Gas-premixing device and method of natural gas gate station

Abstract

The invention relates to a gas-premixing device and a method of a natural gas gate station. The device comprises a gas phase bottle group system, an air compression system and a control system, wherein the gas phase bottle group system and the air compression system are connected with a static mixer arranged on a natural gas pipeline through a first pipeline and a second pipeline respectively; a total control valve is also arranged on the natural gas pipeline; the control system comprises a controller, pressure transmitters, safety stop valves, mixed gas control valves, a first base type oxygen control meter, a second base type oxygen control meter, a natural gas flowmeter and a pressure transmitter; and the pressure transmitters, the safety stop valves and the mixed gas control valves are connected with the controller and are installed on both the first pipeline and the second pipeline, and the first base type oxygen control meter, the second base type oxygen control meter, the natural gas flowmeter and the pressure transmitter are installed on the natural gas pipeline. Propane is injected into the natural gas pipeline according to the natural gas flow, so that heat value of the natural gas is increased; air is added then, so that the heat value of the mixed gas returns to that of the natural gas; and under the condition that the heat value of the natural gas is not changed, the natural gas consumption is saved, and great contribution can be made for increasing economic and social benefits.

Description

technical field [0001] The invention relates to a device for mixing natural gas synergist and air into natural gas at a natural gas gate station, in particular to an energy-saving device for a natural gas gate station. Background technique [0002] At present, natural gas consumption is large and energy is in short supply, so energy saving is imperative. In order to achieve the purpose of saving energy and reducing costs, the Chinese utility model "a new type of fully automatic premixed burner" with the authorized announcement number "CN202195483U" includes a natural gas intake pipe, an air intake pipe, a mixing pipe, an ignition needle, and an ion probe. , the holding furnace, the crucible and the controller, the natural gas inlet pipe, the air inlet pipe are connected with the mixing pipe, the end of the mixing pipe is located at the gas inlet of the holding furnace, the ignition needle and the ion probe are installed at the end of the mixing pipe, and the crucible is loca...
