The pressure regulating valve 30 is provided in the gas supply line 20 to regulate the pressure of the liquefied petroleum gas in the gas state in the gas supply line 20.
Further, as for the ignition gas storage tank 10, it is used to contain liquefied petroleum gas as the ignition gas. The liquefied petroleum gas is a colorless volatile liquid obtained by pressurizing, cooling and liquefying natural gas or petroleum in an oil refinery. The liquefied petroleum gas is extremely easy to self-ignite, so the ignition gas storage tank 10 needs to meet certain safety requirements to ensure the safety of the operation process.

In the present embodiment, the temperature sensor 50 monitors a temperature signal of the liquefied petroleum gas in a gaseous state in the gas supply line 20, and transmits the temperature signal to the controller. The controller receives the temperature signal, performs data analysis on the temperature signal, and controls the heater 13 to heat the liquefied petroleum gas in the tank 11 according to the temperature signal and the flow signal when the temperature signal is smaller than the set temperature minimum value of the ignition gas.
According to the temperature value to be heated, the controller controls the heating switches on the corresponding number of heating elements in the heater 13 to be opened, and the corresponding heating cable circuit is switched on to be electrified, so that the liquefied petroleum gas in the tank body 11 is heated, and the gaseous liquefied petroleum gas meets the temperature requirement of ignition gas.
When the temperature signal received by the controller is greater than the set maximum temperature value of the ignition gas, the controller controls the heater 13 to close the heating switch, and the circuit of the heating cable is cut off, so that the temperature of the liquefied petroleum gas in the tank body 11 is reduced to the temperature range required by the ignition gas.
For the ignition gas system of the liquefied petroleum gas in the embodiment, the tank body of the ignition gas storage tank is provided with the heater, the heater can heat the liquefied petroleum gas in the tank body, so that the liquefied petroleum gas is vaporized and converted into a gaseous state, the temperature of the gaseous liquefied petroleum gas meets the temperature requirement range of the ignition gas, the pressure of the heated and heated liquefied petroleum gas is increased, and the saturated steam pressure of the liquefied petroleum gas in the tank body is increased, so that the arrangement of a vaporizer and a booster pump in the ignition gas system can be omitted based on the action of the heater, and the simplification of the whole system device is realized. Meanwhile, the pressurized gaseous liquefied petroleum gas can enter the gas supply pipeline, the pressure requirement range of the ignition gas is met under the action of the pressure regulating valve, and on the basis that the gaseous liquefied petroleum gas meets the ignition gas temperature requirement range through the heater, the liquefied petroleum gas fully meets the ignition condition of the ignition gas, and effective supply of gas equipment is achieved.
