Combined circulation energy supplying system

Abstract

The invention provides a combined circulation energy supplying system, and belongs to the technical fields of heat energy using and heat pumps. A gas compressor, a combustor and a gas turbine form a gas-turbine-device forward circulation system. A compressor, a second compressor, a second condenser, an evaporator, a low-temperature throttle valve, a second low-temperature throttle valve and a low-temperature heat exchanger form a compressed-type backward circulation system. An absorber, a second absorber, a generator, a second generator, a condenser, the evaporator, a throttle valve, a solution pump, a second solution pump, a solution heat exchanger and a second solution heat exchanger form an absorption-type backward circulation system. The gas-turbine-device forward circulation system supplies power to the compressed-type backward circulation system and supplies driving heat loads to the absorption-type backward circulation system. The compressed-type backward circulation system obtains low-temperature heat loads, supplies heat to the outside through the second condenser and supplies heat to the absorption-type backward circulation system through the evaporator. The absorption-type backward circulation system supplies heat to the outside through the absorber, the second absorber and the condenser. The combined circulation energy supplying system is formed.

Description

Technical field: [0001] The invention belongs to the technical field of power, refrigeration and heat pump. Background technique: [0002] In the system where fuel is used for heating by combustion, there is a large temperature difference between the gas formed by combustion and the heated medium; There is also a large temperature difference; in a distributed energy system powered by a gas turbine device, power supply is actually a restrictive additional condition, and there are still situations where the temperature difference cannot be fully utilized in many cases. These situations that cannot realize efficient utilization of thermal energy can be mainly summarized into six aspects: ①Under the condition of no power load, there is a large unusable temperature difference between the gas and the heated medium, which cannot realize efficient utilization of thermal energy; ②Absorption heat pump is equipped , due to the limitation of the working temperature range of the absorpt...

[0002] In the system where fuel is used for heating by combustion, there is a large temperature difference between the gas formed by combustion and the heated medium; There is also a large temperature difference; in a distributed energy system powered by a gas turbine device, power supply is actually a restrictive additional condition, and there are still situations where the temperature difference cannot be fully utilized in many cases

These situations that cannot realize efficient utilization of thermal energy can be mainly summarized into six aspects: ①Under the condition of no power load, there is a large unusable temperature difference between the gas and the heated medium, which cannot realize efficient utilization of thermal energy; ②Absorption heat pump is equipped , due to the limitation of the working temperature range of the absorption heat pump working medium, there is a large temperature difference between the driving gas and the absorption heat pump working medium, and the use of the temperature difference is unreasonable; There is a large temperature difference; in this way, when the steam-driven absorption heat pump is used, the temperature difference utilization is unreasonable; ④Lack of low-temperature heat resources, it is difficult to use the heat energy in the environment; ⑤When the temperature of low-temperature heat resources is very low, it is difficult to find thermal performance and safety performance are satisfactory and suitable for the working medium of the absorption heat pump device;
