The deacidification and deodorization tower is a new type of oil deacidification and deodorization equipment. It combines the packed tower and the plate tower, which not only maintains the physical deacidification effect of the packed tower, but also has high-efficiency deodorization functions. Used separately, it is especially suitable for oil refineries with frequent variety changes and processing oil products with complex sources, poor quality and deep color, such as rice bran oil, tea seed oil, industrial hog oil, etc. The main features of the deacidification and deodorization tower are compact structure, small footprint, convenient use, small steam consumption, good color of finished oil, good deacidification effect and low refining consumption. Flexible operation, low use and maintenance costs. The upper part of the deacidification and deodorization tower is a packing section, and the lower part is a plate section.

   The oil enters from the top of the deacidification and deodorization tower, and is evenly distributed on the packing through the oil separator to form an oil film, which flows from top to bottom, and contacts with the countercurrent stripping superheated steam on the packing in reverse direction, and first distills fatty acids and Part of the odor component is sucked away by vacuum, and the oil flows into the plate section through the pipeline. The direct steam in the plate section sprays out from the oil in the form of bubbling, and contacts with the oil again for stripping. The oil in the plate section reduces the boiling point of the odorous substances through high vacuum, and through the distillation of superheated steam, so as to achieve For the purpose of deodorization, the deodorized oil is discharged from the deodorization tower from the bottom of the tower.

   The deacidification and deodorization tower is composed of packing section and plate section, and the packing section and plate section can be used separately. The upper part of the packing section is an oil inlet and an oil separator. The decolorized oil enters the packing section from the oil inlet and is evenly distributed on the packing through the oil separator. The packing section is filled with structural packing. The plate section is connected with the packing section through the flange. Each tray tower is divided into 4 grids, the upper tray is provided with direct steam inlet, and the upper tray of the lower tray is provided with steam nozzles (alternately arranged layer by layer), steam is sprayed into the oil through the nozzles on the tray in the form of bubbling Under the action of the small spray barrel, the oil forms an oil circulation in each tag. The oil in the upper layer starts from the first grid in a clockwise direction to the fourth grid of this layer, and then enters the first grid of the lower layer through the oil guide pipe until the bottom layer. In order to facilitate observation and maintenance, there are sight glasses and maintenance manholes on the plate section.
