DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0022] Please refer to Figures 1-4The figure shows a preferred embodiment of this utility model: an organic heat carrier furnace for palm oil fatty acid production, comprising a furnace body 1, a furnace cover 2 on the top of the furnace body 1, the two ends of the furnace cover 2 being secured to the top of the furnace body 1 by spring pins, a heating chamber 3 on the inner side of the furnace body 1, a reactor 4 inside the heating chamber 3, a chamber cover 5 adapted to the heating chamber 3 at the bottom of the furnace cover 2, and a circulating pipe 7 connecting the heating chamber 3 and the chamber cover 5, the circulating pipe 7 being distributed in the heating chamber.

[0023] Understandably, when the furnace cover 2 is on the furnace body 1, the heating chamber 3 and the cover 5 can be in complete contact. After the electromagnet 8 is activated, it can pull the movable plug 9 slightly away from the heating chamber 3 and the cover 5, thus unblocking the circulation pipe 7. At this time, the organic heat carrier (usually special heat transfer oil) can flow in the circulation pipe 7. It should be noted that the magnetic poles of the electromagnet 8 can be controlled by changing the direction of the current. Before the furnace cover 2 is removed, the movable plug 9 can be reset, keeping the circulation pipe 7 in the heating chamber 3 and the cover 5 closed. It should be added that the heating chamber 3 and the oil tank 6 are equipped with limiting grooves for the movable plug 9, so there is no need to worry about the movable plug 9 slipping off due to excessive sliding (see reference). Figure 3 ).
[0024] The circulation pipeline 7 further includes an oil inlet pipe 10 and an oil outlet pipe 11. The oil inlet pipe 10 connects to the heating chamber 3 at the bottom center of the heating chamber 3, and one end of the oil outlet pipe 11 connects to the lower side of the chamber cover 5. Figure 3 As shown, the organic heat carrier flows in from the bottom of heating chamber 3, swirls, and then... Figure 3 Starting from the bottom left side of the heating chamber 3, the flow spirals upwards and finally flows into the chamber cover 5 from the top of the heating chamber 3. Then, it flows from the outside to the inside of the chamber cover 5 in a spiral manner, and finally rises from the center of the chamber cover 5 and flows back into the oil tank 6 along the oil outlet pipe 11. During the process, the flow path of the organic heat carrier can cover the surface of the reactor 4, which improves the uniform heating and rapid heating and cooling of the reaction mixture.

[0027] In order to facilitate the cleaning of the afterburning cinder, one end of the combustion chamber 14 is provided with an access hole 16, one end of the access hole 16 is threadedly connected with a plug, after the plug is opened, the cinder accumulated inside the furnace can be sucked out by the industrial dust collector.
[0028] In order to facilitate lifting, the lower end of the two sides of the furnace cover 2 is provided with a supporting table, the outer wall close to the upper side of the furnace body 1 is provided with a groove with a size suitable for the inner side of the supporting table, which facilitates the furnace cover 2 to fall along the fixed track, the spring pin is arranged in the groove, the inner side of the supporting table is provided with a groove communicated with the spring pin and with a size suitable for the movable end of the spring pin, which facilitates the movable end of the spring pin to pass through, which can be referred to in the lower side of the furnace cover 2. Figure 1
[0029] Wherein, the outer wall of the furnace body 1 is fixedly installed with an oil changer 17 at one end, one end of the oil changer 17 is communicated with the oil tank 6 through a pipeline, one end of the pipeline is fixedly installed with a solenoid valve, which facilitates the organic heat carrier in the oil tank 6 to be replaced in time after reaching the service life.
[0030] Regarding the specific use of the furnace body 1 in palm oil fatty acid production, first, the reaction mixture is loaded in the reactor 4, after the furnace cover 2 is opened, the reactor 4 can be put into the inner side of the heating bin 3, then the furnace cover 2 can be closed to start heating the reaction mixture;
[0031] When heating, the biomass fuel is poured into the material conveying channel 12 and falls into the combustion chamber 14, in the process, the rotating combustion chamber 14 can also be pushed to make the fuel more evenly distributed, after reaching the required heating temperature, the organic heat carrier, i.e. the heat conducting oil, can be forced to circulate from the oil tank 6 along the circulating pipeline 7 driven by the oil pump, this circulation process ensures that the heat carrier continuously obtains heat from the heating furnace, transfers heat to the heating bin 3 and the bin cover 5, and finally transfers heat to the reactor 4 from the heating bin 3 and the bin cover 5, ensuring stable heat supply.
[0032] It should be noted that the furnace body 1 uses fuel in the embodiment, taking biomass fuel as an example, but the fuel of the furnace body 1 can also be oil or coal, and in the heating process, the temperature in the furnace is controlled by the installed safety devices such as temperature and pressure measuring equipment not shown in the figure to monitor the operation, to ensure safe and stable operation.
