Description

Technical Field

[0001] The invention relates to the technical field of environmentally friendly exhaust gas, and in particular to an environmentally friendly universal exhaust device. Background Art

[0002] At present, with the continuous development of science and technology, the continuous increase of laboratory instruments, the waste gas generated after laboratory experiments will also increase. Laboratory waste gas in the laboratory poses a great safety hazard to experimenters. Once the laboratory waste gas is inhaled into the human body, it will cause damage to human organs.

[0003] At present, the main method of exhaust gas treatment in laboratories is to exhaust through exhaust devices, which requires the construction of a ventilation tower on the top of the building to achieve exhaust. The cost investment is high, and the energy consumption in long-term operation is too large, which does not comply with the current environmental protection policy.

[0004] Therefore, it is urgent to research and develop an environmentally friendly universal exhaust device to solve the above technical problems. Summary of the invention

[0005] The present invention aims to provide an environmentally friendly universal exhaust device, which can reduce the cost of laboratory waste gas treatment.

[0006] In order to achieve the above-mentioned purpose, the present invention provides an environmentally friendly universal exhaust device, and the specific implementation scheme is as follows:

[0010] Compared with the prior art, the environmentally friendly universal exhaust device of the present invention can adjust the wind speed by setting a frequency conversion switch on the first pipe. The operating speed of the first fan is adjusted according to the exhaust gas emission speed requirements under specific circumstances. The exhaust gas is filtered and purified by a filter component and then discharged directly through the exhaust gas emission pipe. For the exhaust gas emission of a single laboratory, it only needs to set the exhaust hood at the exhaust outlet position of the laboratory. Compared with the prior art method of setting a ventilation tower on the top of the building, the cost investment is lower.

[0012] After the exhaust gas is filtered through the filter box, the second fan draws the exhaust gas from the filter box and sends it into the exhaust gas discharge pipe for discharge, thereby improving the exhaust gas discharge efficiency.

[0013] In some of the embodiments, an activated carbon filter layer is provided in the filter box.

[0014] By using an activated carbon filter layer to filter the exhaust gas, stable filtration of the exhaust gas is ensured.

[0016] By using a universal adjustment tube to adjust the setting direction of the pipeline and cooperating with a telescopic tube to adjust the distance between the exhaust hood and the universal adjustment component, it is adapted to different usage scenarios and the scope of application is improved.

[0017] In some embodiments, the universal adjustment tube includes a steering bearing tube and a connecting pipe, the connecting pipe is rotatably connected to the steering bearing tube, and the other end is connected to the steering bearing tube of another universal adjustment tube or connected to the first pipe.

[0018] By adopting the steering bearing tube and the connecting pipe, the angle adjustment of the exhaust hood of the pipe and the connecting pipe is achieved by utilizing the rotation connection between the connecting pipe and the steering bearing tube.

[0019] In some embodiments, a connecting end is provided on the steering bearing tube, the connecting end is rotatably connected to the steering bearing tube, and the end of the connecting pipe is sleeved on the connecting end or the connecting end is sleeved on the connecting pipe.

[0020] By adopting the rotational connection between the connecting end and the steering bearing tube and the connecting pipe and the connecting end, the rotational connection between the connecting pipe and the steering bearing tube is achieved, thereby improving the adjustment convenience and disassembly convenience of the universal adjustment component.

[0021] In some embodiments, the telescopic tube includes a fixed end and a telescopic end, the fixed end is connected to the steering bearing tube, and the telescopic end is plug-fitted with the fixed end and telescopes in the axial direction of the fixed end.

[0023] In some of the embodiments, the fixed end is rotatably connected to the steering bearing tube.

[0024] By arranging the fixed end to be rotatably connected to the steering bearing tube, the adjustment angle range of the universal adjustment component is further increased.

[0025] In some of the embodiments, a plurality of positioning holes are provided on the outer wall of the telescopic end, and elastic glass beads are provided on the inner wall of the fixed section, and the elastic glass beads are positioned and matched with the positioning holes.

[0026] The telescopic fixation of the fixed end and the telescopic end is achieved by using elastic glass beads and positioning holes, thereby improving the controllability of the telescopic and the stability of the telescopic tube.

[0027] Based on the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0028] By setting a frequency conversion switch on the first pipeline, the wind speed can be adjusted. The operating speed of the first fan can be adjusted according to the exhaust gas emission speed requirements under specific circumstances. The exhaust gas is filtered and purified by the filter component and then discharged directly through the exhaust gas emission pipeline. For the exhaust gas emission of a single laboratory, it only needs to set the exhaust hood at the exhaust outlet position of the laboratory. Compared with the prior art method of setting a ventilation tower on the top of the building, the cost investment is lower. BRIEF DESCRIPTION OF THE DRAWINGS
