Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization equipment, in particular to a desulfurization pipeline filtering device. Background Art

[0002] Desulfurization generally refers to the process of removing sulfides from combustion exhaust gases. Desulfurization usually involves contacting sulfur-containing exhaust gases with liquid desulfurizers to convert sulfides into water-soluble compounds. Desulfurization pipeline filtration equipment usually refers to filters installed on the desulfurization system pipelines to filter solid particles and other impurities.

[0003] During the desulfurization process, filters are usually installed in the pipeline to filter solid particles. The filters can use different filter media, such as filter screens, filter elements, and filter bags. The appropriate filter is selected according to the size and properties of the solid particles. The solid particles will be intercepted by the filter, thereby preventing them from entering the desulfurizer spray pipe of the desulfurization equipment.

[0004] Existing desulfurization pipeline filtering equipment usually only adds a filter in the pipeline to achieve the particle filtering effect, but the filtering effect of the filter is usually poor. In addition, due to the single filter, long-term filtering of particles may cause some filter holes to be blocked, which may affect the circulation, spraying and reaction of the desulfurizer, thereby reducing the desulfurization efficiency and desulfurization effect. Therefore, a desulfurization pipeline filtering equipment is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and address the problems existing in the prior art equipment, the utility model proposes a desulfurization pipeline filtering device.

[0006] The technical solution adopted by the utility model to solve its technical problems is a desulfurization pipeline filtering device, including: a desulfurization tank, three liquid outlet pipes are embedded on the lower end shaft body of one side of the desulfurization tank, one side of the three liquid outlet pipes are all sleeved with a liquid stop valve, one side of the three liquid stop valves are all embedded with a threaded sleeve, one side of the three threaded sleeves are all embedded with a filter tube, one side of the three filter tubes is fixed with a first liquid inlet pipe, one side of the first liquid inlet pipe is fixed with a second liquid inlet pipe, the second liquid inlet pipe is fixedly connected to the upper end shaft body of the desulfurization tank near the liquid outlet pipe, the upper end shaft bodies of the three filter tubes are penetrated by a second transmission shaft, the upper ends of the three second transmission shafts are fixed with a first transmission shaft, the upper ends of the first transmission shafts are fixed with a motor, the lower end faces of the three second transmission shafts are fixed with a gear box, and the three gears are fixed with a gear box. A rotating rod is fixed at the center of one side of the wheel box, and sliding grooves are provided on both sides of the middle part of the three filter tubes. Filter barrels are sleeved in the three filter tubes, and first holes are evenly provided on the outer shafts of the three filter barrels. Collecting barrels are fixed at the lower ends of the three rotating rods, and second holes are evenly provided on the outer shafts of the three collecting barrels. Rotating shafts are fixed on the lower shafts of one side of the three collecting barrels, and reflux baffles are sleeved on the three rotating shafts. Through the three filter tubes and the liquid stop valve, when the filter tube is blocked by particulate matter and the desulfurization effect is poor, the filter tube can be cleaned in batches through the liquid stop valve, and the collecting barrel is driven to rotate continuously by the motor, and the particulate matter is collected into the collecting barrel through the reflux baffle, so as to extend the service life of the filter tank and facilitate the cleaning in the pipeline.

[0007] Preferably, the three filter tubes are at the same height on the outer shaft of the desulfurization tank. The three filter tubes are at the same height to avoid different pressures at the three liquid outlets. At the same time, the setting of the three filter tubes facilitates cleaning of the filter tubes without stopping the desulfurization work.

[0008] Preferably, the second liquid inlet pipe is perpendicular to the outer upper shaft of the desulfurization tank at a constant height, and the second liquid inlet pipe is vertically distributed at a constant ratio on the outer shaft of the desulfurization tank, which is conducive to desulfurizing the sulfur-containing gas evenly in three layers and enhancing the desulfurization effect.

[0009] Preferably, sliders are fixed on both sides of the middle part of the three filter barrels, and the sliders are slidably set in the slide groove. The sliders are embedded in the slide groove, which facilitates the enhancement of the stability of the filter barrel on the one hand and the disassembly of the filter barrel for cleaning on the other hand.

[0010] Preferably, a support rod is fixed at the center of one side of the motor, and one side of the support rod is fixedly connected to the lower shaft of the first liquid inlet pipe, so that the stability of the motor can be increased by the support rod.

[0011] Preferably, threaded sleeves are provided on both sides of the three filter tubes, and the threaded sleeves on both sides facilitate the removal of the filter tubes and the cleaning of particulate matter in the filter tubes.

[0012] The utility model is beneficial in that: through the three filter tubes and the liquid stop valve, on the one hand, the circulation of the desulfurizer in the desulfurization tank is increased, and at the same time, the filter tube can be cleaned of waste in batches through the liquid stop valve, and the collection barrel is driven to rotate continuously in the filter barrel by the rotation of the motor, so that the particles in the filter barrel are collected into the collection barrel through the internal hinged reflux baffle during rotation, so as to avoid the accumulation of particles in the hole groove of the filter barrel due to long-term filtering of the filter barrel, resulting in poor filtering effect, affecting the circulation and spraying of the desulfurizer, thereby reducing the desulfurization effect and desulfurization efficiency.

[0022] The desulfurization tank 1 discharges the desulfurizer from three liquid outlet pipes 2, and discharges it to the second liquid inlet pipe 10 through the first liquid inlet pipe 9, so as to be discharged from the upper part of the desulfurization tank 1 and fully merged with the sulfur-containing gas, thereby desulfurizing. When it is necessary to clean the particles accumulated by long-term filtration, the liquid stop valve 3 can be closed in turn to disassemble and clean the corresponding filter tube 5 through the threaded sleeve 4. During the desulfurization process, the desulfurizer passes through the filter tube 5, and the larger particles are filtered into the filter barrel 12 through the filter barrel 12 in the filter tube 5. A continuously rotating collection barrel 18 is arranged inside the filter barrel 12, which is rotated by the motor 7, thereby driving the first transmission shaft 6 to rotate, so that the second transmission shaft 15 rotates, and the gear box 14 drives the rotating rod 13 and the collection barrel 18 to rotate. The rotating rod 13 passes through the center of the filter barrel 12. When the collecting barrel 18 rotates, the desulfurizer in the filter tube 5 will push open the reflux baffle 20, so that the particulate matter filtered in the filter barrel 12 is collected in the collecting barrel 18. At the same time, the reflux baffle 20 prevents the particles from flowing back into the filter barrel 12, thereby forming a particle collection effect. The appropriate desulfurizer is discharged from the collecting barrel 18 through the second hole groove 19, and then discharged from the filter tube 5 through the first hole groove 17 to transport the desulfurizer to the first liquid inlet pipe 9. The desulfurizer is sprayed downward at the upper end of the desulfurization tank 1 through the second three-way second liquid inlet pipe 10, so as to avoid long-term filtration of particles causing blockage of the first hole groove 17, thereby affecting the circulation and spraying of the desulfurizer, thereby improving the desulfurization efficiency and desulfurization effect.

[0023] The three filter tubes 5 are at the same height on the outer shaft of the desulfurization tank 1. The three filter tubes 5 are at the same height to avoid different pressures at the three liquid outlets. At the same time, the three filter tubes 5 are convenient for closing the stop valve 3 in sequence when the desulfurization pipeline effect is not good. At the same time, the filter tube 5 that closes the stop valve 3 is disassembled through the threaded sleeve 4 to complete the cleaning work of the filter tube 5 without affecting the desulfurization work. The second liquid inlet pipe 10 is perpendicular to the outer upper end shaft of the desulfurization tank 1 at a constant height. The second liquid inlet pipe 10 is vertically distributed at a constant ratio on the outer shaft of the desulfurization tank 1. A three-layer spray pipe is formed by the second liquid inlet pipe 10, so that the desulfurizer is fully combined with the sulfur-containing gas for desulfurization, thereby increasing the desulfurization effect.

[0024] Slide blocks 16 are fixed on both sides of the middle part of the three filter barrels 12. The slide blocks 16 are slidably set in the slide groove 11. The slide blocks 16 are embedded in the slide groove 11. On the one hand, it is convenient to enhance the stability of the filter barrel 12, and on the other hand, it is convenient to disassemble the filter barrel 12 for cleaning. A support rod 8 is fixed at the center of one side of the motor 7. One side of the support rod 8 is fixedly connected to the lower shaft body of the first liquid inlet pipe 9. The support rod 8 is convenient to increase the stability of the motor 7. Threaded sleeves 4 are sleeved on both sides of the three filter tubes 5. The threaded sleeves 4 on both sides are convenient to disassemble the filter tubes 5. At the same time, the filter barrel 12 is slid out through the slide groove 11, and then the collection barrel 18 is taken out, and the cleaning inside the collection barrel 18 is carried out.

[0025] Working principle: When desulfurization is carried out, the desulfurization tank 1 discharges the desulfurizer from the three liquid outlet pipes 2, and discharges it from the first liquid inlet pipe 9 to the second liquid inlet pipe 10, so as to be discharged from the upper part of the desulfurization tank 1 and fully merge with the sulfur-containing gas, thereby desulfurization. When it is necessary to clean the particles accumulated by long-term filtration, the stop valve 3 can be closed in turn to disassemble and clean the corresponding filter tube 5 through the threaded sleeve 4. During the desulfurization process, the desulfurizer passes through the filter tube 5, and the filter barrel 12 in the filter tube 5 filters the larger particles into the filter barrel 12. The filter barrel 12 is provided with a continuously rotating collection barrel 18, which is rotated by the motor 7 to enter the filter barrel 12. And drive the rotating rod 13 and the collecting barrel 18 to rotate. When the collecting barrel 18 rotates, the desulfurizer in the filter tube 5 will push open the reflux baffle 20, so that the particulate matter filtered out of the filter barrel 12 is collected in the collecting barrel 18, and the suitable desulfurizer is discharged from the collecting barrel 18 through the second hole groove 19, and then discharged from the filter tube 5 to the first liquid inlet pipe 9 through the first hole groove 17. The desulfurizer is sprayed downward at the upper end of the desulfurization tank 1 through the second three-way liquid inlet pipe 10, so as to avoid the first hole groove 17 being blocked by long-term filtering of particles, thereby affecting the circulation and spraying of the desulfurizer, thereby improving the desulfurization efficiency and desulfurization effect.
