As shown in fig. 1, the embodiment of the present invention provides a conveying system for low flash point, volatile and flammable liquid-diethylamine, comprising an underground storage tank 6 for storing diethylamine, further comprising a U-shaped pipeline 1, a pneumatic diaphragm pump 2 and a controller, wherein one end of the U-shaped pipeline 1 is connected to the outlet end of the underground storage tank 6, the other end is connected to the pneumatic diaphragm pump 2, the U-shaped pipeline 1 is used as the inlet pipe of the pneumatic diaphragm pump 2, the other end of the pneumatic diaphragm pump 2 is connected to a stainless steel wire hose 3, the stainless steel wire hose 3 is used as the outlet pipe of the pneumatic diaphragm pump 2, and the connection between the stainless steel wire hose 3 and the pneumatic diaphragm pump 2 is the outlet of the pneumatic diaphragm pump 2; a pneumatic pressure relief valve 5 is connected between the U-shaped pipeline 1 and the stainless steel wire hose 3, and the pneumatic pressure relief valve 5 is close to the pneumatic diaphragm pump 2; the controller is electrically connected with the pneumatic pressure relief valve 5 and the pneumatic diaphragm pump 2. In addition, be equipped with pneumatic bleeder valve 4 on the stainless steel wire hose 3, pneumatic bleeder valve 4 with controller electric connection.
Specifically, pneumatic relief valve 5 is connected pneumatic diaphragm pump 2's inlet pipe with the discharge gate, opens through the controller with pneumatic bleeder valve 4 and pneumatic relief valve 5 and pneumatic diaphragm pump 2 and stops to carry out interlocking control. The diethylamine was transported to the production plant using an air operated diaphragm pump 2. When conveying the diethylamine, starting the pneumatic diaphragm pump 2, simultaneously automatically closing the pneumatic pressure release valve 5 by the controller, opening the pneumatic discharge valve 4, and conveying the diethylamine to a production workshop for production and use; when the pump is stopped, the controller controls the pneumatic discharge valve 4 to be automatically closed, the pneumatic pressure relief valve 5 is automatically opened, and the pressure in the discharge pipe of the pneumatic diaphragm pump 2 is discharged. Meanwhile, the material inlet and outlet pipe of the pneumatic diaphragm pump 2 is communicated, so that the problem of gasification and pressure rise of low flash point, volatile and flammable liquid is effectively solved, and the problem that the diaphragm pump cannot be started due to the fact that the pressure in the pump cavity is higher than the pressure of an air source when the diaphragm pump is started again is solved. The gasification and pressure rise problems of the low-flash-point, volatile and flammable liquid are more prominent in summer. In addition, partial liquid is stored in the U-shaped pipeline 1, so that the condition that the pneumatic diaphragm pump 2 cannot normally work due to too large suction process when being restarted is avoided, the adverse effect of diethylamine gasification on the conveying of the pneumatic diaphragm pump 2 is eliminated, and the problem of stability of diethylamine liquid conveying is solved. The utility model discloses a positive displacement transport mode relies on the extrusion of diaphragm outside extruding the diethylamine pump.
