A containment tank assembly is described that includes a tank including an inner surface and a cleaning apparatus mounted to the tank. The cleaning apparatus includes an elongate arm and a rotary spray head assembly rotationally coupled to an end of the elongate arm. A rotating nozzle assembly is rotationally coupled to the rotary spray head. A magnetic field source is coupled to the rotary spray head so as to generate a spatially changing magnetic field in accordance with a rotation of the rotary spray head assembly in relation to the end of the elongate arm. A magnet field sensor is carried in a fixed relation to the elongate arm. The magnetic field sensor, in operation, generates a sensor signal that varies in accordance with the spatially changing magnetic field in accordance with the rotation of the rotary spray head assembly.

A method for manufacturing a water-absorbent resin includes a cleaning step of cleaning the inside of a heat exchanger that is connected to a vessel holding an aqueous gel-like polymer as a precursor of the water-absorbent resin and is configured to cool a gas containing the polymer generated in the vessel. The heat exchanger, and includes: a plurality of pipes that have an elongated path through which the gas passes, in which the gas is cooled due to heat dissipation during passage through the paths; a chamber that is arranged above the plurality of pipes and is in communication with openings at upper ends of the plurality of pipes; and a cleaner that sprays a cleaning liquid in the chamber. The cleaning step includes at least cleaning the inside of the chamber by spraying the cleaning liquid from the cleaner in the chamber.

A cavity cleaning and coating system for safely and efficiently cleaning and coating the interior of a cavity without requiring entry of any workers. The cavity cleaning and coating system generally includes a mount which is coupled with a movable arm of a vehicle. The mount includes an inner plate, which is coupled to the arm, and an outer plate. A shaft is coupled to the outer plate. The mount is adjustable independently of the arm of the vehicle, including outwardly, inwardly, and rotatably. A spray head is connected to the shaft. The spray head is rotatable and includes a dispenser for dispensing fluids. The vehicle is positioned near a cavity to be treated. The mount is adjusted for optimal positioning of the spray head. The spray head is lowered into the cavity to dispense a cleaning fluid and, after the cleaning fluid has dried, a coating fluid.
