AI Technical Summary

Technical Problem

Traditional shell and tube heat exchangers have uneven cooling water flow rates due to the internal baffle, resulting in poor heat exchange effect and prone to scaling.

Method used

The baffle is used to replace the baffle, and the baffle is driven to adjust the position through the movable connecting frame to form a roundabout passage of cooling water, changing the flow state to reduce scaling.

Benefits of technology

By adjusting the baffle position and changing the cooling water flow state, the speed of water scale inside the heat exchanger shell is reduced and the service life of the device is extended.

Abstract

The invention belongs to the field of heat exchanger anti-scaling, and particularly relates to a heat exchanger anti-scaling device which comprises two sets of baffles, a plurality of baffles in each set are linearly arranged at equal intervals, the two sets of baffles are arranged on the upper side and the lower side in a heat exchanger shell respectively, and the two sets of baffles are staggered to form a circuitous channel for cooling water. A baffle plate in the heat exchanger is replaced by the baffle plate, when the heat exchanger works, the movable connecting frame moves on the outer side of the heat exchanger shell, the inner baffle plate can be driven to move, and the position of the baffle plate is adjusted before cooling work every time or during long-term cooling work; by means of the arrangement, the scaling speed of water in the shell of the heat exchanger is greatly reduced, follow-up operations of equipment cleaning and part replacement needed after scaling are reduced, and the service life of the device is prolonged.
