Description

Technical Field

[0001] The present invention relates to the field of waste gas purification, and in particular to a UV photo-oxidation catalytic waste gas purifier and a purification method thereof. Background Art

[0002] Photocatalytic waste gas purification equipment adopts photocatalytic technology, using high-energy UV ultraviolet light beams and ozone to crack and oxidize the molecules of a large number of pungent, toxic and harmful organic waste gases produced by various production enterprises, so that the odorous substances are degraded into low molecular weight compounds, such as CO2, H2O and other substances, and then discharged.

In the present invention, it includes a purification box, and an air inlet pipe and an air outlet pipe are respectively provided on both sides of the purification box. The present invention provides a UV photocatalytic purification device and a purification method thereof. During operation, the exhaust gas enters the purification box through the air inlet pipe on the left side of the purification box, and the filter screen at the mouth of the air inlet pipe can filter the exhaust gas.

[0004] During the implementation of the above embodiment, the UV lamp on the connection frame is vibrated by the polarization motor and the polarization axis to dispel dust on the UV lamp. The above application document may damage the UV lamp when vibrating the UV lamp, which may require replacement of the lamp, thereby increasing costs. In addition, some equipment has difficulty in quickly cooling the UV lamp when cleaning it, resulting in low heat dissipation efficiency and possible damage to the lamp.

[0005] Finally: Since the exhaust gas contains flammable and explosive gases, it is difficult to detect flammable and explosive gases with existing technologies. In addition, some flammable and explosive gas detectors in existing technologies are usually fixed. When the flammable and explosive gas detector is damaged, it is difficult to quickly disassemble the flammable and explosive gas detector, which makes maintenance more troublesome.

[0055] The top of the catalytic box 1 is fixedly connected to an oxidation tank 33 via a connecting rod. The inner wall of the oxidation tank 33 is fixedly connected to a thermal insulation layer 34. The inner wall of the thermal insulation layer 34 is fixedly connected to an anti-corrosion layer 35.

The UV ultraviolet rays 11 irradiate the exhaust gas for more than 30 minutes at a certain light intensity, causing a strong oxidation effect on the exhaust gas, decomposing organic pollutants into harmless substances such as carbon dioxide and water. At this time, due to the delay control valve set inside the exhaust pipe 5 by the control terminal, the valve opens after 45 minutes, and the purified exhaust gas is then discharged through the fan 10;

[0066] Second, when the UV ultraviolet rays 11 are used up, the air pump 48 is started, and the gas is introduced through the air pump 48 to change the air pressure in the liquid storage tank 47, so that the disinfectant in the liquid storage tank 47 enters the water nozzle 468 through the water outlet pipes at both ends due to the pressure, and then the double-axis cylinder 41 is started, and the double-axis cylinder 41 drives the left and right first gear plates 42 to move, and the first gear plates 42 at both ends drive the two groups of first gears 43 to rotate in opposite directions, and the two groups of first gears 43 drive the two groups of second gears 44 to rotate through the connecting rod, and the two groups of second gears 44 drive the two groups of second gear plates 45 to perform alternating motion, and the two groups of second gear plates 45 drive the two groups of water nozzles 468 to perform staggered motion through the cooling mechanism 46, so that the UV ultraviolet rays 11 are sprayed more comprehensively, the spraying efficiency is improved, and the damage to the UV ultraviolet rays 11 caused by vibration cleaning is reduced.
