NOx incinerator is a kind of incinerator designed to reduce the NOx concentration in the incineration exhaust. It is through improving the layout of the incinerator to reduce the oxygen concentration in the flue gas, the very high temperature of the falling flame, and the retention time of the contracting gas in the high temperature area, so as to reach the goal of the low NOx concentration in the exhaust gas.
The basic principle of an incinerator designed to reduce the NOx concentration in the incineration exhaust gas is to improve the layout of the incinerator to reduce the oxygen concentration in the flue gas, the very high temperature of the falling flame, and the retention time of the contracting gas in the high temperature area, so as to reach the target of the NOx concentration in the low exhaust gas. There are three types of low nitrogen oxide incinerator: 1) the mixture of excited type, the rapid mixture of fuel and atmosphere causes a conical thin flame, which shrinks the gas retention time; 2) the self recycling type, in which the combustion gas is reincarnated, in the recycling area, when the oxygen concentration is low, the fuel vaporizes to excite gasification, and with the fall of the rear incineration temperature, the nitrogen decreases Oxide concentration; 3. According to the flame type, the fuel oil spout from the incinerator is spray into several spray to cause a few small fires to heat, and the temperature of the flame will be lowered due to the progress of the heat release machine, and the gas will remain in the high temperature area.
(1) The affinity of carbon monoxide, carbon monoxide and heme is 210 times larger than that of oxygen and heme. Therefore, carbon monoxide will invade the human body and quickly connect with heme in the blood to form carbon monoxide heme. When carbon monoxide heme accounts for 10% of the total heme in the human body, it will bring adverse effects on people's learning and things; when it accounts for 20%, it will cause headaches, dizziness and poisoning; when it accounts for 60% - 65%, people will die. Therefore, too high carbon monoxide content in the atmosphere is very risky for human body. When the content reaches 10 parts per million, people will be chronically poisoned if they touch it forever; when the content reaches 1%, people can only live for 2 minutes and die. The daily average concentration limit of CO in China's atmosphere should not be higher than 4.0 mg / m3.
(2) There are more than 200 kinds of organic factors in the hydrocarbon emission of hydrocarbon vehicles. It's not clear what the effects of hydrocarbons on human health are. However, one-sided organic factors have been proved to be carcinogenic materials, such as benzene and other polycyclic aromatic hydrocarbon species. These carcinogenic materials have the effect of accumulating and accumulating forever in human body, so it is important to master the emission of volatile organic compounds. In addition, the hydrocarbons and nitrogen oxides emitted by automobiles will further generate photochemical feedback under the use of strong sunlight, resulting in toxic photochemical smog. Photochemical pollution is a sign that the exhaust gas from automobile becomes extremely intense atmospheric pollution, which brings the risk of tension to human health and ecological conditions. When it is tense, people will die.
(3) The general term for nitrogen oxide, which contains more nitrogen oxide and less nitrogen dioxide in automobile exhaust. According to the review of medical research, high concentration of nitric oxide will cause paralysis and spasm of the human central nervous system. Although the low concentration of no is not toxic, nitrogen dioxide is a very toxic gas. It is a reddish brown irritant gas. When the content reaches 5 parts per million, it will smell a very strong odor, which is very dangerous to the human respiratory system and immune effect. If the concentration of nitrogen dioxide is over 100 parts per million, and people only have 01.5-1 hours in this, they will die of pulmonary edema. In addition, nitrogen oxide is also an important condition for photochemical smog, which is the main pollutant for Beijing to master the emission of flexible vehicles. According to the requirements of the fourth paragraph of Article 7 of the law of the people's Republic of China on the prevention and control of atmospheric pollution, "where there is a scale of discharge of atmospheric pollution to an area with a scale of discharge, the scale of discharge shall be implemented" and the notice, the following 19 high emission passenger cars in Beijing forever will also be subject to the same restrictions as the vehicles in this city. The vehicles that will always be stationed in Beijing will be able to go to any nearby flexible vehicle testing field entrusted by the environmental protection department to carry out emission testing. If they reach the designated emission standard, they can be issued with "environmental protection mark". According to the "environmental protection mark" and related procedures you have received, go to the traffic management department of the public security to solve the problem of "Beijing entry permit". Vehicles receiving the "green environmental protection mark" will not be restricted.
