Description

(54) REFRIGERATING GAS TRANSFER UNIT

one

The invention relates to refrigeration equipment, namely to refrigeration gas pumping units.

Known refrigeration gas pumping units, containing a compressor, a gas expander, a gas turbine and an air blower, a heat recovery boiler, a combustion chamber and a cooler mounted between the compressor and the gas expander, mounted on the same shaft, the gas turbine outlets and the air blower are connected through a recuperative heat exchanger respectively to the cat y-utilizer and to the combustion chamber, which is also connected to the main gas pipeline by means of autonomous Noah spray machine 1.

However, such units are of low profitability due to the beneficial non-use of carbon dioxide and water distillate, leaving the flue gas recovery boiler, the expansion machine consists only of a pipe expander, which is not efficient enough in terms of cooling capacity.

The purpose of the invention is to increase efficiency.

This del is achieved by the fact that the unit additionally contains a series-connected chlorella 5 growth bath, a fan, a gas-air mixer and a condenser with a distillate collector connected to the outlet of the waste-heat boiler, and the expansion machine is designed as one shaft of the screw expander and compressor, the cooling cavities of the heat exchangers-regenerators are included, respectively, in the communication line of the main gas pipeline with the compressor and between the outputs ohm screw expander

5 and the inlet of the screw compressor, and the heating cavities in the communication line of the cooler with the expander and the gas pipeline with the entrance to the expander screw expander.

The drawing shows a schematic

the proposed unit.

Claims (1)

It contains a compressor 2 installed on one shaft 1, a gas expander 3, a gas turbine 4 and an air blower 5, a boiler-boiler 6, a combustion chamber 7, an air-cooled cooler 8, a main gas pipeline 9, a regenerative heat exchanger 10, a growth bath 11 . Merellas, fan 12, air-gas distributor 13, air-cooled condenser 14 with distillate collector 15, heat registers-heaters 16 and 17, screw expander 18, mixed on one HL): shaft 19 with screw compressor 20. In addition, the drawing shows a steam turbine And, to steam condenser 22, deaerator 23, condensate pump 23, boiler 25, heat consumer 26, cold consumer 27, cooler cooler 28 and electric generator 29. The unit operates as follows. Natural gas is sucked from the gas pipeline 9 through the heat exchanger regenerator 16 by the compressor 2 and is injected through the cooler 8 and the heat exchanger regenerator 16 into the expander 3, in which it expands, ooh / 1 and flows into the gas pipeline 9. On one shaft 1 with the compressor 2 and the gas turbine 4 and the air blower 5 are installed by the expander 3, while the gas turbine drives the rotation shaft 1 and all the equipment installed on it. Fuel gas enters the combustion chamber 7 from the main gas pipeline 9 through a heat exchanger regenerator 17 and an expansion machine consisting of a screw expander 18 and a screw compressor 20 on the same shaft, in which it is burned in the medium of air supplied by the air blower 5 through a recuperative heat exchanger 10. The waste gases from the gas turbine 4 are directed through a recuperative heat exchanger 10 to the waste heat boiler 6, in which high-pressure steam is produced, directed to the steam turbine 21 to rotate the electric rotor generator 29, and low pressure steam to produce hot water in boiler 25. The flue gases cooled in the recovery boiler 6 are fed to condenser 14, in which they are further cooled and freed from water vapor accumulating as a distillate in collection 15 Next, the dried gases are mixed in the mixer 13 with air and the fan 12 is directed to the bath 11 for growing chlorella. The exhaust steam from the steam turbine 21 is liquefied in the condenser 22, and the condensate generated enters the deaerator 23, which is also fed with distillate from collector 15. Condensate and distillate after the deaerator are fed by pump 24 to the recovery boiler 6. The cooling effect resulting from expansion The fuel gas contained in the screw expander 18 is used to reduce the chl a temperature to the carrier circulating between the coolant 28 and the cold consumer 27. Hot water from boiler 25 is supplied to heat consumer 26. The use of the present invention allows for more complete utilization of secondary energy resources. Claims: Refrigerating gas pumping unit comprising a compressor, an expander, a pelvic turbine and an air blower, a waste heat boiler, a combustion chamber and a cooler located between the compressor and the expander mounted on the same shaft, the latter connected to the gas pipeline, the outlets from the gas turbine and the air blower are connected through a recuperative heat exchanger, respectively, to the recovery boiler and to the combustion chamber, which is also connected to the main gas pipeline by means of An onom expansion machine, characterized in that, in order to increase efficiency, the unit further comprises a chlorella growing bath, a fan, a gas / air mixer and a condenser with a distillate collector connected to the outlet of the waste heat boiler, and two heat exchangers of the generator; made in the form of a screw expander and compressor placed on the same shaft, the cooling cavities of the heat exchangers-regenerators are included in the communication line respectively a gas pipeline with a compressor and between the outlet of the screw expander and the inlet of the screw compressor, and the heating cavities in the communication line of the cooler with the expander and the gas pipeline with the entrance to the screw expander of the expansion tank.
