Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment engineering, in particular to a waste gas collecting device for waste gas treatment engineering. Background Art

[0002] Waste gas is one of the main sources of environmental pollution. Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes in enterprise plants. Industrial waste gas generally contains more chemical components that are harmful to the human body. Therefore, in order to protect the environment and health, waste gas needs to be treated. During the waste gas treatment process, it is necessary to use a waste gas collection device to guide the waste gas into the waste gas purification equipment.

[0003] In the Chinese utility model patent with the announcement number CN218741249U, a waste gas collection device for waste gas treatment engineering is disclosed. The waste gas collection device for waste gas treatment engineering is driven to move by the motor, and it does not need to be pushed manually, which reduces the labor intensity during movement. In addition, by introducing the gas to be purified into the inside of the purification liquid surface in the collection box, not only the waste gas can be fully contacted with the purification liquid, but also the purification liquid is prevented from moving to the outside.

[0004] By combining with the actual experience of waste gas collection and purification, it is found that the above technical solution still has some defects and shortcomings in the working process: the air intake hood in the reference document can only achieve height adjustment within a certain range through the electric push rod, which is not convenient for direct connection with the waste gas emission pipeline. It is easy for waste gas to escape and leak during waste gas collection, and the waste gas collection is insufficient. In addition, when the activated carbon filter plate with reduced purification effect needs to be replaced in the reference document, the waste gas emission needs to be stopped, which is complicated to operate and inconvenient. Therefore, it is urgent to improve the existing waste gas collection device and provide a waste gas collection device for waste gas treatment engineering. Utility Model Content

[0028] like Figure 1-6 As shown, the utility model of the waste gas collecting device for waste gas treatment engineering includes a mobile base 1, an exhaust pipe 2 is fixedly installed on the upper end of the mobile base 1, both left and right ends of the exhaust pipe 2 are fixedly connected with joints 6 through flanges, a positioning component 7 is provided on the outer side of the left end of the left joint 6, a mounting pipe 8 is inserted into the interior of the left joint 6, a closing component 9 is installed inside the mounting pipe 8, a fixing ring 12 is welded on the inner wall of the left joint 6, a T-shaped top column 13 is fixedly connected to the inner side of the fixing ring 12, an activated carbon filter plate 14 is movably sleeved on the outer side of the T-shaped top column 13, and the activated carbon filter plate 14 is located between the mounting pipe 8 and the fixing ring 12.

[0029] On the basis of the above structure, a support rod 3 is welded and fixed in the middle of the exhaust pipe 2, a motor 4 is fixedly installed on the middle right wall of the support rod 3, an exhaust fan 5 is fixedly connected to the output end of the motor 4, and the joint 6 is a funnel-shaped structure.

[0030] In this embodiment, the motor 4 is used to start and control the high-speed rotation of the exhaust fan 5, so that the exhaust gas can be collected through the exhaust effect and guided to the existing exhaust gas purification treatment equipment.

[0031] Based on the above structure, the positioning assembly 7 includes an adjusting ring 71, a spiral spring 711, an inclined groove 72 and an L-shaped rod 73. The adjusting ring 71 is installed on the outer side of the end of the joint 6 away from the exhaust pipe 2 through the spiral spring 711.

[0033] On the basis of the above structure, a hole-like structure adapted to the L-shaped rod 73 is opened on the outer wall of the mounting tube 8. The L-shaped rod 73 and the inclined groove 72 are arranged in a one-to-one correspondence. One end of the L-shaped rod 73 located outside the joint 6 is guided and slidably located on the inner side of the inclined groove 72.

[0034] In this embodiment, the hole-like structure corresponding to the outer wall of the mounting tube 8 and the L-shaped rod 73 is utilized to facilitate the engagement between the L-shaped rod 73 and the mounting tube 8, thereby facilitating the stable connection between the mounting tube 8 and the left joint 6.

[0035] Based on the above structure, one end of the mounting tube 8 away from the connector 6 is fixedly connected to an exhaust gas conveying hose 10, and the other end of the mounting tube 8 is annularly fixed with a plurality of limit strips 11 on its outer wall, and the inner wall of the connector 6 is provided with grooves corresponding one to one with the plurality of limit strips 11.

[0037] On the basis of the above structure, the closing component 9 includes an air leakage plate 91, a through groove 911, a cross bar 92, a sealing plate 93 and a support spring 94.
