Problems solved by technology

However, there are two methods for the oil-water phase separation of the waste emulsion explosives: one is to separate the water and oil of the emulsion explosives by stirring and heating. Good oil-water phase separation effect; the second is to directly put it in the water phase tank and make it demulsify and separate water and oil in the environment of high-concentration ammonium nitrate solution. , the oil phase material floats on the water phase solution and easily adheres to the wall of the heating tube, which poses a safety risk

Abstract

The invention discloses a treatment method for recycling waste emulsion explosives. The steps of the method are as follows: S1: add waste emulsion explosives and water to a separation device, and heat the waste emulsion explosives through a heating cycle system; S2: add Demulsifier, stirring and demulsifying the material at the same time; S3: After the demulsification is completed, the separation device is used to separate the waste material matrix and the water phase; S4: The water phase in the S3 is transported to the water phase preparation tank for demulsification. Preparation of water phase; S5: use the waste matrix in S3 as the raw material for ammonium oil explosives, or add it and normal matrix into the waste sensitizer, add foaming agent and accelerator to sensitize again, and re-sensitize Get qualified emulsion explosives. The treatment method of the invention has the advantages of good oil-water separation effect, simple operation and the like.

Description

technical field [0001] The invention relates to the technical field of emulsion explosives, in particular to a treatment method for recycling waste materials of emulsion explosives. Background technique [0002] The treatment method for the reuse of the waste emulsion explosives is to further demulsify the waste emulsion explosives to separate the oil and water, and then carry out subsequent treatment. However, there are two methods for the oil-water phase separation of the waste emulsion explosives: one is to separate the water and oil of the emulsion explosives by stirring and heating. Good oil-water phase separation effect; the second is to directly put it in the water phase tank and make it demulsify and separate water and oil in the environment of high-concentration ammonium nitrate solution. , the oil phase material floats on the water phase solution and is easy to adhere to the wall of the heating tube, which poses a safety risk.
