Description

TECHNICAL FIELD

[0001] The utility model belongs to waste fuel treatment equipment or device technical field, more particularly to a waste liquid treatment system. BACKGROUND

[0002] In field combat scenarios, the operation of various military equipment depends on sufficient fuel supply. Fuels such as unsymmetrical dimethylhydrazine have excellent combustion performance and are widely used in the military field, especially in space launch, missile propulsion, etc. However, after the completion of the combat mission, a certain amount of residual waste fuel will be generated. These residual waste fuels such as unsymmetrical dimethylhydrazine are toxic and flammable and explosive, and if not properly handled, not only will it cause serious pollution to the environment, but also may cause safety accidents, threatening the safety of combat personnel and surrounding facilities.

[0003] Currently, there are many problems in the treatment of residual waste fuel in field combat. Traditional treatment methods, such as simple open dumping or burying, will cause soil and water pollution, and cannot fundamentally eliminate the hazards of waste fuel. Some simple combustion equipment for incineration treatment can reduce the amount of waste fuel to some extent, but due to the simplicity of the equipment, it is difficult to ensure complete combustion, and a large amount of harmful gas will be emitted into the atmosphere, causing serious damage to air quality, and also not meeting the increasingly stringent environmental standards. In addition, the field combat environment is complex and changeable, and the existing treatment equipment is difficult to adapt to harsh natural conditions. In low temperature, high altitude, strong wind and other environments, the performance of the equipment will be greatly reduced, and even cannot work normally.

[0004] With the diversification of military operations and the continuous improvement of environmental protection requirements, it is urgent to develop a high-efficiency incineration technology and equipment specially for residual unsymmetrical dimethylhydrazine and other waste fuels in field combat. This technology needs to have the ability to operate stably in complex field environment, can realize complete combustion of waste fuel, reduce harmful gas emission, and is simple, safe and reliable to operate, in order to meet the needs of rapid and efficient treatment of waste fuel in field combat, reduce the risk of environmental pollution, and ensure the smooth progress of military operations and the ecological safety of combat areas.
