Through the setting of the disinfection mechanism 7, the neutralized and purified gas can be finally disinfected. After the waste gas is generated in the laboratory, the smoke exhaust gas sensor 5 on the air duct 4 detects the waste gas and then controls the induced draft fan 6 to start and suck the waste gas into the internal alkali washing tower 1 through the air duct 4, and then starts the first pump body 3 to transport the alkali solution in the alkali washing tank 2 to the alkali washing tower 1 to spray and purify the waste gas. The purified gas is discharged outward by the induced draft fan 6. When the gas is discharged, the gas enters the disinfection box 9. At this time, the second pump body 11 is started again to spray the disinfectant in the disinfectant loading box 10 into the disinfection box 9 through the spray pipe 12, and the motor 13 is started to drive the stirring rod 14 to stir and mix the waste gas and the disinfectant, so that the waste gas is disinfected before being discharged outward, so as to improve the quality of waste gas treatment and avoid harmful gas discharge to pollute the environment.

[0025] The number of motors 13 and stirring rods 14 is set to two, and they are symmetrically distributed on both sides of the disinfection box 9. Support frames 15 are fixedly installed on the top and bottom of the mounting plate 8. A screw 16 is movably installed on the top of the support frame 15. A threaded support plate 17 is provided on the screw 16. Two plug rods 18 are fixedly installed on the support plate 17. A plurality of limit blocks 19 are fixedly installed on the surface of the disinfection box 9. The plug rods 18 are slidably connected to the support frame 15, and the plug rods 18 and the limit blocks 19 are engaged with each other. By setting the motor 13 and the stirring rod 14 to two and symmetrically setting them, the stirring range of the stirring rod 14 in the disinfection box 9 can be improved, so that the disinfectant can be better mixed with the exhaust gas. By setting the support frame 15, the screw 16, the support plate 17, the plug 18 and the limit block 19, the rotating screw 16 can simultaneously drive the two plugs 18 to rise and fall through the support plate 17, so that the two plugs 18 are engaged and separated with the limit block 19, which can replace the traditional cumbersome installation steps and simplify the operation during installation. In addition, it is highly firm and can be easily disassembled, so that the inside of the disinfection box 9 is easy to clean.

[0026] A viewing window 20 is installed on one side of the disinfectant loading box 10, a fixing plate 21 is fixedly installed on both sides of the mounting plate 8, a positioning rod 22 is fixedly installed on the fixing plate 21, and a positioning plate 23 used in conjunction with the positioning rod 22 is fixedly installed on both sides of the disinfectant box 9, and an insert block 24 is fixedly installed at one end of the positioning rod 22, and the shape of the insert block 24 is set to be conical. Through the setting of the viewing window 20, it is convenient to check the remaining amount of disinfectant inside the disinfectant loading box 10, so that it can be added in time. Through the setting of the fixing plate 21, the positioning rod 22 and the positioning plate 23, the disinfectant box 9 can be pre-positioned when it is installed. Before installation, the positioning rod 22 is inserted into the positioning plate 23. After positioning, it is convenient to make the insert rod 18 easier to insert into the limit block 19, which is convenient for installing the disinfectant box 9. Through the setting of the insert block 24, because the shape of the insert block 24 is conical, the area of ​​the bottom is smaller than the area of ​​the top, so it is easier to drive the positioning rod 22 to be inserted into the positioning plate 23.

[0027] In this embodiment, if Figure 1-Figure 4 As shown, the working process of a laboratory waste gas emergency purification treatment device provided in this embodiment is as follows:

[0028] After the waste gas is generated in the laboratory, the smoke exhaust gas sensor 5 on the air duct 4 detects the waste gas and then controls the induced draft fan 6 to start and suck the waste gas into the internal alkali washing tower 1 through the air duct 4, and then starts the first pump body 3 to transport the alkali solution in the alkali washing tank 2 to the alkali washing tower 1 to spray and purify the waste gas, and the purified gas is discharged outward by the induced draft fan 6. When the gas is discharged, the gas enters the disinfection box 9. At this time, the second pump body 11 is started again to spray the disinfectant in the disinfectant loading box 10 into the disinfection box 9 through the spray pipe 12, and the motor 13 is started to drive the stirring rod 14 to stir and mix the waste gas and the disinfectant, so that the waste gas is disinfected before being discharged outward.

[0029] In summary, in this embodiment, according to a laboratory waste gas emergency purification treatment device of this embodiment, by setting the motor 13 and the stirring rod 14 to two and symmetrically setting them, the stirring range of the stirring rod 14 in the disinfection box 9 can be improved, so that the disinfectant can be better mixed with the waste gas, and through the setting of the support frame 15, the screw 16, the support plate 17, the insertion rod 18 and the limit block 19, the rotating screw 16 can simultaneously drive the two insertion rods 18 to rise and fall through the support plate 17, so that the two insertion rods 18 are engaged and separated with the limit block 19, which can replace the traditional cumbersome installation steps, simplify the operation during installation, and have high firmness and can also be convenient for disassembly. , it is convenient to clean the inside of the disinfection box 9. Through the setting of the window 20, it is convenient to check the remaining amount of disinfectant in the disinfectant loading box 10, so that it can be added in time. Through the setting of the fixing plate 21, the positioning rod 22 and the positioning plate 23, the disinfection box 9 can be pre-positioned when installed. Before installation, the positioning rod 22 is inserted into the positioning plate 23. After positioning, it is convenient to make the insertion rod 18 easier to insert into the limit block 19, which is convenient for installing the disinfection box 9. Through the setting of the insertion block 24, because the shape of the insertion block 24 is conical, the area of ​​its bottom is smaller than the area of ​​the top, so it is easier to drive the positioning rod 22 to be inserted into the positioning plate 23.
