Problems solved by technology

[0002] Most of the existing small fractionation devices are made by shrinking the existing large fractionation towers, which leads to the inability to set more trays in the existing small fractionation devices, and the limitation of the number of trays will lead to poor fractionation effect. Secondly, The existing plant has a fixed number of trays and is difficult to adjust

Abstract

A purification and fractionation device for naphtha processing belongs to the field of fractionation equipment. The device comprises a tank body. Supporting legs are fixedly mounted on the bottom surface of the outer wall of the tank body. A reboiler is arranged at the bottom of one side of the tank body. A cooler is arranged at the top of the tank body. A feeding pipe is fixedly mounted on one side of the tank body, and a vertical circular pipe is arranged in the tank body. The circular pipe penetrates through the top surface and the bottom surface of the tank body and is fixedly connected with the tank body. A spiral blade is fixedly mounted between the periphery of the circular pipe and the tank body, a plurality of partition plate groups which are uniformly distributed are fixedly mounted on the spiral blade, and each partition plate group consists of two vertical partition plates. When the vertical part of an L-shaped pipe is in a horizontal state, all components of a corresponding fractionation compartment can flow into an adjacent lower fractionation compartment, the two fractionation compartments are communicated, it can be understood that the two fractionation compartments can be regarded as one fractionation compartment, and then a user can adjust the number of the fractionation compartments.

Description

technical field [0001] The invention belongs to the field of fractionation equipment, in particular to a purification and fractionation device for naphtha processing. Background technique [0002] Most of the existing small fractionation devices are made by shrinking the existing large fractionation towers, which leads to the inability to install more trays in the existing small fractionation devices, and the limitation of the number of trays will lead to poor fractionation effect. Secondly, The number of trays in the existing device is fixed and difficult to adjust. Contents of the invention [0003] The invention provides a purification and fractionation device for naphtha processing to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A purification and fractionation device for naphtha processing, comprising a tank body, support legs are fixedly installed on the bottom surface of the oute...
