Embodiment Construction
[0014] In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0015] like figure 1 As shown, the novel deodorizing tower of the present invention includes a packed tower 1 located at the upper part and a tray tower 5 located at the lower part. The upper end of the packed tower 1 is provided with an oil inlet 2 of the packed tower, so that the grease flows into the tower through it. Between the packed tower 1 and the plate tower 5, there is a packed tower stay section 3 equal to the inner diameter of the plate tower, and a packed tower stay section oil discharge port 4 is arranged at the lower part of the side wall of the packed tower stay section 3, and the plate tower 5 passes through. The 4 trays are equally divided into 4 layers from top to bottom, and each layer is provided with a tray tower stea...

The invention discloses a novel oil deodorization tower capable of treating various raw materials. The novel oil deodorization tower comprises a packed tower and a plate tower located at the lower part of the packed tower, wherein the plate tower is at least provided with two tower layers from top to bottom. The novel oil deodorization tower is characterized in that a packed tower staying segment is arranged between the packed tower and the plate tower; the lower part of the side wall of the packed tower staying segment is provided with a staying segment oil drain outlet; the upper part of the side wall of a first tower layer of the plate tower is provided with a plate tower oil inlet; and an oil outlet at the bottom of the plate tower is provided with an oil pump and is connected with an oil inlet of the packed tower through an oil delivery pipe. The deodorization tower can be used for deodorizing various raw oils and particularly solving the problem of high acid value caused by hydrolysis in the process of deodorizing oils such as corn oil, sunflower seed oil and the like with high unsaturated fatty acid content.
Description
technical field [0001] The invention relates to the field of oil and fat industry, in particular to a novel oil and fat deodorization tower capable of processing various raw materials. Background technique [0002] In the oil refining production, deodorization is a very important process. The principle is to use high temperature and high vacuum distillation technology to remove some odorous aldehydes and ketones in the oil. Deodorization tower is the core equipment of this process. Common deodorization towers include packing type deodorization tower and plate type deodorization tower. [0003] The physical deacidification effect of the packed deodorization tower is good, but the deodorization effect is not as good as that of the plate deodorization tower. The plate deodorization and decolorization effect is good, the structure is simple, and the failure rate is low. [0004] In recent years, technicians have combined packed deodorization towers and plate deodorization tower...
