detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is specifically described:
The utility model relates to a kind of water-steam combination and sprays vacuum refrigerator, as shown in Figure 1, steam distributor 1, flash vessel 2, main steam jet ejector 3, main mixing condenser 4, auxiliary steam jet ejector 5, auxiliary mixing condenser 6, water ejector 7 is mainly comprised, steam distributor 1 connects main steam jet ejector 3 and auxiliary steam jet ejector 5 respectively, flash vessel 2 connects main mixing condenser 4 by main steam jet ejector 3, main mixing condenser 4 connects auxiliary steam jet ejector 5, auxiliary steam jet ejector 5 connects auxiliary mixing condenser 6, auxiliary mixing condenser 6 connects water ejector 7, adopt water ejector to instead of two auxiliary steam injector of similar system and two auxiliary condensers and make that this device is both energy-conservation in turn simplify structure, and lower terminal condensing pressure can be provided, for whole system uses the working steam of power at low pressure to provide the foundation.
The power source of this device is combined by steam and water and provides.
The connected mode of the main steam jet ejector 3 between flash vessel 2 with main mixing condenser 4 is parallel diagonal bridge, main steam jet ejector 3 and the connection inclination angle between flash vessel 2 and main mixing condenser 4 are greater than 15 degree and are less than 90 degree, and the setting water efficiently solved in plant running process in main mixing condenser pours in down a chimney the problem into flash vessel like this.
Main steam jet ejector 3 is equipped with muffler, the noise produced can be reduced during equipment runs greatly.
Flash vessel 2 can adopt the flash vessel of quadruple effect.Main mixing condenser 4 can adopt the main mixing condenser of quadruple effect.Namely this device is made up of the flash vessel of quadruple effect and the main mixing condenser of quadruple effect.In real work, in order to manufacture the needs of large-scale refrigerating plant, the utility model can also install greater number main injection steam compressor.
Operation principle of the present utility model and process as follows:
