Abstract

The invention relates to a vibrating grate which is in a split structure with an upper layer and a lower layer; the grate at the lower layer is a fixed grate, is placed in a regular trapezoid by a plurality of trapezoidal stainless steel racks and is formed by fixedly connecting two ends of the fixed grate to the inner side of a grate loop; the grate at the upper layer is a movable grate, is placed in an inverted trapezoid by a plurality of trapezoidal stainless steel racks, is formed by fixedly connecting two ends of the movable grate to the inner side of a grate loop, and is connected and linked with a hydraulic power device; the racks of the grate at the lower layer are correspondingly occluded with the racks of the grate at the upper layer, and the transverse gap between the racks of the grates at the upper layer and the lower layer which are adjacent at an occlusion part is set to be 5-80mm; and the hydraulic power device is controlled by a PLC (Programmable Logic Controller) automatic control system to drive the grate at the upper layer to vibrate at the frequency of not larger than 200 times/minute. In the invention, coked clinker shale particles are discharged through vibration and extrusion, thus the aims of continuous gasification and power generation are achieved, and the vibrating grate is applicable to a continuous gasification and power generation technology in the biomass gasification reaction process.

Description

technical field [0001] The invention relates to a slagging system for a biomass gasification reaction chamber. Background technique [0002] Biomass gasification power generation has always been an important key issue in the field of biomass energy for human beings, and continuous operation of equipment and slag discharge have become an important step. Hours of uninterrupted operation, while timely discharge of ash, in order to achieve the purpose of continuous power generation and energy consumption. [0003] In the existing gasification reaction chamber slagging system, once coking and large particles of ash appear, the entire gasification reaction chamber will be shut down and the entire set of biomass gasification equipment will stop running; the coking and ash generated cannot be discharged smoothly and in time , and even manual slag removal is required. Contents of the invention [0004] In view of the above-mentioned problems in the prior art, the present inventio...
