Combined primary and secondary collecting apparatus for coal charging dust removal for tamping coke oven

Abstract

A combined primary and secondary collecting apparatus for coal charging dust removal for a tamping coke oven belongs to the technical field of environment-friendly dust removal for coking. The apparatus comprises a primary collecting hood, a secondary collecting hood, a middle partition, a gathering joint (4), a rotary cover plate, a seal cushion, and an air distribution adjuster. The primary collecting hood is arranged between oven pillar, the secondary collecting hood is arranged outside a side roof, and the primary collecting hood and the secondary collecting hood share the gathering joint. The combined primary and secondary collecting apparatus for coal charging dust removal for a tamping coke oven has the advantages that space between the side oven pillars of the tamping coke oven and space above the roof are made reasonable use, smoke collecting capacity is greatly improved, the collecting hoods are supported completely by the oven pillars, independent supports are not required, and implementing is facilitated. The fact that no hood is provided when there is dust or a dust hood experiences mismatching is changed, the scale bottleneck restricting a coke oven charging dust removal system is broken through, conditions are created for collecting coal charging smoke, the contradictions of capacity mismatching between tamping coke oven charging dust removal smoke quantity and traditional collecting hoods, influenced operation of a coke oven locomotive, and strained relation of side space of a coke oven are effectively solved, and the problem with dust collecting during coal charging of a tamping coke oven can be solved thoroughly.

Description

technical field [0001] The invention belongs to the technical field of coking environmental protection and dedusting, in particular to a primary and secondary combined collection device for tamping coke oven coal charging and dedusting. Background technique [0002] The coal charging method with the wide open side door of the ramming coke oven machine has caused its smoke and dust control to become a worldwide problem. Domestic coking plants generally have the problem that a large amount of smoke and dust emitted during the coal charging process of the ramming coke oven cannot be effectively captured. Coal dust control once became a restrictive factor for the development of tamping coke ovens, especially in the social environment where environmental protection pressure is increasingly serious and environmental protection requirements are becoming increasingly stringent. Clean production is the only way for the development of the industry. Smoke and dust collection and smoke ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a tamping coke oven coal charging and dust removal primary and secondary combined capture device, which solves the problem of the capacity mismatch between the coal charging and dust removal smoke volume and the traditional collection cover, which affects the operation of the coke oven locomotive and the side space of the coke oven machine. The tense contradiction improves the flue gas collection capacity of the collection hood, which can completely solve the problem of dust collection during the tamping coke oven coal charging operation, breaks the bottleneck that restricts the ability of the tamping coke oven coal charging dust removal system, and is suitable for all tamping coke ovens. Solid coke oven coal charging dust removal system fundamentally solves the ubiquitous environmental protection problems
