Description

Technical Field

[0001] The invention relates to the technical field of flash evaporators, in particular to a biodiesel heating flash evaporation device. Background Art

[0002] Flash evaporation is a phenomenon in which a high-pressure saturated liquid enters a relatively low-pressure container and, due to the sudden drop in pressure, the saturated liquid becomes saturated vapor and saturated liquid at a portion of the container's pressure. Flash evaporation equipment usually refers to flash dryers, which are devices that utilize the difference in saturated vapor pressure of a substance at different pressures to rapidly evaporate the liquid by reducing the pressure, thereby achieving gas-liquid separation.

[0003] Biodiesel is a renewable and environmentally friendly liquid fuel. It is mainly made from oil crops (such as soybeans, rapeseed, cotton, palm, etc.), wild oil plants, aquatic plant oils such as engineered microalgae, as well as animal fats, catering waste oil, etc. through ester exchange or thermochemical processes. It can replace or be blended with traditional petrochemical diesel. The preparation process of biodiesel mainly includes raw material pretreatment, ester exchange reaction, glycerol separation, product refining and other stages. Among them, flash dryers are used to remove low-component substances and water vapor in the dehydration and product separation stages.

[0004] Biodiesel raw materials (such as animal and vegetable oils, waste cooking oil, etc.) have a high viscosity. During the flash drying process, when the material temperature falls below its softening point or the operating pressure fluctuates, a sticky adhesion layer easily forms on the surface of the crushed pieces. This adhesion phenomenon can lead to multiple negative effects: first, the surface roughness of the crushed pieces increases, reducing the effective contact area between the material particles and the crushing elements, thereby reducing crushing efficiency; second, the thermal conductivity of the adhesion layer is significantly lower than that of the metal substrate, forming an insulating barrier that weakens the heat transfer efficiency during the flash drying process; third, as the thickness of the adhesion layer increases, the dynamic balance performance of the crushing elements decreases, equipment vibration intensifies, and the service life of mechanical components is shortened. Existing flash drying equipment alleviates this problem by increasing the ambient temperature or the crushing frequency, but high temperatures can easily cause thermal degradation of the material, while mechanical strengthening methods lead to increased energy consumption and noise pollution. Therefore, these devices do not meet existing needs. To address this issue, we have proposed a biodiesel heating flash evaporation device. Summary of the Invention

[0014] As an optional solution of a biodiesel heating flash evaporation device described in the present invention, an intermittent pressure relief component is provided in the crushing block, and the intermittent pressure relief component is used to intermittently relieve the high pressure generated by heating in the heat collection tank.

[0016] As an optional solution of a biodiesel heating flash evaporation device described in the present invention, the swing gear is meshedly connected to a drive rack, the top of the drive rack is fixedly connected to a slider, the slider is slidably connected in a track groove, and the track groove is opened in the crushing block.

[0017] The present invention has the following beneficial effects:

[0018] 1. This biodiesel heating flash evaporation device recovers and reuses the waste heat resources in the flash evaporator shell by setting a heat collection component in the crushing block, thereby improving the thermal energy utilization efficiency of the device. The collaborative design of the heat collection tank and the heat conduction fan allows the heat of the high-temperature airflow in the hot air output channel to be actively captured by the annular heat collection plate, and the heat is directed to the surface of the crushing block through the rotating heat conduction fan, forming a continuous local heating effect. This design effectively prevents the oily substances in the biodiesel raw material from adhering to the crushing block during the crushing process, thereby maintaining the structural integrity and functional stability of the crushing block. The constant temperature state of the crushing block can ensure that the raw material particles are always in the optimal thermodynamic conditions during crushing. In long-term operation, this design can also reduce the frequency of shutdowns and cleaning caused by material adhesion, extend the service life of the equipment, reduce maintenance costs, and provide reliable guarantees for the continuous production of biodiesel.

[0019] 2. The biodiesel heating flash evaporation device solves the problem of pressure accumulation caused by continuous heat storage in the heat collecting tank through the linkage of the pressure relief block and the pressure relief spring. When the internal pressure exceeds the set threshold, the pressure relief block moves upward under the drive of the pressure difference, so that the closed channel and the pressure relief channel are instantly connected, and the high-pressure gas is quickly released to the external environment; after the pressure is balanced, the pressure relief spring automatically resets the seal to ensure that the heat collecting tank returns to a closed state. This dynamic pressure regulation mode has dual advantages: on the one hand, intermittent pressure relief can prevent the broken blocks from being subjected to high-pressure stress for a long time and prevent the occurrence of material fatigue cracks; on the other hand, the short pressure relief process releases pressure while precisely controlling the pressure relief duration, allowing only a small amount of heat to be lost, ensuring that the surface temperature of the broken blocks does not fluctuate too much, effectively maintaining the critical temperature range required for its anti-adhesion, and perfectly balancing the contradiction between temperature stability and pressure safety while ensuring the durability of the equipment.

[0020] 3. This biodiesel flash heating unit achieves a step-change improvement in hot air energy capture efficiency through the innovative structural design of its oscillating heat collection and transfer assembly. The second heat absorbing plate, mechanically coupled to the track groove and drive rack, oscillates periodically at a constant frequency, expanding its effective heating area compared to a static structure. When the second heat absorbing plate swings outward, its deployed fins intercept more hot air flow, increasing the heat absorption rate. During the inward swing, the accumulated heat is efficiently transferred to the first heat absorbing plate through physical contact. This dynamic heat absorption mechanism accelerates heat storage in the heat collection tank and allows the crushing block surface to quickly reach operating temperature after startup, significantly reducing preheating time compared to traditional designs. Furthermore, the airflow disturbance caused by the oscillation disrupts the laminar boundary layer within the hot air output channel, enhancing turbulence and improving overall heat transfer efficiency. This assembly not only significantly accelerates the equipment's transition to steady-state operation but also reduces the risk of local overheating by optimizing heat distribution, keeping the temperature uniformity of the crushed blocks within a certain range and providing an ideal thermal environment for the refined drying of biodiesel feedstock.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1: This example aims to solve the problem of grease adhering to the surface of the crushing block 24, which leads to a decrease in crushing efficiency. Figures 1 to 8 A biodiesel heating flash evaporation device includes a flash evaporation device 1, which includes a flash evaporator shell 11. A crushing device 2 is installed in the flash evaporator shell 11. The crushing device 2 includes a crushing rotating disk 23, and a crushing block 24 is installed on the crushing rotating disk 23. A heat collecting component 4 is installed in the crushing rotating disk 23 and the crushing block 24.

[0032] A feed pipe 12 and a heating pipe 14 are provided on the side wall of the flash evaporator shell 11 . A feed screw 13 is provided in the feed pipe 12 . An air suction device 15 is provided on the top of the flash evaporator shell 11 .

[0033] The crushing device 2 includes a crushing installation shell 21 installed in the flash evaporator shell 11, a crushing rotating disk 23 is installed in the crushing installation shell 21, a driving motor 22 is installed at the bottom of the crushing rotating disk 23, and crushing blocks 24 are installed on the side walls of the crushing rotating disk 23. A hot air output channel 25 is opened in the crushing rotating disk 23 and the crushing blocks 24.

[0034] During the preparation of biodiesel, a series of pretreatment processes such as drying are first required to prepare for subsequent processes. Flash evaporation equipment 1 is usually used for drying the raw materials. The raw materials enter the flash evaporator shell 11 through the feed pipe 12 and feed screw rod 13 of the flash evaporation equipment 1. A heating pipe 14 transports hot air into the flash evaporator shell 11. At the same time, the suction device 15 at the top changes the air pressure in the flash evaporator shell 11. The low boiling point characteristic of the low pressure state achieves rapid drying. The crushing device 2 is used to crush the raw material particles to increase the contact area between the raw material and the hot air and improve the drying efficiency. Under the action of the suction device 15, the crushed and dried raw materials are transported from the top to the collection equipment for subsequent processing (the above structure and principle are existing technologies, so this solution will not be described in detail).

[0035] The heat collection assembly 4 includes a heat collection tank 46 disposed in the crushing block 24 . The heat collection tank 46 is used to collect heat and store it to heat the crushing block 24 .

[0036] A rotating assembly 3 is provided in the crushing rotating disk 23. The rotating assembly 3 includes an I-shaped groove 31 opened in the crushing rotating disk 23. An I-shaped rotating block 32 is rotatably connected in the I-shaped groove 31. A No. 1 gear 34 is provided at the bottom of the I-shaped rotating block 32. The No. 1 gear 34 is meshed with an annular tooth groove 33. The annular tooth groove 33 is opened in the crushing mounting shell 21.

[0037] A No. 1 ring groove 35 and a No. 2 ring groove 38 are provided in the I-shaped rotating block 32. An annular heat collecting plate 36 is installed in the No. 1 ring groove 35, and a heat collecting guide annular block 37 is installed in the No. 2 ring groove 38. One side of the heat collecting guide annular block 37 is connected to the annular heat collecting plate 36, and the other side of the heat collecting guide annular block 37 is fixedly connected to the No. 1 heat absorbing plate 39. The No. 1 heat absorbing plate 39 is arranged on the inner side of the heat collecting guide annular block 37.

[0038] The heat collecting assembly 4 includes a heat conducting groove 41 provided in the I-shaped rotating block 32, a mounting rod 42 is installed in the heat conducting groove 41, a heat conducting fan 43 is installed in the mounting rod 42, the blades of the heat conducting fan 43 are arranged below the heat conducting groove 41, the blades of the heat conducting fan 43 are located above the annular heat collecting plate 36, and the heat conducting groove 41 is connected to the heat collecting groove 46.

[0039] A fan gear 44 is fixedly connected to the top of the heat-conducting fan 43 . The fan gear 44 is meshedly connected to a second gear 45 . The second gear 45 is disposed in a heat collecting tank 46 .

[0040] The heat collecting tank 46 is designed to concentrate part of the heat in the flash evaporator shell 11 in the crushing block 24. This design can increase the surface temperature of the crushing block 24, thereby preventing the oily substances from easily adhering to the surface of the crushing block 24, thereby ensuring the cleanliness of the crushing block 24.

[0041] As the driving motor 22 is driven, the crushing rotating disk 23 starts to rotate in the crushing installation shell 21. At this time, the I-shaped rotating block 32 installed in the crushing rotating disk 23 starts to rotate in the I-shaped groove 31 under the drive of the annular tooth groove 33 and the No. 1 gear 34. A heat-conducting fan 43 is installed in the I-shaped rotating block 32. Since the crushing block 24 is fixedly installed on the surface of the crushing rotating disk 23, the I-shaped rotating block 32 rotates relative to the crushing block 24. Therefore, the heat-conducting fan 43 in the I-shaped rotating block 32 rotates relative to the fan gear 44 fixedly connected to the crushing block 24. Due to the meshing of the fan gear 44 and the No. 2 gear 45, and the engagement of the I-shaped rotating block 32 with the No. 2 gear 45, the heat-conducting fan 43 in the I-shaped rotating block 32 rotates relative to the fan gear 44 fixedly connected to the crushing block 24. 2 rotates, so the heat-conducting fan 43 starts to rotate, and an annular heat collecting plate 36, a heat-collecting guide annular block 37 and a heat-absorbing plate 39 are arranged below the heat-conducting fan 43. The heat-absorbing plate 39 is arranged in the hot air output channel 25 to receive the heat of the hot air passing through the hot air output channel 25, and transport it to the surface of the annular heat collecting plate 36 through the heat-collecting guide annular block 37. The heat is then transferred to the heat collecting tank 46 through the rotation of the heat-conducting fan 43. Through this design, the crushing block 24 can be continuously heated, thereby preventing oily substances from adhering to the surface of the crushing block 24, ensuring the cleanliness of the crushing block 24, and then ensuring the crushing effect of the device.

[0042] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8 An intermittent pressure relief component 5 is provided in the crushing block 24. The intermittent pressure relief component 5 is used to intermittently relieve the high pressure generated by heating in the heat collecting tank 46. The intermittent pressure relief component 5 includes a pressure relief channel 51 and a pressure relief mounting groove 52 opened in the crushing block 24. A pressure relief block 54 is slidably connected in the pressure relief mounting groove 52. A pressure relief spring 53 is installed between the pressure relief block 54 and the pressure relief mounting groove 52. A closed channel 55 is opened in the pressure relief block 54.

[0043] Since heat is continuously collected in the broken block 24, the pressure in the heat collection tank 46 will continue to increase. The broken block 24 is in a high-pressure state for a long time, which may damage the quality of the broken block 24 itself. Therefore, it is necessary to intermittently perform a pressure relief process on the broken block 24 through the intermittent pressure relief component 5. This process ensures the stability of the structure of the broken block 24 itself while ensuring the high temperature of the surface of the broken block 24.

[0044] When the temperature in the heat collecting tank 46 rises, the internal pressure continues to increase, which will drive the pressure relief block 54 to slide upward. After the pressure relief block 54 slides upward for a distance, the closed channel 55 in the pressure relief block 54 is connected to the pressure relief channel 51, and the pressure relief channel 51 is connected to the outside world. At this time, the high-pressure environment in the heat collecting tank 46 and the low-pressure environment outside are in contact with each other. The pressure in the heat collecting tank 46 will be quickly discharged outward through the closed channel 55 and the pressure relief channel 51, thereby alleviating the high pressure situation in the crushing block 24. When the internal pressure is the same as that of the outside world, the pressure relief block 54 slides downward through the action of the pressure relief spring 53, and the pressure relief channel 51 is re-blocked. At this time, the interior becomes a closed space again to avoid long-term contact with the external low-pressure environment, which causes the internal temperature to drop. The oily substance will adhere to the surface of the crushing block 24 under a low temperature environment. Therefore, through this intermittent pressure relief process, the stability of the structure of the crushing block 24 itself is guaranteed under the premise of ensuring the high temperature of the surface of the crushing block 24.

[0045] Example 3: This example is an explanation based on Example 2. For details, please refer to Figures 1 to 8 A swinging heat-collecting and conducting component 6 is provided in the hot air output channel 25. The swinging heat-collecting and conducting component 6 includes a mounting frame 61 mounted above the No. 1 heat-absorbing plate 39. A swinging gear 62 is mounted in the mounting frame 61. The side wall of the swinging gear 62 is fixedly connected to the No. 2 heat-absorbing plate 63. The No. 2 heat-absorbing plate 63 expands the contact area with the hot air by swinging.

[0046] The swing gear 62 is meshedly connected with a driving rack 64 , and a slider 65 is fixedly connected to the top of the driving rack 64 . The slider 65 is slidably connected in a track groove 66 , and the track groove 66 is opened in the crushing block 24 .

[0047] The design of the swing collection heat conduction component 6 is used to improve the efficiency of the No. 1 heat absorbing plate 39 absorbing heat from the hot air output channel 25. As mentioned above, the crushing block 24 rotates relative to the I-shaped rotating block 32, and the No. 2 heat absorbing plate 63 and the driving rack 64 are installed in the I-shaped rotating block 32. Therefore, when the I-shaped rotating block 32 rotates, the driving rack 64 rotates with the I-shaped rotating block 32, and a slider 65 is installed on the top of the driving rack 64. The slider 65 is slidably connected to the track groove 66 in the crushing block 24. Therefore, during the rotation of the I-shaped rotating block 32, the slider 65 and the driving rack 64 fixedly connected to the slider 65 are driven to slide up and down. Through this sliding, the swing gear 62 meshed with the driving rack 64 is driven to swing and rotate. It is fixedly connected to one side of the swing gear 62, so the No. 2 heat absorbing plate 63 will also continuously swing in the hot air output channel 25. When the No. 2 heat absorbing plate 63 swings outward, the contact area with the hot air flow will increase. When the No. 2 heat absorbing plate 63 swings inward, the heat in the No. 2 heat absorbing plate 63 is transferred to the No. 1 heat absorbing plate 39 through the mutual contact between the No. 2 heat absorbing plate 63 and the No. 1 heat absorbing plate 39, and then transported to the surface of the broken block 24. Through this design, the accumulation efficiency of heat energy in the heat collecting tank 46 can be improved, thereby ensuring the rate of temperature increase on the surface of the broken block 24, and thus quickly making the equipment work in a good state. At the same time, the airflow disturbance effect generated by the swing can break the laminar boundary layer in the hot air output channel 25, enhance the turbulence intensity, and improve the overall heat exchange efficiency.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
