Vertical waste incinerator using roller type grates

Abstract

The invention discloses a vertical waste incinerator using roller type grates, and relates to the technical field of municipal solid waste disposal equipment. The vertical waste incinerator comprises a vertical cylindrical incinerator body, a heat preservation layer and a metal framework, wherein the heat preservation layer and the metal framework are arranged on the periphery of the incinerator body. The vertical waste incinerator is structurally characterized in that two reburning flues, two first flue gas outlets and two flue gas discharging channels which are corresponding in position are sequentially formed in the side wall of the incinerator body from bottom to top, a feeding hole is formed in the upper part of the incinerator body, an arch-shaped capping is arranged at the top of the incinerator body, a vertical and upward second flue gas outlet is formed in the top of the arch-shaped capping, tower grate furnace bars are arranged in the center of the bottom of the incinerator body, a driving shaft is connected under the tower grate furnace bars, a slag outlet is formed under the incinerator body, an air inlet is formed in the side wall of the slag outlet, a combustion fire grate is arranged in the middle of the inner cavity of the incinerator body, and a drying fire grate is arranged near the feeding hole in the upper part of the inner cavity of the incinerator body. Compared with the prior art, the vertical waste incinerator has the advantages that the roller type fire grates are additionally arranged, the flue gas is layered and graded, and therefore continuous combustion and controllable combustion of the waste can be realized, and high-efficiency incineration of the household waste can be realized.

Description

technical field [0001] The invention relates to the technical field of urban domestic garbage treatment equipment, in particular to a vertical garbage incinerator using a roller grate. Background technique [0002] Waste incineration treatment is a new waste treatment method emerging in the last century. It is the most effective and thorough way to reduce the volume of urban domestic waste, make it harmless, and turn it into a resource. The garbage incinerator is the core equipment to realize the incineration of domestic garbage. In recent years, there are many types of waste incinerators, and some projects have been operated for a long time. However, with the successive introduction of relevant national and international standards, higher requirements will be put forward for the currently operating waste incineration system. Require. [0003] In the existing technology, the calorific value of domestic waste in most cities in my country is between 3000 kJ / kg~6000 kJ / kg, an...

Problems solved by technology

If an imported incinerator is used for incineration, not only the equipment cost is high, but the operating cost is high, and the quality of garbage incineration is difficult to maintain stability
