Embodiment Construction

[0019] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, through the description of the embodiments, to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solutions of the present invention.

[0020] The structure of the present invention as shown in the figure is a single blast furnace without a gas cabinet to produce a gas pipe network, and the blast furnace is an iron-making blast furnace; the gas pipe network is also connected to a gas user.

[0021] In order to solve the problems existing in the prior art and overcome its defects, and realize the invention purpose of guaranteeing the safety of the gas pipeline network of the gas cabinet, the technical scheme adopted in the present invention is:

[0022] like figure 1 As shown, the gas pipeline network of the single blast furnace with gasless cabinet of the pr...

Abstract

The invention discloses a gas-holder-free single blast furnace produced gas pipe network. The above blast furnace is an iron making blast furnace; and the gas pipe network is connected with a gas use unit, and is also connected with a low-pressure nitrogen pipe network through a nitrogen pipeline. By adopting the above technical scheme, a burner valve can be turned off under the decompression of the pipe network of each of gas users, so the positive pressure of the pipe network is guaranteed, a back draft accident is prevented, and the safety and the stability of the running of the pipe network are guaranteed; and after the blast furnace reblowing, the pressure in the pipeline is always positive, no air enters, and the explosion-proof test of blast furnace gas users within a short time is qualified, so the rapid production recovery of the users is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of production equipment in metallurgical industry, and relates to the technology of blast furnace production equipment, more particularly, the invention relates to a gas pipe network for producing gas in a single blast furnace without a gas cabinet. Background technique [0002] Since the blast furnace is in the initial stage of production, the production is still unstable, and there are often planned and unplanned emergency gas cuts. Plans to cut off the gas and the fan suddenly trips, causing the blast furnace to cut off the gas from time to time; [0003] In addition, due to the production of a single blast furnace, once the blast furnace is cut off, the pressure of the pipe network will drop sharply, which may cause negative pressure in the pipe network. [0004] In order to solve the above problems, most iron and steel enterprises now use gas cabinets to protect the pipeline network in the case of sing...
