Description

FILTER REGENERATION DEVICE

The utility model relates to devices for cleaning and regenerating filters, mainly designed for air purification from radioactive waste.

A device for cleaning filters is known, comprising a housing, inside of which there is a shaft with brushes rotating around its axis, while the lower part of the housing is allocated for dust collection (see ESTA Perfekte Absaugtechnic, Gesamtkatalog 1997, p. 8).

The disadvantage is that the filter element and the dust collection section are located in the same volume of the casing, which, when cleaning the air from radioactive waste, can lead to the accumulation of an unacceptable amount.

A known installation for the regeneration of filter elements containing a housing inside which is located in the upper part of the filter element is a rotating shaft with two nozzles for air supply, and the lower part is designed to collect dust (. ESTA Perfekte Absaugtechnic, Gesamtkatalog 1997, p. 8).

In this device, the filter element and the collected dust are also in the same volume.

The closest is a device containing a cylindrical housing, in the upper part of which there is a regeneration system through which the regenerating gas medium is passed, while the lower part of the housing is allocated for a dust collection device (see ESTA Perfekte Absaugtechnic, Gesamtkatalog 1997, p. 8).

The disadvantage is the combination in one volume of the place of regeneration of filter elements and the place of dust collection, which is unacceptable when working with radioactive substances, the need to disassemble the device to remove dust.

The objective of the proposed device is to simplify it, and to separate the place of regeneration of filter elements from the place of dust collection from the stream of gas to be cleaned (air).

The problem is solved in that the device for the regeneration of filter elements, comprising a housing for accommodating the filter element, a dust collection device, according to the proposed solution, the housing is equipped with stiffeners placed on the side ribs, with supports, the upper part of the housing is made in the form of a removable plate with clamping elements for providing the possibility of installing and removing the filter element and the hub for connecting to the regeneration system, and the lower part in the form of a base has an opening for connection to the inlet opening tiyu

dust collector, while the dust collector is removable with the possibility of a tight connection with the hole in the base.

The utility model is illustrated in the drawing, where:

1-case;

2-base;

3-plate with clamping elements;

4-filter element;

5-dust bag;

6 nipple for connection to a regeneration system.

The device comprises a housing 1, at the base of which a hole 2 is made. The upper part of the housing 1 is made in the form of a plate with clamping elements 3. To the base 2 is attached a drum 5.

The device operates as follows, the filter element 4 is installed inside the housing 1 on the base 2 and pressed hermetically to the base using the clamping elements 3. The dust collector 5 is mounted hermetically from the bottom to the base 2, and the dimensions of the inlet of the dust collector coincide with the dimensions of the holes on the base 2. Regenerating gas the medium is fed from above through the iguzer 6 plate 3. The regeneration system contains a system of distribution pipes and solenoid valves (not shown in the drawing). Having passed through the filter element 4, the regenerating gas medium together with the dust enters the dust collector 5, while the dust remains inside it. The dust collector material is selected depending on the type of dust and safety standards for working with certain types of dust. In particular, for a radioactive drink, polypropylene can be used as a dust collector material.
