Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization, in particular to a novel central exhaust gas treatment device. Background Art

[0002] Desulfurization refers to the process of removing sulfur-containing substances. It is commonly used in industrial fields such as coal combustion, oil processing, and steel smelting to reduce or prevent sulfur dioxide and other sulfides from polluting the environment and human body.

[0003] At present, the existing waste gas treatment device (such as patent number: CN213101537U) discloses a waste gas desulfurization device, which stores absorption liquid at the bottom of the device body and stirs the absorption liquid with a stirring shaft to improve the desulfurization effect of the absorption liquid and avoid precipitation. The first baffle can move the waste gas entering the device body to the absorption liquid, and the upper part uses a spraying method to improve the mixing effect of the absorption liquid and the waste gas. The air guide pipe can re-introduce the sprayed gas into the absorption liquid for re-mixing to improve the overall desulfurization effect.

[0004] However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: after the waste gas is processed, it continues to flow through the discharge pipe at the top. The content of the waste gas treated in each time period is different. When the discharge speed is the same, some untreated waste gas will flow out directly through the pipe, affecting the environment. Utility Model Content

When the discharge speed is the same, some untreated exhaust gas will directly flow out through the pipe, affecting the environment.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A novel central exhaust gas treatment device comprises a tower body, wherein two second fixing rings are fixedly installed inside the tower body, a same connecting plate is fixedly installed inside the two second fixing rings, at least two spray heads are fixedly installed outside the connecting plate, a motor box is fixedly installed on the top end of one of the second fixing rings, and a first fixing ring is fixedly installed inside the tower body.

[0011] (III) Beneficial effects

[0020] The embodiment of the present application provides a new type of central exhaust gas treatment device, which effectively solves the problem that after the exhaust gas is processed, it continues to circulate through the discharge pipe at the top. The content of the exhaust gas treated in each time period is different.

The slide plate moves on the surface of the driving rod, and the two ends of the slide plate apply the same force to the push rod, and the push rod deflects upward.

The deflection angle of the closing plate can be adjusted to adjust the space inside the first fixed ring, and the circulation speed can be flexibly adjusted according to the desulfurization progress of the exhaust gas.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that after the waste gas is processed, it continues to flow through the discharge pipe at the top. The waste gas content treated in each time period is different. When the discharge speed is the same, some untreated waste gas will flow directly through the pipe, affecting the environment. The overall idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a novel central exhaust gas treatment device, which includes a tower body 1, wherein two second fixing rings 13 are fixedly installed inside the tower body 1, the same connecting plate 15 is fixedly installed on the inner sides of the two second fixing rings 13, at least two spray heads 16 are fixedly installed on the outer sides of the connecting plate 15, a motor box 19 is fixedly installed on the top of one of the second fixing rings 13, and a desulfurizer is transported to the inside of the motor box 19, the inside of the motor box 19 is connected to the connecting plate 15 through a pipeline, the desulfurizer enters the inside of the connecting plate 15, and is sprayed to the inside of the tower body 1 through the spray heads 16 on both sides, a first fixing ring 11 is fixedly installed inside the tower body 1 above the second fixing ring 13, and both ends of the spray head 16 are designed with inclined surfaces and are symmetrically installed with each other.

[0024] Two closing plates 12 are rotatably installed inside the first fixed ring 11, and a fixed block 17 is fixedly installed at the bottom end of each closing plate 12. A push rod 18 is rotatably installed at the bottom end of each fixed block 17. The push rod 18 is obliquely installed at the end of the fixed block 17. A driving rod 22 is rotatably installed at the top of the motor box 19, and a slide plate 23 is rotatably installed on the surface of each driving rod 22. Both ends of the slide plate 23 are rotatably connected to the end of the push rod 18. A filter screen 14 is fixedly installed inside each second fixed ring 13, and a connecting pipe 21 is fixedly installed on both side ends of the motor box 19. The end of the connecting pipe 21 is connected to the inner side of the tower body 1, so that the two ends of the slide plate 23 apply the same force to the push rod 18, and the push rod 18 deflects upward. At the same time, the top end of the push rod 18 applies a force to the closing plate 12, so that the closing plate 12 rotates inside the first fixed ring 11 to adjust the deflection angle of the closing plate 12.

[0025] Working principle:

[0026] The first step is to introduce the exhaust gas into the tower body 1 during use. The exhaust gas accumulates inside the tower body 1. The inner side of the tower body 1 is connected to the connecting pipe 21, and the desulfurizer is transported to the inside of the motor box 19. The inside of the motor box 19 is connected to the connecting plate 15 through a pipeline. The desulfurizer enters the inside of the connecting plate 15 and is sprayed to the inside of the tower body 1 through the spray heads 16 on both sides. The desulfurizer is atomized and contacts the exhaust gas. At the same time, the exhaust gas flows upward inside the tower body 1, passes through two second fixing rings 13, and a filter screen 14 is installed inside the second fixing ring 13. The filter screen 14 intercepts particulate matter in the exhaust gas and filters impurities in the exhaust gas. At the same time, the two ends of the spray head 16 are inclined, and the desulfurizer is sprayed. The two ends of the spray head 16 respectively flush the second fixing ring 13 to prevent the accumulation of exhaust gas impurities inside the second fixing ring 13, which causes the tower body 1 to be blocked. After being filtered by the filter screen 14 and treated with the desulfurizer, the exhaust gas continues to flow upward and leaves the inside of the tower body 1 through the first fixing ring 11 at the top of the tower body 1.

[0027] The second step, when in use, the driving rod 22 can be driven to rotate by the motor box 19, the surface of the driving rod 22 and the slide plate 23 are fitted with each other, and the threaded groove on the surface of the driving rod 22 exerts a force on the slide plate 23, so that the slide plate 23 moves on the surface of the driving rod 22, and the two ends of the slide plate 23 exert the same force on the push rod 18, and the push rod 18 deflects upward. At the same time, the top of the push rod 18 exerts a force on the closing plate 12, so that the closing plate 12 rotates inside the first fixed ring 11. By adjusting the deflection angle of the closing plate 12, the space inside the first fixed ring 11 can be adjusted, and the circulation speed can be flexibly adjusted according to the desulfurization progress of the exhaust gas.

[0028] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
