Water treatment plant VPU-12.0 is designed to soften feed water, used for boiler units and other facilities where softened water is required. The main elements of the VPU-12.0 unit are: a counterflow ion exchange filter, a salt solution preparation tank, an electric pump unit, pipelines and fittings. The equipment of the unit is mounted on a frame. The operation of the VPU-12.0 installation includes the following operations: softening of water; loosening of the cation exchanger; regeneration of the cation exchanger; washing of the cation exchanger from the regeneration products. During softening, the source water is pumped into an ion exchange counterflow filter and, passing from top to bottom, enters the feed water tank. To loosen the blocking layer of the cation exchanger, the source water enters the middle distributor of the ion exchanger and is discharged through the upper distributor into the gravity drainage. The loosening process is carried out until the discharge water is completely clarified. Periodically (after 10-20 filter cycles), the entire layer of the cation exchanger is loosened. Regeneration of the cation exchanger is carried out with a 5-8% solution of sodium chloride. To prepare this solution, the initial water is supplied to the ejector, where a 20-25% salt solution is simultaneously supplied from the tank. Regeneration of the cation exchanger is carried out in two streams. The main part of the 5-8% regeneration solution (~ 76%) is fed into the lower distributor of the filter and passes through the auxiliary and main layers from the bottom up. The rest of the flow (~ 24%) is fed into the upper distributor and passes from top to bottom through the blocking layer. The spent regeneration solution is discharged through the middle distributor. The cation exchanger is washed with feed water, which is also supplied in two streams, the main stream (~ 76%) enters through the lower distributor. A smaller part of the flow (~ 24%) is supplied through the upper distributor. The wash water is discharged through the middle distribution device into the gravity drain. The end of cleaning is controlled by the hardness of the water after the middle distributor. After the end of washing, the VPU-12.0 unit is transferred to the source water softening mode.

The VPU-2.5 unit operation includes the following operations: softening of water; loosening of the cation exchanger in the ion exchanger; regeneration of the cation exchanger; washing the cation exchanger from the regeneration products; loosening of the clarifying filter cation exchanger; washing of the clarifying filter cation exchanger. During softening, the source water is pumped into the clarification filter, then it enters the ion exchange counterflow filter and, passing from top to bottom, enters the feed water tank. To loosen the cation exchanger layer, the source water, after passing through the clarifying filter, enters the lower distributor of the ion exchanger and is discharged into the gravity drainage system. When clear water appears, loosening is stopped. To restore the ion-exchange capacity of the cation exchanger, the cation exchanger is regenerated with a solution of sodium chloride. Washing of the cation exchanger is carried out with source water, which is supplied from the clarification filter. Loosening and washing of the clarifying filter cation exchanger is carried out when the pressure loss in the filter increases to 0.1 MPa and the quality of the clarified water deteriorates. Loosening of the entire layer of the filter bed is carried out in an upward flow. Loosening of the filter bed is carried out until a sharp clarification of the wash water. After loosening the filter bed of the clarifying filter, it is washed until the wash water is sharply clarified.

The equipment of the unit is mounted on a frame. The production process at the water treatment plant consists in softening the treated water, stopping the filter for regeneration, loosening the cation exchanger by the reverse flow of water. The VPU-1.0 unit operates according to the parallel-precision Na-cationization scheme. Initial water is supplied to the upper part of the filter in the upper distribution device. Having passed through the cationite loading of the filter in the direction from top to bottom, the water softens, exits from the bottom of the filter and is discharged into the feed tank, from where it is disassembled for consumption. As the cation exchange filter depletes, the residual hardness of the softened water increases and, when the maximum permissible value of this value is reached, the unit is turned off for regeneration. Regeneration of the cation exchange filter is carried out with a 6-8% sodium chloride solution prepared in the tank. At the end of the regeneration, the filter is turned on. All equipment of a block water treatment plant - a cation exchange filter, its upper distribution device, a salt solution preparation tank and pipelines are made of carbon steel. The lower distributor of the filter is made of polymeric material.

The cast iron block economizer EB1-808 is a tubular heat exchanger, in which the feed water is heated before entering the boiler to a temperature of 30 - 40 ° C below the boiling point in order to prevent vaporization and water hammer inside it. Heating occurs due to the heat of the exhaust gases, thereby increasing the efficiency of the boiler unit. Economizers consist of bundles of finned pipes, interconnected and enclosed in a frame with a heat-insulating sheathing. Completed (at the request of the customer) with a box for gas supply. The movement of feed water in pipes that make up a common heating surface is towards the flow of flue gases. The use of cast iron in heating surfaces and fittings significantly increases the service life compared to steel economizers. The use of steam (P) or gas-impulse (I) cleaning will allow you to constantly have clean heating surfaces, which means that you save fuel with minimal maintenance and the complete elimination of manual labor. By agreement with the Customer, the economizer can be equipped with a device for cleaning heating surfaces GUV (shock wave generator). Supplied assembled, one transportable unit. The installation of the economizer is reduced to its installation on the foundation, the manufacture and installation of a supply gas duct with explosive safety valves, and its connection to the boiler feed pipelines.
