[0002] Metallurgical or chemical plants that use fossil fuels as energy usually emit a large amount of flue gas containing fly ash and harmful acidic gases such as SO2. In order to remove the atmospheric pollutant SO2 component in the flue gas, the most widely used desulfurization technology is spray desulfurization. The spray liquid is sent to the spray layer through a circulating pump. The spray layer consists of a spray main pipe, a spray branch pipe and a nozzle. The spray liquid is atomized by the nozzle to form small droplets, which come into countercurrent contact with the exhaust gas to wash and absorb the sulfur dioxide in the exhaust gas.

DETAILED DESCRIPTION

[0021] The core of the present invention is to provide a desulfurization device to adjust the waste gas flow rate according to the capacity of the waste gas in the desulfurization device.

[0022] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0023] like Figure 1-Figure 5 As shown, the desulfurization equipment disclosed in the embodiment of the present invention includes a shell 100, a spray mechanism 200 and a gas quantity control mechanism 300.

[0024] Among them, the shell 100 is provided with an exhaust gas inlet 102 and a gas outlet 104, and the exhaust gas to be treated can enter the shell 100 through the exhaust gas inlet 102 through the pipeline, and then be discharged from the shell 100 through the gas outlet 104. The exhaust gas inlet 102 can be set at the lower part of the shell 100, and the gas outlet 104 can be set at the top of the shell 100. The shell 100 is formed with at least two spray chambers between the exhaust gas inlet 102 and the gas outlet 104, and the spray chambers can be two or more than two. For ease of understanding, the following text takes two spray chambers as an example for introduction, and the two spray chambers are respectively a first spray chamber S and a second spray chamber M, and the first spray chamber S is located below the second spray chamber M.

[0025] The spray mechanism 200 includes a spray assembly 204, and the spray assembly 204 includes at least a spray pipe arranged in each spray chamber, and the spray pipe is used to spray spray liquid into the spray chamber. The spray pipe located in the first spray chamber S is the first spray pipe 204m, and the spray pipe located in the second spray chamber M is the second spray pipe 204l. The first spray pipe 204m is used to spray the spray liquid into the first spray chamber S to desulfurize the exhaust gas in the first spray chamber S; the second spray pipe 204l is used to spray the spray liquid into the second spray chamber M to desulfurize the exhaust gas in the second spray chamber M. In this embodiment, a plurality of spray chambers are arranged in the shell 100, and each spray chamber is provided with a spray pipe for spraying, so that the exhaust gas treated in the shell 100 can be divided into multiple sections for treatment, thereby improving the treatment efficiency.

[0026] The gas quantity control mechanism 300 includes at least a gas control component 301 arranged in each spray chamber, and in the same spray chamber, the gas control component 301 is located above the spray pipe to control the flow of the exhaust gas after spraying in the spray chamber to adjust the exhaust gas volume in each spray chamber.

[0027] The gas control assembly 301 includes a louver 301a, an elastic band 301b and a heat shrinkable part. The louver 301a is multiple and spaced and tilted. The distance between each louver 301a can adjust the exhaust gas flow through the gas control assembly 301. That is, the larger the distance between two adjacent louver 301a, the larger the exhaust gas flow through the gas control assembly 301, and the smaller the distance between two adjacent louver 301a, the smaller the exhaust gas flow through the gas control assembly 301. Therefore, the exhaust gas flow can be adjusted by adjusting the distance between the louver 301a. The louver 301a is tilted, so that the distance adjustment range between the louver 301a is larger. It can be understood by those skilled in the art that the larger the inclination angle of the louver plate 301a (relative to the inclination angle in the vertical direction), the more obvious the flow limiting effect on the exhaust gas, that is, the lower the flow rate; the smaller the inclination angle of the louver plate 301a (relative to the inclination angle in the vertical direction), the weaker the flow limiting effect on the exhaust gas, that is, the larger the flow rate. The upper part of each louver 301a is movably connected to the housing 100, so that the louver 301a can generate a certain amount of movement along the upper part. The lower part of the louver 301a is fixed to the elastic band 301b, and when the elastic band 301b is stretched, the angle of the louver 301a and the spacing of the lower part of the louver 301a will change.

[0028] There is at least one heat shrinkable component and it is disposed on the side wall of the housing 100. One end of the elastic band 301b is connected to the heat shrinkable component, and the other end is directly or indirectly connected to the side wall of the housing 100. That is, in this embodiment, at least one end of the elastic band 301b is connected to the side wall of the housing 100 through the heat shrinkable component. For example, one end of the elastic band 301b is connected to the side wall of the housing 100 through the heat shrinkable component, and the other end is directly connected to the side wall of the housing 100. Alternatively, both ends of the elastic band 301b may be connected to the side wall of the housing 100 through the heat shrinkable component.

[0029] When the temperature rises, the heat shrinkable part will shrink and deform, change its length, and thus generate tension on the elastic band 301b. Depending on the temperature, the shrinkage amount of the heat shrinkable part is different, and the tension generated is also different, and then the stretching length of the elastic band 301b can be changed according to the temperature. Since the temperature is related to the amount of exhaust gas, the stretching length of the elastic band 301b can be changed according to the amount of exhaust gas, and then the spacing of the lower part of the louver plate 301a can be changed to adjust the amount of exhaust gas passing.

[0030] The desulfurization equipment provided by the present invention has at least two spray chambers arranged in the shell 100, and each spray chamber can spray spray liquid separately. In addition, a gas control assembly 301 is arranged in each spray chamber, and the gas control assembly 301 includes a plurality of louvers 301a arranged at intervals and tilted, and the lower part of the louvers 301a is connected to the elastic band 301b, and the elastic band 301b is connected to the heat shrinkable part. The waste gas enters the shell 100 from the waste gas inlet 102 below, and first passes through the spray chamber at the bottom. When the waste gas in the spray chamber at the bottom is appropriate, it can be fully sprayed and washed by the spray pipe, and then slowly enters the upper spray chamber through the space between the plurality of louvers 301a for re-washing. Under the control of each gas control assembly 301, it can be fully washed and desulfurized. When there is a lot of waste gas in the spray chamber at the bottom, since the waste gas carries heat, the heat shrinkable part shrinks and pulls the elastic belt 301b, so that the elastic belt 301b is stretched, and the gaps between the louvers 301a fixed on the elastic belt 301b become larger, making it easier for the waste gas in the spray chamber at the bottom to enter the upper spray chamber for secondary washing.

[0031] The present invention can control the flow rate of the waste gas in the corresponding spray chamber according to the waste gas volume by setting a gas volume control mechanism, so that the flow rates of the waste gas in different spray chambers are different. Since the waste gas flows from the bottom to the top, the waste gas temperature at the bottom is higher, so the temperature of the spray chamber at the bottom is the highest, and the more waste gas volume, the higher the temperature. Based on the temperature of the spray chamber, the present invention can automatically adjust the spacing of the louver plates 301a, so that when there is a lot of waste gas in the spray chamber, more waste gas can be distributed into the next spray chamber for desulfurization treatment by increasing the spacing of the louver plates 301a of the spray chamber, so as to achieve the effect of reasonably distributing the flue gas volume in each spray chamber, and prevent too much waste gas from being retained in the spray chamber, which affects the treatment efficiency.

[0032] In a specific embodiment of the present invention, the gas control assembly 301 includes two heat shrinkable parts, which are symmetrically arranged on two opposite side walls of the housing 100. The two ends of the elastic band 301b are respectively connected to the two heat shrinkable parts. Such an arrangement makes it possible that when the amount of exhaust gas in the current spray chamber increases, the temperature of the spray chamber will rise, causing the heat shrinkable parts on the two side walls to shrink at the same time, generating a pulling force on the elastic band 301b in the direction of the two ends, causing the elastic band 301b to produce a larger deformation, and the louver 301a is adjusted to a larger spacing, thereby improving the adjustment efficiency.

[0033] Furthermore, a side wall groove 301d is provided on the side wall of the housing 100, and the heat shrinking member is a memory alloy spring 301f with one end fixed in the side wall groove 301d, and the other end of the memory alloy spring 301f is connected to a movable block 301e, and the movable block 301e is slidably matched with the side wall groove 301d. When the memory alloy spring 301f shrinks due to heat, it can pull the movable block 301e along the side wall groove 301d and move toward the inside of the side wall groove 301d; when the memory alloy spring 301f cools down and expands, it can push the movable block 301e along the side wall groove 301d and move toward the opening side of the side wall groove 301d. The movable block 301e can only reciprocate along the extension direction of the side wall groove 301d, and its moving direction is constrained by the side wall groove 301d, so as to prevent the movable block 301e from being segregated when moving, resulting in the inability to form a force on the elastic band 301b.

[0034] The movable block 301e is connected to the elastic band 301b through the connecting rope 301g. The movable block 301e is moved along the side wall groove 301d through the connecting rope 301g, acting on the elastic band 301b, thereby achieving the tightening and loosening of the elastic band 301b.

[0035] In a specific embodiment of the present invention, the louver plates 301a of the same gas control assembly 301 have the same inclination direction, and the louver plates 301a of two adjacent gas control assemblies 301 have opposite inclination directions, so that when the exhaust gas transitions from one spray chamber to another spray chamber, the flow direction needs to be changed to increase the movement path of the exhaust gas in the spray chamber and increase the contact time with the spray liquid. For example, if the louver 301a of the first spray chamber S is inclined to the left, then the louver 301a of the second spray chamber M is inclined to the right, and the exhaust gas of the first spray chamber S is discharged from the first spray chamber S in a flow direction to the left, and enters the second spray chamber M, forming an exhaust gas flow inclined to the left. After the exhaust gas flow hits the side wall of the shell 100, it changes direction and flows upward along the side wall. When it flows out of the second spray chamber M, it forms an airflow to the right. In this way, under the action of the opposite inclination directions of the louver 301a of the two spray chambers, the exhaust gas flow can flow from bottom to top along the shell 100 in a left-right folding manner, thereby increasing the path of the exhaust gas flow and improving the spraying time.

[0036] In a specific embodiment of the present invention, the upper part of the louver 301a is movably connected to the housing 100 through the support rod 301c. The upper part of the louver 301a is provided with a support hole 301a1, and the support rod 301c passes through the support hole 301a1 of each louver 301a, and the two ends are respectively fixed on the inner walls of the housing 100 on both sides. Each louver 301a has a support hole 301a1 at the same position on the upper part, and the support rod 301c passes through the support hole 301a1 of each louver 301a, and ensures that the distance between each louver 301a at the support rod 301c is the same. Then, by using the opening position of the side wall groove 301d, the position of the memory alloy spring 301f and the movable block 301e in the side wall groove 301d, and the length of the connecting rope 301g, each louver 301a is arranged tilted in the same direction.

[0037] The diameter of the support hole 301a1 should be larger than the diameter of the support rod 301c, so that when the elastic band 301b is stretched and relaxed, that is, when the distance between the end of the louver 301a connected to the elastic band 301b is increased and decreased, the louver 301a can be deflected at a certain angle along the support rod 301c to adjust the resistance of the exhaust gas flowing through here.

[0038] In a specific embodiment of the present invention, the spray mechanism 200 includes a water pump 202 . Specifically, a water tank 201 may be provided at the bottom of one side of the shell 100 , and the water pump 202 may be provided in the water tank 201 . The water pump 202 may be supported by the water tank 201 .

[0039] The water pumping end of the water pump 202 is connected to the water pumping pipe 202a, which passes through the side wall of the shell 100 and enters the inside of the shell 100, and is used to extract the spray liquid deposited at the bottom of the shell 100 after spraying. The water discharge end of the water pump 202 is connected to the drain pipe 203, and the drain pipe 203 is connected to each spray pipe. Specifically, the drain pipe 203 is connected to the first branch pipe 203a and the second branch pipe 203b, and the first branch pipe 203a and the second branch pipe 203b pass through the side wall of the shell 100 and enter the first spray chamber S and the second spray chamber M respectively. The first spray pipe 204m and the second spray pipe 204l are connected to the first branch pipe 203a and the second branch pipe 203b respectively through the first hose 204o and the second hose 204n.

[0040] In a specific embodiment of the present invention, the desulfurization equipment may further include a filter screen 101 and a demister 103. The filter screen 101 is disposed in the housing 100 and is located below the lowest spray chamber (i.e., the first spray chamber S). The water pumping pipe 202a is connected to the bottom of the filter screen 101. The spray liquid is filtered by the filter screen 101 and then falls to the bottom of the housing 100 for collection, and is pumped away through the water pumping pipe 202a for recycling.

[0041] The demister 103 is disposed in the shell 100 and is located between the highest spray chamber and the gas outlet 104. After the exhaust gas is sprayed and washed by the first spray chamber S and the second spray chamber M, it is processed by the demister 103 and then discharged from the gas outlet 104 at the top of the shell 100.

[0042] Since the exhaust gas carries its own heat, when the amount of exhaust gas inside the shell 100 is small and the temperature is not high, the exhaust gas will be blocked by the multiple louvers 301a in the gas control component 301 in the first spray chamber S because the multiple louvers 301a are tilted in the same direction, which slows down the exhaust gas from the first spray chamber S to the second spray chamber M and then from the second spray chamber M through the demister 103. More residence time allows the exhaust gas to be washed more thoroughly.

[0043] When the amount of exhaust gas inside the shell 100 increases, the temperature inside the shell 100 rises, and the memory alloy spring 301f in the side wall groove 301d corresponding to the first spray chamber S shrinks due to heat, pulling the movable block 301e to move into the side wall groove 301d. The movable block 301e pulls the multiple louvers 301a through the connecting rope 301g to reduce the inclination angle, and the gaps between the multiple louvers 301a become larger, so that more exhaust gas can pass through the multiple louvers 301a into the second spray chamber M for spray washing. The temperature of the exhaust gas has dropped after the spray washing in the first spray chamber S, so the memory alloy spring 301f in the side wall groove 301d corresponding to the second spray chamber M shrinks less due to heat, and the exhaust gas is blocked by multiple louvers 301a, and the speed of passing through the gaps between the multiple louvers 301a slows down. It stays in the second spray chamber M for a longer time for spray washing and desulfurization, and then passes through the multiple louvers 301a above the second spray chamber M, and is finally discharged from the gas outlet 104 at the top of the shell 100 after being processed by the demister 103.

[0044] In a specific embodiment of the present invention, the spray assembly 204 also includes a mobile driving device for driving each spray pipe to reciprocate in the spray chamber, and the mobile driving device includes a rotating motor 204g, a connecting rod structure, a gear 204k, a first tooth plate 204a, a second tooth plate 204d and a slider 204e.

[0045] One end of the connecting rod structure is fixed to the rotating shaft 204h of the rotating motor 204g, and the other end of the connecting rod structure is hinged to the gear shaft of the gear 204k. Specifically, the connecting rod structure includes a first rotating plate 204i and a second rotating plate 204j, one end of the first rotating plate 204i is fixed to the rotating shaft 204h, and the other end is hinged to one end of the second rotating plate 204j, and the other end of the second rotating plate 204j is hinged to the gear shaft of the gear 204k.

[0046] When the rotating motor 204g outputs power, it can drive the first rotating plate 204i to make a circular motion through its rotating shaft 204h, and at the same time drive the second rotating plate 204j to make a reciprocating motion in space, and drive the gear 204k to roll back and forth on the first tooth plate 204a.

[0047] The first tooth plate 204a and the second tooth plate 204d are arranged in parallel, and the second tooth plate 204d can be arranged above the first tooth plate 204a. The first tooth plate 204a and the second tooth plate 204d are both meshed with the gear 204k. The first tooth plate 204a is fixed to the inner wall of the housing 100, so the first tooth plate 204a is arranged below to improve the support effect of the gear 204k. The second tooth plate 204d is slidably matched with the inner wall of the housing 100. When the gear 204k rolls back and forth on the first tooth plate 204a, it will drive the second tooth plate 204d to slide relative to the inner wall of the housing 100. The power for the sliding of the second tooth plate 204d comes from two points. One is that during the movement of the gear 204k relative to the first tooth plate 204a, the second tooth plate 204d is pushed, so that the second tooth plate 204d moves with the gear 204k; the other is that during the rotation of the gear 204k around its own axis, the second tooth plate 204d can be moved relative to the gear 204k through the meshing of the gear rack, so the moving distance of the second tooth plate 204d is greater than the moving distance of the gear 204k. By using the mobile drive device disclosed in this embodiment, the second tooth plate 204d can be moved a larger distance in the narrow space of the shell 100 by utilizing the limited moving distance of the gear 204k.

[0048] The slider 204e is slidably matched with the inner wall of the housing 100 and connected to the second tooth plate 204d. One of the spray pipes is fixed on the second tooth plate 204d, and the other spray pipes are fixed on the slider 204e one by one. When the second tooth plate 204d moves, the slider 204e can be driven to move synchronously, thereby driving the corresponding spray pipes to move back and forth synchronously.

[0049] A first guide portion is provided on the inner wall of the housing 100, and a second guide portion that is slidably matched with the corresponding first guide portion is provided on the second tooth plate 204d and the slider 204e. For example, the first guide portion may be a slide groove (wherein the slide groove corresponding to the second tooth plate 204d is the first slide groove 204b, and the slide groove corresponding to the slider 204e is the second slide groove 204c), and the second guide portion is a slide rail; accordingly, the first guide portion may be a slide rail, and the second guide portion may be a slide groove.

[0050] To summarize, the exhaust gas inlet pipe is connected to an external vacuum pump, and the vacuum pump draws the sulfur-containing exhaust gas through the exhaust gas inlet pipe and the exhaust gas inlet 102 into the first spray chamber S of the shell 100, and the water pump 202 and the rotating motor 204g are turned on. The water pump 202 draws the spray liquid at the bottom of the shell 100 to the drain pipe 203, and the first branch pipe 203a and the second branch pipe 203b provide spray liquid to the first spray pipe 204m and the second spray pipe 204l through the first hose 204o and the second hose 204n.

[0051] The rotating motor 204g drives the rotating shaft 204h to rotate, and the rotating shaft 204h drives the first rotating plate 204i to rotate, and the other end of the first rotating plate 204i is rotatably connected to one end of the second rotating plate 204j, and the other end of the second rotating plate 204j is rotatably connected to the gear shaft of the gear 204k, so the gear 204k can continuously reciprocate under the push-pull action of the second rotating plate 204j. Since the gear 204k is respectively meshed with the second tooth plate 204d and the first tooth plate 204a, the gear 204k can drive the second tooth plate 204d to reciprocate when it reciprocates, and the top end of the second tooth plate 204d is connected to the bottom end of the slider 204e through the connecting plate 204f, so when the second tooth plate 204d reciprocates, it can also drive the slider 204e to reciprocate through the connecting plate 204f. The first spray pipe 204m and the second spray pipe 204l connected to the second tooth plate 204d and the slider 204e respectively move accordingly, expanding the area of ​​the water mist sprayed by the first spray pipe 204m and the second spray pipe 204l, so that the exhaust gas in the shell 100 can be washed more fully.
