Description

TECHNICAL FIELD

[0001] The utility model relates to incineration waste liquid technical field, specifically related to a kind of incineration waste liquid pretreatment system. BACKGROUND

[0002] Industrial organic waste liquid (waste water) generally contains flammable, toxic, corrosive and other dangerous characteristics of organic matter, such as not properly handled and directly or indirectly discharged into the environment, which can cause serious harm to human health and the environment. In order to solve this problem, the usual organic waste liquid treatment ideas are harmlessness, reduction, and resource utilization.

[0003] Incineration is a kind of technology by pyrolysis treatment, which can realize waste harmless, reduction and resource utilization. The basic principle of organic waste liquid incineration is that the organic waste liquid to be treated and excess air (oxygen) are oxidized and combusted in the incinerator, and the harmful substances can be destroyed at a high temperature of 1100℃. Incineration treatment technology can maximize the incineration of organic waste liquid, achieve the purpose of changing the incinerated material into harmless material and minimizing the volume, and can effectively control the generation of new pollutants and avoid secondary pollution. At the same time, the heat generated by organic waste liquid incineration can also be recycled. However, there are usually a small amount of solid impurities in organic waste liquid, such as direct entry into the atomizing lance of the incineration system, which is easy to cause blockage and wear of the atomizing lance and frequent replacement of the lance, so that the processing efficiency of the incineration system is low. In addition, for multiple streams of waste liquid, it is necessary to adjust according to the calorific value, halogen content and other indicators to make it reach the incineration index before incineration treatment. Therefore, the incineration waste liquid pretreatment has important influence on whether the incineration system can run efficiently. SUMMARY
