Description

During specific use, the steaming material will enter the separator 3 through the ball valve 1 and the injection pipeline 2 in sequence, and the separation process will be completed in the separator 3 . Since the steamed material after the separation operation will contain a large amount of substances that have an inhibitory effect on the subsequent enzymolysis and fermentation process, it is necessary to transport the separated steamed material to the washing device 5 through the conveying device 4, and the steamed material will be treated by the washing device 5. The water washing operation is carried out to remove the inhibitors in the steaming material (that is, the substances that inhibit the subsequent enzymolysis and fermentation, such as formic acid, acetic acid, levulinic acid, etc.), so as to ensure the smooth progress of the subsequent enzymolysis and fermentation process.

It can be seen that there are certain defects in the existing steam-explosive material processing system: the washing device 5 consumes a lot of energy, and the water content of the steam-explosive material after washing treatment is relatively high, so it is necessary to adopt some equipment to dry the steam-explosive material The whole process not only prolongs the time required for the follow-up processing of the steamed material, but also increases the space occupied by the entire steamed material processing system by the water washing device 5 and the conveying device.

Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

Referring to Fig. 2, Fig. 2 is a preferred structure of the steam explosion material processing system provided by the embodiment of the present invention. As shown in Figure 2, this embodiment includes a water washing system and a separation system, wherein the water washing system is used to wash the steam explosion material produced after the steam explosion process, and the washed steam explosion material contains a large amount of water. The separation system is connected with the water washing system, which is used to separate solid, liquid and gas from the steamed material after washing, so as to obtain solid steamed material, water washing liquid and non-condensable gas. These solid steamed materials will be sent to the follow-up device Enzymolysis and fermentation are carried out in the environment, and the washing liquid and non-condensable gas are treated with relevant three wastes.

In this embodiment, the steaming material is first washed with water, so that the steaming material is mixed with a large amount of water, so that the substances contained in the steaming material that greatly inhibit the subsequent enzymatic hydrolysis and fermentation process can be dissolved into the water. When the steaming material rich in a large amount of water passes through the separation system, the water rich in the steaming material and the inhibitors dissolved in the water will be separated, and then the solid steaming material, washing liquid and non-condensable gas will be obtained. In the prior art, the processing of the steamed material by the steamed material treatment system requires three steps of separation, washing and drying in sequence, while the steamed material treatment system provided by the embodiment of the present invention only needs to perform two steps of washing and separation in sequence. It can be seen that the steam-explosive material processing system provided in this embodiment can shorten the time required for the existing steam-explosive material processing system to process the steam-explosive material. The space occupied by the system.

Continuing to refer to FIG. 2 , in this embodiment, the nozzle 6 is used to decompress and accelerate the steaming material, and the connecting pipe 7 is used to form a negative pressure zone in the connecting pipe 7 after the high-speed steaming material flows through.

During specific implementation, after the steaming material with a faster speed and a certain pressure flows through the nozzle 6, the steaming material moves at a high speed and passes through the inner cavity of the connecting pipe 7, and the steaming material moving at a high speed will take away the air in the connecting pipe 7 together , the air pressure in the connecting pipe 7 will drop rapidly like this, a negative pressure zone will be formed in the connecting pipe 7, and the water connected to the first end of the bypass pipe 9 will be sucked in the connecting pipe 7 under the effect of the pressure difference. Since the high-speed steaming material continues to flow through the connecting pipe 7, water will be continuously sucked into the connecting pipe 7. Then the steaming material and water are mixed together in the mixing pipe 8 and injected into the separation system through the spray nozzle 10 . It can be seen that the above water washing process is a self-washing process, the energy consumed in the water washing process comes from the steam explosion itself, and no other energy is consumed, so this process improves the utilization rate of the energy generated by the steam explosion material in the steam explosion process.

When the steaming material passes through the mixing tube 8, flows out through the first through hole on the nozzle 10, and is sprayed onto the blade 11, because the steaming material rich in water still has relatively large energy, the steaming material exerts an impact force on the blade 11, and the blade 11 Under the action of the impact force, the inner cylinder 12 acquires kinetic energy and starts to rotate around the axis LL. The blade 11 rotates with the inner cylinder 12 and drives the water-rich steaming material to rotate together. Since the density of water is greater than that of the dry steaming material, the centrifugal force of the rotating water is greater than that of the dry steaming material, so the absolute steaming material in the steaming material Most of the moisture will be thrown out from the first through hole, and flow down along the inner wall of the outer cylindrical body 13 (direction shown by arrow A in Figure 2); Flow down the inner wall of the inner cylinder 12 (direction shown by arrow B in Figure 2) and be collected for the next step; gaseous state is discharged from the top of the outer cylinder (direction shown by arrow C in Figure 2 ). In this way, the steaming material can better realize the separation of solid, liquid and gas.

In this embodiment, the steaming material is evenly sprayed from the spray head 10 in all directions along the second through hole, so that the vanes 11 are evenly stressed, and the inner cylinder 12 is guaranteed to rotate stably.

To sum up, the steam explosion material processing system provided by the embodiment of the present invention can shorten the time required for the steam explosion material processing system in the existing steam explosion material processing system, reduce the space occupied by the steam explosion material processing system, and improve the steam explosion efficiency of the steam explosion material.
