MULTI-STAGE HYDRAULIC MECHANICAL GARBAGE INCINERATOR AND CONTROL METHOD THEREFOR

摘要

A multi-stage hydraulic mechanical garbage incinerator and a control method therefor. The garbage incinerator comprises a material-feeding inlet, a material-feeding grate, an incineration grate, a primary air supply system, and a secondary air supply system. The incineration grate is divided along the longitudinal direction into five units, where the units from the first unit (2) to the fourth unit (5) are standard units, and where the fifth unit (6) is an end extension unit, while each of the units (2, 3, 4, 5, and 6) consists of several sliding grate plates, flipping grate plates, and fixed grate plates. The five units divide the entire incineration grate along the longitudinal direction into a drying section, a combustion section, and a burnout section. Each grate plate of the incineration grate is driven along the horizontal direction by a shaft, and is supported in the horizontal direction on at least three positions by steel frames. The control method for the garbage incinerator comprises control methods for the air supply systems and for the incinerator grate plates. This is to improve the insufficiency in existing garbage incinerators and to increase the burnout rate of garbage incineration.
