Hearth of household garbage incinerator based on grate furnace

Abstract

The invention discloses a hearth of a household garbage incinerator based on a grate furnace. The hearth comprises a fire grate as well as a face arch, a rear arch and left and right side walls above the fire grate, wherein the hearth is sequentially provided with a drying region, a combustion region and a burnout region from top to bottom in a region above the fire grate; the face arch is arranged above the drying region, the rear arch is arranged above the combustion region and the burnout region, the fire grate, the face arch, the rear arch and the side wall of the hearth jointly enclose combustion space of garbage, a garbage inlet is formed in the front end of the combustion space, an outlet flue is arranged at the connection of the face and rear arches at the top of the combustion space, a slag fall opening is formed in the bottom of the combustion space, and a guide wall which transversely passes through the hearth is further arranged between the left side wall and the right side walls. According to the hearth disclosed by the invention, low heat value and high moisture household garbage can fully combust, so that gas in the hearth fully combusts and stays, the content of pollutants in smoke is reduced, excessive oxygen required by combustion is controlled, the gross smoke is reduced, and the project investment and operating cost are lowered.

Description

technical field [0001] The invention belongs to the field of incinerators, and in particular relates to a hearth of a domestic waste incinerator based on a grate furnace. Background technique [0002] With the rapid development of the national economy and the acceleration of the urbanization process, people's living standards are improving day by day, and the amount of municipal solid waste generated is increasing; High-concentration leachate and a large amount of harmful gas are very serious to environmental pollution, and at the same time need to occupy a large amount of land resources. Incineration treatment will become the main way of waste disposal. It can not only get rid of the dependence on a large amount of land resources, but also meet the dual requirements of environmental protection and resource utilization, and also conform to the national policy of domestic waste reduction, harmlessness and resource utilization. . [0003] In recent years, with the encouragem...
