Abstract

The invention relates to an efficient water-saving controllable gas turbine quadruple-cogeneration system. The gas turbine quadruple-cogeneration system is efficient and controllable, saves water and achieves in-plant circulation and zero emission. According to the technical scheme, the efficient water-saving controllable gas turbine quadruple-cogeneration system comprises a gas turbine, an air cooler, a coal gasifier, a cyclone separator, a refrigerating machine, a heat pump, a Rankine cycle system and a low-temperature smoke processing system. The efficient water-saving controllable gas turbine quadruple-cogeneration system fully utilizes available resources, wind energy and solar energy, in a factory, achieves an efficient and controllable gas turbine combustion and acting system and achieves an more economical and adjustable heat-electricity-coldness-hot water quadruple-cogeneration system, a supersonic separation technology is applied to a gas turbine power plant for the first time, the quadruple-cogeneration has the advantages of being high in dewatering efficiency, safe and stable and effectively preventing low-temperature corrosion, low-temperature smoke is efficiently utilized, zero emission is achieved at the same time, waste heat is reasonably utilized, the thermal efficiency reaches 42% or above, and the combined cycle thermal efficiency reaches 63% or above.

Description

technical field [0001] The invention relates to a gas turbine system, in particular to a gas turbine quadruple generation system integrating high efficiency, water saving and controllability. Background technique [0002] The gas turbine has been widely used in the field of power generation. Due to its compactness, high power, and installed advantages, it has become a widely used power machine. At present, the thermal efficiency of the 390MW 9F gas turbine is about 40%, and the combined cycle thermal efficiency Up to about 58%. [0003] However, in the existing combined cycle, there are problems such as waste of heat, large water consumption, uncontrollable and unadjustable triple production of heat, electricity and cooling, low-temperature corrosion, and waste of working fluid. How to solve these problems is a concern of those skilled in the art. Contents of the invention [0004] In view of the above situation, in order to overcome the deficiencies of the prior art, the...
