Description

Long-diameter low-light resonance exhaust gas treatment device

technical field

The invention belongs to the technical field of waste gas treatment, in particular to a long-diameter low-light resonant waste gas treatment device.

Background technique

With the current development of industry and commerce and the enhancement of environmental protection awareness, the deteriorating living environment has attracted the general attention of the public and the industry. Among them, due to the vigorous development of industry, air pollution spreads rapidly, and harmful exhaust gas spreads over a large area. The pollutants directly harm people's health through the respiratory system. In response to this development trend, various technologies and equipment related to environmental protection engineering have been continuously developed. The purification treatment of industrial waste gas is one of the most important issues faced in many environmental protection cases.

At present, the industry mainly adopts activated carbon method, condensation method, spray absorption method, etc. The existing activated carbon exhaust gas adsorption equipment is complicated, and the adsorbent is easy to be saturated, requiring frequent replacement or high cost of regeneration exhaust gas treatment; The effect is not ideal, it can only remove part of the organic matter and particulate matter in the exhaust gas, and it is difficult to meet the emission standards. Therefore, it is desired to provide an exhaust gas treatment device with good purification effect.

The patent document with the notification number CN204816178U discloses an exhaust gas treatment device, which includes a reflective shell, a microwave electrodeless lamp arranged inside the reflective shell, a microwave converter set outside the reflective shell, and connected to the microwave converter through a microwave transmission line. The microwave generator, the reflective shell is provided with an inlet for exhaust gas on the side close to its one end, and the reflective shell is provided with an air outlet on the side close to the other end, and the microwave converter is arranged on the reflective shell The end near the air inlet is electrically connected with the microwave electrodeless lamp tube. The waste gas treatment device generates continuous-wavelength microwaves through the microwave generator and transmits them to the microwave converter. A part of the microwaves can excite the microwave electrodeless lamp to emit high-intensity ultraviolet rays, and the other part of the microwaves and the high-intensity ultraviolet rays are reflected back and forth in the reflective shell for multiple times. , and react with the exhaust gas in the reflection tube to obtain a large amount of ozone and free hydroxyl groups, which strongly destroy and oxidize and reduce the exhaust gas molecules, thereby obtaining clean gas.

The patent document of notification number CN206229137U discloses a low-light resonant exhaust gas processor, including a body, which is provided with an exhaust gas reaction chamber, and the body is provided with an inlet port and an air outlet port for exhaust gas to enter and exit the exhaust gas reaction chamber. There is a microwave generator and an electrodeless ultraviolet lamp assembly electrically connected to the microwave generator. The side of the waste gas reaction chamber near the gas outlet is provided with a plurality of vertically arranged ultraviolet lamps with electrodes, and a first filter is provided at the gas outlet. It can strongly destroy and oxidize exhaust gas molecules by generating a large amount of ozone and free hydroxyl groups generated in the exhaust gas reaction chamber. When the exhaust gas molecules after oxidation and reduction are discharged from the exhaust gas reaction chamber, they can also be further oxidized by ultraviolet rays, and finally in the outlet The dust particles in the exhaust gas molecules are removed through the filter at the port.

However, due to its short path, that is, the purification time of exhaust gas is relatively short, resulting in part of the exhaust gas being discharged without being completely purified. Therefore, it is necessary to extend the purification time of exhaust gas, and at the same time strengthen the intensity of redox to improve the purification rate.

Moreover, during the use of the ultraviolet lamp, the user will add a planar photocatalyst plate. The existing photocatalyst plate has the following disadvantages:

1. Since the ultraviolet rays irradiated by the lamp tube are diffusive, and the photocatalyst plate is a planar structure, the middle part of the photocatalyst plate is close to the lamp tube, and its edge is far away from the lamp tube, so the light intensity obtained in the middle part is much greater than that in the edge part, resulting in the photocatalyst plate The air purification capacity in the central part is much larger than that in the edge part, and the distribution is uneven.

2. The exhaust gas flows along one side of the photocatalyst plate, so that the concentration of ozone and hydroxyl on one side of the photocatalyst plate is lower than that on the other side, resulting in low purification efficiency.

Preferably, the lamp holder is provided with a plugboard, and the inner surface of the housing is provided with a slot, and the plugboard is detachably connected to the slot.

Compared with the prior art, the long-diameter low-light resonance exhaust gas treatment device adopting the above technical solution has the following beneficial effects:

1. The far-beam end of the photocatalyst plate is set opposite to the ultraviolet lamp tube, and the near-beam end is located on both sides of the ultraviolet lamp tube. The light of the ultraviolet lamp can be more evenly irradiated on the photocatalyst plate. The irradiation intensity of ultraviolet light obtained at the end of the far beam is relatively close (and for a separate flat photocatalyst plate, because the middle part is close to the ultraviolet lamp tube, the illumination intensity is greater than that at the edge), so the ozone and hydroxyl groups produced on the photocatalyst plate are relatively uniform and The concentration is also higher, and the purification effect on exhaust gas is more obvious.

Take away together with the hydroxyl group, unreacted ozone and hydroxyl group will no longer remain on both sides of the photocatalyst plate, and the ozone and hydroxyl group will be fully utilized to effectively improve the efficiency of exhaust gas purification.

4. The light frame and the plate frame are arranged alternately to form an S-shaped airflow channel for the exhaust gas to pass through, so that the exhaust gas flows back and forth from the shell. The purification time and path of the exhaust gas in the same space are longer, and the purification efficiency is higher and more complete.

5. The microwave generator generates microwaves with continuous wavelengths. Part of the microwave excites the ultraviolet lamp to emit high-intensity ultraviolet rays. The high-intensity ultraviolet rays generated together with the other part of microwaves go back and forth in the exhaust gas reaction chamber through multiple reflections and resonances to obtain a large amount of ozone and free hydroxyl groups. , a large amount of ozone and free hydroxyl groups can strongly destroy and oxidize and reduce exhaust gas molecules, so as to obtain clean gas, and then achieve the purpose of organic waste gas treatment.
