Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment towers, and more specifically, to a waste gas conveying device for a waste gas treatment tower. Background Art

[0002] During the production processes of chemical products and pharmaceutical manufacturing, due to reasons such as raw material volatilization or chemical reactions, a large amount of waste gas will inevitably be generated. To protect the environment, industrial waste gas is not allowed to be directly discharged. It needs to be conveyed to the waste gas treatment tower through the waste gas conveying device of the waste gas treatment tower and can be discharged only after being treated. In the existing waste gas conveying device of the waste gas treatment tower, the air outlet end of the waste gas conveying pipe is connected to the air inlet of the fan, and the air outlet of the fan is communicated with the waste gas treatment tower through a pipeline. In the waste gas conveying device with the above structure, the waste gas enters the fan through the waste gas conveying pipe and then is sent to the waste gas treatment tower by the fan. Since the waste gas is highly corrosive, it causes great damage to the fan, resulting in a greatly shortened service life of the fan and increasing the operating cost of the enterprise. Therefore, in order to protect the fan, the conveying method has evolved to the blowing type. The fan blows air into the pipeline, and using the principle that the pressure is small when the flow rate is large, the waste gas squeezed into the waste gas pipeline by the high-speed flowing air is sucked into the conveying pipeline to protect the fan.

[0003] For example, the patent with the application number 2023212985812 discloses a waste gas conveying device for a waste gas treatment tower, which has better conveying effect. It includes a waste gas treatment tower main body. The right end of the waste gas treatment tower main body is provided with a waste gas conveying pipe. The right end of the waste gas conveying pipe is provided in a through shape. The middle part of the right end of the waste gas conveying pipe is provided with a drainage fan, and the drainage fan is matched with the right end of the conveying pipe. The bottom of the waste gas conveying pipe is provided with a waste gas discharge pipe, and the air outlet end of the waste gas discharge pipe penetrates into the waste gas conveying pipe.

[0004] However, in the prior art, the fan is directly connected to the waste gas pipeline, and no isolation operation is performed on the pipeline during the shutdown process. The flow direction of the waste gas is uncertain, which leads to the easy direct leakage of the waste gas to the outside after shutdown, causing pollution, resulting in incomplete waste gas treatment in the waste gas treatment tower, affecting the use effect of the waste gas treatment tower, and having low structural safety.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] See also Figures 1 to 4 In the utility model, a waste gas conveying device of a waste gas treatment tower includes a waste gas treatment tower main body 1, a conduit 2 is fixedly connected to the right side of the waste gas treatment tower main body 1, the other end of the conduit 2 is fixedly connected to a horn guide cavity 3, a powerful fan 4 is fixedly installed inside the right end of the horn guide cavity 3, an air guide box 5 is installed inside the horn guide cavity 3, a cavity 6 is opened inside the air guide box 5, and evenly distributed air holes 7 are opened on both sides of the air guide box 5, an elastic sealing member 8 is installed on the air guide box 5, and an exhaust gas inlet pipe 9 is fixedly installed at the bottom of the conduit 2.

[0023] After the exhaust fan 4 is shut down, the exhaust gas in the exhaust pipe 9 is sucked into the exhaust pipe 2 and transported to the exhaust gas treatment tower body 1 for treatment. When the exhaust fan 4 is shut down, the elastic sealing member 8 is reset to block the vent 7 on the right side, so that the interior of the exhaust pipe 2 is sealed and isolated from the outside to prevent the exhaust gas from leaking out. The device has the advantages of safely sealing and isolating the internal exhaust gas after shutdown, avoiding leakage, and being safer and more environmentally friendly. It solves the problem of direct connection between the fan and the exhaust pipe in the prior art, which makes it easy for the exhaust gas to leak directly to the outside after shutdown, causing pollution, and having low structural safety.

[0024] See also Figure 1 and Figure 2, wherein: A section of the conduit 2 is provided with a downward-complete arc-shaped pipe 21. An inclined coarse filter plate 22 is fixedly connected inside the arc-shaped pipe 21, and a discharge pipe 23 is fixedly connected to the bottom of the arc-shaped pipe 21.

[0025] In the present utility model, the coarse filter plate 22 inside the arc-shaped pipe 21 is used to roughly filter large particles in the waste gas, facilitating subsequent cleaning processes, and the discharge pipe 23 is used to conveniently discharge solid waste.

[0026] Please refer to Figure 1 and Figure 2 , wherein: The front view section of the waste gas inlet pipe 9 is inclined, and the inclined direction at the top of the waste gas inlet pipe 9 is the same as the air flow direction.

[0027] In the present utility model, the inclined waste gas inlet pipe 9 makes the waste gas be inhaled more smoothly, reducing eddy currents and making the air flow more smooth.

[0028] Please refer to Figure 3 and Figure 4 , wherein: The elastic seal 8 includes a wind resistance block 81, a sliding rod 82, a sealing disc 83 and a spring 84. One side of the wind resistance block 81 is fixedly connected to the sliding rod 82, the other end of the wind resistance block 81 is fixedly connected to the sliding rod 82, the other end of the sliding rod 82 is inserted into the inside of the air guide box 5 and fixedly connected to the sealing disc 83. The sealing disc 83 is located inside the cavity 6. The spring 84 is sleeved outside the sliding rod 82. One end of the spring 84 is fixedly connected to the right side of the air guide box 5, and the other end of the spring 84 is fixedly connected to the wind resistance block 81.

[0029] In the present utility model, when the wind resistance block 81 is pushed by the air flow to drive the sliding rod 82 to move and compress the spring 84, the sealing disc 83 moves inside the cavity 6 to separate its right side from the ventilation hole 7, enabling the air flow to smoothly pass through the air guide box 5 and enter the inside of the conduit 2. When the machine stops, under the reaction force of the spring 84, the sealing disc 83 is reset to seal the ventilation hole 7 on the right side, achieving the effect of preventing waste gas leakage.

[0030] Please refer to Figure 3 , wherein: A sealing block 831 that is snap-fitted with the ventilation hole 7 is fixedly connected to the right side of the sealing disc 83.

[0031] In the present utility model, the sealing block 831 makes the sealing effect of the sealing disc 83 on the ventilation hole 7 better.

[0032] Please refer to Figure 3 , wherein: A limit stop block 61 is installed inside the cavity 6, and the limit stop block 61 is located on the left side of the sealing disc 83.

[0033] In the present utility model, the movement position of the closing disc 83 is restricted by the limit stop block 61 to prevent excessive movement from obstructing the ventilation hole 7 on the left side.

[0034] The above is only a preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, making equivalent substitutions or changes according to the technical solution of the present utility model and its improved concept, shall be covered by the protection scope of the present utility model.
