Description

A kind of harmless waste incineration treatment process

technical field

The invention relates to the technical field of harmless waste treatment, in particular to a harmless waste incineration treatment process.

Background technique

With the rapid urbanization and economic growth in my country, the population of major cities in China has rapidly expanded, and the amount of urban waste generated in major cities is huge, and the problem of garbage is becoming more and more prominent. At present, the most prominent and urgent contradiction facing the harmless treatment of urban waste in my country is the lack of construction capacity of treatment facilities. At present, cities in my country mainly dispose of garbage by landfill, and all urban garbage is faced with the problem of no land to bury. On the other hand, landfills have caused serious pollution of groundwater sources and soil, increasing the pressure on the environment and ecology, and the siege of garbage has also affected the further expansion and development of the city. Strengthening the capacity building of harmless waste treatment facilities is the most important task at present and in the future.

Incineration is the most promising method to deal with municipal waste according to the principle of "three modernizations", but the construction and long-term operation of waste incineration plants bring about secondary pollution problems, especially the waste generated during the incineration process. Dioxin pollution has attracted worldwide attention. According to statistics, on a global scale, dioxins emitted by waste incinerators account for about 10%-40% of the total dioxin emissions. The Chinese government established the dioxin emission standard of 1ngTEQ/m3 and implemented it nationwide from June 1, 2003, while the dioxin emission standard of developed countries such as Japan and Switzerland is 0.1ngTEQ/m3. Therefore, in the process of waste incineration, effective measures must be taken to strictly control the generation and emission of dioxins.

It is generally believed that the combustion of organic matter in the presence of chlorine and metal elements will produce dioxins. Through analysis, it is found that municipal solid waste contains a large amount of organic chlorides (such as polyvinyl chloride plastics, chlorobenzene, etc.) and inorganic chlorides (such as sodium chloride, magnesium chloride, etc.), of which the content of organic substances reaches 20%-50%, This leads to the largest amount of dioxins produced in the process of municipal solid waste incineration, followed by the incineration of toxic and hazardous wastes. Dioxin production pathways can be summarized into two aspects: on the one hand, the presence of chlorine sources (such as PVC, chlorine, HCl, etc.), dioxin precursors and reaction catalysts (Cu, Fe), when the furnace temperature is lower than 850 ℃ , when the residence time is less than 2s, some organic matter will react with molecular chlorine or chlorine free radicals to generate dioxins; on the other hand, during the combustion process and at the end of the incineration, dioxins are regenerated due to changes in combustion conditions. For example, when the garbage is not fully burned, there are too many unburned substances in the flue gas. When encountering an appropriate amount of transition metals, especially copper, in a low temperature environment of 300-500 ° C, the dioxins that are decomposed by high temperature combustion will be decomposed. regenerate.

At present, the flue gas after incineration contains a small amount of dioxin, and the treatment methods are as follows:

(1) Reduce the residence time of flue gas in the concentration range of 200-350 °C to reduce the re-generation of dioxins;

(2) The use of fuel oil or gas to further burn the flue gas;

(3) Reduce the exhaust gas temperature, so that the dioxins in the gas phase are transferred to the ash phase, and then the dioxins are removed by a bag filter;

(4) The flue gas passes through the electrostatic precipitator, and the temperature is kept at 240-280℃;

(5) Use slaked lime or lime slurry to neutralize acid gas components, and use in combination with bag dust removal system to effectively remove dioxins;

(6) Spray activated carbon or porous adsorbent into the flue gas for adsorption, and then use a bag filter to capture;

(7) The wet dust collector is used to remove dioxins in the waste incineration fluidized bed boiler system.

At present, a large number of small incinerators are used to treat rural domestic waste and urban domestic waste. Most of the incinerators do not have dioxin control facilities, resulting in excessive dioxin emissions and serious environmental pollution.

Therefore, there is an urgent need to develop a harmless waste treatment process, which can solve the technical problem of dioxin pollution with low cost and high efficiency.
