Abstract

The invention relates to the field of dry quenching furnaces, in particular to a novel coke powder cooling device for a one-time deduster of a dry quenching furnace, which comprises cooling pipes, a water inlet distribution box, a water outlet header, a water inlet pipe and a water outlet pipe, wherein the upper ends of a plurality of groups of parallel cooling pipes are hung on the upper part of a machine shell, and the lower ends are free ends; the water inlet pipe is connected with the water inlet distribution box which is connected with the plurality of groups of cooling pipes; and the water outlet pipe is connected with the water outlet header. The novel coke powder cooling device has the advantages that: the cooling device overcomes the structural defect of a cooling sleeve, increases a cooling area by connecting a plurality of cooling pipes with water-cooling walls in parallel, improves the cooling efficiency, has large treatment capacity in a unit time, reduces maintenance workload, can be used reliably for a long time, and is particularly suitable for a large-scale dry quenching device.

Description

technical field

[0001] The invention relates to the field of dry coke quenching furnaces, in particular to a novel coke powder cooling device for the primary dust collector of the dry quenching furnace. Background technique

[0002] The coke powder cooling device is an important equipment in the coke dry quenching device. After exchanging heat with coke, the high-temperature circulating gas contains a large amount of coke powder at about 900°C. The primary dust collector collects the high-temperature coke powder with a particle size greater than 3mm in the circulating gas Come down, cool down to below 300°C and discharge through the coke powder cooling device.

[0003] In the traditional coke dry quenching device, the high temperature coke powder collected by the primary dust collector is cooled by cooling jacket. The cooling jacket is an inner and outer two-layer water jacket, and the middle layer is the cooled high-temperature coke powder. The cooling speed of this kind ...
