Embodiment

[0041] A company produces and discharges 2.6 million tons of vinegar grains every year. The vinegar grains contain 6% to 10% of crude protein, 2% to 5% of crude fat, 20% to 30% of nitrogen-free extracts, 13% to 17% of ash, and 0.25% of calcium. %~0.45%, phosphorus 0.16%~0.37%. Taking the vinegar grains discharged by the company as the test object, gas is produced on a small-scale test device, and medium calorific value gas is produced and separated to replace or mix with commercial gas for direct combustion to obtain high-temperature steam necessary for the vinegar brewing process.

[0042]First, the high-humidity vinegar grains with a moisture content of 70% are pretreated with quicklime to obtain wet vinegar grains with a moisture content of 30-35%, and then the wet vinegar grains are sent to the vinegar grain drying device 7 at a speed of 220 kg per hour. After treatment, dry vinegar grains with a moisture content of 26% to 30% are obtained; then the dried vinegar grains ar...

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...
