Construction method for blowdown system of converter vaporization flue

Abstract

The invention discloses a construction method for a blowdown system of a converter vaporization flue. Blowdown efficiency of the vaporization flue is optimized by changing blowdown pipe layout and improving a valve blowdown manner. Valves are mounted to shun important parts of a human body, so the purpose of security improvement is achieved; concentrated layout of the valves facilitates distribution of pipeline valves and observation and standing of operation personnel; quick blowdown valves are respectively and additionally arranged after arrangement of a gate valve, and the gate valve is normally open at ordinary times; blowdown efficiency is improved through operation of the quick blowdown valves; and when the quick blowdown valves have fault or leakage, the gate valve can be closed for timely maintenance or replacing.

Description

technical field [0001] The invention relates to a construction method of a converter vaporization flue blowdown system, belonging to the technical field of metallurgical industrial production. Background technique [0002] The converter vaporization flue is a very important part of the converter waste heat boiler system. In order to prevent excessive concentration of boiler water due to evaporation and ensure the normal indicators of boiler water, the daily blowdown of the system cannot be ignored. The blowdown of the vaporization cooling flue is mainly to use the blowdown pipe at the lower end of the flue to reduce the impurities in the flue through blowdown, reduce the failure rate of the flue, and prolong the service life. [0003] In the prior art, although the regular blowdown period and the blowdown amount have been summed up through continuous exploration, the fixed section, the moving section, the middle section, the middle section 2, the middle section 3 and the end...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, although the regular blowdown period and the blowdown amount have been summed up through continuous exploration, the fixed section, the moving section, the middle section, the middle section 2, the middle section 3 and the end section of the vaporization flue are three-dimensional longitudinally along the converter building. The distribution across each floor, and the distribution of equipment and pipelines on each floor of the converter plant is dense, and the valves originally designed for each sewage discharge point are installed in each section nearby, which causes a lot of inconvenience to the sewage discharge and reduces the efficiency of the vaporization flue sewage discharge. and inconvenient to maintain

In addition, slipping, bruising and scalding of operators due to sewage discharge occurred from time to time, which caused certain safety hazards and also hindered workers' enthusiasm for work.
