DEVICE OF THE DAY

The proposed device for chemical water treatment can be used in the chemical, fuel, metallurgical industry, i.e. where chemical purification of water is carried out and its softening is required.

A known method of magnetic processing of liquids (patent 2010009, MF 5S02G 1/48, BI No. 6, 1994), for example water for heat exchangers, including passing 20 ... 30 of the required amount of water through a magnetotron and mixing this volume with the rest of the volume of water immediately before it enters the heat exchanger.

Also known is a simplified scheme of single-stage Wa cation with wet storage of the reagent, selected as a prototype (D. Borshchov, Cast-iron and steel heating boilers, M ,, Energoizdat, 1992, pp. 232-234). This scheme contains a salt solvent connected in series with the pipeline along the water to be processed, raw crude water supply pipe: a baaonite filter having a drainage and chemically purified water outlet pipe and connected through a loosening washing water tank and water valves.

But this scheme does not provide the safety level required by the modern level.

The aim of the proposed technical solution is to increase the efficiency of water treatment plants by 1 a-cationization by increasing the ion-deceptive ability of cation exchanger in a K / a-cation exchanger, which reduces the consumption of reducing reagent and reduces the amount of wastewater.

IPC С02Р 1/42, С02Р 1/48

The essence of the claimed utility model lies in the fact that a device for chemical water purification, comprising a salt solvent sequentially connected by a pipeline along the treated water, a crude untreated water supply pipeline, a cation filter, having drainage and chemically cleaned pipelines, 1 water and connected through a looser to a water tank washing, water valves, contains two magnetic processing apparatus, one of which is installed directly in front of the cation exchange filter, and the other is pos le him.

The placement of magnetic treatment apparatus directly in front of the cation exchange filter and after loading provides a more complete cleaning of suspended particles of untreated water, deeper water softening, which can significantly reduce the load on the cation filter, prevent clogging of its carbonate and increase its performance. In this magnetic treatment, all water passing through the filter, including brine, is increased, increasing its activity. The effect of magnetic treatment on flushing water from loosening accelerates the coagulation of suspended particles and salts, thereby reducing environmental damage.

The drawing shows a diagram of the inventive utility model.

A device for chemical water purification contains a salt-solvent 2 connected in series with the pipeline I in series along the treated water, a raw water supply pipe 3, magnetic treatment apparatuses 4 and 5, one of which is installed in front of the cation exchange filter 6, and the other after it. The cation exchange filter 6 has a drainage outlet pipe 7 and chemically purified water pipe 8 and a pipe I is connected through a ripper 9 to a washing water tank 10. During the operation of the device, the water backdoors 11,12,13,14,15 and 16 are in the open and closed position.

y - The device operates as follows.

Water after purification from mechanical impurities enters through the water valve II, the magnetic processing apparatus 4 into the upper funnel of the cation exchange filter 6 and is distributed evenly over the entire cross-sectional area of the filter, passing through sulfonated coal

from top to bottom, in this case sodium cations exchange during filtration with cations of calcium and magnesium and form sodium salts in softened water with high solubility, unable to form scale on the walls of boilers and pipelines.

Softened filtered water through a magnetic treatment apparatus 5, a water valve 12, a chemically purified water pipe is removed from the filter 6. As soon as the hardness of the softened water begins to increase, the cation exchange filter 6 is stopped for regeneration.

To do this, first carry out the operation of loosening cation exchange resin. The water valve 13 is open, include pumps Hj and Hg opener

9and periodically open the valve 15 to drain the water into the drain. The clarification of the drainage water determines the duration of loosening. Then open the valves 14 and 15, the remaining valves close. Salt solution through the pipeline I through the apparatus 4 of the magnetic processing enters the cation exchange filter 6, is passed from top to bottom through the cation exchange resin, while restoring its ion exchange capacity. After charging the cation exchanger with new exchangeable sodium cations, the cation exchanger again gains the ability to soften hard water. Then, the cation exchanger is washed to remove regeneration products and residual sodium chloride. To do this, open the water valves 11,15 (the valves 12,13,14 and 16 are closed), wash water is drained into the drainage pipe I, and then sent to the water tank

-1

The washout is stopped when the year becomes prosraldo, it is necessary:.: 1.estcost11. Close the EDI PROJECT 1, go to the process of softening the original hard iodine.

The use of the inventive device for chemical water treatment by 20-30 / increases the efficiency of the treatment plants, reduces the consumption of Bosstavlenny reagent, reduces the amount of waste BOD,
