Problems solved by technology

[0003] Due to the volume limitation of the dust collector, the gas ash in the dust collector needs to be discharged every day to meet the production requirements. When the gas ash in the dust collector is unloaded, the inside of the tank is under pressure. Most ironmaking plants use agitating cage humidifiers to The dust collector performs ash unloading operation, which inevitably causes gas ash to raise dust during operation, and there is a risk of gas leakage

Abstract

The invention relates to the technical field of blast furnace ash conveying, and provides a blast furnace gas ash safe conveying system which is arranged on one side of a dust remover and comprises a gas pump, a stock bin and an external control cabinet, an inlet of the gas pump is communicated with a discharging pipe of the dust remover through a first pipeline, and a first control valve is installed on the first pipeline; the interior of the stock bin is communicated with an outlet of the gas pump through a second pipeline, a pressure detector is installed on the upper portion of the inner wall of the stock bin, and the external control cabinet is electrically connected with the gas pump, the first control valve and the pressure detector. According to the safe conveying system for the blast furnace gas dust, gas dust raising cannot be caused when the gas dust is discharged, and the risk of gas leakage does not exist.

Description

technical field [0001] The invention relates to the technical field of blast furnace ash transportation, in particular to a blast furnace gas ash safety transportation system. Background technique [0002] The crude gas produced in the blast furnace smelting is discharged through the downcomer. In order to separate the gas ash in the crude gas, a dust collector is generally installed at the outlet of the downcomer. The dust collector is usually a gravity dust collector or a cyclone dust collector. When the crude gas passes through the dust collector, the gas ash in the crude gas is separated from the gas by its own weight or centrifugal force. The gas ash is discharged through the ash discharge pipe at the lower part of the dust collector, and the separated primary purified gas is discharged through the outlet pipe of the dust collector and enters the The next process continues to dust removal. [0003] Due to the volume limitation of the dust collector, the gas ash in the...
