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, which optimizes the blowdown efficiency of the vaporization flue by modifying the layout of the blowdown pipeline and improving the way of valve blowdown. The valves are installed away from important parts of the human body, which can achieve the purpose of improving safety. The centralized layout of the valves has the advantages of facilitating the distribution of pipeline valves, and facilitating the observation and stationing of operators. After the gate valves, fast sewage valves are installed respectively. Normally open, the sewage discharge efficiency can be improved by operating the fast sewage valve. When the fast sewage valve fails or leaks, the gate valve can be closed for timely maintenance or replacement.

Description

Technical field [0001] The invention involves a construction method of a furnace vaporization flue sewage system, which is a technical field of metallurgical industry production. Background technique [0002] As a very important part of the turning furnace vaporization flue, the residual heat boiler system of the turntable furnace is a very important part. In order to prevent the furnace water from being excessively concentrated due to evaporation and ensure the normal indicators of the boiler water, the daily pollution of the system cannot be ignored.The sewage of the vaporization cooling flue is mainly to use the sewage pipe of the flue to reduce the impurities in the flue through sewage, reduce the failure rate of the flue, and extend the service life. [0003] In the existing technology, although the periodic sewage cycle and sewage volume are continuously explored, due to the fixed section, mobile section, middle first section, middle two section, middle three sections, and ...

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.
