Description

The utility model relates to the field of protection of human respiratory organs from dust, aerosols, viruses.

As analogues of the proposed utility model, filters of respirators of the “Petal” type are known (see, for example, “Petal” (Light respirators) Petryanov I.V. et al. - M .: Nauka, 1984, pp. 58-59), containing several layers of passive filter elements. The disadvantages of such filters are the low efficiency of protection against aerosols and viruses, a small service life and the inability to regenerate the filter.

Also known are multilayer filters with a layer of sorbent material between the layers of filter elements (see, for example, patent RU 2101052), which can enhance the protection of respiratory organs, especially from aerosols, in comparison with simple disposable filters and respirators, but they have a low protection against viruses, low resource life and the inability to regenerate the filter.

As a prototype of the proposed utility model, we take a respirator filter containing layers of active elastic filter materials with an electrostatically charged filter element (see UA patent No. 50062 A, Bull. No. 10, 2002), which, due to the electrostatic charge of the filter element, can enhance protection respiratory organs, including viruses. The disadvantage of such filters is their short life due to the rapid loss of electrostatic charge of the filter element from contamination and the inability to regenerate the filter.

The technical task of the proposed utility model is to increase the protective properties of the filter and increase the resource of its effective operation.

The problem is solved in that in the filter of the respirator containing layers of filtering and sorption elements, electrically isolated layers of non-metallic conductive filtering and sorption elements are installed with the ability to connect to the source of electrical potentials.

As embodiments of the utility model, the conductive layers can be constantly connected to a source of electrical potentials, the conductive layers can be electrical isolated not only from the housing, but also between themselves and connected to different poles of the source of electrical potentials, the conductive layers can be installed with a gap between each other .

The installation of electrically isolated conductive filtering and sorption elements in the design with the possibility of connecting them to a source of electric potentials allows you to create and maintain the electrostatic field in the respirator filter for a long time, which increases the efficiency and resource of the filter’s effective operation, and also allows you to regenerate these filtering and sorption layers by passing through them current.

The option of constantly connecting the source of electric potentials to the conductive layers allows you to create and continuously maintain an electrostatic field that increases the efficiency of the filter.

The electrical isolation of the layers from the housing eliminates the drainage of electrostatic charges on the housing. The option of electrical isolation of the conductive layers between themselves and connecting them to different poles of the source of electric potentials allows you to create an electrostatic field between the layers and to delay pollution between the layers.

The option of installing conductive elements with a gap between each other allows you to install replaceable or regenerable conductive inserts in the gap to extend the life of the filter or install brushes in the gap with the ability to move for periodic manual cleaning of contaminants without disassembling the filter, or organize the removal of contaminant particles crumbling in the gap.

Implementation of a utility model.

As conductive filtering and sorption elements can be used, for example, layers of conductive non-metallic composite fibrous materials. The rest (for example, the first inlet and the last outlet) of the non-conductive filter layers can be made of conventional filtering materials, for example, from Petryanov's fabrics and others. All layers are installed in the filter housing with sealing along the perimeter, eliminating air leakage, bypassing the layers.

Plastic parts can be used as the electrical insulation of the conductive layers. To implement the ability to connect conductive layers to a source of electrical potentials, conductive layers have contacts. As contacts on the conductive layers can be installed, for example, metal terminals.

A small battery can serve as a source of electrical potentials. For the option of permanently connecting the source of electric potentials to the conductive layers, the source itself should be inside the filter or next to the filter.

The gap between the conductive layers can be created by installing plastic frames.

The possibility of installing interchangeable inserts in the gap can be provided by an opening housing.

The option of installing brushes in the gap with the ability to move allows you to clean the surface of the layers manually by moving the brushes.

Utility model work.

The proposed utility model works as follows. When air is inhaled, contaminants are retained in the filtering and sorption elements of the filter, and due to the creation of a long-term electrostatic field in the conductive elements from the source of electric potentials, the pollution is delayed more efficiently and for a longer time.

After severe contamination of the conductive elements, they are regenerated by passing an electric current through the contacts on them or the contaminants are removed using brushes.

Thus, the technical result is to increase the protective properties of the filter and increase the resource of its effective operation.
