AI Technical Summary

Technical Problem

Existing heat exchanger cleaning systems face challenges such as long cleaning times, incomplete tube cleaning due to blockages, high-pressure hazards, and reliability issues, particularly in shell-and-tube heat exchangers with numerous tubes, which complicates automation and poses safety risks.

Method used

A heat exchanger cleaning device with multiple high-pressure hoses, each driven by independent motors, allowing differential feed rates and automated positioning, along with a control unit to manage hose movement and torque to prevent slippage, ensuring simultaneous cleaning of multiple tubes while accommodating blockages.

Benefits of technology

Reduces cleaning time, enhances reliability by preventing hose damage, and ensures all tubes are cleaned efficiently, even when some hoses are blocked, improving safety and automation capabilities.

Abstract

Heat exchanger cleaning device (1) for high-pressure cleaning of the inside of the tubes (24) of a heat exchanger (W), wherein the heat exchanger cleaning device (1) comprises: a) a high-pressure unit (2), wherein the high-pressure unit (2) has at least two high-pressure hoses (58) and the high-pressure hoses (58) are each connectable at one end to a high-pressure source and have a nozzle at their other end, b) a positioning device (90) for positioning the high-pressure hoses (58), wherein the positioning device (90) comprises a feed device (100) for motor-driven movement of the at least two high-pressure hoses (58) in the longitudinal direction (LR) of the high-pressure hoses (58), wherein the feed device (100) comprises at least two drive motors (59) and the drive motors (59) each interact with exactly one high-pressure hose (58), and c) a control unit (74).which is set up to control the at least two propulsion motors (59) independently of each other.
