Problems solved by technology

In addition, due to the belt aging problem of the steel wire belt of the ash conveying device, the steel wire belt must be replaced regularly, and the time for each replacement is about 15 days, which will inevitably affect the sintering output

Abstract

The invention relates to a device used for running of a one-side tower of dense-phase tower desulfuration equipment, and belongs to the technical field of dense-phase tower desulfuration equipment inthe metallurgical industry. According to the device, a desulfuration tower (6), a transition chamber (7) and an ash bucket (9) of a bag-type dust collector (8) are respectively connected with ash pipes (1), the other ends of the ash pipes (1) are connected with an inlet of a spiral conveyer (3), an outlet of the spiral conveyer (3) is connected with an inlet of a reversible spiral conveyor (4), and an outlet of the reversible spiral conveyor (4) is formed in the bottom of a bucket elevator (10). The device has the advantages that when any one of two desulfuration systems breaks down and cannotdesulfurize, the normal-side desulfuration system can be used for stable desulfuration for a long term, the problem that due to the fact that the desulfuration system on one side breaks down, sintering stops is thoroughly solved, the cost generated from starting and stopping of sintering is saved, and it is ensured that the yield of sinter cannot be influenced.

Description

technical field [0001] The invention relates to a device for operating a single-side tower of dense-phase tower desulfurization equipment, and belongs to the technical field of dense-phase tower desulfurization equipment in the metallurgical industry. Background technique [0002] Dense phase tower desulfurization technology is a relatively mature semi-dry flue gas desulfurization process. The desulfurization equipment is installed at the rear end of the electrostatic precipitator at the head of the sintering machine to remove sulfur dioxide in the sintering flue gas. [0003] At present, this process has been successfully applied on large-scale sintering machines in many domestic steel plants. The desulfurization process generally consists of two separate desulfurization systems, each desulfurization system has a dense phase desulfurization tower, a pulse bag filter and a set of independent desulfurization ash conveying device. The dense-phase desulfurization tower is main...
