A, the classification of lampblack purifier
1, filter oil fume purifier
Filter-type fume purifier mainly includes two categories: mechanical collision and adsorption filtration; At present, the method of removing dirty oil from oil fume by oil screen filtration is still used in domestic range hoods. The particles in the oil fume are only a few microns, which are in a gelatinous floating state in the air and will be bypassed when encountering the anchor net. Only the soot particles with large inertia will hit the anchor net, and the purification rate is very low. After the oil filter is stopped, the wind resistance is large, the cleaning is difficult, the technology is backward, and it is easy to cause a fire. The Environmental Protection Department has banned the use of anchor net filtration in catering kitchens. Pure mechanical collision is mainly used for pretreatment. It is usually used in combination with other technologies. In practical application, pure filtration technology is affected by many factors, such as the flammability of filter materials, limited adsorption capacity, poor reusability and large resistance. The filtration technology can meet that requirement of purification index,
Dong Can can't have several excellent characteristics at the same time, and its market application is very small. 2, mechanical separation purifier
The oil fume airflow enters the drum purifier from the tangential direction, and the oil fume particles are separated from the airflow under the action of centrifugal force, and the polluted fm gathers on the drum wall and flows downwards for centralized collection and treatment. The mechanical separation purifier has the advantages of low investment, low operating cost, high purification rate, up to standard and convenient maintenance and management. The main problem is the large resistance, so there are specific requirements for the exhaust fan, which is bulky.
3. Water mist fume purifier
Also known as wet fume purifier. Wet technology is a mature technology, that is to say, daily maintenance is relatively simple, there is no fire hazard, and it also has the function of removing oil smoke and odor. This method is especially suitable for removing large oil particles: however, when working outdoors in northern winter, there is a problem of equipment antifreeze.
Second, the composition of lampblack purifier
1, dual-frequency high-voltage ion generator
High-voltage ion generators all adopt the principle of dual-frequency control, which is not the general single-frequency control mode (ordinary oil fume purifier). This will improve the stability of the product.
2. Adsorption plate spacing
The distance between the low-pressure adsorption plates determines the effective adsorption area of the product and directly affects the purification efficiency of the oil fume purifier. The distance between the plates is between 9 mm and 20 mm. ..
The purification efficiency is greatly improved. 3. Standard design
Modular design is adopted, which is more humanized and can easily combine the air volume required by users.
