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 cleaned 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, a regenerating partition, a new one is that a coaxial diffuser and an outlet section of a tube for supplying compressed air are installed in the inlet port of the contaminated medium, the inlet part of the tube is installed under 15-30 ° gap to the axis of the inlet pipe of the contaminated medium.

The technical result of the utility model is to increase the efficiency of cleaning the filter membrane from sediment, increase the flow rate of the dispersed medium in the apparatus by 1.5 times, increase the reliability of the filter and its performance.

Figure 1 - shows a filter for cleaning heterogeneous systems, section; figure 2 - node A, section.

The filter (Fig. 1) comprises 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, traverses 7, flexible inserts 8, an outlet pipe for a purified medium 9, a nozzle for the output of the concentrate 10, the outlet section of the tube for supplying compressed air 11 to the input port of the contaminated medium 5, and the diffuser 12 are mounted coaxially in the input port of the contaminated medium, the inlet part of the tube is installed at an angle of 15-30 ° to the axis of the input port of the contaminated medium.

The filter for cleaning heterogeneous systems works as follows.

A heterogeneous medium under the influence of a pressure drop 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 9. 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 7 and flexible inserts 8 is lowered to the lower position (figure 1). At the same time, 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 wall. For a more complete cleaning of the filter baffle from the trapped sludge required at high concentrations of the dispersed phase, compressed air is supplied simultaneously with the regenerating baffle being lowered through the tube 11 into the diffuser 12 installed coaxially in the inlet of the dispersed medium inlet. The sediment layer removed from the filter baffle with a part of the heterogeneous medium is removed through the outlet pipe, concentrate 10, into the pre-cleaner.

The proposed filter for cleaning heterogeneous systems provides effective regeneration of the filter membrane, an increase in the dispersed medium flow rate in the apparatus by 1.5 times, and high operational 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.
