Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to an organic waste gas treatment system based on photocatalysis coupled with microorganisms. Background Art

[0002] Photocatalysis coupled microbial technology is an innovative environmentally friendly technology that combines the advantages of photocatalysis and microbial technology to achieve a more efficient and environmentally friendly pollutant treatment process.

[0003] Photocatalytic coupled microbial technology is usually used to treat pollutants in waste gas. During treatment, the waste gas, photocatalyst and microorganisms need to be placed in a sealed space at the same time. The electron-hole pairs generated by the photocatalyst under light conditions can trigger a series of redox reactions to generate active substances with strong oxidizing properties. These active substances can destroy the molecular structure of pollutants, making them easier to be degraded by microorganisms. At the same time, microorganisms use these degradation products as a nutrient source for growth and reproduction, and further degrade pollutants; however, in the existing waste gas treatment process, the photocatalyst, microorganisms and waste gas are all stationary. The photocatalyst and microorganisms can only treat the waste gas near them first, and then gradually treat other parts of the waste gas. The treatment process will consume a lot of time and the treatment efficiency is low. Summary of the invention

The elastic force of the fourth spring 46 is greater than the elastic force of the fifth spring 47. The second telescopic rods 40 on the front and rear sides are respectively located directly below the two air-permeable grooves 15 on the sealing plate 14. During operation, when the sealing plate 14 is sealed and moves downward, the exhaust gas at the bottom of the exhaust gas treatment tube 3 will be discharged and new exhaust gas will be drawn in from the upper position of the exhaust gas treatment tube 3; when the exhaust gas treatment tube 3 moves to the bottommost position, since the air permeable groove 15 on the sealing plate 14 is sealed by the sliding plate 16, the sliding plate 16 will press the second telescopic rods 40 on the front and rear sides downward, and since the elastic force of the fourth spring 46 is greater than the elastic force of the fifth spring 47, the second telescopic rod 40 will first drive the connecting ring 41 to move downward when it contracts, and when the connecting ring 41 moves downward, it will drive the sliding ring 43 to move to a position close to the ratchet 39 through the connecting rod 42, and the sliding ring 43 will drive the pawl 44 to start meshing with the ratchet 39 ; After the pawl 44 engages with the ratchet 39, the first threaded cylinder 19 will drop to a position where it engages with the second threaded rod 38. At this time, the second threaded rod 38 cannot rotate and therefore drives the first threaded cylinder 19 to rotate. When the first threaded cylinder 19 rotates, it will drive the rotating ring 18 to rotate. When the rotating ring 18 rotates, it will drive the six sliding plates 16 to slide to the outer position through the six arc-shaped guide frames 20 respectively; when the sliding plate 16 slides to the outermost position, the sliding plates 16 at the front and rear positions just disengage from the second telescopic rod 40 on the front and rear sides. At this time, the two pawls 44 begin to disengage from the ratchet 39, the second threaded rod 38 can rotate normally, and the sealing plate 14 will normally disengage from the second threaded rod 38 when it moves upward.

When the first valve core 50 moves to the left position, the first valve 48 opens, and when the two second valve cores 51 move to the left position, the two second valves 49 are closed. At this time, the second air pipe 6 is connected with the detection cylinder 4 and the left exhaust gas treatment cylinder 3; when the exhaust gas treatment cylinders 3 on the left and right sides are ventilated, the unqualified gas in the detection cylinder 4 will be drawn into the left exhaust gas treatment cylinder 3 again for further treatment.
