Abstract

The invention relates to a power system and can be used for the degassing of disinfection hours of supply water from a heat network with an open hot water system. The purpose of the invention is to reduce energy consumption and metal consumption. The make-up water is supplied to the water treatment unit 1, and then enters the decarbator 2 and then through the deaerator 4 is introduced into the return network water line 6. In the calciner 2, the water is treated with air enriched with ozone. In order to enrich the ozone, the installation is equipped with a supercharger 11 and a vortex ozone generator 12, the outlet 13 of which is connected to the air inlets of the calciner. At the same time, energy consumption and metal consumption are reduced, since for the disinfection of water does not require energy costs and the use of metal-consuming devices, 2 Il.

Description

The invention relates to a power system and can be used for the degassing and disinfection of subsurface heating water with an open hot water system.

The circuit of the invention is to reduce power consumption and metal consumption.

FIG. 1 is a schematic installation diagram; in fig. 2 - its calciner.

The installation contains a chemical water-supply unit 1, a calciner 2 with a storage tank 3 and a vacuum deaerator 4 installed in series on the make-up water inlet line 5. Line 5 is connected to the pipeline 6 reverse network heating network; c-hrsrzhaschey top 7 and bottom 8 network heaters, network pump 9 and heat consumer 10.

The installation is equipped with a supercharger 11 air and a vortex generator 12 ozone with the outlet 13.

Decarbonizer 2 contains a nozzle apparatus 14 for introducing water, states of confused nozzles 15, and a mixing chamber consisting of consecutive sections 16-18, to which air inlets 19 and ozone inlets 20 are connected. The nozzles 20 are provided with a nozzle 13 of the ozone generator 12.

The installation works as follows.

it softens, then enters calciner 2, where it is treated with air enriched with ozone. In the calciner 2, water is supplied to the nozzle apparatus 14 and accelerated in the nozzles 15.

Then, in the initial section 16 of the mixing chamber of the calciner, water droplets are crushed, causing an active renewal of the gas exchange surface. In the following sections 17 and 18 of the mixing chamber, atmospheric air is sucked into it through nozzles 19 (due to the injection effect of water flow), and an oeo-air mixture of vortex ozone generator 12 is fed through nozzles 20. By varying the number of pipes 20 connected to the generator, it is possible to adjust the concentration of ozone in the stream discharged through the exhaust pipe of the calciner to the tank 3. The water decontamination process is provided by holding the treated water in the tank 3 of the calciner 2. The subsequent ozone decomposition and release of make-up water from it is carried out in a vacuum deaerator 4, after which the make-up water is supplied to the heat network and mixed with the return network water. The generated water flow is heated in the network heaters 8 and 7 and is supplied to the heat consumer 10. The unused portion of the network water is returned to the heating and electric center.

The proposed installation, without sacrificing the efficiency of the turbine units of the combined heat and power plant, provides simultaneously with the degassing of water after a chemical water purification by disinfecting it by ozonation, which makes it possible to use not industrial water, but not industrial water, as raw make-up water.

At the same time, the plant is more economical and less metal consuming than the known technical solutions, since water disinfection is achieved due to its heating, requiring significant additional energy consumption and additional metal consuming devices (steam-water heater, superheated water tank, surface cooler), and because of its ozonation g decarbonizer. For the scope of the invention.

An installation for the preparation of sub-day water of the heating system, containing a chemical water purification unit sequentially installed on the line of its entry into the return network water pipeline, a calciner with air inlets to a vacuum deaerator, characterized in that in order to reduce energy consumption and metal consumption in an open system hot water supply, it is additionally equipped with a supercharger of air and a vortex ozone generator with inlet and outlet nozzles, the first of which is connected to the supercharger, and the second to the Patr Kills air supply decarbonizer.

Formula and treatment unit for the preparation of heating water supply system containing a chemical water purification unit, a decarbonizer with nozzles for supplying air to a vacuum deaerator, sequentially installed on its inlet line to the return network water pipe, the fact that, in order to reduce energy consumption and metal consumption in a heating system with an open hot water supply system, it is additionally equipped with an air blower and a vortex generator of ozone 35 with inlet and outlet pipes, the first of which is connected to oppressor, and the second - to the nozzles for supplying air to the decarbonizer. then comes' where exposed to enriched ozone. In the decarbonizer 2, water is supplied to the nozzle apparatus 14 and chased in the nozzles 15. Further, in the initial section of the dendrobonizer displacement measure, grinding of water droplets takes place, which causes an active renewal of the gas exchange surface. In the following sections 17 and 18 of the chamber, mixing into it through the nozzles 19, atmospheric air is sucked in (due to the injection effect of the water flow), and through the nozzles 20 an oeo-air-borne mixture of the ozone vortex generator 12 is supplied. By changing the number of nozzles 20 connected to the generator, it is possible to control the concentration of ozone in the molasses, which is discharged through the exhaust pipe of the decarbonizer to the accumulator 3. Due to the exposure of the treated water in the storage tank 3 of the decarbonizer 2, the process of water disinfection is ensured. The subsequent decomposition of ozone and the release of make-up water from it is carried out in a vacuum deaerator 4, after which the make-up water is supplied to the heating network and mixed with return network water. The generated water flow is heated in the network heaters 8 and 7 and is supplied to the heat consumer 10. The part of the network water not used by the consumer is returned to the cogeneration plant.
