DETAILED DESCRIPTION
[0014] The specific embodiments of the utility model will be specifically described below in combination with the drawings.
[0015] Embodiment:
[0016] The utility model discloses a kind of ultraviolet-biological coupling reactor's specific embodiments shown in the accompanying drawings, it mainly includes organic waste gas collecting device 1, organic waste gas collecting device 1 is connected with air inlet pipe 2, the other end of air inlet pipe 2 is connected with biological tower 4, and the top of biological tower 4 is connected with centrifugal fan 6.Industrial organic waste gas is collected after passing through organic waste gas collecting device 1, first enters air inlet pipe 2, then enters biological tower 4, and finally passes through centrifugal fan 6 and is discharged up to standard.
[0017] Specifically, air inlet pipe 2 is provided with ultraviolet lamp tube 3, and ultraviolet lamp tube 3 is in the shape of a stick. Ultraviolet lamp tube 3 has several roots, and the several ultraviolet lamp tubes 3 are fixed in the middle of the air inlet pipe 2 by a support. Ultraviolet lamp tube 3 is used to oxidize organic waste gas into small molecular substances that are better utilized by microorganisms.
[0018] The biological tower 4 is provided with a filler layer 5, and a spray pipe 13 is arranged above the filler layer 5 in the biological tower 4. The spray pipe 13 is connected to the bottom of the biological tower 4 through a circulating pipeline 14, and a circulating pump 15 is arranged on the circulating pipeline 14. The organic waste gas flows upward through the filler layer 5, and the spray pipe 13 sprays, and the standard waste gas is discharged from the top of the biological tower 4.
[0019] The biological tower 4 is provided with a pH meter 7, and a drainage electric valve 8 is connected to the drainage outlet of the biological tower 4. A float ball valve 9 is arranged in the biological tower 4, and the float ball valve 9 is connected to a water supplement tank 10. During the operation of the reactor, the drainage electric valve 8 discharges water according to the pH value detected by the pH meter 7, and the drainage electric valve 8 is closed when the water level reaches a low value, and the float ball valve 9 is opened to supplement water to the biological tower 4 by the water supplement tank 10.
[0020] The biological tower 4 is connected to a medicament storage tank 11, and the medicament storage tank 11 is connected to the bottom of the biological tower 4 through a medicament adding pipeline 16. The medicament adding pipeline 16 is provided with a medicament adding pump 17, a safety valve 18, and a damper 19. The medicament storage tank 11 contains a composite medicament, which can periodically and regularly add nutrients required for microbial metabolism to the biological tower 4 by the medicament adding pump 17. The composite medicament in the medicament storage tank 11 is compounded by EM microbial agent, aquatic vitamin C, and composite water-soluble fertilizer according to a certain proportion, which can provide nutrients required for the operation of the biological tower 4 and the reproduction of the microbial species. The regularly added microbial agent only needs a small amount to meet the normal operation requirements of the biological tower 4.
[0021] The differential pressure transmitter 12 is connected to the bio-tower 4 above and below the filler layer 5. Under long-time operation, the microorganisms attached to the filler in the bio-tower 4 grow slowly, the bio-membrane thickens, the pressure loss of the filler increases, the metabolic mass transfer resistance of the microorganisms increases, and the tail gas removal effect decreases. Therefore, the differential pressure transmitter 12 can be used for detection, and the ultraviolet lamp tube 3 can be used for treatment. The trace ozone generated by the ultraviolet lamp tube 3 can kill the excessive microbial cells in the filler, and the excessive extracellular polymers secreted by the microorganisms can also be cleaned, so as to reduce the wind resistance, restore the normal operation of the bio-tower 4, and improve the waste gas treatment effect.
[0022] In the specific work of the utility model, the ultraviolet lamp tube 3 is always on at low power during the daily operation of the equipment, and the organic waste gas is oxidized into small molecular substances which are better utilized by microorganisms. When the differential pressure transmitter 12 exceeds the high set value, the ultraviolet lamp tube 3 increases the power and improves the ozone concentration in the gas. When the detection value of the differential pressure transmitter 12 decreases to the low set value, the ultraviolet lamp tube 3 returns to low power. It should be noted that the ozone concentration generated by the ultraviolet lamp tube 3 is low and unstable, and the air outlet of the air inlet pipe 2 must be directly connected to the air inlet of the bio-tower 4 to ensure the utilization efficiency of the ozone.
[0023] Of course, the above-mentioned embodiments are only for illustrating the technical concept and characteristics of the utility model, and the purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and it cannot limit the protection scope of the utility model. Any modification made according to the spirit and essence of the main technical scheme of the utility model should be covered within the protection scope of the utility model.
