Abstract

The invention relates to installations for the reagent purification of liquids, can be used in the technique of water purification in the chemical, engineering industry and allows to increase the efficiency of water purification. The installation consists of an inlet device 1, located in the upper part of the mixer 2, to which, from the inner side, there is a gravel flocking chamber (CWC) 3, resting in its lower part on the grate 4 serving. both to maintain the load and to distribute the eye evenly (L S ISD

Description

splash water The overflow device 5 / in the form of a toothed weir ensures the constancy of flow along the length of the CWC. Under the CWC, blocks 6 are located, consisting of obliquely installed (50-60 °) tubular elements (TEs) 7 with a diameter d, whose axes in cross section are placed through 0.75 d horizontally and through d vertically, each element in its bottom to the partition 22 has an opening for the inlet of the suspension, l

whose area is equal to the cross section of the element, and open end parts 9 (top) and 10 (bottom), respectively, for the release of pure water and sediment. The invention allows improving the quality of water purification by supplying the installation with a quick filter 18 placed under the TE blocks 6 and a mixer 16 for deodorizing water installed in the chamber 15 for collecting clarified water. 1 z.p., L-ly, 3 ill.

The invention relates to devices designed for a reagent liquid binder, and can be used in the technique of water purification, in the chemical, engineering and other industries,

The aim of the invention is to increase the cleaning efficiency by increasing the volumetric utilization ratio of the plant.

FIG. 1 shows the installation, cross section; in fig. 2 — node I in FIG. one; in fig. 3 shows section A-A in FIG. 2

The installation consists of an inlet 1 for supplying raw water and reagents; mixer 2; a gravel chamber 3 flocculation resting on the grate 4 below; overflow device 5; a sump in the form of blocks 6 consisting of obliquely installed tubular elements 7 with a diameter o, the axes of which are in cross section are placed through 0.75d horizontally and cj vertically, each element 7 having an opening 8 for inlet of the suspension, the area of which is equal to the transverse the cross section of element 7, and the open end parts 9 and 10, respectively, for the release of pure water and sediment ,; the sediment part 11 for isolating and sliding the sediment from the initial suspension before it enters the holes 8 of the tubular elements 7; sediment part 12 for sediment slipping from tubular elements 7; devices 13 and 14

to remove sediment; located between the blocks 6 of the chamber 15 of the clarified water, the height of which is an additional mixer 16 for

mixing the clarified water with a deodorizing agent introduced through the feeder 17, in front of the single-layer rapid filter 18 s located under the tubular blocks 6

cap drainage 19 and perforated by-pass pipe 20. Fastening the tubular elements 7 into blocks 6 and sealing zones 11, 12 and 15 between them is achieved by means of partitions 21 and 22 with sealable openings. For emptying the flocculation chamber 3, a conduit 23 serves which can be used to introduce additional coagulum or

flocta nta in front of the flocculation chamber.

The installation works as follows.

Purified water together with the reagents through the inlet device 1 enters the mixer 2, where for a specified time thorough and uniform mixing of the components takes place. From mixer 2 through

. (The grate 4 mixture enters the gravel chamber 3 of the flora formation with expanded clay loading, where the flooding process takes place, after which the suspension device 5 is poured into the interracing-space of the elements 7 and moves with a slope to the holes 8 where it hits changes the direction of the opposite direction. When moving in the annular space
