Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for dye production. BACKGROUND

[0002] 1,4-naphthoquinone is a dye raw material, also known as alpha-naphthoquinone, yellow crystal, with the special smell of benzoquinone, sublimation when the temperature exceeds 100℃, slightly soluble in water and gasoline, easily soluble in ethanol when heated, soluble in diethyl ether, chloroform, benzene, glacial acetic acid and carbon disulfide. It is commonly used for dye, medicine and bactericide. The main method for producing 1,4-naphthoquinone in China at present is naphthalene gas phase oxidation method. The naphthalene gas phase oxidation method for preparing 1,4-naphthoquinone uses air as the oxidant and naphthalene is directly oxidized to prepare 1,4-naphthoquinone under the action of vanadium catalyst such as vanadium pentoxide.

[0003] The gas phase oxidation method used in the production of 1,4-naphthoquinone produces waste gas. The vanadium catalyst is weathered into particles due to the airflow and high temperature, and enters the waste gas. Since the vanadium catalyst is carcinogenic, it pollutes the air greatly, and a bag-type dust collector needs to be used for dust removal. The bag needs to be cleaned regularly during use.

[0004] In the prior art, the cleaning is carried out by mechanical knocking or pulse back blowing. The mechanical knocking is noisy and has poor dust removal effect, and is gradually eliminated. The pulse back blowing cleaning method has become the mainstream. After long-term use of the bag, the dust on the surface of the bag absorbs water in the air, and blocks the filter holes of the bag. The gas flow of the pulse back blowing dust removal is small, and the cleaning effect is poor, so that the dust block adhered to the surface of the bag cannot be removed. At the same time, since the pulse back blowing cleaning method is to blow a large amount of airflow into the bag at a moment, the airflow has a very large pressure at the moment, and the bag is impacted by a downward impact force, the impact force is more than 200N, a large tensile force is generated at the connection between the bag and the bag opening fixing ring, and after a plurality of cleanings, the position where the bag contacts the partition plate is pulled and broken, or even directly broken, so that the dust collector is disabled. SUMMARY

[0005] The present application aims to provide a waste gas treatment device for dye production, and aims to solve the problem that the dust block adhered to the bag is difficult to remove in the prior art.

[0006] The above technical purpose of the present application is achieved by the following technical scheme:

[0007] The utility model provides a kind of waste gas treatment device for dye production, including box, the partition is horizontally arranged inside the box, a plurality of ventilation round holes are formed in the partition, the ventilation round hole is provided with the air injection pipe directly above, bag is provided with cloth bag passing through the ventilation round hole, support cage is provided in the cloth bag, the periphery of the ventilation round hole is uniformly provided with a plurality of fixed blocks, the top of the fixed block gradually increases along the periphery of the ventilation round hole, and the top of the fixed block has a set height, the bag mouth of the cloth bag is provided with a fixed ring, the bottom of the fixed ring is uniformly provided with a plurality of sliding blocks, the sliding block corresponds with the fixed block one by one, the fixed block is hinged with leakage-proof plate, the hinged place of the fixed block and the leakage-proof plate is provided with torsion spring, the side surface of the leakage-proof plate cooperates with the side surface of the sliding block, the top of the support cage is hinged with a plurality of connecting plates, the connecting plate is fixedly connected with the top of the partition, and the support cage is provided with docking mechanism for connecting the cloth bag.

[0008] Through the above technical scheme, when installing the cloth bag, the bottom of the cloth bag is put down through the ventilation round hole until the sliding block is located at the high place on the fixed block, the leakage-proof plate covers the sliding block from the side, then the support cage is put into the cloth bag from the opening of the cloth bag, the cloth bag is stretched out, the support cage is cylindrical, the cloth bag is also cylindrical after being stretched out, the support cage moves downward to the set height, is connected with the inner bottom of the cloth bag through the docking mechanism, then the connecting plate is connected with the top of the partition, the position of the support cage is fixed, a part of the weight of the support cage is borne by the connecting plate and the partition, so the bearing capacity of the cloth bag is reduced. After a period of waste gas treatment, dust accumulates on the outer surface of the cloth bag, some dust coagulates into blocks due to absorbing part of the moisture in the air, and the surface of the cloth bag needs to be cleaned. The air injection pipe sprays high-speed airflow into the cloth bag, the high-speed airflow diffuses downward along the cloth bag, and the gas is blown from the inside of the cloth bag to the outside of the cloth bag, so that the dust on the surface of the cloth bag is blown off. Due to the instantaneous downward impact force of the high-speed airflow on the cloth bag, the sliding block slides from the high place to the low place on the fixed block, and the leakage-proof plate is pushed outward by the sliding block. At this time, the bag opening rotates by a certain angle. Since the bottom of the cloth bag is connected with the support cage, it will not rotate with the cloth bag, so the entire cloth bag is twisted, the dust blocks and shells coagulated on the outer surface of the cloth bag are loosened, and the large dust blocks directly fall or break into small blocks, which are then directly cleaned by the high-speed gas. After the high-speed gas pulse back-blowing cleaning is completed, due to the stress of the cloth bag material, the shape of the cloth bag restores, and under the action of the torsion spring, the leakage-proof plate pushes the sliding block back to the high place of the fixed block, completing the reset of the bag opening of the cloth bag. At the same time, due to the impact force of the gas on the cloth bag, part of the bag opening can move downward by a small distance, reducing the tensile force on the bag opening and the wear of the bag opening, and increasing the service life of the cloth bag.

[0009] The further arrangement of the present application is that the docking mechanism comprises a docking cylinder arranged at the lower end of the supporting cage, a docking cavity is arranged in the docking cylinder, the cross section of the docking cavity is circular, the bottom of the inside of the cloth bag is provided with a docking piece matched with the docking cavity, a plurality of sliding grooves are vertically arranged on the side wall of the docking cylinder and penetrate the bottom of the docking cylinder, and a plurality of docking rods matched with the sliding grooves are horizontally arranged on the docking piece.

[0010] Through the above technical scheme, when the supporting cage moves downward, the docking piece is inserted into the docking cylinder, then the docking rod is inserted into the sliding groove, the outer diameter of the docking rod is equal to the width of the sliding groove, when the upper part of the cloth bag rotates, the bottom of the cloth bag will not rotate due to the fact that the docking rod is clamped in the sliding groove, and the cloth bag produces a twisting effect.

[0011] The further arrangement of the present application is that the top of the sliding groove is horizontally provided with a clamping groove, and the clamping groove and the sliding groove are communicated with the docking cavity.

[0012] Through the above technical scheme, when the cloth bag needs to be replaced, the supporting cage is continuously moved downward by a certain distance, the docking rod is in contact with the top of the sliding groove, then the supporting cage is rotated, the docking rod is inserted into the clamping groove, and then the supporting cage is lifted up, since the docking rod is located in the clamping groove and cannot move up and down, the bottom of the cloth bag will be lifted up together with the supporting cage, when the supporting cage is completely taken out, the inner bottom of the cloth bag is also moved above the partition plate, the cloth bag is completed to be turned over, and after the cloth bag is disassembled, only the bag opening needs to be tied, and then the cloth bag can be recycled, since the outer surface of the cloth bag becomes the inner surface after the cloth bag is taken out, dust adsorbed on the cloth bag will not be diffused into the air in a large amount, and pollution to the working environment is reduced.

[0013] The further arrangement of the present application is that the end of the clamping groove away from the sliding groove is vertically provided with an anti-rotation groove, and the top of the anti-rotation groove is communicated with the end of the clamping groove.

[0014] Through the above technical scheme, when the cloth bag is taken out, the supporting cage is rotated, the docking rod is inserted into the clamping groove, the supporting cage is continuously rotated, the docking rod is inserted into the connection between the clamping groove and the anti-rotation groove, the supporting cage is lifted up, and the docking rod is inserted into the anti-rotation groove, so that the docking rod is prevented from rotating in the clamping groove and returning to the sliding groove.

[0015] The further arrangement of the present application is that the connecting plate is provided with a locking hole, the top of the partition plate is provided with a locking screw rod, the locking screw rod penetrates the locking hole, the locking screw rod is provided with a locking nut, the inner diameter of the locking hole is equal to the outer diameter of the locking screw rod, and the number of the sliding grooves and the number of the sliding blocks are equal to the number of the connecting plates.

[0016] By the technical scheme, when the support cage is installed, the locking hole is passed through the locking screw rod, and then the locking nut is tightened to complete the installation, the number of sliding grooves and the number of sliding blocks are equal to the number of connecting plates, and the positions are one-to-one corresponding, when the support cage is installed, as long as the position of the locking hole is aligned with the locking screw rod, the butt joint rod is aligned with the sliding groove, and the butt joint installation is more convenient.

[0017] Further arrangement of the present application is that the butt joint rod is cylindrical, and the bottom opening of the sliding groove is arranged in an "eight" shape.

[0018] By the technical scheme, when the support cage is installed, the butt joint rod is located near the opening of the sliding groove, and can be drawn into the sliding groove along the arc-shaped bottom, so that the installation is simple and convenient.

[0019] Further arrangement of the present application is that the support cage is provided with a protective plate in the form of a ring, and a plurality of dispersion holes are formed in the protective plate.

[0020] When the high-speed gas pulse back-flushing cleaning is performed, the high-speed gas entering the cloth bag will generate high-speed turbulent flow at a position 10-20 cm below the opening of the cloth bag, and generate a large impact force on the side wall of the cloth bag, and after multiple impacts, the cloth bag will be damaged, by the technical scheme, the gas at the position 10-20 cm below the opening of the cloth bag will directly impact the protective plate, and the airflow is blown to the cloth bag along the dispersion holes, so that the direct impact of the high-speed turbulent flow of the gas on the cloth bag is reduced, and the service life of the cloth bag is prolonged.

[0021] Further arrangement of the present application is that a rolling groove is formed in the fixing block, and a ball is arranged in the rolling groove.

[0022] By the technical scheme, when the sliding block slides downward along the fixing block, the resistance is smaller, and the angle of rotation of the cloth bag opening is larger.

[0024] 1. By arranging a plurality of annular fixing blocks and fixing the position of the support cage, the bottom of the cloth bag is connected with the bottom of the support cage, when the high-speed airflow impacts the cloth bag, the bag opening is rotated by the sliding block sliding upward and downward on the fixing block, the bottom of the cloth bag does not rotate, the entire cloth bag is twisted and deformed, the lumps and shells of ash gathered on the outer surface of the cloth bag are loosened, the large lumps of ash directly fall or are broken into small pieces, and then are directly cleaned by the high-speed gas jet, so that the cleaning effect is enhanced, and at the same time, when the cloth bag is impacted by the gas, the part of the bag opening can also move downward by a small distance, so that the tension received by the opening of the cloth bag is reduced, the wear of the opening of the cloth bag is reduced, and the service life of the cloth bag is increased.

[0025] 2. The application relies on the impact force generated by high-speed gas jetting on the cloth bag to make the cloth bag twist, thereby enhancing the technical effect of high-speed gas pulse back blowing cleaning, and the structure is simple, no additional power source is needed, and the manufacturing cost is low.

[0026] 3.

[0042] The working principle of the embodiment is as follows:

[0043] When the cloth bag 4 is installed, the bottom of the cloth bag 4 is put down through the air hole 2a until the sliding block 7a is located at a high position on the fixed block 6, the leakage-proof plate 8 covers the sliding block from the side, then the support cage 5 is put down from the opening of the cloth bag 4, the cloth bag 4 is stretched, the support cage 5 is cylindrical, the cloth bag 4 is also cylindrical after being stretched, the support cage 5 moves downward to a set height, the position of the locking hole 10a is aligned with the locking screw 10b, the docking rod 14 is aligned with the sliding groove 12b, the support cage 5 continues to descend, at this time the docking rod 14 slides into the sliding groove 12b along the "eight" shaped opening of the sliding groove 12b, the support cage 5 and the bottom of the cloth bag 4 are docked, then the locking nut 10c is tightened, the position of the support cage 5 is fixed, at this time the top of the docking cavity 12a has a set distance with the docking piece 13, most of the weight of the support cage 5 is shared by the connecting plate 10 and the partition plate 2, the load of the cloth bag 4 is reduced, the tensile deformation amount of the cloth bag 4 material is reduced, and the service life of the cloth bag 4 is prolonged.

[0044] After a period of exhaust treatment, the outer surface of the cloth bag 4 accumulates dust, some of which coalesces into lumps due to the absorption of some moisture in the air. The surface of the cloth bag 4 needs to be cleaned. The jet pipe 3 sprays a high-speed airflow into the cloth bag 4. The high-speed airflow moves downward along the cloth bag 4 while diffusing. The gas is blown from the inside of the cloth bag 4 to the outside of the cloth bag 4, blowing the dust on the surface of the cloth bag 4 off. Due to the downward impact of the instantaneous high-speed airflow on the cloth bag 4, the cloth bag 4 receives a downward force. At this time, the sliding block 7a slides from the high position of the fixed block 6 to the low position. The sliding block 7a pushes the leakage-proof plate 8 outward. At this time, the opening of the cloth bag 4 rotates by a certain angle. Since the bottom of the cloth bag 4 is connected to the supporting cage 5, it does not rotate with it. The entire cloth bag 4 is twisted. The lumps and shells of dust coalesced on the outer surface of the cloth bag 4 are loosened. Large lumps of dust fall directly or break into small pieces. Then, the high-speed gas is sprayed out directly to clean it. This can directly enhance the cleaning effect of the high-speed gas on the lumps and shells of dust on the outer wall of the cloth bag 4.

[0045] After the completion of the high-speed gas pulse back-blowing cleaning, the cloth bag 4 returns to its original shape due to the stress of the cloth bag 4 material. At the same time, under the action of the torsion spring 9, the leakage-proof plate 8 pushes the sliding block 7a back to the high position of the fixed block 6, completing the resetting of the opening of the cloth bag 4.

[0046] At the same time, when the cloth bag 4 is impacted by the gas, part of the opening of the cloth bag 4 can move downward by a small distance, buffering the impact force of the high-speed gas, reducing the tension on the opening of the cloth bag 4, reducing the wear and tear of the opening of the cloth bag 4, and increasing the service life of the cloth bag 4.

[0047] When the cloth bag 4 needs to be replaced, loosen the locking nut 10c. The supporting cage 5 continues to move downward by a distance. The abutment rod 14 comes into contact with the top of the sliding groove 12b. Then, rotate the supporting cage 5. The abutment rod 14 enters the clamping groove 12c. Continue to rotate the supporting cage 5. The abutment rod 14 enters the connection between the clamping groove 12c and the anti-rotation groove 12d. Then, fix the position of the fixed ring 7. Lift the supporting cage 5. The abutment rod 14 enters the anti-rotation groove 12d. The bottom of the anti-rotation groove 12d comes into contact with the bottom of the abutment rod 14. As the supporting cage 5 rises, the bottom of the cloth bag 4 continues to rise with the supporting cage 5. When the supporting cage 5 moves completely above the partition plate 2, the bottom of the cloth bag 4 also moves out. The turning of the cloth bag 4 is completed. At this time, the outer surface of the cloth bag 4 becomes the inner surface. The harmful dust adsorbed by the cloth bag 4 is wrapped up. Then, the opening of the cloth bag 4 is tied tightly. The next step of recycling the cloth bag 4 can be performed. Then, connect the supporting cage 5 and the bottom of the cloth bag 4. Put in a new cloth bag 4. Reinsert the supporting cage 5 to complete the replacement of the cloth bag 4. During the replacement process, since the outer surface of the cloth bag 4 becomes the inner surface, the dust adsorbed on the cloth bag 4 does not spread into the air in large quantities, reducing the pollution of the working environment.

[0048] When the high-speed gas pulse back-flushing is used, the high-speed gas entering the cloth bag 4 will generate high-speed turbulent flow at the position 10-20 cm below the opening of the cloth bag 4, and generate a great impact force on the side wall of the cloth bag 4. After multiple impacts, the cloth bag 4 will be damaged. By arranging the protection plate 5a on the supporting cage 5, the gas will directly impact the protection plate 5a at the position 10-20 cm below the opening of the cloth bag 4. The airflow is blown to the cloth bag 4 along the dispersion holes 5a1, the direct impact of the high-speed turbulent flow of the gas on the cloth bag 4 is reduced, and the service life of the cloth bag 4 is prolonged.

[0049] It should be noted that the various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be mutually referred to.

[0050] The above description is only a description of the preferred embodiments of the present application, and does not limit the scope of the present application in any way. Any modification or modification made by a person skilled in the art according to the above disclosure is within the protection scope of the claims.
