Isothermal and uniform flowing-velocity double water-cooled horizontal reactor

Abstract

The invention discloses an isothermal and uniform flowing-velocity double water-cooled horizontal reactor, which comprises a cylinder body, a left seal head and a right seal head, a left-end outer tube plate and a right-end outer tube plate respectively arranged at left and right ends of the cylinder body, a left-end inner tube plate and a right-end inner tube plate arranged in the cylinder body,a catalyst frame arranged between the left-end inner tube plate and the right-end inner tube plate, and a sleeve type water-cooled heat exchange tube group. The sleeve type water-cooled heat exchangertube group comprises two adjacent sleeve layers with opposite water inlet directions, and each sleeve layer comprises a plurality of sleeves, wherein the sleeve comprises an inner sleeve and an outersleeve; one end of the outer sleeve is fixed by an inner tube plate, and the other end is sealed and horizontally protrudes into the catalyst bed; one end of the inner sleeve is fixed by the outer tube plate, and the other end horizontally protrudes into the corresponding outer sleeve. The catalyst of the invention forms a rectangular catalyst bed outside the tube, and the reaction gas passes through the bed from top to bottom without axial flow; the sleeve water-cooled heat exchanger tube groups are symmetrically arranged across the catalyst bed to achieve the isotherm of the catalyst bed and realize the isotherm reaction of the bed.

Description

technical field [0001] The invention belongs to the field of gas-solid phase catalytic reactors in chemical reaction engineering, and relates to a low-pressure reaction device, in particular to a double-water-cooled horizontal reactor with isothermal and constant flow rates, in particular to a kind of reactor with strong heat transfer capability, low fluid resistance and Double water-cooled horizontal reactor with good isothermal performance. Background technique [0002] There are many types of internally cooled gas-solid reactors, among which shell-and-tube reactors are relatively common internally cooled gas-solid reactors. Shell-and-tube reactors can be divided into axial flow reactors and radial flow reactors according to the flow direction of the reaction gas through the catalyst bed, and axial flow reactors can be divided into vertical axial flow tube shells according to the catalyst loading method. reactor and vertical axially cooled tube reactor.

Problems solved by technology

The disadvantage is that there is a complex flow state where radial flow and axial flow coexist at the upper and lower ends of the bed. In this complex flow state area, it is not suitable for reactions that require high isothermal and constant flow rates.
