Description

Technical Field

[0001] The invention relates to the technical field of fatty acid purification, in particular to a device and method for continuous separation and purification of crude fatty acids. Background Art

[0002] Fatty acids are important basic chemical raw materials and are widely used in industries such as rubber, plastics, textiles, washing, papermaking, medicine and food. Fatty acids are the simplest type of fat and are the components of many more complex fats. Fatty acids can be oxidized and decomposed into water and carbon dioxide in the presence of sufficient oxygen, releasing a large amount of energy. Therefore, fatty acids are one of the main energy sources of the body. Fatty acid production is made by heating oil with sulfuric acid and using a catalyst to first form crude fatty acids, which are then heated and dehydrated to form refined fatty acids. In the process of dehydrating crude fatty acids to form refined fatty acids, heating is an important condition. Vacuum distillation is the most common method for refining fatty acids. Its basic principle is to use the characteristic that the sublimation point of fatty acids is lower than their boiling point. The fatty acid sample is heated to its boiling temperature, and the components in the fatty acids are evaporated in turn according to the difficulty of volatilization. Then the steam is condensed back into liquid, and fatty acids with different melting points are collected at different temperatures. High boiling point impurities (i.e. residues) are separated and finally discharged from the bottom of the distillation kettle.

[0003] Announcement No. CN220834159U discloses a crude fatty acid refining and diverting device, which can greatly improve the separation effect of the mixture through the design of the screen cylinder and the stirring blades, wherein the larger impurities and particles are heated by the heating rod and stirred and broken by the stirring blades, which will be beneficial to the purification and separation of crude fatty acids. This design can reduce the labor cost and time cost of using the crude fatty acid refining and diverting device, and the condensation effect can be greatly improved through the mutual cooperation of the arched branch pipe, the shower head and the nozzle, wherein the arched branch pipe can effectively divert the connecting pipe, and the shower head and the nozzle can repeatedly spray the arched branch pipe to cool it down. In addition, the condensed water can be repeatedly utilized through the design of the circulating pump, which greatly improves the water-saving capacity of the crude fatty acid refining and diverting device, but the above patent still has the following problems in actual use: The crude fatty acid refining and diversion device can greatly improve the separation effect of the mixture through the design of the sieve drum and the stirring fan blades. However, since a certain amount of fatty acids will remain on the surface of the impurities, the impurities cannot be distilled, resulting in a waste of fatty acids. The impurities adhere to the sieve drum, causing the sieve drum to be blocked, which is not conducive to the continuous separation and purification of crude fatty acids.

[0004] Therefore, a device and method for continuous separation and purification of crude fatty acids are proposed to solve the above-mentioned problems. Summary of the invention

[0018] By adopting the above technical solution, the steam generated by distillation is introduced into the diverter through the air inlet pipe and the diverter and diverted into the diverter pipe. The spiral heat dissipation pipe can not only realize the condensation of steam, but also utilize the spiral structural characteristics of the spiral heat dissipation pipe to make the steam flow and drive the spiral heat dissipation pipe to rotate, thereby facilitating the heat dissipation of the spiral heat dissipation pipe.

[0019] Preferably, a combiner is fixedly installed at the end of the combining pipe, a support pipe is rotatably connected to the bottom center of the combiner, a third valve is fixedly installed at the end of the support pipe, a spiral plate is fixedly installed on the outside of the diverter, a support block is fixedly installed at the top center of the spiral plate, and a plurality of breaking up nails are fixedly installed on the top of the support block.

[0020] By adopting the above technical solution, high-pressure spray water impacts the support block and breaking pins on the top of the spiral plate.

[0022] By adopting the above technical solution, cold water is pumped into the interior of the atomizer and the spray ring through the water inlet pipe, and the spiral heat dissipation tube is cooled by continuously generating high-pressure spray water and water mist, thereby improving the effect of steam condensation. The high-pressure spray water impacts the spiral plate, causing the high-pressure spray water to generate a certain spiral force, thereby driving the diverter, diverter pipe, spiral heat dissipation tube, confluence pipe and confluence to rotate, thereby further improving the heat dissipation effect of the spiral heat dissipation tube.

[0023] The steps are as follows: Step 1: Inject the crude fatty acid into the mixing box through the feed pipe, and use the mixing motor to drive the mixing main gear to rotate. By utilizing the meshing connection between the mixing main gear, the mixing slave gear and the meshing gear ring, the self-rotation of the mixing slave gear and the revolution of the meshing gear ring can be realized. The supporting tripod and the first mixing auger are driven to rotate by the mixing main gear, and the meshing gear ring drives the second spiral cleaning blade to rotate and revolve at the same time, so as to fully mix the crude fatty acid.

[0024] Step 2: The mixed crude fatty acid enters the distillation box, and the crude fatty acid solution is preliminarily filtered through the filter mesh disk. The fixed ring and the first spiral cleaning blade are driven to rotate by rotating the connecting rod, and the impurities on the filter mesh disk are cleaned to the top of the guide cone block. The impurities are heated and distilled through the heating plate on the top of the guide cone block. The steam can be guided by setting a steam guide hood and a guide groove.

At the same time, cold water is pumped into the interior of the atomizer and the spray ring through the water inlet pipe. The high-pressure spray water impacts the spiral plate to make the high-pressure spray water generate a certain spiral force, thereby driving the diverter, diverter pipe, spiral heat dissipation pipe, confluence pipe and confluence to rotate, so as to dissipate the heat of the spiral heat dissipation pipe. At the same time, the high-pressure spray water impacts the support block and breaking pins on the top of the spiral plate.

The specific contents are as follows: 1. By setting up a mixed distillation mechanism, not only can the filter screen inside the distillation box be used to perform preliminary filtration on the crude fatty acid solution, but also, because the particle sizes of the filter screens are different and the particle size of the filter screen at the top is the largest, the crude fatty acid solution can be graded and filtered, and the fixed ring and the first spiral cleaning leaf are driven to rotate by rotating the connecting rod. The structural characteristics of the first spiral cleaning leaf can be used to clean the impurities on the filter screen to the top of the guide cone block, and the impurities are heated and distilled by the heating plate at the top of the guide cone block to avoid residual fatty acids on the surface of the impurities, thereby avoiding the phenomenon of fatty acid waste. By setting up a steam guide hood and a guide groove, the steam can be guided without steam backflow or residual phenomenon. The separation and purification effect of the crude fatty acid can be improved by the distillation method, and the stirring bracket at the bottom of the rotating connecting rod can be used to The filtered crude fatty acid solution is stirred, and the effect of crude fatty acid distillation is improved by a distillation heater. The guide cone block can be taken out from the bottom of the steam guide cover by a rotating plate at the bottom of the guide cone block, which is convenient for cleaning impurities on the surface of the guide cone block, thereby improving the effect of impurity distillation. By setting a mixing box, not only can the mixing motor be used to drive the mixing main gear to rotate, but also the meshing connection between the mixing main gear, the mixing slave gear and the meshing gear ring can be used to realize the self-rotation of the mixing slave gear. Since the meshing gear ring is fixedly installed inside the mixing box, the revolution of the meshing gear ring can be realized. The supporting tripod and the first mixing auger are driven to rotate by the mixing main gear, and the meshing gear ring drives the second spiral cleaning blade to rotate and revolve at the same time, thereby improving the mixing degree of crude fatty acids, and facilitating the separation and purification of crude fatty acids. 2. By setting up the condensation recovery mechanism, not only can the air inlet pipe and the diverter be used to introduce and divert the steam generated by distillation into the diverter pipe, but the spiral heat dissipation pipe can also realize the condensation of steam. At the same time, the spiral structural characteristics of the spiral heat dissipation pipe can be used to make the steam flow and drive the spiral heat dissipation pipe to rotate, which is convenient for the heat dissipation of the spiral heat dissipation pipe. At the same time, cold water is pumped into the interior of the atomizer and the spray ring through the water inlet pipe, and the spiral heat dissipation pipe is cooled by continuously generating high-pressure spray water and water mist, thereby improving the effect of steam condensation. The high-pressure spray water impacts the spiral plate, so that the high-pressure spray water generates a certain spiral force, thereby driving the diverter, the diverter pipe, the spiral heat dissipation pipe, the confluence pipe and the confluence to rotate, further improving the heat dissipation effect of the spiral heat dissipation pipe. At the same time, the high-pressure spray water impacts the support block and the breaking nails on the top of the spiral plate. The high-pressure spray water can be dispersed by the breaking nails, and the interior of the cooling box can be quickly cooled, further improving the heat dissipation effect of the spiral heat dissipation pipe.

The distillation heater 102 can improve the distillation effect of crude fatty acids. The guide cone block 107 can be taken out from the bottom of the steam guide hood 105 by the rotating plate 109 at the bottom of the guide cone block 107, so as to clean the impurities on the surface of the guide cone block 107, thereby improving the impurity distillation effect.

[0034] Secondly, by setting up the mixing box 114, not only can the mixing motor 117 be used to drive the mixing main gear 118 to rotate, but also the meshing connection between the mixing main gear 118, the mixing slave gear 119 and the meshing gear ring 120 can realize the self-rotation of the mixing slave gear 119. Since the meshing gear ring 120 is fixedly installed inside the mixing box 114, the revolution of the meshing gear ring 120 can be realized. The mixing main gear 118 drives the supporting tripod 121 and the first mixing auger 122 to rotate, and at the same time, the meshing gear ring 120 drives the second spiral cleaning blade 124 to rotate and revolve at the same time, thereby improving the mixing degree of the crude fatty acids and facilitating the separation and purification of the crude fatty acids.

[0035] Finally, the steam generated by distillation is introduced into the diverter 205 by using the air inlet pipe 203 and the diverter 204, and the spiral heat dissipation pipe 206 can not only realize the condensation of the steam, but also utilize the spiral structure of the spiral heat dissipation pipe 206 to make the steam flow and drive the spiral heat dissipation pipe 206 to rotate, so as to facilitate the heat dissipation of the spiral heat dissipation pipe 206. At the same time, cold water is pumped into the inside of the atomizer 214 and the spray ring 216 through the water inlet pipe 215, and the spiral heat dissipation pipe 206 is cooled by continuously generating high-pressure spray water and water mist, thereby improving the heat dissipation efficiency. The effect of high steam condensation is achieved by high-pressure spray water impacting the spiral plate 211, which makes the high-pressure spray water generate a certain spiral force, thereby driving the diverter 204, the diverter pipe 205, the spiral heat pipe 206, the confluence pipe 207 and the confluence pipe 208 to rotate, further improving the heat dissipation effect of the spiral heat pipe 206. At the same time, the high-pressure spray water impacts the support block 212 and the breaking pins 213 on the top of the spiral plate 211. The breaking pins 213 can disperse the high-pressure spray water, quickly cool down the interior of the cooling box 201, and further improve the heat dissipation effect of the spiral heat pipe 206.

A method for a continuous separation and purification device for crude fatty acids, using the continuous separation and purification device for crude fatty acids as claimed in claim 9, characterized in that: The steps are as follows: Step 1: injecting crude fatty acids into the mixing box (114) through the feed pipe (116), and driving the mixing main gear (118) to rotate through the mixing motor (117). By utilizing the meshing connection between the mixing main gear (118), the mixing slave gear (119) and the meshing gear ring (120), the mixing slave gear (119) can rotate on its own and the meshing gear ring (120) can revolve around the sun. The mixing main gear (118) drives the supporting tripod (121) and the first mixing auger (122) to rotate, and at the same time, the meshing gear ring (120) drives the second spiral cleaning blade (124) to rotate on its own and revolve around the sun, thereby fully mixing the crude fatty acids. Step 2: The mixed crude fatty acid enters the distillation box (101), and the crude fatty acid solution is initially filtered by the filter screen (127).

The impurities are heated and distilled by the heating plate (108) on the top of the guide cone block (107). The steam can be guided by arranging the steam guide cover (105) and the guide groove (106). The filtered crude fatty acid solution is stirred by rotating the stirring bracket (113) at the bottom of the connecting rod (110). The guide cone block (107) can be taken out from the bottom of the steam guide cover (105) by the rotating plate (109) at the bottom of the guide cone block (107); Step 3: The steam generated by distillation is introduced into the diverter (205) through the air inlet pipe (203) and the diverter (204) and diverted to the diverter pipe (205). The steam is condensed through the spiral heat dissipation pipe (206). The spiral heat dissipation pipe (206) is used to make the steam flow and drive the spiral heat dissipation pipe (206) to rotate, so as to dissipate heat of the spiral heat dissipation pipe (206). At the same time, cold water is pumped into the inside of the atomizer (214) and the spray ring (216) through the water inlet pipe (215). The high-pressure spray water impacts the steam. The spiral plate (211) causes the high-pressure spray water to generate a certain spiral force, thereby driving the diverter (204), the diverter pipe (205), the spiral heat dissipation pipe (206), the converging pipe (207) and the converging pipe (208) to rotate, thereby dissipating the heat of the spiral heat dissipation pipe (206). At the same time, the high-pressure spray water impacts the support block (212) and the scattering pins (213) at the top of the spiral plate (211), and the high-pressure spray water can be dispersed through the scattering pins (213), thereby quickly cooling the interior of the cooling box (201).
