Description

Technical Field

[0001] The utility model relates to the technical field of coal gas purification, and more specifically, to a wet dust collector for purifying coal gas. Background Art

[0002] my country is a major steel producer. Steel slag is a solid waste produced in the steelmaking process. Steel slag often produces a lot of dusty flue gas during the heat treatment process. In order to protect the environment and improve the working conditions of workers, dust must be controlled. Traditional wet electrostatic precipitators are widely used in the fields of steel, coal chemical industry, etc. Wet dust collectors are devices that make dusty gas and liquid come into close contact, use the inertial collision of water droplets and particles, or use the full mixing of water and dust, and other effects to capture particles, or make particles larger, or keep them in a fixed container to achieve the effect of water and dust separation. Traditional wet electrostatic precipitators are usually installed in the entire operation. The same amount of water is used to clean and capture particles during operation, which will result in excessive water being used and waste of water resources when the amount of gas entering is small. Operating all spray layers at the same time will also cause the spray liquid to cover the surface of the particles unevenly, thereby reducing the cleaning efficiency. During the entire operation, it is necessary to continuously provide water and operate all spray layers, which increases the energy consumption of equipment such as pumps. Since all spray layers are in the open state during the entire operation, this means that all spray layers need to be maintained and cleaned, which ultimately increases the maintenance cost of the equipment, and therefore needs to be improved and optimized.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] like Figures 1 to 7 As shown, the utility model provides a wet dust collector for purifying coal gas, comprising a dust collector 1, an air intake bin 2 is fixedly installed on the front of the dust collector 1, two limit blocks 37 are fixedly installed on the inner wall of the air intake bin 2, an operation box 3 is fixedly installed on the top of the air intake bin 2, a regulating chamber 4 is fixedly installed on the top of the dust collector 1, an exhaust pipe 5 is fixedly installed on the top of the regulating chamber 4, a baffle plate 23 is hingedly installed in the air intake bin 2, a spring 24 is fixedly installed on the outer wall of the baffle plate 23, and the top of the spring 24 is fixedly connected to the top inner wall of the air intake bin 2;

[0032] A regulating mechanism, fixedly mounted on the top of the air inlet bin 2;

[0033] The transmission mechanism is arranged inside the air intake bin 2;

[0034] The spraying mechanism is arranged outside the dust collector 1;

[0035] The stirring mechanism is arranged inside the dust collector 1;

[0036] Among them, the regulating mechanism includes a first rack 25 slidably installed on the top of the air inlet chamber 2. The bottom end of the first rack 25 is fixedly connected to the top of the baffle plate 23. Two fixed blocks 32 are fixedly installed on the top of the air inlet chamber 2. Support rods 26 are respectively rotatably installed in the two fixed blocks 32. Third gears 27 are respectively fixedly installed on the outer walls of the two support rods 26. Discs 28 are respectively fixedly installed on the corresponding sides of the two support rods 26. Connecting rods 29 are respectively hingedly installed on the outer walls of the two discs 28. A second rack 31 is arranged on the top of the air inlet chamber 2. The second rack 31 extends into the air inlet chamber 2. The second rack 31 and the first rack 25 are respectively engaged with the corresponding third gears 27.

[0037] In actual application, under the action of the limit block 37, the baffle plate 23 in the air inlet chamber 2 is inclined at a certain angle. Then, the coal gas containing dust is passed into the dust collector 1 through the gap between the baffle plate 23 and the air inlet chamber 2. Then, the first motor 15 is started. The output shaft of the first motor 15 drives the first gear 16 to rotate. The first gear 16 and the second gear 17 are engaged, providing power for the rotation of the rotating rod 18. The rotating rod 18 drives the stirring blade 19 and the C-shaped block 20 to rotate, which can effectively stir the mixed liquid in the dust collector 1 sufficiently. At the same time, the rotating C-shaped block 20 can scrape off the alkaline particles attached to the inner wall. The coal gas in the dust collector 1 first passes evenly through the air flow holes 34 on the filter plate 13. Then, the water pump 7 is started. With the cooperation of the first hollow pipe 8 and the second hollow pipe 9, the chemical agent mixed liquid in the dust collector 1 is sprayed on the coal gas through the nozzle 12. When the coal gas passes through the demisting plate 14, the liquid droplets therein collide with the demisting plate and deposit, improving the dust removal effect. When the amount of coal gas increases, the coal gas entering the air inlet chamber 2 forms an upward force on the baffle plate 23, pushing the first rack 25 to move upward. The first rack 25 is engaged with the corresponding third gear 27. The third gear 27 drives the corresponding support rod 26 to rotate. The support rod 26 drives the corresponding disc 28 to rotate. The disc 28 drives the strip-shaped bracket 30 to move under the action of the corresponding connecting rod 29, making the pipeline of the second hollow pipe 9 in contact with the inner wall of the strip-shaped bracket 30 unobstructed, thus forming a double spraying layer to achieve a sufficient dust removal effect. When the amount of incoming coal gas reaches the maximum limit, it pushes the baffle plate 23 to move upward continuously, causing the baffle plate 23 to drive the second rack 31 to move together. The second rack 31 is engaged with the corresponding third gear 27. The third gear 27 drives the corresponding support rod 26 to rotate. The support rod 26 drives the corresponding disc 28 to rotate. The disc 28 drives the L-shaped bracket 11 to move under the action of the corresponding connecting rod 29, making the pipeline of the second hollow pipe 9 in contact with the inner wall of the L-shaped bracket 11 unobstructed, thereby forming a triple spraying layer.

[0038] By making the gear rod 1 25 mesh with the gear 3 27 according to the amount of gas entering the air inlet bin 2, the gear 3 27 drives the support rod 26 to rotate, and the support rod 26 drives the disc 28 to rotate. The disc 28 moves under the action of the connecting rod 29, so that the hollow pipe 29 in contact with the inner wall of the bracket is unobstructed, thereby increasing the spray layer. Compared with the traditional device, the adaptive opening of the spray layer can adjust the flow rate of the spray liquid according to the amount of gas entering, so that the spray liquid evenly covers the surface of the particles. This can improve the cleaning efficiency of the wet dust collector, reduce the residual particulate matter, and avoid excessive water being used and wasted. This can effectively save water resources, bring considerable water-saving effects in long-term operation, and avoid unnecessary energy consumption. When the amount of gas entering is small, closing a part of the spray layer can reduce the workload of the pump, further reduce energy consumption, and thus reduce costs.

[0039] Among them, a motor 21 is fixedly installed on the inner wall of the top of the regulating chamber 4.

[0040] A steering mechanism, arranged inside the regulating chamber 4;

[0041] The steering mechanism includes a gear six 22 fixedly mounted on the motor two 21 , a gear five 35 fixedly mounted on the outer wall of the exhaust pipe 5 , and the gear five 35 meshes with the gear six 22 .

[0042] The staff first inquires about the local wind direction at that time, and then starts motor 21. The output shaft of motor 21 drives gear 6 22 to rotate, gear 6 22 and gear 5 35 are engaged, gear 6 22 drives gear 5 35 to rotate, and gear 5 35 drives exhaust pipe 5 to rotate according to the wind direction, so that the exhaust gas is consistent with the movement direction of the wind.

[0043] By starting motor 21, the output shaft of motor 21 drives gear 6 22 to rotate, gear 6 22 and gear 5 35 engage, gear 6 22 drives gear 5 35 to rotate, and gear 5 35 drives exhaust pipe 5 to rotate according to the wind direction. Compared with the traditional device, the rotating exhaust pipe 5 makes the exhausted gas consistent with the movement direction of the wind, utilizes the natural wind force to promote the diffusion and discharge of smoke, reduces the dependence on mechanical exhaust equipment, thereby reducing energy consumption and operating costs, and improves the practicality of the device. At the same time, it can also avoid the exhaust pipe 5 being fixed. When the wind direction changes, the smoke may be blown back to residential areas or other sensitive areas, causing secondary pollution.

[0044] Among them, a strip-shaped bracket 30 is hinged and installed on the right outer wall of the corresponding connecting rod 29, and an L-shaped bracket 11 is hinged and installed on the left outer wall of the corresponding connecting rod 29. There are two mounting blocks 10 arranged outside the dust collector 1. The strip-shaped bracket 30 and the L-shaped bracket 11 are slidably connected to the corresponding mounting blocks 10. There are three second hollow tubes 9 arranged outside the dust collector 1. The top ends of the second hollow tubes 9 extend into the dust collector 1 and are fixedly connected to the dust collector 1. The corresponding two second hollow tubes 9 respectively penetrate through the two mounting blocks 10 and are fixedly connected to the mounting blocks 10. The tops of the strip-shaped bracket 30 and the L-shaped bracket 11 are respectively in contact with the inner walls of the corresponding second hollow tubes 9.

[0045] Among them, the spraying mechanism includes three spraying components. The spraying component includes an L-shaped block 6 arranged outside the dust collector 1. A water pump 7 is fixedly installed inside the L-shaped block 6. The water inlet end of the water pump 7 is fixedly installed with a first hollow tube 8. The top end of the first hollow tube 8 is fixedly connected to the outer wall of the dust collector 1. The water outlet end of the water pump 7 is fixedly connected to the bottom end of the second hollow tube 9. Eight groups of nozzles 12 are fixedly installed on the outer wall of the second hollow tube 9.

[0046] By starting the water pump 7, with the cooperation of the first hollow tube 8 and the second hollow tube 9, the chemical agent mixture in the dust collector 1 is sprayed on the gas through the nozzles 12, which can reduce the concentration of particulate matter, adsorb and capture the particulate matter in the gas, cause the particulate matter to settle or be brought into the liquid pool of the dust collector, thereby reducing the concentration of particulate matter in the air flow and achieving the purpose of dust removal.

[0047] Among them, the stirring mechanism includes a first motor 15 fixedly installed on the inner wall of the bottom of the dust collector 1. A first gear 16 is fixedly installed on the output shaft of the first motor 15. A rotating plate 36 is fixedly installed inside the dust collector 1. A rotating rod 18 is rotatably installed on the top of the rotating plate 36. The bottom end of the rotating rod 18 extends outside the rotating plate 36. Stirring blades 19 are fixedly installed on the outer wall of the rotating rod 18. A second gear 17 is fixedly installed on the outer wall of the rotating rod 18. The second gear 17 meshes with the first gear 16. A U-shaped block 20 is rotatably installed on the outer wall of the rotating rod 18.

[0048] By starting the first motor 15, the output shaft of the first motor 15 drives the first gear 16 to rotate. The first gear 16 and the second gear 17 are meshed, providing power for the rotation of the rotating rod 18. The rotating rod 18 drives the stirring blades 19 and the U-shaped block 20 to rotate, which can effectively stir the mixture liquid in the dust collector 1, make the reaction between chemical agents more sufficient, improve the reaction efficiency, avoid the waste of agents. At the same time, since the alkaline particles in the solution are easily attached to the inner wall of the dust collector 1 and the top of the rotating plate 36, the rotating U-shaped block 20 can scrape off the attached alkaline particles, thereby effectively improving the service life of the device.

[0049] Among them, a filter plate 13 is fixedly installed on the inner wall of the dust collector 1, and air flow holes 34 are arranged on the filter plate 13.

[0050] By setting the filter plate 13, the coal gas is gathered in the air flow holes 34 on the filter plate 13 and passes evenly, which prevents part of the coal gas from overflowing along the inner wall of the dust collector 1, thereby preventing the formation of a gas corridor and improving the dust removal efficiency of the coal gas.

[0051] A demister plate 14 is fixedly mounted on the inner wall of the dust collector 1, and the demister plate 14 is made of glass fiber material.

[0052] By setting up the demister plate 14, when the coal gas passes through, the droplets or particles therein will collide with its surface due to inertia. Larger droplets or particles will directly collide with the demister plate and deposit due to their greater inertia, thereby improving the dust removal effect. In addition, by using glass fiber material, it has better corrosion resistance, high temperature stability and higher capture efficiency.

[0053] The heights of the three hollow tubes 9 are arranged from low to high, and the three spray assemblies are spaced evenly and surround the outside of the dust collector 1.

[0054] By setting the hollow tubes 9 of different heights, a multi-layer spraying layer is formed in the dust collector 1, so that the reactant can be sprayed evenly into the coal gas, and more contact is generated between the coal gas and the reactant, thereby extending the reaction time between the coal gas and the reactant and avoiding the situation of insufficient or excessive local spraying.

[0055] The working principle and use process of this utility model:

[0056] In practical applications, under the action of the limit block 37, the baffle plate 23 in the air inlet chamber 2 is inclined at a certain angle. Then, the dust-containing coal gas is introduced into the interior of the dust collector 1 through the gap between the baffle plate 23 and the air inlet chamber 2. Then, the first motor 15 is started. The output shaft of the first motor 15 drives the first gear 16 to rotate. The first gear 16 meshes with the second gear 17, providing power for the rotation of the rotating rod 18. The rotating rod 18 drives the stirring blade 19 and the U-shaped block 20 to rotate, which can effectively stir the mixed liquid in the dust collector 1 sufficiently. At the same time, the rotating U-shaped block 20 can scrape off the alkaline particles adhering to the inner wall. The coal gas in the dust collector 1 first uniformly passes through the air flow holes 34 on the filter plate 13. Then, the water pump 7 is started. With the cooperation of the first hollow pipe 8 and the second hollow pipe 9, the chemical agent mixed liquid in the dust collector 1 is sprayed onto the coal gas through the nozzle 12. When the coal gas passes through the demisting plate 14, the droplets in it collide with the demisting plate and deposit, improving the dust removal effect. When the amount of coal gas increases, the coal gas entering the air inlet chamber 2 forms an upward force on the baffle plate 23, pushing the first rack 25 upward. The first rack 25 meshes with the corresponding third gear 27. The third gear 27 drives the corresponding support rod 26 to rotate. The support rod 26 drives the corresponding disc 28 to rotate. The disc 28 drives the strip-shaped bracket 30 to move under the action of the corresponding connecting rod 29, making the pipeline of the second hollow pipe 9 in contact with the inner wall of the strip-shaped bracket 30 unobstructed, thereby forming a double spraying layer to achieve a sufficient dust removal effect. When the amount of incoming coal gas reaches the maximum limit, it pushes the baffle plate 23 to move upward continuously, causing the baffle plate 23 to drive the second rack 31 to move together. The second rack 31 meshes with the corresponding third gear 27. The third gear 27 drives the corresponding support rod 26 to rotate. The support rod 26 drives the corresponding disc 28 to rotate. The disc 28 drives the L-shaped bracket 11 to move under the action of the corresponding connecting rod 29, making the pipeline of the second hollow pipe 9 in contact with the inner wall of the L-shaped bracket 11 unobstructed, thus forming a triple spraying layer.

[0057] The staff first query the local wind direction at that time, and then start the second motor 21. The output shaft of the second motor 21 drives the sixth gear 22 to rotate. The sixth gear 22 meshes with the fifth gear 35. The sixth gear 22 drives the fifth gear 35 to rotate. The fifth gear 35 drives the exhaust pipe 5 to move and rotate according to the wind direction, so that the exhausted gas moves in the same direction as the wind.
