Drain water seal for primary dust removal system of converter

Abstract

The invention discloses a drainage water seal for a primary dedusting system of a converter, relates to the field of metal smelting, and includes a water-sealed box body, an airtight cover plate, an upper exhaust pipe, a partition plate, a deflector plate and a movable cover plate, and a water-sealed box body The top side of the cover is provided with a movable cover and a closed cover. The closed cover is connected to the upper exhaust pipe. Deflector; the side of the water-sealed box close to the airtight cover is provided with the first opening connected to the horizontal part of the sewage inlet pipe, and the bottom of the water-sealed box on the bottom side of the airtight cover is opened with the first opening for sewage discharge Two openings, an outlet is provided on the side of the water-sealed box close to the movable cover; sewage from the first opening flows out through the water-sealed box. The invention has smooth sewage discharge, is not easy to accumulate mud, is flexible in layout, convenient in maintenance, safe and reliable, and carbon monoxide at the water seal can be effectively recovered or discharged.

Description

technical field [0001] The invention relates to the field of metal smelting, in particular to a drainage water seal for a primary dust removal system of a converter. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Converter smelting is a reaction process of oxygen blowing and decarburization at high temperature. In this process, a large amount of carbon monoxide and high-temperature gas containing iron dust will be produced. If it is discharged without proper treatment, it will definitely cause great environmental pollution and It is a great waste of energy, so it is necessary to set up a dust removal system. [0004] At present, the most commonly used dedusting systems for converter primary dedusting systems include wet, semi-dry and LT dry systems. Among them, converter primary wet and semi-dry dedusting systems need to spray a large amount of f...

Problems solved by technology

[0005] Aiming at the disadvantages in the prior art that the drainage water seal is easy to accumulate mud and block the sewage discharge, frequent cleaning and maintenance, the position of the drainage water seal must be consistent with the center of the purification equipment, it is difficult to arrange, and the carbon monoxide content in the drainage water seal exceeds the standard, which has certain safety hazards. The purpose of the invention is to provide a drainage water seal for the primary dust removal system of the converter, which has smooth sewage discharge, is not easy to accumulate mud, flexible layout, convenient maintenance, safety and reliability, and carbon monoxide at the water seal can be effectively recovered or discharged
