The arrangement of the primary filter cavity and the secondary filter cavity ensures that the gas has two intermittent barriers after passing through the shunt adsorption module, on one hand, the turbulent flow state of the gas can be relieved to a certain extent, so that the gas can be smoothly discharged, on the other hand, the separation net can further assist in filtration, and the separation net can separate dust oil drops or other sundries needing to be separated, which are not adsorbed and settled or blown away by the front module due to accidents. In addition, the first-stage filter cavity and the second-stage filter cavity also play a role in redirecting airflow, so that the airflow smoothly enters the air outlet pipe.

The utility model provides a collect dust and soluble gaseous device, includes gaseous phase separation module, reposition of redundant personnel adsorption module, exhaust module and waste liquid collection module, pending gas is followed the first entry input of gaseous phase separation module is discharged to the external world from exhaust module's air exit behind gaseous phase separation module, the reposition of redundant personnel adsorption module.

In some embodiments, the gas phase separation module includes a first vent pipe 100, a first inlet and a first outlet are respectively disposed at two ends of the first vent pipe 100, at least one gas phase separation unit is disposed in the first vent pipe 100, the gas phase separation unit includes a throwing disk 101 and a first water supply device, the throwing disk 101 is integrally disk-shaped, any disk surface of the throwing disk 101 serves as a water facing surface, the center of the water facing surface is recessed relative to the periphery of the throwing disk 101 so that the water facing surface forms at least one step, a plurality of radial notches are disposed on the periphery of the throwing disk 101, the radial notches are circumferentially distributed at intervals around the central axis of the throwing disk, the central axis of the throwing disk 101 is coaxial with the first vent pipe 100, and the first water supply device supplies water to the water facing surface. Specifically, in some embodiments, the first vent pipe 100 is vertically disposed, such that an upward end of the first vent pipe 100 serves as a first inlet, a downward end serves as a first outlet, and a central axis of the flail plate 101 is collinear with an inner central axis of the first vent pipe 100, so that the flail plate 101 is in a horizontal posture as a whole. Taking the case of only one gas phase separation unit, the upward side of the throwing disk 101 may be used as the upstream side. When a first water supply device arranged near a first inlet injects water downwards, the water is injected to the central position of the upstream face, the throwing disc 101 rotates at a high speed, the water on the upstream face is thrown away in the circumferential direction and finally is thrown out through the radial gap to form a shearing water curtain rotating at a high speed, the gas to be treated introduced into the first vent pipe 100 from the first inlet is sheared and decomposed to form liquid drops which wrap dust and dissolve a part of soluble gas, and then the liquid drops flow downwards along the vertical pipe wall of the first vent pipe 100 for recovery. In other embodiments, more than two gas phase separation units may be provided, i.e. the number of throwing discs 101 may be more than two, as long as the device is ensured to supply water to the upstream face of the corresponding throwing disc 101, rotating with each other to form a shear water curtain. The water-facing surfaces of the flail disks 101 can be in the same direction or in opposite directions, for example, the water-facing surface of one of the flail disks 101 faces upwards, the water-facing surface of the other flail disk 101 faces downwards, and the flail disks are coaxially arranged with each other and driven to rotate in the same direction or in opposite directions by a motor.

Of course, in other embodiments, it is possible to set the first snorkel 100 in other positions, such as horizontal or inclined. Under the action of gravity, the liquid impacting on the inner wall of the pipe can flow downwards all the time to be recovered, so that the functions of gas phase separation, dust purification and soluble gas purification can be exerted. In addition, in order to make the structure more compact, a fixing bracket may be directly disposed inside the first ventilation pipe 100, a waterproof motor 103 is connected to the fixing bracket, and an output shaft of the waterproof motor 103 is connected to the flail disc 101, and specifically, a reduction gear is optionally added on a connection path between the waterproof motor 103 and the flail disc 101. If the waterproof motor 103 is arranged outside the first air pipe 100, other transmission structures can be introduced to penetrate through the pipe wall or wind from other positions, and then the flail disc 101 is dragged to rotate.

In some embodiments, the throwing disk 101 is provided with at least two steps from the center of the upstream surface to the circumference of the throwing disk 101, and the edges of the steps are in smooth transition. That is, if the center of the upstream surface is recessed to form a water receiving cavity, the amount of water injected into the water injection cavity first climbs over a step, then advances toward the circumferential edge, then climbs over a step higher than the step, and then advances toward the circumferential edge under the action of the centrifugal force of the rotation of the throwing disc 101, and so on until reaching the position of the radial notch, and then is thrown out. The water quantity is made to climb over the multistage steps, so that the water quantity is flattened on the upstream surface to form a water film, the excessive kinetic energy is weakened, the water quantity is not easy to be changed into water mist which splashes in a mess under the state of high-speed rotation and cannot effectively reach the radial gap to form radial jet flow, and therefore the gas to be treated blown against the upstream surface cannot be blocked. Of course, the number and height of the steps should be set according to the size of the flail plate 101 and other specific factors. The water receiving cavity and the steps of the throwing disc 101 can be formed by boring a single face or double faces of a blank through a casting, can be formed by machining after casting a uniform-thickness part, and can also be formed by punching a thin-wall sheet metal part.

In some embodiments, the periphery of the flail disk 101 is provided with a plurality of protrusions 102 in an equidistant array, and the radial gap is formed by a gap between two adjacent protrusions. It is noted that the bumps 102 do not necessarily have to be each equally large. In some embodiments, the bumps 102 are all of equal size, i.e., the radial notches are of equal width. In other embodiments, the projections 102 may be made non-uniform, for example, a plurality of small projections are disposed between two large projections, which is equivalent to a plurality of small notches are added between one large radial notch, and of course, the principle of circumferentially symmetric and equidistant distribution should be followed at this time to avoid the center of gravity of the flail plate 101 from shifting. The arrangement form of arranging the plurality of small gaps among the large radial gaps can lead the radial jet flow thrown out by the throwing disc 101 to have water curtain cluster which is uneven in thickness in the circumferential direction but symmetrical and uniform as a whole, is beneficial to leading water yield more quickly in unit time, leads the jet flow to impact the inner wall of the first breather pipe 100, reduces surplus liquid in the water receiving cavity, leads the surplus water which is not thrown out but only freely flows but does not participate in purified gas to be reduced, and improves the working efficiency.

Specifically, the second vent pipe 200 is vertically arranged, the second inlet is downward, the second outlet is upward, and the lower part is the flow guide grid layer 301, which is equivalent to a bearing member, so that the second vent pipe 200 is a pair of tubbiness with a hollow lower bottom, and holds a plurality of adsorption units 500. At this time, the bottom layer of the adsorption cavity is the diversion grid layer 301, the side cavity wall of the adsorption cavity is the inner wall of the second vent pipe 200, the top of the adsorption cavity is relatively open, and when the wind force is not strong enough or the adsorption unit 500 has relatively large mass, the air flow does not blow the adsorption unit out of the second vent pipe 200, so the equipment can work safely. In order to improve safety and facilitate additional components, in some embodiments, a blocking structure for blocking the adsorption unit 500 from being detached from the second outlet is disposed at the second outlet, and the blocking structure has a plurality of exhaust ports. More specifically, in some embodiments, the barrier structure is a mesh 400 covering the second outlet.

The number of the flow guide grid layers 301 is not limited to only one, and a plurality of flow guide grid layers 301 may be arranged along the second vent pipe 200, so that the adsorption cavity may be divided into a plurality of cavities in the vertical direction by arranging the plurality of flow guide grid layers 301, and the top sealing cover of the uppermost cavity is the blocking structure. A plurality of the adsorption units 500 are respectively filled into each layer of the cavity, and the number and specification of the filling may be determined according to the specification, and some cavities may be left empty.

In some embodiments, the flow guide grid layer 301 is a structure that: the central column 303 is coaxial with the second vent pipe 200, that is, when the second vent pipe 200 is vertically arranged, the central column 303 is also vertical, the guide plate 304 is overall long and straight and has a first connecting end and a second connecting end, the width of the first connecting end is slightly smaller than that of the second connecting end, the first connecting end is connected with the side peripheral wall of the central column 303, the guide plate 304 is obliquely arranged relative to the horizontal plane, the second connecting end is connected with the inner wall of the second vent pipe 200, the guide plates 304 are distributed around the central column 303 at equal intervals, and the guide port 302 is defined between two adjacent guide plates 304. Of course, in order to ensure that the adsorption unit 500 does not fall off, the width of the diversion opening 302 should be smaller than the outer diameter of the adsorption unit 500. More specifically, in order to enhance the structural strength and facilitate the installation, in some embodiments, an inner ring 305 and an outer ring 306 are further added to the flow guiding grid layer 301, the inner ring 305 and the outer ring 306 are concentric rings concentric with the central column 303, the outer ring 306 is connected to the second connection end of the flow guiding plate 304, the inner ring 305 is connected to the middle portion of the flow guiding plate 304, and 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 through the outer ring 306. The shape of the flow guide grid layer 301 is similar to that of a fan blade surface, and the formed annular uniformly-distributed inclined flow guide openings 302 guide air flow which enters and exits from the lower part and is blown out from the upper part of the flow guide openings 302 to form rotary dispersing mixed fluid, and the cyclone air flow is matched with water mist sprayed by the second water supply device, so that the adsorption unit 500 has a good adsorption and purification effect. Certainly, the present invention does not limit that the shape and structure of each guide grid layer 301 must be equal, and on the premise of ensuring the cleaning effect, the present invention allows adaptive changes to each guide grid layer 301 according to the actual situation, such as increasing or decreasing the guide plate 304, adjusting the inclination of the guide opening 302, or adding a grid in the cavity, and so on.

In some embodiments, the adsorption unit 500 comprises an equatorial ring 501, a first adsorption plate 502, a second adsorption plate 504, a first polar ring 503, a second polar ring 505, the equatorial ring 501 being located in the middle, dividing the adsorption unit 500 into a northern hemisphere and a southern hemisphere, with reference to the longitude and latitude positions of a conventional sphere, the first polar ring 503 being located at the upper top of the northern hemisphere, and the second polar ring 505 being located at the lower top of the southern hemisphere. The first adsorption plate 502 is positioned in a northern hemisphere, the whole appearance of the first adsorption plate is a right-angled triangle, the hypotenuse of the first adsorption plate is arc-shaped, and the right-angled edge at the upper end and the right-angled edge at the lower end are respectively connected with the first polar ring 503 and the equatorial ring 501; the second adsorption plate 504 is located in the southern hemisphere, the overall shape of the second adsorption plate is a right triangle, the hypotenuse of the second adsorption plate is arc-shaped, the radian of the hypotenuse of the second adsorption plate is matched with the arc edge of the first adsorption plate 502, and the right-angle edge at the upper end and the right-angle edge at the lower end of the second adsorption plate are respectively connected with the equatorial ring 501 and the second polar ring 505. The first adsorption plates 502 and the second adsorption plates 503 are uniformly distributed around the central axis of the equatorial ring 501 in a radial manner at equal intervals, and in the circumferential direction, any one second adsorption plate 504 is located between two adjacent first adsorption plates 502, that is, the first adsorption plate 502 and the second adsorption plate 503 are located on different meridian lines. More specifically, in some embodiments, the equatorial ring 501 has three passages from the outside to the inside, each positioned at the equatorial plane of the adsorption unit 500, and the three passages 501 are each connected to a first adsorption plate 502 and a second adsorption plate 503. The equatorial ring 501 is provided with a plurality of wind-dispersing small holes which are circumferentially spaced at equal intervals around the center of the equatorial ring 501. The multi-channel equatorial ring 501 improves the overall strength of the adsorption unit 500, and avoids the structural damage of the adsorption unit 500 caused by variable tangential stress generated by multiple collisions of rotation and rolling under the conditions of overlarge wind power and less and lighter materials.

The adsorption unit 500 of the structure is spherical in overall appearance, the vacancy reserved between the structures is used as a wind-dispelling flow channel, airflow can pass through the vacancy in a disordered mode, the first adsorption plate 502 and the second adsorption plate 503 have large wind shielding areas, the contact chance of the adsorption unit 500 and the gas is increased, and complicated channels are formed in the region filled with a large number of adsorption units 500 inevitably, and the adsorption units are favorable for adhesion and aggregation of liquid drops and finally flow and recovery under the traction area of spray water. The multi-layer equatorial ring 501 makes the adsorption unit 500 more firm in structure, and a plurality of ring structures in the upper, middle and lower parts are matched with the adsorption plates at intervals, so that the gas in the wind-dispelling flow channel flows more smoothly. The design of the wind-dispersing apertures allows the weight of the adsorption unit 500 to be reduced. Second adsorption plate 503 and the dislocation set of first adsorption plate 502 on the north-south hemisphere for even take place to heavily collide between two absorption units 500, also can not make because of the existence of long gap and inlay between board and block and tie-up, make rotatory rolling obstructed between the board. The reason is that, assuming that two adsorption units 500 which collide with each other are an a unit and a b unit respectively, taking the structures with mutual nesting tendency as the first adsorption plates 502 as an example, the convex arc edge of any one first adsorption plate 502 on the a unit can only be nested and cut into the gap between two adjacent first adsorption plates 502 on the b unit at most, and due to the blocking of the first polar ring 503 and the equatorial ring 501, the width of the plate gap can not allow the arc edge to be further cut, so that several technical requirements of ensuring that the wind shielding area is large enough, the wind dredging flow channel is smooth and can be prevented from being nested with each other are structurally met. The principle of blocking nesting of other structural parts of the adsorption unit 500 is similar to the above analysis. Of course, in order to facilitate the filling and replacement of the adsorption unit 500, the adsorption unit 500 may be made of light plastic.

In other embodiments, the first vent pipe 100 is disposed below the second vent pipe 200, the first inlet of the first vent pipe 100 faces downward, and the first outlet faces upward, so that the gas output from the first vent pipe 100 directly enters the second inlet and then enters the adsorption cavity through the diversion port, and since the flail plate 101 rotates at a high speed, the purification effect is not greatly affected even if the water-facing surface faces downward. At this time, the waste liquid flowing out from the first vent pipe 100 and the second vent pipe 200 can be collected at the same time only by disposing the funnel chamber 700 below the first vent pipe 100.
