Embodiment Construction
[0012] An embodiment of a vacuum system that can prevent liquid chlorine from pouring in backwards, in figure 1 Among them, a gas phase pipe 2 is connected between the two ends of the liquid phase pipe 1, a connecting pipe 3 is connected between the two ends of the gas phase pipe 2, and the other end of the connecting pipe 3 is connected to an exhaust gas buffer tank 4 , the connecting pipe 3 communicates with the exhaust gas buffer tank 4 in the middle of the exhaust gas buffer tank 4, that is to say, the connection point between the connecting pipe 3 and the exhaust gas buffer tank 4 is neither at the upper end of the exhaust gas buffer tank 4 nor at the exhaust gas buffer tank 4, the upper end of the waste gas buffer tank 4 has an air outlet, which is used to be connected with the waste chlorine absorption device, and is connected with an air outlet pipe 5 on the air outlet, and an on-off valve is arranged in series on the air outlet pipe 5. A slag outlet is provided at the...

The invention discloses a vacuumizing system capable of preventing reversed filling of liquid chlorine. According to the vacuumizing system, a gas-phase tube is arranged on a liquid-phase tube in a communication manner; a connection tube is arranged on the gas-phase tube in a communication manner; the other end of the connection tube is connected with a waste gas buffering tank; the connection tube communicates with the waste gas buffering tank at the middle part of the waste gas buffering tank; a gas outlet port connected with a waste chlorine removal and absorption device is arranged in the upper end of the waste gas buffering tank; a residue outlet port is arranged in the lower end of the waste gas buffering tank; switch valves are serially arranged on the liquid-phase tube and at the two sides of the gas-phase tube respectively; an electromagnetic switch valve is serially arranged on the liquid-phase tube and between one switch valve and the gas-phase tube; switch valves are serially arranged on the gas-phase tube and at the two sides of the connection tube respectively; a switch valve is serially arranged on the connection tube; a temperature control device is arranged at one side of the waste gas buffering tank; a temperature sensor of the temperature control device is arranged in the waste gas buffering tank; and a circuit is controlled to start and the electromagnetic switch valve is controlled to be turned off to stop filling when a temperature transmitted by the temperature sensor is lower than a control set value of the temperature control device, thus the occurrences of accidents are avoided.
Description
technical field [0001] The invention relates to a vacuum pumping system capable of preventing liquid chlorine from being poured backwards, and belongs to the field of filling dangerous liquefied chemicals. Background technique [0002] After the liquid chlorine tank car is filled, it is necessary to evacuate the liquid chlorine remaining in the liquid chlorine crane pipes, valves, etc. to avoid leakage and poisoning accidents. Therefore, liquid chlorine filling stations have corresponding evacuation devices. In practice, when valve failures or operating errors occur, liquid chlorine will enter the buffer tank through the valve. According to the filling speed, it takes 10 seconds for the liquid chlorine to fill the buffer tank (800L), and then the liquid chlorine enters the pumping pipeline. Since most of the evacuation pipes are plastic composite pipes, under the action of gravity and low temperature, the composite pipes are easy to break, resulting in chlorine leakage. Ev...
