Abstract

The application relates to the technical field of natural gas pressure regulation, and in particular to a combined power generation and ice-making system utilizing the residual pressure of natural gas. This application provides a combined system for power generation and ice making using natural gas residual pressure. The system includes: a first pressure regulating device and a natural gas regulating ice making device; the first pressure regulating device includes a first pressure stabilizing valve, a first Pre-cooler, heater, second pressure stabilizing valve, first expander, first generator and first heat exchanger; natural gas regulating ice making device includes first water storage tank, first compressor and second compressor , condenser, cooling tower, first throttle valve, second throttle valve, evaporator and ice machine. Through the specific connection relationship, this application can utilize the residual pressure and cold energy generated by the upstream high-pressure natural gas during the pressure regulation process, so that the residual pressure can generate electricity and the cold energy can make ice, which improves the energy utilization efficiency and improves The economy of natural gas operation.

Description

technical field [0001] The application relates to the technical field of natural gas pressure regulation, and in particular to a combined power generation and ice-making system utilizing the residual pressure of natural gas. Background technique [0002] At present, the transmission of natural gas generally adopts the method of high-pressure transmission. With the development of natural gas pipeline technology, the transmission pressure of natural gas worldwide is getting higher and higher. The design pressures of gas pipelines in various countries are: the pressure of natural gas transported in Germany and Italy is 8MPa, the pressure of natural gas transported in the United States is 12MPa, and so on. As far as the pressure of natural gas transportation in my country is concerned, the gas transmission pressure of the "West-to-East Gas Pipeline" and the "Shaanxi-Beijing Second Line" has reached 10MPa, the pressure of the Shaanxi-Beijing Line is 6.4MPa, the Zhongwu Line is 6...
