Problems solved by technology

[0003] Since the process gas enters the central gas collecting pipe and exits the shift furnace after only one catalytic reaction, part of the process gas reacts insufficiently, resulting in a relatively high exhaust gas component in the product gas, which affects the quality index of the product gas

Abstract

The invention relates to a central gas collecting pipe of a shift converter. The central gas collecting pipe comprises a pipe body, wherein gas inlet holes are fully distributed in the pipe body; thelower end of the pipe body is connected with an expansion pipe with a diameter larger than the diameter of the pipe body; the lower end of the expansion pipe is connected with a gas distributing pipe;the lower end of the gas distributing pipe is sealed by a bottom plate; and a large number of gas outlet holes are evenly distributed in the wall of the gas distributing pipe. The central gas collecting pipe can guide finished gas to enter a catalyst layer again for a secondary reaction so as to improve the quality of the finished gas.

Description

Technical field: [0001] The invention belongs to the technical field of converter furnaces, and in particular relates to a central gas collecting pipe of a converter furnace. Background technique: [0002] The shift furnace can introduce the process gas into the catalyst for chemical reaction, and then generate the product gas, and the central gas collecting pipe is a device for collecting the product gas. The central gas collecting pipe is installed inside the converter shell, and the outside of the central gas collecting pipe is the catalyst. , the interior is hollow and communicates with the product gas outlet provided on the shell of the shift furnace. The process gas passes through the catalyst layer and enters the central gas collecting pipe, and then exits the shift furnace. [0003] Since the process gas enters the central gas collecting pipe and exits the shift furnace after only one catalytic reaction, part of the process gas reacts insufficiently, resulting in hig...
