Abstract

The invention relates to installations for systems for the preparation and filling of cryogenic liquids. The aim of the invention is to improve the economy. The installation includes a turbine 5 with a pump 7 mounted on its shaft 6, an input connected to the receiving diffuser 3. A vapor-liquid heat exchanger 9 is located in the steam extraction pipe 4, the inlet of which is connected to the output of the pump 7, and the output to the input of the turbine 5. The pump 7 increases the pressure due to dissipative losses in it and compressibility of cryogenic liquids, its temperature also increases. In the turbine 5, the flow is expanded, followed by a further decrease in temperature. 1 il. € / 7fffl 1Z

The invention relates to inkjet technology, mainly to jet installations for systems for the preparation and filling of cryogenic liquids.

The purpose of the invention is to increase the eco-identity.

The drawing shows a schematic representation of the described jet device for cooling a cryogenic liquid.

The jet plant for cooling cryogenic contains a booster confusing-diffuser nozzle 1, a curvilinear separating surface 2 located at its outlet, a receiving diffuser 3 and a vapor discharge branch pipe 4. The installation further comprises a turbine 5, a pump 7 mounted on its shaft 6, a connecting inlet 8 to the diffuser 3, and a vapor-liquid heat exchanger 9 located in the inlet 4, an inlet 10 and an outlet 11 of which are connected to the outlet 12 of the pump 7 and the inlet 13 of the turbine 5 respectively At the outlet 14 of the turbine 5, a capacity 15 of collecting cryogenic liquid is installed.

The cryogenic fluid, which is superheated relative to the exhaust pressure, is fed under pressure into the confused-diffuser nozzle 1. In its tapering part, the liquid is accelerated to boiling and in the expansion part, the subsequent flow of the vapor-liquid stream occurs. The temperature of the fluid decreases with this, and its total pressure increases due to the work done on the unaffected fluid by the expanding vapor. Next on the curved separating surface 2 is the separation of the flow. The vapor phase enters the pipe 4 exhaust vapor, and the cooled liquid, with

holding steam inclusions enters the receiving diffuser 3. The pressure recovery in the diffuser 3 is accompanied by vapor condensation and, consequently, an increase in the temperature of the liquid.

A pump 7 driven by a turbine 5 increases the pressure of the cooled liquid. Due to the dissipative losses in the pump and the compressibility of cryogenic liquids, its temperature also increases.

Further, in the turbine 5, the flow of the cooled liquid is expanded to the pressure in the tank 15, also accompanied by a further decrease in temperature.

Thus, the implementation of a jet installation for cooling a cryogenic liquid with a pump, a heat exchanger and a turbine makes it possible to increase the cooling of the cryogenic liquid without energy expenditure and, consequently, increase the efficiency of the jet installation.
