Description

Technical Field

[0002] Waste gas treatment mainly refers to the work of treating industrial waste gas generated in industrial sites. The waste gas mainly includes dust particles, flue gas, odorous gases, toxic and harmful gases, etc. When treating the waste gas, it is necessary to first use a filtering and collecting device to filter and collect the particulate impurities in the waste gas, and then perform secondary treatment on the waste gas. If there is no polluting gas in the gas, it will be directly discharged after impurities are removed.

[0003] At present, most of the exhaust gas filtering and collecting devices adopt filter mesh filtration. The filter mesh is easy to be clogged after long-term use, which affects the gas flow rate and may affect the gas filtering efficiency and filtering effect. Some filters adopt vibration or backblowing to achieve self-cleaning. When filtering humid gas, impurities will adhere to the filter mesh and have a certain humidity, which makes it difficult to clean, thus affecting the filtering and collecting efficiency and filtering and collecting effect of the exhaust gas.

[0018] Beneficial effects:

[0020] 2. The filtering and collecting device for waste gas treatment filters the waste gas through multiple filter plates when the waste gas moves upward along the purification spiral sheet, so that some impurities in the waste gas adhere to the filter plate, and the impurities attached to the filter plate move toward the sponge layer again under the action of centrifugal force, and the gradually accumulated impurities are not easily carried away by the gas, thereby effectively improving the filtering effect of the waste gas.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Example 1: Reference Figure 1-Figure 12A filter collection device for waste gas treatment, comprising: a housing 1, and also comprising: an outer cylinder 109, which is arranged in the housing 1; an inner cylinder 2, which is sealed and rotatably connected in the outer cylinder 109, and a filter chamber 204 and a storage chamber 206 are arranged in the inner cylinder 2, and a first through hole 205 is arranged between the filter chamber 204 and the storage chamber 206; a first motor 110, which is fixedly arranged at the lower end of the outer cylinder 109, and the output end of the first motor 110 is fixedly connected to the inner cylinder 2; an air intake pipe 1 01, arranged on one side of the housing 1, an intake ring 111 connected to the intake pipe 101 is arranged on the outer cylinder 109, and an intake port 202 connected to the intake ring 111 is arranged on the inner cylinder 2; the exhaust pipe 102 is arranged at the upper end of the housing 1; the fixed shaft 4 is arranged in the inner cylinder 2; the second motor 201 is fixedly connected in the inner cylinder 2, and the output end of the second motor 201 is fixedly connected to the fixed shaft 4; the sponge layer 207 is fixedly arranged in the inner cylinder 2; the purification spiral The sheet 5 is fixedly arranged on the fixed shaft 4, and the outer side of the purification spiral sheet 5 is in contact with the sponge layer 207; the collecting ring 113 is fixedly arranged in the outer cylinder 109, and one side of the collecting ring 113 matches the upper edge of the sponge layer 207; a plurality of filter plates 501 are fixedly arranged on the lower edge of the purification spiral sheet 5 in a spiral shape; the processing area 505 is arranged between two adjacent filter plates 501; the steam chamber 403 is arranged in the fixed shaft 4; a plurality of steam nozzles 404 are fixedly connected to the fixed shaft 4 in a spiral shape, and the steam nozzles 404 are connected to the steam chamber 403, the steam nozzles 404 are arranged in the processing area 505, and a solenoid valve is arranged in the steam nozzles 404; a steam supply assembly is arranged in the box body 1, and the steam supply assembly is used to supply steam to the steam chamber 403; the controller 103 is fixedly arranged in the box body 1; the collecting bottle 108 is detachably connected to one side of the outer cylinder body 109, and the collecting bottle 108 is connected to the collecting ring 113.

[0038] The steam supply assembly includes a filtered water tank 104 fixedly arranged in the housing 1, a steam generator 105 is arranged on the upper side of the filtered water tank 104, a first connecting pipe 602 is arranged at the supply end of the steam generator 105, the first connecting pipe 602 is connected to the steam chamber 403, and the liquid inlet end of the steam generator 105 is connected to the filtered water tank 104, wherein, when the first connecting pipe 602 is specifically connected to the steam chamber 403, a first annular cavity 6 connected to the steam chamber 403 is arranged in the fixed shaft 4, and a first sealing ring 601 is sealingly rotatably connected to the upper end of the fixed shaft 4, the first sealing ring 601 is connected to the first annular cavity 6, and the first sealing ring 601 is connected to the first connecting pipe 602.

[0039] In a specific implementation, the solenoid valves in the steam spray heads 404 in two adjacent processing areas 505 are numbered so that the steam spray heads 404 are divided into two groups. The two groups of steam spray heads 404 are staggered and controlled by the controller 103 to work intermittently and alternately.

[0040] When filtering the moist exhaust gas, the supply end of the exhaust gas is connected to the intake pipe 101, and the exhaust gas enters the storage chamber 206 through the intake pipe 101, the intake ring 111 and the intake port 202 in turn, and then enters the filter chamber 204 through the first through hole 205. The exhaust gas entering the filter chamber 204 moves upward along the purification spiral sheet 5, and the exhaust gas contacts the moist sponge layer 207 and adsorbs on the sponge layer 207. The controller 103 controls the first motor 110 to drive the inner cylinder 2 to rotate. The rotation of the inner cylinder 2 causes the moist impurities in contact with the purification spiral sheet 5 to move toward the sponge layer 207 and finally adsorb on the sponge layer 207. The controller 103 regulates the steam generator 105 and the two sets of solenoid valves to make the steam nozzle 404 spray intermittently. The intermittently sprayed steam quickly drives the impurities in the exhaust gas to move toward the sponge layer 207. At the same time, the small water droplets in the steam can quickly adsorb the impurities in the exhaust gas, thereby effectively improving the filtering effect of the exhaust gas.

[0041] When the exhaust gas moves upward along the purification spiral sheet 5, the exhaust gas is filtered by multiple filter plates 501, so that some impurities in the exhaust gas adhere to the filter plates 501, and the impurities attached to the filter plates 501 move toward the sponge layer 207 again under the action of centrifugal force. The gradually accumulated impurities are not easily carried away by the gas, thereby effectively improving the filtering effect of the exhaust gas.

[0042] The intermittently ejected steam back-blows the filter plate 501, so that the impurities blocked in the filter plate 501 move toward the lower surface of the purification spiral sheet 5 along with the steam. When the impurities come into contact with the purification spiral sheet 5, they are thrown onto the sponge layer 207 under the action of centrifugal force, thereby effectively improving the collection effect of impurities in the exhaust gas.

[0043] The alternately intermittently ejected steam facilitates the impurities on the filter plate 501 to move to the lower surface of the purification spiral sheet 5 better, and prevents the gas turbulence caused by the simultaneous ejection of steam in the adjacent processing area 505 from affecting the cleaning effect of the filter plate 501.

[0044] The controller 103 controls the second motor 201 to drive the fixed shaft 4 to rotate, and the fixed shaft 4 drives the purification spiral blade 5 to rotate. The rotating purification spiral blade 5 continuously scrapes off the impurities attached to the surface of the sponge layer 207, pushing it upward, and finally falls into the collecting ring 113 under the action of centrifugal force. The impurities in the collecting ring 113 are relatively moist. The impurities in the collecting ring 113 enter the collecting bottle 108, thereby effectively collecting the impurities.

[0045] The continuously ejected steam can provide water resources for the sponge layer 207 .

[0046] Example 2: Reference Figure 1-Figure 12 , a filtering and collecting device for exhaust gas treatment, which is basically the same as Example 1, and further, a water removal cylinder 3 is sealed and rotatably connected in the outer cylinder 109, an exhaust hole 302 is provided at the upper end of the water removal cylinder 3, a plurality of connecting rods 301 are fixedly connected between the water removal cylinder 3 and the inner cylinder 2, a water removal spiral sheet 307 matching the water removal cylinder 3 is fixedly connected to the fixed shaft 4, a plurality of sponge nets 308 are fixedly connected to the water removal spiral sheet 307, a reflux ring 112 is provided on the outer cylinder 109, a reflux port 203 matching the reflux ring 112 is provided on the inner cylinder 2, and the reflux ring 112 is connected to the water inlet end of the filtered water tank 104.

[0047] A reflux chamber 401 is arranged in the fixed shaft 4, a third through hole 402 is symmetrically arranged at the lower end of the fixed shaft 4, a water storage ring 303 is arranged at the lower side of the water removal cylinder 3, a transit ring 304 is sealingly rotatably connected to the fixed shaft 4, a second through hole 306 for connecting the transit ring 304 and the reflux chamber 401 is arranged on the fixed shaft 4, and a plurality of reflux pipes 305 are fixedly connected between the transit ring 304 and the water storage ring 303.

[0048] The filtered water tank 104 may be, but is not limited to, a water storage tank with a filtering function.

[0049] The gas purified by the purification spiral sheet 5 and the filter plate 501 in the filter chamber 204 enters the water removal cylinder 3 upward, and the gas is filtered through a plurality of sponge nets 308. The sponge nets 308 with certain small holes can effectively reduce the resistance to the gas, so that the gas in the inner cylinder body 2 has a certain flow tendency, and the sponge nets 308 absorb the residual moisture in the gas, and throw the water out under the action of centrifugal force. The thrown water gradually flows downward into the water storage ring 303 under the action of gravity. The water collected by the water storage ring 303 passes through the reflux pipe 305, the transfer ring 304, the second through hole 306, the reflux chamber 401, the third through hole 402, the reflux port 203 and the reflux ring 112 in turn and enters the filter water tank 104 for recycling, thereby effectively discharging the moisture from the gas and preventing small water droplets from taking away impurities in the exhaust gas.

[0050] Example 3: Reference Figure 1-Figure 12 , a filtering and collecting device for waste gas treatment, which is basically the same as Example 1, and further, the purification spiral sheet 5 squeezes the sponge layer 207 to form a spiral protrusion 208.

[0051] The protrusion 208 facilitates the cleaning spiral blade 5 to scrape away impurities on the sponge layer 207 .

[0052] A water spray chamber 405 is arranged in the fixed shaft 4, and the water spray chamber 405 is arranged on the upper side of the steam chamber 403. A plurality of water spray heads 406 connected to the water spray chamber 405 are fixedly connected to the fixed shaft 4, and the water spray heads 406 are arranged in the processing area 505. A water pump 106 is arranged on the upper side of the filtered water tank 104, and the water pumping end of the water pump 106 is connected to the filtered water tank 104. A second connecting pipe 702 is fixedly connected to the drainage end of the water pump 106, and the second connecting pipe 702 is connected to the water spray chamber 405. When the second connecting pipe 702 is specifically connected to the water spray chamber 405, a second annular chamber 7 connected to the water spray chamber 405 is arranged in the fixed shaft 4, and a second sealing ring 701 connected to the second annular chamber 7 is sealingly rotatably connected on the fixed shaft 4, and the second sealing ring 701 is connected to the second connecting pipe 702.

[0053] The controller 103 controls the water pump 106 to supply water to the water spray chamber 405, and sprays water mist in the form of large water droplets through multiple water spray heads 406. The water mist can quickly cool the residual steam, so that the water droplets in the residual steam contact each other to form large water droplets, thereby effectively reducing the water content in the gas and adsorbing the residual impurities in the gas, thereby effectively improving the filtering effect of impurities in the exhaust gas.

[0054] Example 4: Reference Figure 1-Figure 12 , a filtering and collecting device for waste gas treatment, which is basically the same as Example 1, and further, a water inlet pipe 506 and a water outlet pipe 507 are arranged in the purification spiral sheet 5, a circulating cooler 107 is arranged in the box body 1, and a third connecting pipe 802 and a fourth connecting pipe 902 are arranged on the circulating cooler 107, the third connecting pipe 802 is connected to the water inlet pipe 506, and the fourth connecting pipe 902 is connected to the water outlet pipe 507, wherein, in a specific embodiment, a third annular cavity 8 and a fourth annular cavity 9 are arranged on the fixed shaft 4, and a third sealing ring 801 and a fourth sealing ring 901 are rotatably connected to the outer side of the fixed shaft 4, the third sealing ring 801 is connected to the third annular cavity 8, the third sealing ring 801 is connected to the third connecting pipe 802, and the fourth sealing ring 901 is connected to the fourth connecting pipe 902.

[0055] The water in the water inlet pipe 506 and the water outlet pipe 507 is continuously circulated and cooled by the circulating cooler 107 to cool the purification spiral blade 5. When the cooled purification spiral blade 5 treats the high-temperature and humid exhaust gas, the exhaust gas can cool down after contacting with the purification spiral blade 5, and part of the moisture in the high-temperature and humid exhaust gas will cool down to form water droplets on the surface of the purification spiral blade 5, thereby facilitating the adsorption of impurities in the exhaust gas on the purification spiral blade 5, and finally flow to the sponge layer 207 under the action of centrifugal force and be adsorbed by the sponge layer 207.

[0056] When the steam sprayed from the steam nozzle 404 passes through the filter plate 501, the steam drives the impurities to move to the lower surface of the purification spiral blade 5. At this time, the steam is cooled to form large water droplets that gather on the purification spiral blade 5, thereby effectively preventing the impurities from being attached to the filter plate 501 again along with the exhaust gas, thereby effectively improving the filtering effect and filtering efficiency of impurities in the exhaust gas.

[0057] Example 5: Reference Figure 1-Figure 12 , a filtering and collecting device for waste gas treatment, which is basically the same as Example 1, and further, the filter plate 501 is set at an angle, and the end of the steam nozzle 404 is inclined toward the filter plate 501.

[0058] A connecting portion 502 is provided on the filter plate 501 , and a flow guide portion 503 is provided between the connecting portion 502 and the purification spiral sheet 5 .

[0059] The contact surface of the filter plate 501 with the exhaust gas is provided with a plurality of equidistantly arranged transverse grooves 504 .

[0060] Some impurities and small water droplets on the lower surface of the purification spiral sheet 5 will flow to the guide portion 503 under the action of the rotation of the purification spiral sheet 5, and the impurities in the guide portion 503 will flow to the sponge layer 207 along the connecting portion 502 under the action of centrifugal force, so that they are adsorbed on the sponge layer 207, thereby facilitating the impurities to quickly contact with the sponge layer 207, improving the collection efficiency of the impurities, and preventing too many impurities from accumulating on the purification spiral sheet 5 and affecting its collection effect.

[0061] Among them, the connecting part 502 fits tightly with the protrusion 208, so that more water droplets and impurities can be gathered between the connecting part 502 and the protrusion 208. Water enters the sponge layer 207 under the action of centrifugal force, and the gathered impurities are more convenient for the purification spiral sheet 5 to be transported upward. The gathered impurities are also convenient for sticking to other impurities that are inconvenient to be pushed and moving upward. When it moves to the top of the purification spiral sheet 5, it is easier to enter the collecting ring 113, thereby effectively improving the collection effect of impurities in the exhaust gas.
