[0021] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solutions of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] like Figure 1 and Figure 3 As shown, a waste gas collection and treatment device for a pharmaceutical workshop includes a first main line 1 and a second main line 2. The first main line 1 and the second main line 2 extend from outside the pharmaceutical workshop to inside the pharmaceutical workshop. A plurality of branch pipes 3 are connected to the first main line 1 and the second main line 2. The first main line 1 and the second main line 2 are laid at high altitude in the workshop. The upper ends of the branch pipes 3 are connected to the upper side of the main line. The branch pipes 3 extend from top to bottom.

The upper end of the universal positioning bamboo tube 32 is connected to the fixed pipe 31, and the lower end of the universal positioning bamboo tube 32 is provided with a circular cover to facilitate the collection of waste gas.

For example, the bamboo tube suction arm produced by Qingdao Lanshi Environmental Protection Equipment Co., Ltd. can be customized in length and the pipe diameter is 50mm-200mm. The first main line 1 is close to the atmospheric pressure reactor 91, and the second main line 2 is close to the high-pressure reactor 92. The positions of the multiple branch pipes 3 on the first main line 1 correspond to the multiple atmospheric pressure reactors 91, and the positions of the multiple branch pipes 3 on the second main line 2 correspond to the multiple high-pressure reactors 92. The universal positioning bamboo tube 32 is aligned with the direction of the reactor so that the reactor exhaust can be absorbed, the collection effect is improved, and the reactor exhaust gases of different properties are collected separately.

[0023] like Figure 1 and Figure 2As shown, the first main line 1 is provided with a first spray tower 11, a first adsorption box 12, a first fan 13 and a first chimney 14. The first spray tower 11, the first adsorption box 12, the first fan 13 and the first chimney 14 are connected in sequence. Under the action of the first fan 13, the exhaust gas collected by the branch pipe 3 enters the first spray tower 11 along the first main line 1. The first spray tower 11 selects an alkaline spray tower or an acid spray tower according to the nature of the exhaust gas. After being sprayed by the first spray tower 11, it enters the first adsorption box 12. Honeycomb activated carbon is provided in the first adsorption box 12. There are two first adsorption boxes 12. Harmful substances such as volatile organic compounds in the exhaust gas can be removed through the two first adsorption boxes 12. The exhaust gas after adsorption treatment is discharged from the first chimney 14 under the action of the first fan 13, and can be directly discharged into the atmosphere if it meets environmental protection requirements. The second main line 2 is provided with a second spray tower 21, a second adsorption box 22, a second fan 23 and a second chimney 24. The second spray tower 21, the second adsorption box 22, the second fan 23 and the second chimney 24 are also connected in sequence and have the same function as the equipment on the first main line 1. Under the action of the second fan 23, the exhaust gas collected by the branch pipe 3 enters the second spray tower 21 along the second main line 2. The type of spray liquid and the internal structure of the spray tower of the second spray tower 21 are selected according to the type of tail gas from the corresponding high-pressure reactor 92. After being sprayed by the second spray tower 21, the exhaust gas enters the second adsorption box 22. There are also two second adsorption boxes 22. After being adsorbed by the two second adsorption boxes 22, the exhaust gas is discharged from the second chimney 24 under the action of the second fan 23, and can be directly discharged into the atmosphere when environmental protection requirements are met.

[0024] like Figure 1 and Figure 2 As shown, the pipeline at the inlet end of the first fan 13 is connected to the pipeline at the inlet end of the second fan 23 through the intermediate pipe 4. The intermediate pipe 4 is provided with an intermediate valve 41, which is normally closed. The first main line 1 is provided with a third shut-off valve 67, and the second main line 2 is provided with a fourth shut-off valve 68. The two shut-off valves are used to close or open the corresponding pipelines. When a fan is damaged, the other fan can be used to drive the exhaust, close the shut-off valve on the corresponding pipeline of the working fan, and open the intermediate valve 41, so that the first fan 13 and the second fan 23 serve as backup for each other.

[0025] like Figure 1 and Figure 2As shown, the first main line 1 and the second main line 2 are connected to the vacuum device 5, and the vacuum device 5 includes a condenser 51, a vacuum buffer tank 52 and a vacuum pump 53. The first main line 1 is connected to the condenser 51 through a first vacuum line 61, and the first vacuum line 61 is provided with a first vacuum valve 611. The second main line 2 is connected to the condenser 51 through a second vacuum line 62, and the second vacuum line 62 is provided with a second vacuum valve 621. The condenser 51 is provided with a cold water inlet and outlet. External cold water enters the condenser 51 to exchange heat with the exhaust gas, so that the pollutants in the steam state are condensed and separated from the exhaust gas. The condenser 51 is connected to the vacuum buffer tank 52, and the vacuum buffer tank 52 can buffer pressure fluctuations and A gas-liquid separator is performed, the vacuum buffer tank 52 is connected to the vacuum pump 53, the outlet end of the vacuum pump 53 is connected to the first main line 1 through a first outlet pipe 63, the first outlet pipe 63 is provided with a first outlet valve 631, the outlet end of the vacuum pump 53 is connected to the second main line 2 through a second outlet pipe 64, the second outlet pipe 64 is provided with a second outlet valve 641, the exhaust gas enters the first main line 1 or the second main line 2 through the vacuum pump 53, a first shut-off valve 65 is provided on the pipe section between the connection of the first vacuum line 61 and the connection of the first outlet pipe 63 on the first main line 1, and a second shut-off valve 66 is provided on the pipe section between the connection of the second vacuum line 62 and the connection of the second outlet pipe 64 on the second main line 2. When the vacuum device 5 is not in use, the first vacuum valve 611, the second vacuum valve 621, the first outlet valve 631, and the second outlet valve 641 are all closed, the first shut-off valve 65 and the second shut-off valve 66 are opened, and the exhaust gas generated by the atmospheric pressure reactor 91 is discharged from the first main line 1, while the exhaust gas generated by the high-pressure reactor 92 is discharged from the second main line 2. When high-concentration gas is generated in the atmospheric pressure reactor 91 or the high-pressure reactor 92, for example, when high-concentration gas is generated in the high-pressure reactor 92, the vacuum device 5 is put into use, the corresponding second shut-off valve 66 is closed, the second vacuum valve 621 is opened, and the vacuum pump 53 is operated. The high-concentration exhaust gas enters the condenser 51, where the pollutants in the vapor state are condensed and separated from the exhaust gas. The exhaust gas then passes through the vacuum buffer tank 52 and the vacuum pump 53 and returns to the second main line 2 to continue being treated by the second spray tower 21 and the second adsorption box 22. Since the concentration of the high-concentration exhaust gas is reduced after pre-treatment by the vacuum device 5, the treatment effect can be improved and the service life of the spray liquid in the second spray tower 21 and the activated carbon in the second adsorption box 22 can be extended. High-concentration gas is generated in the atmospheric pressure reactor 91. Similarly, the corresponding valve is opened to allow the high-concentration gas to pass through the vacuum device 5 and then return to the first main pipeline 1 for treatment.

These improvements and modifications should also be regarded as within the scope of protection of the present invention.
