Coat-pollers at iron mills are specialized environmental equipment designed for the contamination of coke from furnaces during processes such as iron refining, corrosion, etc. The application of low-pressure pulsation bag-based dust removal techniques allows energy-efficient collection of coke particles above 0. 1 m and achieves a stabilization of emission concentrations below our low emission standard of 10 mg/nm3. The equipment is widely used in high dust-producing areas, such as furnace tanks, focal troughs and sifting buildings, and is central to iron refining dust management。
I. System composition and rationale
The iron mill's coke collection equipment consists mainly of boxes, filters, ash-clearing systems, ash-cows and ash-relaying devices. When dust-containing gases enter the scrubber through the wind pipe, the coke powder is prevented from remaining on the surface of the electrostatic filter, and the cleaner gas is released through the clean gas chamber. The ash removal system controls pulse blowers through plc, which uses compressed air instant blowing filters to remove the coke powder from the dust. The collected coke is delivered to the storage through shaving machines, combat lifts, which can be treated wetly and returned directly for the burning of the ingredients or for the sale of the consignment for recycling。
Key technical characteristics
1. Preserve anti-explosive design: for the high corrosive properties of the coke powder, glass steel or stainless steel is used in the case; explosive excretion devices and nitrogen protection systems are integrated to effectively reduce the blast risk。
2. Smart control systems: real-time monitoring of operational parameters through the earth station plc to support automatic wind regulation to match production loads and to optimize the ash cycle。
3. Process synergism: in the dry-out system, pre-loading of the bag surface to the coke layer to avoid adhesives; use of piped heat-resistant measures to ensure stable winter operations in the northern region。
