First, the development history of fume purification equipment technology
Under normal circumstances, almost all of the high-tech is introduced to China from the beginning of foreign countries, and then rooted in China to grow and develop. The fume purification technology is an exception. The development and production of domestic fume purification equipment can be borrowed without foreign advanced technology, and almost all kinds of soot purification technologies are developed by the local. The reason is that the unique cooking method of Chinese cooking leads to completely different soot exhaust gas from Western cooking. The demand for soot purification technology in western developed countries is far less than that in China. The increasing awareness of environmental protection among Chinese people is the new technology of fume purification. Strong biocide.
In the mid-1960s, Hong Kong had begun to use soot purification equipment. Since then, some parts of the country have begun to develop and use soot purification equipment, which was mainly used in simple ways such as mechanical grille and water spray. By the end of the 1980s, the technology of water hood and water curtain machine gradually matured and was widely used in high-end occasions. These technologies have a good effect on kitchen fire and oil fume degreasing, basically can do the kitchen after long-term work. There is no serious greasy pollution in the soot discharge. Until the early 1990s, the soot purification technology basically stayed in the aforementioned mechanical purification method, which can effectively remove the oil droplets in the soot, and at the same time reduce the temperature of the exhaust fumes, but can not really remove the smoke components in the soot. Therefore, the purified soot is still observed by the naked eye during the peak period.
In the mid-1990s, in the relatively economically developed areas of China, some large enterprises in the catering industry began to install the electrostatic fume purifiers of the fume purification equipment and began to enter the market. At this time, the electrostatic fume purifier technology is very immature and in the experimental stage. The main technology comes from the conventional industrial electrostatic cleaning equipment. It can be said that every engineering example in this period is the equipment manufacturer's laboratory, and one project is installed. It takes almost a few months to complete the commissioning, and the service life of the equipment often does not exceed two years. Since the equipment installation at this stage belongs to the user's spontaneous purchase and installation, and the equipment is extremely expensive (the price of the three burners matching equipment is roughly RMB 60-80,000), there are few users and no real market is formed.
At the end of the 20th century, the State Environmental Protection Administration issued a trial standard to limit the emission of soot from the catering industry. In 2001, the official national standard of the People's Republic of China - Ambient Air Quality Standard GB 18483-2001 "Fume Emission Standards for Catering Industry" was issued. All catering companies must install fume purification equipment. The market prospects of fume purification equipment have suddenly become clear, and many companies and investors have entered the development and production of fume purification equipment. In just a few years, domestic fume purification equipment manufacturers have mushroomed. The market is full of various types of soot purification equipment of various brands. Among all kinds of fume purification equipment, electrostatic fume purification equipment has high technical content, and it is also a device that can completely eliminate the pollution of soot. In just a few years, electrostatic fume purification technology has also been faster. Development, there are emergent electrostatic fume purification equipment with mature technology, good long-term product stability and convenient cleaning.
Second, the good and the bad, the mixed fish and purifier market
The fume purifier market is very immature, all kinds of inferior products are flooding, and many companies that do not have minimum technology at all have joined the competition in this market. Moreover, because they have no technical input at all, the equipment is shoddy and the "cost" is extremely low. With "market competitiveness", the main reason is that users lack understanding of soot purification equipment, and believe that purification equipment can not create production value, can be omitted as much as possible, can not be omitted, try to buy the cheapest, so all kinds of fake and shoddy Products can only be popular. On the contrary, many users who suffer from complaints from neighbors need high-quality soot purifiers but have serious doubts about the performance of high-quality soot purifiers.
Typical performance of the following inferior soot purification equipment:
1. "Purification equipment" has no effect at all, but instead increases the exhaust resistance, resulting in poor ventilation. Finally, it has to be hollowed out and turned into a poor quality pipe.
2. It just had a little effect when it was installed. After a few weeks, the situation changed significantly. Some serious obstructions caused difficulty in exhausting smoke. The air quality in the kitchen deteriorated, and some completely lost their function and became a display.
3. The equipment work is extremely unstable, sometimes the effect is acceptable, sometimes the smoke is rolling, and abnormal phenomena often occur. From time to time, you can hear the sound of the discharge of the "噼啪", and even cause a fire.
4. In addition to the general effect of smoke removal, on the one hand continue to smoke, on the other hand, the ability to "contaminate" around the discharge port is very strong (if the surface of the building is not equipped with inferior electrostatic fume purifiers, it will not produce black pollution). After a few days of use, the walls and objects around the discharge port were severely blackened, affecting the surrounding environment. Inferior purifiers also have a lot of bad performance, and any performance may bring trouble to the restaurant.
