Description

Technical Field

[0001] The present invention relates to the technical field of waste gas collection, and particularly relates to a method and system for treating and collecting waste gas from residual packaging in a locally enclosed kettle. Background Art

[0002] In the process of pesticide production, the packaging of kettle residues (residues in the reaction kettle) is an important link, but a large amount of volatile organic compounds (VOCs), toxic gases and odor substances will be generated during this process. In the prior art, the waste gas treatment mainly adopts the following two methods:

[0003] Open packaging: directly filling the kettle residues into an open iron barrel, and the waste gas escapes directly into the environment without being collected, resulting in environmental pollution and safety hazards;

[0004] Overall enclosed room: designing the packaging area as a fully enclosed space and collecting the waste gas through a large-scale ventilation system. Although it can reduce the escape of waste gas, there are problems of high energy consumption and inconvenient operation.

[0005] In summary, the traditional methods for packaging kettle residues in the process of pesticide production do not simultaneously have the effects of high efficiency, low energy consumption and low operation risk. Summary of the Invention

The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0024] Please refer to Figure 1 , the present invention provides a local closed kettle residue packaging waste gas treatment and collection system. The local closed kettle residue packaging waste gas treatment and collection system includes a concentration kettle 1, a kettle residue pipeline, a closed room 4, an iron barrel 9, a floor scale 16, and an exhaust gas collection unit 15. The floor scale 16 is installed at the inner bottom of the closed room 4, and the iron barrel 9 is placed above the floor scale 16. The top of the iron barrel 9 is provided with a feed inlet 10. The bottom of the concentration kettle 1 is provided with the kettle residue pipeline, and a discharge switch valve 3 is arranged on the kettle residue pipeline. The end of the discharge pipeline far from the concentration kettle 1 corresponds to the feed inlet 10. A floor scale operation column 17 is also arranged on the side of the closed room 4, and the floor scale operation column 17 is electrically connected to the floor scale 16;

[0025] An exhaust gas outlet hole 11 is further arranged at the top of the closed room 4. An exhaust gas discharge pipeline is hermetically installed at the exhaust gas outlet hole 11. The end of the exhaust gas discharge pipeline far from the exhaust gas outlet hole 11 is connected to the exhaust gas collection unit 15. A butterfly valve 13 is arranged on the exhaust gas discharge pipeline. A hose support 8 is arranged inside the closed room 4, and the hose support 8 is used to place the end of the metal hose 7 far from the kettle residue discharge pipe 2.

[0026] In this embodiment, before packaging the kettle residue, the operator sets the packaging weight through the floor scale operation column 17 and opens the butterfly valve 13 to make the inside of the closed room 4 form a negative pressure. Then, after the operator unscrews the lid of the iron barrel 9, the iron barrel 9 is placed on the floor scale 16 by a hydraulic truck. The operator is outside the closed room 4 and places the end of the kettle residue pipeline far from the concentration kettle 1 into the feed inlet 10. When the closed room 4 is in a closed state, the discharge switch valve 3 is opened, and the kettle residue in the concentration kettle 1 is discharged into the iron barrel 9 through the kettle residue pipeline. When the floor scale 16 detects that the weight of the kettle residue in the iron barrel 9 reaches a preset value, the discharge switch valve 3 is interlocked and closed. After waiting for 5 minutes, the closed room 4 is opened. After the operator removes the kettle residue pipeline from the feed inlet 10, it is placed on the hose support 8. The lid of the iron barrel 9 is tightened, and the packaged iron barrel 9 is taken out of the closed room 4 by a hydraulic truck, and the butterfly valve 13 is closed, realizing effective collection of waste gas during the local closed kettle residue packaging process. By adopting this technical solution, effective collection and treatment of waste gas generated during kettle residue packaging can be achieved, thereby reducing energy consumption and at the same time reducing the occupational health risk of personnel.

[0027] Further, the residue pipeline includes a residue discharge pipe 2 and a metal hose 7. One end of the residue discharge pipe 2 is connected to the bottom of the concentration kettle 1, and the other end of the residue discharge pipe 2 is provided with the metal hose 7. A discharge switch valve 3 is arranged on the residue discharge pipe 2, and the end of the metal hose 7 away from the residue discharge pipe 2 corresponds to the feed inlet 10.

[0028] Further, the waste gas exhaust pipeline includes a waste gas collection heat-resistant bellows 12 and a waste gas stainless steel pipe 14. One end of the waste gas collection heat-resistant bellows 12 is hermetically installed at the waste gas outlet hole 11, and the other end of the waste gas collection heat-resistant bellows 12 is connected to the waste gas collection unit 15 through the waste gas stainless steel pipe 14. A butterfly valve 13 is arranged on the waste gas stainless steel pipe 14.

[0029] Further, an external door 6 is also arranged at the end of the enclosed room 4, and an observation window 5 is arranged at the top of the external door 6, and the observation window 5 corresponds to the top of the iron bucket 9.

[0030] In this embodiment, through the arrangement of the external door 6, it is convenient to place and take out the iron bucket 9, and through the arrangement of the observation window 5, it is convenient to observe the internal situation of the enclosed room 4.

[0031] Please refer to Figure 2 , the present invention also provides a method for treating and collecting waste gas from the residue packaging of a partially enclosed kettle, which is applied to the system for treating and collecting waste gas from the residue packaging of a partially enclosed kettle as described above, and includes the following steps:

[0032] S1: Before packaging the residue of the kettle, the operator sets the packaging weight through the weighing operation column 17 and opens the butterfly valve 13 to form a negative pressure in the enclosed room 4.

[0033] S2: After the operator unscrews the lid of the iron bucket 9, the iron bucket 9 is placed on the weighing scale 16 through a hydraulic truck. The operator is outside the enclosed room 4 and places the end of the residue pipeline away from the concentration kettle 1 into the feed inlet 10.

[0034] S3: After the enclosed room 4 is in a closed state, the discharge switch valve 3 is opened, and the residue in the concentration kettle 1 is discharged into the iron bucket 9 through the residue pipeline.

[0035] S4: When the weighing scale 16 detects that the weight of the residue in the iron bucket 9 reaches a preset value, the discharge switch valve 3 is interlocked and closed. After waiting for 5 minutes, the enclosed room 4 is opened. The operator removes the residue pipeline from the feed inlet 10 and places it on the hose bracket 8, and tightens the lid on the iron bucket 9.

[0036] S5: Use a hydraulic truck to take out the packaged iron drum 9 from the enclosed room 4, and close the butterfly valve 13 to effectively collect the waste gas during the packaging process of the residue in the local closed kettle.

[0037] In this embodiment, before packaging the residue in the kettle, the operator sets the packaging weight through the weighing scale operation column 17, and opens the butterfly valve 13 to form a negative pressure in the enclosed room 4. Then, after the operator unscrews the lid of the iron drum 9, the iron drum 9 is placed on the weighing scale 16 by a hydraulic truck. The operator places the end of the kettle residue pipeline away from the concentration kettle 1 into the feed port 10 outside the enclosed room 4. When the enclosed room 4 is in a closed state, the discharge switch valve 3 is opened, and the kettle residue in the concentration kettle 1 is discharged into the iron drum 9 through the kettle residue pipeline. When the weighing scale 16 detects that the weight of the kettle residue in the iron drum 9 reaches the preset value, the discharge switch valve 3 is interlocked and closed. After waiting for 5 minutes, the enclosed room 4 is opened. The operator removes the kettle residue pipeline from the feed port 10 and places it on the hose bracket 8. Tighten the lid on the iron drum 9, use a hydraulic truck to take out the packaged iron drum 9 from the enclosed room 4, and close the butterfly valve 13 to effectively collect the waste gas during the packaging process of the residue in the local closed kettle. With this technical solution, due to the small enclosed area and space, the energy consumption of the waste gas collection system is reduced. A negative pressure is formed in the enclosed space, which can prevent the waste gas from spreading and triggering the flammable and toxic alarm outside the enclosed room 4, causing environmental pollution. At the same time, during the packaging process of the kettle residue, personnel do not need to enter, and the operation process is carried out under negative pressure to protect the occupational health of personnel and avoid occupational health risks.
