Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization equipment, and more specifically, to a device for preventing smoke from escaping from a desulfurization absorption tower. Background Art

[0002] Sulfur dioxide emissions are the main cause of global air pollution and acid rain, and the thermal power industry has always been the main source of sulfur dioxide emissions, which makes the flue gas treatment of thermal power plants a top priority for environmental governance. With the increasingly stringent national environmental protection policies, higher requirements are placed on the reliable operation of the desulfurization system of thermal power plants. In the limestone-gypsum wet flue gas desulfurization system, the absorption tower is the core device of the entire flue gas desulfurization system. The flue gas contacts and reacts with the slurry sprayed in the absorption tower, and the sulfur dioxide in the flue gas is absorbed and reacts with the limestone to form gypsum. However, the flue gas flowing along the tower wall in the absorption tower is difficult to be washed by the sprayed limestone slurry, and there is a phenomenon of flue gas "escaping" along the tower wall, which makes it difficult for the entire desulfurization system to meet the ultra-low emission requirements of desulfurization efficiency above 99.6% and sulfur dioxide concentration below 35mg / Nm3. Traditional desulfurization absorption towers have no effective solution to the phenomenon of flue gas "escape" from the tower wall, which has a significant impact on the desulfurization rate. They can only solve this problem by moving the atomizing nozzles of the outermost spray layer outward. However, this method cannot completely solve the phenomenon of flue gas "escape", resulting in the desulfurization rate failing to reach the designed value. At the same time, this method will also increase the disadvantages of scouring and wearing the tower wall and cause major safety hazards such as leakage of the absorption tower.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0030] like Figures 1 to 7 As shown, the utility model provides a device for preventing smoke from escaping from a desulfurization absorption tower, comprising a base 1, the base 1 is fixedly connected to a desulfurization absorption tower 2, and a smoke exhaust port 3 is fixedly arranged on the top of the desulfurization absorption tower 2;

[0031] A flow guiding mechanism is fixedly installed on the inner wall of the desulfurization absorption tower 2;

[0032] The desulfurization mechanism is fixedly installed on the inner wall of the desulfurization absorption tower 2 and is located above the flow guiding mechanism, and a certain distance is maintained between the desulfurization mechanism and the flow guiding mechanism;

[0033] The exhaust mechanism is movably mounted on the outer wall of the desulfurization absorption tower 2, and one end of the exhaust mechanism is located inside the flow guide mechanism;

[0034] Among them, the guide mechanism includes an alloy lining plate 4 fixedly installed on the inner wall of the desulfurization absorption tower 2, the alloy lining plate 4 is located below the desulfurization mechanism and maintains a certain distance, the alloy lining plate 4 and the annular guide plate 5 are fixedly connected, one end of the annular guide plate 5 is fixedly provided with a tooth groove 6, the annular guide plate 5 and one end of the alloy sealing plate 7 are fixedly connected, the other end of the alloy sealing plate 7 is fixedly installed on the inner wall of the desulfurization absorption tower 2, a carbon steel sealing plate 8 is fixedly installed above the alloy sealing plate 7, one end of the carbon steel sealing plate 8 is fixedly connected to the desulfurization absorption tower 2, and the other end is fixedly connected to the annular guide plate 5, and the bottom of the carbon steel sealing plate 8 is fixedly provided with wear-resistant glass flakes 9.

[0035] The staff fixedly installed the device in the desulfurization absorption tower 2, and then rotated the knob 17 to control the direction of the atomizing nozzle 16, and ensured that the atomizing nozzle 16 could perform the desulfurization operation normally without spraying the liquid onto the inner wall of the desulfurization absorption tower 2, and then the desulfurization absorption operation could be started. When the gas rises from the bottom of the desulfurization absorption tower 2, the flue gas is gathered to the center of the tower through the guidance of the annular guide plate 5 and the blocking of the alloy sealing plate 7, so as to prevent the flue gas from rising along the inner wall of the desulfurization absorption tower 2, and the connection between the annular guide plate 5 and the alloy lining plate 4 is protected by the anti-corrosion treatment of the wear-resistant glass flakes 9, and the alloy material has non-corrosive properties in an acidic environment. It has very high resistance to pitting and crevice corrosion, and can effectively resist chloride ion stress corrosion, so that the device has a long service life and reliable operation. When the gas rises, the atomizing nozzle 16 starts to spray liquid to desulfurize and absorb the flue gas. At this time, the flue gas is concentrated in the center of the tower, and the atomizing nozzle 16 will not spray onto the inner wall of the desulfurization absorption tower 2, which can effectively solve the safety risk of the outermost circle spraying and flushing the tower wall, and eliminate the safety hazard of tower wall leakage. Finally, when the operation is completed, the screw plug 11 can be rotated to remove the gasket 12, so that the exhaust hole 10 starts to ventilate and exhaust. The desulfurization absorption tower 2 using this technology is essentially an empty tower, there is no risk of scaling and clogging, and the operation reliability is high.

[0036] By setting the annular guide plate 5 and the alloy sealing plate 7, the flue gas to be treated is gathered to the center, and then sprayed by the atomizing nozzle 16 to complete the desulfurization and absorption of the flue gas. Compared with the traditional device, the device sets a guide mechanism on the tower wall at a certain distance below the atomizing nozzle 16, which plays a role in gathering the flue gas to the center of the tower and eliminates the phenomenon of flue gas escaping along the tower wall. The desulfurization efficiency of the desulfurization tower can be greatly improved, and the problem of spraying and flushing the absorption tower wall can also be solved. In addition, the device has a relatively simple structure, is easy to manufacture and install, has low cost, does not require regular inspection and maintenance, and saves maintenance costs.

[0037] Wherein, a filter plate 19 is fixedly installed inside the desulfurization absorption tower 2;

[0038] The output mechanism is fixedly mounted on the outer wall of the desulfurization absorption tower 2 and is located on the side of the filter plate 19;

[0039] The shaking mechanism is fixedly installed inside the output mechanism;

[0040] Among them, the output mechanism includes a fixed shell 20 fixedly installed on the outer wall of the desulfurization absorption tower 2, the fixed shell 20 is located on the side of the filter plate 19, and a motor 21 is fixedly installed at one end of the fixed shell 20. The output shaft of the motor 21 passes through the interior of the fixed shell 20 and is fixedly connected to a transmission rod 22. The transmission rod 22 is rotatably installed inside the fixed shell 20, and an output block 23 is fixedly sleeved on the outer wall of the transmission rod 22.

[0041] When the desulfurization absorption operation is in progress, the flue gas is absorbed by the liquid sprayed from the atomizing nozzle 16. At this time, the desulfurized gas continues to rise and passes through the filter plate 19. At this time, the macromolecular particles inside the gas are isolated by the filter plate 19. At this time, the staff starts the motor 21. The operation of the motor 21 causes the transmission rod 22 to rotate. The rotation of the transmission rod 22 drives the output block 23 to rotate, thereby hitting the pressing plate 26. When the pressing plate 26 is squeezed, the impact head 25 will hit the fixed shell 20 along the limiting groove 24, so that the vibration is transmitted to the filter plate 19, causing the filter plate 19 to shake to prevent clogging. When the impact is over, the pressing plate 26 is reset through the elastic potential energy of the spring 27, which is convenient for the next shaking operation.

[0042] By setting the filter plate 19, the macromolecular substances in the gas are isolated, and then through the operation of the motor 21, the impact head 25 hits the fixed shell 20, so that the filter plate 19 shakes. Compared with the traditional device, the device isolates the large particles in the gas through the cooperation of the filter plate 19 and the shaking mechanism, and avoids clogging through shaking, thereby reducing air pollution, improving filtration efficiency, and protecting the health of the staff.

[0043] Among them, the desulfurization mechanism includes a mounting plate 13 fixedly installed above the alloy lining plate 4, a circulating water pipe 14 is fixedly installed inside the mounting plate 13, a fixing ring 15 is fixedly sleeved on the outer wall of the circulating water pipe 14, an atomizing nozzle 16 is rotatably installed on the bottom of the fixing ring 15, and a knob 17 is rotatably provided at one end of the fixing ring 15. The knob 17 is responsible for controlling the direction of the atomizing nozzle 16. One end of the circulating water pipe 14 penetrates the outer wall of the desulfurization absorption tower 2 and is fixedly connected to the water inlet 18.

[0044] Rotate the knob 17 to control the direction of the atomizing nozzle 16 and ensure that the atomizing nozzle 16 can perform desulfurization operations normally without spraying liquid onto the inner wall of the desulfurization absorption tower 2. When the gas rises, the atomizing nozzle 16 starts to spray liquid to desulfurize and absorb the flue gas. At this time, the flue gas is concentrated in the center of the tower, and the atomizing nozzle 16 will not spray onto the inner wall of the desulfurization absorption tower 2, which can effectively solve the safety risk of the outermost circle spraying and flushing the tower wall and eliminate the safety hazard of tower wall leakage.

[0045] Among them, the exhaust mechanism includes an exhaust hole 10 fixedly opened on the inner wall of the desulfurization absorption tower 2. The exhaust hole 10 is located inside the interlayer between the annular guide plate 5 and the carbon steel sealing plate 8. There are two groups of exhaust holes 10, and they are located on both sides of the operation of the desulfurization absorption tower 2. Screw plugs 11 are rotatably installed inside the two groups of exhaust holes 10, and a gasket 12 is fixedly installed at one end of the screw plug 11. The gasket 12 is responsible for sealing the exhaust hole 10.

[0046] When the operation is completed, the screw plug 11 can be rotated to remove the gasket 12, so that the exhaust hole 10 begins to ventilate and exhaust.

[0047] Among them, the shaking mechanism includes a limiting groove 24 fixedly installed inside the fixed shell 20. There are two groups of limiting grooves 24, each of which has an impact head 25 movably installed inside. The impact head 25 and the pressing plate 26 are fixedly connected, and the pressing plate 26 and the output block 23 are in contact with each other.

[0048] When the pressing plate 26 is squeezed, the impact head 25 will impact the fixed shell 20 along the limiting groove 24, so that the vibration is transmitted to the filter plate 19, causing the filter plate 19 to shake to prevent clogging.

[0049] There are three groups of flow guiding mechanism, desulfurization mechanism and exhaust mechanism, all of which are fixedly installed inside the desulfurization absorption tower 2 and located below the filter plate 19, and are responsible for multiple desulfurization absorption operations.

[0050] The shaking mechanism further includes a pressing plate 26 fixedly connected to the impact head 25 . The pressing plate 26 and the inner wall of the fixed shell 20 are elastically connected via a spring 27 , and the spring 27 is responsible for the resetting operation of the pressing plate 26 .

[0051] When the collision is over, the pressing plate 26 is reset by the elastic potential energy of the spring 27, so as to facilitate the next shaking operation.

[0052] The working principle and use process of this utility model:

[0053] The staff fixedly installed the device in the desulfurization absorption tower 2, and then rotated the knob 17 to control the direction of the atomizing nozzle 16, and ensured that the atomizing nozzle 16 could perform the desulfurization operation normally without spraying the liquid onto the inner wall of the desulfurization absorption tower 2, and then the desulfurization absorption operation could be started. When the gas rises from the bottom of the desulfurization absorption tower 2, the flue gas is guided by the annular guide plate 5 and blocked by the alloy sealing plate 7, so that the flue gas is gathered toward the center of the tower to prevent the flue gas from rising along the inner wall of the desulfurization absorption tower 2, and the connection between the annular guide plate 5 and the alloy lining plate 4 is protected by the anti-corrosion treatment of the wear-resistant glass flakes 9, and the alloy material has non-corrosive properties in an acidic environment. It has very high resistance to pitting and crevice corrosion, and can effectively resist chloride ion stress corrosion, so that the device has a long service life and reliable operation. When the gas rises, the atomizing nozzle 16 starts to spray liquid to desulfurize and absorb the flue gas. At this time, the flue gas is concentrated in the center of the tower, and the atomizing nozzle 16 will not spray onto the inner wall of the desulfurization absorption tower 2, which can effectively solve the safety risk of the outermost circle spraying and flushing the tower wall, and eliminate the safety hazard of tower wall leakage. Finally, when the operation is completed, the screw plug 11 can be rotated to remove the gasket 12, so that the exhaust hole 10 starts to ventilate and exhaust. The desulfurization absorption tower 2 using this technology is essentially an empty tower, there is no risk of scaling and clogging, and the operation reliability is high.

[0054] When the desulfurization absorption operation is in progress, the flue gas is absorbed by the liquid sprayed from the atomizing nozzle 16. At this time, the desulfurized gas continues to rise and passes through the filter plate 19. At this time, the macromolecular particles inside the gas are isolated by the filter plate 19. At this time, the staff starts the motor 21. The operation of the motor 21 causes the transmission rod 22 to rotate. The rotation of the transmission rod 22 drives the output block 23 to rotate, thereby hitting the pressing plate 26. When the pressing plate 26 is squeezed, the impact head 25 will hit the fixed shell 20 along the limiting groove 24, so that the vibration is transmitted to the filter plate 19, causing the filter plate 19 to shake to prevent clogging. When the impact is over, the pressing plate 26 is reset through the elastic potential energy of the spring 27, which is convenient for the next shaking operation.
