Four-way shell-and-tube heater with ultrasonic generator

This article offers a heat-exchanger of improved design which allows reducing time between overhauls and maintenance. Since to date, the challenge of providing enterprises and public utility installations with heat-transfer media of required parameters is the most pressing. The collection chamber is equipped with a variable frequency ultrasonic radiator. Bays are installed with the possibility of extracting them. The case is made as one-piece and enclosing all bays. Heat exchange sections are made in the form of sectors. The dividers are equipped with windows that provide the flow of the annular medium in the opposite direction to the flow of the pipe medium. Tests were conducted on a four-way shell-and-tube heat exchanger. The heater was disassembled and inspected, after inspection it was found that scale on the heating surface was completely absent. As a result of the analysis, we can conclude that the design efficiency of the four-way shell-and-tube heater. When working on soft water and ultrasonic protection, there is no carbonate scale on the heating surface. When developing a combined vertical heat exchanger, a comparison was made with high-speed water sectional heat exchangers. The task of creating a simple and cheap design of the heat exchanger was performed by simplifying the design of the heat exchange sections and reducing the metal consumption. The stated technical problem was solved by improving the multi-pass heat exchanger with an ultrasonic emitter, which has a casing and heat-exchange sections in the form of tube bundles with tube sheets at the ends.
