CNG decompression stops supply Ningxia city gate high voltage regulator station

CNG regulator station process image and structure Application: With the change and environmental protection efforts continue to increase China's energy structure, so that the development and utilization of natural gas has been rapid development Meng, compressed natural gas pipeline wellhead natural gas or compressed natural gas purification, high-pressure storage and transport, arrived at the place of use, multi-stage heat exchangers, pressure directly into the pipe network serves a variety of users. CNG regulator station to use less than 300 kilometers in the economic sphere, generally no more than 500 kilometers, the size of 2000-4000 households supply. Gas supply 200-5000Nm3 / h is appropriate, too large or too small can cause the unit to increase the cost of gas. The system is a long-distance pipeline of small scale investment, short construction period, faster recovery of funds in the future as a long-distance gas peak shaving and standby source line. Pressure tank car skid preheated high pressure natural gas, step by step down, and security control and metering, plus the olfactory processes the gas pressure to comply with regulatory requirements: CNG compressed natural gas regulator station Process description regulator station works transportation to the pipeline. By regulating mechanism can be divided into two and three surge surge. CNG compressed natural gas regulator station structure Introduction regulator station functions of the device in accordance with the arrangements and equipment inside the station is divided into: unloading system (high-pressure hose, quick connectors, high pressure valve) regulating heat exchange system (high-pressure emergency shut-off valves, heat exchangers , voltage regulators, relief valves) flowmeter system (meter) Control system (center console) heating system (gas boilers, heat pumps, etc.) First pry the car after unloading system into the high pressure natural gas regulator exchanger system, within the regulator after two heat exchanger system, two or three times to enter the regulator flow measurement and processing stinking system and then into the pipe network. Gas heating system provides heat during the required pressure, the control system of the entire system can be monitored. Surge process: A secondary regulator process: First, high-pressure hoses and quick connectors and skid steel tank connections, compressed natural gas shut-off valve through ball into the primary heat exchanger and high-pressure, in the primary heat exchanger gas heating, and then after a pressure regulator to 1.0-4.0MPa, through two heat exchangers heating and secondary regulator regulator to 0.1-0.4MPa, enter the flow meter flow calculation, the last of the gas be odorized, the input pressure pipe network. Switching gas pressure regulator station at all levels, temperature, flow rate, water temperature, critical control valves and two-way linkage between control by the center console. B. Three regulating process: first with high-pressure hose and quick connect fittings skid steel tank, compressed natural gas shut-off valve through ball into the primary heat exchanger and high pressure in the primary heat exchanger for heating the gas, then through a pressure regulator to 3.0-7.5MPa, through two heat exchangers heating and secondary regulator regulator to 1.6-2.5MPa, and then by three after entering the meter regulator to 0.1-0.4MPa traffic measurement, the last of the fuel gas odorization, input pressure pipe network. Switching gas pressure regulator station at all levels, temperature, flow rate, water temperature, critical control valves and two-way linkage between control by the center console.
