Flammable and explosive liquid transportation system and method and application thereof

A flammable and explosive liquid transportation system, comprising a gas inlet pipe (1) and a liquid transportation pipeline (10), wherein

• one end of the gas inlet pipe (1) communicates with a raw material barrel (6), the other end of the gas inlet pipe (1) communicates with an inert gas source, a first valve group is disposed on the gas inlet pipe (1), and the first valve group sequentially comprises a first valve (2) and a second valve (4) along a gas flow direction;
• two ends (18) of the liquid transportation pipeline (10) respectively communicate with the raw material barrel (6) and a reaction vessel (15), a second valve group is disposed on the liquid transportation pipeline (10), the second valve group sequentially comprises a third valve (7), a fifth valve (9), and a seventh valve (14), the third valve (7) is disposed near the raw material barrel (6), a one-way valve is disposed on the liquid transportation pipeline (10), the one-way valve is disposed in parallel with the fifth valve (9), and the one-way valve only allows a liquid or a gas to enter the reaction vessel (15) from the raw material barrel (6);
• the gas inlet pipe (1) and the liquid transportation pipeline (10) communicate with each other through a connecting pipe (5), a fourth valve (8) is disposed on the connecting pipe (5), a joint between the connecting pipe (5) and the gas inlet pipe (1) is disposed at a front end of the second valve (4), and a joint between the connecting pipe (5) and the liquid transportation pipeline (10) is disposed at a rear end of the third valve (7) when a liquid is transported from the raw material barrel (6) to the reaction vessel (15);
• and
• a bypass pipe (11) is disposed on the liquid transportation pipeline (10), one end of the bypass pipe (11) communicates with the liquid transportation pipeline (10), the other end of the bypass pipe (11) communicates with a water storage container (13), and a sixth valve (12) is disposed on the bypass pipe (11).
