MOBILE UNIT FOR AUTOMATED CLEANING OF HEAT EXCHANGE EQUIPMENT Russian patent published in 2022 - IPC B08B9/27 B08B3/00 

FIELD: heat exchangers.

SUBSTANCE: invention relates to a device for automated cleaning of tube bundles of heat exchangers. The mobile installation for automated cleaning of heat exchange equipment includes a coordinate table designed to guide the carriage with high-pressure cleaning hoses to the section of the heat exchanger wall to be cleaned, consisting of two frames connected to each other by means of pneumatic cylinders, while the frames are equipped with caterpillars equipped with servo drives, which are designed to move the coordinate table along the tube wall of the heat exchanger, and the pneumatic cylinders serve to fix the coordinate table by spreading its frames between the wall of the heat exchanger chamber and the tube wall of the heat exchanger, at the same time, a carriage is installed on one of the frames of the coordinate table, equipped with a mechanism for moving the high-pressure hoses fixed on it in a vertical plane parallel to the tube wall of the heat exchanger and pointing them at the cleaned tubes of the heat exchanger, while the high-pressure hoses pass through the high-pressure hose supply mechanism located behind outside the coordinate table and designed to feed them inside the heat exchanger tubes during their cleaning, and, in addition, the coordinate table is equipped with sensors for the location of heat exchange tubes, a lidar designed to detect obstacles on the tube wall of the heat exchanger, a laser range finder used to inspect the inner surface of the tubes heat exchanger, and a video camera that serves to visually control the operation of the mobile unit, while the coordinate table is connected by cable to the control unit, which is located outside the heat exchanger chamber in a safe place for the operator, using which provides transmission of control signals to the caterpillar servo drives, to the high-pressure hose supply mechanism and to the carriage movement mechanism, and also with the help of this cable, signals from the heat exchange tube location sensors, lidar, laser range finder and video camera are transmitted to the control unit, while the movement of the coordinate table and the carriage is controlled both in automatic and semi-automatic mode in accordance with the algorithms embedded in the control unit.

EFFECT: expanding the scope of devices for automated cleaning of heat-exchange equipment in a confined space, including in dangerous conditions for the operator.
