Abstract

The invention can be used to utilize the heat of thermal water (TB), or for heat supply. The goal is to increase efficiency by reducing heat loss. Geothermal device contains connected to the well (C) 1 separator ATP 2 of the first stage, equipped with a pipe (PTV) 3 tap TV and pipe (PGZH) 4 tap gas-liquid mixture. The first is connected to the consumer (P) 5 heat, the second is located in the upper part of ATP 2 and is connected to the separator (CBC) 6 of the second stage. The latter is equipped with a gas outlet pipe 7 communicated with C 1 and a branch pipe 8 of the separated water outlet connected to ATP 2 at the level between the PGRH 4 and PTV 3. When the PG is operating, ATP 2 separates the TV according to the gas content. GW almost without gas is supplied to P 5, and the rest of the TV through PAGGS 4 - to CBC 6, from where gas is fed back to C 1, and TV - to SPS 2. HEAT LOSSES REDUCED BY CURRENT RETURN TV from CBC 6 to P 5 along the way Tv 1 il.

Description

The invention relates to heat supply And can be used in geothermal devices with the extraction and use of geothermal water.

The purpose of the invention is to increase efficiency by reducing heat loss.

The drawing shows a diagram of a geothermal device.

The geothermal device contains a separator 2 connected to the well 1 of the first separation stage, equipped with nozzles 3 and 4 of the outlet of thermal water and gas-liquid mixture, respectively, the first of which, nozzle 3, is connected to the heat consumer 5, and the second is located in the upper part of the separator 2 and is connected to the separator 6 of the second stage of separation. The separator 6 is equipped with a pipe 7 of the gas outlet connected with the well 1 and a pipe 8 of the separated water connected to the separator 2 of the first stage at a level between the pipes 4 and 3 of the outlet of the gas-liquid mixture and thermal water.

Well 1 is equipped with a gas pipe 9 connected through a valve 10, a pump 11, a shut-off valve 12 and a flow meter 13 to the gas outlet pipe 7. Well 1 is connected to the separator 2 of the first stage through valve 14 and the flow meter 15. Pat felling 4 of the outlet of the gas-liquid mixture of turnkeys to the separator 6 of the second stage through • the control valve 16 and the flow meter 17. The separator 6 is equipped with a regulator 18 of the water level, and its branch pipe 8, the discharge of separated water is connected to the separator 2 through a shut-off valve 19 and a pump 20. The device is equipped with a control valve 21, a shut-off valve 22, pumps 23 and 24, pressure gauges 25 and 26. The separator 2 of the first stage has a drainage device 27. The consumer 5, the heat pipe 28 is connected to the injection well 29. The top of the separator 6, the second stage separation gas outlet valve 30 is mounted.

Geothermal device operates as follows.

Thermal water with gas contained in it from a lifting well 1 is fed through a shutoff valve 14 to a first stage separator, where, under the influence of gravity, thermal water is stratified by gas concentration. The gas-liquid mixture with increased gas content is discharged through the pipe 4 to the separator 6 of the second stage, and thermal water through the control valve 21 to the heat consumer 5, where the thermal water transfers heat to the mains water and then is pumped into the injection well 29 by the pump 24. In the separator 6, the second the stage is the final separation of gas and water. The latter through the pipe 8 is fed into the separator 2 of the first stage, and gas through the pipe 7 using the pump 11 is pumped through the gas pipeline 9 into the well 1. The level 18 controller maintains the water level in the separator 6 by turning the pump 20 on and off. The pump 23 is designed to maintain pressure at the outlet of the heat exchanger (heat consumer 5) is higher than the pressure in the separator 2 of the first stage to prevent the release of gas from thermal water, which causes a violation of chemical equilibrium and can lead to precipitation from the thermal th water and sediment in the pipe 28 and the well 29.

The amount of gas in the separator 2 of the first stage is gradually increasing due to the gas coming from the reservoir thermal water. Due to this, the amount of gas injected into the well 1 through the gas pipeline 9 also increases. With a certain amount of gas in the thermal water injected into the well 1, the maximum flow rate is achieved. A further increase in the amount of injected gas leads to a decrease in flow rate. The moment of the beginning of the drop in the flow rate of thermal water is fixed by a flow meter 15 and the further flow rate of the injected gas is kept constant by means of a control valve 30 and a flow meter 13. If the exhaust gases are combustible, they are sent to a burner (not shown) for heating the mains water.

-, 3a by supplying the separated water to the separator 2 before the consumer 5 of heat along the thermal water, heat loss with thermal water is reduced.
