Embodiment Construction

[0009] Before selecting the combination of the coke pusher dust removal system and CDQ dust removal system to share a set of dust removal ground station technology, firstly determine the amount of flue gas generated by CDQ, its finished product transfer system, and push coke through calculation, and then according to the coke The working system of furnace coke pushing and CDQ determines the production sequence of the two production processes, and makes a combined sequence table, and then judges whether there is any overlap in the production process according to the sequence table. If there is no overlap, follow the The equipment parameters of the dust removal ground station are selected for the maximum air volume of the two processes. If there is overlap, the equipment parameters of the dust removal ground station are designed according to the simultaneous operation conditions, and finally the corresponding valves and automatic control detection devices are set.

Abstract

The invention discloses a transformation method for a coke dry quenching dedusting system and a coke pushing dedusting system, and belongs to the technical field of metallurgical industry coking. A coke pushing dedusting adjusting valve is arranged on a coke pushing dedusting pipeline, and a coke dry quenching dedusting adjusting valve is arranged on a coke dry quenching dedusting pipeline. By controlling the coke pushing dedusting adjusting valve and the coke dry quenching dedusting adjusting valve to open and close in a dedusting ground station, the effect that the coke dry quenching dedusting system and the coke pushing dedusting system share one set of dedusting ground station is achieved. The method has the advantages that the technology that the coke pushing dedusting system and the coke dry quenching dedusting system are integrated and share the set of dedusting ground station is adopted, and the problems that environment dedusting systems are large in occupied area, high in investment and operation cost and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of coking in the metallurgical industry, and in particular relates to a transformation method of a dry coke quenching and coke pushing dust removal system. It is suitable for the situation that the coking process CDQ and coke pushing in the iron and steel industry can completely stagger the production sequence. Background technique [0002] With the gradual advancement of national energy conservation and emission reduction policies, CDQ technology in the metallurgical industry has been widely promoted and applied. CDQ produces a large amount of dust during coke loading and finished coke transfer, causing serious environmental pollution. Therefore, the CDQ environment The setting of the dust removal system is inevitable. The nature of the dust generated during the CDQ production process and its finished product transfer process is similar to the dust generated by coke oven pushing. It is technically feasible...
