Description

Technical Field

[0001] The invention relates to the technical field of renewable energy preparation, in particular to a buffer tank for biomass liquefaction. Background Art

[0002] Energy is the foundation for the survival and development of modern society. The supply capacity of energy is related to the sustainable development of the national economy and is one of the foundations of national strategic security. With the rapid development of my country's economy and society, the consumption of oil resources is also growing rapidly, and the dependence on foreign oil is getting higher and higher. At the same time, the greenhouse effect caused by the large-scale use of fossil fuels has made it increasingly important to seek clean renewable energy.

[0003] Biomass pyrolysis is one of the ways to effectively utilize biomass energy, and its product, biomass oil, is a material that can replace fossil energy. Biomass oil is a mixture of water and complex oxygen-containing organic matter, and contains a small amount of solid particle impurities. More than 300 types of organic matter have been detected. The large amount of oxygen content (40% to 50%) is the main reason why biomass oil and fossil fuels are completely different in chemical composition and physical properties.

[0004] Patent document with publication number CN116987520A A biomass thermal cracking oil production temperature control device uses a fan 10 to supply air at 15,000 cubic meters per hour → combustion horizontal bed 1 (combustion horizontal bed 1 uses the non-condensable gas generated during the operation of the equipment to supplement the combustion when the combustion temperature does not reach 830°C, and the produced bio-oil is used for supplementary combustion. The temperature control range of the entire equipment is within 5°C) → high temperature enters the combustion vertical bed 2 with a temperature of about 650°C (wind speed 23 meters, using wind speed and thermal expansion principles to circulate and heat the heat carrier) → vertical bed top cover 3 temperature is 560 degrees (heat carrier and carbon powder are separated). → upper heat carrier chamber 4 temperature is about 555 degrees → reaction chamber 5 temperature is 525°C (heat carrier is mixed with the top biomass silo for cracking reaction) → lower heat carrier chamber 6 temperature is 460°C (gas and carbon powder after the free fall reaction of the heat carrier enter the secondary separation system) → heat carrier separation chamber 7 (carbon powder is separated again, and the heat carrier enters the combustion vertical bed 2 for cyclic heating).

[0005] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0006] In the process of recovering heat from the existing biomass thermal cracking oil production, a fan is used to blow air to the combustion bed, and the expansion principle is used to circulate and heat the heat carrier, so that the heat carrier is mixed with the top biomass silo for feeding into the cracking reaction. In this process, the fan air supply specifications remain unchanged. When the temperature of the combustion bed is too high or the wind speed is too high, it is difficult to keep the ambient temperature in the equipment within a reasonable range. Summary of the invention

[0007] In order to overcome the deficiency in the existing biomass thermal cracking oil production process that the fan air distribution specifications remain unchanged, and when the temperature of the combustion bed is too high or the wind speed is too high, it is difficult to keep the ambient temperature in the equipment within a reasonable range, the embodiment of the present application provides a buffer tank for biomass liquefaction, which uses a first electric actuator to control the control bar to drive the air control block to move toward the bottom inside the first air outlet duct, so that part of the wind transported from the air inlet pipe to the inside of the air inlet duct flows out from the gap between the air guide block and the air control block, which can gradually reduce the bio-oil on the combustion bed while reducing the air volume transported to the inside of the air outlet pipe through the second air outlet and the transfer pipe, so as to achieve the effect of accurately controlling the overall temperature of the combustion bed.

[0014] In one possible implementation, an air duct is processed on the top of one side of the truncated cone tube, and an air inlet duct is processed inside one end of the buffer tank body. The outer diameters of the air duct and the air inlet duct are the same, and one end of the air duct is in contact with the surface of one end of the air inlet duct.

[0015] In one possible implementation, the outer wall of one end of the air duct is processed with a second tile, and the outer wall of one end of the air inlet duct is processed with a first tile. The first tile and the second tile are arranged opposite to each other, and the inner wall of one end of the second tile is in contact with the outer wall of the air inlet duct, and the inner wall of one end of the first tile is in contact with the outer wall of the air duct.

[0024] Third, in this scheme, when the wind flows out from the gap between the air guide block and the air control block, the second electric actuator is started to control the blocking block to move toward the top between the pressure relief pipe and the cylindrical riser, so that the branch pipe on the regulating support is connected with the inside of the cylindrical riser, and the wind from the air inlet pipe to the inside of the air inlet duct and flowing out from the gap between the air guide block and the air control block can be guided out from the inside of the cylindrical riser.

[0040] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0041] Embodiment 1:

[0042] This embodiment introduces a specific structure of a buffer tank for biomass liquefaction. Figure 1-Figure 9 As shown, it includes a buffer tank body 3, a regulating support 8 disposed inside one end of the buffer tank body 3, and an air inlet 9 disposed on one side of the regulating support 8 and located inside the buffer tank body 3, an air outlet pipe 4 is processed inside the other end of the buffer tank body 3, an air inlet 9 is processed on the top of the regulating support 8, a first air outlet 10 is processed on the bottom of the regulating support 8, a second air outlet 11 is processed on one side of the regulating support 8, and the air inlet 9 and the first air outlet 10 are slidably connected to the same air control member 13;

[0043] like Figure 3 , Figure 4 and Figure 7 The wind control member 13 includes a wind guide block 1302 and a wind control block 1301. The bottom of the wind guide block 1302 is assembled and fixed to the regulating support 8. The top of one side of the wind control block 1301 is pin-connected with a control strip 15. A support rod 20 is processed inside one end of the control strip 15. The outside of the support rod 20 is hingedly connected to the first electric actuator 14.

[0044] Among them, by making the first air outlet 10, the second air outlet 11 and the air inlet 9 interconnected, the air guide block 1302 and the air control block 1301 are formed by cutting a cylinder, and the cutting surface is an inclined surface. When the bottom of one side of the air guide block 1302 fits with the top of one side of the air control block 1301, the air transported from the air inlet pipe 2 to the inside of the air inlet 9 can be transported to the inside of the air outlet pipe 4 through the second air outlet 11 and the adapter pipe 6;

[0045] At the same time, when the first electric actuator 14 controls the control strip 15 to move toward the bottom, so that the control strip 15 drives the air control block 1301 to move toward the bottom inside the first air outlet 10, the surface of the air control block 1301 is separated from the surface of the air guide block 1302, so that part of the wind transported from the air inlet pipe 2 to the inside of the air inlet 9 flows out from the gap between the air guide block 1302 and the air control block 1301, so as to reduce the amount of air transported to the inside of the air outlet pipe 4 through the second air outlet 11 and the adapter pipe 6;

[0046] like Figure 2 and Figure 3 As shown, the adapter pipe 6 includes a cylindrical transverse pipe 601, one end of the cylindrical transverse pipe 601 is processed with a truncated cone pipe 602, the top of one side of the truncated cone pipe 602 is processed with an air inlet pipe 603, the inside of one end of the buffer tank body 3 is processed with an air inlet pipe 2, the outer wall of one end of the air inlet pipe 603 is processed with a second tile 22, and the outer wall of one end of the air inlet pipe 2 is processed with a first tile 21;

[0047] Among them, by inserting one end of the cylindrical transverse tube 601 into the interior of one end of the air outlet pipe 4, and buckling one side of the truncated cone tube 602 onto the exterior of the regulating support 8, after the truncated cone tube 602 and the regulating support 8 are fixed by bolts, the gap between the inner wall of the truncated cone tube 602 and the outer surface of the regulating support 8, as well as the gap between the surface of one end of the cylindrical transverse tube 601 and one end of the air outlet pipe 4 can be eliminated;

[0048] At the same time, the first tile 21 and the second tile 22 are arranged opposite to each other, and the outer diameters of the air duct 603 and the air inlet pipe 2 are set to be the same. When the truncated cone tube 602 is installed inside the buffer tank body 3, and one end of the air duct 603 is fitted with the surface of one end of the air inlet pipe 2, the inner wall of one end of the second tile 22 can be fitted with the outer wall of the air inlet pipe 2, and the inner wall of one end of the first tile 21 can be fitted with the outer wall of the air duct 603, so as to avoid air leakage in the gap between the surface of one end of the air inlet pipe 2 and the surface of one end of the air duct 603.

[0049] Secondly, in order to facilitate the fixing of the first electric actuator 14 inside the regulating support 8, the air control block 1301 is controlled by the control bar 15 to move up and down inside the first air outlet 10, such as Figure 7 and Figure 8 As shown, a mounting notch 23 is processed on one side of the regulating support 8, a threaded rod 24 is processed on the inner wall of one side of the mounting notch 23, and a nut 25 is threadedly connected to one end of the threaded rod 24. By hingedly connecting one end of the first electric actuator 14 to the outside of the threaded rod 24 and positioning the end between the nut 25 and the inner wall of one side of the mounting notch 23, one end of the first electric actuator 14 is restricted from being separated from the outside of the threaded rod 24, so that the first electric actuator 14 can control the control strip 15 inside the mounting notch 23 to drive the air control block 1301 to move up and down inside the first air outlet 10;

[0050] Furthermore, in order to facilitate the fixing of the transfer pipe 6 and the regulating support 8 inside the buffer tank body 3, as shown in FIG. Figure 2 and Figure 3 As shown, one side of the regulating support 8 is assembled and connected with the buffer tank cover 1. By buckling one side of the buffer tank cover 1 to the outside of one end of the buffer tank body 3 and fixing the buffer tank cover 1 to the buffer tank body 3 on all sides with bolts, the adapter pipe 6 and the regulating support 8 can be stably installed inside the buffer tank body 3, so that wind can flow from the air inlet pipe 2 through the inside of the regulating support 8 to the inside of the adapter pipe 6.

[0051] Embodiment 2:

[0052] Based on Example 1, this example introduces the specific structure of the regulating support 8. A branch pipe is processed at the bottom of the regulating support 8. A storage slot 7 is opened on one side of the bottom of the truncated cone tube 602. A cylindrical vertical tube 604 is processed at the middle of the cylindrical horizontal tube 601. A pressure relief pipe 17 is processed at the middle outer wall of the buffer tank body 3. A blocking block 12 is slidably connected between the cylindrical vertical tube 604 and the pressure relief pipe 17. The inside of the blocking block 12 is assembled and connected to the second electric actuator 16. The outside of one end of the pressure relief pipe 17 is assembled and connected to a support sleeve 19. The inside of the support sleeve 19 is processed with a horizontal plate 18.

[0053] Among them, a limiting groove 5 is processed on the inner wall of one end of the buffer tank body 3, and by making one end surface of the cylindrical vertical pipe 604 fit with the bottom inner wall of the limiting groove 5, after the regulating support 8 and the transfer pipe 6 are installed inside the buffer tank body 3, the branch pipe on the regulating support 8 is plugged into the inside of the cylindrical vertical pipe 604, so that the wind blown out from the inside of the first air outlet 10 by the regulating support 8 can enter between the cylindrical vertical pipe 604 and the pressure relief pipe 17, so that the blocking block 12 can be controlled to move up and down by the second electric actuator 16 to control the wind to flow out from the outside of the pressure relief pipe 17 or to flow into the inside of the cylindrical horizontal pipe 601 from the inside of the cylindrical vertical pipe 604;

[0054] Secondly, in order to ensure that the regulating support 8 is not affected by the branch pipe at the bottom of the regulating support 8 when it is connected to the truncated cone tube 602, such as Figure 3 and Figure 7 As shown, one end of the branch pipe at the bottom of the regulating support 8 is located inside the receiving notch 7. When the regulating support 8 is connected to the truncated cone tube 602, the receiving notch 7 is used to provide an installation space for the regulating support 8, so that the inner wall of the truncated cone tube 602 can be in contact with the surface of the regulating support 8.

[0055] Furthermore, by assembling one end of the second electric actuator 16 to be connected to the top of the horizontal plate 18, when the second electric actuator 16 controls the blocking block 12 to move toward the top between the pressure relief pipe 17 and the cylindrical riser 604, the upper branch pipe of the regulating support 8 is connected to the inside of the pressure relief pipe 17, so that the wind transported from the air inlet pipe 2 to the inside of the air inlet duct 9 and flowing out from the gap between the air guide block 1302 and the air control block 1301 can be guided out from the inside of the buffer tank body 3, thereby preventing the pressure inside the buffer tank body 3 from being too high, affecting the air volume of the wind transported from the air inlet pipe 2 to the inside of the air inlet duct 9 and transported to the inside of the air outlet pipe 4 through the second air outlet duct 11 and the transfer pipe 6;

[0056] At the same time, when the second electric actuator 16 controls the blocking block 12 to move toward the top between the pressure relief pipe 17 and the cylindrical riser 604, the branch pipe on the regulating support 8 is connected to the inside of the cylindrical riser 604, and the wind can be transported from the air inlet pipe 2 to the inside of the air inlet duct 9, and the wind flowing out from the gap between the air guide block 1302 and the air control block 1301 is guided out from the inside of the cylindrical riser 604. By taking advantage of the difference in flow velocity during the convergence of the two winds, the speed of high-speed flowing wind can be reduced. While ensuring the inconvenience of the air volume inside the cylindrical cross pipe 601, the overall flow velocity of the wind can be reduced, thereby controlling the air distribution volume delivered to the combustion cross bed in the prior art per unit time.

[0057] Specifically, when the biomass liquefaction buffer tank is used:

[0058] First, use bolts to fix one side of the air guide block 1302 to the inner wall of the first air outlet 10 from the inside of the installation slot 23, insert one end of the control strip 15 into the air control piece 13 at the bottom of one side of the air guide block 1302, and install the first electric actuator 14 between the support rod 20 on the control strip 15 and the threaded rod 24 on the side wall of the installation slot 23;

[0059] Then, the regulating support 8 is fixed to the truncated cone tube 602 on the transfer pipe 6, so that the inner wall of the truncated cone tube 602 fits with the surface of the regulating support 8, and the branch pipe at the bottom of the regulating support 8 is inserted into the inside of the cylindrical standpipe 604, and the regulating support 8 is connected and fixed to the buffer tank cover 1 at the same time;

[0060] Next, the buffer tank cover 1 is installed to one end of the buffer tank body 3, so that one end of the cylindrical horizontal pipe 601 on the adapter pipe 6 is inserted into the inside of the air outlet pipe 4, and one end of the cylindrical vertical pipe 604 on the adapter pipe 6 is moved to the top of the pressure relief pipe 17 through the inside of the limiting groove 5, so that the second electric actuator 16 supported and installed by the horizontal plate 18 drives the blocking block 12 to extend into the inside of the cylindrical vertical pipe 604 through the pressure relief pipe 17;

[0061] At the same time, the air induction pipe 603 at the top of one side of the truncated cone pipe 602 is connected to the air inlet pipe 2, and the second tile 22 and the first tile 21 are buckled between the air inlet pipe 2 and the air induction pipe 603 to block the gap between the air inlet pipe 2 and the air induction pipe 603, so that the wind transported from the air inlet pipe 2 to the inside of the air inlet duct 9 can be transported to the inside of the air outlet pipe 4 through the second air outlet duct 11 and the transfer pipe 6;

[0062] When the buffer tank body 3 is connected between the fan and the combustion horizontal bed of the existing biomass thermal cracking oil production, the wind configured by the fan flows to the inside of the regulating support 8 through the air inlet pipe 2 and the air duct 603, and the first electric actuator 14 is started to control the control bar 15 to drive the inclined surface on one side of the air control block 1301 to fit the inclined surface on one side of the air guide block 1302, so that the wind completely flows to the inside of the second air outlet 11 through the air inlet duct 9, and finally distributes the wind to the inside of the combustion horizontal bed through the inside of the truncated cone tube 602, the cylindrical horizontal tube 601 and the air outlet pipe 4;

[0063] When the combustion horizontal bed area is monitored by the existing temperature monitoring technology and the temperature is too high due to combustion, the existing bio-oil replenishment amount is reduced, and the first electric actuator 14 is started to control the control bar 15 to drive the air control block 1301 to move toward the bottom inside the first air outlet 10, so that part of the wind transported from the air inlet pipe 2 to the inside of the air inlet 9 flows out from the gap between the air guide block 1302 and the air control block 1301, reducing the amount of air transported to the inside of the air outlet pipe 4 through the second air outlet 11 and the transfer pipe 6, which can cooperate with the gradually reduced bio-oil to reduce the overall temperature of the combustion horizontal bed;

[0064] At the same time, by starting 16 to control the blocking block 12 to move toward the top between the pressure relief pipe 17 and the cylindrical standpipe 604, the upper branch pipe of the regulating support 8 is connected with the inside of the pressure relief pipe 17, so that the wind transported from the air inlet pipe 2 to the inside of the air inlet duct 9 and flowing out from the gap between the air guide block 1302 and the air control block 1301 can be guided out from the inside of the buffer tank body 3, so as to avoid excessive pressure inside the buffer tank body 3, which affects the air volume of the wind transported from the air inlet pipe 2 to the inside of the air inlet duct 9 and transported to the inside of the air outlet pipe 4 through the second air outlet duct 11 and the transfer pipe 6;

[0065] In addition, the second electric actuator 16 can be started to control the blocking block 12 to move toward the top between the pressure relief pipe 17 and the cylindrical riser 604, so that the branch pipe on the regulating support 8 is connected to the inside of the cylindrical riser 604, and the wind delivered from the air inlet pipe 2 to the inside of the air inlet duct 9 and flowing out from the gap between the air guide block 1302 and the air control block 1301 can be guided out from the inside of the cylindrical riser 604. By taking advantage of the difference in flow velocity during the convergence of the two winds, the speed of high-speed flowing wind can be reduced. While ensuring the inconvenience of the air volume inside the cylindrical cross pipe 601, the overall flow velocity of the wind can be reduced, thereby controlling the air distribution volume delivered to the combustion horizontal bed in the prior art per unit time, so as to adjust the combustion efficiency of the biological raw materials on the combustion horizontal bed, thereby regulating the temperature in the environment surrounding the combustion horizontal bed.

[0066] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
