However, since the air outlet of the exhaust fan is far away from the source of the harmful gases, and the position of the harmful gases changes due to changes in the placement of the test instruments, the adsorption effect is poor, and some harmful gases will still diffuse into the laboratory.

[0033] Implementation Method 1

[0034] Reference Figures 1 to 3 , this embodiment is an optional embodiment of the present application, which discloses a test bench exhaust gas recovery and treatment device, including a test bench 1;

[0035] The top surface of the test bench 1 is provided with a protective cover 2, and the protective cover 2 includes a support frame 201, which is connected to the top surface of the test bench 1; the support frame 201 is a square structure, and baffles 202 are provided on the top and each side thereof. The baffles 202 are made of tempered glass or other transparent plates. It should be noted that the baffles 202 can also be made of opaque plates such as stainless steel;

[0036] An operation window 203 is also provided on any of the baffles 202. It should be noted that the operation window 203 can also be provided by removing the baffle 202 on one side of the support frame 201.

[0037] An exhaust hole 7 is provided on the baffle 202 at the top of the protective cover 2. The exhaust gas recovery and treatment device further includes a negative pressure exhaust module, which includes an exhaust pipe 5 and an exhaust fan 6. The inlet end of the exhaust pipe 5 is connected to the exhaust hole 7, and the exhaust fan 6 is provided in the exhaust pipe 5.

[0038] At the same time, an adsorption tube 8 is also provided at the outlet end of the exhaust pipe 5. The outer surface of the adsorption tube 8 is provided with a plug-in groove 12. The plug-in groove 12 cooperates with the exhaust pipe 5 to achieve plug-in connection between the adsorption tube 8 and the exhaust pipe 5. Along the direction of air flow, activated carbon 9, silica gel 10 and molecular sieve adsorbent 11 are sequentially provided in the adsorption tube 8.

[0039] The above arrangement not only ensures a stable connection between the adsorption tube 8 and the exhaust pipe 5 , but also enables quick installation and removal of the adsorption tube 8 , which is beneficial for the replacement of various adsorbents.

[0040] Secondly, the use of multiple adsorbents can adsorb different types of harmful gases, avoiding environmental pollution caused by direct discharge of harmful gases.

[0041] The exhaust gas recovery and treatment device also includes an adjustment frame 3, which includes two slide rails 301. The two slide rails 301 are respectively placed on both sides of the operating window 203; a slide seat 302 is provided on each of the slide rails 301, and the two slide seats 302 are connected by a plurality of connecting rods 303. It should be noted that two connecting rods 303 are provided, and an adjustment seat 4 is provided between the two connecting rods 303. The adjustment seat 4 is slidably connected to the two connecting rods 303 respectively;

[0042] The above structure ensures that the adjustment seat 4 can slide in the horizontal direction and in the longitudinal direction within the horizontal plane, thereby controlling the adjustment seat 4 to move to any position within the horizontal plane.

[0043] Furthermore, a locking screw 13 is threadedly connected to both the slide 302 and the adjustment seat 4. When the slide 302 and the adjustment seat 4 are adjusted into place, the locking screw 13 can fix their positions, thereby preventing the adjustment seat 4 from sliding due to external forces during normal use, thereby improving the stability and reliability of the device.

[0044] A connecting sleeve 14 is further provided on the adjusting seat 4. The connecting sleeve 14 is located between the two connecting rods 303. Both upper and lower ends of the connecting sleeve 14 are opened. The top of the connecting sleeve 14 is connected to the exhaust hole 7 via an air suction hose 15, and the bottom of the connecting sleeve 14 is connected to the adsorption module.

[0045] It should be noted that the length of the suction hose 15 needs to be increased to ensure that the adjustment seat 4 can slide to any position in the horizontal plane;

[0046] The adsorption cover 16 and the stainless steel bellows 17 are provided. The adsorption cover 16 is a conical structure. The adsorption cover 16 and the stainless steel bellows 17 are connected by a quick connector 18. The other end of the stainless steel bellows 17 is connected to the bottom of the connecting sleeve 14.

[0047] The adsorption cover 16 with a conical structure can effectively improve the air suction capacity at the gas inlet end, avoid the diffusion of harmful gases, and help improve the recovery effect of harmful gases;

[0048] Secondly, the stainless steel bellows 17 not only has a certain flexibility, which makes it easy to bend according to actual conditions, and further adjust the position of the adsorption cover 16 to make it fit more closely with the source of harmful gases; at the same time, it also has a certain rigidity, and after bending, it can better maintain its shape, thereby ensuring the stability of the position of the adsorption cover 16.

[0049] Finally, the stainless steel bellows 17 are widely available and can effectively reduce the cost of the entire equipment.

[0050] Further, refer to Figure 4 The adsorption module includes an adsorption cover 16, an air suction pipe 19 and a shaping hose 20. The adsorption cover 16 has a conical structure. The adsorption cover 16 and the air suction pipe 19 are connected by a quick connector 18. One end of the shaping hose 20 is connected to the adjustment seat 4, and the air suction pipe 19 is connected to the connecting sleeve 14.

[0051] The air intake pipe 19 is a hose, and the air intake pipe 19 is tied to the shaped hose 20 by a plurality of tie ties 21 .

[0052] The above structure not only ensures the effective connection between the adsorption hood 16 and the exhaust pipe 5, but also the shaped hose 20 has both flexibility and rigidity, which ensures the adjustability of the intake pipe 19 while ensuring the stable position of the adjusted adsorption hood 16.

[0053] During use, the staff conducts test operations in the protective cover, turns on the negative pressure exhaust module, and controls the position of the adsorption module through the adjustment frame and the adjustment seat. At the same time, the adsorption cover is placed directly above the source of the harmful gas by changing the shape of the shaped hose or the stainless steel bellows, thereby ensuring that the adsorption cover is always in the best adsorption position;

[0054] Compared with the prior art method of only providing an air suction device at the top, the present application extends the negative pressure exhaust module at the top through the adsorption module, thereby bringing the adsorption module closer to the source of the harmful gas. As soon as the harmful gas is generated, it is extracted from the test bench through negative pressure, thereby preventing the spread of the harmful gas and improving the recovery effect of the harmful gas.

[0055] Secondly, this application can not only adapt the position of the adsorption module before the experiment, but also make temporary adjustments according to the actual generation of harmful gases during the experiment, further improving the adjustability of the equipment and improving the recovery effect of harmful gases.

[0056] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
