Description

The invention relates to installations for the reagent purification of liquids, can be used in the technique of water purification in the chemical, engineering and other sectors of the industry and is an improvement of the known installation Compact for water purification, described in ed. se No. 1473302.

The purpose of the invention is to increase the productivity of the installation.

Figure 1 shows the installation Compact, general view; figure 2 - drainage system after washing water after the filters.

The installation consists of inlet pipe 1, inlet tray with weir 2, inlet part 3, semi-submersible switchboard 4, switchgear 5. of cleaning chamber 6, consisting of inclined elements 7, and 8 for collecting sludge, mixer 9 with pipeline 10 for feeding the reagents, a gravel chamber 11 of the chopopre-cell (CWC), a grate 12, for maintaining the load, and / TL of the uniform distribution of the water to be purified, the overflow device 13 from tubular specimens 14 with openings 15 dl in suspension and open ends 16 and 17, respectively, to release clarified aodic and annular space sludge 18. sedimentary part 19 for separating sediment from slurry before it enters the openings 15 of tubular elements 14, sedimentary part .10 for sediment slipping from tubular, 14, devices 21 and 22 for emptying and removing sediment, respectively, from sedimentary parts 19 and 20, chamber 23 of the cleared water of the clarified water supply system, consisting of a collecting chute 24 of pipe 25 with a shut-off device 26 for modifying water into the mixer 27 , before ator 28 for supplying deodorizing agents 29 for supplying chemical additives, filter 30 located under tubular elements 14, cap drainage 31 and outlet pipe 32. A system for flushing water after filter 30 to the canalization and flushing of tubular elements 14, flocculation chambers 11 and mixers 9 consists of receiving hoppers 33, collecting pipe 34 (FIG. 2) with shut-off devices (gate valves) 35 installed on it, pipelines 36 for supplying water for washing tubular elements 14, chambers 11 reformer and mixer 9, shut-off devices 37 and 38, perforated distribution pipelines 39-41, respectively, for washing tubular elements 14, inter-pipe, 0 piootransta 13, flocculation chamber 11 and mixer 9. To empty the inlet part 3, chamber 6, mixer 9 and The chambers 11 are formed by piping 42-44, respectively.

The installation works as follows.

The purified water through the pipeline 1 through the inlet tray with weir 2 enters the inlet part 3. To evenly distribute the water over the cross section of the inclined elements 7 of the chamber 6, a semi-submersible shield 4 and a distributor 5 are installed. In the chamber 6 a non-coagulated suspension falls out, after which the partially clarified water A mixer 9 enters, where a reagent is fed through the perforated conduit 10. From the mixer 9, through the grate 12, the suspension enters the flocculation chamber 11, where the flocculation takes place. then, through the overflow device 13, the suspension intermeaves the intertarget spacestreet 18 and moves with a slope of the holes 15, flowing into them, changes the direction of the opposite. When moving in the intersticele space 18, it slides out of the suspension onto the downstream tubular elements 14 and the sediment slides on the bottom of the sedimentary part 19 followed by drainage of the sediment through the pipe 21. In the tubular elements 14, the smallest suspension precipitates, which slides down the innermost part of the tubular elements into the sedimentary part 20 and removes through the pipeline 22. The clarified water after tubular elements 1-1 is collected and the chamber 23 is poured into the collecting chute 24, where from the pipeline 25 with the open shut-off device 26 enters the mixer 27, where it is mixed with a deodorizing agent coming from the dispenser 28. Chemical additives to obtain the optimum electrokinetic potential of the filter loading of the filter 30, it is fed to the mixer 27 by means of a metering device 29. The final treatment of the water takes place on the filter 30. from where the clarified water is through cap drain 31 and perforated conduit 32 is diverted to a clean water tank. When flushing, the water moves in the opposite direction along the pipeline 32, evenly distributes r slit caliper drainage 31 over the filter 30 area and then through the receiving funnels 33 through the collecting pipeline 34 with the open valve 35 discharged into the sewage channel. To flush the tubular element block 14, the intertubular pipe wander 18 (amsr P

and the mixers 9 with flushing water from any flushing filter 30 is closed completely or partially with a locking device 35, the locking devices 37 and 38 are opened and the washing water is supplied through a pipeline 36, perforated pipelines 39-41, washes the sediment and is drained by devices 21 and 22 and pipelines 44 and 43

The use of an additional system for supplying water to filters and discharging wash water after filters allows separate supply of water to the filter, separate washing of filters, settlers, float chambers and mixers.
