Embodiment

[0022] Using CF 4 and C 3 h 8 The binary mixture composed of CF 4 The molar concentration is 0.771, C 3 h 8 The molarity is 0.229. Seawater is used as the ambient heat source at room temperature, and the inlet and outlet temperatures of seawater are 20°C and 15°C, respectively. The cold source of limited cryogenic fluid is liquefied natural gas (LNG), the pressure and temperature are 30bar and -162℃ respectively.

[0023] The low temperature power cycle mode of the present invention:

[0024] Refer to attached figure 1 description, the pressure is 48.6bar, CF 4The mixed working medium solution with a molar concentration of 0.771 is heated to 10°C by seawater, and is generated in the generator (1) into two parts, gas and liquid, with gas accounting for about 97% and liquid accounting for about 3%. The gas enters the first steam turbine (2) and expands to 2.5bar, then enters the reheater (3), is heated to 10°C by seawater and then enters the second steam turbine (4) to ...

Abstract

The invention discloses a low-temperature power cycle system with an absorber, which comprises a generator, a steam turbine, a reheater, a condenser, an absorber, a low-temperature pump and a solution heat exchanger, wherein the working fluid is a binary or polynary mixed working fluid composed of hydrocarbons (HCs), chlorofluorocarbons (CFCs), hydrogen-containing chlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs) and perfluorocarbons (FCs), and cold and heat sources are respectively a limited low-temperature fluid cold source and a normal-temperature environment heat source. The cycle ratio of the invention is obviously superior to the conventional organic Rankine cycle, and can effectively improve the power cycle and the utilization efficiency of the low-temperature cold source energy (cold energy), thereby reducing the waste of energy.

Description

technical field [0001] The invention relates to the field of power circulation, in particular to a low-temperature power circulation system with an absorber. Background technique [0002] In the existing power generation technology, water is usually used as the circulating working medium. Due to the large latent heat of vaporization of water, the cycle efficiency is low, and a large amount of low-temperature waste heat is directly discharged into the atmosphere, wasting a lot of energy. Under the condition of limited cold source of low-temperature fluid and heat source of ambient temperature, it is obviously not feasible to use water as a circulating working medium. [0003] In order to find the working medium suitable for the power cycle of the normal temperature heat source and the finite low temperature fluid cold source, a large number of researches on the organic Rankine cycle (ORC) have been carried out at home and abroad, mainly focusing on the selection of working me...
