a 2: after the first operator finishes the installation of the drainage interface, connecting the drainage interface with a flow guide pipe of a drainage pipeline, and enabling a three-way ball valve to be in an open-close state;
a 3: the second operator connects the two shunt tubes with the quick connector respectively, connects the two shunt tubes with the material filling bag, and adjusts the valve of the quick connector to an opening state;
a 4: the third operator carries 3-5 groups of material filling bags and quick connectors for standby;
installing a drainage interface in the S3, wherein the method comprises the following steps:
b 1: if the leakage point is the tank containing point of the tank car, an operator I and an operator III hold the flow guide pipe and the first pressing piece, select proper positions, and install the first pressing piece at the leakage part of the tank wall to enable the leakage material to flow out from an opening side outlet of the three-way ball valve; if the leakage point is a pipeline of the tank car, an operator I and an operator III hold the flow guide pipe and the second pressing piece, select proper positions, and install the second pressing piece at the leakage part of the pipeline to enable the leaked materials to flow out from an opening side outlet of the three-way ball valve; if the leakage point is a valve of the tank car, one operator holds the flow guide pipe, and the other operator tightly ties the flow guide bag and the pipeline wall on the inner side of the valve by using the hose clamp, so that the leakage material flows out from an opening side outlet of the three-way ball valve;
b 2: the second operator connects the connected shunt tubes and the material filling bag with the closed side interface of the three-way ball valve, and adjusts the three-way ball valve switch after the connection is finished, so that the leaked materials enter the material filling bag through the shunt tubes;
b 3: the first operator and the third operator use the strapping tapes to strap and press the first pressing piece or the second pressing piece, and then follow-up operation of material conveying is carried out;
b 4: if the flow of the leaked materials is larger, the other flow dividing pipe is connected with a closing side interface of the three-way ball valve, and the three-way ball valve is adjusted to be opened at the two sides simultaneously, so that the double-pipeline transmission and rotation of the flow dividing pipes are realized;
b 5: when the material filling bag is full, the quick connector is closed, and a new material filling bag is replaced and connected so as to continue to implement material conveying and transferring operation.
2. The emergency transportation method of the leaked materials of the dangerous chemical tank truck according to claim 1, characterized in that: in S1, if the type of the leaking material is unknown, a personal protective device capable of responding to serious damage, a drainage port and a material filling bag made of two or more materials are provided so as to safely cope with the leakage treatment.
3. The emergency transportation method of the leaked materials of the dangerous chemical tank truck according to claim 1, characterized in that: in S2, before emergency treatment, a shield is performed, a water curtain is set to intercept and dilute the concentration of the toxic gas on site, and the diffusion direction is changed.
4. The emergency transportation method of the leaked materials of the dangerous chemical tank truck according to claim 1, characterized in that: in the S2, fire is controlled and extinguished through a water gun, and a liquid beach leaking on the site is covered through foam.
5. The emergency transportation method of the leaked materials of the dangerous chemical tank truck according to claim 1, characterized in that: before b1 in S3, observe the leakage opening of the leakage point, if the leakage opening is irregular, can't install the drainage interface, can't implement the emergent defeated commentaries on classics of leaking the material directly from the leakage opening, then under the condition of doing well protection and diluting the shield, choose for use the valve drainage interface, or choose for use the drainage pipeline that the bore is suitable, carry out the defeated commentaries on classics of material from the discharge gate valve that the tank car was taken certainly to slow down the leakage and threaten on-the-spot personnel and peripheral masses, reduce the environmental pollution that the leaked material caused.
6. The emergency transportation method of the leaked materials of the dangerous chemical tank truck according to claim 1, characterized in that: detecting leakage pressure between b1 and b2 in the S3, if the leakage pressure is small, trying to close the three-way ball valve, and observing whether leakage materials leak or not, and completing direct leakage stoppage of a leakage point; and if the leakage pressure is large or direct leakage stoppage cannot be completed, performing emergency conveying operation of the leaked materials to perform b2-b 5.
7. The emergency transportation method of the leaked materials of the dangerous chemical tank truck according to claim 1, characterized in that: the emergency material conveying and transferring device for the dangerous chemical tanker vehicle with the leaked materials disassembled in the S4 comprises the following steps:
c 1: closing the valves of the quick connector and the three-way ball valve, and sequentially disconnecting the quick connector from the flow dividing pipe and the flow guide pipe from the first drainage hole, the second drainage hole or the third drainage hole, so that the leaked material waste liquid in the flow dividing pipe and the flow guide pipe flows into the waste liquid barrel;
c 2: the operator brings each component of the dangerous chemical tank car leaked material emergency conveying device back to the decontamination station, detaches the sealing gasket, the first pressing piece or the second pressing piece, the strapping tape and the hose clamp, checks whether corrosion damage exists or not, and thoroughly decontaminates.
