Problems solved by technology

[0002] Most of the existing thermal systems use high-pressure superheated steam as the working steam, and steam turbines as the prime movers. Since the working steam needs to be condensed into water through the condenser after being discharged through the steam turbine, a large amount of heat energy is discharged to the outside of the system, so the thermal efficiency of the system is relatively low. low, resulting in energy waste and environmental pollution

Embodiment 1

[0013] Embodiment 1: When fresh water is used as the working fluid, the valves 5-2, 5-4, and 5-5 are closed, and the valves 5-1, 5-3 are opened. At this time, the system is a closed thermal system. Before the system is used, the vacuum pump in the condenser 4 is used to discharge the air in the system, so that the inside of the system is in a vacuum state. One part of high-pressure steam generated by steam generator 1 (the steam generator can be a low-pressure boiler) enters the inlet of ejector 2 to form a high-speed jet, and the low pressure formed by the high-speed jet makes the water at the upper end of evaporator 3 quickly evaporate into n parts of low-pressure saturated steam and Injected into the ejector, the high-pressure steam and the injected n parts of low-pressure saturated steam form 1+n parts of mixed low-pressure saturated steam in the ejector 2 and enter the condenser 4 as the working steam of the system, and the working steam enters the condenser 4 The generat...

Embodiment 2

[0014] Embodiment 2: When seawater is used as the working medium, the valves 5-1 and 5-3 are closed, and the valves 5-2, 5-4 and 5-5 are opened. At this time, the system is an open thermal system. The working process of the open thermal system is basically the same as that of the closed thermal system in Embodiment 1, except for the following differences: one is that the cold water in the cold water zone 3-2 in the evaporator becomes cold concentrated seawater, which is transported to the condensate by the water pump 6-1. After the steam turbine 4 absorbs heat, it will not return to the evaporator 3, but will be output to the outside of the system through the valve 5-2 through the drainage pipeline E to be used as chemical raw materials; the second is to introduce seawater outside the system through the valve 5-4 through the water supply pipeline G The evaporator 3 is used to supplement the consumption of seawater in the system; the third is that fresh water steam is still inje...

Abstract

The present invention relates to a new thermodynamic system which is composed of steam generator, ejector, evaporator, steam condenser. The said system uses mixed low pressure saturated steam produced by the steam generator and steam jet refrigeration system as working steam, reduces the ratio of high-pressure steam in the working steam; it uses the cold water in steam jet refrigeration system ascirculating cooling water for the steam condenser, it adsorbs a large part of gasifying latent heat released during condensing of working steam and carries back to the evaporator for reuse, thereby achieves the aim of increasing system heat efficiency, energy saving and environmental protection. The invented system also possesses the function of desalination of sea water.

Description

(1) Technical field: [0001] The invention relates to a thermodynamic system, in particular to a new thermodynamic system using low-pressure saturated steam produced by a steam injection refrigeration system as working steam. (two) background technology: [0002] Most of the existing thermal systems use high-pressure superheated steam as the working steam, and steam turbines as the prime movers. Since the working steam needs to be condensed into water through the condenser after being discharged through the steam turbine, a large amount of heat energy is discharged to the outside of the system, so the thermal efficiency of the system is relatively low. low, resulting in energy waste and environmental pollution. [0003] On April 14, 2000, the China Intellectual Property Office authorized a utility model patent named "condensing steam power device", patent number: 99221682.6; on July 4, 2001, another patent named "condensing steam power method and device" patent application. ...
