Pressurizing reverse-flow type organic garbage gasification furnace

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.
