Magnetization oxygen-enriched energy conservation and emission reduction system of gaseous suspension roaster

Abstract

The invention relates to a magnetization oxygen-enriched energy conservation and emission reduction system of a gaseous suspension roaster. The magnetization oxygen-enriched energy conservation and emission reduction system comprises a raw air supply fan, two multi-duct pressure equalization distribution tanks, a double-stage booster roots pump set, an intelligent PLC (programmable logic control) system and an oxygen-enriched gas output pipeline. The raw air supply fan is connected with the two multi-duct pressure equalization distribution tanks, cyclone concave-convex thermal separation magnetic groups are arranged in the two multi-duct pressure equalization distribution tanks and are connected with an inlet of the double-stage booster roots pump set by vacuum absorption pipelines, the double-stage booster roots pump set is connected with an oxygen-enriched injection point of the gaseous suspension roaster by the oxygen-enriched gas output pipeline, the raw air supply fan, an intelligent oxygen analyzer and an intelligent gas flow meter are connected with the intelligent PLC system, and the intelligent PLC system is connected with a remote computer. The magnetization oxygen-enriched energy conservation and emission reduction system has the advantages that the combustion speeds can be increased, and complete combustion can be promoted; ignition temperatures of fuel can be lowered, combustion environments can be optimized, and the service life of the roaster can be prolonged; the yield of products can be increased, the quality of the products can be improved, and the post-combustion smoke quantity can be reduced.

Description

technical field [0001] The invention belongs to the technical field of kiln equipment, and in particular relates to a magnetized oxygen-enriching energy-saving and emission-reducing system for a gaseous suspension roasting furnace. Background technique [0002] Energy shortages and climate anomalies have become the primary focus of governments at all levels and all walks of life in my country today. With the rapid growth of the global economy, the demand for energy is increasing, and energy has become a bottleneck restricting economic growth. [0003] The traditional gaseous suspension roaster uses air as the combustion-supporting medium. The oxygen content in the air is 21%, and the nitrogen content is 78%. The thermal efficiency is low, the product output is low, the energy consumption is large, and the air pollutants discharged are many. Contents of the invention [0004] The object of the present invention is to provide a magnetized oxygen-enriched energy-saving and e...
