Description

Technical Field

[0001] This invention relates to the field of scrubbing tower technology, and in particular to a multi-tube scrubbing tower. Background Technology

[0002] As a gas purification device, the scrubbing tower is an improvement on the packing layer gas purifier. The scrubbing liquid is atomized into fine droplets through nozzles and sprayed downwards evenly. The dust-laden gas enters from the bottom of the scrubbing tower and flows upwards. The two flow countercurrently and come into contact. The dust particles collide with the water droplets and agglomerate with each other or between the dust particles, greatly increasing their weight. The captured dust settles down by gravity. As the scrubbing liquid settles in the storage tank, a high-concentration solid-phase liquid is formed at the bottom and periodically discharged for further treatment. Some of the scrubbing liquid can be recycled and, together with a small amount of supplementary scrubbing liquid, enters the scrubbing tower from the top nozzles through a circulating pump for scrubbing, thereby reducing the consumption of scrubbing liquid and the amount of secondary wastewater treated. After being scrubbed, the purified gas passes through a demister to remove the fine droplets entrained in the gas and is discharged from the top of the tower.

[0003] To facilitate disassembly, cleaning, maintenance, and replacement, the spray components on existing scrubbing towers are often installed inside the tower in a sliding, detachable manner. When the spray components are disassembled and removed, the water supply pipes connecting them to the spray components are directly exposed to the dusty environment of the scrubbing tower. This makes it easy for dust to enter the pipe components and, guided by the pipe components, enter the spray nozzles, increasing the likelihood of nozzle blockage. Although some equipment is equipped with dust protection components for the pipe components, these components require manual operation before and after use, which is cumbersome and inconvenient. Summary of the Invention

[0004] In view of this, the present invention provides a multi-tube scrubbing tower to solve the problem that when the spray assembly is disassembled and extracted, the water supply pipe assembly inside the scrubbing tower that is connected to the spray assembly is directly exposed to the dusty environment of the scrubbing tower, which makes it easy for dust to enter the pipe assembly and enter the nozzle under the guidance of the pipe assembly, increasing the probability of nozzle blockage.

[0005] This invention provides a multi-tube scrubbing tower, specifically comprising: a scrubbing tower with a square cross-section, and two conical shrouds symmetrically welded to its upper and lower ends. The top of the upper conical shroud is open for discharging treated gas, and a cover plate is screwed onto the opening of the lower conical shroud for settling and filtering the sprayed water. A liquid distribution assembly is welded to the top of the rear wall of the scrubbing tower, and the assembly consists of a transverse main pipe and a row of longitudinal short pipes welded to the transverse main pipe at equal intervals. An electric pump is screwed to the middle of the bottom of the rear wall of the scrubbing tower, with its inlet pipe penetrating the bottom space of the scrubbing tower. A U-shaped metal conduit is welded to the outlet of the electric pump, and the top of the metal conduit is welded to the transverse main pipe. A row of spray pipes is equally spaced and supported at the top of the internal space of the scrubbing tower, and each spray pipe is screwed to the bottom. A row of spray nozzles is suspended from the screen. A row of rectangular countersunk grooves is equidistantly spaced along the front wall of the scrubbing tower. A row of rectangular frames is welded to the rear inner wall of the scrubbing tower at a position corresponding to the height of the row of rectangular countersunk grooves. A row of longitudinal short pipes connects to the row of frames. A cover plate and a sealing plate are welded to the front and rear ends of each spray pipe, respectively. Both the cover plate and the sealing plate are rectangular in structure, and a rectangular sealing ring is adhered and fixed to the outer edge of each cover plate and sealing plate. The sealing plate passes through the rectangular countersunk groove and is inserted into the frame, and the cover plate is also inserted into the rectangular countersunk groove. Multiple sets of vertical positioning shafts are arranged and welded to the rear inner wall of the scrubbing tower near the row of frames. A positioning ring is welded to the middle of each set of vertical positioning shafts, facing the cover plate. An I-shaped force-bearing block is slidably installed on the positioning ring. The cover plate is locked and sealed in the rectangular countersunk groove by four bolts at the four corners. A flue gas inlet pipe is welded to the lower half of the right side wall of the scrubbing tower.

[0006] Furthermore, the sleeve frame is symmetrically fitted with two baffles that slide and insert into each other. Each baffle has a sliding rod welded to its tail end. The protruding sections of the two sliding rods slide and engage with a set of vertical positioning shafts by spring push.

[0007] Furthermore, two ear plates are welded at intervals on the rear half of the spray pipe, and a punch rod is inserted through the two ear plates by spring pushing.

[0008] Furthermore, a sliding shaft is welded to the rear side of the I-shaped force-bearing block, and the sliding shaft and the positioning ring slide through it.

[0009] Furthermore, the I-shaped force-bearing block is symmetrically connected to two connecting rods, the tail ends of which are rotatably connected to the protruding sections of two sliding rods.

[0010] Furthermore, when the spray pipe is slidably inserted into the washing tower, the tail end of the piercing rod makes contact with the I-shaped force-bearing block.

[0011] Furthermore, a water inlet hole is provided through the center of the sealing plate, and the water inlet hole is connected to the spray pipe.

[0012] Furthermore, a circular baffle is welded to the rear end of the sliding shaft, and when the sliding shaft is pushed and driven to slide backward, the circular baffle abuts against the inner rear wall of the washing tower.

[0013] Furthermore, when the sealing plate slides away from the sleeve frame, the two baffles slide and close towards the inside of the sleeve frame to seal the opening of the sleeve frame.

[0014] Furthermore, the wire diameter of the spring on the chuck is six times the wire diameter of the two springs on the vertical positioning shaft.

[0015] Beneficial effects

[0016] 1. In this invention, a row of spray pipes is inserted and supported inside the washing tower in a through sliding installation manner. After the row of cover plates is loosened, the row of spray pipes can be directly pulled out from the washing tower to replace or clean the nozzles on them. Compared with the installation method of directly welding the spray components or using other forms of integrated fixing inside the washing tower, this method can save the trouble of workers entering the washing tower to disassemble, replace and clean the spray components, making the cleaning and disassembly of the spray pipes convenient and quick.

[0017] 2. In this invention, when the sealing plate and the sleeve frame are slidably removed, the two baffles slide and close towards the inside of the sleeve frame to seal the opening of the sleeve frame. This prevents dust and impurities in the flue gas from entering the sleeve frame and forming a top support on the sealing plate when the spray pipe is pulled out for cleaning or replacement, which would affect the sealing fit between the sealing plate and the sleeve frame. Furthermore, dust and impurities in the flue gas can easily enter the liquid distribution assembly, causing the dust to be guided into the nozzle through the liquid distribution assembly, resulting in nozzle blockage.

[0018] 3. In this invention, the two baffles can be automatically switched by the power linkage of the spray pipe's insertion and removal, eliminating the trouble of having to manually operate the two baffles when cleaning or replacing the spray components. This makes it convenient and time-saving to use. Attached Figure Description

[0033] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0034] Example: Please refer to Figures 1 to 9 As shown:

[0035] This invention provides a multi-tube scrubbing tower, including a scrubbing tower 1 with a square cross-section. Two conical shrouds are symmetrically welded to the upper and lower ends of the scrubbing tower 1. The top of the upper conical shroud is open for discharging treated gas, and a cover plate is screwed onto the opening of the lower conical shroud. The lower conical shroud is used to settle and filter the sprayed liquid after use. A liquid distribution assembly 101 is welded to the top of the rear wall of the scrubbing tower 1, and the liquid distribution assembly 101 is composed of a transverse main pipe and a row of longitudinal short pipes welded to the transverse main pipe at equal intervals. An electric pump 3 is screwed onto the middle of the bottom of the rear wall of the scrubbing tower 1, and the inlet pipe of the electric pump 3 passes through it. In the bottom space of the scrubbing tower 1, a U-shaped metal conduit is welded to the outlet of the electric pump 3. The top of the metal conduit is welded to the horizontal main pipe. A row of spray pipes 2 is evenly spaced and supported at the top of the internal space of the scrubbing tower 1. The spray pipes 2 are inserted and supported inside the scrubbing tower 1 using a through-sliding installation. After loosening a row of cover plates 201, the spray pipes 2 can be directly removed from the scrubbing tower 1 to replace or clean the spray nozzles. Compared to directly welding the spray components or using other integrated methods to fix them inside the scrubbing tower 1, this method eliminates the need for workers to enter the scrubbing tower 1 to disassemble, replace, and clean the spray components, thus improving the efficiency of the spray system. The cleaning and disassembly of pipe 2 is convenient and quick, and a row of spray heads is threadedly installed at the bottom of each spray pipe 2; a row of rectangular countersunk grooves are evenly spaced through the front wall of the scrubbing tower 1, and a row of rectangular frame 102 is welded to the rear inner wall of the scrubbing tower 1 at a position corresponding to the height of the row of rectangular countersunk grooves, and a row of longitudinal short pipes is connected to the row of frame 102; a cover plate 201 and a sealing plate 202 are welded to the front and rear ends of the spray pipe 2, respectively. Both the cover plate 201 and the sealing plate 202 are rectangular, and a rectangular sealing ring is glued and fixed to the outer edge of the cover plate 201 and the sealing plate 202; the sealing plate 202 passes through the rectangular countersunk groove and is inserted into the frame 102. The cover plate 201 is inserted into the rectangular countersunk groove; multiple sets of vertical positioning shafts 104 are arranged and welded on the inner rear wall of the washing tower 1 near a row of sleeve frames 102. A positioning ring 105 is welded to the middle position of each set of vertical positioning shafts 104 facing the cover plate 201. An I-shaped force block 4 is slidably installed on the positioning ring 105; the cover plate 201 is locked and sealed in the rectangular countersunk groove by four bolts at the four corners. When the cover plate 201 locks and seals the rectangular countersunk groove, it can also press and seal the sealing plate 202 and the sleeve frame 102 together and achieve the pressing and positioning of the spray pipe 2. When the sealing plate 202 and the sleeve frame 102 are pressed and sealed, the liquid distribution assembly 101 can be connected to the spray pipe 2.On the lower half of the right side wall of the scrubbing tower, a flue gas inlet pipe sleeve 102 is welded, on which two baffles 103 are symmetrically slidably inserted and installed. A sliding rod is welded to the tail end of each baffle 103, and the protruding sections of the two sliding rods slide in cooperation with a set of vertical positioning shafts 104 via spring pushes. On the rear half of the spray pipe 2, two ear plates are welded at intervals, and a punch rod 203 is inserted through each ear plate via spring pushes. A sliding shaft 402 is welded to the rear side of the I-shaped force-bearing block 4, and the sliding shaft 402 slides through and cooperates with the positioning ring 105. A water inlet hole is opened through the center of the sealing plate 202, and the water inlet hole communicates with the spray pipe 2. A circular baffle is welded to the rear end of the sliding shaft 402, and when the sliding shaft 402 is pushed backward, the circular baffle abuts against the rear inner wall of the scrubbing tower 1.

[0036] Among them, the I-shaped force block 4 is symmetrically connected to two connecting rods 401. The tail ends of the two connecting rods 401 are rotatably connected to the protruding sections of the two sliding rods. The two connecting rods 401, the two baffles 103 and the I-shaped force block 4 are connected to form two crank-slider mechanisms. By sliding the I-shaped force block 4 left and right through these two mechanisms, the two baffles 103 can be driven to slide up and down in opposite directions to open and close the sleeve frame 102.

[0037] When the spray pipe 2 is slidably inserted into the scrubbing tower 1, the tail end of the piercing rod 203 pushes against the I-shaped force block 4. Through the piercing rod 203, when the spray pipe 2 is inserted into the scrubbing tower 1, it can push and drive the I-shaped force block 4 to slide backward, thereby driving the two baffles 103 to slide up and down and outward, automatically opening the sleeve frame 102 so that the sealing plate 202 can be inserted and cooperate with the sleeve frame 102. In addition, when the spray pipe 2 is pulled outward to clean and replace the spray head, the piercing rod 203 and the I-shaped force block 4 will make contact. When the force-bearing block 4 separates, the I-shaped force-bearing block 4 loses the pushing and holding force of the push rod 203 and will be driven forward by the two springs on the vertical positioning shaft 104 to reset and control the two baffles 103 to slide inward and automatically close the frame 102. This allows the two baffles 103 to be automatically switched on and off by the linkage of the spouting and disassembly of the spray pipe 2, saving the trouble of manually applying force to slide the two baffles 103 when disassembling and assembling the spray assembly for cleaning and maintenance. It is convenient and time-saving to use.

[0038] When the sealing plate 202 and the sleeve frame 102 are slidably pulled apart, the two baffles 103 slide and close towards the inside of the sleeve frame 102 to block the opening of the sleeve frame 102. This prevents dust and impurities in the flue gas from entering the sleeve frame 102 when the spray pipe 2 is pulled out for cleaning or replacement, thus preventing them from forming a top support on the sealing plate 202 and affecting the sealing fit between the sealing plate 202 and the sleeve frame 102. In addition, dust and impurities in the flue gas can easily enter the liquid distribution assembly 101, causing the dust to be guided into the nozzle through the liquid distribution assembly 101 and causing the nozzle to become clogged.

[0039] The wire diameter of the spring on the puncture rod 203 is six times that of the two springs on the vertical positioning shaft 104. This ensures that the spring force on the puncture rod 203 is three times the total spring force of the two springs on the vertical positioning shaft 104. Furthermore, in its initial state, the puncture rod 203 protrudes forward and supports the front of the sealing plate 202 (refer to...). Figure 5 When the sealing plate 202 is inserted into the sleeve frame 102, the piercing rod 203 will first push into contact with the I-shaped force-bearing block 4. Because the large pushing force of the spring on the piercing rod 203 can resist the indirect elastic force exerted on the I-shaped force-bearing block 4 by the two springs on the vertical positioning shaft 104, the two baffles 103 are pre-push open before the sealing plate 202 reaches the sleeve frame 102, preventing the two baffles 103 from obstructing the insertion and engagement of the sealing plate 202 and the sleeve frame 102. Furthermore, when the two baffles 103 are fully opened, and the circular baffle at the rear end of the sliding shaft 402 abuts against the rear inner wall of the washing tower 1, the piercing rod 203... The rod 203 can be pushed forward by the I-shaped force block 4 to compress the spring on it, allowing the spray pipe 2 to slide forward continuously, so that the sealing plate 202 and the sleeve frame 102 can abut and seal. In addition, when the spray pipe 2 is removed and disassembled, the large pushing force of the spring on the stick rod 203 can resist the spring force indirectly acting on the I-shaped force block 4 by the two springs on the vertical positioning shaft 104, temporarily keeping the two baffles 103 in the outward sliding open state, ensuring that the two baffles 103 only begin to slide inward and close after the sealing plate 202 is removed from the sleeve frame 102, thus avoiding hindering the removal of the sealing plate 202 and the sleeve frame 102.

[0040] The specific usage and function of this embodiment: When the present invention is used, the waste smoke and exhaust gas to be treated enter the scrubbing tower 1 through the flue gas inlet pipe and rise upwards. The electric pump 3 can pressurize and guide the dust removal liquid in the bottom cone hood through the metal conduit and the liquid distribution assembly 101 to a row of spray pipes 2 and atomize it through multiple rows of nozzles. When the waste smoke and exhaust gas rise to the top space of the scrubbing tower 1, the multiple rows of nozzles can spray and remove dust. After dust removal, the flue gas is discharged from the top opening of the upper cone hood. In addition, the liquid dripped after spraying is collected in the bottom cone hood. The bottom cone hood can settle and filter the sprayed liquid after use, and the electric pump 3 can circulate and pump it for use.

[0041] A row of spray pipes 2 is inserted and supported inside the washing tower 1 in a through sliding installation. After the row of cover plates 201 is loosened, the row of spray pipes 2 can be directly pulled out from the washing tower 1 to replace or clean the spray nozzles. When the cover plate 201 locks and seals the rectangular countersunk groove, it can also press and seal the sealing plate 202 and the sleeve frame 102 together and achieve the pressing and positioning of the spray pipes 2. When the sealing plate 202 and the sleeve frame 102 are pressed and sealed, the liquid distribution assembly 101 can be connected to the spray pipes 2.

[0042] Two baffles 103 slide inward toward the inside of the sleeve frame 102 to seal the opening of the sleeve frame 102, preventing dust and impurities in the flue gas from entering the sleeve frame 102 and forming a top support on the sealing plate 202 when the spray pipe 2 is pulled out for cleaning or replacement. This would affect the sealing fit between the sealing plate 202 and the sleeve frame 102. Furthermore, the two connecting rods 401, the two baffles 103, and the I-shaped force block 4 are connected to form two crank-slider mechanisms. By sliding the I-shaped force block 4 left and right through these two mechanisms, the two baffles 103 can slide up and down in opposite directions to open and close the sleeve frame 102. Through the push rod 203, the spray pipe 2 is inserted into the scrubbing tower 1. During installation, the push-driven I-shaped force block 4 can slide backward, which in turn drives the two baffles 103 to slide outward and up and down, automatically opening the frame 102 so that the sealing plate 202 can be inserted and fitted with the frame 102. In addition, when the spray pipe 2 is pulled outward to clean and replace the nozzle, the piercing rod 203 separates from the I-shaped force block 4. The I-shaped force block 4 loses the pushing and holding force of the piercing rod 203 and will be pushed back by the two springs on the vertical positioning shaft 104, which will drive it to slide forward and reset, and control the two baffles 103 to slide inward and automatically close the frame 102. This allows the two baffles 103 to be automatically switched on and off by the linkage of the spray pipe 2's insertion and removal power.

[0043] The wire diameter of the spring on the poking rod 203 is six times the wire diameter of the two springs on the vertical positioning shaft 104. This ensures that the spring force on the poking rod 203 is three times the total spring force of the two springs on the vertical positioning shaft 104. Furthermore, in its initial state, the poking rod 203 protrudes forward and supports the front of the sealing plate 202 (refer to...). Figure 5 When the sealing plate 202 is inserted into the sleeve frame 102, the piercing rod 203 will first push into contact with the I-shaped force-bearing block 4. Because the large pushing force of the spring on the piercing rod 203 can resist the indirect elastic force exerted on the I-shaped force-bearing block 4 by the two springs on the vertical positioning shaft 104, the two baffles 103 are pre-push open before the sealing plate 202 reaches the sleeve frame 102, preventing the two baffles 103 from obstructing the insertion and engagement of the sealing plate 202 and the sleeve frame 102. Furthermore, when the two baffles 103 are fully opened, and the circular baffle at the rear end of the sliding shaft 402 abuts against the rear inner wall of the washing tower 1, the piercing rod 203... The rod 203 can be pushed forward by the I-shaped force block 4 to compress the spring on it, allowing the spray pipe 2 to slide forward continuously, so that the sealing plate 202 and the sleeve frame 102 can abut and seal. In addition, when the spray pipe 2 is removed and disassembled, the large pushing force of the spring on the stick rod 203 can resist the spring force indirectly acting on the I-shaped force block 4 by the two springs on the vertical positioning shaft 104, temporarily keeping the two baffles 103 in the outward sliding open state, ensuring that the two baffles 103 only begin to slide inward and close after the sealing plate 202 is removed from the sleeve frame 102, thus avoiding hindering the removal of the sealing plate 202 and the sleeve frame 102.
