Description

The invention relates to heat supply systems of large cities and industrial complexes, mainly from heat sources generated at heat and power plants located at a considerable distance from consumers.

The aim of the invention is to reduce the capital and energy costs of heat supply by eliminating the need to install hot water boilers in the heat of heat 4. After being used as a coolant, the cooled water enters the return line 7, from which it enters the regenerative installation 8. Here, the former air-saturated composition is restored in the cooled water, which is achieved by mixing the sprayed water with an atmospheric-air mass. pools or in bubbling

outlets and waste water discharges in devices. If necessary, the regeneration canalization unit 8 can be adjusted. The drawing schematically shows the siege and the salt composition of the reconstituted

They also include a supply of hot water from the reservoir - battery 11. If there is a shortage of coolant in the pipe 6, hot water is pumped from the network pumping station 12 from the reservoir - battery 11. The latter is filled during periods of minimal heat consumption. Due to the need for large-scale water supply system 1. At the outlet section 25 of the heat supply themes, to have large reserves of one-pipe line 3 before its entry into the hot water (100000 m and more) the distribution network has a mixing tank - the battery 11 has its con10 to control the temperature of the network structural and regime features.

It also regulates the temperature level up to 120 ° C of hot water flowing directly into the pipeline 6 of the distribution two-pipe system.

Thus, the transit single-pipe line 3 performs the functions of feeding both the heating network and the drinking-water pipeline 1, which are, as a rule, at a considerable distance from the sources
