Disclosure of Invention

The invention aims to provide a deodorizing tower for vegetable oil production, which aims to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme:

a deodorizing tower for vegetable oil production comprises a steam extraction tower and a trapping tower. The bottom of the steam extraction tower is provided with a support, the collecting tower is communicated with the upper end of the steam extraction tower, the top of the collecting tower is communicated with an exhaust pipe, and the exhaust pipe is communicated with a vacuumizing device, so that the steam extraction tower and the inside of the collecting tower are in a vacuum state, and fatty acid and odor substances are convenient to evaporate. The upper end intercommunication of steam extraction tower has the medicament entry, and the medicament entry intercommunication has the nozzle, and inside the medicament got into and spout into the entrapment tower from the medicament entry in the nozzle, the below of nozzle was fixed in entrapment tower inside and is provided with through the board, and fatty acid and stink material evaporation can pass through the board, and fatty acid and stink material pass through the board top and mix with nozzle spun medicament to the condensation. The corresponding position of the penetrating plate is fixedly provided with a collecting cavity on the outer side wall of the collecting tower, a fatty acid outlet is formed in the collecting cavity, and a valve is arranged on the fatty acid outlet. The inner side wall of the trapping tower is provided with a plurality of through holes, so that the trapping tower is communicated with the collecting cavity. Fatty acid and odor substance flow into the collecting cavity through the through holes, and the fatty acid and odor substance can be discharged by opening the fatty acid outlet.

The inside of steam extraction tower is provided with the coiled pipe, and the upper end intercommunication of coiled pipe has steam outlet, and the lower extreme intercommunication has steam inlet, and inside steam entered into the coiled pipe from steam inlet, vegetable oil entered into the entrapment tower from the vegetable oil entry inside, is heated on the coiled pipe to because fatty acid and stink material boiling point are lower, thereby inside the evaporation entering entrapment tower. The serpentine pipe is provided with a plurality of heat conduction fins, and the arrangement of the heat conduction fins increases the heat transfer area of the serpentine pipe and improves the heat transfer rate. The bottom of the steam extraction tower is communicated with an oil outlet, and the separated vegetable oil is discharged from the oil outlet.

As a further scheme of the invention: the penetrating plate is of a plate-shaped structure with a convex middle part, so that the fatty acid and the odor substance can flow to the periphery conveniently.

As a further scheme of the invention: the collection cavity is obliquely arranged, and the fatty acid outlet is communicated with the bottom of the collection cavity, so that the fatty acid and the odor substances can be conveniently discharged.

As a further scheme of the invention: the bottom of the steam extraction tower is provided with a cooling plate, and the cooling plate is convenient for cooling the vegetable oil. The bottom of the steam extraction tower below the cooling plate is communicated with a condensed water inlet and a condensed water outlet, and condensed water is introduced into the bottom of the steam extraction tower, so that the cooling of the vegetable oil is accelerated.

As a further scheme of the invention: the interior bottom of steam extraction tower is provided with the condenser pipe, and the both ends intercommunication comdenstion water import and the comdenstion water export of condenser pipe, the setting up of condenser pipe makes the better cooling of vegetable oil.

As a further scheme of the invention: the condenser pipe is formed by communicating a plurality of groups of scroll pipes, the lower end of the condenser pipe is communicated with the oil outlet, and the upper end of the condenser pipe is communicated with the condensed water outlet, so that gradient cooling can be formed, and cooling is more sufficient.

Compared with the prior art, the invention has the beneficial effects that: the vegetable oil enters the inside of the collecting tower from the vegetable oil inlet, is heated on the coiled pipe, and is evaporated into the inside of the collecting tower due to the lower boiling point of the fatty acid and the odor substance. The serpentine pipe is provided with a plurality of heat conduction fins, and the arrangement of the heat conduction fins increases the heat transfer area of the serpentine pipe and improves the heat transfer rate. The heat conduction fins are distributed in a staggered and inclined mode, so that the flow rate of the vegetable oil is reduced, and the heat transfer path is enlarged.
