Description

Technical Field

[0001] This invention relates to the field of biomass liquid fuel production technology, and in particular to a purification device for biomass liquid fuel processing. Background Technology

[0002] In the process of biomass liquid fuel processing, in order to remove impurities from the liquid fuel and improve its quality, it is usually necessary to purify the biomass liquid fuel. In order to facilitate the purification of biomass liquid fuel, workers usually use purification equipment to meet application standards and ensure safe use. Existing purification equipment usually consists of a distillation tank, a water bath, an exhaust pipe and a condenser.

[0003] For example, utility model patent application number CN202022559773.7 discloses a dehydration and purification device for alcohol-based fuels, specifically including a tank body. A motor is fixedly installed in the middle of the top of the tank body. A feeding pipe is inserted and connected to one side of the top of the tank body. A pipe cap is threaded onto the top of the feeding pipe. A rotating shaft is installed inside the tank body, and the top of the rotating shaft is fixedly connected to the output shaft of the motor. Several stirring blades are fixedly installed at equal intervals on the bottom of both sides of the rotating shaft. A water bath chamber is opened at the bottom of the tank body wall. Electric heating plates are fixedly installed on both sides inside the water bath chamber. The beneficial effects of this utility model are: water bath heating can be carried out through the water bath chamber opened in the tank body wall, which facilitates the control of heating temperature and improves the purification effect; the motor can drive the stirring blades to stir and heat, resulting in more uniform heating; and the heat exchange area can be increased through several water bath pipes. The combination of several water bath pipes and stirring blades can further improve the uniformity of heating, thereby improving the purification effect and efficiency.

[0004] However, biomass liquid fuel feedstocks usually contain some natural emulsifiers. These components enter the liquid fuel during the purification process. They have both hydrophilic and lipophilic properties and can form a protective film at the oil-water interface, preventing the coalescence of oil and water droplets. This makes it difficult for oil and water to separate quickly, thus prolonging the separation time during the purification process, reducing purification efficiency, and making it inconvenient to use. Summary of the Invention

[0005] In view of this, the present invention provides a purification device for biomass liquid fuel processing, comprising a disc spring, a first sliding plate, a second sliding plate, and a fixed spring that can disrupt the emulsification effect during the purification process. As the transmission shaft rotates, it drives a mixing impeller to rotate, accelerating the heat exchange of the biomass liquid fuel and causing it to heat up faster. During the rotation of the transmission shaft, a control cam rotates, pressing a control push plate. This push plate then pushes the second sliding plate within the first sliding plate, compressing the fixed spring. The control cam's profile is larger than the length of the second sliding plate. This ensures that after the control cam presses the second sliding plate into the first sliding plate, its continued rotation pushes the first sliding plate within the fixed seat, compressing the disc spring. After the control cam protrudes away, the first sliding plate returns to its original position with the rebound of the disc spring, and simultaneously, the second sliding plate returns to its original position with the rebound of the fixed spring, creating high-frequency reciprocating oscillations to break the emulsion of the biomass liquid raw material.

[0007] Furthermore, a water injection pipe is fixedly connected to the outside of the distillation and purification tank; the water outlet of the water injection pipe is located inside the heating chamber; multiple sets of electric heating plates are fixedly connected inside the heating chamber; the multiple sets of electric heating plates are arranged in a ring array inside the heating chamber; the drain pipe is arranged in an alternating pattern with the multiple sets of electric heating plates; and a one-way valve is provided on the outside of the water injection pipe.

[0008] Furthermore, a first gas supply pipe is fixedly connected to the outlet end of the first condenser; a three-way connector is fixedly connected to the end of the first gas supply pipe; a reflux pipe is fixedly connected to the lower part of the three-way connector; the outlet end of the reflux pipe is located inside the distillation purification tank; and a check valve is installed at the lower part of the reflux pipe.

[0009] Furthermore, a second gas supply pipe is fixedly connected to the right side of the three-way connector; the gas outlet of the second gas supply pipe is connected to the inlet end of the second condenser; a drain pipe is fixedly connected to the outlet end of the second condenser; a second control check valve is fixedly connected to the upper part of the return pipe; and a first control check valve is fixedly connected to the left side of the second gas supply pipe.

[0010] Furthermore, the lower part of the distillation and purification tank is fixedly connected to multiple sets of heat exchange tubes communicating with the heating chamber; the multiple sets of heat exchange tubes are respectively staggered with multiple sets of mixing and stirring paddles and three sets of fixed seats.

[0011] Furthermore, disc springs are fixedly connected to the outer sides of all three sets of limiting slide plates; the ends of the three sets of disc springs are fixedly connected to the three sets of fixed seats; and a first sliding plate is fixedly connected to the outer side of all three sets of limiting slide plates.

[0012] Furthermore, each of the multiple sets of first sliding plates is slidably connected to a second sliding plate; each of the multiple sets of second sliding plates is fixedly connected to a fixing spring on its outer side; the ends of the three sets of fixing springs are respectively fixedly connected to the three sets of first sliding plates; each of the three sets of first sliding plates is fixedly connected to a control push plate on its outer side; and the transmission shaft is fixedly connected to three control cams on its outer side; the three control cams are respectively aligned with the positions of the three sets of control push plate fixing seats.

[0013] Furthermore, the upper first sliding plate has multiple sets of hemispherical protrusions fixedly connected to its exterior; the middle first sliding plate has multiple sets of sawtooth protrusions fixedly connected to its exterior; and the lower first sliding plate has multiple sets of corrugated surfaces on its exterior.

[0014] Furthermore, each of the three sets of first sliding plates is fixedly connected to a set of turbulence pushers; all sets of turbulence pushers are inclined at a 45-degree angle.

Beneficial effects

[0016] During use, the rotating mixing paddle causes the transmission shaft to drive the control cam to rotate. This rotation of the control cam compresses the control push plate, which in turn pushes the second sliding plate within the first sliding plate, compressing the fixing spring. After the second sliding plate is pressed into the first sliding plate, the continued rotation of the control cam continues to push the first sliding plate within the fixed seat, compressing the disc spring. When the control cam protrudes away, the first sliding plate returns to its original position with the rebound of the disc spring, and simultaneously, the second sliding plate returns to its original position with the rebound of the fixing spring, creating a high-frequency reciprocating oscillation. As the first and second sliding plates reciprocate and penetrate the liquid during this oscillation, instantaneous shear stress is generated on the emulsion droplets. When the stress exceeds the interfacial film strength, the droplets rupture and coalesce, destroying the interfacial film. This enhances mass and heat transfer, suppresses secondary emulsification, accelerates purification, ensures purification stability, and effectively improves the practicality of the purification device.

[0017] The turbulence pusher can generate an oblique thrust on the liquid when the first sliding plate oscillates, forming a spiral shear flow. At the same time, when the inclined turbulence pusher comes into contact with the emulsion, it can generate both horizontal and vertical impact forces, further improving the demulsification effect. Furthermore, the inclined turbulence pusher can convert the linear motion of the sliding seat into an oblique thrust on the liquid, improving the oscillation effect and effectively enhancing the convenience of the purification device.

[0018] The hemispherical protrusions on the upper first sliding plate prevent light oil from agglomerating into a film, the serrated protrusions on the middle first sliding plate tear the emulsion core, and the corrugated surface on the lower first sliding plate evenly shears the liquid, further improving the demulsification effect and increasing the purification efficiency of biomass liquid fuel.

[0043] The specific usage and function of this embodiment: In the process of purifying biomass liquid fuel, the biomass liquid fuel to be purified is injected into the distillation purification tank 1 through the feed pipe 103. Then, water is injected into the heating chamber 107 through the water injection pipe 108, and the electric heating plate 109 is activated to heat the water in the heating chamber 107. As the temperature of the water in the heating chamber 107 rises, it can heat the biomass liquid fuel in the distillation purification tank 1, thus distilling and purifying the biomass liquid fuel in the distillation purification tank 1. As the temperature of the biomass liquid fuel in the distillation purification tank 1 rises, the biomass liquid fuel will evaporate into steam. After the biomass liquid fuel is injected, the feed pipe 103 is sealed with a sealing cap. At this time, the distillation purification tank 1 is in a closed state, which allows the vapor evaporated from the biomass liquid fuel to flow through the inlet pipe 114 to the first condenser 113, where the first condenser 113 condenses the vapor into liquid. The support column 102 supports the distillation purification tank 1. Water used is discharged through the drain pipe 110, and residual purified fuel is discharged through the fuel discharge pipe 111. The liquid condensed by the first condenser 113 flows back into the distillation purification tank 1 through the return pipe 121 for secondary purification of the biomass liquid fuel, improving the purification effect. When it is necessary to circulate and purify the biomass liquid fuel, the first control check valve 120 is closed and... When the second control check valve 122 is opened, the liquid condensed from the first condenser 113 can only flow back into the distillation purification tank 1 through the return pipe 121 for circulation purification. After purification, the first control check valve 120 is opened and the second control check valve 122 is closed. At this time, the condensed liquid will enter the second condenser 117 through the second gas supply pipe 118 for secondary condensation and then be discharged through the drain pipe 119. The purification effect of biomass liquid fuel can be judged by sensing the temperature of the biomass liquid fuel vapor with a temperature sensor. The first control check valve 120 and the second control check valve 122 are opened or closed according to the purification effect. This method is commonly used by those skilled in the art. The technical means are not described in detail in this application. The heat exchange tube 112 increases the heat exchange effect between biomass liquid fuel and heating water, accelerating the formation of biomass liquid fuel steam. During the heating of the biomass liquid fuel, the drive motor 104 is started, causing the drive motor 104 to drive the transmission shaft 105 to rotate. The rotation of the transmission shaft 105 drives the mixing impeller 106 to rotate, accelerating the heat exchange effect of the biomass liquid fuel and causing it to heat up faster. During the rotation of the transmission shaft 105, the control cam 131 rotates, pressing the control push plate 129.The control push plate 129 pushes the second sliding plate 128 to slide within the first sliding plate 126 and compress the fixing spring 130. The control cam 131 has a larger profile than the length of the second sliding plate 128. This means that after the control cam 131 presses the second sliding plate 128 into the first sliding plate 126, as the control cam 131 continues to rotate, it pushes the first sliding plate 126 to slide within the fixing seat 123 and compress the disc spring 125. After the protrusion of the control cam 131 moves away, the first sliding plate 126 returns to its original position with the rebound of the disc spring 125, while the second sliding plate 128 returns to its original position with the rebound of the fixing spring. The 130° rebound resets the flow, creating high-frequency reciprocating oscillations to break up the emulsion of the biomass liquid feedstock. The hemispherical protrusions on the upper first sliding plate 126 prevent light oil from agglomerating into a film. The serrated protrusions on the middle first sliding plate 126 tear apart the emulsion core. The corrugated surface on the lower first sliding plate 126 evenly shears the liquid. The turbulence-propelling plate 127 generates an oblique thrust on the liquid when the first sliding plate 126 oscillates, forming a spiral shear flow. Both the first condenser 113 and the second condenser 117 adopt a tubular structure, and the condensing medium is circulating water.

[0044] Example 2

[0045] Based on Example 1, please refer to Figures 3 to 4 As shown, it includes: fixed columns 132 and bubble-breaking cones 133. The upper part of the transmission shaft 105 is fixedly connected with four fixed columns 132 in a ring array. The outside of the multiple sets of fixed columns 132 is fixedly connected with multiple sets of bubble-breaking cones 133 in a ring array. The four fixed columns 132 are all set on the upper part of three sets of fixed seats 123. The four fixed columns 132 are all aligned with the position of the air intake pipe 114.

[0046] The specific usage and function of this embodiment: In this invention, during the rotation of the transmission shaft 105, the fixed column 132 will be driven to rotate. During the rotation of the fixed column 132, the bubble-breaking cone 133 will puncture the bubbles in the steam to prevent the bubbles from carrying liquid into the first condenser 113.
