch; the first water supply device includes a first water supply pipe that can be connected to an external water source, and the outlet of the first water supply pipe is facing the center of the water receiving chamber.
[0021] The water output from the outlet of the first water supply pipe falls in the center of the water receiving chamber, and the spinner rotates at a high speed. The water in the water receiving chamber is pulled by centrifugal force and quickly diffuses to the periphery of the spinner on the water-facing surface. Since the water-facing surface forms more than two steps and the steps have a smooth transition, the water in the center needs to continuously climb more than two steps before diffusing to the periphery of the spinner, thereby reducing the unnecessary splashing of the water flow to a certain extent, making the water spread as flat as possible and close to the water-facing surface to form a water film, thereby increasing the contact area with the gas and better intercepting the gas to be treated; the gap between the protrusions is used as a radial notch, so that the spinner is easy to process and manufacture, and the width and position of the radial notch can be convenient for later processing, modification and adjustment.
[0022] In some embodiments, the second vent pipe is arranged in a vertical direction as a whole. Since a large number of adsorption units are filled in the second vent pipe, and the multiple inclined guide ports of the guide grid layer will force the gas to be treated to form multiple channels of rotating evacuated mixed fluid to fully contact the adsorption units, and then cooperate with the water supply spray of the second water supply device, the vertically arranged second vent pipe can make the mixed fluid blow upward as a whole in a humid environment. The adsorption units have a tendency to move downward due to their own weight. The upward wind force of the mixed fluid will blow interactively in the multiple channels formed by the adsorption units, which is conducive to the full contact and interaction between the adsorption units and the mixed fluid. In addition, if the adsorption units are relatively light and few, the adsorption units may collide in a disorderly manner in the second vent pipe. The vertical arrangement of the second vent pipe is conducive to the stability of the pipe. In addition, the fluid attached to the surface of the adsorption unit and the water supplied to the adsorption chamber by the second water supply device can naturally flow downward. The inner wall of the vertically arranged second vent pipe can provide a favorable drainage guide for this.
[0023] In some embodiments, a barrier structure for preventing the adsorption unit from detaching from the second outlet is provided at the second outlet, and the barrier structure has multiple exhaust ports; the second water supply device includes a second water supply pipe that can be connected to an external water source, and the second water supply pipe has multiple spray ports located at the second outlet. Since the second outlet is provided with a barrier structure, combined with the guide grid layer provided at the second inlet, the adsorption unit can be confined as a whole within the second ventilation pipe, and there is no need to worry about the adsorption unit being dislodged due to excessive wind. The spray ports provided in the second water supply pipe will spray the adsorption unit group in the adsorption chamber, creating a more uniform water mist, which is conducive to driving the rotating evacuation of the mixed fluid and adsorption and fluid sedimentation on the surface of the adsorption unit.
[0024] In some embodiments, the adsorption chamber is provided with at least two guide grille layers, so that the adsorption chamber is divided into at least two cavities along the central axis direction of the second ventilation pipe, and a plurality of the adsorption units are located in the cavities. This divides the adsorption chamber into multiple layers, so that the adsorption unit groups between each cavity are relatively independent, reducing the chance of repeated contamination. And the number and presence of adsorption units in individual cavities can be selected according to actual conditions, making the application more flexible. In addition, the cavity here is not limited to whether it is completely closed. For example, assuming that the second ventilation pipe is in a vertical position, the adsorption chamber is provided with two guide grille layers in sequence from bottom to top. Then the cavity below may be relatively closed, while the cavity above may be relatively open, but both can be filled with adsorption units without affecting the work.
[0025] In some embodiments, the guide grid layer includes:
[0026] a central column coaxial with the second vent tube;
[0027] There are multiple guide plates, which are distributed equidistantly around the central column. Each guide plate is inclined relative to the radial plane of the central column and the guide plate as a whole extends radially along the second ventilation pipe. The guide plate has a first connecting end and a second connecting end. The first connecting end is connected to the outer periphery of the central column, and the second connecting end is connected to the inner tube wall of the second ventilation pipe. The guide port is defined between two adjacent guide plates, and the width of the second connecting end is greater than the width of the first connecting end.
[0028] The central column and the guide plate form a wind wheel grille that is approximately multi-blade. Because the width of the second connecting end of the guide plate is greater than the width of the first connecting end, the guide port forms a specific structure with an uneven guide distance of short in the center and long at the outer end. The airflow sent out through the guide port is easily guided by the guide effect of the guide port to form a cyclone airflow with uneven wind speed around the circle, which is conducive to the agitation and blowing of the airflow, so that the mixed airflow is fully in contact with the adsorption unit, rather than relying solely on wind force to blow away the adsorption unit, resulting in only the action of blowing away the adsorption unit but not much contact and attachment dust and liquid removal effect.
[0029] In some embodiments, the guide grid layer further comprises:
[0030] An inner ring, which is annular as a whole and is provided between the first connecting end and the second connecting end, and the inner ring connects the guide plates in the guide grid layer;
[0031] The outer ring is annular in shape as a whole and is located at the periphery of the guide grid layer. The outer ring is connected to each second connection end in the guide grid layer and is fixedly connected to the inner tube wall of the second ventilation pipe.
[0032] The inner ring and the outer ring reinforce the structure of the guide grid layer and further guide the airflow so that it forms multiple airflows that enter the adsorption chamber and come into contact with the airflow channels of the adsorption unit.
[0033] In some embodiments, the adsorption unit comprises:
[0034] an equatorial ring, having a plurality of wind holes thereon and a central axis;
[0035] a plurality of first adsorption plates, each of which is equidistantly and radially distributed around the central axis of the equatorial ring, with a normal direction of the surface where the equatorial ring is located as the upper side relative to the first adsorption plates; and each of the first adsorption plates is located above the equatorial ring, and the upper portions of the first adsorption plates gradually converge and are connected together by a first polar ring;
[0036] A plurality of second adsorption plates are provided, each of which is equidistantly spaced and radially distributed around the central axis of the equatorial ring. The second adsorption plates are all located below the equatorial ring, and the lower portions of the second adsorption plates gradually converge and are connected together by a second polar ring. In the circumferential direction, any second adsorption plate is located between two adjacent first adsorption plates;
[0037] The empty spaces between the equatorial ring, the first adsorption plate, the second adsorption plate, the first pole ring, and the second pole ring constitute the wind-dispersing flow channel.
[0038] The structure of the above-mentioned adsorption unit makes the adsorption unit as a whole approximately spherical, and the equatorial ring, the first adsorption plate, the second adsorption plate, the first pole ring, and the second pole ring are connected to form a skeleton with a large number of empty positions, which can constitute the air-dispersing flow channel, so that the surface area of the firmware within the unit volume is greatly increased, which is conducive to contact adsorption; with the equatorial ring as the latitude direction, the first adsorption plate and the second adsorption plate as the plate body in the longitude direction, which are easily blown by the airflow, causing the adsorption unit to roll and rotate, and then the spatial position of the air-dispersing flow channel changes, and a new flow channel structure is reconstructed, so that the airflow shuttle path becomes tortuous, complex and lengthy, thereby increasing the chance of adsorption. In the circumferential direction, any second adsorption plate is a structural setting located between two adjacent first adsorption plates, so that the adsorption unit does not form a continuous long gap in the longitude direction. In this way, during the tumbling and rotation of multiple adsorption units, the first or second adsorption plates between different adsorption units will not be nested in the long gap, causing the adsorption units to be entangled together and unable to rotate smoothly. In addition, this structure not only ensures that the windward plate surface is large and easy to adsorb and prevents the units from nesting with each other, but also saves materials and is easy to manufacture.
[0039] In some embodiments, the exhaust module comprises:
[0040] a primary filter chamber located at an upper portion of the barrier structure, the primary filter chamber being in communication with the adsorption chamber;
[0041] a secondary filter chamber, which is connected to the primary filter chamber, and a partition is provided at the connection position;
[0042] An air outlet duct comprising an upper inlet and a lower outlet, wherein the upper inlet is located at a higher vertical height than the lower outlet, and the upper inlet is connected to the secondary filter chamber;
[0043] The negative pressure exhaust device has a cavity shell that can generate negative pressure exhaust, the cavity shell is connected to the lower outlet, and the cavity shell is provided with an exhaust port connected to the outside.
[0044] The negative pressure generated by the chamber draws the entire system's treated gas through the gas phase separation module and the diverter adsorption module, then into the primary filter chamber. From there, it enters the secondary filter chamber and exits the exhaust duct, ultimately exiting through the exhaust port. The primary and secondary filter chambers provide two resting barriers for the gas after passing through the diverter adsorption module. This mitigates turbulence to some extent, facilitating smoother discharge. Furthermore, the screens provide additional filtering, trapping dust, oil droplets, and other debris that may have been accidentally absorbed, settled, or blown away by the preceding modules. The primary and secondary filter chambers also redirect the airflow, ensuring smoother flow into the exhaust duct. The upper inlet of the exhaust duct is higher than the lower outlet, forcing the airflow into a downward motion. This helps settle liquid particles and adhere to the duct walls, resulting in cleaner exhaust gas. Any adherence to the duct walls can be dealt with by cleaning the duct at a later time. In some cases, other substances such as activated carbon and adsorbent cotton that are beneficial for gas filtration can be added to the primary and / or secondary filter cavities to improve space utilization and enhance gas purification effectiveness. The overall structural layout of the exhaust module utilizes the height difference between itself and the gas phase separation module and the diversion adsorption module, making the structure of the present invention more compact and occupying less space.
[0045] In some embodiments, the waste liquid collection module includes a funnel cavity, the upper part of the funnel cavity is connected to the first outlet and the second inlet at the same time, and the lower part of the funnel cavity is gradually narrowed and is provided with a waste liquid outlet located at the lower end of the funnel cavity. Since the upper part of the funnel cavity is connected to the first outlet and the second inlet at the same time, the gas will first pass through the funnel cavity after being sent out from the first outlet, and then enter the second ventilation pipe from the second inlet. At this time, the funnel cavity plays a role of load-bearing transition, and the waste liquid flowing from the gas phase separation module and the diversion adsorption module, such as droplets containing dust and spray water dissolved in soluble gas, will gradually gather downward along the cavity wall of the funnel cavity and finally be discharged from the waste liquid outlet, leaving it to be processed by other waste liquid treatment procedures. Specifically, the waste liquid collection module is located directly below the gas phase separation module and the diversion adsorption module, which further reduces the footprint of the device and makes the structure more compact.

[0055] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

Greater than, less than, and exceed are understood as not including the number itself, and above, below, and within are understood as including the number itself.
[0058] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0059] Reference Figures 1 to 6 , several embodiments of the present invention are given below.
[0060] A device for collecting dust and soluble gas includes a gas phase separation module, a diversion adsorption module, an exhaust module and a waste liquid collection module. The gas to be treated is input from the first inlet of the gas phase separation module, passes through the gas phase separation module and the diversion adsorption module, and is discharged to the outside from the exhaust port of the exhaust module.
[0061] In some embodiments, the gas phase separation module includes a first ventilation pipe 100, and a first inlet and a first outlet are respectively provided at both ends of the first ventilation pipe 100. At least one gas phase separation unit is provided in the first ventilation pipe 100, and the gas phase separation unit includes a spinner 101 and a first water supply device. The spinner 101 is generally disc-shaped, and any disk surface of the spinner 101 is used as the water-facing surface. The center of the water-facing surface is concave relative to the periphery of the spinner 101 so that the water-facing surface forms at least one step. A plurality of radial notches are provided around the periphery of the spinner 101, and these radial notches are circumferentially spaced around the central axis of the spinner. The central axis of the spinner 101 is coaxial with the first ventilation pipe 100, and the first water supply device supplies water to the water-facing surface. Specifically, in some embodiments, the first ventilation pipe 100 is vertically arranged, and the upward end of the first ventilation pipe 100 serves as the first inlet, and the downward end serves as the first outlet. The central axis of the spinner 101 is collinear with the central axis of the first ventilation pipe 100, so that the spinner 101 is in a horizontal position as a whole. For example, if only one gas phase separation unit is provided, the upward side of the spinner 101 can be used as the water-facing side. When the first water supply device located near the first inlet pours water downward, the water is poured into the center of the water-facing surface, and the impeller 101 rotates at high speed, throwing the water on the water-facing surface away in the circumferential direction, and finally throwing it out through the radial notch, forming a high-speed rotating shear water curtain, which shears and decomposes the gas to be treated that enters the first ventilation pipe 100 from the first inlet, forming droplets that encapsulate dust and dissolve a considerable portion of soluble gas, and then flows down along the vertical pipe wall of the first ventilation pipe 100 for recovery. After passing through this gas phase separation path, the gas to be treated becomes much cleaner, and is then output from the first outlet and advances to the next stage. In some other embodiments, more than two gas phase separation units can also be provided, that is, the number of impellers 101 can be more than two, as long as there is a device to supply water to the water-facing surface of the corresponding impeller 101 and rotate with each other to form a shear water curtain. The water-facing surfaces of these spinning discs 101 can be in the same direction or in opposite directions. For example, the water-facing surface of one spinning disc 101 faces upward, and the water-facing surface of the other spinning disc 101 faces downward. They are coaxially installed and driven by a motor to rotate in the same or opposite directions.
[0062] Of course, in other embodiments, the first vent pipe 100 may also be set to other postures, such as horizontal or tilted. Because under the effect of gravity, the liquid that hits the inner wall of the pipe will always flow downward and be recovered, so the effect of gas phase separation, purification of dust and soluble gas can all be brought into play. In addition, in order to make the structure more compact, a fixed bracket can be directly set inside the first vent pipe 100, a waterproof motor 103 can be connected on the fixed bracket, and the output shaft of the waterproof motor 103 can be connected to the disk 101, and specifically a reduction gear can be added on the connection path of the waterproof motor 103 and the disk 101 depending on the situation. If the waterproof motor 103 is set outside the first vent pipe 100, then by introducing other transmission structures, through the tube wall or winding around from other positions, then the disk 101 can be dragged to rotate.
[0063] In some embodiments, the impeller 101 is provided with at least two steps extending from the center of its water-facing surface toward its circumference, with the steps having smooth transitions at the edges. That is, if the center of the water-facing surface is recessed to form a water receiving chamber, the water injected into the water-injection chamber, under the centrifugal force of the impeller 101's rotation, will first climb a step, then advance toward the circumferential edge, then climb a higher step, then advance toward the circumferential edge again, and so on, until it reaches the radial notch and is ejected. The reason the water climbs multiple steps is to spread the water out onto the water-facing surface, forming a water film and reducing excessive kinetic energy. This prevents the water from becoming a randomly splashing mist under high-speed rotation, preventing it from effectively reaching the radial notch to form a radial jet, thereby failing to block the gas being blown toward the water-facing surface. The number and height of the steps should be determined based on factors such as the size of the impeller 101. The water receiving cavity and the step of the swing plate 101 can be formed by boring a single or double-sided casting blank, or by machining a thick piece after casting, or by stamping a thin-walled sheet metal part.
[0064] In certain embodiments, the peripheral circumference equidistant array of the described disk 101 has a plurality of projections 102, and the gap between two adjacent projections is as the described radial gap.It should be pointed out that the described projections 102 may not necessarily be equal in size.In certain embodiments, the whole sizes of the projections 102 are equal, that is, the width of the described radial gap is equal.And in other embodiments, the projections 102 can be made unequal in size, for example, between two large projections, a plurality of small projections are set, which is equivalent to increasing a plurality of small gaps between a large radial gap. Of course, at this time, the principle of circumferential symmetry and equidistant distribution should also be followed to avoid the disk 101 center of gravity from shifting. This arrangement of multiple small gaps between the large radial gaps allows the radial jets ejected by the spinner 101 to form a water curtain bundle that is uneven in thickness in the circumferential direction but symmetrical and uniform overall. This is conducive to faster drainage of water per unit time, guiding the jets to rush toward the inner wall of the first ventilation pipe 100, reducing the excess liquid in the water receiving chamber, and reducing the excess water that is not ejected and has to flow freely but does not participate in gas purification, thereby improving work efficiency.
[0065] In some embodiments, the diversion adsorption module includes a second ventilation pipe 200, and a second inlet and a second outlet are respectively provided at both ends of the second ventilation pipe 200. An adsorption chamber is formed inside the tube of the second ventilation pipe 200, and a guide grid layer 301 is provided at one end of the adsorption chamber facing the second inlet. A plurality of adsorption units 500 are filled in the adsorption chamber, and a guide port 302 is provided on the guide grid layer 301. The diversion adsorption module is also provided with a second water supply device that supplies water to the adsorption chamber. The waste liquid collection module connects the first outlet with the second inlet. The gas output from the first outlet passes through the waste liquid collection module and is input from the second inlet. After passing through the guide port 302, it enters the adsorption chamber. The second water supply device sprays water into the adsorption chamber to form a moist space in the adsorption chamber. The gas entering the adsorption chamber blows the adsorption unit 500 to rotate and tumble. The dust droplets and water droplets dissolved in other soluble gases in the gas fully contact and adhere to the adsorption unit 500, and then flow downward under the action of gravity and are finally recovered. The purified air is discharged from the second outlet. Specifically, the second ventilation pipe 200 is placed vertically as a whole. At this time, the second inlet is facing downward and the second outlet is facing upward. The component located below is the guide grille layer 301, which is equivalent to a supporting member, so that the second ventilation pipe 200 is a barrel with a hollow bottom, which accommodates multiple adsorption units 500. At this time, the bottom layer of the adsorption chamber is the guide grid layer 301, the side cavity wall of the adsorption chamber is the inner wall of the second ventilation pipe 200, and the top of the adsorption chamber is relatively open. When the wind is not very strong or the adsorption unit 500 has a relatively large mass, the airflow will not blow the adsorption unit out of the second ventilation pipe 200, so the equipment can operate safely. To improve safety and facilitate the addition of other components, in some embodiments, a blocking structure is provided at the second outlet to prevent the adsorption unit 500 from detaching from the second outlet. The blocking structure has multiple exhaust ports. More specifically, in some embodiments, the blocking structure is a grid 400 covering the second outlet.
[0066] The number of guide grid layers 301 is not limited to one; multiple layers can be provided along the second vent tube 200. Therefore, by providing multiple layers of guide grid layers 301, the adsorption chamber can be vertically divided into multiple layers of cavities, with the top cover of the topmost layer of cavities forming the barrier structure. Each layer of cavities is populated with multiple adsorption units 500, with the number and specifications determined based on the specific application. Some cavities may also be left empty.
[0067] In some embodiments, the guide grid layer 301 is structured as follows: it includes a central column 303 and guide plates 304. The central column 303 is coaxial with the second ventilation tube 200, that is, when the second ventilation tube 200 is vertically arranged, the central column 303 is also vertical. The guide plates 304 are generally straight and have a first connecting end and a second connecting end. The first connecting end is slightly smaller in width than the second connecting end. The first connecting end is connected to the side wall of the central column 303. The guide plates 304 are inclined relative to the horizontal plane, and the second connecting end is connected to the inner wall of the second ventilation tube 200. Multiple guide plates 304 are evenly spaced around the central column 303, and the guide opening 302 is defined between adjacent guide plates 304. Of course, to prevent the adsorption unit 500 from falling, the width of the guide opening 302 should be smaller than the outer diameter of the adsorption unit 500. More specifically, to enhance structural strength and facilitate installation, in some embodiments, the guide grille layer 301 is further provided with an inner ring 305 and an outer ring 306. The inner ring 305 and outer ring 306 are concentric circular rings concentric with the center column 303. The outer ring 306 is connected to the second connection end of the guide plate 304, while the inner ring 305 is connected to the middle portion of the guide plate 304. The outer ring 306 is fixed to the inner wall of the second ventilation pipe 200, that is, the second connection end is connected to the inner wall of the second ventilation pipe 200 via the outer ring 306. The guide grille layer 301 is shaped similar to a fan blade. The annularly distributed, inclined guide ports 302 formed therein guide the airflow entering and exiting from below and then blowing out from above the guide ports 302 to form a rotating, dispersed mixed fluid. This cyclonic airflow, combined with the water mist sprayed down by the second water supply device, enables the adsorption unit 500 to achieve excellent adsorption and purification effects. Of course, the invention does not limit the shape and structure of each layer of the guide grille layer 301 to be equal. Under the premise of ensuring the cleaning effect, it is allowed to make adaptive changes to each layer of the guide grille layer 301 according to actual conditions, such as adding or removing guide plates 304, adjusting the inclination of the guide port 302, or adding a grid in the cavity, etc.
[0068] In some embodiments, the adsorption unit 500 includes an equatorial ring 501, a first adsorption plate 502, a second adsorption plate 504, a first polar ring 503, and a second polar ring 505. With reference to the longitude and latitude of a conventional sphere, the equatorial ring 501 is located in the middle, dividing the adsorption unit 500 into a northern hemisphere and a southern hemisphere. The first polar ring 503 is located at the top of the northern hemisphere, and the second polar ring 505 is located at the bottom of the southern hemisphere. The first adsorption plate 502 is located in the northern hemisphere and has an overall shape of a right triangle with an arc-shaped hypotenuse. The upper and lower right-angled sides connect the first polar ring 503 and the equatorial ring 501, respectively. The second adsorption plate 504 is located in the southern hemisphere and has an overall shape of a right triangle with an arc-shaped hypotenuse that matches the arc of the first adsorption plate 502. The upper and lower right-angled sides connect the equatorial ring 501 and the second polar ring 505, respectively. The first adsorption plates 502 and the second adsorption plates 503 are equidistantly spaced radially around the central axis of the equatorial ring 501. In the circumferential direction, any second adsorption plate 504 is located between two adjacent first adsorption plates 502, meaning that the first adsorption plates 502 and the second adsorption plates 503 are located on different meridians. More specifically, in some embodiments, the equatorial ring 501 has three equatorial rings 501 from the outside to the inside, all located on the equatorial plane of the adsorption unit 500. These three equatorial rings 501 are connected to the first adsorption plate 502 and the second adsorption plate 503. The equatorial ring 501 is provided with a plurality of air holes, which are arranged in a circular array with equal spacing around the center of the equatorial ring 501. The multiple equatorial rings 501 enhance the overall strength of the adsorption unit 500, preventing structural damage caused by the variable tangential stresses generated by the repeated rotation and tumbling of the adsorption unit 500 in situations where wind speed is too strong and the material is relatively light.
[0069] The adsorption unit 500 has a spherical skeleton. The spaces between the structures serve as ventilation channels, allowing airflow to flow through in an unordered manner. The first adsorption plate 502 and the second adsorption plate 503 have a large windshield area, increasing the adsorption unit 500's contact with the gas. In areas where a large number of adsorption units 500 are stacked, a complex network of channels inevitably forms, facilitating the adhesion and convergence of droplets, ultimately allowing them to flow and be recovered under the influence of the spray water. The multi-layer equatorial ring 501 strengthens the adsorption unit 500 structure. The multiple ring structures at the top, middle, and bottom, combined with the spacing of the adsorption plates, facilitate smoother gas flow in the ventilation channels. The design of the ventilation holes reduces the weight of the adsorption unit 500. The staggered arrangement of the second adsorption plate 503 and the first adsorption plate 502 in the northern and southern hemispheres ensures that even if the two adsorption units 500 collide with each other, the long gaps will not cause the plates to become stuck and entangled, hindering rotation and tumbling. The reason is that, assuming that the two adsorption units 500 that collide are unit A and unit B, respectively, and taking the structures that have a nesting tendency with each other as the first adsorption plates 502 as an example, the convex arc edge of any first adsorption plate 502 on unit A can only be nested and cut into the gap between the two adjacent first adsorption plates 502 on unit B at most. However, due to the obstruction of the first polar ring 503 and the equatorial ring 501, the width of the gap between the plates will no longer allow the arc edge to be further cut into, so that the structure meets the technical requirements of ensuring that the windshield area is large enough, the wind flow channel is smooth and accessible, and can prevent each other from nesting. The blocking and nesting principles of other structural parts of the adsorption unit 500 are similar to the above analysis. Of course, in order to make the adsorption unit 500 easy to fill and replace, the adsorption unit 500 can be made of lightweight plastic.
[0070] In some embodiments, the first water supply device and the second water supply device share the same main water supply system. Figure 1 A main water pipe is introduced from the outside of the invention, and then branches out into a first side branch 801 and a second side branch 802. The first side branch 801 bends and extends into the upper part of the first ventilation pipe 100 and finally faces the spinner 101 to realize water supply. The second side branch 802 bends to the top of the second ventilation pipe 200, and is provided with multiple tributaries and a spray head to realize spraying the adsorption chamber from top to bottom.
[0071] For the waste liquid collection module, in some embodiments, the first ventilation pipe 100 is arranged next to the second ventilation pipe 200, and both are vertical, so that the first outlet and the second inlet are both facing downward. At this time, a funnel cavity 700 with a large opening facing upward and a small opening facing downward is provided below the first ventilation pipe 100 and the second ventilation pipe 200. The first outlet and the second inlet are simultaneously enclosed by the funnel cavity 700. In this way, the dissolved liquid droplets mixed with dust and soluble gas flowing out of the first ventilation pipe 100 and the second ventilation pipe 200 will fall into the funnel cavity 700 and be recovered from the waste liquid outlet 701 at the lower end of the funnel cavity 700, and the first outlet and the second inlet are also connected together. In other embodiments, the first vent pipe 100 is located below the second vent pipe 200, with the first inlet of the first vent pipe 100 facing downward and the first outlet facing upward. In this way, the gas output from the first vent pipe 100 will directly enter the second inlet, and then pass through the diversion port into the adsorption chamber. Since the spinner 101 rotates at high speed, even if the water-facing side faces downward, the purification effect will not be greatly affected. In this case, it is only necessary to locate the funnel chamber 700 below the first vent pipe 100 to simultaneously collect the waste liquid flowing from the first vent pipe 100 and the second vent pipe 200. In practice, the present invention may also include an eddy path sedimentation tank or a multi-compartment sedimentation tank, as well as a water pump, so that the waste liquid collected by the funnel chamber 700 can be directed to the eddy path sedimentation tank or the multi-compartment sedimentation tank, thereby subjecting the solid particles in the waste liquid to sedimentation and separation treatment. A water pump is then provided to recycle the separated water and connect it to the main water supply system.
[0072] In some embodiments, the exhaust module includes a first-level filter chamber 601 located at the upper part of the barrier structure, the first-level filter chamber 601 is connected to the adsorption chamber, and a second-level filter chamber 602 connected to the first-level filter chamber 601 is provided next to the first-level filter chamber 601, and a partition is provided at the connection position, and an opening is opened on the side of the second-level filter chamber 602, which is connected to the upper inlet of the outlet pipe 600, and the outlet pipe 600 is provided with a lower outlet after extending downward, and the lower outlet is connected to a negative pressure exhaust device. Through the negative pressure formed by the negative pressure exhaust device, the gas to be treated entering from the first ventilation pipe 100 passes through the gas phase separation module, the waste liquid collection module, the diversion adsorption module, the first-level filter chamber 601, the second-level filter chamber 602, and the outlet pipe 600, and then enters the negative pressure exhaust device and is finally discharged to the outside from the exhaust port of the cavity shell of the negative pressure exhaust device. When discharged, the gas to be treated has been purified and becomes a gas that meets environmental emission standards. The chamber shell 603 is configured as a vertical chamber, which has an upward exhaust port 604 that connects the chamber shell 603 to the outside world. A rain shield is provided above the exhaust port 604 to prevent external debris and rainwater from splashing into the chamber shell 603 from the exhaust port 604. An exhaust motor 605 is provided on the side of the chamber shell 603. The exhaust motor 605 drives the wind wheel provided in the chamber shell 603 to rotate through a belt transmission device, thereby generating a negative pressure in the chamber shell 603, pulling the gas to be treated input from the first inlet to advance along the aforementioned path. In order to save space, the primary filter chamber 601 and the secondary filter chamber 602 can both be made into a square cabinet with multiple cover plates spliced together, supported by some brackets, and mounted on the second ventilation pipe 200. The waste liquid collection module can also be made into a flat and long cabinet, which is provided below the gas phase separation module and the diversion adsorption module. Two connection ports are provided on the top of the flat and long cabinet, which are respectively connected to the first outlet and the second inlet. The funnel cavity 700 or the extended wall of the funnel cavity 700, the side wall of the second ventilation pipe 200, the side wall of the primary filter cavity 601, and the side wall of the secondary filter cavity 602 can be selectively provided with a detachable observation window to facilitate the understanding of the changes in the contents of the enclosed area at any time and to facilitate internal operations.
