The cooling water tank of vacuum drum filter is an auxiliary cooling device supporting the filter. Its primary function is to cool the steam or high-temperature filtrate generated during the filtration process, ensuring the stable operation of the equipment and enabling material recovery.

Core Functions

Cooling and Temperature Reduction: When filtering high-temperature materials, a large amount of steam or high-temperature filtrate is generated. The cooling water tank cools these high-temperature media to a safe temperature by introducing cooling water, preventing them from damaging subsequent pipelines or equipment.

Condensation and Recovery: For the steam produced by the evaporation of high-temperature materials, the cooling water tank can condense it into a liquid. This facilitates material recovery or subsequent processing and helps reduce raw material loss.

Vacuum Degree Maintenance: If high-temperature steam directly enters the vacuum system, it may disrupt the system’s vacuum degree and affect filtration efficiency. The cooling water tank can condense the steam in advance, maintaining a stable vacuum environment for the filter.

Basic Working Principle

Medium Introduction: The high-temperature steam or filtrate formed during the filtration process is directed into the interior of the cooling water tank.

Heat Exchange: Low-temperature cooling water is continuously fed into the tank as a heat transfer medium. The high-temperature medium undergoes efficient heat exchange with the cooling water through the heat exchange tubes, completing the cooling process.

Cooled Discharge: The cooled liquid material is discharged from the bottom of the tank to enable recycling and reuse. Meanwhile, the cooling water—whose temperature rises after absorbing heat—is returned from the upper part to the cooling system for cyclic utilization.
