Abstract

The invention discloses a waste pyrolysis and gasification treatment method for a tube furnace with rubbing-tooth grate bars. By adoption of the waste pyrolysis and gasification treatment method, waste can be stirred, loosened and scattered. The tube furnace with the rubbing-tooth grate bars comprises a working base plate, supporting frames, a thermal reaction pipe and a heating furnace. A fixed cross beam is fixed in the thermal reaction pipe. Movable grate bar sets and fixed grate bar sets are arranged on the fixed cross beam in the transverse direction. A driving device used for driving themovable grate bars to move in the longitudinal direction is mounted on the working base plate. The waste pyrolysis and gasification treatment method comprises the following steps that firstly, household waste is weighed and placed into a feeding port, and then the feeding port is sealed; secondly, the heating furnace is started, and the thermal reaction pipe is preheated; thirdly, a driving motoris started to convey the waste into the thermal reaction pipe for pyrolysis and gasification; and fourthly, the reaction temperature is controlled to 650-850 DEG C, so that the household waste is pyrolyzed and gasified in an oxygen-poor or oxygen-free condition, and the excess air coefficient is controlled within the range of 0-0.8.

Description

technical field [0001] The invention belongs to a pyrolysis incinerator grate, which is a main part of the pyrolysis incineration treatment of solid waste, and in particular relates to a rubbish pyrolysis gasification treatment method of a tooth rubbing grate tube furnace. Background technique [0002] The existing municipal solid waste treatment technologies mainly include incineration, landfill, composting, and waste sorting and recycling. Among the conventional technologies for waste disposal, incineration has the advantages of obvious reduction effect, complete harmlessness, small footprint, utilization of waste heat energy, and less secondary pollution, which meets the strategic requirements of my country's sustainable development. [0003] The most important component of a waste pyrolysis incinerator is the pyrolysis incinerator grate system. The pyrolysis incinerator grate system is mainly responsible for the transportation of garbage in the thermal reaction tube, wh...
