Description

 The invention relates to a device for cleaning liquids containing suspended and organic substances, heavy metal ions and can be used in wastewater and natural water treatment technologies of electronic industry enterprises, instrument-making, machine-building, chemical and other industries.

 Known cartridge filter containing a housing with nozzles for supplying a cleaned liquid and drainage of the filtrate and washing liquid, filter cartridges located in the housing, made in the form of a perforated frame with a wire spiral placed on it.

 The disadvantages of the cartridge filter are the low productivity and efficiency of the extraction of organic contaminants and heavy metal ions from the treated water due to the lack of a uniform distribution of the cleaned stream in the volume of the filter load and filter material in the cartridge, as well as sufficient adsorption properties of the materials used. In addition, the supply of the liquid to be cleaned to the lower part of the cartridge will increase the hydraulic resistance of the lower layers of the filter material when they are contaminated with extractable substances, and thereby create conditions for the irrational use of the upper layers of the filter material, reducing the performance and efficiency of each cartridge and filter as a whole.

 Obvious in the known filter is a complex air distribution and drainage system that complicate the hydraulic conditions of the filter and its operation, significantly reducing the performance and efficiency of the cartridge filter.

 The purpose of the invention is to increase the degree of purification and filter performance by creating optimal conditions for carrying out the filtration process and the use of highly sorption filter materials.

 The goal is achieved in that in a filter for cleaning liquid, containing a housing with nozzles for supplying cleaned and washing liquid, drainage of the filtrate and the washed solution, and vertical filtering elements placed in the housing, the elements are made of rods located in the corners of an equilateral pentagon and covered with layers of activated fabric, muffled in the lower part, fixed to the partition in the upper part of the housing, dividing it into chambers of contaminated and purified liquid.

 In FIG. 1 shows a diagram of a longitudinal section of a filter; in FIG. 2 is a section AA in FIG. one; in FIG. 3 fragment of a longitudinal section of the filter module; in FIG. 4 section BB in FIG. 3.

 The filter consists of a detachable housing 1 having nozzles for supplying the cleaned 2 and washing 3 fluids, the drain of the filter 4, the washing solution 5, the filter elements 6, containing the core frame 7, covered with an activated fabric 8 and installed in a microfiltration porous cylinder 9 with a plug 10 in the lower part, and in the upper one fixed on the partition 11, dividing the filter into chambers contaminated 12 and purified 13 liquids.

 The filter works as follows.

 The liquid to be cleaned through the nozzle 2 located in the lower part of the housing 1 enters the chamber of the contaminated liquid 12, from where, passing through the lateral surface of the microfiltration porous cylinder 9 with a plug 10, it is cleaned of finely dispersed suspended substances trapped on the pores of the material used. Then, the liquid is subjected to sorption purification by filtering through activated tissue 8 located on the rods of the frame 7 located in the corners of an equilateral pentagon and installed in the microfiltration cylinder, providing optimal conditions for the liquid to be cleaned through the filter cloth and the rigidity of the proposed design of the filter module. As a result of sorption purification, organic substances and heavy metal ions are extracted from the liquid being purified. The liquid thus purified enters the central part of the filter element 6, which is fixed on the partition 11 with the upper part, then into the chamber of the purified liquid 13, and then, through the outlet of the filtrate 4, is discharged outside the filtrate.

 During the cleaning process, the filter material is contaminated and needs to be regenerated.

 The regeneration of the filter material is provided by a five percent acid solution, followed by washing with a purified liquid. The wash water and acid solution are supplied through the pipe 3, and the drain through the pipe 5. The passage of regeneration solutions from the central part to the periphery of the side surface of the filter element ensures that the impurities are washed away on the filter cloth and microfiltration surface, thereby restoring its filtering ability, ensuring long-term and reliable filtrate operation with high efficiency and productivity. Regeneration solutions are cleaned and reused to restore the sorption properties of the material used.
