With the change and environmental protection efforts continue to increase China's energy structure, so that the development and use of natural gas has been the rapid development of the compressed natural gas pipeline after the wellhead natural gas or compressed natural gas purification, high-pressure storage and transportation, to reach the point of use, after more than grade heat, pressure directly into the pipe network serves a variety of users. CNG regulator stations to use in the range of less than 300 km to the economy, generally no more than 500 km, serving size 2000-4000 households. Gas supply 200-5000Nm3 / h is appropriate, too large or too small will increase the unit cost of gas. The system is a long-distance pipeline investments are small, short construction period, the recovery of funds quickly, peaking in the future as long-distance pipelines and alternate air source. Pressure will pry preheated high pressure natural gas tank car, 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 transported to the pipeline. By regulating mechanism can be divided into two and three regulator regulator. CNG compressed natural gas regulator station structure Introduction regulator station in accordance with the function of the device inside the station layout and equipment is divided into:?? Unloading system (high-pressure hose, quick connectors, high pressure valve) regulating heat exchange system (high-pressure emergency shut-off valve, for thermal, voltage regulators, relief valves)? flowmeter system (meter)? control system (center console)? heating systems (gas boilers, heat pumps, etc.) first prize after unloading the car's high-pressure natural gas system to enter the regulator heat exchange system, in regulating heat exchanger system twice, twice, or three times to enter the regulator flow measurement and processing stinking system and then into the pipe network. Providing a gas heating system heat required for the process pressure, the control system of the entire system to be monitored. A. secondary regulator regulator ??? craft process: First joint and skid steel tank with a high pressure hose and quick connect installation, compressed natural gas shut-off valve through ball into the primary heat exchanger and pressure in the primary heat exchanger within the gas is heated, and then through a pressure regulator to 1.0-4.0MPa, through two heat exchangers heating and two booster regulator to 0.1-0.4MPa, enter the flowmeter flow calculations, and finally were added to the gas smell, the input pressure pipe network. Switching gas pressure regulator station levels, temperature, flow, water temperature, critical control valves and two-way linkage between control by the center console. B. III regulator process: first with a 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, and then through a pressure regulator to 3.0-7.5MPa, through two heat exchangers heating and two booster 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 gas were added to stink, the input pressure pipe network. Switching gas pressure regulator station levels, temperature, flow, water temperature, critical control valves and two-way linkage between control by the center console.
