Reactor and method for gasifying and/or melting materials

Abstract

A reactor used for gasifying and / or melting feed materials comprises a feed section, a pyrolysis section, gas feed devices, and a melting and super heating section. A reactor comprises a feed section (1) having an opening (2) for the feed materials; a pyrolysis section (8) connected to the preceding section to expand the cross-section so that a debris cone (9) of the feed materials is formed; gas feed devices (10) which open out into the plane of the expanded cross-section in the pyrolysis section and feed hot gases to the debris cone; a melting and super heating section (14) connected to the pyrolysis section; upper feeding devices (15) for introducing an energy-rich medium into the melting and super heating section; a reaction section (20) connected to the melting and super heating section and containing gas suction devices (21) for removing excess gases; a hearth (25) with a tap (27) for collecting and deviating metal melts and slag melts; and lower feeding devices for introducing an energy-rich medium to prevent solidification of the melts. An independent claim is also included for a process for carrying out gasifying and / or melting of feed materials. Preferred Features: A pre-tempering section (5) is arranged between the feed section and the pyrolysis section and has double walls to create a hollow chamber (6) into which a heat transfer medium is fed.

Description

technical field [0001] The invention relates to a reactor and a method for gasifying and / or melting substances, in particular the invention relates to the material and energy utilization of any waste, for example waste of mainly organic components, but also to the material utilization and utilization of special waste energy utilization. The reactor and the method according to the invention are also suitable for packing materials of any composition, or for obtaining energy by feeding in organic matter. Background technique [0002] Attempts have long been made to thermally remove various litter and other substances. In addition to the combustion method, various gasification methods are known, all of which are aimed at achieving a less polluting environment with harmful substances and reducing the costs of handling the charge and of the gases produced by the process. However, the known methods are characterized by high costs and technical difficulties, so that the removal co...

Problems solved by technology

However, this circulation principle has the following disadvantages: the gas rising in the blast furnace is cooled in the waste dump, and thus emerges in the exhaust area, in the circulation gas line and in the gas jet compressor required to lead back the circulation gas Phenomenon in which pyrolysis products condense and thus interfere with the function of the circulating gas furnace

Dust and small waste particles are necessarily discharged during the venting of the circulating gas of the prior art, which, together with condensed pyrolysis products, lead to difficult-to-remove deposits inside the common circulation guide

In addition, the waste heap can only be heated relatively slowly by the rising circulating gas, so that when gasifying waste with a high plastic content, it will stick and adhere to the furnace wall, which may lead to a complete blockage of the furnace
