Organic solid waste semi-in-situ carbon sequestration gasification device and application thereof

Abstract

The invention belongs to the field of energy treatment and utilization of solid wastes, and particularly relates to an organic solid waste semi-in-situ carbon sequestration gasification device. The device comprises a gasification furnace body, a heat supply interlayer, a semi-in-situ catalyst placing net and a movable fire grate, wherein the gasification furnace body comprises a solid waste feeder, a carbon dioxide inlet, a combustible gas outlet, a catalyst replacement port, an ash outlet, an ash bin and the like; the heat supply interlayer is communicated with the hot air inlet and the hot air outlet; the organic solid waste is converted into combustible gas by controlling the furnace temperature and the carbon dioxide amount. The device is simple and ingenious in structure, high in gasification efficiency and stable in carbon dioxide fixation. Compared with an in-situ gasification catalytic device, carbon deposition and coverage caused by mixing of a catalyst and fed materials are avoided, compared with a two-stage gasification catalytic device, the investment cost can be reduced, the problems of slow natural degradation, incineration emission pollution and the like of organic solid waste can be effectively solved, the treatment efficiency of the organic solid waste is improved, and increase of carbon dioxide is effectively inhibited.

Description

technical field [0001] The invention belongs to the technical field of solid waste energy treatment and utilization, and in particular relates to a semi-in-situ carbon fixation gasification device for organic solid waste and its application. Background technique [0002] The treatment of organic solid waste is a problem that must be faced in social and economic development. Like solid biomass and plastics, the development and utilization of biomass energy can reduce fossil energy consumption. Due to the characteristics of strong plasticity, corrosion resistance, low price and the progress of related production technology, plastics have gradually become people's daily necessities in the past 50 years. Utilizing modern technology to achieve high-efficiency energy conversion of organic solid waste such as biomass and plastics is an important way to alleviate the contradiction between economic development, fossil energy consumption, and environmental pollution.
