Description

Technical Field

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

[0002] In addition to carbon dioxide, dust, sulfur, nitrogen oxides and carbon monoxide contained in the flue gas of coal-fired boilers are all air pollutants, which will cause damage to the human body, the environment and the ecology. Desulfurization control units are often used in the desulfurization process. The desulfurization control unit belongs to the ecological and environmental protection construction. The desulfurization control unit is mainly used for flue gas desulfurization treatment in coal-fired power plants and other facilities to reduce sulfur dioxide emissions. It is part of the ecological and environmental protection construction. Desulfurization slurry is often used in the desulfurization process. Desulfurization slurry is a slurry made by mixing desulfurization absorbents such as limestone with water. It is in slurry form and is used for wet flue gas.

[0003] Chinese patent CN221815754U proposes a desulfurization system limestone slurry efficient utilization system, including a desulfurization tower body, a slurry circulation pump, a support base and a top spray layer, a slurry pool is provided in the support base, the slurry circulation pump is provided with a liquid outlet pipe and a liquid extraction pipe extending to the bottom of 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 connected to the liquid extraction pipe, the slurry supply pipe is provided with a second control valve, the slurry supply pipeline is provided with a third control valve, and the liquid outlet pipe is provided with a plurality of spray pipes extending to the middle of the top spray layer. Compared with the prior art, the device has the advantages that the desulfurization system limestone slurry efficient utilization process can solve the problem of instantaneous excessive sulfur dioxide content in the clean flue gas when the unit load and the sulfur content of the coal fluctuate, which not only makes the fresh slurry efficiently and quickly utilized, but also reduces the calcium carbonate content in the gypsum.

[0004] At present, during the operation of the desulfurization unit, the desulfurization fan is needed to control the oxidation air volume required in the deoxygenation process. If there is a problem with the control system of the control unit, the air volume control of the desulfurization oxidation fan will be too large, resulting in an increase in the bubble content inside the desulfurization solution, resulting in 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, excess air will produce bubbles and overflow on the liquid surface of the desulfurization slurry. The overflowed bubbles will affect the liquid level judgment of the desulfurization slurry, which is not conducive to the subsequent replenishment of the desulfurization slurry. Moreover, 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, which will still affect the liquid level judgment of the desulfurization slurry and thus affect the desulfurization effect.

[0017] Compared with the prior art, the present invention has the following beneficial effects: By setting up an auxiliary component, when the oxidation air volume is too large, the electric push rod is immediately started, and the movable end of the electric push rod begins to extend, driving the sealing plate to move downward synchronously. Since the sealing plate is sealed and slidably connected to the inner wall of the connection box, the oxygen flow rate passing through the connection box can be effectively changed, and the sealing plate is driven downward by the electric push rod until the oxidation air volume is adjusted to an appropriate size. At this time, the electric push rod stops moving; by setting up an air blowing component, when the oxidation air volume passing through the connection box is reduced by using the sealing plate, the air flow around the sealing plate will become larger.

As the gas continuously enters the first floating ring, the excess gas will be sprayed out along the nozzle, thereby forming an airflow to blow the bubbles on the surface of the desulfurization slurry, effectively reducing the judgment of the liquid level of the desulfurization slurry by the bubbles, so as to facilitate the replenishment of the desulfurization slurry and improve the desulfurization effect; By setting 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.

As the gas continues to enter, 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 properties, the first extrusion rod and the second extrusion rod are driven to move along the rotating shaft under the action of the generated magnetic attraction, thereby squeezing small bubbles on the liquid surface of the desulfurization slurry.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with specific embodiments.

[0021] In order to solve the problem that during the operation of the desulfurization unit, the desulfurization fan is needed to control the oxidation air volume required in the deoxidation process. If there is a problem with the control system of the control unit, the air volume control of the desulfurization oxidation fan will be too large, resulting in an increase in the bubble content inside the desulfurization solution, resulting in a decrease in the density of the desulfurization solution and a decrease in the desulfurization efficiency. Figure 1 - Figure 7 As shown: A desulfurization fan oxidation air volume optimization control unit includes a bracket 1 and a desulfurization tank 2, the desulfurization tank 2 is installed on the bracket 1, the desulfurization tank 2 is filled with desulfurization slurry, the side wall of the desulfurization tank 2 is fixedly connected with a second air duct 31, a one-way valve 32 is installed in the second air duct 31, an auxiliary component 4 is installed at one end of the second air duct 31, and 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 for 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, and the active end of the electric push rod 44 begins to extend, driving the sealing plate 45 to move downward synchronously. Since the sealing plate 45 is sealed and slidably connected to the inner wall of the connecting box 42, the oxygen flow rate passing through the connecting box 42 can be effectively changed, and the sealing plate 45 is driven to move downward by the electric push rod 44 until the oxidation air volume is adjusted to an appropriate size, and the electric push rod 44 stops moving.

[0022] The desulfurization tank 2 is provided with a blowing assembly 5. By setting the blowing assembly 5 and reducing the oxygen air volume passing through the connection box 42 by using the sealing plate 45, the air volume around the sealing plate 45 will increase. As the oxidizing air volume continuously enters, the one-way gas supply valve 55 is opened at this time. Under the action of the one-way gas supply valve 55, the air flow accumulated around the sealing plate 45 can only enter the gas storage tank 51 along the gas supply pipe 54 to collect the excess gas. In this process, the first piston plate 53 compresses the spring 52 and moves upward as the oxygen continuously enters. By collecting the oxygen, waste is avoided. When it is necessary to remove the bubbles on the surface of the desulfurization slurry, When eliminating, 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, 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 first floating ring 512 along the second connecting pipe 58 and the air outlet pipe 510. As the gas continues to enter the first floating ring 512, the excess gas will be ejected along the nozzle 513, thereby forming an airflow to blow the bubbles on the surface of the desulfurization slurry, effectively reducing the judgment of the liquid level of the desulfurization slurry by the bubbles, so as to facilitate the replenishment of the desulfurization slurry and improve the desulfurization effect.

[0023] A linkage assembly 6 is installed at the bottom end of the blowing assembly 5. By setting the linkage assembly 6, the first one-way air outlet valve 511 is closed, and the second one-way air outlet valve 63 and the first pressure relief valve 611 are opened. 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 continues to enter, 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 properties, the first squeezing rod 64 and the second squeezing rod 66 are driven to move along the rotating shaft 65 under the action of the generated magnetic attraction force, thereby squeezing the small bubbles on the liquid surface of the desulfurization slurry. As the first squeezing rod 64 and the second squeezing rod 66 continue to rotate, the small bubbles will be gradually crushed, thereby taking out the small bubbles, further reducing the influence of the bubbles on the liquid level of the desulfurization slurry, which is beneficial to the replenishment of the desulfurization slurry, thereby ensuring the desulfurization effect.

[0024] The auxiliary component 4 includes two fixing rods 41, each of which is fixedly connected to the outer wall of the desulfurization tank 2. One end of the two fixing rods 41 is commonly fixedly connected to a connecting box 42. A rectangular hole 46 is provided on the top of the connecting box 42. One side of the connecting box 42 is penetrated and fixedly connected to the second air duct 31, and the other side of the connecting box 42 is penetrated and fixedly connected to the first air duct 3.

[0025] A support plate 43 is fixedly connected to the top of the connection box 42. The support plate 43 is an inverted U-shaped structure. An electric push rod 44 is fixedly connected to the top of the support plate 43. The movable end of the electric push rod 44 passes through the top wall of the support plate 43 and is fixedly connected to a sealing plate 45. The sealing plate 45 is slidably connected to the rectangular hole 46 and is sealed and slidably connected to the inner wall of the connection box 42.

[0026] In this scheme: when there is a problem with the control system of the control unit, the air volume control of the desulfurization fan will change greatly. If the oxidation air volume is too small, the main problem is that the oxygen content is insufficient, which affects the desulfurization effect. At this time, it is only necessary to supplement a sufficient amount of oxygen through the remaining pipelines. When the oxidation air volume is too large, it is difficult to regulate the air volume due to the problem with the control unit, which has a greater impact. Therefore, when the oxidation air volume is too large, the electric push rod 44 is immediately started, and the active end of the electric push rod 44 begins to extend, driving the sealing plate 45 to move downward synchronously. Since the sealing plate 45 is sealed and slidably connected to the inner wall of the connecting box 42, the oxygen flow rate passing through the inside of the connecting box 42 can be effectively changed, and the sealing plate 45 is driven to move downward by the electric push rod 44 until the oxidation air volume is adjusted to an appropriate size, and the electric push rod 44 stops moving at this time. Subsequently, the control unit is inspected and repaired by the staff, and after the repair, the electric push rod 44 is started to retract, driving the sealing plate 45 to move up and reset, so as to facilitate the subsequent continued use.

[0027] In order 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 surface of the desulfurization slurry. The overflowing bubbles will affect the liquid level judgment of the desulfurization slurry, which is not conducive to the subsequent replenishment of the desulfurization slurry. Figure 7 - Fig. 9 As shown: The blowing assembly 5 includes an air storage tank 51, which is fixedly connected to the side wall of the desulfurization tank 2. The bottom end of the air storage tank 51 is fixedly connected to a first connecting pipe 57, and the bottom end of the first connecting pipe 57 is fixedly connected to a gas supply pipe 54. One end of the gas supply pipe 54 passes through and is fixedly connected to the top wall of the connecting box 42, and a one-way gas supply valve 55 is installed inside the gas supply pipe 54.

[0028] Springs 52 are symmetrically fixedly connected to the inner top wall of the gas storage tank 51, one end of multiple springs 52 is commonly fixedly connected to a first piston plate 53, the first piston plate 53 is sealingly and slidably connected to the inner wall of the gas storage tank 51, a plurality of circular holes 56 are opened on the top of the gas storage tank 51, and a second connecting pipe 58 is fixedly connected to the side wall of the gas storage tank 51.

[0029] A control valve 59 is installed inside the second connecting pipe 58, and a first floating ring 512 is slidably connected inside the desulfurization tank 2. One end of the second connecting pipe 58 is fixedly connected to the top of the first floating ring 512. The side wall of the second connecting pipe 58 located inside the first floating ring 512 is symmetrically fixedly connected to the air outlet pipe 510, and a first one-way air outlet valve 511 is installed inside each air outlet pipe 510. A plurality of nozzles 513 are fixedly connected at equal angles to the inner wall of the first floating ring 512.

[0030] In this scheme: due to the large oxidation air volume, more airflow will enter the desulfurization slurry, causing more bubbles to be generated inside the desulfurization slurry, and the bubbles will eventually overflow to the surface of the desulfurization slurry. After the desulfurization slurry has been used for a period of time, it is necessary to replenish the desulfurization slurry, but the presence of bubbles affects the addition of the desulfurization slurry. Too much will overflow, and too little will affect the desulfurization effect. Therefore, when it is necessary to add desulfurization slurry, by using the sealing plate 45 to reduce the oxygen air volume passing through the connection box 42, the air flow around the sealing plate 45 will become larger. Due to the continuous entry of oxidation air volume, the one-way gas supply valve 55 is opened at this time. Under the action of the one-way gas supply valve 55, the airflow accumulated around the sealing plate 45 can only enter the gas storage tank 51 along the gas supply pipe 54 to collect excess gas. In this process, the first piston plate 53 is moved along As oxygen continuously enters, the spring 52 is compressed and moves upward, and oxygen is collected to avoid waste. When it is necessary to eliminate the bubbles on the surface of the desulfurization slurry, 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 is 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 first floating ring 512 along the second connecting pipe 58 and the air outlet pipe 510. As the gas continuously enters the first floating ring 512, the excess gas is ejected along the nozzle 513, thereby forming an airflow to blow up the bubbles on the surface of the desulfurization slurry; by blowing up 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.

[0031] 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, which will still affect the liquid level judgment of the desulfurization slurry and thus affect the desulfurization effect. Fig.10 - Fig.14 As shown: The linkage assembly 6 includes a second float ring 61, which is fixedly connected to the bottom end of the first float ring 512. One end of the second connecting tube 58 is fixedly connected to a third connecting tube 62. One end of the third connecting tube 62 passes through the bottom wall of the first float ring 512 and extends to the inside of the second float ring 61. A second one-way air outlet valve 63 is installed inside the third connecting tube 62.

[0032] Two groups of first magnets 67 are symmetrically embedded and slidably connected on the inner wall of the second floating ring 61, and the two first magnets 67 of one group are commonly fixedly connected to the first extrusion rod 64. The top of the first extrusion rod 64 is rotatably connected to the rotating shaft 65, and the side wall of the rotating shaft 65 is fixedly connected to the second extrusion rod 66. A groove body 614 is opened inside the second extrusion rod 66, and the rotating shaft 65 is located inside the groove body 614.

[0033] A torsion spring 615 is fixedly connected to the top wall of the groove body 614, one end of the torsion spring 615 is fixedly connected to the top of the first extrusion rod 64, and the torsion spring 615 is sleeved on the outer wall of the rotating shaft 65. Two sets of second piston plates 68 are symmetrically sealed and slidably connected inside the second floating ring 61, and each side wall of the second piston plate 68 is fixedly connected to a second magnet 69.

[0034] Each second magnet 69 is arranged corresponding to the adjacent first magnet 67, the inner wall of the second float ring 61 is symmetrically provided with first pressure relief holes 610, each first pressure relief hole 610 is installed with a first pressure relief valve 611, the inner wall of the second float ring 61 is symmetrically provided with second pressure relief holes 612, each second pressure relief hole 612 is installed with a second pressure relief valve 613.

[0035] In this solution: even if the bubbles are blown apart by air flow, there will still be many small bubbles on the surface of the desulfurization slurry. If they are not cleaned, it will still affect the addition of the desulfurization slurry and the desulfurization effect. At this time, the first one-way air outlet valve 511 is closed, and the second one-way air outlet valve 63 and the first pressure relief valve 611 are opened. 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 located between the two second piston plates 68. As the gas continues to enter, 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. Due to the first magnet 67 and the second magnet 69 The adjacent surfaces have opposite magnetic properties, so that under the action of the magnetic attraction force generated, 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 crushed, so that the small bubbles are taken out, further reducing the influence of the bubbles on the liquid level of the desulfurization slurry, which is beneficial to the replenishment of the desulfurization slurry, thereby ensuring the desulfurization effect; after the small bubbles are eliminated, the second pressure relief valve 613 is opened, and under the action of the torsion spring 615, the first extrusion rod 64 and the second extrusion rod 66 are driven to reset and rotate, so as to facilitate the subsequent continued use; The first float ring 512 and the second float ring 61 are both light in texture and can effectively float on the surface of the desulfurization slurry. The second float ring 61 is in contact with the liquid surface of the desulfurization slurry, and the first float ring 512 is not in contact with the liquid surface of the desulfurization slurry. Therefore, a part of the first squeezing rod 64 and the second squeezing rod 66 are both located in the desulfurization slurry, and the rest are located above the desulfurization slurry. Therefore, during the movement, small bubbles can be effectively squeezed and crushed.
