In this era of advocating environmental protection and energy saving, people engaged in catering industry should consider the problem of buying enough oil fume purifiers. However, due to the diversity of brands of oil fume purifiers in the market, some people don't know how to choose. Here, Hong Ying points out a method for everyone, that is, first understand the characteristics of high-performance oil fume purifiers: 1. Long-term stable work, low failure rate. The working principle of oil fume purification equipment is not complicated, and the principle of high voltage static electricity is generally adopted in the market, but how to work stably for a long time in the environment of high temperature, high humidity, power grid turbulence and polluted air is the key technology. The performance difference between high-end and low-end products is worse than that between vans and Mercedes-Benz. The purpose of installing oil fume purification equipment by customers is to avoid trouble, not to make trouble. If the equipment failure rate is high, frequent equipment maintenance will cause a lot of trouble for normal business even if the after-sales service of manufacturers can keep up. So the first point is to consider the stability of the machine and the after-sales service of the manufacturer. 2. The oil fume can't be observed by naked eyes at high altitude. The purification efficiency of high-performance oil fume purifier is generally above 91%. Even in the peak period of restaurant work, ordinary people can't observe the existence of smoke in the exhaust gas with their naked eyes after being treated by such purifier. For the high-demand oil fume purification project, as long as the existence of oil fume can be observed, it can be concluded that the project has failed, no matter how many reasonable explanations the equipment manufacturers have, it is futile, because your neighbors will completely ignore the complaints of the manufacturers, and they will complain as long as they see the smoke. Hongying oil fume purifier Lanzhichun series is an electrostatic oil fume purifier specially developed for the pursuit of visual smokeless, which can completely help customers achieve the visual effect, especially suitable for restaurants without smoke wells or high-altitude emission conditions. 3. The discharge port and the surrounding environment will not be polluted after long-term operation. Some oil fume purification equipment has quite good purification effect, but due to the lack of negative ion neutralization function, the concentration of negative ions in the exhaust gas is too high, which will accumulate a lot of charges on the surface of the object at the discharge port, thus adsorbing pollutants and causing the surface of buildings around the discharge port to become black, causing serious visual pollution. 4. The cleaning cycle of the oil fume purifier is long, and the cleaning and maintenance time is fast. Different kinds of equipment have different cleaning cycles and cleaning methods. Under normal circumstances, normal cleaning and maintenance will not affect the normal business of the restaurant, but the length of maintenance cycle and the labor intensity and trouble of each maintenance will be an important criterion for customers to choose the purifier. The cleaning cycle with an interval of more than one month and the longest cleaning and maintenance time of no more than one hour each time are the technical standards that ordinary oil fume purification equipment can hardly meet, while high-performance oil fume purification equipment can basically be cleaned once every two months, and only takes about half an hour each time.
