A kind of jacketed reactor for alkaline hydrolysis of waste tnt

Abstract

The invention discloses a sleeve-type reactor for scrapped TNT (trinitrotoluene) alkaline hydrolysis. The sleeve-type reactor comprises a sleeve-type reactor body mounted on a supporting frame, the sleeve-type reactor body comprises a plurality of unit sleeve-type reactors, the unit sleeve-type reactors comprise heat insulation pipes, alkaline hydrolysis reaction pipes are arranged in the heat insulation pipes, alkali liquor injection pipes are embedded into the alkaline hydrolysis reaction pipes, the heat insulation pipes between two adjacent unit sleeve-type reactors are connected through heat insulation pipe flanges, the alkali liquor injection pipe of the previous unit sleeve-type reactor is connected with the alkali liquor injection pipe of the next unit sleeve-type reactor through aU-shaped pipe in a threaded manner, the alkaline hydrolysis reaction pipes are connected through alkali liquor pipes coaxially arranged in the U-shaped pipes, a TNT feeding port is formed in the upperend of the alkaline hydrolysis reaction pipe of the first unit sleeve-type reactor, and a TNT discharging port is formed in the lower end of the alkaline hydrolysis reaction pipe of the final unit sleeve-type reactor. According to the sleeve-type reactor, continuous, safe, efficient and environment-friendly running of TNT alkaline hydrolysis is achieved, and the treatment efficiency of scrapped TNT explosives is improved.

Description

Technical field [0001] The invention relates to the technical field of scrapped TNT alkaline hydrolysis, in particular to a sleeve-type reactor for scrapped TNT alkaline hydrolysis. Background technique [0002] my country’s military mainly uses high-energy explosives such as TNT, DNT (Dinitrotoluene), RDX (RDX), Octogen (HMX) and Nitrocellulose (NC), among which TNT is the most used. Nowadays, the usual method of disposal of discarded TNT explosives is incineration, which not only wastes resources, but also produces a large amount of high-concentration polluted exhaust gas and solid combustion residues during incineration, which will harm humans and ecology with air flow, rain or soil erosion. surroundings. In addition, there are certain risks in the incineration process. From a long-term perspective, resource utilization is the best and most effective way to dispose of scrapped TNT explosives. At present, the disposal methods for resource utilization include physical and che...

AI Technical Summary

Problems solved by technology

At present, the alkali hydrolysis reactor for waste TNT explosives is a sequential batch reaction, and the treatment efficiency is relatively low because the reactor cannot be operated continuously

TNT is a high-energy compound, which will release a large amount of heat during the alkali hydrolysis reaction, and the heat release is rapid, which makes it difficult to control the temperature of the reactor, and often requires rapid cooling, which seriously threatens the safety of operators.
