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

Embodiment 1

[0039] The treatment product is dinitrogen tetroxide waste gas 100wt%, and the fuel is kerosene:

[0040] During the processing operation, the air enters the furnace from the primary air inlet 17 and the secondary air inlet 3, the primary air coefficient is 0.96, the total air coefficient is controlled at 2.5, the ignition button is activated, the ignition port 1 is ignited, and the fuel nozzle 11 is sprayed. Combustion, the furnace starts to heat up. When the temperature of the temperature measuring port 6 of the furnace body reaches 600 ° C, dinitrogen tetroxide is introduced into the furnace from the processing gas inlet 16 and burns together with the fuel under the action of air, and the flame combustion is observed through the fire viewing hole. Turn the adjustment screw 13 appropriately to adjust the gap between the distribution plate 19 and the restrictor cylinder 20 to make the air distribution reasonable. At this time, open the secondary combustion nozzle in the middle...

Embodiment 2

[0042] Other conditions are the same as in Example 1, the concentration of the treated substance is changed to 80% dinitrogen tetroxide, the primary air coefficient is adjusted to be 0.74, the total air coefficient is 2.7, and the nitrogen dioxide content in the tail gas is 650ppm.

Embodiment 3

[0044] Other conditions are the same as embodiment 1, change the treatment substance concentration into 20% dinitrogen tetroxide, use aviation kerosene instead of fuel oil, adjust the primary air factor to be 0.80, and the total air factor is 2.9, sampling analysis, nitrogen dioxide content in the tail gas is 620ppm.

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...
