Distillation tower

Abstract

The invention discloses a distillation tower. The distillation tower comprises a flow dividing part located at the upper part and a stirring part located at the lower part, wherein a plurality of flowdividing pipes are vertically arranged in the flow dividing part; a connecting pipe is arranged in the stirring part; the upper end of the connecting pipe is connected with the lower end of the flowdividing part and the lower end of the connecting pipe is lower than a waste gas discharging opening formed in a side wall of the stirring part; the distillation tower is provided with various gas-carrying connectors, a material circulating pipe and a flow dividing pipe, so that mixed gas mixed in emulsion is subjected to flow division in the flow dividing pipe and is circulated between the distillation tower and a circulating pipeline; VOC (Volatile Organic Compounds) in the emulsion can be efficiently separated, the content of the VOC in the emulsion is greatly reduced and the quality of theemulsion is improved; the distillation tower disclosed by the invention is simple in structure and low in operation cost.

Description

technical field [0001] The invention relates to the technical field of separation and purification devices for paint, in particular to a distillation tower. Background technique [0002] As there are more and more types of emulsion products, their applications are becoming more and more extensive, but the emulsion products on the market generally contain more volatile organic compounds (VOC), which do not meet the requirements of environmental protection and are not conducive to human health; The existing technology is not perfect for the treatment of volatile organic compounds in emulsion products. The traditional VOC detachment process is not only costly and time-consuming, but also the detachment effect is not ideal, which greatly limits the development of high-quality emulsion products. [0003] The function of the distillation tower is mainly to separate the mixed liquid, and use the principle of different liquids under different conditions, such as different temperatur...
