Problems solved by technology
The traditional solid hazardous waste treatment is relatively extensive. Usually, glass bottles are directly crushed and then directly used as cement raw materials for incineration. Rubber bottle caps cause the overall properties of hazardous waste incinerated in the kiln to be uneven, making the overall impurity rate and moisture content of cement raw materials uncontrollable, resulting in poor quality of cement raw materials, which will affect the raw material grinding capacity to a certain extent (reduced system output, increased power consumption, frequent equipment failures, etc.) may lead to fluctuations in the quality of cement clinker after firing; and because the nature of the waste liquid is relatively complex, it not only has problems of explosion and flammability, but also has different The waste liquids are prone to interact with each other to produce flammable gas, and there is a safety hazard of explosion.

The invention belongs to the field of solid hazardous waste treatment, and specifically discloses a pretreatment method for solid inorganic hazardous waste, including the following steps: step 1, pre-sorting; step 2, transportation; step 3, crushing; step 4, separation. The invention separates the waste liquid in the glass bottle from the broken glass bottle, and can also separate the bottle cap from the glass, so as to realize the refinement of the glass bottle broken wind, and make the impurity rate and water content of the hazardous waste after treatment, etc. The indicators meet the requirements of raw materials for cement kiln firing into the kiln to ensure the quality of the fired cement.
Description
Technical field [0001] The present invention relates to the field of solidular hazardous waste treatment, and specific to pretreatment methods of solid-state inorganic hazardous waste. Background technique [0002] my country's current hazardous waste (distant waste) is mainly incinerated for building incinerans kilns and landfills, landfill, but these disposal methods are difficult to dispose of high, leakage risk, and difficult land acquisition. Cement kiln coordinated hazardous waste is an emerging hazardous waste disposal technology, and reused some of the past, it can only incinerate and landfill, which achieves resource utilization and saving costs. [0003] The RDM production line (also known as solid raw material production line) is a second-stage crushing of various types of solid, hard inorganic substances, and removing impurities, and finally obtain solid products that meet the requirements of cement kiln, the raw material is mainly a pharmaceutical glass bottle. The t...
