御装置が使用される。The device according to the invention, unlike the devices according to the prior art, works by using direct heat exchange between the gaseous and liquid components. A difficulty to be overcome in the prior art was, above all, the long residence time required for the complete evaporation of the droplets in the gaseous component. For extremely frequent use cases,
Thus, when forming a cooling gas stream from gaseous and liquid nitrogen, the droplets require a mixing section of at least 4 m length for complete evaporation. This section can be shortened, if necessary, by using auxiliary spraying devices, but such a device makes the desired device expensive and slows down depending on the operating conditions. By arranging the mixing section in the pressure vessel according to the present invention, the cooling gas flow manufacturing apparatus can be designed compactly. The pressure vessel simultaneously acts as a pressure pulsation damping device. Furthermore, it is advantageous to provide the pressure-resistant container with a filling consisting of VA-Raschig rings, for example. This filling allows a very precise temperature control, for example in the case of discontinuous operation, i.e. impact operation at constant temperature. In order to achieve fast and precise temperature control, especially in the case of discontinuous operation, control devices are used for pressure and temperature controlled introduction of the liquid components.

Further, the liquid component may contain a solid component, for example, liquid nitrogen containing frozen carbon dioxide particles or a hydrogen slush composed of liquid hydrogen and frozen hydrogen.

According to the invention, a long tubular mixing section 3 is arranged in the pressure vessel 1 and opens inside the pressure vessel 1. The other end of the mixing section 3 communicates with the connecting portion 5 through the lid 4 of the pressure resistant container 1. There are two other connections on the lid 4, a connection 6 for introducing the liquid component, i.e. a connection 7 for discharging the cooling gas flow under pressure. The mixing section 3 is
It is surrounded by a packing 8 consisting of VA-rings, which is arranged in a sieve structure 9. At the bottom of the pressure vessel 1 is a valve 10 through which water can be drained. Water can be separated, for example, if air that has not been sufficiently dried is used as the gaseous component. The device is provided with a relief valve 11 which responds when the pressure in the pressure vessel becomes too high. The supply of the liquid component is controlled by the control device 12 which detects the temperature in the mixing section 3 and the pressure in the connection portion 6. The mixing section 3 is long so as to guarantee complete evaporation of the liquid components even during long-term operation and low temperatures. In the device actually designed, the mixing section 3 is 4 m long.

ｂａｒであり、ガス状窒素は８ｂａｒである。In operation, the gaseous component under pressure is introduced into the mixing section by the connection 5 via the valve 13.
At the same time, the liquid component flows in via the connection 6 via the control valve 14. These quantities are controlled by the controller 12. This gives a freely selectable temperature below the temperature of the gaseous component and slightly above the temperature of the liquid component. The liquid component is under higher pressure than the gaseous component.
The liquid components are jetted into the mixing section 3 where they are evaporated and
It leaves the mixing zone 3 as a cooling gas stream. A cooling gas stream having an arbitrarily selectable pressure can be discharged from the device by means of the connection 7 and the valve 15. This pressure can be arbitrarily selected up to the allowable operating temperature of the pressure resistant container 1. However, it is premised that the pressure of the liquid component is higher than the pressure of the gaseous component. In the case of discontinuous operation, the pressure of the liquid component is 0.1
Higher by ~ 1.5 bar is sufficient. For example, gaseous nitrogen is operated at 8 bar, liquid nitrogen is 8.1-9.5.
It is operated by bar. In the case of continuous operation, the pressure of the liquid components can be significantly higher, for example liquid nitrogen of 15
bar and gaseous nitrogen is 8 bar.
