[0021] 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:

[0022] Example:

[0023] This embodiment introduces a specific structure of a heat recovery and utilization device in edible oil production. Figure 1-Figure 4 As shown, it includes a heat exchange system and a heat energy capture tower 16 connected to the inside of the heat exchange system, the heat energy capture tower 16 includes a base 11, a water distribution plate 5 is arranged inside the base 11, a circulating water outlet 4 and an air inlet 1 are processed on the outer wall of the base 11, a reinforcing rib 2 is arranged on the top of the base 11, a packing frame 7 is assembled and connected to the top of the reinforcing rib 2, an injection frame 9 is arranged on the top of the packing frame 7, a circulating water inlet 8 is processed on the outer wall of the injection frame 9, a plurality of spiral nozzles 6 are processed inside the injection frame 9, the top of the injection frame 9 is covered with a top cover 10, and an air outlet 3 is processed on the outer wall of the top cover 10;

[0024] Among them, the packing frame 7 performs the packing function, and the base 11 located at the bottom of the reinforcing rib 2 performs the defoaming function. The hot air enters from the bottom of the heat energy capture tower 16 and mixes with the circulating water that flows back to the packing frame 7 through the circulating water pump 13, so that the gas and liquid are in reverse contact. At this time, the gas is vacuumed away, and the water increases the contact area with the gas under the action of the packing, and increases the residence time in the air, so as to achieve the purpose of absorbing heat;

[0025] Secondly, the heat energy capture tower 16 has a diameter of 2.6m and a height of 6.98m. The packing frame 7 thereon is equipped with a structural packing ball ring. By using the injection-molded ball ring with evenly distributed small holes, the vapor-liquid dispersion can be controlled to avoid the channel flow short-circuiting phenomenon;

[0026] At the same time, in order to facilitate observation and cleaning of the filler, the top of the top cover 10 is set as a sight glass. When the gas to be absorbed enters the interior of the base 11 through the air inlet 1, it contacts with the misty hot water, and the heat is instantly absorbed. The hot water that absorbs the heat is returned to the heat energy capture tower 16 after the circulating water pump 13 converts the heat to the workshop process needs, and then passes through the spiral nozzle 6 to form a mist, which is evenly distributed on the filler inside the filler frame 7; Figure 4 As shown, the heat exchange system includes two shakers 14, one side of the top of the two shakers 14 is connected to a cold drying box through a pipeline, the bottom of the two shakers 14 is connected to a blower 17 through a pipeline, and the top of the two shakers 14 is connected to a blower 15 through a pipeline;

[0027] There are two air inlets 1, which are symmetrically arranged on both sides of the base 11, and the circulating water outlet 4 is arranged on the front of the base 11. After the heat energy capture tower 16 is supported and applied to the heat exchange system, one end of the two fans 15 is connected to the air inlet 1 through a pipeline;

[0028] At the same time, two air outlets 3 are provided, and they are respectively oriented in the same direction as the two air inlets 1, the circulating water inlet 8 is oriented in the same direction as the circulating water outlet 4, one end of the circulating water inlet 8 is connected to a circulating water pump 13 through a pipeline, one end of the circulating water pump 13 is connected to a plate heat exchanger 12, two plate heat exchangers 12 are provided, one end of one plate heat exchanger 12 is connected between the other plate heat exchanger 12 and the circulating water outlet 4, the two plate heat exchangers 12 are commonly connected to a hot air heater and a de-heating air heater, and the circulating water pump 13 is also arranged between the hot air heater and the two plate heat exchangers 12;

[0029] Secondly, the hot air (85°C) is affected by the operation of the fan 15 on the top of the shaker 14. After entering the shaker 14, the soybean meal powder in the hot air is removed, and then it is discharged from the inside of the fan 15 and finally enters the heat energy capture tower 16. After entering the heat energy capture tower 16, the wind is absorbed by the self-circulating water and then discharged into the atmosphere. The circulating water that absorbs the heat brings the heat to the production process of the workshop.

[0030] By adopting the above technical solution:

[0031] The above design applies the heat energy capture tower 16 to the heat exchange system, so that the hot air passes through the Shakron 14 to remove the soybean meal powder in the hot air, and then enters the heat energy capture tower 16 to be absorbed by the self-circulating water, and then discharged to the atmosphere through the air outlet 3 on the top cover 10. The circulating water that absorbs the heat brings the heat to the production process of the workshop for production use. This process only needs to be continued, and the heat can be repeatedly recycled.

[0032] When the heat capture tower 16 cooperates with the circulating water pump 13 and the two plate heat exchangers 12 to perform heat exchange, the gas to be absorbed enters the tower body and contacts the mist hot water inside the heat capture tower 16, so that the heat is absorbed instantly. The hot water that absorbs the heat passes through the plate heat exchanger 12 to convert the heat to the workshop process needs and then returns to the tower. After passing through the spiral nozzle, it forms mist and is evenly distributed on the filler for preheating.

[0033] 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.
