Gasification and incineration method of moving grate gasification and incineration integrated furnace

Abstract

The invention provides a gasification and incineration method of a moving grate gasification and incineration integrated furnace. A first feeding device, a hearth, a lower moving grate arranged belowthe hearth and a partition plate used for separating the hearth into a lower portion gasification and combustion cavity and an upper portion combustion cavity are included. A flue gas flow through hole is formed in the position, close to a discharging port of the first feeding device, of the partition plate, and the discharging port of the first feeding device is located at the middle portion of the hearth. The lower portion gasification and combustion cavity and the flue gas flow through hole are provided with first air inlets and second air inlets correspondingly. The method includes the steps that the first feeding device is controlled to convey materials towards the interior of the hearth; the materials move towards an upper moving grate and absorb heat of flue gas flowing to the fluegas flow through hole, and drying and gasification are conducted; combustion supporting air is injected into the lower portion gasification and combustion cavity through the first air inlets so that the materials moving to the upper moving grate can be combusted; and combustion supporting air is injected into the glue gas flow through hole through the second air inlets so that the temperature of the flue gas in the flue gas flow through hole can be increased, and pyrolysis of tar in the flue gas can be achieved. The method has the beneficial effects that combustion is more sufficient, and efficiency is high.

Description

technical field [0001] The invention relates to the field of solid waste incineration treatment, in particular to a gasification and incineration method for a mobile furnace exhaust gasification and incineration integrated furnace. Background technique [0002] The existing waste treatment technologies mainly include incineration, sanitary landfill, composting, and waste recycling. Among the conventional waste treatment technologies, incineration has the advantages of obvious reduction effect, complete harmlessness, small land occupation, utilization of waste heat energy, and less secondary pollution, which meets the strategic requirements of my country's sustainable development. However, with the continuous improvement of environmental protection requirements at home and abroad, how to strengthen the control of secondary pollution is particularly important. Therefore, waste pyrolysis and gasification incineration technology is gradually pushed to the road of industrial app...

Problems solved by technology

[0005] In the prior art, there is a transitional slagging section between the gasifier and the embering furnace, and the transitional slagging section is provided with an openable and closable isolation door. Since the gasifier and the embering furnace are relatively independent, the slagging generated by material combustion The heat cannot be used mutually, which affects the efficiency of combustion
