Abstract

The invention relates to filters for the ionic purification of a gaseous medium passing through a pipeline, and can be used in the gas, chemical and other sectors of the industry. Its use makes it possible to improve the quality of cleaning the environment and reduce sprinkling. A device for cleaning a gaseous medium, comprising a housing in the form of a main pipeline, is provided with packages in the form of three elastic chrome-plated polished plates of various lengths. The shorter plates are made with elliptical holes and are supported on a large solid plate, made with a perforated curved edge. Capillary tubes are installed between the housing and the larger plate, the lower ends of which are lowered into the bath of the inlet chamber and equipped with jets. 5 il.

Description

The invention relates to filters for the fine purification of gaseous medium passing through a pipeline, and can be used in the gas, chemical and other industries.

The purpose of the invention is to improve the quality of cleaning the environment and reduce sprinkling.

Figure 1 shows the device, side view} in figure 2 is the same, top view; on fig.Z - section aa in figure 1 $ on figure 4 - plate pack, unfolded position; figure 5 - the device, in isometric.

The device for cleaning the gaseous medium consists of a body 1, made in the form of a length of the main pipeline, a slit type 2 shutter for changing filter inserts 3, made in the form of several lattice frame blocks, installed successively one after another in U-shaped guides 4, passing along the axis of the pipeline, segments 5, located on opposite sides of the axis of the filter inserts 3 in the ends of the pipeline segment. At the exit from the filter insert, the chamber contains bags of three thin elastic, chrome-plated polished plates 6, two of which, the smallest, are perforated with elliptical holes and have different height sides. Third - the largest plate - solid with a curved perforated

edge upstairs. At the bottom, all plates are rigidly bonded, and at the top, two perforated plates abut in the unfolded state against the edge of the solid plate. Under the filter inserts 3 along the pipeline axis between the guides 4 and the body 1 vertically, there is a sheet 7, which divides the bath into two parts, the right one with a clear wetting medium and the left one with a contaminated liquid, and the contaminated liquid after the separator again enters right half of the bath. At the bottom of the sheet 7 are placed the jets 8, metering the flow of the wetting fluid and located at the ends of the capillary tubes 9 placed between the large plate of the package 6 and the housing 1, the wetting fluid over them on the filter inserts 3 rises up and expires on the top of polished plates having elliptical holes 10.

The device works as follows.

The filtered gaseous medium, approaching the filter housing 1 and meeting the segment 5, partially changes its direction and increases the speed. The gas flow from the right half of the filter passes to the left through the filter inserts 3 and is cleaned of large suspended particles. In the left part of the filter, the gaseous stream passes through the elliptical orifices 10 of the first plate 6 and, in contact with the perforated surface of the second plate 6, is freed from the remaining solid particles. The passage further through the ellipse holes 10 of the second plate, the gas flow meets the smooth, non-perforated surface of the third plate 6 of the stack and, once again in contact with it, leaves suspended solids on the wetted surface. Most of the gas flow passes through the elliptical orifices of the first and second plate 6, and since the space between the first and second plates at the outlet of the package 6 is sharply narrowed due to the difference in height between the sides of the first and second plates 6 of the package, it is forced perforated plate 6 pa-. chum, thereby purifying the medium to be filtered is performed more finely.

The fluid from the bath, located on the right side of the filter, continuously enters the upper part of the stack of polished plates 6 through the ca-. pill tubules 9.

The ability to place any number of filtering inserts and bags allows you to increase the area of filtering and wetted surfaces indefinitely.

When a filtering mesh breaks through, the first two perforated plates of the bag collapse, mutually overlapping the ellipse holes, and a characteristic medium whistle appears, signaling that the filtering mesh breaks through.

The presence of nozzles on capillary tubes leads to the creation of a simple and reliable system for wetting the surface with a constant self-cleaning of the surfaces of the plates of the bag.

Placing the device in a housing, which is directly part of the main pipeline, allows gas to be cleaned at any large pressures, up to the pipeline’s design pressure, for the purpose of using pulsed gas to clean gas in underground storage facilities.
