Embodiment Construction

[0016] Such as figure 1 , 2 The biomass cellulose ethanol horizontal tube continuous cooking steam explosion equipment shown in . The cooking pipe 5 is connected, and the horizontal cooking pipe is composed of a steaming pipe, a central shaft and a spiral blade, and the steaming pipe is connected with a steam input pipeline 11, and the spiral blade is composed of a plurality of spiral blades with different pitches and different diameters, so that the pitch is between Unequal distances are formed within a certain range to ensure that the material filling between the pitches reaches the maximum value. On the edge of the smaller-diameter helical blade, there are setting teeth, and the two adjacent teeth are inclined to the two sides respectively, so as to ensure that the solid material is fluffy, separated and not agglomerated during the turning process. The outlet of the horizontal cooking pipe is connected with a horizontal feeder 6 , the helical blades of the feeding screw ...

Abstract

The invention discloses a transverse tube continuous cooking and steam explosion apparatus for biomass cellulosic ethanol, which is provided with a preevaporation spiral tube and a transverse cooking tube, wherein the preevaporation spiral tube is connected with the transverse cooking tube through a spiral cork press and a T-shaped tube; the transverse cooking tube comprises an evaporation tube, a central shaft and a spiral blade; the evaporation tube is communicated with a steam input pipeline; the spiral blade comprises multiple spiral blade sections which have unequal thread pitches and unequal diameters; the edges of the spiral blade sections having small diameters are provided with shift teeth; every two neighboring ones among the shift teeth are respectively inclined towards the two sides; an outlet of the transverse cooking tube is connected with a horizontal blanking unit; a spiral blade of a feeding screw of the horizontal blanking unit is transversely arranged; and the horizontal blanking unit is connected with a pressurizing jet and explosion unit. The invention can realize large-scale production, ensures that raw materials are uniformed in cooked rate and straw fibers are pulverized and physically shaped into fine and soft pieces through steam explosion, and completely increases the late enzymolysis saccharification yield; and steam and a water source can be recycled, thereby saving the energy and reducing the consumption.

Description

technical field [0001] The invention belongs to the technical field of biomass cellulose fuel ethanol preparation, in particular to a biomass cellulose ethanol horizontal tube continuous cooking steam explosion equipment. Background technique [0002] At present, the experimental production process of grass cellulose ethanol fuel basically adopts the original, manual operation intermittent high-temperature steam explosion method, which is backward in technology, low in efficiency, dirty in the environment, and has potential safety hazards; straw fibers are statically filled with steam in the tank , due to the uneven dryness and wetness of the raw materials, the uneven density of the briquette, the uneven filling amount of each tank, the uneven temperature and pressure of the steam added to each tank, and other artificially controlled reasons, resulting in inconsistent raw and cooked raw materials after steam explosion and crushing, which often occurs There are steamed coke m...
