Steel ball dust removal submerged arc furnace waste heat boiler

Abstract

A steel ball dedusting-type submerged arc furnace waste heat boiler comprises a circulating-type steel ball mechanical dedusting device. A fine-adjustment correcting plate and a rough-adjustment correcting rod of a circulating-type steel ball mechanical transporting device of the circulating-type steel ball mechanical dedusting device are arranged parallelly, the fine-adjustment correcting plate is positioned below the rough-adjustment correcting rod, and a distance between the fine-adjustment correcting plate and the rough-adjustment correcting rod corresponds to overall height of a steel ball transporting bucket. The steel ball transporting bucket in which steel balls are contained contacts with the fine-adjustment correcting plate and the rough-adjustment correcting rod to perform horizontal correcting, and then contacts with a mechanical discharging retaining wheel to provide turnover driving force through the mechanical discharging retaining wheel, in this way, after reaching an upper transverse bearing frame, the steel ball transporting bucket is enabled to be in a horizontal state through the fine-adjustment correcting plate and the rough-adjustment correcting rod, so that after the steel ball transporting bucket contacts with the mechanical discharging retaining wheel of the circulating-type steel ball mechanical transporting device, transported steel balls can be ensured to be poured into a steel ball scattering device.

Description

technical field [0001] The invention relates to the technical field of waste heat boilers, in particular to a steel ball dust removal type submerged arc furnace waste heat boiler. Background technique [0002] At present, a large amount of energy consumption is required in various industrial production fields, and the unused heat energy generated by various heat energy conversion equipment, energy-consuming equipment and chemical processing equipment in the production process will also be generated in the production process A large number of various forms of waste heat, the sources of waste heat mainly include waste heat from industrial exhaust, waste heat from high-temperature products and slag, waste heat from cooling media, waste heat generated during chemical reactions, heat energy from combustible waste gas, waste materials, waste liquids, and The waste heat of waste steam and waste water, while the average thermal efficiency of industrial boilers is only 67%, and the r...

Problems solved by technology

However, this invention has the following disadvantages: because the steel balls jump between the heating surfaces from top to bottom, the amount of steel balls output by the steel ball separation and collection device is indeterminate. Due to the deviation, the steel ball transport bucket cannot maintain a horizontal state. The steel ball transport bucket with a certain inclination angle cannot pour all the steel balls into the steel ball spreading device when passing through the mechanical unloading retaining wheel, which reduces the amount of steel balls entering the boiler, thereby reducing Dust removal effect, and waste of electricity
