The invention provides an environment-friendly gasifier for self-processing dusty tar. The gasification furnace is provided with a plurality of nozzles, and the gasification furnace also includes a tar tank, a homogenizer and a first tar injection pump, and the tar tank is used to collect dusty tar from the entire gasification system including the gasification furnace; The homogenizer is connected to the outlet of the tar tank for grinding and stirring the dusty tar; the inlet of the first tar injection pump is connected to the homogenizer, and the outlet is connected to at least one of the nozzles for passing the dusty tar through At least one nozzle sprays into the gasifier. The present invention can return the dusty tar in the entire gasification system to the gasification furnace to participate in combustion by using a tar tank, a homogenizer and a tar injection pump, and realizes the recycling of the dusty tar. The self-processing dusty tar of the present invention is used The environmentally friendly gasifier effectively solves the pollution problem caused by the direct discharge of dusty tar in the prior art, and at the same time can improve energy utilization and turn waste into treasure.
Description
technical field [0001] The invention relates to the technical field of coal treatment, in particular to an environment-friendly gasifier for self-processing dusty tar. Background technique [0002] Many production processes in industrial production need to use gas, and more and more people use gas as energy in daily life. In order to meet people's demand for gas, a coal gasification device is usually used to gasify carbon-containing solid fuels such as coal, plastic, garbage, old paper, etc. to generate gas. [0003] Among them, the fixed-bed gasifier uses carbon dioxide / steam and oxygen as the gasification agent to convert block solid carbon-containing fuel into crude gas. Due to the mature and reliable technology, the one-time investment is small, the operation cost is low, and the construction The cycle is short and it is widely used at home and abroad. [0004] However, in the prior art, the fixed-bed gasifier has the function of carbonization, which will cause the oil...
