Heat transfer system of shift converter

Abstract

The invention relates to a heat transfer system of a shift converter. The heat transfer system comprises a plurality of heat exchange tubes arranged between an outer distributor and a central gas collecting tube, wherein the plurality of heat exchange tubes are concentrically arranged by taking the central gas collecting tube as the center, so a plurality of heat exchange tube rings are formed; aplurality of positioning rings which are arranged along a vertical direction are arranged at the periphery of each heat exchange tube ring; the inner wall of any positioning ring is connected with a sleeve; the sleeves are arranged along the axial direction of the heat exchange tubes; each heat exchange tube is inserted into the corresponding sleeve; every two adjacent circles of positioning ringsare connected through a plurality of connecting plates so as to fix the distance between every two adjacent circles of heat exchange tubes; the upper ends of all the heat exchange tubes are gatheredto a plurality of upper collecting boxes; the lower ends of all the heat exchange tubes are gathered to a plurality of lower collecting boxes; each upper collecting box is provided with a first connector; and each lower collecting box is provided with a second connector. With the heat transfer system, the reaction temperature of the whole catalyst layer can be balanced, the working efficiency of the shift converter is improved, and the quality of product gas is improved.

Description

Technical field: [0001] The invention belongs to the technical field of converter furnaces, and in particular relates to a heat transfer system for a converter furnace. Background technique: [0002] The converter furnace is composed of an outer casing, an outer distributor located inside the outer casing, and a central gas collecting pipe located inside the outer distributor. The process gas buffer chamber is formed between the outer casing and the outer distributor, and the outer distributor and the central gas collecting pipe are formed. In the catalytic chamber, the outer casing is provided with an air inlet connected to the buffer chamber, an air outlet connected to the central gas collecting pipe, and a feed port and a discharge port connected to the catalytic chamber. The catalytic chamber is filled with catalyst to form a catalyst layer. The process gas enters the buffer chamber from the inlet, diffuses to the catalyst layer through the outer distributor to catalyze ...

AI Technical Summary

Problems solved by technology

There are some problems in the actual operation of this structure. In the actual operation, it is found that due to the high furnace body of the shift furnace, after the heat exchange tubes are filled with catalyst in a fixed state without supports, the heat exchange tubes are biased in the catalyst layer, and the heat exchange tubes are distributed. Unevenness leads to uneven cooling effect of the heat transfer system on the catalyst layer, and there is a large temperature difference in each area of ​​the catalyst layer, resulting in high energy consumption of the heat transfer system, the catalytic efficiency of the converter cannot be fully utilized, and the proportion of process gas in the product gas is high , the gas quality of the product is difficult to improve
