Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and specifically provides a waste gas treatment device. Background Art

[0002] The adsorbent can adsorb a variety of substances in the gas through its dense pore structure, thus achieving the purpose of purifying the gas. When using the adsorbent to purify the waste gas, due to the limited adsorption capacity of the adsorbent, after a period of purification and adsorption, the adsorbent will reach a saturated state, resulting in a poor purification effect or even cessation of adsorption. At this time, the adsorbent needs to be replaced or desorbed.

[0003] Exhaust gas treatment devices in the prior art often use steam desorption when desorbing adsorbents. Steam heats the adsorbent to reduce its adsorption of the adsorbate, thereby desorbing the adsorbate. The adsorbate and the liquid after steam condensation form waste liquid and are discharged from the pipeline together. When there are many adsorbates or the use time is long, the adsorbate is easy to block the pipeline, and the pipeline is located inside the treatment device, which is not convenient for cleaning, resulting in increased maintenance costs.

[0004] Accordingly, the art needs a new exhaust gas treatment device to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the above technical problem, that is, to solve the problem that the waste gas treatment device in the prior art is prone to clogging the pipeline when steam desorbing the adsorbent.

[0006] The utility model provides an exhaust gas treatment device, characterized in that the exhaust gas treatment device comprises: a box body, a purification chamber is formed in the box body; a purification component, the purification component comprises an adsorption structure, the adsorption structure is arranged in the purification chamber, and an adsorbent is arranged on the adsorption structure; a desorption component, the desorption component comprises a conveying structure, a liquid collecting structure and a guide groove, the conveying structure is used to convey steam to the purification chamber, the liquid collecting structure is arranged on the bottom side of the adsorption structure, the liquid collecting structure is provided with a liquid outlet, the first end of the guide groove is arranged on the bottom side of the liquid outlet, and the second end of the guide groove is arranged lower than the first end.

[0007] In the case of adopting the above-mentioned technical scheme, through the setting of the liquid collecting structure and the guide groove, when the adsorbent needs to be desorbed, the steam is transported to the purification chamber through the conveying structure, and the steam desorbs the adsorbent. The obtained waste liquid falls on the liquid collecting structure on the bottom side of the adsorption structure under the action of gravity, and flows from the liquid outlet to the first end of the guide groove on the bottom side of the liquid outlet, and then flows from the first end to the lower second end, thereby solving the problem of easy blockage of the pipeline.

[0008] In a specific embodiment of the above-mentioned exhaust gas treatment device, the liquid collecting structure is a liquid collecting hopper, and the liquid outlet is provided on the bottom wall of the liquid collecting hopper.

[0009] When the above technical solution is adopted, the setting of the liquid collecting hopper can facilitate the collection of waste liquid. The waste liquid is quickly collected together along the side wall of the liquid collecting hopper under the action of gravity and finally flows out from the liquid outlet on the bottom wall.

[0010] In a specific embodiment of the above-mentioned exhaust gas treatment device, the second end is arranged outside the box body, and the desorption component also includes a collecting box, which is arranged outside the box body and communicated with the second end.

[0011] When the above technical solution is adopted, concentrating the waste liquid in the collection box can facilitate further processing and recycling of the waste liquid. The waste liquid is directly guided to the collection box outside the box by the guide groove. No other pipeline structure is required in the box, which further avoids the problem of pipeline blockage.

[0012] In a specific embodiment of the above-mentioned exhaust gas treatment device, a drain pipe is provided at the bottom of the collecting box.

[0013] When the above technical solution is adopted, the provision of the drain pipe can facilitate the cleaning of the collection box and the further processing and recycling of the waste liquid.

[0014] In a specific embodiment of the above-mentioned exhaust gas treatment device, the delivery structure is a delivery pipe, and the outlet end of the delivery pipe is arranged on the bottom side of the liquid collecting structure.

[0015] When the above technical solution is adopted, since the steam temperature is relatively high and the density is relatively low, it will move upward after entering the purification chamber, and since the outlet end is arranged at the bottom side of the liquid collecting structure, and the liquid collecting structure is arranged at the bottom side of the adsorption structure, the outlet end is also arranged at the bottom side of the liquid collecting structure. The steam flows out from the outlet end, and contacts with the adsorbent on the adsorption structure during the upward movement, and desorbs the adsorbate, and the waste liquid descends and falls directly on the liquid collecting structure, thereby preventing the waste liquid from falling on the delivery pipe, causing corrosion to the delivery pipe or clogging the outlet end.

[0016] In a specific embodiment of the above-mentioned exhaust gas treatment device, the desorption component also includes a steam generating device, and the inlet end of the delivery pipe is connected to the steam generating device.

[0017] When the above technical solution is adopted, the steam generating device generates steam and delivers the steam to the purification chamber through the delivery pipe.

[0018] In a specific embodiment of the above-mentioned exhaust gas treatment device, a partition plate is provided in the box body, and the partition plate divides the internal space of the box body into the purification chamber at the top and the air intake chamber at the bottom, and a through hole is provided on the partition plate; the exhaust gas treatment device also includes a centrifugal fan, which is arranged in the air intake chamber, and the air outlet of the centrifugal fan is connected to the through hole.

[0019] When the above technical solution is adopted, the partition plate divides the internal space of the box into a purification chamber and an air intake chamber. The centrifugal fan sucks the exhaust gas into the air intake chamber and guides the exhaust gas through the through hole into the purification chamber to adsorb and purify the exhaust gas.

[0020] In a specific embodiment of the above-mentioned exhaust gas treatment device, the centrifugal fan is a double-suction centrifugal fan, and the exhaust gas treatment device also includes a diverter plate, which is vertically arranged in the air intake cavity, and the two air inlets of the double-suction centrifugal fan are respectively arranged on both sides of the diverter plate.

[0021] When the above technical solution is adopted, the diverter plate will divert the exhaust gas entering the air intake chamber so that the exhaust gas enters the centrifugal fan from the two air inlets of the double-suction centrifugal fan, thereby reducing wind resistance, improving air intake efficiency, and thereby improving the efficiency of exhaust gas adsorption and purification.

[0022] In a specific embodiment of the above-mentioned exhaust gas treatment device, the air intake chamber is provided with an air intake port, and a filter is provided at the air intake port; and / or the exhaust gas treatment device also includes a collecting box, which is arranged on the bottom side of the air intake chamber, and the box body is provided with an installation groove, and the collecting box can be detachably installed in the installation groove.

[0023] When the above technical solution is adopted, by setting the filter at the air intake port, the exhaust gas can be filtered when entering the air intake chamber from the air intake port, and larger impurities can be filtered out to avoid damage to the centrifugal fan; by setting the collecting box, when the exhaust gas in the air intake chamber enters the centrifugal fan from the air inlet, the impurities that cannot enter the centrifugal fan fall into the collecting box, and when the collecting box needs to be cleaned, it can be taken out from the mounting slot for cleaning.

[0024] In a specific embodiment of the above-mentioned exhaust gas treatment device, the purification component also includes an exhaust pipe and an induced blower. The exhaust pipe is arranged at the top of the box and is connected to the purification chamber. The induced blower is arranged on the top side of the adsorption structure in the purification chamber.

[0025] When the above technical solution is adopted, the induced fan is used to provide upward attraction to the gas in the box, assisting the centrifugal fan to guide the gas flow, so that the exhaust gas can keep moving toward the top. After the exhaust gas is adsorbed and purified by the adsorbent, it continues to move to the top side and is discharged out of the box through the exhaust pipe.

[0026] Compared with the prior art, the beneficial effect of the waste gas treatment device provided by the utility model is: through the setting of the liquid collecting structure and the guide groove, when the adsorbent needs to be desorbed, the steam is transported to the purification chamber through the conveying structure, and the steam desorbs the adsorbent. The obtained waste liquid falls on the liquid collecting structure on the bottom side of the adsorption structure under the action of gravity, and flows from the liquid outlet to the first end of the guide groove on the bottom side of the liquid outlet, and then flows from the first end to the lower second end, which solves the problem of easy blockage of the pipeline.

The obtained waste liquid falls onto the liquid collecting structure on the bottom side of the adsorption structure under the action of gravity, and flows from the liquid outlet to the first end of the guide groove on the bottom side of the liquid outlet, and then flows from the first end to the lower second end, thereby solving the problem of easy clogging of the pipeline.

Figure 2 This is a schematic diagram of the internal structure of the waste gas treatment device of the utility model. Figure 3 It is a partial structural schematic diagram of the waste gas treatment device of the utility model. Figure 4 FIG. 2 is another schematic diagram of the structure of the waste gas treatment device of the utility model. Figure 1-Figure 4As shown, the waste gas treatment device of the utility model includes a housing 1, a centrifugal fan 2, a purification component 3 and a desorption component 4. A partition plate 11 is provided in the housing 1, and the partition plate 11 divides the internal space of the housing 1 into a purification chamber 12 at the top and an air suction chamber 13 at the bottom, and a through hole 111 is provided on the partition plate 11. The centrifugal fan 2 is a double-suction centrifugal fan, which is arranged in the air suction chamber 13, and the air outlet of the double-suction centrifugal fan is connected to the through hole 111. The double-suction centrifugal fan is used to suck the waste gas into the air suction chamber 13, and guide the waste gas through the through hole 111 to the purification chamber 12 to adsorb and purify the waste gas. Since the double-suction centrifugal fan is provided with two air inlets, the air suction volume of the fan can be increased. The purification component 3 includes an adsorption structure 31, an exhaust pipe 32 and an induced fan 33. The adsorption structure 31 is arranged in the purification chamber 12. An adsorbent is arranged on the adsorption structure 31, and the adsorbent can adsorb and purify the exhaust gas; the exhaust pipe 32 is arranged at the top of the box body 1 and is connected to the purification chamber 12, and is used to discharge the purified gas out of the box body 1; the induced fan 33 is arranged on the top side of the adsorption structure 31 in the purification chamber 12. The induced fan 33 is used to provide an upward attraction for the gas in the box body 1, and assist the centrifugal fan 2 to guide the gas flow, so that the exhaust gas can keep moving toward the top. After the exhaust gas is adsorbed and purified by the adsorbent, it continues to move to the top side and is discharged from the exhaust pipe 32 outside the box body 1. The desorption component 4 includes a steam generating device 41, a delivery pipe 42, a liquid collecting hopper 43, a guide groove 44 and a collecting box 45. The inlet end of the delivery pipe 42 is connected to the steam generating device 41, and the outlet end of the delivery pipe 42 is arranged at the bottom side of the liquid collecting structure. The delivery pipe 42 is used to deliver the steam generated by the steam generating device 41 to the purification chamber 12; the liquid collecting hopper 43 is arranged at the bottom side of the adsorption structure 31, and a liquid outlet 431 is arranged on the liquid collecting hopper 43. The arrangement of the liquid collecting hopper 43 can facilitate the collection of waste liquid. The waste liquid is quickly collected together along the side wall of the liquid collecting hopper 43 under the action of gravity, and finally flows out from the liquid outlet 431 on the bottom wall; the first end 441 of the guide groove 44 is arranged at the bottom side of the liquid outlet 431, and the second end 442 of the guide groove 44 is lower than the first end 441 of the guide groove 44. One end 441 is provided and arranged outside the box body 1, and the waste liquid flows along the first end 441 of the guide groove 44 to the second end 442. The setting of the guide groove 44 avoids the problem that the adsorbent easily blocks the pipeline when there are a lot of adsorbents or the use time is long; the collecting box 45 is provided outside the box body 1 and is connected to the second end 442. The waste liquid is concentrated in the collecting box 45, which can facilitate the further treatment and recovery of the waste liquid. The waste liquid is directly guided to the collecting box 45 outside the box body 1 by the guide groove 44. There is no need to set other pipeline structures in the box body 1, which further avoids the problem of pipeline blockage. A drain pipe 451 is provided at the bottom of the collecting box 45. The setting of the drain pipe 451 can facilitate the cleaning of the collecting box 45 and the further treatment and recovery of the waste liquid.

[0039] The exhaust gas treatment device also includes a diverter plate 5, which is vertically arranged in the air suction chamber 13. The two air inlets of the double-suction centrifugal fan are respectively arranged on both sides of the diverter plate 5. The diverter plate 5 diverts the exhaust gas entering the air suction chamber 13 so that the exhaust gas enters the centrifugal fan 2 from the two air inlets of the double-suction centrifugal fan, thereby reducing wind resistance, improving air suction efficiency, and thereby improving the efficiency of exhaust gas adsorption and purification.

[0040] The air inlet 14 is provided in the air inlet 13, and the air inlet 14 is provided on the side wall of the box body 1 at the air inlet 13. A filter screen 6 is provided at the air inlet 14. The setting of the filter screen 6 allows the exhaust gas to be filtered when it enters the air inlet 13 from the air inlet 14, and the larger impurities are filtered out to avoid damage to the centrifugal fan 2. The exhaust gas treatment device also includes a collection box 7, which is provided on the bottom side of the air inlet 13. The box body 1 is provided with a mounting groove 15, and the collection box 45 can be detachably installed in the mounting groove 15. Through the setting of the collection box 7, when the exhaust gas in the air inlet 13 enters the centrifugal fan 2 from the air inlet, the impurities that cannot enter the centrifugal fan 2 fall into the collection box 7. When the collection box 7 needs to be cleaned, it can be taken out from the mounting groove 15 for cleaning.

[0041] When treating waste gas, the double suction centrifugal fan and the induced fan 33 are started. The double suction centrifugal fan is started to generate negative pressure in the suction chamber 13, and the waste gas is attracted to enter the suction chamber 13 from the suction port 14. The waste gas in the suction chamber 13 is diverted by the diverter plate 5, and enters the two air inlets of the double suction centrifugal fan from both sides of the diverter plate 5, and then is discharged from the air outlet, and enters the purification chamber 12 through the through hole 111. The waste gas continues to move toward the top side under the combined action of the thrust of the double suction centrifugal fan and the suction of the induced fan 33, and at the same time passes through the adsorption structure 31, and the waste gas is adsorbed and purified by the adsorbent. The purified gas continues to move toward the top side and is finally discharged from the exhaust pipe 32 to the outside of the box 1. After the adsorbent is saturated with adsorption, the purification effect deteriorates or even stops adsorption. At this time, the adsorbent needs to be replaced or desorbed.

[0042] When the adsorbent needs to be desorbed, the double-suction centrifugal fan and the induced fan 33 are turned off, the exhaust gas purification is stopped, and the steam generating device 41 is started. The steam generating device 41 generates steam and conveys it to the purification chamber 12 through the conveying pipe 42. The steam desorbs the adsorbent, and the resulting waste liquid falls into the liquid collecting bucket 43 on the bottom side of the adsorption structure 31 under the action of gravity, and flows from the liquid outlet 431 on the bottom wall of the liquid collecting bucket 43 to the first end 441 of the guide groove 44 on the bottom side of the liquid outlet 431, and then flows from the first end 441 to the lower second end 442, which solves the problem of easy blockage of the pipeline, and the waste liquid enters the collection box 45 outside the box body 1 from the second end 442.

[0043] Possibly, the adsorption structure 31 is a box-shaped structure, the adsorption structure 31 is filled with an adsorbent, and the top and bottom of the adsorption structure 31 are air-permeable. The adsorbent may be activated carbon, zeolite, activated alumina, resin, etc., as long as it is an adsorbent that can adsorb and purify gas and desorb steam.

[0044] It should be noted that the steam generating device 41 can be a coal-fired steam generator, or a coal-fired steam generator or an oil-fired steam generator, etc., as long as it can generate steam; the steam can be water vapor, or the steam of other desorbents such as calcium chloride.

[0045] Those skilled in the art may understand that, although it is described above that the exhaust gas treatment device includes an intake chamber 13, this is not restrictive. The exhaust gas treatment device may not include the intake chamber 13, and the exhaust gas directly enters the purification chamber 12, and the exhaust gas is adsorbed and treated by the adsorbent on the adsorption structure 31.

[0046] In addition, the liquid collecting hopper 43 can also be a liquid collecting box or other liquid collecting structures, as long as it can collect the waste liquid desorbed from the adsorption structure 31 during steam desorption and discharge the waste liquid from the liquid outlet 431. The delivery pipe 42 can also be other delivery structures such as delivery holes on the box body 1, as long as it can deliver steam to the purification chamber 12. The centrifugal fan 2 can be a double-suction centrifugal fan, or a single-suction centrifugal fan or other types of fans, as long as it can achieve the purpose of sucking the waste gas into the suction chamber 13 and guiding it to the purification chamber 12. The above adjustments do not deviate from the principle of the utility model and are within the protection scope of the utility model.

[0047] Those skilled in the art will appreciate that, although it is described above that the second end 442 of the guide groove 44 is disposed outside the casing 1, this is not restrictive, and the second end 442 may also be disposed inside the casing 1, and then guided from the inside of the casing 1 to other structures for processing or recycling the waste liquid.

[0048] Regarding the number of exhaust pipes 32, it can be set to one or more, and can be optionally three, to achieve a better exhaust effect. Accordingly, the number of induced fans 33 can be the same as the number of exhaust pipes 32, or it can be different. In addition, the induced fan 33 can be arranged on the top side of the adsorption structure 31 in the purification chamber 12, or it can be arranged in the exhaust pipe 32, as long as it can provide an upward attraction for the gas in the box body 1. When a plurality of induced fans 33 are provided and arranged on the top side of the adsorption structure 31 in the purification chamber 12, the induced fans 33 can be installed together on a mounting frame, and the mounting frame is connected to the box body 1 at the purification chamber 12.

[0049] Possibly, the exhaust gas treatment device further includes a support plate 8 , wherein two support plates 8 are provided, respectively disposed at two opposite sides of the air suction cavity 13 , so as to improve the strength of the air suction cavity 13 and prevent the side wall of the box body 1 from being deformed.

[0050] It should be noted that the above-mentioned implementation modes are only used to illustrate the principles of the present invention and are not intended to limit the protection scope of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above-mentioned implementation modes so that the present invention can be applied to more specific application scenarios.

[0051] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
