Self-cleaning static rotary pyrolysis device

Abstract

An embodiment of the invention provides a self-cleaning type static rotary pyrolysis device. The self-cleaning type static rotary pyrolysis device comprises a feed port, a heating pipe, a chain plate, a driving wheel, a driven wheel, a coke cleaning wheel, a scraper coke extractor, a scraper tar extractor, a partition plate, a coke outlet, a pyrolysis gas outlet and a tar outlet. When the device runs, materials fall into the left side of the chain plate from the feed port, and the chain plate drives the materials to move from left to right; in a moving process, the heating pipe above the chain plate continuously heats the materials, so organic components of the materials are heated and decomposed; generated pyrolysis gas is discharged from the pyrolysis gas outlet; generated wall-adhered coke blocks are continuously cleaned by the coke cleaning wheel which is propped against the outer wall of the lower side of the chain plate, fall into the scraper coke extractor below the coke cleaning wheel and are conveyed to a coke outlet for discharging; and generated tar falls into the scraper tar extractor below the chain plate under the action of gravity and is conveyed to a tar outlet for discharging. The self-cleaning type static rotary pyrolysis device is simple and compact in structural design, simple to clean and maintain, high in automation degree, high in decoking effect, efficient and stable to use.

Description

technical field [0001] The invention belongs to the technical field of organic waste treatment and utilization, in particular to a self-cleaning static rotary pyrolysis device. Background technique [0002] Organic solid waste such as sludge and oil sludge is a large amount of organic waste generated in production and life, with complex composition, usually high water content, high oil content and contains a large number of harmful components, and has the characteristics of resource and environmental hazards. It is necessary to develop an efficient treatment and utilization method for this kind of solid waste to achieve harmless treatment and effectively recover the available resources in its components. Traditional methods mainly use incineration and sanitary landfill to dispose of organic solid waste such as sludge and oil sludge, which has a low resource output rate and the risk of secondary pollution. The pyrolysis method heats the organic solid waste under anaerobic or...
