Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment, specifically to a waste gas transmission device for waste gas treatment. Background Technology

[0002] Waste gas refers to a mixture of gases that contain pollutants or may be harmful to the environment or human health and are emitted into the atmosphere during human production, daily life activities or other natural processes.

[0003] In order to safely and efficiently transport the waste gas generated in production or daily life to the treatment equipment, it is often necessary to use transmission pipes to transport the waste gas. However, waste gas often carries impurities, so during the transmission process, impurities are easy to stick to the inner wall of the transmission pipe. Moreover, because the pipe is often long and thin, it is difficult to clean the impurities, which can easily affect the service life.

[0004] Therefore, it is necessary to invent an exhaust gas transmission device for exhaust gas treatment to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a waste gas transmission device for waste gas treatment. When wastewater at different temperatures comes into contact with the air bladder, the air bladder deforms to different degrees due to the different expansion degrees of the gas inside. As a result, impurities are detached from the inner wall of the pipe due to the deformation, which can solve the problem of impurities sticking to the inner wall of the pipe and being difficult to clean in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste gas transmission device for waste gas treatment, comprising... The transmission pipe body is installed at the exhaust gas outlet, and the inner wall of the transmission pipe body is provided with an installation groove. An anti-adhesion mechanism is installed inside the transmission tube body. The anti-adhesion mechanism includes an air bladder. The outer surface of the air bladder is fixedly connected to the inner wall of the mounting groove. The air bladder is annular in shape and has a cavity in the middle. The cavity is filled with nitrogen gas. The thickness of the left and right sides of the air bladder is greater than that of the middle part.

[0007] Preferably, the mounting groove is composed of multiple concentric annular grooves with arc-shaped cross-sections, and the depth of the grooves increases from left to right.

[0008] Preferably, a straight pipe is fixedly connected to the outer wall of the transmission pipe body, the number of the straight pipes is set to multiple, and there is a preset distance between each pair of adjacent straight pipes. A limiting ring is fixedly connected to the outer circumferential surface of the transmission pipe body between each pair of adjacent straight pipes, and the number of the limiting rings is set to multiple.

[0009] Preferably, there is a preset distance between each pair of adjacent limiting rings and the distances are consistent, and a shock-absorbing ring is fixedly connected between each pair of adjacent limiting rings.

[0010] Preferably, the left end of the leftmost straight tube is in the same plane as the left end of the transmission tube body, and the right end of the rightmost straight tube is in the same plane as the right end of the transmission tube body.

[0011] Preferably, a flange is fixedly connected to the outer circumference of the leftmost straight pipe near the left side, and a flange is fixedly connected to the outer circumference of the rightmost straight pipe near the right side.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention, through the design of the airbag, allows the side of the airbag closest to the axis of the transmission tube to expand to different degrees depending on the temperature of the gas inside the transmission tube. This causes a deviation in the curvature of the outer surface of the side of the airbag closest to the axis of the transmission tube. As the airbag deforms, the contact surface between the impurities adhering to its surface and the airbag changes, making them easier to detach. This achieves the effect of preventing impurities from adhering and being difficult to clean. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1 - Figure 4 The exhaust gas transmission device for exhaust gas treatment shown includes: a transmission pipe body 1 installed at the exhaust gas outlet and an anti-sticking mechanism 2 disposed inside the transmission pipe body 1. The inner wall of the transmission tube body 1 is provided with an installation groove 11, which is composed of multiple concentric circular grooves with arc-shaped cross-sections, and the depth of the grooves increases from left to right. like Figure 2 - Figure 4 As shown, the anti-adhesion mechanism 2 includes an airbag 21. The outer surface of the airbag 21 is fixedly connected to the inner wall of the mounting groove 11. The airbag 21 is annular in shape, and there are multiple airbags 21. The airbag 21 has a cavity 211 in the middle, which is filled with nitrogen. The size of the cavity 211 in the multiple airbags 21 increases from left to right. When the airbag 21 is at room temperature, the area near the middle of the single annular groove of the mounting groove 11 is concave. The thickness of the left and right sides of the airbag 21 is greater than that of the middle. By setting the thickness, it is ensured that when the temperature of the space where the airbag 21 is located changes, the expansion change of the left and right sides is less than that of the middle. Since the temperature of the input gas will gradually approach room temperature during the input process, by increasing the thickness in sequence, it is ensured that when the temperature of the exhaust gas changes during the movement of the transmission pipe body 1, the deformation difference of the airbag 21 caused by the temperature difference is small.

[0018] like Figure 1 - Figure 4 As shown, a straight pipe 31 is fixedly connected to the outer wall of the transmission pipe body 1. The straight pipe 31 is made of rigid material and can be fixed externally by clamps, fasteners, etc. during use. The number of straight pipes 31 is set to multiple, and there is a preset distance between each pair of adjacent straight pipes 31. The left end of the leftmost straight pipe 31 is on the same plane as the left end of the transmission pipe body 1, and the right end of the rightmost straight pipe 31 is on the same plane as the right end of the transmission pipe body 1. Limiting rings 32 are fixedly connected to the outer circumferential surface of the transmission pipe body 1 between each pair of adjacent straight pipes 31. The number of limiting rings 32 is set to multiple, and there is a preset distance between each pair of adjacent limiting rings 32. The distance between each pair of adjacent limiting rings 32 is less than the thickness of a single limiting ring 32. The limiting rings 32 are made of rigid material. A shock-absorbing ring 33 is fixedly connected between each pair of adjacent limiting rings 32. The shock-absorbing ring 33 is made of flexible material, and the outer diameter of the shock-absorbing ring 33 is larger than the outer diameter of the limiting ring 32.

[0019] like Figure 1As shown, a flange is fixedly connected to the outer circumference of the leftmost straight pipe 31 near the left side, and a flange is fixedly connected to the outer circumference of the rightmost straight pipe 31 near the right side. The flanges ensure that the equipment can be more easily connected to the exhaust pipe of the exhaust gas discharge equipment and the exhaust gas input end of the exhaust gas treatment equipment.

[0020] The working principle of this utility model is as follows: Since the temperature of the waste gas to be transported varies each time, and the temperature inside the transport pipe 1 also differs between when the waste gas is being transported and when it is not, the volume of nitrogen inside the gas bag 21 changes with the surrounding temperature. Therefore, when the temperature of the transported waste gas is high, the gas bag 21 expands more, and when the temperature of the waste gas is low, the gas bag 21 expands less. When no waste gas is being transported, the gas bag 21 returns to its original shape as the internal temperature of the transport pipe 1 gradually approaches room temperature. Thus, when waste gas is being transported, even if impurities carried by the waste gas adhere to the surface of the gas bag 21, gaps will appear at the adhesion points due to the dynamic changes of the gas bag 21, making it easier for the impurities to detach from the surface of the gas bag 21. Furthermore, during the gas transport process, the gas also generates a pushing force on the impurities, making it even easier for loosely adhered impurities to detach from the surface of the gas bag 21. Therefore, when maintenance is needed, the operator only needs to invert the equipment to allow the impurities to fall off.

[0021] During equipment use, if it is necessary to change the direction of conveying, the operator rotates the area where the limiting ring 32 of the equipment is located. Since the limiting ring 32 is rigid, the area inside the limiting ring 32 of the transmission pipe body 1 cannot deform. Only the area between each pair of limiting rings 32 can deform. When deformation occurs in this area, the position of the limiting ring 32 also changes. When the outer surfaces of two adjacent limiting rings 32 come into contact with each other, the limiting rings 32 cannot continue to deform due to mutual contact. Therefore, there is a threshold for the amount of deformation of the transmission pipe body 1, thereby ensuring that the transmission pipe body 1 will not have a bending area in the middle due to large deformation, which would affect the normal transmission of exhaust gas.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
