| titleOfInvention | Method and device for preparing furfural from agricultural and forestry waste biomass with low water consumption and low energy consumption |
| abstract | The invention relates to a method and a device for preparing furfural from agricultural and forestry waste biomass with low water consumption and low energy consumption. The method comprises: crushing the biomass into fragments, mixing with acid and then loading it into a stripping kettle; The steam is used to strip the biomass; the stripping gas produced by the stripping is output from the stripping kettle, and after being heated and pressurized, it enters the stripping kettle again to strip the biomass to form a cycle. The device includes a stripping kettle, a pressurizing device and a gas-liquid separator that are connected in sequence to form a loop, and the pressurizing device is used to pressurize and warm the stripping gas output from the stripping gas outlet, and pressurize the temperature-increasing and pressurizing gas. The stripping gas is sent to the stripping tank again to form a cycle. The method realizes that the hemicellulose components in the biomass raw material are gradually converted into furfural by continuously stripping the circulating steam, and the concentration of furfural in the steam at the outlet of the stripping kettle is gradually increased. At the same time, the steam consumption and waste water discharge of furfural production are also significantly reduced. |
