There are extremely many types of organic waste liquids in waste liquid burners. Today, we will sort them out for you by referring to relevant information.
Organic waste liquids are divided into 3 categories based on their chemical composition:
① Halogen-free organic waste liquid. The organic compounds in this type of waste liquid only contain C, H, O, and sometimes S. When the waste liquid contains less water, it is combustible and can be used as fuel (such as waste organic solvents). The combustion products are CO2, H2O and SO2. The heat generated by combustion can be recovered through the boiler or waste boiler.
② Halogen-containing organic waste liquid. Organic compounds in the waste liquid include CC4, vinyl chloride, methyl bromide, etc. The calorific value of waste liquid depends on the halogen content. During incineration, whether auxiliary fuel is needed is determined based on its calorific value. After the waste liquid is oxidized in the incinerator, elemental halogen or hydrogen halide (HF, HCl, HBr, etc.) will be produced, which can be removed or recycled as needed.
③ High-salt organic liquid. This type of waste liquid containing high concentrations of inorganic salts or organic salts will produce molten salts after combustion. Therefore, the selection of refractory materials, combustion temperature and determination of residence time will become the main considerations during design. Since this type of waste liquid usually The calorific value is low and auxiliary fuel is required to achieve complete combustion.
The general process of organic waste incineration treatment includes several stages such as high-temperature incineration at the pre-batch surface, waste heat recovery and tail gas treatment.
Pretreatment mainly includes the passage of accumulation, shrinkage of banana hair, adjustment of viscosity, etc. Its purpose is to provide optimal conditions for the subsequent incineration process. The properties of the liquid are different: The process flow of incineration treatment of organic waste liquid with very different COD value can be directly sent to the incinerator burner for incineration treatment. For waste with high calorific value and low calorific value, Burning of very high organic waste liquids For organic waste liquids with relatively high moisture content, the liquid can be evaporated first, and auxiliary fuel can be added to help the waste liquid be incinerated.
The burner manufacturer reminds you: when the waste liquid does not contain harmful low-boiling point organic matter, the method of direct concentration of high-temperature flue gas can be considered, and then incineration can be carried out after concentration. However, for organic waste liquids containing harmful low-boiling point components, indirect heating concentration method should be used.
