Intelligent fully-enclosed wet-process coke quenching and integrated recycling equipment

Abstract

The invention discloses intelligent fully-enclosed wet-process coke quenching and integrated recycling equipment. The intelligent fully-enclosed wet-process coke quenching and integrated recycling equipment comprises an explosion-proof valve, an enclosed coke quenching tower and waste gas recycling equipment, wherein the explosion-proof valve is arranged above the enclosed coke quenching tower; nitrogen gas pipelines are arranged in the enclosed coke quenching tower, and comprises a first nitrogen gas pipeline and a second nitrogen gas pipeline; an upper flushing pipeline and a lower flushingpipeline are arranged under the nitrogen gas pipelines; flushing valves are arranged on the upper flushing pipeline and the lower flushing pipeline; a pressure sensor is arranged at one side of the lower flushing pipeline; a steam recycling pipeline and a baffle plate device are arranged between the upper flushing pipeline and the lower flushing pipeline; the baffle plate device is arranged underthe steam recycling pipeline, and an electric valve is arranged on the steam recycling pipeline. The intelligent fully-enclosed wet-process coke quenching and integrated recycling equipment has the advantages that the waste of gas, steam, fine coke and water is avoided, the residual heat, fine coke, waste gas and water can be recycled in an integrated way, the waste of resources is avoided, and the good economic benefit is created.

Description

technical field [0001] The invention relates to a coke quenching and waste gas recovery equipment, in particular to an intelligent fully enclosed wet coke quenching and comprehensive recycling equipment. Background technique [0002] At present, the treatment methods for the cooling of red coke in the coking industry are traditional wet quenching and dry quenching. The method of wet coke quenching is to spray a large amount of water on the red coke to cool down and quench coke in an open coke quenching tower. In the atmosphere, the emission of steam causes waste of energy, and the exhaust gas causes serious air pollution. Dry quenching is a method of using inert gas to cool red coke. In the process of CD quenching, red coke is loaded from the top of the CD quenching furnace, and the low temperature inert gas is blown into the cooling chamber of the CD quenching furnace by a circulating fan. In the coke layer, the heat of the red coke is absorbed, and the cooled coke is dis...
