Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and particularly to a high-temperature waste gas treatment device for acid-base waste gas mixed with water vapor. Background Art

[0002] When treating high-temperature waste gas, the current common process is to spray acid solution (dilute sulfuric acid) or alkali solution (sodium hydroxide solution) to absorb the waste gas. However, since the high temperature of the waste gas will affect the absorption effect, it is necessary to cool down the high-temperature waste gas first.

[0003] In the prior art, the liquid film cooling technology is often used. The absorbent (tap water) is introduced into the top of the treatment tower and evenly distributed on the cross-section of the tower through a distributor to form a continuous liquid film. The high-temperature waste gas is introduced from the bottom of the tower and passes upward through the liquid film in the tower. Due to the flow of the absorbent, there is a large contact area and a long contact time between the high-temperature waste gas and the absorbent, so that the temperature of the waste gas can be effectively reduced. The cooled waste gas then enters the subsequent spray tower for acid washing or alkali washing, and the absorption effect is better.

[0004] In the actual use process, it is found that the waste gas enters from the bottom of the tower and exits from the top of the tower, and its flow path in the tower remains unchanged, and it is impossible to adaptively adjust the flow path of the waste gas according to the waste gas temperature difference. For example, when the waste gas temperature is too high, if the flow path of the waste gas in the tower is short, it will lead to a limited contact time between the waste gas and the absorbent, making it difficult to achieve an effective cooling effect; on the contrary, when the waste gas temperature is low, if the flow path of the waste gas in the tower is long, although the waste gas can be fully cooled, the treatment efficiency of the waste gas is reduced. Therefore, we propose a high-temperature waste gas treatment device for acid-base waste gas mixed with water vapor to well solve the above drawbacks. Summary of the Invention

Detailed implementation manner

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1 to 8 , a high-temperature waste gas treatment device for acid-base waste gas mixed with water vapor, including a treatment tower 1 for cooling the high-temperature waste gas. This embodiment further includes: a hollow column 2, two first hollow plates 3, a first control member 5, two second hollow plates 6 and a second control member 13, which are used to solve the problem that the flow path of the waste gas in the treatment tower remains unchanged in the prior art and cannot adaptively adjust the flow path of the waste gas according to the temperature difference of the waste gas.

[0040] Specifically, the hollow column 2 is fixed in the treatment tower 1 and arranged along the axis of the treatment tower 1; the two first hollow plates 3 are respectively fixed on the front and rear sides of the hollow column 2, and the edge of the first hollow plate 3 away from the hollow column 2 is fixed to the inner wall of the treatment tower 1. A plurality of first ventilation openings 4 penetrate through each first hollow plate 3, and when the first ventilation openings 4 are opened, the waste gas can pass through normally. The first control member 5 is located within the two first hollow plates 3 and can move back and forth to open or close each first ventilation opening 4.

[0041] Two second hollow plates 6 are respectively fixed on the left and right sides of the hollow column 2, and the edges of the second hollow plates 6 far away from the hollow column 2 are fixed to the treatment tower 1. A number of second ventilation openings 7 penetrate through each second hollow plate 6. When the second ventilation openings 7 are open, the waste gas can pass through normally. Each first hollow plate 3 and each second hollow plate 6 cooperate to divide the inside of the treatment tower 1 into a first treatment chamber 8, a second treatment chamber 9, a third treatment chamber 10, and a fourth treatment chamber 11. Spraying and cooling assemblies 12 are installed in the upper spaces of the first treatment chamber 8, the second treatment chamber 9, the third treatment chamber 10, and the fourth treatment chamber 11 for spraying absorbent into each treatment chamber to cool the waste gas. The second control member 13 is located inside the two second hollow plates 6 and can move left and right to open or close each second ventilation opening 7.

[0042] It should be added that the first treatment chamber 8, the second treatment chamber 9, the third treatment chamber 10, and the fourth treatment chamber 11 are sequentially interconnected through external pipelines. Specifically, an intake pipe 14 communicating with the lower space of the first treatment chamber 8 is fixed on the treatment tower 1, and the external waste gas enters the first treatment chamber 8 from below through the intake pipe 14. An exhaust pipe 15 communicating with the upper space of the fourth treatment chamber 11 is fixed on the treatment tower 1, and the cooled waste gas is discharged from above through the exhaust pipe 15.

[0043] A first guide pipe 16 for communicating the upper space of the first treatment chamber 8 with the lower space of the second treatment chamber 9 is fixed on the treatment tower 1, and the waste gas in the first treatment chamber 8 can enter below the second treatment chamber 9 through the first guide pipe 16. A second guide pipe 17 for communicating the upper space of the second treatment chamber 9 with the lower space of the third treatment chamber 10 is fixed on the treatment tower 1, and the waste gas in the second treatment chamber 9 can enter below the third treatment chamber 10 through the second guide pipe 17. A third guide pipe 18 for communicating the upper space of the third treatment chamber 10 with the lower space of the fourth treatment chamber 11 is fixed on the treatment tower 1, and the waste gas in the third treatment chamber 10 can enter below the fourth treatment chamber 11 through the third guide pipe 18. Valves 19 are respectively installed on the first guide pipe 16, the second guide pipe 17, and the third guide pipe 18 for controlling the opening and closing of each guide pipe.

[0044] With the above structure, when cooling the waste gas, there are the following three states:

[0045] State 1: When treating high-temperature waste gas (waste gas temperature higher than 300 °C), use the first control member 5 to close the first ventilation opening 4 and use the second control member 13 to close the second ventilation opening 7. At this time, the first treatment chamber 8, the second treatment chamber 9, the third treatment chamber 10, and the fourth treatment chamber 11 are independent of each other, and the first treatment chamber 8, the second treatment chamber 9, the third treatment chamber 10, and the fourth treatment chamber 11 are sequentially connected in series through each guide pipe, and the waste gas flow path is the longest.

[0046] In this state, the external high-temperature waste gas first enters the first treatment chamber 8 through the intake pipe 14, then flows upward, and the corresponding spray cooling assembly 12 cools the high-temperature waste gas for the first time. The cooled waste gas enters the second treatment chamber 9 through the first gas guide pipe 16, then flows upward, and the corresponding spray cooling assembly 12 cools the high-temperature waste gas for the second time. The cooled waste gas enters the third treatment chamber 10 through the second gas guide pipe 17, then flows upward, and the corresponding spray cooling assembly 12 cools the high-temperature waste gas for the third time. The cooled waste gas enters the fourth treatment chamber 11 through the third gas guide pipe 18, then flows upward, and the corresponding spray cooling assembly 12 cools the high-temperature waste gas for the fourth time. Finally, the waste gas is discharged through the exhaust pipe 15. This long-process waste gas flow design, combined with four spray cooling operations, enables the waste gas to fully contact the absorbent, maximizing the absorption of heat in the waste gas and thus achieving efficient cooling.

[0047] State two: When treating medium-temperature waste gas (the waste gas temperature is between 150 - 300 °C), the first control member 5 moves backward to open the first air vent 4, and at the same time keeps the second air vent 7 closed. Then the valves 19 on the first gas guide pipe 16 and the third gas guide pipe 18 are closed. At this time, the first treatment chamber 8 and the second treatment chamber 9 communicate with each other through the first air vent 4, and the third treatment chamber 10 and the fourth treatment chamber 11 communicate with each other through the first air vent 4, and the waste gas flow path is moderate.

[0048] In this state, the waste gas first enters the cavity formed by the first treatment chamber 8 and the second treatment chamber 9 through the intake pipe 14, then flows upward, and the corresponding two spray cooling assemblies 12 perform the first spray cooling. The cooled waste gas enters the cavity formed by the third treatment chamber 10 and the fourth treatment chamber 11 through the second gas guide pipe 17, then flows upward, and the corresponding two spray cooling assemblies 12 perform the second spray cooling. Finally, the waste gas is discharged through the exhaust pipe 15. The flow path of this waste gas is relatively shortened compared to state one, and two spray cooling operations are performed simultaneously, which not only ensures sufficient heat exchange effect but also improves the waste gas treatment efficiency.

[0049] State three: When treating low-temperature waste gas (the waste gas temperature is below 150 °C), the first air vent 4 remains open, and at the same time the second control member 13 moves to the right to open the second air vent 7. Then the valves 19 on the first gas guide pipe 16, the second gas guide pipe 17, and the third gas guide pipe 18 are closed. At this time, the first treatment chamber 8, the second treatment chamber 9, the third treatment chamber 10, and the fourth treatment chamber 11 are all interconnected to form a cavity, and the waste gas flow path is the shortest.

[0050] In this state, the waste gas first enters the cavity through the intake pipe 14, then flows upward, and is spray-cooled once by the corresponding four spray cooling components 12. Finally, the waste gas is discharged through the exhaust pipe 15. The flow path of the waste gas in this process is the shortest, which fully improves the treatment efficiency of the waste gas.

[0051] The following is an introduction to the first control member 5:

[0052] The first control member 5 includes a first control board 501 movably arranged in each first hollow plate 3. A number of first connecting rods 502 are fixedly connected between the two first control boards 501. A first air guide port 503 adapted to the first air vent 4 is formed on each first control board 501. When the first air guide port 503 is completely staggered from the first air vent 4, the first air vent 4 is in a closed state. When the first air guide port 503 is aligned with the first air vent 4, the first air vent 4 is in an open state. In this embodiment, a first moving component 20 for moving the first control member 5 back and forth is installed on the side wall of the treatment tower 1. Specifically, the first moving component 20 includes an adjusting screw threadedly connected to the treatment tower 1, and one end of the adjusting screw is rotatably connected to the first control board 501. When the adjusting screw is rotated, the two first control boards 501 can be driven to move backward or forward synchronously.

[0053] The following is an introduction to the second control member 13:

[0054] The second control member 13 includes a second control board 131 movably arranged in each second hollow plate 6. A number of second connecting rods 132 are fixedly connected between the two second control boards 131. The second connecting rods 132 and the first connecting rods 502 are distributed vertically and horizontally in a staggered manner to ensure that the first control board 501 can move back and forth normally and the second control board 131 can move left and right normally without affecting each other. A second air guide port 133 adapted to the second air vent 7 is formed on each second control board 131. When the second air guide port 133 is aligned with the second air vent 7, the second air vent 7 is in an open state. When the second air guide port 133 is completely staggered from the second air vent 7, the second air vent 7 is in a closed state. In this embodiment, a second moving component 21 for moving the second control member 13 left and right is installed on the side wall of the treatment tower 1. The structure of the second moving component 21 is the same as that of the first moving component 20, and the second control board 131 is driven to move left and right by the same principle.

[0055] The following is an introduction to the spray cooling component 12:

[0056] The spray cooling component 12 includes a plurality of arc-shaped spray pipes 121 that are radially spaced apart along the processing tower 1. Both ends of each arc-shaped spray pipe 121 are respectively fixed to the adjacent first hollow plate 3 and second hollow plate 6, and a plurality of spray holes 122 are evenly distributed at the bottom of each arc-shaped spray pipe 121. A water delivery pipe is commonly connected and conducted on each arc-shaped spray pipe 121, and the water delivery pipe is conductively connected to an external water source. The external water source consists of a water storage tank and a water pump; that is, the spray cooling components 12 in each processing chamber are interconnected. When the valve on the water delivery pipe is opened, the water delivery pipe can supply water to each arc-shaped spray pipe 121 in each spray cooling component 12 synchronously. When the waste gas flows through the processing chamber from bottom to top, an absorbent can be sprayed onto the waste gas to reduce the temperature of the waste gas.

[0057] In some embodiments of the present application, when treating waste gases in three different states of high temperature, medium temperature, and low temperature, the flow path of the waste gas becomes shorter in sequence, but the corresponding number of spray times also decreases. To ensure the effect of spray cooling, the following design is specifically carried out:

[0058] The centers of each arc-shaped spray pipe 121 are all located on the axis of the hollow column 2. An arc-shaped adjusting pipe 22 is movably sleeved on each arc-shaped spray pipe 121. An adjusting hole 23 corresponding to the spray hole 122 is opened at the bottom of each arc-shaped adjusting pipe 22. A rotating component 24 is arranged in the processing tower 1 to synchronously rotate each arc-shaped adjusting pipe 22 along the axis of the hollow column 2.

[0059] When the first processing chamber 8, the second processing chamber 9, the third processing chamber 10, and the fourth processing chamber 11 are independent of each other, that is, when treating high-temperature waste gas, the spray holes 122 are completely open, and a maximum flow cross-section can be formed, promoting full contact between the absorbent and the high-temperature waste gas and achieving efficient cooling.

[0060] When the first processing chamber 8 is directly interconnected with the second processing chamber 9, and the third processing chamber 10 is directly interconnected with the fourth processing chamber 11, that is, when treating medium-temperature waste gas, the spray holes 122 are opened by one-half. At this time, the absorbent exchanges heat with the medium-temperature waste gas at a moderate flow rate and with a suitable atomization effect, ensuring the treatment effect and avoiding waste of resources.

[0061] When the first processing chamber 8, the second processing chamber 9, the third processing chamber 10, and the fourth processing chamber are directly interconnected, that is, when treating low-temperature waste gas, the spray holes 122 are opened by one-quarter, and the absorbent is ejected in the form of fine droplets at a faster speed, increasing the contact area with the low-temperature waste gas and meeting the cooling requirements.

[0062] With the above structure, during the process of cooling the waste gas:

[0063] State 1: When treating high-temperature waste gas, the flow path of the waste gas is the longest, and the number of times of spray cooling is four. During this process, the arc-shaped adjusting pipe 22 is in the initial state, and the adjusting hole 23 is completely aligned with the spray hole 122, so that the spray hole 122 is in a completely open state. In this case, a maximized flow cross-section can be formed, and spray cooling is carried out four times, so the heat in the high-temperature waste gas can be fully absorbed.

[0064] State 2: When treating medium-temperature waste gas, the flow path of the waste gas is moderate, and the number of times of spray cooling is two. During this process, the arc-shaped adjusting pipe 22 is driven by the rotating assembly 24 to rotate counterclockwise by a certain angle, so that the adjusting hole 23 is staggered from the spray hole 122 to a certain extent, so that the spray hole 122 is opened by one-half, and the spray speed is faster than that in State 1. At this time, the absorbent exchanges heat with the medium-temperature waste gas at a moderate flow rate and a suitable atomization effect, which not only ensures the treatment effect but also avoids waste of resources.

[0065] State 3: When treating low-temperature waste gas, the flow path of the waste gas is the shortest, and the number of times of spray cooling is one. During this process, the arc-shaped adjusting pipe 22 is driven by the rotating assembly 24 to continue rotating counterclockwise by a certain angle, so that the adjusting hole 23 is staggered from the spray hole 122 to the greatest extent, so that the spray hole 122 is opened by one-fourth, and the spray speed reaches the fastest. The smaller opening of the spray hole 122 combined with the fast spray speed can spray the absorbent into the waste gas in the form of high-frequency and small droplets, greatly increasing the contact surface area between the absorbent and the waste gas. Even if the number of spray times is small, heat exchange can be carried out quickly and fully, and the temperature of the waste gas can be quickly reduced.

[0066] The following introduces the rotating assembly 24:

[0067] The rotating assembly 24 includes a rotating shaft 241 rotatably connected to the hollow column 2. A rotating plug 242 that fits against the inner surface of the hollow column 2 is fixed to the upper end of the rotating shaft 241, and waste gas is not easily introduced into the hollow column 2. A linkage plate 243 fixed to each arc-shaped adjusting pipe 22 is fixed to the outer surface of the rotating plug 242. A relief opening 25 through which the linkage plate 243 passes is provided on the hollow column 2. When the rotating shaft 241 rotates, the rotating plug 242 can be driven to rotate synchronously, so as to drive each arc-shaped adjusting pipe 22 to rotate through the linkage plate 243 to adjust the alignment degree between the adjusting hole 23 and the spray hole 122.

[0068] In this embodiment, a gear 26 is fixed to the lower end of the rotating shaft 241. A first rack 27 that cooperates with the gear 26 is fixed to the first control member 5. The first rack 27 is actually fixed to the first connecting rod 502 in the first control member 5. A second rack 28 that cooperates with the gear 26 is fixed to the second control member 13. The second rack 28 is actually fixed to the second connecting rod 132 in the second control member 13.

[0069] When the first control member 5 moves backward, through the cooperation of the first rack 27 and the gear 26, the rotating shaft 241 is driven to rotate counterclockwise. When the second control member 13 moves to the right, through the cooperation of the second rack 28 and the gear 26, the rotating shaft 241 is driven to continue rotating counterclockwise, so that the alignment degree between the adjustment hole 23 and the spray hole 122 can be adjusted.

[0070] With the above structure, the adjustment of the opening size of the spray hole 122 is linked to the movement of the first control member 5 and the second control member 13. There is no need to separately design an additional driving mechanism to specifically adjust the opening size of the spray hole 122, which greatly simplifies the overall structure of the device, reduces the manufacturing cost, and improves the stability and reliability of the equipment operation.

[0071] It should be noted that in this article, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, article or device including the element.

[0072] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
