摘要
To ensure the non-stop gas supply for users during the maintenance period of a gas pipeline network, a novel mini-scale mobile gas-supply appliance was developed with the LNG steel cylinders as the main supply source for the pipe grid. The major components of this appliance are first introduced, including steel cylinders, carburetor, and odorizing equipment. Optimal design is made on the gas users' consumption, the capacity of a steel cylinder, the installment of heat booster, pressure regulation, and odorization mode, etc. This new appliance is featured by 4 aspects: flexibility and practicability, independent assortment and simple operation, the innovative use of LNG as a gas supply source, good appearance and convenience for mass production. This appliance was tried as temporary gas supply for 236 families in one building, ultimately, it was found that the maximum gas consumption was up to 24.5 m3/h, the lowest temperature of gas was 11 °C. In this case study, this appliance not only completely meets the needs of urgent gas supply but complies with the related national standards. The development and application of this gas-supply appliance fills up the technology blank in the non-stop gas supply under abnormal working conditions in the gas industry; more than that, it also helps the designers get patents for its appearance design and utility model. It will be widely used in gas supply security system.
