Problems solved by technology

The utilization efficiency of natural gas is high, which is beneficial to environmental protection. However, the utilization of natural gas is still in its infancy, and there is no unified form for the natural gas pressure regulating station. Rapid response to changes directly affects the safe operation of user equipment, increases maintenance costs, and reduces the service life of gas station equipment, which in turn makes investment and operating costs too high

Embodiment Construction

[0009] The function of the natural gas pressure regulating station is to provide continuous and stable natural gas that meets the requirements of gas users for flow, pressure, and temperature. In the event of a fire, the pressure regulating station can be quickly cut off. The pressure regulating station has sufficient relief and buffer measures to weaken the impact on the pressure regulating station due to the sudden change in the gas flow of gas users. When switching between the pressure regulating branches, large pressure fluctuations should be avoided. The process flow of the present invention is as figure 1 Shown in.

[0010] The inlet insulation and fire alarm cut-off unit 1 is mainly composed of an insulating joint, a fire alarm cut-off valve, a temperature sensor, a pressure sensor and so on. The insulation joint is mainly to avoid the influence of the electrochemical corrosion of the buried gas pipeline on the pressure regulating station; the pressure and temperature o...

Abstract

The invention discloses a natural gas pressure regulator station system. The natural gas pressure regulator station system is characterized by comprising an inlet insulation and fire alarm cut-off unit, a cyclone separation unit, a filter separation unit, a measuring unit, a pressure regulating unit and an outlet unit, which are sequentially connected together. A pressure regulator station is far away from a gas user, a front module of the natural gas pressure regulator station system is arranged in front of the gas user, the front module comprises a front measuring unit, a front fine filter unit and a front insulation and fire alarm cut-off unit. The natural gas pressure regulator station system has advantages that the investment and operation cost can be reduced, and the stability and safety for supplying the natural gas can be improved; a complete auxiliary facility is also provided on the basis of a heating unit and a front unit for the gas consumption characteristics and upstream gas source parameters of the gas user, so that the safety and stability of the pressure regulator station system in operation can be guaranteed, and the requirements of the gas user on high natural gas parameter accuracy and high response speed can be met.

Description

Technical field [0001] The invention relates to the technical field of natural gas application, in particular to a natural gas pressure regulating station system for regulating (pressurizing), metering, controlling and transporting natural gas. Background technique [0002] As my country’s reserves of oil and coal continue to decrease, and the proportion of natural gas in primary energy sources is too small (less than 4%), low-carbon development requires China’s natural gas to account for 15% to 20% of primary energy in the next 20 years. The main urban primary energy and industrial fuels. In October 2011, the National Development and Reform Commission, the Ministry of Finance, the Ministry of Housing and Urban-Rural Development, and the National Energy Administration jointly issued the "Guiding Opinions on the Development of Natural Gas Distributed Energy", detailing the important significance and policy measures of the development of distributed energy. [0003] Natural gas is a ...
