Abstract: An object of the present invention is to provide an accumulator including a flow damper which is capable of performing a control so that a vortex may not be formed in a vortex chamber at the time of a large flow injection without requiring huge labors and fabrication costs. The flow damper is configured of a colliding jet controller (a bevel or a projection) for controlling a colliding jet composed of a jet from a large flow pipe and a jet from a small flow pipe flowing into a vortex chamber at the time of a large flow injection so that the colliding jet may proceed directly to an outlet without forming a vortex in the vortex chamber. The colliding jet controller is provided at a junction of an inner surface of the small flow pipe and an inner surface of the vortex chamber.

Abstract: A heat exchanger coil pipe is internally cleaned off dirt deposits by forcing ice and water to pass the pipe. A system for carrying out the cleaning comprises a suction pump, a wastewater collecting tank, a suction hose for connection between the waste and wash water collecting tank and a heat transfer medium inlet or outlet of the pipe and an ice-feeding hose provided at one end with a hopper and connectable at the other end to the heat transfer medium outlet or inlet pipe. In the state of the suction hose being connected to the heat transfer medium inlet or outlet and the suction hose being connected to the heat transfer medium outlet or inlet, ice and water are supplied from the hopper and drawn into the ice by suction from the suction pump to flow in the coil pipe and collected into the wastewater collecting tank.

Abstract: The present invention is one for providing an apparatus and a method which make it possible to remove a foreign object or matter such as scale attached on an inner surface of a pipe easily for a short period of time by means of simple equipment and manner, and constituted as follows. Specifically, a holder (11) is attached onto an end of a pipe (P), an abrasion assisting member (16) fixed to a tip end of a support arm (15) is inserted into the pipe (P) by use of the holder (11) and stopped at an area (A) where oxide scale (S) is generated in a large amount. Then abrasive is sent with pressure into the pipe (P) by a blast device (14), and thus a flow rate of the abrasive in the scale-abraded area (A) is increased to abrade and remove the oxide scale (S) securely. Moreover, if required, a spiral groove (17) is formed on an outer circumference of the abrasion assisting member (16) to increase centrifugal force of the abrasive.

Abstract: A scale removing device for removes scale adhering to the interior of a shell-and-tube-heat-exchanger-type steam generator. The scale removing device is provided with a flexible lance (58) holding a high-pressure water hose (91) movable with respect to a tube plate, tube support plates, and heat-transfer tubes. A cleaning head (60) is mounted to the forward end of the flexible lance. Formed inside the cleaning head is a cavitation generating nozzle hole (99a, 99b) communicating with the high-pressure water hose. Bubbles are generated at the time of cleaning, and the impact pressure generated when the bubbles collapse is propagated to remove scale over a wide range.
