Description

The invention relates to the industrial heat and power industry and is intended for an easy-to-use water softening. The purpose of the invention is to increase the efficiency of operation by preventing heat losses from the evaporation and removal of fine sludge.

The drawing shows the installation water.

The installation comprises a housing 1 with distributor 2 of source water placed in it, connected by an inlet to ejector 3, distributors 4, 5 and 6 of heat carrier, a fine slurry slurry and additional heat carrier with perforation 7 directed upwards, slatted nozzle 8 with fastening 9 ends of rails, as well as a deaerating device with suction gases by a nozzle 10 and a bell 11. The installation contains overflow pipes 12 and 13 with sludge catching pockets 14, one of which is connected by a thermosyphon 15 to a sludge distributor 5. The coolant is supplied to the thermosyphon through fitting 16. Overflow pipes 12 and 13 are connected by siphon 7, the inlet end 18 of which is made in the form of an oblique cut.

The installation works as follows.

The initial water is supplied by the ejector 3 to the casing 1 through the distributor 2. Cold water above the distributor 4 of the heat transfer medium creates a hydraulic thermal shutter, eliminating heat loss with evaporation. Water is heated by a jet distributor 4 heat transfer media, intensive mixing of the source water, heat carrier and entering the mixing zone through the distributor 5 fine sludge seed (crystallization centers) for intensive formation of a solid phase is provided. Efficient heat and mass transfer in the deaeration zone of the water heater is provided with a nozzle 8, made in the form of a lattice. Additional heating of water to equilibrium temperature with vigorous stirring and. the release of equilibrium carbon dioxide at the final stage of the formation of a solid phase. is produced by an additional distributor 4 of the coolant installed in the deaeration zone, and ensures the enlargement of the sludge. Necessary for his

effective withdrawal of water from the mind. To remove aggressive gases, oxygen and carbon dioxide from water, water at the maximum temperature enters the deaerating device; gases are sucked through the suction port 10 by means of a water jet ejector 3. Bell 11 serves for

the collection of gases emitted in the deaeration process. From the deaerating device, water flows through the bypass pipes 12 and 13 to the accumulator tanks; The overflow pipe 12 has a pocket 14 for collecting sludge, which is removed by blowing. Fine sludge is fed by thermosyphon 15 into the mixing zone of the source water with the coolant to accelerate the separation of the solid phase. The operation of the thermosyphon is ensured by the supply of heat transfer fluid through the pe: i fitting 16, the overflow pipes 12 and 13 are connected by a siphon 17, the inlet end 18 of which is made in

the form of an oblique cut to reduce the rate of siphon entry into the softened water, and g: subsequently, and reduce the removal of fine sludge.
