Biomass fuel generator

This invention relates to a biomass fuel generator, and more particularly to a self-heating continuous biomass fuel generator for substantially increasing the effectiveness of preparing biomass fuel.

In recent years, the global price of high-grade fossil fuels and the issue of greenhouse gas reduction have made the utilization of biomass energy more and more important, and also brought huge business opportunities for biofuels. However, compared to conventional fossil fuels, the energy density of the biomass fuel is lower, which increases the cost of transportation, storage and use of the biomass fuel. According to statistics, it is estimated that by 2025, the development potential of biomass energy worldwide will reach 200 million 瓩, accounting for more than 6% of the world's power generation capacity. In terms of the market potential of Taiwan's biomass energy, according to the statistics of the Environmental Protection Agency, Taiwan currently produces about 10 million metric tons of biomass energy such as garbage, waste wood and agricultural waste. According to the statistics of agricultural and animal husbandry wastes in Taiwan, the equivalent coal consumption of various types of biomass waste is 1.56 million tons/year, and the equivalent coal consumption of municipal waste is 2.3 million tons, which is higher than the fuel price. Unsurprising international trends, biofuels are renewable energy sources with great potential for application. However, most of the raw material energy production and use areas are not the same, and the production of raw energy energy is regional and seasonal, so how to effectively store and transport biomass energy is the most important issue in the use of biomass energy.

Figure 1 is a schematic representation of the conversion of conventional biomass to biomass fuel, wherein the biomass is exemplified by wood. Referring to Figure 1, in general, biomass (wood, straw, etc.) can be converted into biomass fuel by anoxic heating, and the energy density of the biomass fuel is usually positively related to the time and temperature of heating. . After heating, the wood emits syngas, carbon monoxide (CO), carbon dioxide (CO ₂ ), etc., as well as acid (Acetic Acid), methanol (Methanol), other organic substances (Organic), tar ( Bad substances such as Tar), Resin, etc., which in turn increase the energy density to be converted into a biomass fuel.

In order to carry out the above-mentioned, after the preliminary discharge of the synthesis gas and the undesirable substances in the wood, the biomass of the wood is converted into a lignite such as lignite by a charcoal baking method of heating at 200 ° C to 300 ° C for 2 to 3 hours. Biomass fuel. Next, the Charcoal method of heating at an inert gas of 600 ° C or more for 5 hours or more can further increase the energy density of the biomass fuel to the level of charcoal.

Biomass carbon baking technology is one of the feasible technologies for the upgrading of solid biomass fuel. Since the biomass is rich in water and is not conducive to storage and transportation, and if the biomass is directly burned, it will generate smoke and other harmful substances. Therefore, the carbon baking technology places the biomass in an oxygen-deficient and high-temperature environment, and the biomass is placed inside the biomass. The water and volatile matter contained are removed to increase the shelf life of the biomass and reduce transportation costs. However, the existing biomass charcoal baking technology (or carbonization technology), which is mostly heated by external heating, will offset the cost of transportation cost reduction by increasing energy consumption, and thus cannot effectively reduce the overall carbon baking cost (or Carbonization technology).

The thermal energy supply of the biomass charcoal baking technology can be mainly divided into two types: combustion mode heating or electric heating mode. Both of these heating methods require considerable energy, which is not helpful for the production cost of the raw fuel. Therefore, it is necessary to develop a self-heating type of carbon baking (or carbonization) process and equipment. In addition, most of the current carbon baking technologies are batch-type production techniques, and it is often impossible to produce biomass fuels in large quantities quickly. Therefore, it is also necessary to develop continuous carbon baking (or carbonization) processes and equipment.

In view of the above, the present invention provides a self-heating continuous type biomass fuel generator to greatly reduce the production cost of biofuel, and to rapidly produce biomass fuel in large quantities.

Simply put, the moving particle bed has the characteristics of high temperature, long-term operation and heat storage, and is quite suitable for the application of biomass carbon baking technology. Through proper design, the technical means of synthesizing gas to recover direct heating of the bed, indirectly heating the biomass and bed mixture, temperature control device and bed cycle control can be stably stabilized at the appropriate reaction temperature and appropriate residence time. To achieve the purpose of charcoal baking (or carbonization) of the biomass by self-heating, overcome the key obstacle of the energy consumption of the biomass baking charcoal, and effectively remove the water from the biomass to obtain the carbon-baked product with higher secondary value ( Or carbonized finished products), reduce the cost of raw fuel production and increase product applicability.

The present invention provides a biofuel generator suitable for converting biomass into a biomass fuel. The biofuel generator includes a first moving particle bed, a second moving particle bed, a bed material, and a separating device, wherein the first moving particle bed includes a first bed body and a first bed quality inlet connecting the first bed body, first a bed outlet, a raw material inlet and a syngas outlet, and the second moving particle bed includes a second bed and a second bed inlet, a second bed outlet, a syngas inlet and an air inlet connecting the second bed, and The first bed inlet is connected to the second bed outlet and the syngas inlet is connected to the syngas outlet. The bed quality moves from the second bed inlet into the second bed, and moves to the first bed through the second bed outlet and the first bed inlet to heat the autogenous inlet into the first bed. The biomass transforms the biomass into a biomass fuel and emits syngas. After the syngas enters the second bed through the syngas outlet and the syngas inlet, it is mixed with the air entering the second bed from the air inlet to heat the bed in the second bed. The separating device is connected to the first bed outlet to separate the raw fuel from the bed, wherein the raw fuel and the bed enter the separating device via the first bed outlet.

In summary, in the biofuel generator of the present invention, the biomass is heated by the bed material to discharge the biomass into the syngas, and the syngas is burned to reheat the bed, so that the cycle does not need to be The outside world provides a heat source to heat the biomass to effectively reduce the cost of making the raw fuel.

The above-described features and characteristics of the present invention will become more apparent from the following detailed description.

2 is a schematic diagram of a biofuel generator in accordance with an embodiment of the present invention. Referring to FIG. 2, the biomass fuel generator 200 of the present invention includes a first moving particle bed 210, a second moving particle bed 220, a bed quality 230, and a separating device 240, wherein the first moving particle bed 210 is connected to the second moving Between the particle bed 220 and the separation device 240, the bed 230 can be moved from the second moving particle bed 220 to the first moving particle bed 210 and then to the separation device 240. In the present embodiment, the bed material 230 is, for example, quartz sand, ceramic particles or other suitable high specific heat material, and is automatically moved downward by gravity like an hourglass.

Specifically, the first moving particle bed 210 includes a first bed 211, a first bed inlet 212, a first bed outlet 213, a biomass inlet 214, and a syngas outlet 215, and the first bed inlet 212, A bed outlet 213, a raw material inlet 214 and a syngas outlet 215 are connected to the first bed 211 as an inlet and outlet of the first moving particle bed 210. Similarly, the second moving particle bed 220 includes a second bed 221, a second bed inlet 222, a second bed outlet 223, a syngas inlet 224 and an air inlet 225, wherein the second bed inlet 222, the second bed The mass outlet 223, the syngas inlet 224 and the air inlet 225 are connected to the second bed 221 as an inlet and outlet for the second moving particle bed 220.

In response to the above, the first bed inlet 212 is connected to the second bed outlet 223, and the syngas inlet 224 and the syngas outlet 215 are interconnected to form a space between the first moving particle bed 210 and the second moving particle bed 220. Connection relationship. The separating device 240 is connected to the first bed mass outlet 213 to constitute a connection relationship between the first moving particle bed 210 and the separating device 240.

In addition, the bed material 230 enters the second bed 221 via the second bed inlet 222, and the biomass 50 enters the first bed 211 via the biomass inlet 214. In the present embodiment, the biomass 50 is, for example, a biomass energy source such as wood or agricultural waste, and is cut into a small block in advance to facilitate mixing and heating with the bed 230.

The bed 230 will slowly flow downward in the second bed 221 and flow to the first bed 211 via the second bed outlet 223 and the first bed inlet 212 to mix with the biomass 50 and to the biomass. 50 is heated (the process of heating the bed 230 will be detailed later). Next, the bed 230 and the biomass 50 flow slowly downward, and the bed 230 continues to heat the biomass 50 during the moving process to convert the biomass 50 into the biomass fuel 60, wherein the biomass fuel 60 is removed. The syngas increases the energy density, and the volume of the biomass fuel 60 is smaller than the original biomass 50.

Further, the bed quality 230 and the biofuel 60 enter the separation device 240 via the first bed mass outlet 213. In the present embodiment, the separation device 240 is, for example, a cyclone to be adapted to separate the biomass fuel 60 from the bed 230. Then, the separated raw fuel 60 can be stored or transported, and the recovered bed 230 can be re-entered into the second bed 221 via the second bed inlet 222 for a circulation heating process.

Since the process of preparing the biomass fuel 60 of the present invention continuously feeds the biomass 50 from the biomass inlet 214, the biomass 50 is converted into the biomass fuel 60 by the process of oxygen-deficient heating, so that compared with the conventional one, In terms of batch technology, the continuous preparation technique of the present invention provides uninterrupted access to the biomass 50 to produce the biomass fuel 60, thereby greatly increasing throughput and equipment utilization.

In addition, the separating device 240 can further connect the second bed inlet 222 to directly feed the bed 230 separated from the raw fuel 60 into the second bed 221 . Of course, in other embodiments, the recycled bed quality 230 may be recirculated through other transportation equipment, but the invention is not limited thereto.

Referring again to Figure 2, the process of heating the bed 230 will be detailed below. In this embodiment, after the biomass 50 is heated by the bed 230, syngas (not shown) is released to increase the energy density, wherein the syngas is a combination of carbon monoxide CO and hydrogen H ₂ and the like. gas. These syngas will slowly move upwardly in the voids of the bed 230 and the biomass 50 and enter the second bed 221 via the syngas outlet 215 and the syngas inlet 224.

In addition, the present invention also introduces air (not shown) from the air inlet 225 adjacent to the syngas inlet 224 into the second bed 221 to mix the air with the syngas for combustion to heat the bottom of the second bed 221 The bed quality is 230. Then, the heated bed 230 slides along the second bed outlet 223 and the first bed inlet 212 to the top of the first bed 211 to heat the biomass 50, and the biomass 50 releases the syngas. . According to the above-mentioned cyclic process, the self-heating type biofuel generator 200 of the present invention can be burned and heated by the syngas discharged from the biomass 50 without the external energy supply to prepare the biomass fuel 60, so the present invention can be Effectively reduce the cost of making biofuel 60.

Generally speaking, the syngas released by the biomass 50 is not easy to burn, especially when the proportion of hydrogen H ₂ in the syngas is low (depending on the type of the biomass 50), so the present embodiment is a syngas and air. Super-combustion is carried out to make the synthesis gas easier to burn with air. When both the syngas and the air are at room temperature, the mixing ratio of the synthesis gas phase to the air needs to be greater than a specific value, and the synthesis gas starts to burn with the air. However, when both the syngas and the air are above room temperature, the aforementioned specific value is lowered so that the syngas and air of a lower mixing ratio can be burned, which is called super-combustion.

In addition, the temperature of the syngas and air is usually inversely related to the specific value described above, that is, when the temperature of the syngas and air is higher, only a small amount of syngas can be burned to heat the second bed. Bed quality 230 in the bottom of body 221 . Therefore, similar to the initiating operation of the incinerator, the embodiment can also perform the pre-burning process first.

In the above embodiment, the biofuel generator 200 may further include a pilot burner (not shown) to preheat the bed 230 located in the second bed 221 . These heated bed qualities 230 will flow down to the first bed 211 to heat the biomass 50 to vent the syngas. During the upward movement of the syngas to the bottom of the second bed 221, it is also continuously heated by the downward moving bed 230. Similarly, the air entering the bottom of the second bed 221 from the air inlet 225 is also The bed quality 230 is heated. When the temperature of the syngas and air exceeds their respective super-combustion temperatures, the syngas and air spontaneously begin to burn. Next, there is no need to use a pilot to heat the bed 230 in the second bed 221. This is because the synthesis gas is mixed with air to burn enough to heat the bed 230 to the desired operating temperature, and only needs to be continuously accessed. The biomass 50 is prepared by preparing the biomass fuel 60 in a self-heating manner.

In detail, when the syngas directly heats the moving bed 230 in the second bed 221 by super-combustion, the hot gas can provide stable high-temperature charcoal roasting by buoyancy effect and bed 230 revolving characteristics. Carbonized environment. That is, the hot gas generated by the combustion of the bottom of the second bed 221 slowly heats the bed 230 in the middle and the top of the second bed 221 by the buoyancy effect, while the bed 230 in the middle and the top of the second bed 221 is downward. When flowing, its temperature also rises slowly. When the bed 230 moves to the vicinity of the syngas inlet 224 and the air inlet 225, the bed 230 temperature has reached a certain level, and the high temperature syngas and air enter the porous bed 230 having a porous characteristic, and the super-combustion is performed.

In order to uniformly heat the synthesis gas to heat the bed 230 in the bottom of the second bed 221, the syngas outlet 215 and the syngas inlet 224 are, for example, annular structures to produce an annular flame to uniformly heat the bed 230, but the present invention The structure of the syngas outlet 215 and the syngas inlet 224 is not limited. In addition, in order to avoid heat loss of the first bed body 211 and the second bed body 221, the embodiment can also cover the first bed body 211 and the second bed body 221 with a heat insulating material (not shown) to effectively utilize the self. Heat source.

In the present embodiment, the raw fuel 60 is prepared mainly in a carbon baking manner for better energy use. Therefore, the temperature of the first bed body 211 can be set between 200 ° C and 500 ° C, and the air pressure of the first bed body 211 is, for example, less than 2 atmospheres to provide a stable and uniform carbon baking environment of the biomass 50 . Similarly, the temperature of the second bed 221 can be set between 500 ° C and 1000 ° C, and the air pressure of the second bed 221 is, for example, less than 2 atmospheres to provide a stable and uniform super-combustion environment for the syngas.

In view of the above, the temperature of the synthesis gas combustion is usually greater than 1000 ° C to heat the bed in the bottom of the second bed 221 to 230 to 500 ° C or more. As the bed 230 flows downward, heat is lost. When the bed 230 is transferred to the first bed 211, the biomass 50 is uniformly heated at a temperature between 200 ° C and 500 ° C to prepare a biomass fuel 60. It should be noted that the foregoing temperature setting is only an example of the carbon baking condition of the present invention, but the preparation procedure of the biofuel generator 200 of the present invention is not limited to the carbon baking technique, and those skilled in the art can refer to the foregoing description. The preparation conditions of the biomass fuel 60 (e.g., the conditions for carbonization preparation) are easily adjusted, but it is still within the scope of the present invention.

Referring to FIG. 2 again, in order to effectively control the temperature of the bed 230 to form a stable heating environment, the present embodiment may further add a plurality of valves to control the flow rates of the bed 230, the syngas, and the biomass 50, respectively. Specifically, the biofuel generator 200 may further include a first valve 252, a second valve 254, a third valve 256 and a fourth valve 258, wherein the first valve 252, the second valve 254, the third valve 256 and the The four valves 258 are each, for example, a ball valve controller.

The first valve 252 is coupled between the first bed inlet 212 and the second bed outlet 223 to control the flow of the bed 230 located in the bottom of the second bed 221 into the first bed 211. The second valve 254 is connected to the biomass inlet 214 to control the flow of the biomass 50 into the first bed 211. The third valve 256 is coupled between the first bed mass outlet 213 and the separation device 240 to control the flow of the bed material 230 and the biomass fuel 60 into the separation device 240. The flow control of the first valve 252, the second valve 254, and the third valve 256 are matched to each other to achieve an appropriate heating rate. The fourth valve 258 is connected between the syngas inlet 224 and the syngas outlet 215 to control the flow rate of the syngas into the second bed 221, thereby adjusting the mixing ratio of the syngas to the air for proper super-combustion. . Those who are familiar with the art can easily understand that there is no longer much ink.

Incidentally, in addition to the flow rate of the first valve 252 for controlling the bed 230 to enter the first bed 211, the air can be prevented from entering the first bed 211 from the second bed 221 so that the biomass 50 can be Anoxic heating is performed in the first bed 211. Similarly, the second valve 254, the third valve 256, and the fourth valve 258 can also prevent air from entering the first bed 211.

3 is a schematic view of a biomass fuel generator according to another embodiment of the present invention, and for the sake of simplicity, members of the same function name will still be given the same reference numerals, and the bed quality is omitted due to the reduced illustration. Qualitative and biomass fuels, which are familiar to the artist, can be easily understood in conjunction with Figure 2. Referring to FIG. 3, the biofuel generator 300 of the present embodiment is similar to the aforementioned biofuel generator 200 (shown in FIG. 2) except that the separation device 340 of the biofuel generator 300 includes a separation tank. 341, a first conduit 342, a second conduit 343, and a pressurizer 344.

In the above, the first conduit 342 is connected to the separation groove 341 and the first bed outlet 213, and the second conduit 343 is connected to the separation groove 341 and the second bed inlet 222, and the first moving particle bed 210 and the second moving particle The bed 220 and the separation device 340 form a closed loop so that bed quality (not shown) can circulate therein. In addition, the pressurizer 344 is adapted to blow the biomass fuel (not shown) and the bed material along the first conduit 342 into the separation tank 341 in a pressurized gas manner, and automatically separate the gravity in the separation tank 341. Biomass fuel and bed quality, wherein the lighter biomass fuel leaves the separation tank 341 along the top outlet of the separation tank 341, and the heavier bed will re-enter the second bed 220 along the second conduit 343 to continue heating. .

Incidentally, although the energy density of the raw fuel is higher than that of the raw material, the density of the raw fuel is still much smaller than that of the bed, so that both can be separated by gravity, but the present invention does not limit the separation of the raw fuel and the bed. The type of quality. In addition, in order to enhance the effect of separating the raw fuel and the bed quality, the separating device 340 may further include a screen 345, wherein the screen 345 is disposed in the separating tank 341 to allow the raw fuel to pass through and block the passage of the bed. In addition, although the illustration of the present embodiment only shows a single separation groove 341, in other embodiments, a plurality of separation grooves 341 connected in series may be utilized to enhance the separation effect, which can be easily understood by those skilled in the art. No more explanations will be made.

In the present embodiment, the pressurizer 344 is pressurized with normal temperature air, so that the bed material is more likely to lose heat during the recovery process, and an embodiment will be further described below to illustrate how the present invention makes good use of all endogenous self-heating. energy.

4 is a schematic diagram of a biomass fuel generator in accordance with yet another embodiment of the present invention. Referring to FIG. 4, the biofuel generator 400 of the present embodiment is similar to the aforementioned biofuel generator 300 (shown in FIG. 3) except that the second moving particle bed 220 of the biofuel generator 400 is different. The exhaust gas outlet 426 is further included, and the separation device 340 further includes a third conduit 446. Further, the exhaust gas outlet 426 is connected to the second bed 221 and is located at the top of the second bed 221, and the third conduit 445 is connected to the exhaust gas outlet 426 and the pressurizer 344.

The synthesis gas and the air are mixed and burned in the second bed 221 to generate combustion exhaust gas (not shown), and the combustion exhaust gas moves upward to exit the second bed 221 from the exhaust gas outlet 426 to enter the third conduit 445. Next, the combustion exhaust gas is pressurized by the pressurizer 344 to blow the raw fuel and the bed material into the separation tank 341. Since the combustion exhaust gas is still a high-temperature gas, the high-pressure combustion exhaust gas can maintain the bed temperature moderately during the process of recovering the transport bed quality, thereby making full use of all the self-generated heat sources in the system. Similar to the foregoing, the first conduit 342, the second conduit 343, and the third conduit 445 are further provided with a heat insulating material (not shown) to effectively utilize the self-heating heat source.

In summary, in the biofuel generator of the present invention, the biomass is heated by the bed material to discharge the biomass into the syngas, and the syngas is burned to reheat the bed, so that the self-heating cycle is performed. There is no need to provide a heat source to heat the biomass, so as to effectively reduce the cost of making the raw fuel. In addition, the biomass fuel generator of the present invention is a continuous process to produce a mass of fuel in a rapid amount.
