Pressurizing reverse-flow type organic garbage gasification furnace

Abstract

The invention relates to the technical field of garbage treatment devices and provides a pressurizing reverse-flow type organic garbage gasification furnace. The pressurizing reverse-flow type organicgarbage gasification furnace comprises a gasification furnace body, a smoke refluxing device, a porous gas fetching device and an umbrella-type heat guiding device, and also comprises a smoke refluxing and cooling device. The gas refluxing and cooling device is arranged on t he top of the gasification furnace body, so that the drying speed of the garbage is accelerated, more carbon monoxide and hydrogen are generated, and the heat value of gasified gas is improved effectively. In addition, a plurality of gas fetching pipes are also arranged, so that gas is uniformly distributed in the furnacebody, and purity of discharged gas is prevented from being affected as the generated gas is left in the gasification furnace. The umbrella-type heat guiding device is arranged above the hearth of thegasification furnace, so that the temperature of a combustion layer can be kept in a high-temperature state. By refluxing the smoke in the organic garbage gasification furnace to a cooling and dehydrating device to remove water vapor in the smoke, the combustion value of the smoke is increased effectively.

Description

technical field [0001] The invention relates to the technical field of garbage treatment devices, in particular to a pressurized backflow type organic garbage gasifier. Background technique [0002] Garbage is solid waste generated in human daily life and production. Due to the large amount of discharge and complex and diverse components, it brings difficulties to treatment and utilization. One of the effective treatment methods is to pyrolyze gasification of garbage, pyrolysis Gasification is to heat garbage at high temperature in a closed room and convert it into synthetic gas, which is composed of carbon monoxide, carbon dioxide, methane and hydrogen. After filtering and chemical "cleaning", toxic particles and gases are removed, and then burned to generate energy or converted into methane, Fuel such as ethanol or synthetic diesel, waste gasification can quickly convert household waste into energy, and waste will turn from liability to asset, providing a clean energy sour...

Problems solved by technology

[0003] The pyrolysis and gasification of waste is completed in the organic waste gasification furnace. Part of the waste in the organic waste gasification furnace is added from the side wall of the gasification furnace. The waste is oxidized, reduced, pyrolyzed and dried in the furnace body. A thermochemical reaction process produces combustible gas. Since the top of the gasifier is sealed, it is difficult for the smoke generated in the furnace to rise, and there is a dead zone, and the drying speed of the garbage is very slow. At the same time, the smoke in the gasifier The water vapor in the gasifier is also not easy to dry. Secondly, the water vapor that has not been dried is easy to be discharged together with the flue gas, so that the water vapor content in the flue gas is relatively high. In addition, because the gasification furnace is usually high, when it is working, the furnace is full. Garbage, the back pressure of the air supply blower is large, which often leads to insufficient oxygen supply for garbage incineration, which makes it difficult to maintain the required high temperature in the cracking zone and reduction zone, the cracking and reduction of garbage is not complete, the speed is slow, and the tar content in the flue gas is large , these are not conducive to the gasification of garbage
