The invention provides a safety sampling device for a nitrate adhesive. The safety sampling device comprises a lifting film evaporator, a separator and a finished product tank; the lifting film evaporator is sequentially connected with the separator and the finished product tank through a pipeline, is also connected with a previous process through a pneumatic valve I and performs material discharge through a pneumatic valve 2; a pneumatic valve V7 is arranged on the pipeline through which the separator is connected with the finished product tank; the separator is communicated with a vacuum; the finished product tank is connected with a vacuum through a pneumatic valve V8, is also communicated with the atmosphere through a pneumatic valve V9 and performs material discharge through a pneumatic valve V10. The safety sampling device further comprises a first sampling tank, the first sampling tank is connected with the separator through a pneumatic valve V3, materials in the first samplingtank are discharged through a pneumatic valve V4, the first sampling tank is communicated with a vacuum through a pneumatic valve V5 and a pneumatic valve V14 and is also communicated with compressedair through the pneumatic valve V5 and the pneumatic valve V15, and a pneumatic control device controls the opening or the closing of all the pneumatic valves. The safety sampling device provided by the invention can realize remote operation and safety sampling.
Description
technical field [0001] The invention relates to the technical field of organic synthesis, in particular to a nitrate binder safety sampling device. Background technique [0002] The mixed nitrate is a mixture of nitroglycerin (NG) and 1,2,4-butanetriol trinitrate (BTTN), and the nitrate binder is a nitrate plasticized polyether energetic binder. [0003] The production process of the continuous production line of mixed nitrates uses compressed air to press mixed acids (nitric acid and sulfuric acid) and mixed alcohols (glycerol and butanetriol) into the continuous injection pipeline nitration reactor for nitration reaction, and the mixed nitrates obtained by the reaction and excess The acid is separated in the ester separator, and then the nitrate enters the water washing tower and is washed with cold water, hot water, and hot alkaline water until the pH is ≤0.01%, and the product mixed nitrate is sent to the energetic adhesive preparation process. [0004] Since mixed nitr...
