Description

The invention relates to ventilation equipment, to devices designed to create an air stream, to clean it from particles and gases suspended in it, and can be used for ventilation and air purification in public premises and in production, for example, sawmills and furniture shops.

Known dust cleaner according to RU 1386808, class. F24F 7/06 of 10.20.1986, containing a chamber, air distribution nozzles with solid and liquid fillers, the last of which is located at the bottom of the chamber, and an air movement inducer, a removable fine filter located between the nozzles with solid and liquid fillers, the first of them is made in the form of annular cassettes with a sorbent located above the chamber with the formation of a vertical channel for the passage of cleaned air and having perforated side and end walls, the second in the form of a toroidal container open at the top awns with a solution of active reagents. The driver of air movement is made in the form of a fan mounted under the tank. The dust and gas cleaner additionally contains a movable platform, the camera is mounted on the latter, and the fan is equipped with rotary output nozzles.

The disadvantages of this dust cleaner are the complexity of the design and large dimensions.

Known filter module for cleaning air from toxic gaseous components, including a cylindrical body and a layer of sorbent located in it (RU 2172641 according to class B01D 53/02, B01D 53/04, B01D 53/86, B01D 35/01 from 11.24.2000 g .). This module contains an additional layer of a redox catalyst based on manganese and copper oxides, while the catalyst layer is made in the form of a hollow cylinder, and the sorbent layer absorbing hydrocarbons and other organic compounds is placed inside the catalytic layer and both layers are installed coaxially with the housing. The sorbent and catalyst layers are separated from each other by an inert layer, and the sorbent layer is made of activated carbon, while the catalyst layer is made of hopcalite. The filter module further comprises a forced heating unit for the cleaned air.

This filtering device is also complex in its execution and is expensive.

The objective of the invention is to provide a simpler and cheaper dust cleaner, which will significantly improve the process of high efficiency air purification containing suspended particles and gases.

The technical result when using the invention is to increase the efficiency of air purification and its healing.

The specified technical result is achieved by the fact that in a dust and gas purifier containing a housing, a fan, a filter device, a high-voltage power supply and corona electrodes, the filter device is made combined from a coarse filter and an activated carbon filter, and the corona electrodes are installed both in front of the coarse filter and in front of the activated carbon filter, moreover, the dust cleaner is equipped with a hopper for collecting suspended particles deposited into it from the coarse filter.

The drawing schematically shows a General view of the dust cleaner.

The dust cleaner consists of a housing (not shown), a fan 1, a filter device from a coarse filter 2 and a filter made of activated carbon 3. Corona electrodes 4 are installed in front of the filter 2 and filter 3. Under the coarse filter 2, a dust collecting bin 5 is installed . The dust and gas purifier is equipped with a high-voltage power supply unit (not shown).

Dust cleaner works as follows.

After the fan 1 is turned on, the contaminated air in rooms, for example, furniture shops, having passed the corona electrodes 4, enters (is pumped) into the coarse filter 2, where suspended particles (dust, sawdust, etc.), which enter the hopper 5, settle. Next, the air flow passes through the second corona electrodes 4 and in the filter 3 made of activated carbon, is finally cleaned. At the same time, an overall increase in the efficiency of air cleaning is achieved.
