Dip pipe feeding type organic solid waste molten iron bath gasification device

Abstract

The present invention discloses a dip pipe feeding type organic solid waste molten iron bath gasification device which comprises: a gasification furnace which contains a molten iron bath, wherein a slag bath floats on the molten iron bath; at least one dip pipe, wherein the lower end of any dip pipe is immersed in the molten iron bath, and the upper end of any dip pipe penetrates out of the gasification furnace and extends to the upper part of the gasification furnace; at least one feeding lock hopper, wherein one dip pipe corresponds to one feeding lock hopper, the top of any feeding lock hopper is communicated with the bottom of the discharging bin located above, the bottom of any feeding lock hopper is communicated with the top of the dip pipe corresponding to the feeding lock hopper, a feeding valve is arranged at the top of any feeding lock hopper, and a discharging valve is arranged at the bottom of any feeding lock hopper. According to the invention, solid materials such as blocky or irregular-shaped energetic garbage solid wastes can be directly put into the gasification furnace for gasification treatment so that the universality and the generality of the organic solid waste molten iron bath gasification device are greatly improved, and meanwhile, the material pretreatment workload and the processing cost before the materials are put into the furnace can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment. More specifically, the invention relates to a dip tube feeding type organic solid waste molten iron bath gasification device. Background technique [0002] In terms of solid waste and biomass waste treatment, compared with the traditional process, molten iron bath is a more advanced process for converting hazardous waste into low-carbon energy. The molten iron bath sprays organic solid waste particles into the molten bath at high speed, and blows a gasification agent such as pure oxygen for thorough treatment and conversion, converting hydrocarbon elements into clean synthesis gas (carbon monoxide and hydrogen), both It can be used as fuel gas, and can also be used in chemical synthesis, such as methanation to produce natural gas, Fischer-Tropsch synthesis to produce gasoline and diesel, etc., while most of the inorganic matter remains in the slag floating on the surface, achieving...
