Several factors to be considered in purchasing kitchen fume purifier.

Pay attention to the following factors when purchasing an oil fume purifier.

1. Novelty, advancement and applicability of technology. The novelty of technology includes not only the breakthrough of its purification principle, but also the advancement and rationality of the structure, including the composite composition between technologies. To make it advanced, improve purification efficiency, ensure stable operation and facilitate installation and maintenance. At the same time, we should also consider the applicability between the product and the market, that is, the diversity of specifications and varieties, suitable for exhaust volume and the size of kitchen stoves to meet different requirements.

2. The contradiction between technology and policy and law. The contradiction between technology and policy and law, and the resistance in product sales and application. The high-altitude emission policy of environmental protection department and the urban construction department's policy that pipelines are not allowed to cross the external wall and affect the beauty of the city have an impact on the application of technology. The high-altitude emission policy also conflicts with the private property law, so pipelines are not easy to cross the external wall of private houses, which can not be ignored in the study.

3. Product technology and economy. Economy includes product price, engineering cost, operation cost and maintenance cost. When studying, we should consider the purchasing power of the applicants, both high-end and low-end ones. Only by meeting the needs of different consumption levels can we finally achieve the goal of pollution control. Especially at this stage, there are many laid-off workers who are re-employed. Many laid-off workers rely on tens of thousands of dollars of compensation from enterprises to open small restaurants, so we should consider the economy of products.

4. The oil fume purification technology should be a hundred flowers blossom. Today's oil fume purification technologies have their own characteristics. As long as it meets the relevant national product standards and is approved by the inspection department designated by the state, it should be recommended. Any technology needs continuous improvement and perfection with certain market support, which is the need of enterprise survival and the necessary condition for technical improvement. Only by letting a hundred flowers blossom can we stimulate technological competition and revolution to the maximum extent, thus continuously promoting the healthy development of oil fume purification technology.

5, science and technology and economic development. The economic development of provinces and cities in China is unbalanced, and the economic benefits of catering industry units are different. If the price of the products provided is high, and the areas with poor economic development and units with poor economic benefits can't bear it, then the problem of oil smoke and waste gas pollution can only be partially solved but not controlled in a large area, which is not conducive to the ultimate goal of pollution control. Therefore, the purification technology is in full bloom, which makes the price of products different from that of high, middle and low schools, and makes areas with poor economic development and units with poor economic benefits have a choice. Only in this way can we effectively control the oil smoke pollution while developing the economy and achieve a win-win situation of economic and social benefits.

Generally speaking, to engage in environmental protection work, we should consider both the economic benefits of the enterprise itself and the social economic benefits; Not only environmental protection policies and regulations, but also relevant national policies and laws and regulations should be considered. All kinds of contradictions between them are often effectively solved by applying technology. A hundred flowers of suitable oil fume purification technologies are conducive to technological competition and technological revolution, to the formation of high, medium and low product prices, to the selection of pollutant discharge units, and ultimately to the realization of pollution control objectives and the steady development of social economy.
