Dry quenching coke cooling and humidifying system

Abstract

The invention relates to a dry quenching coke cooling and humidifying system which comprises a belt conveyor I, a humidifying chute, a belt conveyor II and a coke water adding device. The tail part of the belt conveyor I is a dry quenching coke receiving end, the head part of the belt conveyor I is connected with the tail part of the belt conveyor II through the humidifying chute, and the head part of the belt conveyor II is a wet and cold coke output end; the coke water adding device comprises a water pump, a water conveying pipeline and a plurality of nozzles; one end of the water pump is connected with a water source, and the other end of the water pump is connected with the plurality of nozzles which are arranged above the belt conveyor I, the humidifying chute and the belt conveyor II along a dry quenching coke conveying path through a water conveying pipeline. The humidifying process of the dry quenching coke is decomposed into a cooling process and a humidifying process, so that the purposes of cooling and water adding humidifying of the dry quenching coke are better achieved in the conveying process of the belt conveyor.

Description

technical field [0001] The invention relates to the technical field of dry quenching coke, in particular to a cooling and humidifying system for dry quenching coke. Background technique [0002] Normally, the coke in the CDQ furnace is discharged through the coke discharge device and output through the belt conveyor. The coke discharge temperature of CDQ is generally below 200°C, and the moisture content is 0% to 0.5%. Therefore, the dust discharge during the transfer process is large, resulting in high dust removal pressure in the downstream system. An effective way to solve the above problems is to humidify coke CDQ. [0003] At present, the main method for humidifying coke in CDQ is to spray water into the coke. However, it also brings about two problems: one is that water will generate a large amount of water vapor when it encounters coke at 200°C, resulting in a bad production environment; the other is that a large amount of water spraying makes it difficult to separa...
