Description

The utility model relates to techniques for cleaning dusty gases and can be used in the metallurgical, chemical and food industries, as well as in the building materials industry.

The closest in technical essence and the achieved effect is a filter for cleaning heterogeneous systems, consisting of a housing with a filter baffle, dividing it into chambers of contaminated and purified media, pipes for input and output of a medium, a pipe for output of concentrate, traverses and flexible inserts, regenerating partitions [RF patent No. 2282482, Cl. B01D 46/10, 2006].

The disadvantage of the prototype is the insufficiently high efficiency of the process of regenerating the filter septum from sediment during prolonged operation of the filter and high concentrations of the dispersed phase.

The technical task of the utility model is to increase the efficiency of cleaning the filter membrane from sediment, increasing the reliability and performance of the filter.

The technical task of the utility model is solved by the fact that in the filter for cleaning heterogeneous systems, which includes a housing with a filter baffle separating it into chambers of contaminated and purified media, pipes for entering contaminated and output of purified media, pipes for concentrate output, crossheads and flexible inserts, the regenerating partition, new is that the regenerating partition is made in the form of a turbulizing surface formed by transverse slats 40-60 mm high and a pitch of 60-80 mm, rigidly installed at an angle of 135-160 ° to the direction of flow of the polluted medium.

The technical result of the utility model is to increase the efficiency of cleaning the filter membrane from sediment, increasing the reliability of the filter and its performance.

Figure 1 - shows a filter for cleaning heterogeneous systems at the time of filtering, section; figure 2 - filter for cleaning heterogeneous systems at the time of regeneration.

The filter (figure 1, 2) contains a housing 1, a filter baffle 2, dividing the housing into chambers of contaminated 3 and purified media 4, a nozzle for introducing a dispersed medium 5, a regenerating baffle 6 made in the form of a turbulizing surface, the transverse bars 7 installed at an angle of 130 160 °, traverses 8, flexible inserts 9, outlet pipe for the purified medium 10, pipe for the outlet of the concentrate 11.

The filter for cleaning heterogeneous systems works as follows.

A heterogeneous medium under the influence of a differential pressure enters through the nozzle 5 into the chamber of the contaminated medium 3. The dispersed medium, passing through the filter baffle 2, is cleaned of impurities and enters the chamber of the purified medium 4 and then is discharged from the filter through the nozzle 10. As the deposition occurs on the outer surface of the filter baffle, a layer of sediment accumulates, and the hydraulic resistance of the filter increases and there is a need for its regeneration. At the time of regeneration, the regenerating partition 6 by means of a traverse 8 and flexible inserts 9 is lowered to the lower position (figure 2). In this case, due to the complex turbulizing shape of the regenerating partition 6 formed by transverse plates 7 located at an angle of 135-160 ° to the direction of movement of the contaminated medium, an increase in local alternating flow rates occurs and a tangential driving force arises, which helps to remove sediment from the surface of the filter partition. The sediment layer removed from the filter baffle with a part of the heterogeneous medium is removed through the outlet pipe, concentrate 11 into the pre-cleaner.

The proposed filter for cleaning heterogeneous systems provides effective regeneration of the filter membrane, high reliability.

allows you to:

- increase the efficiency of the process of cleaning heterogeneous systems;

- increase the reliability of the filter;

- increase the efficiency of the process of cleaning contaminated heterogeneous environments due to the effective regeneration of the filter septum;

- intensification of the cleaning process;

- continuous cleaning process.
