Cold, heat, water and electricity four-coproduction system combined with freezing method

Abstract

The invention discloses a cold, heat, water and electricity four-coproduction system combined with a freezing method. The system comprises a gas-turbine generator set, a combined heat and power generation system, a seawater ice-making system and a cold and water coproduction system, wherein an exhaust outlet of the gas-turbine generator set is connected with a flue gas inlet of a waste heat boiler of the combined heat and power generation system; a small backpressure machine of the combined heat and power generation system is coaxially connected with a compressor of the seawater ice-making system; an outlet of the compressor of the seawater ice-making system is connected with an inlet of a heater of the combined heat and power generation system; a washing chamber of the seawater ice-making system is communicated with a thawing chamber of the cold and water coproduction system; a circulating water loop is formed among the thawing chamber of the cold and water coproduction system, a plate heat exchanger and a water storage tank; an air conditioning chilled water loop is connected with the other side of the plate heat exchanger; and the water storage tank is provided with a fresh water overflow pipe. The cold, hot, water and electricity four-coproduction system is capable of producing three energy including cold, heat and electricity and outputting fresh water, is very high in energy utilization efficiency, is beneficial to reducing the cost of seawater desalination, and can realize comprehensive utilization of energy and resources.

Description

technical field [0001] The invention belongs to the scope of seawater desalination technology and distributed energy technology, and in particular relates to a quadruple generation system of cold, hot water and electricity combined with a freezing method. Background technique [0002] The rational use of energy and the improvement of its utilization efficiency are not only related to resource conservation and economic development, but also affect the ecological environment and the future of mankind. Therefore, all countries in the world regard the establishment of a reliable, safe, stable and efficient energy supply guarantee system as a sustainable national economy. development strategy. Based on the existing energy-resource allocation conditions and mature technology combination, the distributed energy system pursues the maximization and optimization of resource utilization efficiency to reduce the loss of intermediate links and reduce the pollution and damage to the envir...

Problems solved by technology

However, in the butane freezing method, the low-pressure butane vapor is pressurized by an electric compressor and then the ice crystals are melted, which not only causes the resulting fresh water to be polluted due to a small amount of butane, but also the heat of the butane vapor and the storage capacity of the ice crystals A large amount of cold energy directly offsets each other, and neither of them has been used in the most reasonable way, resulting in a lot of energy waste
