A kind of oil fume purification device and the control method of the oil fume purification device

Abstract

The invention discloses a cooking fume purification device and a control method of the cooking fume purification device. The cooking fume purification device comprises an extractor hood body and a spraying device. The extractor hood body comprises a smoke gathering hood provided with an air inlet. A smoke guiding plate is arranged below the air inlet. and the spraying device comprises a spraying pipe, and the spraying pipe is provided with spraying holes capable of spraying liquid to the upper surface of the smoke guiding plate. Compared with the prior art, the cooking fume purification deviceand the control method have the advantages that through the arrangement of the spraying device, condensation, fire extinguishing and fire prevention are achieved, and the effects of safety and filtration are combined through one device; through the liquid spraying manner, the smoke guiding plate can be cooled in time, the surface temperature of the smoke guiding plate is reduced, when the cookingfume makes contact with the surface, rapid condensation is achieved, the purpose of purification is achieved, and when the fire behavior happens, the spraying speed can be increased, and accordinglythe functions of fire extinguishing and fire preventing are achieved.

Description

technical field [0001] The invention relates to the field of oil fume purification, in particular to an oil fume purification device and a control method for the oil fume purification device. Background technique [0002] Due to the unique characteristics of Chinese cooking, the amount of oil fume is very large. Long-term use will cause a large amount of oil to accumulate inside the range hood, resulting in performance degradation and poor effect of oil absorption. For catering units, oil fumes with large particle sizes will naturally settle. Adsorbed on the flue surface. As we all know, in some catering units, especially the kitchens of Chinese restaurants, high flames can often be seen. Once these flames are sucked into the air duct, it is easy to ignite the internal grease, causing fire and other hazards to people and property. Therefore, how to improve the filtering effect of oil fume and have fireproof performance is very important. [0003] At present, most of the el...

AI Technical Summary

Problems solved by technology

Although the short-term effect is remarkable, after a long time, the effect decays quickly, and the plate needs to be cleaned regularly. However, the plate is difficult to disassemble and clean, so every cleaning will waste a lot of manpower, physics and time costs.

[0004] In addition, oil fume purification equipment is usually installed at the end of the pipeline. When the oil fume in the pipeline comes over, it will be purified. In actual use, a lot of oil fume will remain on the wall of the pipeline. This method will leave a fire hazard.
