Smokeless treatment of range hood

The range hood is an essential electrical appliance in the kitchen, which can effectively deal with kitchen fumes and odors and improve indoor air quality. Although the range hood can effectively reduce the generation of lampblack, some lampblack will still escape, resulting in a pungent lampblack smell in the kitchen. Therefore, smokeless treatment has become an important function of range hood.

Smokeless treatment refers to a series of technical means to reduce the oil fume particles escaping into the kitchen air when the range hood smokes oil fume. Smokeless treatment technology mainly includes the following contents:

1. Wet smokeless treatment technology: Raising the humidity of kitchen air to over 80% through humidifier can make the oil fume easier to be captured. Inside the range hood, the oil fume is mixed with the sprayed water mist to form small water droplets, and then the oil fume particles are filtered out by the filter. This technology can effectively reduce the escape of oil fume, but it is easy to bring some health problems because of the need of water.

2. Secondary filtration smokeless treatment technology: A secondary filtration system is added to the traditional range hood, through which soot particles can be filtered out. This technology will not bring some health problems, but it needs to be modified inside the original range hood, which is not conducive to maintenance.

3. Smokeless treatment technology of activated carbon: installing an activated carbon filter screen at the outlet of the range hood can effectively remove soot particles and odor. This technology does not require high maintenance, but the activated carbon filter needs to be replaced regularly.

4. Ion-loaded smokeless treatment technology: the oil fume particles are negatively charged by the electric field, and then adsorbed by the positively charged collecting plate to collect the oil fume particles. This technology can effectively reduce the escape of lampblack, but it needs a higher technical threshold and higher cost.

Generally speaking, smokeless treatment technology can effectively reduce kitchen fumes and odors and improve indoor air quality. However, different technologies have different characteristics and application scope, so it is necessary to choose the appropriate technology according to the specific situation.
