Example (b):

referring to fig. 1 to 3, the storage structure for biomass particles in the preferred embodiment of the present invention includes a cylindrical main bin 1, wherein an axis of the main bin 1 is preferably vertically disposed, and is further preferably a square bin structure, and is supported on the ground by a bin seat 10. The bottom of the main bin 1 is open and is provided with a discharge bin 2 at the bottom so that biomass particles can be discharged through the discharge bin 2.

Specifically, a feeding mechanism 3 is provided corresponding to the main bin 1, and preferably communicates with the top of the main bin 1 for feeding the main bin 1. In the preferred embodiment, the feeding mechanism 3 is further preferably a screw conveying mechanism, and the feeding mechanism 3 may be provided in plurality according to actual requirements.

Meanwhile, the discharge bin 2 in the preferred embodiment is preferably of a conical structure in an "inverted arrangement", such as a conical shape or a square cone shape, and is provided with an openable and closable discharge opening 6 at the bottom of the conical structure, so that the biomass particle materials in the bin can move to the discharge opening 6 spontaneously under the action of the self-weight. Correspondingly, at the discharge opening 6, a discharge mechanism 9 is provided, which, as shown in fig. 2, is further preferably a screw discharge mechanism, which allows an automatic discharge under the influence of the gravity of the biomass particles.

Further, manholes 7 are provided on the outer circumference of the main bin 1 and/or the outer circumference of the discharge bin 2 for the maintenance and repair of the storage structure. In a specific embodiment, the main bin 1 and the discharging bin 2 are provided with manholes 7 at the same time, and the manholes 7 provided on the main bin 1 are a plurality of manholes, such as two manholes shown in fig. 2, which are arranged at intervals along the axial direction (i.e. vertical direction) of the main bin 1 and are respectively used for the maintenance and repair of the upper part and the lower part of the main bin 1.

Of course, it can be understood that, according to the actual setting requirement, the manholes 7 arranged at intervals on the main bin 1 can also be arranged at intervals along the circumferential direction, so as to meet the detection requirements of different positions in the bins. Preferably, a perspective window is correspondingly arranged on the manhole 7 and used for observing the conditions in the bin through the perspective window. Correspondingly, a ladder 8 is arranged at the position corresponding to the opening of the manhole 7, as shown in fig. 1, and is used for observing the conditions in the bin through the manhole 7 when an overhaul and maintenance person goes to the corresponding platform.

Further, the heat pipes 5 are vertically arranged in the main bin 1, and the heat pipes 5 are arranged in the main bin 1 at intervals, and are further preferably arranged in an array, as shown in fig. 2. For the heat pipe 5 in the preferred embodiment, the bottom is a heat transfer end, the top is a heat dissipation end, and the heat transfer end extends to the bottom of the main bin 1, and further preferably extends into the discharging bin 2 for contacting with the biomass particles contained in the bin, so as to absorb heat generated by the biomass particles during storage; the heat dissipation end extends to the top of the main bin 1, is higher than the biomass particle storage limit height by a certain distance, and is used for contacting with a cold source to dissipate heat absorbed by the heat transfer pipe.

It should be noted that the "cold source" herein refers to a relatively cold source, i.e. an environment with a relatively lower temperature compared to the internal temperature of the biomass particles, such as an atmospheric environment in a bin, or a cooling air or cooling water environment provided for a heat dissipation end. Preferably, the top of the heat dissipation end is spaced from the top of the main bin 1 by a certain distance.

Further, a closed cavity is extended between the heat transfer end and the heat dissipation end, that is, a closed cavity is provided in the heat pipe 5, and the closed cavity is further preferably provided along the axial direction of the heat pipe 5. Meanwhile, a heat exchange substrate, such as alcohol, water or other phase change substrates, is arranged in the closed cavity of the heat pipe 5, and due to the influence of self weight, when the heat exchange substrate is in a liquid state, the heat exchange substrate is positioned at the bottom of the heat pipe 5, namely at the heat transfer end; when the heat exchange matrix absorbs heat and is converted from a liquid state to a gas state, the heat exchange matrix correspondingly moves to the heat dissipation end, releases heat at the heat dissipation end and is condensed into a liquid state, and then flows back to the hot end.

Obviously, when actually setting up, as long as the cold source temperature of relieving the cooling tube is less than the condensing temperature of heat transfer matrix can, also can promote the phase transition response speed of heat transfer matrix through changing the difference between cold source and the heat transfer matrix condensing temperature, promote the efficiency of heat transfer.

Just through the circulation switching of the heat exchange matrix in the heat pipe 5 between liquid state and gaseous state, the heat in the bin can be circularly and spontaneously transferred to the outside of the bin, and the temperature in the bin is ensured to be in a reasonable range. In addition, in order to enhance the phase change response capability of the heat exchange substrate, the air pressure in the heat pipe 5 in the preferred embodiment is negative pressure or vacuum pumping, so that the vaporization temperature of the heat exchange substrate can be correspondingly reduced, and the phase change response rate of the heat exchange substrate is enhanced.

However, according to the different types of biomass particles accommodated in the bin, the temperature rise rate and the temperature rise range of the temperature in the bin are different, and at this time, the setting parameters for the heat pipe 5 are correspondingly different, especially the setting pressure and the phase change temperature of the heat exchange matrix in the heat pipe 5 are different, which can be optimized according to the actual situation, and are not described herein.

In a specific arrangement, the heat pipe 5 is preferably a circular pipe, and the outer diameter thereof is preferably 20mm to 150mm, and more preferably 25mm to 112 mm. Meanwhile, the length of the heat transfer end is preferably 0.5m to 8m, and the length of the heat dissipation end is preferably 0.5m to 6 m. Moreover, in order to ensure the heat transfer cooling effect of the heat pipes 5, the heat pipes 5 in the preferred embodiment are a plurality of the main bins 1 arranged in parallel at intervals, so that the number of the heat pipes 5 per unit area (1 square meter) is 0.5-2, and the heat transfer effect of the heat pipes 5 is fully ensured.

Meanwhile, in order to enlarge the contact area between the heat transfer end and the biomass particles, increase the action area between the heat dissipation end and the heat dissipation medium, and improve the heat transfer performance of the heat transfer end and the heat dissipation efficiency of the heat dissipation end, the heat exchange unit is arranged on the periphery of the heat pipe 5 in the preferred embodiment, so that the contact area between the pipe body of the heat pipe 5 and a heat exchange environment is increased, and the heat transfer efficiency and the heat dissipation efficiency are improved. In a preferred embodiment, the heat exchange unit is a rib, an arc protrusion, or a groove formed on the outer circumference of the heat pipe 5. The fins can be arranged along the circumferential direction of the heat pipe 5, spirally arranged, arranged along the axial direction of the heat pipe 5, and the like. When specifically setting up, the fin of heat pipe 5 periphery sets up or is the spiral setting along the axial of heat pipe 5, and when the fin of heat pipe 5 periphery set up along the hoop, its preferred setting is the toper structure, and the major diameter end of toper structure is close to discharge bin 2, forms the horn shape structure that the opening is decurrent, so, can avoid the deposit of living beings granule on the fin, guarantees the accuracy of unloading.

Furthermore, for the heat dissipation end of the heat pipe 5, the end thereof extends out of the top surface of the biomass particles, and contacts with the cold source to realize heat exchange, thereby completing the discharge of heat transferred by the heat transfer end. In the preferred embodiment, the heat dissipation end is in contact with the atmosphere at the top inside the main bin 1 to realize heat dissipation, and the cold source is air with lower temperature than the temperature inside the biomass particles. According to the actual needs, the cold source can be set in other forms, such as cooling water and cooling air which pass over the heat dissipation end, that is, the periphery of the heat dissipation end is acted by the cooling water or the cooling air, so that the heat can be dissipated quickly, and the heat transfer and heat dissipation efficiency of the heat pipe 5 can be improved.

In the preferred embodiment, corresponding to the fixation of the heat pipe 5 in the main bin 1, at least three ways exist, namely, a support rod is arranged at the bottom of the heat pipe 5, and the bottom of the support rod is connected to the inner wall surface of the discharging bin 2; secondly, a connecting rod is arranged at the top of the heat pipe 5, the top of the connecting rod is connected to the top of the main bin 1, and the heat pipe 5 is fixed in the bin in a suspension mode; thirdly, a connecting rod or a horizontal supporting rod is horizontally arranged on the side wall surface of the main bin 1, and then the heat pipe is connected to the horizontal supporting rod or the connecting rod, so that the heat pipe 5 is fixed. In actual setting, the three modes can be preferably combined for use, so that the setting stability of the heat pipe 5 is fully ensured, and the influence on feeding and discharging of biomass particles due to the setting of the heat pipe is fully avoided.

Further, the heat dissipation that corresponds the heat dissipation end still is provided with fan 4 on the top storehouse body of main storehouse 1, and its preferred branch locates the both sides of the storehouse body, and wherein the fan 4 of one side is gone into (cold air) to the storehouse in, and the hot-air after the heat transfer is discharged to the opposite side, forms the air circulation route at the top of the storehouse body, constantly takes out the gas that the heat absorption heaies up, realizes the cooling of the endogenous material granule in the storehouse body.

The storage structure suitable for the biomass particles is simple in structure and simple and convenient to set, can realize reliable storage of the biomass particles, can quickly realize feeding and discharging of the biomass particles, can spontaneously finish quick discharge of heat generated in the storage process of the biomass particles, avoids material variation or spontaneous combustion of materials caused by heat concentration in a bin, ensures the storage stability and safety of the biomass particles, reduces the application cost of the biomass materials, and has good application prospect and popularization value.

It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
