(54) FILTER FOR GAS CLEANING

one

The invention relates to the design of filters used for the purification of gases from solids, and can be used in the chemical, pharmaceutical, metallurgical and other industries.

A filter for cleaning gases is known, comprising a housing with a flange and having chambers of purified and dusty gases separated from one another by a partition. Filtering elements and scrapers are placed on the shaft in the chamber of dusty gas. Filter elements are made in the form of a disk with a central hole through which the shaft passes with scrapers mounted on it. Filter discs are fitted with collets located along the entire perimeter of the discs, and they are assembled into a single set with end clamping clamps and clamping bolts. The flue gas inlet is located on one of the end plates, and the dust outlet is on the other end plate 1).

The disadvantages of the known filter are low productivity and low unit power of the filter.

The aim of the invention is to increase the filter performance by increasing the period of continuous operation and reducing the time for removal and installation of the filter, as well as an increase in its unit power.

This goal is achieved by the fact that in a gas purification filter comprising a housing with a flange including separated

10 one from another by a partition of a chamber of purified and dusty gases, in the last of which filter elements and scrapers are installed on the shaft, the filter elements are made with a vertical groove and a vent hole on

15 one of the ends, and the partition - in the form of adjacent to one another plates with a hole coinciding with the hole of the filter element, while the plates are mounted on the flange of the housing and attached

20 to the filter element.

Moreover, the filter elements can be made in the form of a disk.

In addition, the filter elements can be made in the form of a rectangle.

FIG. 1 shows a filter, a longitudinal section; in fig. 2 is a section A-A in FIG. one; in fig. 3 - option filter option; in fig. 4 is a section BB in FIG. 3

The filter housing 1 is closed by a cover 2. Inside the housing 1, filter elements are located. Elements 3 and scrapers 4 are detachably fixed to shaft 5 by means of a key 6. Filter element 3 has a frame 7, two filter screens 8 located at a distance from each other and fixed on the frame 7 by means of rails 9. Plates 10 of adjacent filtering elements 3 adjoin each other and form a partition dividing the inner space of the housing 1 into two chambers - the upper chamber II of the cleaned gas and the lower, new chamber 12 of the dusty gas. The plates 10 are mounted on the flange 13. In the plates 10 and filter elements 3, holes 14 are made that connect the internal cavity of the filter elements 3 to the clean gas chamber 1 1. The filter elements 3 are made with a vertical groove 15. All filter elements 3 are stolled, in a single package 16. The clean gas chamber 11 is provided with a choke 17 for outputting the cleaned gas. The fitting 18 serves to inject the dusty gas into the chamber 12.

Fp.i / grooving elements 3 can be made rectangular in shape (Fig. I II 2) and in the form of disks (Fig. 3 and 4). The plates 10, respectively, are made in the form of rectangles (Fig. 1, p. 2) or they have a ziyrn shape (Fig. 3 and 4). The flange 13 can be made on the inner surface of the housing (Fig. 3 and 4) or along the perimeter of the upper edge. mk case (Fig. I and 2).

The filter works as follows. Dust-laden gas through shtucer 18 is placed in chamber 12 and passes through filter elements 3. When passing through filter elements, dust particles are deposited on filter grids 8, and the purified gas enters the internal cavity of filter elements and through holes 14 - into chamber 11 .

Scrapers 4, rotating, cut off the dust deposited on the filter grids 8, remaining in

l layer of dust, which is a filter layer,

Dust, cut off from the filter sinter, settles down and is removed from the filter through a special valve (not shown).

The proposed filter design allows the scrapers to be installed exactly in the desired position, take 1 filter elements and shorten the time for dismantling and installing the filter, i.e., reduce the unproductive time spent, which ultimately leads to an increase in filter performance.

In addition, the overall dimensions of the filter have little effect on the installation accuracy of filter elements, which makes it possible to increase the unit power of the filter.
