Description

Technical Field

[0001] The invention relates to the field of thermal power generation cycle, and in particular to a thermal power generation cycle system. Background Art

[0002] In the flue gas purification and desulfurization treatment system of existing thermal power generation equipment, untreated flue gas is usually transported to a desulfurization tower for treatment, and then the treated flue gas is discharged to the outside air through a chimney. In this process, heat exchange is usually performed between the untreated flue gas and the treated flue gas to reduce the temperature of the untreated flue gas, so as to avoid the untreated flue gas from having too high a temperature when entering the desulfurization tower, thereby increasing the difficulty of desulfurization of the untreated flue gas by the desulfurization tower. At the same time, the temperature of the treated flue gas is increased to avoid a large temperature difference between the treated flue gas and the outside air, which results in the generation of white smoke when the treated flue gas contacts the outside air. However, since the temperature of the treated flue gas remains unchanged after heat exchange, and the temperature of the outside air is different in each season, after the heat exchange, the temperature of the outside air may be higher than that of the treated flue gas, or lower than that of the treated flue gas, that is, there will still be a large temperature difference between the treated flue gas and the outside air, resulting in the generation of white smoke when the treated flue gas comes into contact with the outside air.

DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0018] Example 1 A thermal power generation cycle system, such as Figure 1-4 As shown, it includes a base frame 1, a delivery pipe 2, a long barrel 3, an air inlet pipe 4 and an air outlet pipe 5; the base frame 1 is fixedly connected with a delivery pipe 2 for conveying untreated flue gas; the delivery pipe 2 is fixedly connected with the long barrel 3; the upper left part of the long barrel 3 is connected and fixedly connected with the air inlet pipe 4; the upper right part of the long barrel 3 is connected and fixedly connected with the air outlet pipe 5; It also includes a U-shaped channel plate 6, a fan-shaped plate 7, a U-shaped adjustment plate 8 and an electric push rod 9; the conveying pipe 2 is fixedly connected to four U-shaped channel plates 6; four fan-shaped plates 7 are fixedly connected to the left and right sides of the conveying pipe 2, and each fan-shaped plate 7 is fixedly connected to the corresponding U-shaped channel plate 6, and each fan-shaped plate 7 is fixedly connected to the long barrel 3; each U-shaped channel plate 6 is slidably connected to a U-shaped adjustment plate 8, and each U-shaped adjustment plate 8 is slidably connected to the long barrel 3; four electric push rods 9 are fixedly connected to the left and right sides of the long barrel 3, and the telescopic part of each electric push rod 9 is fixedly connected to the corresponding U-shaped adjustment plate 8.

[0019] It also includes an elastic air guide cloth 10 ; the left side of the U-shaped adjustment plate 8 is fixedly connected with an elastic air guide cloth 10 for allowing the treated flue gas to better enter the channel of the U-shaped channel plate 6 .

[0020] The specific operation of the above-mentioned embodiment 1 is as follows: first, the right end of the delivery pipe 2 is connected to the pipe through which the untreated flue gas flows, the left end of the delivery pipe 2 is connected to the pipe flowing into the desulfurization tower, the air inlet pipe 4 is connected to the pipe through which the treated flue gas flows after being treated by the desulfurization tower, and the air outlet pipe 5 is connected to the chimney, so as to install the device on the flue gas purification and desulfurization treatment system of the thermal power generation equipment.

[0021] according to Figure 1 and Figure 2 As shown, when the flue gas purification and desulfurization treatment system of the thermal power generation equipment is in use, the pipeline through which the untreated flue gas flows will transport the untreated flue gas to the conveying pipe 2, and then the untreated flue gas will flow into the desulfurization tower through the conveying pipe 2 for desulfurization treatment, and the treated flue gas after desulfurization treatment will flow into the left space between the conveying pipe 2 and the long barrel 3 through the air inlet pipe 4. At this time, the treated flue gas is blocked by the fan plate 7, and the treated flue gas will flow into the right space between the conveying pipe 2 and the long barrel 3 through the U-shaped channel plate 6, and then the treated flue gas will flow into the chimney through the air outlet pipe 5, and finally discharged to the outside air through the chimney. In this process, since the untreated flue gas is a high-temperature gas and the treated flue gas is much lower than the temperature of the untreated flue gas, the untreated flue gas flowing in the conveying pipe 2 and the untreated flue gas flowing in the U-shaped channel plate 6 will exchange heat to reduce the temperature of the untreated flue gas, and at the same time, increase the temperature of the treated flue gas to achieve heat recycling.

[0022] Taking into account that the temperature of the treated flue gas remains unchanged after heat exchange, while the temperature of the outside air is different in each season and the temperature difference is large, there will still be a large temperature difference between the treated flue gas and the outside air after heat exchange, resulting in the generation of white smoke when the treated flue gas comes into contact with the outside air.

[0023] Therefore, according to the temperature of the outside air, the telescopic part of the electric push rod 9 can be controlled to adjust the channel size of the U-shaped channel plate 6 through the U-shaped adjustment plate 8 to adjust the temperature of the heat exchange of the treated flue gas. Specifically, when the temperature of the outside air is higher than that of the treated flue gas, the telescopic part of the electric push rod 9 is controlled to push the U-shaped adjustment plate 8 to move away from the conveying pipe 2 to expand the channel of the U-shaped channel plate 6. At this time, since the total amount of treated flue gas does not change, and the channel of the U-shaped channel plate 6 is expanded, the speed of the treated flue gas flowing through the U-shaped channel plate 6 will be slowed down, and the time for the treated flue gas to flow through the U-shaped channel plate 6 will be prolonged, that is, the heat exchange time between the treated flue gas and the untreated flue gas will be prolonged, so that the temperature of the discharged treated flue gas can rise to a higher level, that is, it is closer to the outside air. When the outside air is lower than the temperature of the treated flue gas, the telescopic portion of the electric push rod 9 is controlled to push the U-shaped adjustment plate 8 to move towards the conveying pipe 2 to reduce the channel of the U-shaped channel plate 6. At this time, since the total amount of treated flue gas does not change, and the channel of the U-shaped channel plate 6 is reduced, the speed of the treated flue gas flowing through the U-shaped channel plate 6 will be accelerated, and the time for the treated flue gas to flow through the U-shaped channel plate 6 will be shortened, that is, the heat exchange time between the treated flue gas and the untreated flue gas will be shortened, so that the temperature rise of the treated flue gas is small, that is, it reaches a level that is not much different from the outside temperature, so as to prevent the outside air from being much lower than the temperature of the treated flue gas and causing white smoke.

[0024] In this way, the channel size of the U-shaped channel plate 6 is adjusted by cooperating with the U-shaped adjustment plate 8 through the electric push rod 9 to adjust the length of time that the treated flue gas flows through the U-shaped channel plate 6, so as to adjust the temperature of the heat exchange of the treated flue gas, so as to avoid the problem that when the temperature of the treated flue gas after heat exchange remains unchanged while the outside air temperature changes, the difference between the treated flue gas emission temperature and the outside air temperature is large, and a large amount of white smoke will still appear.

[0025] Furthermore, when the treated flue gas flows into the left space between the conveying pipe 2 and the long barrel 3 through the air inlet pipe 4, the treated flue gas is guided by the elastic air guide cloth 10 so that the treated flue gas can better enter the channel of the U-shaped channel plate 6.

[0026] Example 2 On the basis of Example 1, Figure 1-7 and Figure 10-11As shown, it also includes a pushing component and a mixing component; each U-shaped adjustment plate 8 is connected to a pushing component for pushing the treated flue gas to move; each U-shaped channel plate 6 is connected to a mixing component for mixing the treated flue gas; the pushing component includes a push plate 101 and a power unit 1; the U-shaped adjustment plate 8 is rotatably connected to four push plates 101; the U-shaped adjustment plate 8 is connected to a power unit 1 for driving the push plate 101 and the parts connected thereto to rotate, and the power unit 1 is connected to all the push plates 101.

[0027] The pushing component 1 also includes a push plate 102 and an electric push rod 103; each push plate 101 is slidably connected to a push plate 102; each push plate 101 is bolted to an electric push rod 103, and the telescopic part of each electric push rod 103 is fixedly connected to the corresponding push plate 102, and the electric push rod 103 is used to control the push plate 102 to extend and retract from the push plate 101.

[0028] The lower surfaces of the push plate 1 101 and the push plate 2 102 are both provided with arc-shaped recesses, which are used to enable the push plate 1 101 and the push plate 2 102 to better push the treated flue gas to move.

[0029] The power unit 1 includes a mounting frame 111, a pneumatic push rod 112, a rack 113 and a gear 114; the U-shaped adjustment plate 8 is slidably connected to the mounting frame 111; the U-shaped adjustment plate 8 is bolted to the pneumatic push rod 112, and the telescopic part of the pneumatic push rod 112 is fixedly connected to the mounting frame 111; the mounting frame 111 is fixedly connected to four racks 113; each push plate 101 is fixedly connected to a gear 114, and each gear 114 is meshed with the corresponding rack 113.

[0030] The mixing assembly includes a motor 201 and mixing blades 202; the U-shaped channel plate 6 is bolted with four motors 201; the U-shaped channel plate 6 is rotatably connected with four mixing blades 202, and each mixing blade 202 is fixedly connected to the output shaft of the corresponding motor 201.

[0031] It also includes an elastic cloth 211; each push plate 102 is fixedly connected to an elastic cloth 211, and each elastic cloth 211 is fixedly connected to the corresponding U-shaped adjustment plate 8, and the elastic cloth 211 is made of high temperature resistant material.

[0032] The specific operation of the above-mentioned embodiment 2 is as follows: Considering that when the treated flue gas flows through the U-shaped channel plate 6, since the heat exchange process between the treated flue gas and the untreated flue gas is in indirect contact, the efficiency of the heat exchange is not high. In the heat exchange process, the treated flue gas flowing through the U-shaped channel plate 6 away from the conveying pipe 2 is not convenient for fully absorbing heat, that is, the treated flue gas away from the conveying pipe 2 is easily lower than the temperature of the outside air. Therefore, when the treated flue gas away from the conveying pipe 2 is discharged to the outside air, it is still easy to produce white smoke.

[0033] Therefore, when the treated flue gas flows through the U-shaped channel plate 6, based on the view from the front to the back, the telescopic part of the pneumatic push rod 112 is first controlled to drive the push plate 101 and its connected parts to rotate clockwise and counterclockwise through the mounting frame 111, the rack 113 and the gear 114 in sequence. In this process, when the push plate 101 and its connected parts rotate clockwise, Fig.11 As shown, the push plate 1 101 and the push plate 2 102 cooperate to push the treated flue gas away from the delivery pipe 2 to flow toward the delivery pipe 2. At the same time, the output shaft of the control motor 201 drives the mixing blades 202 to rotate clockwise and counterclockwise continuously, so that the mixing blades 202 mix the treated flue gas away from the delivery pipe 2 and the treated flue gas close to the delivery pipe 2, so that the temperature of the treated flue gas flowing through the U-shaped channel plate 6 is basically the same, thereby avoiding the problem that the treated flue gas away from the delivery pipe 2 flowing through the U-shaped channel plate 6 is not convenient to fully absorb heat, that is, the treated flue gas away from the delivery pipe 2 is easy to be lower than the temperature of the outside air.

[0034] Furthermore, considering that when the push plate 101 and the push plate 2 102 rotate counterclockwise, the rotating push plate 101 and the push plate 2 102 will move the treated flue gas to flow toward the outlet pipe 5, that is, under this movement, the speed of the treated flue gas flowing through the U-shaped channel plate 6 will be accelerated, which is likely to affect the heat exchange time between the treated flue gas and the untreated flue gas; Therefore, by adding an elastic cloth 211 to the push plate 102, when the push plates 101 and 102 rotate counterclockwise, the push plates 101 and 102 are restricted by the elastic cloth 211 and cannot move most of the treated flue gas. This can avoid the problem that when the push plates 101 and 102 rotate counterclockwise, the rotating push plates 101 and 102 will move most of the treated flue gas to flow toward the outlet pipe 5.

[0035] It should be noted that when the channel of the U-shaped channel plate 6 is expanded or reduced, the telescopic part of the electric push rod 2 103 can be manually controlled to push the push plate 2 102 to extend or retract in the push plate 1 101 according to the expansion or reduction of the channel of the U-shaped channel plate 6, so that the push plates 1 101 and 102 can adapt to the expanded or reduced channel of the U-shaped channel plate 6, so that the push plates 1 101 and 102 can cooperate with each other to normally push the treated flue gas away from the delivery pipe 2 to flow toward the delivery pipe 2.

[0036] Example 3 On the basis of Example 2, Figure 1-4 and Figure 8-11 As shown, it also includes a pushing component 2; each U-shaped channel plate 6 is connected to a pushing component 2 for making the treated flue gas convect with each other; the pushing component 2 includes a push plate 3 301 and a power unit 2; the U-shaped channel plate 6 is rotatably connected to four push plates 3 301; the U-shaped channel plate 6 is connected to a power unit 2 for driving the push plate 3 301 and the parts connected thereto to rotate, and the power unit 2 is connected to all the push plates 3 301.

[0037] Pushing assembly 2 also includes a push plate 4 302 and an electric push rod 3 303; each push plate 301 is slidably connected to a push plate 4 302; each push plate 301 is fixedly connected to an electric push rod 3 303, and the telescopic part of each electric push rod 3 303 is fixedly connected to the corresponding push plate 4 302, and the electric push rod 3 303 is used to control the push plate 4 302 to extend and retract from the push plate 3 301.

[0038] The upper surfaces of push plate three 301 and push plate four 302 are both provided with arc-shaped recesses, which are used to enable push plate one 101 and push plate two 102 to better push the treated flue gas to move.

[0039] The power unit 2 includes a mounting frame 2 401, a pneumatic push rod 2 402, a rack 2 403 and a gear 2 404; the U-shaped channel plate 6 is slidably connected to the mounting frame 2 401; the U-shaped channel plate 6 is fixedly connected to the pneumatic push rod 2 402, and the telescopic part of the pneumatic push rod 2 402 is fixedly connected to the mounting frame 2 401; the mounting frame 2 401 is fixedly connected to four racks 2 403; each push plate 301 is fixedly connected to a gear 2 404, and each gear 2 404 is meshed with the corresponding rack 2 403.

[0040] It also includes an elastic cloth 2 411; each push plate 4 302 is fixedly connected to an elastic cloth 2 411, and each elastic cloth 2 411 is fixedly connected to the conveying pipe 2, and the elastic cloth 2 411 is made of high temperature resistant material.

[0041] The specific operation of the above-mentioned embodiment 3 is as follows: Considering that the push plate 1 101 and the push plate 2 102 cooperate to push the treated flue gas away from the conveying pipe 2, according to Fig.11 It can be seen that the space where the treated flue gas flows through the U-shaped channel plate 6 will be blocked by the push plate 1 101 and the push plate 2 102 and will be intermittently reduced, and the speed at which the treated flue gas flows through the U-shaped channel plate 6 will be intermittently accelerated, making it difficult for the mixing blades 202 to completely mix the treated flue gas away from the conveying pipe 2 and the treated flue gas close to the conveying pipe 2.

[0042] Therefore, based on the view from the front to the back, when the push plate 1 101 and the parts connected thereto rotate clockwise, the telescopic portion of the control pneumatic push rod 2 402 drives the push plate 3 301 and the parts connected thereto to rotate counterclockwise through the mounting frame 2 401, the rack 2 403 and the gear 2 404 in sequence, and the push plate 1 101 and the parts connected thereto rotate synchronously with the push plate 3 301 and the parts connected thereto. In this process, the push plate 3 301 cooperates with the push plate 4 302 to push the treated flue gas close to the delivery pipe 2 to move away from the delivery pipe 2 direction, so that the treated flue gas away from the delivery pipe 2 and the treated flue gas close to the delivery pipe 2 convect with each other, so as to slow down the speed of the treated flue gas flowing through the U-shaped channel plate 6, so as to prevent the space when the treated flue gas flows through the U-shaped channel plate 6 from being blocked by the push plate 1 101 and the push plate 2 102. The speed of the treated flue gas flowing through the U-shaped channel plate 6 will be intermittently reduced, and the speed of the treated flue gas flowing through the U-shaped channel plate 6 will be intermittently accelerated, resulting in the problem that it is difficult for the mixing blades 202 to completely mix the treated flue gas away from the delivery pipe 2 and the treated flue gas close to the delivery pipe 2.

[0043] It should be noted that when the channel of the U-shaped channel plate 6 is expanded or reduced, the telescopic part of the electric push rod three 303 can be manually controlled to push the push plate four 302 to extend or retract in the push plate three 301 according to the expansion or reduction of the channel of the U-shaped channel plate 6, so that the push plates three 301 and four 302 are adapted to the expanded or reduced channel of the U-shaped channel plate 6, and the treated flue gas away from the conveying pipe 2 pushed by the push plates one 101 and two 102 and the treated flue gas close to the conveying pipe 2 pushed by the push plates three 301 and four 302 can be convected normally.

[0044] Furthermore, since the elastic cloth 2 411 has the same function as the elastic cloth 1 211, the elastic cloth 2 411 can also avoid the problem that when the push plates 3 301 and 4 302 rotate clockwise, the rotating push plates 3 301 and 4 302 will move most of the treated flue gas to flow toward the direction close to the exhaust pipe 5.

[0045] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
