Example Embodiment
[0067] Example 1
[0068] In this embodiment, the gas supply device uses a gas cylinder, such as figure 2 As shown, a digital pressure gauge 4 is also installed on the pipe E at the outlet of the gas cylinder, which is used to monitor the pressure in the gas cylinder in real time.
[0069] When this embodiment is used as a gas supply system for a shoe machine, anhydrous monomethylamine gas is stored in the gas cylinder, and the pressure control valve 3 is opened. After the gas in the gas cylinder enters the buffer tank 2, when the pressure in the buffer tank 2 reaches After a certain value (this value is much smaller than the pressure in the cylinder), the buffer tank 2 is completed and the pressure control valve 3 is closed; when the shoe machine runs to the need to enter methylamine, the buffer outlet valve 5 opens, and the gas enters the pipeline F and passes through The gas filter 6, the gas mass flow controller 7, and the flow outlet valve 1-1 enter the shoe machine cavity 8 ...

[0071] Example 2
[0072] In this embodiment, the gas supply device adopts a solution heating device, such as image 3 As shown, the gas supply device 1 includes a raw material tank A11, a raw material tank B12, a heating device I12, and a condenser I14. The bottoms of both the raw material tank A and the raw material tank B are equipped with a heating device I. The heating device I is preferably a heat transfer oil heating device ( It can be heated to 60-200℃) or a water bath heating device (can be heated to 60-100℃). The use of heat-conducting oil or water bath heating can effectively control the heating temperature and always stay within a safe range; Condenser I passes through pipe A1-5 and pipe B1 -6 is connected to raw material tank A and raw material tank B, and communicates with the inlet of buffer tank 2 through pipeline E. Pipes A1-5 and B1-6 are respectively equipped with outlet valve A15 and outlet valve B16, raw material tank A and raw materials The top of the tank B...
