Description

Technical Field

[0001] The utility model belongs to the technical field of industrial waste gas treatment, and particularly relates to a filtering and adsorbing device for industrial waste gas treatment. Background Art

[0002] At present, industrial waste gas with complex components is generated during industrial production, and it needs to be treated to meet the standards before being discharged. Moreover, a large amount of dust particles are contained in some industrial waste gas. If directly introduced into the adsorption device, the micropores of the adsorption material will be blocked, resulting in a reduction in its specific surface area, a decrease in adsorption capacity or even loss. The existing filtering and adsorbing devices have the following problems during use: 1) Some devices use a filter screen at the front end of the adsorption device for dust filtration to achieve the purification purpose, but their automation degree is not high. It is necessary for the staff to regularly stop the machine, take out the filter screen for cleaning and maintenance, and then put it back to continue working, which greatly affects the efficiency of waste gas treatment; 2) Most of the existing adsorption devices install one or more groups of adsorption materials in the adsorption box to achieve the adsorption purpose. However, after the industrial waste gas undergoes aggregation pretreatment, its concentration will change. That is, when the concentration is high, multiple-stage adsorption is required to achieve the purification purpose, and when the concentration is low, not too much adsorption material is needed to participate. The non-adjustable adsorption plate is difficult to adapt to the fluctuating concentration changes, resulting in incomplete waste gas purification or waste of adsorption materials.

[0003] After retrieval, the prior art CN220194416U discloses an industrial waste gas purification device. When the waste gas enters the machine body, it will first be filtered for powder substances by the filter screen in the air inlet pipe. The filtered dust impurities will fall through the ash discharge hole into the ash box for unified collection. The waste gas after filtration will enter the combustion chamber, and the gas in the gas tank will be ejected from the gas gun to fully burn the waste gas, thereby removing the combustible waste gas. By pulling up the partition sealing plate, the waste gas will enter the purification chamber from the gap at the bottom of the partition sealing plate. At the same time, the motor is started to drive the hollow net plate on the rotating rod and the support rod to adsorb the toxic waste gas substances in the purification chamber. Similarly, by pulling up the partition sealing plate, the gas will enter the disinfection chamber through the gap, and the gas will be irradiated by multiple ultraviolet lamps in the disinfection chamber for the final disinfection and sterilization steps; the above technical solution still has the following problems during use: 1) The ash box is directly connected to the air inlet pipe. When the waste gas blows, the dust inside the ash box will be blown up due to the influence of pressure and flow rate, affecting the collection effect, and there is no additional cleaning mechanism for the single filter screen, and it is difficult for the dust to quickly fall on the filter screen; 2) Although the rotating activated carbon adsorption structure can accelerate the air circulation, it cannot ensure direct contact and circulation with the waste gas, resulting in low purification efficiency, and it cannot adjust the contact area between the activated carbon and the waste gas, and has poor adaptability.

[0004] The prior art CN218166341U discloses a high-efficiency activated carbon adsorption device for industrial waste gas, including a waste gas treatment box and a waste gas filter element; an air inlet pipe and an air outlet pipe are respectively arranged on the left and right sides of the waste gas treatment box, a waste gas filter element is arranged inside the waste gas treatment box, a filter cartridge in the shape of a filter screen is arranged inside the waste gas filter element, multiple adsorption cartridges are arranged outside the filter cartridge, activated carbon packing is filled inside each group of adsorption cartridges, the adsorption cartridge located on the outermost side of the waste gas filter element is communicated with the air outlet pipe, a rotating brush plate and rotating blades are also installed in the inner cavity of the waste gas filter element, and the rotating brush plate and the rotating blades are fixed on a rotating shaft driven by a motor, so that the mesh holes of the filter cartridge can be conveniently cleaned; the following problems still exist in the use of the above technical solution: Although setting two groups of adsorption cartridges to complete the treatment of waste gas purification can improve the purification rate, when treating low-concentration waste gas, the purification operation can be completed without passing through too much adsorption material, resulting in the idleness of the remaining adsorption cartridges. The redundant adsorption cartridges will still age when contacting air, and it will affect the flow of waste gas, unable to improve the waste gas treatment efficiency, and at the same time will cause an increase in the installation cost. Summary of the Invention

[0005] The purpose of the present utility model is to overcome the deficiencies in the prior art and provide a filtering and adsorbing device for industrial waste gas treatment. By setting multiple-stage filter meshes, dust pretreatment is carried out first, and two adjustable activated carbon adsorption structures are arranged in the adsorption cartridge, which can be adjusted in position according to the waste gas concentration at any time to improve the purification efficiency.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

The top of the treatment cylinder is fixedly communicated with the air inlet pipe. Inside the treatment cylinder, there are a fixing plate I and a fixing plate II, which are fixedly installed on the inner top wall of the treatment cylinder. A first filter mesh and a second filter mesh are respectively installed below the fixing plate I and the fixing plate II. The centers of the first filter mesh and the second filter mesh are movably installed on the movable cylinder. The top end of the movable cylinder passes through the through hole above the treatment cylinder and is fixedly connected to the output end of the motor. The other end of the movable cylinder is movably installed on the partition plate inside the treatment cylinder. A dust collection chamber is arranged below the partition plate. A dust collection box is movably installed in the groove at the bottom of the dust collection chamber. An adsorption cartridge is arranged in the cavity between the partition plate and the second filter mesh. One end of the adsorption cartridge is fixedly communicated with the air outlet pipe;

[0008] On the side wall of the movable cylinder, there are two layers of several dust collection holes Ⅰ distributed vertically. The bottom of the dust collection holes Ⅰ is attached to the side walls of the first filter screen and the second filter screen. Above the two layers of dust collection holes Ⅰ, a brush Ⅰ and a brush Ⅱ are respectively fixedly installed. The brush Ⅰ is attached to the surface of the first filter screen, and the brush Ⅱ is attached to the second filter screen. Inside the movable cylinder, there is an adjusting cylinder. One end of the adjusting cylinder is open, and the other end is fixedly connected to one end of an electric telescopic rod. The other end of the electric telescopic rod is fixedly installed on the movable cylinder. The adjusting cylinder is provided with dust collection holes Ⅱ corresponding to the positions of the dust collection holes Ⅰ.

[0009] At the bottom of the end of the movable cylinder extending into the dust collection chamber, a scraper is installed through a fixing frame.

[0010] The first filter screen and the second filter screen are conical in shape. The filter holes of the first filter screen are 1.5 times those of the second filter screen, achieving the purpose of multi-stage filtration. And the conical shape is convenient for the dust to slide down and can increase the contact area with the industrial waste gas, improving the filtration efficiency.

[0011] On one side of the fixing plate Ⅰ and the fixing plate Ⅱ, a guide groove Ⅰ and a guide groove Ⅱ are respectively provided, which can provide guidance for the brush Ⅰ and the brush Ⅱ, reduce friction and guide the brush Ⅰ and the brush Ⅱ to perform circular motion, ensuring the cleaning effect.

[0012] The adsorption cylinder is provided with several air permeable holes Ⅰ. Inside the adsorption cylinder, a rotating cylinder is movably installed. The rotating cylinder is provided with several air permeable holes Ⅱ corresponding to the positions of the air permeable holes Ⅰ. On the inner side wall of the rotating cylinder, several limiting strips Ⅰ are fixedly installed. Inside the rotating cylinder, an adsorption cylinder Ⅰ is movably installed. The adsorption cylinder Ⅰ is meshed and installed on the limiting strips Ⅰ. The adsorption cylinder Ⅰ is provided with several activated carbon plates Ⅰ corresponding to the positions of the air permeable holes Ⅱ. Inside the adsorption cylinder Ⅰ, an adsorption cylinder Ⅱ is movably installed. The limiting groove on the adsorption cylinder Ⅱ is meshed and movably installed with the limiting strips Ⅱ on the inner side wall of the adsorption cylinder Ⅰ. The adsorption cylinder Ⅱ is provided with several activated carbon plates Ⅱ corresponding to the positions of the activated carbon plates Ⅰ;

[0013] One side of the adsorption cylinder Ⅱ is fixedly installed with a threaded sleeve through a mounting frame and movably installed on a screw rod. The screw rod is movably installed at one end of the adsorption cylinder Ⅰ and passes through the movable cover. The movable cover is movably installed at one end of the adsorption cylinder. One end of the screw rod passing through the movable cover is movably installed with a lever;

[0014] After the industrial waste gas passes through the dust filter, it enters the interior of the adsorption cylinder through the air permeation hole Ⅰ. It is determined whether it is necessary to fully expand the adsorption cylinder Ⅰ and the adsorption cylinder Ⅱ according to the concentration of the industrial waste gas. When the concentration is low, turn the lever to drive the screw to rotate, so that the adsorption cylinder Ⅱ moves along the limit groove and extends out of the adsorption cylinder Ⅰ. At this time, the adsorption cylinder Ⅰ and the adsorption cylinder Ⅱ can work simultaneously to improve the adsorption efficiency of the waste gas. After the waste gas passes through the air permeation hole Ⅰ on the adsorption cylinder and the air permeation hole Ⅱ on the rotating cylinder and is adsorbed by the activated carbon plate Ⅰ and the activated carbon plate Ⅱ, it flows to one end of the adsorption cylinder and is discharged through the air outlet pipe. When the waste gas concentration is high, turn the lever to drive the screw to rotate, so that the adsorption cylinder Ⅱ contracts into the interior of the adsorption cylinder Ⅰ. At this time, the waste gas needs to pass through two layers of activated carbon before entering the interior of the adsorption cylinder, which can ensure the adsorption efficiency of the waste gas. When the adsorption work has been carried out for a period of time and the activated carbon needs to be treated, turn the lever to make the screw drive the adsorption cylinder Ⅱ to contract into the interior of the adsorption cylinder Ⅰ. After reaching the shortest limit, continue to turn the lever. At this time, the screw will drive the adsorption cylinder Ⅱ, the adsorption cylinder Ⅰ and the rotating cylinder to rotate synchronously. After rotating a certain angle, the air permeation hole Ⅱ on the rotating cylinder is misaligned and closed with the air permeation hole Ⅰ on the adsorption cylinder. At this time, the waste gas will not continue to enter the interior of the adsorption cylinder. After removing the movable cover, the adsorption cylinder Ⅰ and the adsorption cylinder Ⅱ can be taken out as a whole for treatment. After the treatment is completed, the adsorption cylinder Ⅰ and the adsorption cylinder Ⅱ are put into the interior along several limit strips Ⅰ on the rotating cylinder, and the movable cover is covered. Then, it can be adjusted according to the waste gas concentration, which greatly improves the adsorption efficiency of the activated carbon and can adapt to the change of the waste gas concentration through adjustment, ensuring the stability of adsorption.

[0015] The beneficial effects of the present utility model compared with the prior art are as follows:

[0016] 1) After the industrial waste gas enters the treatment cylinder through the air inlet pipe, it is first filtered for dust through two layers of filter nets to prevent dust from blocking the activated carbon pores and affecting the waste gas adsorption. During the dust filtering work, the electric telescopic rod extends to drive the adjusting cylinder to move, so that the dust collection hole Ⅰ and the dust collection hole Ⅱ are misaligned and closed to prevent gas from entering. After the dust filtering for a period of time, the air intake is paused, and the motor drives the movable cylinder to rotate. At this time, the electric telescopic rod contracts to drive the adjusting cylinder to move, so that the dust collection hole Ⅰ and the dust collection hole Ⅱ are aligned. At the same time, since the motor drives the movable cylinder to rotate, the brush Ⅰ and the brush Ⅱ will follow the movable cylinder to clean the surfaces of the first filter net and the second filter net, brush off the dust particles on their surfaces, and the dust will slide through the dust collection hole Ⅰ and the dust collection hole Ⅱ into the interior and enter the dust collection chamber through the movable cylinder for unified collection and treatment, avoiding the disturbance of the waste gas to the dust;

[0017] 2) During the process of the motor driving the movable cylinder to rotate, it can drive the scraper to scrape the dust scattered on the side wall of the dust collection chamber. During the rotation process, the dust can be scraped into the dust collection box for unified collection, which is convenient for the staff to handle;

[0018] 3) It can be adjusted in real time according to the concentration of waste gas in the adsorption cylinder. When the concentration is low, turn the lever to drive the screw to rotate, so that the adsorption cylinder II moves out of the adsorption cylinder I along the limit groove. At this time, the adsorption cylinder I and the adsorption cylinder II can work simultaneously, improving the adsorption efficiency of waste gas. When the concentration of waste gas is high, turn the lever to make the screw rotate, so that the adsorption cylinder II shrinks into the adsorption cylinder I. At this time, the waste gas needs to pass through two layers of activated carbon before entering the adsorption cylinder, improving the purification level. Through the adjustment of the two groups of adsorption cylinders, it can adapt to the purification operation of waste gas with different concentrations, improving the efficiency of waste gas treatment and ensuring the full utilization of the activated carbon adsorption plate.

One end of the adsorption cylinder 21 is fixedly communicated with the outlet pipe 22;

[0030] On the side wall of the movable cylinder 17, there are two layers of a number of dust collecting holes Ⅰ 171 distributed vertically. The bottom of the dust collecting holes Ⅰ 171 is attached to the side walls of the first filter net 14 and the second filter net 15. Above the two layers of dust collecting holes Ⅰ 171, a brush Ⅰ 175 and a brush Ⅱ 176 are respectively fixedly installed. The brush Ⅰ 175 is attached to the surface of the first filter net 14, and the brush Ⅱ 176 is attached to the second filter net 15. Inside the movable cylinder 17, there is an adjusting cylinder 173. One end of the adjusting cylinder 173 is open, and the other end is fixedly connected to one end of the electric telescopic rod 172. The other end of the electric telescopic rod 172 is fixedly installed on the movable cylinder 17. On the adjusting cylinder 173, there are dust collecting holes Ⅱ 174 corresponding to the positions of the dust collecting holes Ⅰ 171; after industrial waste gas enters the treatment cylinder 10 through the intake pipe 11, it first passes through the two layers of filter nets for dust filtration to prevent dust from blocking the activated carbon pores and affecting waste gas adsorption. During the dust filtration work, the electric telescopic rod 172 extends to drive the adjusting cylinder 173 to move, so that the dust collecting holes Ⅰ 171 and the dust collecting holes Ⅱ 174 are misaligned and closed to prevent gas from entering. After dust filtration for a period of time, the intake is paused, and the motor 16 drives the movable cylinder 17 to rotate. At this time, the electric telescopic rod 172 contracts to drive the adjusting cylinder 173 to move, so that the dust collecting holes Ⅰ 171 and the dust collecting holes Ⅱ 174 are aligned. At the same time, because the motor 16 drives the movable cylinder 17 to rotate, the brush Ⅰ 175 and the brush Ⅱ 176 will follow the movable cylinder 17 to clean the surfaces of the first filter net 14 and the second filter net 15, brush off the dust particles on their surfaces, and the dust will slide down through the dust collecting holes Ⅰ 171 and the dust collecting holes Ⅱ 174 into the interior, and enter the dust collecting chamber 19 through the movable cylinder 17.

[0031] At the bottom of the end of the movable cylinder 17 extending into the dust collecting chamber 19, a scraper 178 is installed through a fixing frame 177.

During the rotation process, the dust is scraped into the dust collecting box 20 for unified collection, which is convenient for the staff to handle.

[0032] The shapes of the first filter net 14 and the second filter net 15 are conical. The filter holes of the first filter net 14 are 1.5 times larger than those of the second filter net 15, which is convenient for the dust to slide down, and can increase the contact area with industrial waste gas and improve the filtration efficiency.

[0034] A plurality of air-permeable holes Ⅰ211 are formed in the adsorption cylinder 21. A rotating cylinder 212 is movably installed inside the adsorption cylinder 21. A plurality of air-permeable holes Ⅱ2122 corresponding to the positions of the air-permeable holes Ⅰ211 are provided on the rotating cylinder 212.

[0036] After being filtered for dust, the industrial waste gas enters the interior of the adsorption cylinder 21 through the ventilation holes I 211. It is decided whether to fully expand the adsorption cylinder I 213 and the adsorption cylinder II 214 according to the concentration of the industrial waste gas. When the concentration is low, turn the lever 216 to drive the screw 215 to rotate, so that the adsorption cylinder II 214 moves along the limiting groove 2142 and extends out of the adsorption cylinder I 213. At this time, the adsorption cylinder I 213 and the adsorption cylinder II 214 can work simultaneously to improve the adsorption efficiency of the waste gas.

When the concentration of the waste gas is high, turn the lever 216 to drive the screw 215 to rotate, so that the adsorption cylinder II 214 contracts into the interior of the adsorption cylinder I 213. At this time, the waste gas needs to pass through two layers of activated carbon before entering the interior of the adsorption cylinder 21, which can ensure the adsorption efficiency of the waste gas. When the activated carbon needs to be processed after a period of adsorption work, turn the lever 216 to make the screw 215 drive the adsorption cylinder II 214 to contract into the interior of the adsorption cylinder I 213. After reaching the shortest limit, continue to turn the lever 216. At this time, the screw will drive the adsorption cylinder II 214, the adsorption cylinder I 213 and the rotating cylinder 212 to rotate synchronously. After rotating a certain angle, the ventilation holes II 2122 on the rotating cylinder 212 are misaligned and closed with the ventilation holes I 211 on the adsorption cylinder 21.

After the processing is completed, the adsorption cylinder I 213 and the adsorption cylinder II 214 are put in as a whole along the several limiting strips I 2121 on the rotating cylinder 212, and the movable cover is covered. Then, it can be adjusted according to the concentration of the waste gas, greatly improving the adsorption efficiency of the activated carbon and ensuring the adsorption stability by adjusting to adapt to the change of the waste gas concentration.

After dust filtering for a period of time, the intake is paused, and the motor 16 drives the movable cylinder 17 to rotate. At this time, the electric telescopic rod 172 contracts to drive the adjustment cylinder 173 to move, so that the dust collection hole I 171 and the dust collection hole II 174 are aligned. At the same time, since the motor 16 drives the movable cylinder 17 to rotate, the brush I 175 and the brush II 176 will follow the movable cylinder 17 to clean the surfaces of the first filter mesh 14 and the second filter mesh 15, brush off the dust particles on their surfaces, and let them slide through the dust collection hole I 171 and the dust collection hole II 174 into the interior, and enter the dust collection chamber 19 through the movable cylinder 17. The dust that enters the dust collection chamber 19 will drive the scraper 178 to scrape the dust scattered on the side wall of the dust collection chamber 19 during the process of the motor 16 driving the movable cylinder 17 to rotate.
