Organic waste pyrolysis oil and gas purification recycling technology and purification recycling device

Abstract

The invention discloses an organic waste pyrolysis oil and gas purification recycling technology and device. High-temperature pyrolysis oil and gas enter multi-level cooling purification separators through a gas phase flow guiding pipes. The cooling purification separators are communicated through gas phase decompression flow guiding pipes and liquid phase flow guiding pipes. After the high-temperature pyrolysis oil and gas is cooled and adsorbed by water contained inside the multi-level purification separators, the separated noncondensable gas is collected from the upper end of the tail-level cooling purification separator, wax oil is collected from a wax oil outlet in the lower end of each level cooling purification separator, fuel oil is collected from a fuel oil outlet of the last-level cooling purification separator, sedimented impurities and liquid are discharged from a sewage draining exit at the bottom of the last-level cooling purification separator. The organic waste pyrolysis oil and gas purification recycling technology and device have the advantages that liquid water is adopted as a cooling separation medium, and wax oil, fuel oil and noncondensable gas in oil gas are rapidly separated; the system can achieve safe production under the normal pressure through the gas phase decompression flow guiding pipes, and the problems that pressure building inside cooling purification separator cavities and gas resistance inside the liquid phase flow guiding pipelines are solved.

Description

Technical field [0001] The invention relates to an organic waste pyrolysis oil and gas purification recovery device, in particular to quickly separate and collect wax oil, fuel oil and non-condensable gas contained in high-temperature oil and gas under normal pressure. Background technique [0002] The organic solid waste is heated in a cracking furnace under normal pressure and anoxic state to break the chain of the polyolefin macromolecules in the organic waste, cracked into small molecular substances and precipitated, after entering the system in a gas state, most of them are converted into a liquid state , That is, pyrolysis oil, and the gas that cannot be liquefied is non-condensable gas. For a long time, the efficient and safe collection of pyrolysis oil and gas of organic waste has been a major problem that plagued the organic waste treatment industry. People usually use the following methods, one of which is: in the pyrolysis process of waste tires, rubber, plastics, etc...
