Description

Technical Field

[0001] The present invention relates to a method for manufacturing biomass energy fuel pellets using environmental protection technology, and belongs to the field of biomass fuel manufacturing. Background Art

[0002] Biomass refers to various organisms formed through photosynthesis, including all animals, plants, and microorganisms. And so-called biomass energy is the energy form in which solar energy is stored in biomass in the form of chemical energy, that is, the energy carried by biomass. It directly or indirectly comes from the photosynthesis of green plants, can be converted into conventional solid, liquid, and gaseous fuels, is inexhaustible, and is a renewable energy source. At the same time, it is also the only renewable carbon source. The original energy of biomass energy comes from the sun. Therefore, in a broad sense, biomass energy is a manifestation of solar energy. From the perspective of the carbon cycle, the carbon source of carbon dioxide generated by the combustion of biomass energy fuel comes from the carbon dioxide absorbed from the air during the carbon fixation process of photosynthesis. Therefore, no additional carbon dioxide will be produced, which is helpful for delaying the current greenhouse effect. Therefore, biomass energy is an important research direction in the current energy field.

[0003] Existing biomass energy fuels are mostly divided into three types: solid, liquid, and gaseous. Among them, the liquid includes bioanhydrous ethanol and other organic fuels, and the most common gaseous ones are combustible gases such as biogas. Because the transportation of the above two forms of biomass fuels is relatively difficult, they are usually locally sourced and used locally. Therefore, the application of liquid and gaseous biomass energy fuels is usually restricted by the preparation materials and has obvious regional limitations, and cannot be widely promoted without discrimination. And biomass energy solid fuel is a new type of environmental protection energy in the form of blocks produced by processing straw, rice straw, rice husks, peanut shells, corn cobs, camellia oleifera shells, cottonseed shells, etc. and "three leftovers". The diameter of biomass pellets is generally 6 - 10 millimeters, which is convenient for transportation and storage.

[0004] During the preparation of biomass energy solid fuel, in order to avoid blocking the flat die granulator during the process of using the flat die granulator to prepare biomass energy solid fuel pellets, usually some moisture will remain in the raw materials. Therefore, after pelletizing and forming, the biomass energy fuel pellets are usually dried and cooled to reduce the residual moisture inside the biomass energy fuel pellets, which is convenient for subsequent transportation. However, in the above process, a large amount of energy is consumed, resulting in an increase in the manufacturing cost of biomass energy fuel pellets, which causes great trouble for the subsequent promotion and application of biomass energy fuel pellets.

[0025] Advantages of the present invention:

[0026] During the manufacturing process of the biomass energy fuel particles, the raw materials are finely pulverized by the self-grinding of the ball mill device. At the same time, absolute ethanol is added into the ball mill device as a grinding aid to reduce the loss of the materials and the ball mill device during the ball milling process. At the same time, the absolute ethanol is used to increase the humidity of the raw materials, which is convenient for subsequent granulation and forming. After the biomass energy fuel particles are formed, because the absolute ethanol has strong volatility, a countercurrent cooler can be directly selected for air drying and dehumidification, and the dehumidification task can be quickly and thoroughly completed without heating.

[0027] Through the design of the driving component, the motor drives the driving gear to rotate. While the driving gear rotates, it will drive the linkage gear and the connecting mechanism to rotate. The rotation of the linkage gear will drive the rotating part to rotate. The rotating part will drive the side bevel gear to rotate. The rotation of the side bevel gear will drive the material rack to rotate through the synchronous shaft, thereby realizing the rotation action of the biomass energy fuel particles in the material rack.

[0028] Through the design of the rotating part, when the driving component drives the rotating part to rotate, the fixed bevel gear on the rotating part will drive the side bevel gear to rotate. The rotation of the side bevel gear will drive the material rack to rotate through the synchronous shaft, thereby realizing the rotation action of the biomass energy fuel particles in the material rack.

[0029] Through the design of the adjustable holding component, when in use, the biomass fuel particles are evenly placed in several material racks, and then the cover plate is placed in the material rack and stays above the biomass fuel particles. Then, the rotating handle is used to drive the rotating shaft and the rotating seat to rotate. The traction rope will be gradually extended while the rotating seat rotates. Without the pull of the traction rope, under the action of spring one, the inclined clamping block one will extend out of the cover plate and insert into the clamping groove on the inner wall of the material rack, thereby limiting the cover plate with the adjusted position, so that a accommodating space suitable for the biomass fuel particles can be formed between the cover plate and the material rack.

[0030] Through the design of the air guide component, the fan transports the airflow into the outer cavity, and transports it to the inside of the air guide plate through the air outlet, and transports it to the upper and lower material racks through the turbulent air holes on the upper and lower sides of the air storage cavity, thereby realizing the cooling of the turbulent airflow.

[0031] Through the design of the connecting mechanism, when the motor drives the active gear to rotate, it will synchronously drive the linkage gear and the inner gear ring to rotate. When the inner gear ring rotates, it will drive the connecting shaft to rotate. The connecting shaft will drive several annular plates to rotate synchronously. The annular plates will drive several groups of air guide plates to perform horizontal rotation. In the process of the air guide plate rotating along the circumferential outer surface of the pillar, when the air storage cavity opening on the side of the air guide plate matches the air outlet of the outer cavity, the airflow in the outer cavity realizes vertical flow of air through the air storage cavity and the turbulent wind holes. When the air storage cavity opening on the side of the air guide plate is staggered with the air outlet of the outer cavity, the airflow in the outer cavity will blow horizontally through the air outlet to realize horizontal flow of air. The vertical and horizontal staggered blowing of the airflow in the outer cavity can perform airflow cooling at various angles on the biomass fuel particles in the rack.

[0032] Through the design of the connecting component, when it is necessary to perform maintenance and place biomass fuel particles in the material rack, at this time, in order to facilitate the operation of the material rack, the protruding block on the outer surface of the annular plate can be pressed upward to drive the slider and the inclined surface block 2 to move vertically, so that the inclined surface block 2 is retracted from the docking groove to the sliding groove. At this time, the connecting shaft with the top end engaged in the docking groove can be rotated and pulled out to release the current limiting state of the annular plate. Subsequently, the annular plate can be pushed to rotate to release the blocking of the current material rack by the air guide plate connected to the inner wall of the annular plate, and the corresponding operation can be performed.

Without the pull of the traction rope 17, under the action of the spring 19, the inclined clamping block 18 will extend out of the cover plate 13 and insert into the clamping groove 12 on the inner wall of the rack 11, thereby limiting the cover plate 13 with the adjusted position, so that a accommodating space suitable for the biomass fuel particles can be formed between the cover plate 13 and the rack 11; then, the fan and the motor 37 are started, and the fan conveys air. The air flow is transported to the outer cavity 4, and is transported to the inside of the air guide plate 22 through the air outlet 35, and is transported to the upper and lower sides of the material rack 11 through the turbulent air holes 24 on the upper and lower sides of the air storage cavity 23, so as to realize the cooling of the turbulent air flow; the motor 37 drives the driving gear 38 to rotate, and the driving gear 38 rotates while driving the linkage gear 36 and the inner gear ring 40 to rotate, and the linkage gear 36 rotates to drive the rotating member 5 to rotate, and the fixed bevel gear 8 on the rotating member 5 drives the side bevel gear 9 to rotate, and the side bevel gear 9 rotates to drive the material rack 11 to rotate through the synchronous shaft 10, thereby realizing the rotation of the biomass fuel particles in the material rack 11, and the inner gear ring 40 drives the connecting shaft 2 while rotating. 8 rotates, the connecting shaft 28 will drive several annular plates 26 to rotate synchronously, and the annular plates 26 will drive several groups of air guide plates 22 to perform horizontal rotation. In the process of the air guide plates 22 rotating along the circumferential outer surface of the pillar 2, when the opening of the air storage cavity 23 on the side of the air guide plate 22 matches the air outlet 35 of the outer cavity 4, the airflow in the outer cavity 4 realizes the vertical flow of air through the air storage cavity 23 and the turbulent air holes 24. When the opening of the air storage cavity 23 on the side of the air guide plate 22 is staggered with the air outlet 35 of the outer cavity 4, the airflow in the outer cavity 4 will be blown horizontally through the air outlet 35 to realize the horizontal flow of air, and the biomass fuel in the material rack 11 is blown by the vertical and horizontal staggered blowing of the airflow in the outer cavity 4. The particles are cooled by airflow at various angles; when maintenance and placement of biomass fuel particles in the material rack 11 are required, at this time, in order to facilitate the operation of the material rack 11, the protruding block 34 on the outer surface of the annular plate 26 can be pushed upward to drive the slider 31 and the inclined surface block 232 to move vertically, so that the inclined surface block 232 is received from the docking groove 29 to the sliding groove 30. At this time, the connecting shaft 28 at the top end of the docking groove 29 can be rotated and pulled out to release the current limiting state of the annular plate 26. Subsequently, the annular plate 26 can be pushed to rotate to release the air guide plate 22 connected to the inner wall of the annular plate 26 from blocking the current material rack 11, and the corresponding operation can be performed.
