Description

Technical Field

[0001] The present invention belongs to the technical field of flue gas desulfurization, and specifically, it relates to an optimized control unit for the oxidation air volume of a desulfurization fan. Background Art

[0002] Except for carbon dioxide, the dust, sulfur, nitrogen oxides, and carbon monoxide contained in the flue gas of coal-fired boilers are all air pollutants that can damage the human body, environment, and ecosystem. During the desulfurization process, a desulfurization control unit is commonly used. The desulfurization control unit belongs to ecological environmental protection construction. The desulfurization control unit is mainly used for flue gas desulfurization treatment of facilities such as coal-fired power plants to reduce sulfur dioxide emissions and is part of ecological environmental protection construction. During the desulfurization process, a desulfurization slurry is commonly used. The desulfurization slurry is a paste-like substance made by mixing desulfurization absorbents such as limestone with water and is in a paste form for wet flue gas.

[0003] A high-efficiency utilization system for limestone slurry in a desulfurization system proposed in Chinese Patent CN221815754U includes a desulfurization tower main body, a slurry circulation pump, a support base, and a top spray layer. A slurry pool is provided inside the support base. The slurry circulation pump is provided with a liquid outlet pipe and a liquid suction pipe extending to the bottom inside the slurry pool. A slurry supply pipe is provided on one side of the top spray layer. The slurry supply pipe is provided with a slurry supply pipeline communicating with the liquid suction pipe. The slurry supply pipe is provided with a second control valve, and the slurry supply pipeline is provided with a third control valve. The liquid outlet pipe is provided with a plurality of spray pipes extending to the middle inside the top spray layer. Compared with the prior art, the advantages of this device are as follows: The high-efficiency utilization process of limestone slurry in this desulfurization system can solve the problem that when the unit load and coal sulfur content fluctuate greatly, the sulfur dioxide content in the clean flue gas exceeds the standard instantaneously. It can not only make the fresh slurry be utilized efficiently and rapidly but also reduce the calcium carbonate content in the gypsum.

[0004] Currently, during the operation of the desulfurization unit, it is necessary to control the oxidation air volume required during the deoxidation process through a desulfurization fan. If there is a problem with the control system of the control unit, it will cause the air volume control of the desulfurization oxidation fan to be too large, resulting in an increase in the bubble content inside the desulfurization solution, a decrease in the density of the desulfurization solution, and a decrease in the desulfurization efficiency. In addition, when the air volume of the desulfurization oxidation fan is too large, the excess air will generate bubbles that overflow on the liquid surface of the desulfurization slurry. The overflowing bubbles will affect the judgment of the liquid level of the desulfurization slurry and is not conducive to the subsequent replenishment of the desulfurization slurry. Moreover, after breaking the larger bubbles on the surface of the desulfurization slurry, there will still be a large number of small bubbles floating on the surface of the desulfurization slurry, and at this time, it will still affect the judgment of the liquid level of the desulfurization slurry, thereby affecting the desulfurization effect.

[0005] Therefore, we propose an optimized control unit for the oxidation air volume of a desulfurization fan to facilitate solving the above-mentioned problems. Summary of the Invention

[0006] In view of the problems existing in the prior art, if there are problems with the control system of the control unit, the oxidation air volume is too large, which affects desulfurization. In addition, when the air volume is too large, the excess air will generate bubbles, which affects the addition of desulfurization slurry.

[0011] The linkage component includes a second floating ring. The second floating ring is fixedly connected to the bottom end of the first floating ring. One end of the second connecting pipe is fixedly connected with a third connecting pipe. One end of the third connecting pipe penetrates through the bottom wall of the first floating ring and extends into the second floating ring. A second one-way air outlet valve is installed inside the third connecting pipe;

[0012] Two groups of first magnets are symmetrically embedded and slidably connected to the inner wall of the second floating ring. The two first magnets in one group are fixedly connected together with a first extrusion rod. The top end of the first extrusion rod is rotatably connected with a rotating shaft. A second extrusion rod is fixedly connected to the side wall of the rotating shaft. A groove body is opened inside the second extrusion rod. The rotating shaft is located inside the groove body;

[0013] A torsion spring is fixedly connected to the inner top wall of the groove body. One end of the torsion spring is fixedly connected to the top end of the first extrusion rod. The torsion spring is sleeved on the outer side wall of the rotating shaft. Two groups of second piston plates are symmetrically and sealingly slidably connected inside the second floating ring. A second magnet is fixedly connected to the side wall of each second piston plate.

[0014] Further, the gas storage tank is fixedly connected to the side wall of the desulfurization tank. A first connecting pipe is fixedly connected to the bottom end of the gas storage tank. The bottom end of the first connecting pipe is fixedly connected to an air delivery pipe. One end of the air delivery pipe is fixedly connected through the top wall of the connection box. A one-way air delivery valve is installed inside the air delivery pipe.

[0015] Further, springs are symmetrically and fixedly connected to the inner top wall of the gas storage tank.

A second pressure relief valve is installed inside each second pressure relief hole.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] By setting up an auxiliary component, when the oxidation air volume is too large, the electric push rod is immediately activated. The movable end of the electric push rod starts to extend, driving the sealing plate to move downward synchronously. Since the sealing plate is in sealed sliding connection with the inner wall of the connection box, it can effectively change the oxygen flow rate passing through the connection box. The electric push rod drives the sealing plate to move downward until the oxidation air volume is adjusted to an appropriate size, at which point the electric push rod stops moving. By setting up a blowing component, when using the sealing plate to reduce the oxidation air volume passing through the connection box, the air flow rate around the sealing plate will increase. Since the oxidation air volume continuously enters, the one-way air supply valve is opened at this time. Under the action of the one-way air supply valve, the air flow accumulated around the sealing plate can only enter the inside of the gas storage tank along the air supply pipe to collect the excess gas. During this process, as oxygen continuously enters, the first piston plate compresses the spring and moves upward. By collecting oxygen, waste is avoided. When it is necessary to eliminate the bubbles on the liquid surface of the desulfurization slurry, the control valve and the first one-way air outlet valve are opened. At this time, under the elastic action of the spring, it drives the first piston plate to move downward, and in cooperation with the first one-way air outlet valve, the gas inside the gas storage tank can only be discharged into the first floating ring along the second connecting pipe and the air outlet pipe. As gas continuously enters the first floating ring, the excess gas will be ejected along the nozzle to form an air flow, blowing the bubbles on the liquid surface of the desulfurization slurry, effectively reducing the influence of bubbles on the judgment of the liquid level of the desulfurization slurry, facilitating the replenishment of the desulfurization slurry, and thus improving the desulfurization effect.

[0020] By setting up a linkage component, the first one-way air outlet valve is closed, and the second one-way air outlet valve and the first pressure relief valve are opened. At this time, the gas inside the gas storage tank will only be discharged into the second floating ring along the second connecting pipe and the third connecting pipe and is located between the two second piston plates. As gas continuously enters, the pressure between the two second piston plates increases, thereby pushing the two second piston plates and the first magnet to move. Since the adjacent surfaces of the first magnet and the second magnet have opposite magnetic polarities, under the action of the generated magnetic attraction force, it drives the first extrusion rod and the second extrusion rod to move along the rotating shaft, thereby squeezing the small bubbles on the liquid surface of the desulfurization slurry. As the first extrusion rod and the second extrusion rod continue to rotate, the small bubbles will gradually be broken, thereby removing the small bubbles, further reducing the influence of bubbles on the liquid level of the desulfurization slurry, facilitating the replenishment of the desulfurization slurry, and thus ensuring the desulfurization effect.

Specific implementation mode

[0036] The present invention will be further described below in conjunction with specific embodiments.

[0037] To solve the problem that during the operation of the desulfurization unit, it is necessary to control the oxidation air volume required during the deoxidation process through the desulfurization fan. If there is a problem with the control system of the unit, it will cause the air volume control of the desulfurization oxidation fan to be too large, resulting in an increase in the bubble content inside the desulfurization solution, a decrease in the density of the desulfurization solution, and a decrease in the desulfurization efficiency. As Figure 1 - Figure 7 shown:

[0038] A desulfurization fan oxidation air volume optimization control unit includes a support 1 and a desulfurization tank 2. The desulfurization tank 2 is installed on the support 1. The desulfurization tank 2 is filled with desulfurization slurry inside. A second air duct 31 is fixedly connected to the side wall of the desulfurization tank 2. A one-way valve 32 is installed inside the second air duct 31. One end of the second air duct 31 is provided with an auxiliary component 4. A first air duct 3 is installed on the side wall of the auxiliary component 4. The first air duct 3 is connected to the output end of the desulfurization fan to provide sufficient oxidation air volume during the desulfurization process. By setting the auxiliary component 4, when the oxidation air volume is too large, the electric push rod 44 is immediately started. The movable end of the electric push rod 44 starts to extend, driving the sealing plate 45 to move downward synchronously. Since the sealing plate 45 is in sealed sliding connection with the inner wall of the connection box 42, it can effectively change the oxygen flow passing through the connection box 42. The electric push rod 44 drives the sealing plate 45 to move downward until the oxidation air volume is adjusted to an appropriate size. At this time, the electric push rod 44 stops moving.

[0039] Inside the desulfurization tank 2, a blowing component 5 is installed. By setting up the blowing component 5, when using the sealing plate 45 to reduce the amount of oxygen passing through the connection box 42, the air flow around the sealing plate 45 will increase. Since the oxidation air volume continuously enters, at this time, open the one-way gas transmission valve 55. Under the action of the one-way gas transmission valve 55, the airflow accumulated around the sealing plate 45 can only enter the inside of the gas storage tank 51 along the gas transmission pipe 54 to collect the excess gas. During this process, as oxygen continuously enters, the first piston plate 53 compresses the spring 52 and moves upward. By collecting oxygen, waste is avoided. When it is necessary to eliminate the bubbles on the liquid surface of the desulfurization slurry, open the control valve 59 and the first one-way air outlet valve 511. At this time, under the elastic action of the spring 52, it will drive the first piston plate 53 to move downward. And with the cooperation of the first one-way air outlet valve 511, the gas inside the gas storage tank 51 can only be discharged into the first floating ring 512 along the second connecting pipe 58 and the air outlet pipe 510. As gas continuously enters the first floating ring 512, the excess gas will be ejected along the nozzle 513 to form an air flow, blowing the bubbles on the liquid surface of the desulfurization slurry, effectively reducing the influence of bubbles on the judgment of the liquid level of the desulfurization slurry, facilitating the replenishment of the desulfurization slurry, and thus improving the desulfurization effect.

[0040] At the bottom end of the blowing component 5, a linkage component 6 is installed. By setting up the linkage component 6, close the first one-way air outlet valve 511, and open the second one-way air outlet valve 63 and the first pressure relief valve 611. At this time, the gas inside the gas storage tank 51 will only be discharged into the second floating ring 61 along the second connecting pipe 58 and the third connecting pipe 62, and is located between the two second piston plates 68. As gas continuously enters, the pressure between the two second piston plates 68 increases, thereby pushing the two second piston plates 68 and the first magnet 67 to move. Since the adjacent surfaces of the first magnet 67 and the second magnet 69 have opposite magnetic polarities, under the action of the generated magnetic suction force, it drives the first extrusion rod 64 and the second extrusion rod 66 to move along the rotating shaft 65, thereby squeezing the small bubbles on the liquid surface of the desulfurization slurry. As the first extrusion rod 64 and the second extrusion rod 66 continue to rotate, the small bubbles will gradually be crushed, thereby removing the small bubbles, further reducing the influence of bubbles on the liquid level of the desulfurization slurry, being beneficial to the replenishment of the desulfurization slurry, and thus ensuring the desulfurization effect.

[0041] The auxiliary component 4 includes two fixing rods 41. Each fixing rod 41 is fixedly connected to the outer side wall of the desulfurization tank 2. One ends of the two fixing rods 41 are jointly fixedly connected with a connection box 42. The top end of the connection box 42 is provided with a rectangular hole 46. One side of the connection box 42 is fixedly connected through the second air duct 31, and the other side of the connection box 42 is fixedly connected through the first air duct 3.

[0042] At the top of the connection box 42, there is a support plate 43 fixedly connected. The support plate 43 is in an inverted U-shaped structure. At the top of the support plate 43, there is an electric push rod 44 fixedly connected. The movable end of the electric push rod 44 passes through the top wall of the support plate 43 and is fixedly connected with a sealing plate 45. The sealing plate 45 is slidably connected through the rectangular hole 46 and is slidably connected to the inner side wall of the connection box 42 in a sealed manner.

[0043] In this solution: When there is a problem with the control system of the control unit, it causes a large change in the air volume control of the desulfurization fan. If the oxidation air volume is too small, the main problem that occurs is that the oxygen content is insufficient, affecting the desulfurization effect. At this time, only sufficient oxygen needs to be supplemented through the remaining pipelines. When the oxidation air volume is too large, due to the problem with the control unit, it is difficult to adjust the air volume size, which has a greater impact. Therefore, when the oxidation air volume is too large, the electric push rod 44 is immediately started. The movable end of the electric push rod 44 starts to extend, driving the sealing plate 45 to move downward synchronously. Since the sealing plate 45 is slidably connected to the inner wall of the connection box 42 in a sealed manner, it can effectively change the oxygen flow passing through the inside of the connection box 42. The electric push rod 44 drives the sealing plate 45 to move downward until the oxidation air volume is adjusted to an appropriate size. At this time, the electric push rod 44 stops moving.

[0044] Subsequently, the staff repairs the control unit. After it is repaired, the electric push rod 44 is started to contract, driving the sealing plate 45 to move upward and reset, so as to facilitate subsequent continued use.

[0045] To solve the problem that when the air volume of the desulfurization oxidation fan is too large, the excess air will generate bubbles and overflow on the liquid surface of the desulfurization slurry. The overflowing bubbles will affect the judgment of the liquid level of the desulfurization slurry and are not conducive to the subsequent replenishment of the desulfurization slurry, as Figure 7 - Figure 9 shown:

[0046] The blowing assembly 5 includes an air storage tank 51. The air storage tank 51 is fixedly connected to the side wall of the desulfurization tank 2. At the bottom of the air storage tank 51, there is a first connecting pipe 57 fixedly connected in communication. At the bottom of the first connecting pipe 57, there is an air delivery pipe 54 fixedly connected in communication. One end of the air delivery pipe 54 is fixedly connected through the top wall of the connection box 42. A one-way air delivery valve 55 is installed inside the air delivery pipe 54.

[0047] On the inner top wall of the air storage tank 51, there are symmetrically fixed springs 52. One ends of the multiple springs 52 are jointly fixedly connected to a first piston plate 53. The first piston plate 53 is slidably connected to the inner wall of the air storage tank 51 in a sealed manner. The top of the air storage tank 51 is provided with multiple round holes 56. The side wall of the air storage tank 51 is fixedly connected in communication with a second connecting pipe 58.

[0048] A control valve 59 is installed inside the second connecting pipe 58. A first floating ring 512 is slidably connected inside the desulfurization tank 2. One end of the second connecting pipe 58 is fixedly connected through the top end of the first floating ring 512. Air outlet pipes 510 are symmetrically and fixedly communicated with the side wall of the second connecting pipe 58 located inside the first floating ring 512. A first one-way air outlet valve 511 is installed inside each air outlet pipe 510. A plurality of nozzles 513 are fixedly communicated with the inner side wall of the first floating ring 512 at equal angles.

[0049] In this solution: During the process of excessive oxidation air volume, due to more air flow entering the desulfurization slurry, a large number of bubbles will be generated inside the desulfurization slurry, and the bubbles will eventually overflow to the surface of the desulfurization slurry. When the desulfurization slurry is used for a period of time, the desulfurization slurry needs to be replenished. However, the existence of bubbles affects the addition of the desulfurization slurry. Too much will overflow, and too little will affect the desulfurization effect. Therefore, when the desulfurization slurry needs to be added, by using the sealing plate 45 to reduce the oxygen air volume passing through the inside of the connecting box 42, the air flow around the sealing plate 45 will become larger. Since the oxidation air volume continuously enters, at this time, the one-way gas transmission valve 55 is opened. Under the action of the one-way gas transmission valve 55, the air flow accumulated around the sealing plate 45 can only enter the inside of the gas storage tank 51 along the gas transmission pipe 54 to collect the excess gas. During this process, as oxygen continuously enters, the first piston plate 53 compresses the spring 52 and moves upward. By collecting oxygen, waste is avoided. When the bubbles on the surface of the desulfurization slurry need to be eliminated, the control valve 59 and the first one-way air outlet valve 511 are opened. At this time, under the elastic action of the spring 52, the first piston plate 53 will be driven to move downward. And with the cooperation of the first one-way air outlet valve 511, the gas inside the gas storage tank 51 can only be discharged into the inside of the first floating ring 512 along the second connecting pipe 58 and the air outlet pipes 510. As the gas continuously enters the inside of the first floating ring 512, the excess gas will be ejected along the nozzles 513, thus forming an air flow to blow the bubbles on the surface of the desulfurization slurry; By blowing the bubbles, the judgment of the liquid level of the desulfurization slurry by the bubbles is effectively reduced, so as to facilitate the replenishment of the desulfurization slurry, thereby improving the desulfurization effect.

[0050] In order to solve the problem that after the larger bubbles on the surface of the desulfurization slurry are broken, there will still be a large number of small bubbles floating on the surface of the desulfurization slurry. At this time, it will still affect the judgment of the liquid level of the desulfurization slurry, thereby affecting the desulfurization effect. As Figure 10 - Figure 14 shown:

[0051] The linkage assembly 6 includes a second floating ring 61. The second floating ring 61 is fixedly connected to the bottom end of the first floating ring 512. One end of the second connecting pipe 58 is fixedly connected with a third connecting pipe 62. One end of the third connecting pipe 62 penetrates the bottom wall of the first floating ring 512 and then extends into the inside of the second floating ring 61. A second one-way air outlet valve 63 is installed inside the third connecting pipe 62.

[0052] On the inner wall of the second floating ring 61, two groups of first magnets 67 are symmetrically and slidably connected in an embedded manner. Two first magnets 67 of one of the groups are fixedly connected to a first extrusion rod 64. The top end of the first extrusion rod 64 is rotatably connected to a rotating shaft 65. A second extrusion rod 66 is fixedly connected to the side wall of the rotating shaft 65. A groove 614 is formed inside the second extrusion rod 66, and the rotating shaft 65 is located inside the groove 614.

[0053] A torsion spring 615 is fixedly connected to the inner top wall of the groove 614. One end of the torsion spring 615 is fixedly connected to the top end of the first extrusion rod 64. The torsion spring 615 is sleeved on the outer side wall of the rotating shaft 65. Two groups of second piston plates 68 are symmetrically and sealingly slidably connected inside the second floating ring 61. A second magnet 69 is fixedly connected to the side wall of each second piston plate 68.

[0054] Each second magnet 69 is arranged corresponding to the adjacent first magnet 67. First pressure relief holes 610 are symmetrically formed on the inner wall of the second floating ring 61. A first pressure relief valve 611 is installed inside each first pressure relief hole 610. Second pressure relief holes 612 are symmetrically formed on the inner wall of the second floating ring 61. A second pressure relief valve 613 is installed inside each second pressure relief hole 612.

[0055] In this solution: Even if the bubbles are blown out by the air flow, there will still be many small bubbles on the surface of the desulfurization slurry. If not cleaned, it will still affect the addition of the desulfurization slurry and the desulfurization effect. At this time, close the first one-way air outlet valve 511, and open the second one-way air outlet valve 63 and the first pressure relief valve 611. At this time, the gas inside the gas storage tank 51 will only be discharged into the second floating ring 61 along the second connecting pipe 58 and the third connecting pipe 62, and is located between the two second piston plates 68. As the gas continuously enters, the pressure between the two second piston plates 68 increases, thereby pushing the two second piston plates 68 and the first magnet 67 to move. Since the adjacent surfaces of the first magnet 67 and the second magnet 69 have opposite magnetic polarities, under the action of the generated magnetic attraction force, the first extrusion rod 64 and the second extrusion rod 66 are driven to move along the rotating shaft 65, so as to squeeze the small bubbles on the liquid surface of the desulfurization slurry. As the first extrusion rod 64 and the second extrusion rod 66 continue to rotate, the small bubbles will be gradually broken, so as to remove the small bubbles, further reducing the influence of the bubbles on the liquid level of the desulfurization slurry, facilitating the replenishment of the desulfurization slurry, and thus ensuring the desulfurization effect; After the small bubbles are eliminated, open the second pressure relief valve 613. Under the action of the torsion spring 615, the first extrusion rod 64 and the second extrusion rod 66 are driven to rotate back to their original positions for subsequent continuous use;

[0056] Among them, the first floating ring 512 and the second floating ring 61 are both made of light materials and can effectively float on the surface of the desulfurization slurry. The second floating ring 61 is in contact with the liquid level of the desulfurization slurry, while the first floating ring 512 is not. As a result, both the first extrusion rod 64 and the second extrusion rod 66 are partially located inside the desulfurization slurry and the rest are above the desulfurization slurry. Therefore, during the movement, small bubbles can be effectively squeezed, causing the small bubbles to burst.
