Description

air

And: the purchaser relates to refrigeration and engineering, and more specifically to complex energy systems for obtaining heat, cold and carbon dioxide (CO).

The purpose of the invention is to increase profitability.

The drawing shows the scheme of the proposed installation.

The installation contains gas compressor circuit 1, liquefier (one or more) 2 solid CO with heat exchanger 3 and line 4 removing liquid CO with nozzles 5, combustion chamber 6, turbine 7, heat recovery unit 8, water separator 9, regenerator (one or several) 10, desublimator-separator 11 - with a line

The reverse process of sublimation of CO was not performed. Water vapor condenses quite efficiently and with large

speed and then removed in the moisture separator 9. The direct flow is regeneratively cooled in the regenerators 10 to the vapor saturation temperature 00, and it enters the outer contour of the desublimator-separator 11, where on the cold surface the pairs of solid CO are depleted is degraded in the expander 13 with decreasing pressure, temperature and generation

energy. When the temperature in the stream decreases, CO pairs are desublimated, which are separated in the internal circuit of desublimator-separator 11. The reverse flow of gases is heated in

switch, the developed solid C02 is discharged to the consumer, and a part through the control valve 16 is mechanically supplied to the liquefiers 2, the amount of solid CO: that is discharged

and valves 16 and 17,

The installation works as follows. .25

Compressor 1 compresses the atmospheric air, which is then cooled, giving warmth to the solid in the liquefaction agent 2, whereby solid CO goes into liquid state with a pressure increase in closed volume and is supplied to the consumer, and part of liquid CO in the amount of 1-3% through regulating The valve 17 spontaneously, under the pressure gradient, flows through the compressor nozzle 1. Ki 5 into the condensation zone of the water vapor of the flue gas stream leaving the heat exchanger 8. The boilers 2 are alternately switched during operation. The cooled compressed air enters the combustion chamber 6, where fuel is supplied; the fuel / air mixture is combusted. and; flue gases are expanded in turbine 7 with energy production. Further, the flue gases are cooled in the heat exchanger 8 to the dew point temperature, at the same time the generated heat is removed to the consumer. Injection into the gas flow liquid
