Embodiment 1

[0024] see Figure 1-2 , an energy-saving and high-efficiency biomass fiber separation device, comprising a base 1, a support frame 2 and a separation box 3, the top and bottom of the separation box 3 are respectively provided with a feed port 5 and a discharge port 4, and the inside of the separation box 3 is from the top A biomass raw material pulverizing device, a screening device and a centrifuging device are sequentially arranged downwards, and the pulverizing device, the screening device and the centrifuging device are jointly connected with a driving device. When working, the biomass raw material enters the separation box 3 from the feed port 5, the driving device drives the crushing device to crush the biomass raw material, the screening device screens the crushed raw material, and the centrifugal device separates the biomass fiber to remove hemicellulose .

[0025] The specific type of the crushing device is not limited. In this embodiment, preferably, the crushing d...

Embodiment 2

[0034] see image 3, in order to improve the stability of the sieve plate 20 when lifting, this embodiment is further improved on the basis of Embodiment 1. The improvement is that: a vertical guide rod 24 is fixedly installed on the baffle plate 15, and the guide rod 24 The activity runs through the sieve plate 20, and the rollover of the sieve plate 20 is prevented by setting the guide rod 24, and the stability is improved.

[0035] In summary, the biomass raw material enters the separation box 3 from the feed port 5, the driving device drives the crushing device to crush the biomass raw material, the screening device screens the crushed raw material, and the centrifugal device separates the biomass fiber to remove hemicellulose , the structure is simple, by improving the crushing effect of biomass raw materials, and further improving the separation effect of hemicellulose, the practicability is improved.

Abstract

The invention discloses an energy-saving and efficient biomass fiber separation device. The energy-saving and efficient biomass fiber separation device comprises a base, a supporting frame and a separation box, wherein a feeding opening and a discharging opening are formed in the top and the bottom of the separation box respectively; the separation box is internally provided with a biomass raw material crushing device, a screening device and a centrifuging device in sequence from top to bottom; and the crushing device, the screening device and the centrifuging device are commonly connected with a driving device. Biomass raw materials enter the separation box from the feeding opening; the driving device drives the crushing device to crush the biomass raw materials, the screening device to screen the crushed raw materials and the centrifuging device to separate biomass fibers, so that hemicellulose is removed; the energy-saving and efficient biomass fiber separation device is simple in structure; and the crushing effect of the biomass raw materials is improved so that the separation effect of the hemicellulose is improved and the practicability is improved.

Description

technical field [0001] The invention relates to the field of biomass fiber treatment, in particular to an energy-saving and high-efficiency biomass fiber separation device. Background technique [0002] The composition of cellulosic biomass is complex, mainly composed of "three major elements": cellulose, hemicellulose and lignin, in which the content of cellulose is 30-40%, the content of hemicellulose is 15-30%, and the content of lignin is 20%. -30%, the contents and types of the three components of different fibrous biomass raw materials are quite different, and the specificity of industrial catalysts or biological enzymes makes it easy to obtain phenolic substances in the process of depolymerization of fibrous biomass Or deactivation in the presence of humin, etc., making it difficult to directly hydrolyze cellulosic biomass into ethanol in one step. Generally, through the efficient pretreatment method, the hemicellulose in the fibrous biomass raw material is selective...
