Drawer type cooling device

Abstract

The invention discloses a drawer type cooling device. The drawer type cooling device comprises an upper chamber, an upper shut-off valve, a lower chamber, a lower shut-off valve and N drawer type water coolers. By fully utilizing the floating falling characteristic of dust particles in the falling process, particle dust makes contact with multiple drawer type water coolers multiple times layer upon layer when the particle dust floats down, and then a full cooling effect is achieved; the drawer type cooling device is divided into the upper chamber and the lower chamber for temporary storage, the upper chamber and the lower chamber are isolated through a middle shut-off valve, and the lower chamber is isolated from a dust discharging bin through the lower shut-off valve; the exteriors of the whole chambers are provided with winding water pipes for cooling, and the drawer type water coolers can be freely disassembled. The drawer type cooling device has the advantages that overhauling is convenient, equipment can be overhauled and replaced on line, a coke dry quenching system does not need to be stopped, continues running of the coke dry quenching system can be guaranteed, and the condition that potential safety hazards exist when overhauling personnel conduct overhauling in a high-temperature and narrow space is eliminated.

Description

technical field [0001] The invention relates to a CDQ coke powder recovery device in the field of metallurgy and a high-temperature mineral powder recovery device for a dust collector of a sintering machine. As a system for collecting high-temperature particles and dust in one-time dust removal, the high-temperature particles and dust are collected in a drawer-type water-cooled collection device. Discharging after internal cooling, especially relates to a kind of ash slag heat exchange cooling device. Background technique [0002] In the CDQ coke powder recovery and sintering machine dust collector system, the high temperature coke powder needs to be cooled during recovery, and the CDQ water-cooled sleeve cooler is a special device for cooling the high temperature coke powder. The existing CDQ water-cooled casing cooler mainly includes a cooler body, a single fork on the top to collect CDQ powder, inner and outer casings located in the cooler body, water inlet, drainage syst...
