Small household intelligent natural gas filling station

Abstract

The invention discloses a small household intelligent natural gas filling station, comprising a control unit, a compressor unit and a filling unit, wherein, the control unit is communicated with the compressor unit through signal lines, the compressor unit is connected with the filling unit through high pressure flexible pipes, the control unit consists of a PLC (programmable module), a frequencyconverter, a switch power supply, a contactor, a touch screen and a safety management module, and the PLC (programmable module), the frequency converter, the switch power supply, the contactor, touchscreen and the safety management module are electrically connected with each other. Compared with the present natural gas filling station, the small household intelligent natural gas filling station disclosed in the invention has the advantages of small power consumption, low cost, lower filling cost than large-scale filling station, user-friendly operation and high safety. All products are provided with self-developed intelligent management software, so that the filling station disclosed in the invention is a full automation filling station.

Description

technical field [0001] The invention relates to a natural gas filling station, in particular to a small household intelligent natural gas filling station. Background technique [0002] Natural gas is a new type of clean energy. Compared with traditional gasoline and diesel, the main component of natural gas is methane, which produces less carbon dioxide and hydrogen sulfide emissions after combustion, and has a higher combustion value. In order to use natural gas as vehicle fuel, now Some technologies will use natural gas for vehicles after pressurization, desulfurization, dehydration, compression, and storage according to the quality of the existing natural gas. In order to meet the increasing energy demand, traditional gas filling stations adopt high-power compressors, water cooling systems, gas filling machine systems, large pressure storage equipment and transport vehicles used in large gas filling stations for operation and transshipment. One of the reasons restricting...

Problems solved by technology

[0005] The fourth reason that restricts the development of large-scale natural gas filling stations is that imported equipment is required for the construction of the compressor compared to piston rings, safety management software, gas machine flowmeters, high-pressure hoses and joints, resulting in high prices for the complete machine. Insufficient localization further restricts the development of large-scale gas filling stations. Large-scale gas filling stations in my country all use 205BAR as the working pressure. The use of materials and management software design are lower than those in the United States and European countries, and the degree of automation is insufficient.

Therefore, the gas filling stations currently used in my country can only be used in county-level cities and places with soft and high natural gas pipeline network pressure, and cannot be implemented in rural areas.

At the same time, due to the high cost, the current number and scale of gas filling stations cannot support the development needs of existing natural gas vehicles
