High-humidity vinegar residue gasification direct combustion utilization device and method thereof

Abstract

The invention provides a high-humidity vinegar residue gasification direct combustion utilization device and a method thereof. The high-humidity vinegar residue gasification direct combustion utilization device is characterized in that the traditional heating manner is abandoned, and the electric induction heating method is adopted to provide stable and continuous heat for a reactor and realize producing of medium heat value fuel gas through pyrolysis and gasification of wet vinegar residue. In addition, a gasified product decoking-free direct combustion utilization technology is disclosed, that is, the high-temperature state gasified product is separated to obtain the medium heat value fuel gas, and the medium heat value fuel gas can be directly combusted, so that a condensible hydrocarbon gaseous product is prevented from condensation to form tar, and efficient utilization of the gasified product is utilized; and moreover, the waste heat of the tail gas obtained through combustion of the fuel gas is directly utilized to dry the wet vinegar residue, so that the water content of the wet vinegar residue reaches the best range required by the gasification range.

Description

technical field [0001] The invention relates to the technical field of renewable energy, in particular to a high-humidity vinegar residue gasification direct combustion utilization device and a method thereof. Background technique [0002] Vinegar grains are solid waste produced in the process of making vinegar. They are grain raw materials, such as rice, wheat, sorghum, etc., and the residue left after brewing vinegar. Its main component is rice husk. Vinegar grains have the characteristics of high moisture content, high salinity, strong acidity, slow natural decomposition, and large space resources. Long-term stacking of vinegar grains not only takes up a lot of space, but also pollutes the surrounding air, water and soil environment. [0003] Biomass gasification is the process of converting solid biomass into gaseous fuels through thermochemical reactions at high temperatures. The process uses air and water vapor as the gasification agent, and O in the air 2 A combusti...

AI Technical Summary

Problems solved by technology

Although this technical scheme reuses the waste vinegar grains, it cannot make full use of the energy contained in the vinegar grains due to insufficient combustion.

In addition, due to the direct combustion of vinegar residues, the condensable hydrocarbon gaseous products in the product gas will form tar after condensation, which will reduce the heat transfer efficiency of gas-fired boilers and pose potential safety hazards
