Burning furnace for treating unsyn dimethyl hydrazonium or/and dinitrogen tetra oxide and its application method

Abstract

The invention relates to treating dimazine or / and dinitrogen tetroxide combustion furnace. It includes heat resisting steel furnace body, burner, and chimney. The front of the furnace body is set burner joint and lighting up tuyere. The burner is fixed on the burner joint. Its middle is set secondary combustion nozzle joint. Its outer is set jacket. The front end jacket is set secondary air inlet. The secondary air inlet can reach the inner of the furnace. Its tail is set temperature measurement opening. The chimney is connected to the tail. Its upper and lower part is respectively connected to sensing hole and fire watching hole. The invention has the advantages of simple technique, convenient operation, safe and reliable, no secondary pollution, and the discharged tail gas is according with the country standard.

Description

technical field [0001] The invention belongs to a combustion furnace for treating unsymmetrical dimethylhydrazine or / and dinitrogen tetroxide by a combustion method and an application method thereof. Background technique [0002] With the continuous progress and development of society, human beings have realized the importance of protecting the natural environment. At present, my country has attached great importance to environmental protection. Environmental protection projects have become an extremely important research topic. After more than 20 years of development and improvement, environmental impact assessment has been completed. As a basic system of environmental management, my country's national economy will continue to maintain rapid development, and the task of controlling pollution, protecting the environment, preventing new pollution sources, and controlling environmental pollution and ecological damage is even more arduous. [0003] The unsymmetrical dimethylhydr...

Problems solved by technology

[0003] The unsymmetrical dimethylhydrazine and dinitrogen tetroxide used in launching satellites from China's satellite launch site are toxic and corrosive, and some waste liquid and waste gas will be generated during use. If these substances are directly discharged into the atmosphere, they will be harmful to humans, animals and plants. And the entire natural environment will produce serious pollution, and even cause the depletion or death of pollutants. On the other hand, due to its oxidative and flammable and explosive properties, when the concentration accumulates to a certain level, there is a hidden danger of explosion at any time. Therefore, , scientific researchers have researched and developed various treatment methods, such as catalytic combustion method, catalytic combustion method is to directly carry out catalytic oxidation reaction between the treated object and oxidant on the catalyst bed, because catalytic combustion is an exothermic reaction, the reaction is violent and emits The heat is concentrated and difficult to take out, which makes it difficult to control the temperature. Once the temperature is too high, the life of the catalyst will be shortened and deactivated. The regular replacement of the catalyst will increase the operating cost. Due to the unstable concentration of the treated material, the catalytic combustion is very difficult to control. In addition , the requirements for the material of the reactor are strict, which increases the operating cost of the treatment as a whole. In addition, there are various methods such as liquid absorption method and high-altitude discharge. These methods have the problems of huge equipment and need to be reprocessed. produce secondary pollution
