Multi-condition switching pollution control device Technical Field
[0001] This utility model relates to the field of pollution control technology, and more specifically, to a multi-condition switching pollution control control device. Background Technology
[0002] With the rapid development of industries such as chemical engineering, coating, and printing, the types of gaseous pollutants generated during industrial production processes are numerous and the emission conditions are complex and variable. For example, in chemical synthesis reactions, the concentration and composition of volatile organic compounds (VOCs), acidic gases, and particulate matter in the waste gas vary significantly during the start-up, normal operation, and end stages of the reaction. In coating workshops, the concentration and composition of organic waste gas emitted also vary depending on the production batch and the application of different coatings.
[0003] Most existing gas pollution control equipment is designed for specific types and concentration ranges of gaseous pollutants, and the treatment mode is fixed and singular. When the type and concentration of gaseous pollutants change, these devices cannot flexibly adjust the treatment strategy and operating parameters, resulting in the exhaust gas not being able to enter the appropriate purification equipment in time, thus reducing the treatment efficiency. Summary of the Invention
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-condition switching pollution control device, which aims to solve the problems mentioned in the background art.

[0006] Furthermore, a partition is fixedly installed inside the mounting frame, and a filter screen is fixedly embedded in the top of the partition.
[0007] It can be seen that the above technical solution is designed to facilitate the filtration of impurities in the exhaust gas.
[0008] Furthermore, fixing plates are fixedly connected to both sides of the mounting frame near the bottom edge.
[0009] As can be seen, in the above technical solution, the mounting frame can be fixed by fixing the fixing plate with bolts.
[0010] Furthermore, the filter plate is provided with a rotating assembly, including a stepper motor, a rotating shaft, three stirring blades, a fixing ring, and a brush plate.
[0011] Furthermore, the stepper motor is fixedly installed at the top center of the mounting frame, and the output shaft end of the stepper motor is fixedly connected to the rotating shaft. The three stirring blades and the fixing ring are all fixedly installed on the rotating shaft, and the three stirring blades are all located at the bottom of the fixing ring.
[0012] Furthermore, the fixing ring is provided with bolts, and the fixing ring is fixed to the brush plate by bolts.
[0013] As can be seen, in the above technical solution, the brush plate is disassembled and replaced by rotating the bolt and moving it away from the brush plate.
[0014] Furthermore, a sealing plate is movably connected to the front side of the mounting frame via a snap fastener, and a transparent plate is fixedly embedded inside the sealing plate.

[0016] The technical effects and advantages of this utility model are as follows:
[0017] 1. This utility model allows exhaust gas to enter the installation frame through the inlet pipe by starting the exhaust fan and opening the first valve.

Finally, the solenoid valve at the corresponding position is opened, and the exhaust gas is discharged through the three-way pipe and one of the outlet pipes. The operation is simple, and the exhaust gas can enter the appropriate purification equipment in a timely manner, which improves the treatment efficiency.
[0018] 2. This utility model filters impurities in exhaust gas through a filter screen. A stepper motor drives a rotating shaft to rotate, which in turn drives three stirring blades to rotate. The three stirring blades ensure that the exhaust gas is evenly distributed within the mounting frame, facilitating detection of the exhaust gas by a gas detector. At the same time, the rotating shaft drives a fixing ring and a brush plate to rotate. The brush bristles at the bottom of the brush plate clean impurities from the top of the filter screen. The operation is simple and convenient. Attached Figure Description

A switching component 4 is provided on the exhaust fan 12. The switching component 4 includes a three-way pipe 401, multiple air outlet pipes 402, multiple solenoid valves 403, and two second valves 404. One end of the three-way pipe 401 is fixedly connected to the output end of the exhaust fan 12. One end of each of the multiple air outlet pipes 402 is fixedly connected to the three-way pipe 401. Multiple solenoid valves 403 are respectively fixedly installed on the multiple air outlet pipes 402, and the multiple solenoid valves 403 are all located between the two second valves 404.

[0028] Furthermore, a partition 9 is fixedly installed inside the mounting frame 1, and a filter plate 10 is fixedly embedded in the top of the partition 9. Fixing plates 8 are fixedly connected to both sides of the mounting frame 1 near the bottom edge.
[0029] Furthermore, the filter plate 10 is provided with a rotating assembly 5, a stepper motor 501, a rotating shaft 502, three stirring blades 503, a fixing ring 504, and a brush plate 505. The stepper motor 501 is fixedly installed at the top center of the mounting frame 1, and the output shaft end of the stepper motor 501 is fixedly connected to the rotating shaft 502. The three stirring blades 503 and the fixing ring 504 are all fixedly installed on the rotating shaft 502, and the three stirring blades 503 are all located at the bottom of the fixing ring 504. The fixing ring 504 is provided with bolts 506, and the fixing ring 504 and the brush plate 505 are fixed together by bolts 506. The front side of the mounting frame 1 is movably connected to a sealing plate 6 by a snap fastener, and a transparent plate 7 is fixedly embedded inside the sealing plate 6.
[0030] The system filters impurities in the exhaust gas through the filter screen plate 10. The stepper motor 501 is activated, driving the rotating shaft 502 to rotate, which in turn drives the three stirring blades 503 to rotate. The three stirring blades 503 ensure that the exhaust gas is evenly distributed within the mounting frame 1, facilitating detection by the gas detector 11.

[0032] In use, the external pipe is connected to the air inlet pipe 2 with bolts, and the fixing plate 8 is fixed with bolts, thereby fixing the mounting frame 1. The exhaust fan 12 is started and the first valve 3 is opened. Under the negative pressure generated by the exhaust fan 12, the exhaust gas can enter the mounting frame 1 through the air inlet pipe 2. The gas detector 11 is then started and operates to detect the exhaust gas. Since the gas detector 11 integrates a gas sensor array, it can simultaneously and quickly detect and analyze multiple pollutants, such as volatile organic compounds (VOCs), sulfur dioxide, and nitrogen oxides. The gas detector 11 transmits real-time detection data. The control system has a built-in expert database that can automatically match the optimal treatment plan based on the type and concentration of detected gaseous pollutants. It also sends control commands to the solenoid valve 403 as needed. When the solenoid valve 403 receives the opening signal, it quickly opens the corresponding channel, and the exhaust gas is discharged through the three-way pipe 401 and one of the outlet pipes 402. The operation is simple, and the exhaust gas can enter the appropriate purification equipment in time, which improves the treatment efficiency. The other three-way pipe 401 can be installed in front of one of the three-way pipes 401 by bolts, thereby extending the length of the three-way pipe 401.
