Problems solved by technology

However, it is known that the hydrolytic acidification process requires a certain amount of dissolved oxygen, and requires sufficient mixing and swelling to facilitate acid production. As far as this invention is concerned, its practicability is not strong. Although the ultrasonic generator can destroy the structure of straw, it cannot When the viscosity of the material liquid is continuously increasing, the propagation loss of the ultrasonic wave will also increase, the energy consumption is high, and the effect on the overall circulation of the material liquid is not significant, which is not conducive to the uniform mixing of the material liquid

Embodiment 1

[0029] refer to Figure 1~3 , a biomass hydrolysis and acidification device of the present invention, comprising a tank body 1, a stirring mechanism, an air distribution pipe 25, a feed port 17 and a discharge port 18, the top plate of the tank body 1 is provided with a working window 23 and a ventilation window 21, and the bottom Located below the ground 20, the stirring mechanism includes: a hand-operated elevator, an agitator and a suspension rope 13, the hand-operated elevator passes through the top of the tank body 1 vertically through the working window, and is set away from the center of the tank body 1, and the agitator Slidingly connected with the hand-operated elevator, one end of the suspension rope 13 is connected with the agitator, and the other end is connected with the hand-operated elevator.

[0030]In one embodiment, the tank body 1 is cylindrical, and may also be other shapes commonly used in the art.

[0031] The ventilation window 21 is grid-shaped, and is...

Embodiment 2

[0046] refer to Figure 4 , the biomass hydrolysis and acidification device described in this embodiment is an improvement carried out on the basis of Example 1, and the difference from Example 1 is:

[0047] The air distribution pipe is evenly arranged in the bottom of the tank body 1 in a ring shape, and the distance between the air distribution pipe 25 and the bottom of the tank body 1 can be set according to the process requirements, and its height does not constitute a limitation to the present invention.

[0048] The gas entering the air distribution pipe 25 is air, and the air is pressurized by the pressurized fan and distributed to the air distribution pipe 25 by the gas main pipe 16 regularly and quantitatively according to the process requirements. Air holes 26 to ensure uniform aeration of the feed liquid.

Embodiment 3

[0050] refer to Figure 5 , the biomass hydrolysis and acidification device described in this embodiment is an improvement carried out on the basis of Example 1, and the difference from Example 1 is:

[0051] A connecting ring I10 is arranged on the connecting part I, and the connecting ring I passes through an auxiliary pull piece 12, one end of the auxiliary pull piece is connected to the agitator, and the other end is fixed on the support, the auxiliary pull piece 12 A plurality of connecting rings II11 sufficient to allow the sling to pass are arranged on the pull piece.

[0052] Among them, the connecting ring I10 is used to pass through the auxiliary pull piece 12, and the auxiliary pull piece 12 is made of high-strength engineering plastics.

[0053] The number of connecting rings II 11 can be set to be more than 2, for example, 2, 3, or even more.

[0054] In addition, in order to facilitate the removal of impurities at the bottom of the tank and facilitate maintenan...

Abstract

The invention provides a biomass hydrolysis and acidification apparatus and belongs to the technical field of straw processing. The apparatus includes a tank body, a stirring mechanism, an air distribution pipe, a material inlet, and a material outlet. A work window and a ventilating window are arranged in a top board of the tank body. The bottom of the tank body is arranged underground. The stirring mechanism includes a hand-operated lifting machine, a stirring device, and a hoisting rope. The hand-operated lifting machine is vertically penetrated through the top board of the tank body through the work window and is deviated from the center of the tank body. The stirrer is slidingly connected to the hand-operated lifting machine. One end of the hoisting rope is connected to the stirrer and the other end is connected to the hand-operated lifting machine. The apparatus enables raw materials to be contacted, impacted and mixed in the tank body completely so that impurities are removed away from the raw materials and are precipitated. A biomass material liquid, after retention for 10-15 h in the tank body, is fully moistened and expanded so as to high-effectively complete the acidification. The apparatus significantly improves the biodegradability of the material liquid and lays excellent fundament for methane production through anaerobic fermentation.

Description

technical field [0001] The invention belongs to the technical field of biomass hydrolysis acidification, and in particular relates to a biomass hydrolysis acidification device. Background technique [0002] Crop straw energy utilization technology is one of the effective ways to alleviate the three crises of "food, energy, and environment" that our country is facing today. Anaerobic fermentation technology has attracted wide attention as the main utilization technology of biomass energy. Anaerobic fermentation technology can be divided into single-phase anaerobic fermentation technology, two-phase anaerobic fermentation technology, mixed anaerobic fermentation technology. Among them, the acid-producing stage and the methanogenic stage in the two-phase anaerobic fermentation process are two independent processing units, each forming the best ecological conditions for acid-producing fermentation microorganisms and methanogenic microorganisms, so that they can exert their maxim...
