Description

Technical Field

[0001] The invention belongs to the technical field of graphite production, in particular to a desulfurization and denitrification device for isostatic graphite production. Background Art

[0002] The desulfurization and denitrification device used in the production of isostatic graphite is a special environmental protection equipment. In the production process of isostatic graphite, waste gas containing a large amount of pollutants will be generated, among which sulfur dioxide and nitrogen oxides are the main harmful components. The desulfurization and denitrification device can mainly remove sulfur dioxide and nitrogen oxides contained in the production tail gas through various methods such as chemical or physical methods, thereby reducing the emission of these harmful gases to meet the relevant requirements of environmental protection.

[0003] In a desulfurization and denitrification device, the desulfurization process requires that the exhaust gas be transported to a desulfurization tank, and a desulfurizer such as limestone slurry is connected from an external device through a nozzle, which is sprayed in the desulfurization tank and brought into contact with the exhaust gas, thereby generating a reaction to convert sulfur dioxide into gypsum, thereby achieving sulfur removal. In some prior arts, the nozzle position in the desulfurization tank is fixed, and concentrated spraying can only be performed within a certain range. After entering the desulfurization tank, the gas will quickly diffuse into the entire tank body. The nozzle spraying range is too small and may not be able to fully react with the exhaust gas, thereby reducing the desulfurization efficiency. Therefore, in view of the above problems, a desulfurization and denitrification device for isostatic graphite production is proposed. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a desulfurization and denitrification device for isostatic graphite production, which solves the problem that the desulfurizer in the prior art cannot fully contact with the exhaust gas, thereby reducing the desulfurization efficiency.

[0005] To achieve the above object, the present invention provides the following technical solution: a desulfurization and denitration device for isostatic graphite production, comprising a desulfurization tank and a denitration tank, the outer wall of the desulfurization tank is fixedly connected with an air intake pipe, the outer wall of the desulfurization tank is provided with a dust removal mechanism through a conveying pipe, and the inner wall of the desulfurization tank is provided with a composite mechanism;

[0006] The composite mechanism includes a motor, the output shaft of the motor is fixedly connected to a rotating shaft, the bottom outer wall of the rotating shaft is fixedly connected to a fixed block, the bottom outer wall of the fixed block is fixedly connected to a sliding block, the inner wall of the desulfurization tank is fixedly connected to a guide rod, the outer wall of the guide rod is slidably connected to a moving block, the outer wall of the moving block is provided with a sliding groove, the inner wall of the desulfurization tank is fixedly connected to a rack, the bottom outer wall of the moving block is fixedly connected to a medicine box, the bottom outer wall of the medicine box is rotatably connected to a nozzle, the outer wall of the medicine box is fixedly connected to a drug delivery tube, and the outer wall of the nozzle is fixedly connected to a gear.

[0009] Preferably, the moving block is slidably connected to the outer wall of the guide rod, the gear is meshed with the rack, and the drug delivery tube passes through the outer wall of the desulfurization tank.

[0010] Preferably, one end of the connecting spring is fixedly connected to the outer wall of the protrusion, and the other end of the connecting spring is fixedly connected to the inner wall of the rotating block.

[0011] Preferably, the rotating shaft passes through the outer wall of the rotating block, and the protrusion is slidably connected to the inner wall of the rotating block.

[0012] Preferably, the dust removal mechanism includes a dust removal box, the inner wall of the dust removal box is fixedly connected to a filter screen, the outer wall of the dust removal box is rotatably connected to a turntable, the outer wall of the turntable is hinged to a movable plate via a connecting rod, the outer wall of the movable plate is hinged to a sliding rod via a hinge rod, and the outer wall of the sliding rod is fixedly connected to a soft brush.

[0013] Preferably, the dust removal box is fixedly connected to the outer wall of the denitrification tank, the dust removal box is fixedly connected to the delivery pipe, and the soft brush is in contact with the outer wall of the filter.

[0014] Preferably, one end of the connecting rod is hinged to the outer wall of the movable plate, and the other end of the connecting rod is hinged to the outer wall of the rotating disk.

When the motor drives the rotating shaft to rotate, the rotating block will rotate synchronously. The convex block inside the rotating block will continuously contact the inner wall of the sieve hole on the sieve, so as to clear the inner wall of the sieve hole, thereby avoiding the problem that the sieve hole is blocked by desulfurizer droplets or solid impurities in the gas after the exhaust gas passes through the sieve, thereby affecting the screening and conveying efficiency.

[0019] The present invention cooperates with structures such as a soft-bristle brush and a filter screen. Before the desulfurized exhaust gas is transported to the denitrification tank through a delivery pipe, smaller impurities will be filtered through the filter screen. When the filter screen is clogged due to long-term use, the turntable can be rotated to drive the sliding rod and the soft-bristle brush to move up and down through the connecting rod, the moving plate, and the hinged rod, so that the surface of the filter screen can be cleaned, thereby avoiding the problem of filter screen clogging affecting the exhaust gas transportation effect.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 5 As shown, the present invention provides a desulfurization and denitration device for isostatic graphite production, comprising a desulfurization tank 1 and a denitration tank 6, wherein the outer wall of the desulfurization tank 1 is fixedly connected to an air inlet pipe 3, the outer wall of the desulfurization tank 1 is provided with a dust removal mechanism 5 through a delivery pipe 4, and the inner wall of the desulfurization tank 1 is provided with a composite mechanism 2; the composite mechanism 2 comprises a motor 201, the output shaft of the motor 201 is fixedly connected to a rotating shaft 202, the bottom outer wall of the rotating shaft 202 is fixedly connected to a fixed block 209, and the bottom outer wall of the fixed block 209 is fixedly connected to There is a slider 210, the inner wall of the desulfurization tank 1 is fixedly connected with a guide rod 211, the outer wall of the guide rod 211 is slidably connected with a moving block 207, the outer wall of the moving block 207 is provided with a slide groove 208, the inner wall of the desulfurization tank 1 is fixedly connected with a rack 213, the bottom outer wall of the moving block 207 is fixedly connected with a medicine box 212, the bottom outer wall of the medicine box 212 is rotatably connected with a nozzle 215, the outer wall of the medicine box 212 is fixedly connected with a drug delivery tube 216, and the outer wall of the nozzle 215 is fixedly connected with a gear 214.

[0030] The above scheme is adopted: the desulfurization tank 1 and the denitration tank 6 are the main equipment bodies for desulfurization and denitration of the waste gas generated during the production of isostatic graphite, which is the existing technology, so as to achieve the purpose of purifying waste gas and reducing air pollution; the waste gas generated by the production of isostatic graphite can be first transported to the desulfurization tank 1 through the air inlet pipe 3, and after the desulfurization operation is completed inside the desulfurization tank 1, it enters the denitration tank 6 through the delivery pipe 4 to complete the denitration operation and be discharged; the motor 201 is used as the power source of the composite mechanism 2, and when it is started, the output shaft can drive the rotating shaft 202 to rotate, and the rotating shaft 202 penetrates the top outer wall of the desulfurization tank 1 and enters the tank. During the rotation process, it can drive the fixed block 209 on the outer wall of the bottom end to rotate, and the slider 210 moves along the circumference with the rotating shaft 202 as the center, and can squeeze the slide groove 208 to generate thrust for the moving block 207; because the moving block 207 is slidably connected with the guide rod 211 on the inner wall of the desulfurization tank 1, under the action of the slider 210, the moving block 207 can move back and forth linearly along the guide rod 211 horizontally.

[0031] like Figure 2 , Figure 3 and Figure 5As shown, the motor 201 is fixedly connected to the top outer wall of the desulfurization tank 1, the rotating shaft 202 passes through the top outer wall of the desulfurization tank 1, the slider 210 contacts the inner wall of the slide groove 208; the moving block 207 is slidably connected to the outer wall of the guide rod 211, the gear 214 is meshed with the rack 213, and the drug delivery tube 216 passes through the outer wall of the desulfurization tank 1.

[0032] The above scheme is adopted: the medicine box 212 on the outer wall of the bottom end of the moving block 207 can move synchronously with the moving block 207, and the medicine delivery pipe 216 on the outer wall of the medicine box 212 is used to transport the desulfurizer into the medicine box 212. The medicine delivery pipe 216 is a hose and will not be affected by pulling when the medicine box 212 moves; the nozzle 215 on the outer wall of the bottom end of the medicine box 212 is used to spray the desulfurizer in the medicine box 212, and the gear 214 on the outer wall of the nozzle 215 is meshed with the rack 213 on the inner wall of the desulfurization tank 1. When the moving block 207 moves horizontally, the gear 214 rolls along the rack 213. Since the rack 213 is not fixed, the gear 214 contacts the gear blocks of the two gears when rolling, which will drive the gear 214 and the nozzle 215 to rotate synchronously, so that the nozzle 215 can rotate during the reciprocating movement, thereby realizing a large-scale spraying of the desulfurizer, making the desulfurizer more evenly distributed in the desulfurization tank 1, and improving the desulfurization effect.

[0033] like Figure 3 and Figure 4 As shown, the outer wall of the rotating shaft 202 is fixedly connected to the rotating block 203, the inner wall of the rotating block 203 is elastically connected to the protrusion 205 through the connecting spring 204, and the inner wall of the desulfurization tank 1 is fixedly connected to the screen 206; one end of the connecting spring 204 is fixedly connected to the outer wall of the protrusion 205, and the other end of the connecting spring 204 is fixedly connected to the inner wall of the rotating block 203; the rotating shaft 202 passes through the outer wall of the rotating block 203, and the protrusion 205 is slidably connected to the inner wall of the rotating block 203.

[0034] The above scheme is adopted: after the exhaust gas reacts with the desulfurizer and completes the desulfurization, a complex gas-liquid-solid three-phase mixed system will be formed, and the exhaust gas will be transported upward from the delivery pipe 4 to the denitrification tank 6 under the action of the air pump of the delivery pipe 4. When being transported upward, it first passes through the screen 206. The screen 206 can be used to remove the desulfurizer droplets and possible solid particles entrained in the exhaust gas during the desulfurization process, and filter out larger impurities to avoid affecting the subsequent desulfurization operation; the protrusion 205 is hemispherical, with the arc surface facing downward, and the protrusion 205 has the same diameter as the sieve hole on the screen 206. When not affected by external force, the protrusion 205 pops up downward under the elastic force of the connecting spring 204 and contacts the inner wall of the sieve hole. When the motor 201 starts to drive the rotating shaft 202 to rotate, the rotating block 203 on the outer wall of the rotating shaft 202 rotates together with the rotating shaft 202. During the rotation, the arc surface of the protrusion 205 is squeezed by the inner wall of the sieve hole, moves upward to the inner wall of the rotating block 203, and squeezes the connecting spring 204. When the protrusion 205 rotates to correspond to the position of other sieve holes, it pops down again under the elastic force of the connecting spring 204 and contacts the inner wall of the sieve hole, so that the sieve hole can be dredged to prevent the desulfurizer or solid impurities from accumulating on the sieve 206 and clogging the sieve hole, ensuring that the flue gas can be smoothly screened through the sieve 206 and transported to the denitrification tank 6. There is no need to manually clean the sieve 206, which is more convenient.

[0035] like Figure 6 and Figure 7 As shown, the dust removal mechanism 5 includes a dust removal box 501, the inner wall of the dust removal box 501 is fixedly connected to a filter screen 502, the outer wall of the dust removal box 501 is rotatably connected to a turntable 503, the outer wall of the turntable 503 is hinged to a moving plate 505 through a connecting rod 504, the outer wall of the moving plate 505 is hinged to a sliding rod 507 through a hinge rod 506, and the outer wall of the sliding rod 507 is fixedly connected to a soft brush 508; the dust removal box 501 is fixedly connected to the denitration tank 6 The outer wall, the dust removal box 501 is fixedly connected to the conveying pipe 4, and the soft brush 508 contacts the outer wall of the filter screen 502; one end of the connecting rod 504 is hinged to the outer wall of the movable plate 505, and the other end of the connecting rod 504 is hinged to the outer wall of the turntable 503; one end of the articulated rod 506 is hinged to the outer wall of the sliding rod 507, and the other end of the articulated rod 506 is hinged to the outer wall of the movable plate 505, and the sliding rod 507 is slidably connected to the outer wall of the dust removal box 501.

[0036] The above scheme is adopted: the flue gas first enters the dust removal mechanism 5 through the conveying pipe 4, and the filter screen 502 arranged in the dust removal box 501 is used to filter the smaller dust particles in the flue gas to prevent the dust particles from covering the catalyst surface in the denitration tank 6, blocking the active sites of the catalyst, reducing the activity of the catalyst, and affecting the denitration efficiency; the turntable 503 on the outer wall of the dust removal box 501 is provided with a handle, and the operator can rotate the turntable 503 through the handle. When it rotates, it will pull the connecting rod 504 and the end hinged to it to move along the circumference, and drive the movable plate 505 to move through the connecting rod 504, and the movable plate 505 is slidably connected to the outer wall of the dust removal box 501, and it can only move horizontally on the outer wall of the dust removal box 501; there are two groups of hinged rods 506, which are symmetrically distributed on the upper and lower sides of the outer wall of the dust removal box 501. When 505 moves, it will drive the hinged rod 506 to move with its hinged end, and the other end of the hinged rod 506 will drive the sliding rod 507 to slide vertically along the outer wall of the dust removal box 501, and the soft brush 508 on the sliding rod 507 will contact the outer wall of the filter 502, so as to clean the filter 502, which can prevent the filter 502 from being blocked by dust, ensure the continuity of the dust removal effect, and enable the flue gas after dust removal to better enter the denitrification tank 6 for denitrification treatment; a mutually related connecting rod mechanism is formed between the turntable 503, the connecting rod 504, the moving plate 505, the hinged rod 506, the sliding rod 507 and the soft brush 508. When no external force is applied to the handle, each component will be in a balanced state under the action of internal forces such as gravity and friction, so that when the soft brush 508 is on the upper and lower sides, such as Figure 6 In the state shown, the filter screen 502 will not be blocked to affect its filtering effect.

[0037] The working principle and use process of the present invention:

[0038] The waste gas generated during the production of isostatic graphite can enter the desulfurization tank 1 through the air inlet pipe 3. At this time, the motor 201 is started, and the output shaft of the motor 201 drives the rotating shaft 202 to rotate. The fixed block 209 on the outer wall of the bottom end of the rotating shaft 202 rotates, and the slider 210 moves along the circumference with the rotating shaft 202 as the center and squeezes the slide groove 208, pushing the moving block 207 slidably connected to the guide rod 211 to move horizontally and reciprocatingly along the guide rod 211. The medicine box 212 on the outer wall of the bottom end of the moving block 207 moves synchronously. The medicine delivery pipe 216 transports the desulfurizer from the external device into the medicine box 212, and the nozzle 215 on the outer wall of the bottom end of the medicine box 212 sprays the desulfurizer. At the same time, the gear 214 on the outer wall of the nozzle 215 is meshed with the rack 213 on the inner wall of the desulfurization tank 1. When the moving block 207 moves horizontally, the gear 214 rolls along the rack 213 to drive the nozzle 215 to rotate synchronously, thereby realizing a large-scale and uniform spraying of the desulfurizer in the desulfurization tank 1, and the exhaust gas and the desulfurizer fully react to perform the desulfurization operation, thereby improving the efficiency of the desulfurization operation.

[0039] The waste gas after desulfurization forms a three-phase mixed system of gas, liquid and solid, which is transported upward under the action of the air pump of the conveying pipe 4, and first passes through the screen 206, which can remove the desulfurizer droplets and possible solid particles entrained in the waste gas; when the motor 201 drives the rotating shaft 202 to rotate, the rotating block 203 on the outer wall of the rotating shaft 202 rotates, and the protrusion 205 is squeezed by the inner wall of the sieve hole, and will continuously move toward the inner wall of the rotating block 203, and then contact the inner wall of the sieve hole under the elastic force of the connecting spring 204, so as to realize continuous dredging of the sieve hole to prevent blockage, and ensure that the flue gas can smoothly pass through the screen 206 into the conveying pipe 4, so as to prevent impurities in the flue gas from affecting the subsequent denitrification operation.

[0040] The flue gas enters the dust removal box 501 in the dust removal mechanism 5 through the conveying pipe 4, and the filter 502 in the dust removal box 501 can further filter the tiny dust particles in the flue gas; after long-term use, a large amount of impurities will adhere to the surface of the filter 502, which will affect the filtering and flue gas conveying effects. At this time, the operator can rotate the turntable 503 with a handle on the outer wall of the dust removal box 501, and the turntable 503 pulls the connecting rod 504 to make one end move along the circumference, driving the movable plate 505 to move horizontally on the outer wall of the dust removal box 501, and the movable plate 505 drives the sliding rod 507 to slide vertically along the outer wall of the dust removal box 501 through the hinged rod 506. The two sets of sliding rods 507 drive the corresponding soft brushes 508 to clean the filter 502, so that the impurities on the surface of the filter 502 are detached, which can prevent the filter 502 from being blocked by dust and ensure the dust removal effect; the flue gas after dust removal enters the denitrification tank 6 for denitrification operation, and finally the treated gas is discharged.
