Technical field
The utility model relates to a kind of furfural gas-filtering device, also relates to a kind of hydrolysis kettle that is provided with this furfural gas-filtering device.
Background technology
Furfural (furfural) has another name called furtural, is a kind of light yellow or amber sparkling and crystal-clear transparency liquid, does not have mechanical impurity, physical property: colourless oil liquid has the special odor of similar benzaldehyde.Be exposed to that color becomes rufous very soon in light and the air, inflammable, easily and steam together volatilize.Its steam and air form explosive mixture, are slightly soluble in water, are soluble in ethanol, ether.Furfural is a kind of important organic chemical industry's product, and it has purposes widely in fields such as synthetic resin, petroleum refining, fuel, medicine and light industries.Furfural mainly is to utilize the pentosan in the plant fiber material to produce, and all plant fiber materials that is rich in pentosan all are applicable to furfural production, as corncob, cotton seed hulls, oil tea shell, sunflower pericarp, bagasse and rice husk etc.
Plant fiber material is under the effect of acidic catalyst during the preparation furfural, and through the pressurization that heats up, pentosan wherein is hydrolyzed and generates pentose earlier, and dehydration makes furfural then.At present, traditional furfural production technology is as follows substantially: acid, hydrolysis are pulverized, mixed to plant fiber material, and the furfural gas that hydrolysis produces becomes furfural stoste after condensation, furfural stoste again through distillation, neutralization, after refining the furfural finished product.Owing to contain the solid impurity of furfural dregs class in the furfural gas that hydrolysis produces, enter subsequent processing again after these solid impurities need being removed.The solid impurity of removing furfural gas at present is to connect the cyclone dust removal scummer to remove behind hydrolysis kettle, also need to increase cleaner, also cause a large amount of power consumptions, and the impurity of this method to remove rate low, at 80% time, increase subsequent processing distillation load and cleaning frequency (1 time/20 days) like this, increased the production cost of furfural greatly.
