摘要： PURPOSE:To remove dirt by utilizing reoperating time by interposing a heat exchanger between a water intake tube and a drain tube in a pump apparatus for inputting non-treated water such as sea water, sewage, etc., to be used for heat exchanging, and so providing a by-pass tube as to round about the exchanger. CONSTITUTION:Non-treated water W normally input from an intake port 21 by operating an intake pump 10 is introduced to a heat exchanger 4 through a strainer 41, heat exchanged with liquid L to be heat exchanged in the exchanger 4, and then discharged to an intake source through a drain tube 3. Then, when an operation of a pump apparatus 1 for a specific period is once finished and then restarted, an inlet valve 61 and an outlet valve 62 are closed, first, second by-pass valves 63, 64 of a by-pass tube 5 are opened, and the pump 10 is restarted in this state. Thus, the water W is discharged to an intake source through the tube 5 and the tube 3. In this case, slimes produced on walls of the tubes are removed to clean the tubes.

摘要： PROBLEM TO BE SOLVED: To provide a simple system which is excellent in the coefficient of performance of the refrigeration cycle and dispenses with a circulation pump or the like by successively connecting a compressor, a condenser, an expansion valve, and an evaporator, providing a second condenser between the condenser and the expansion valve, and extracting the mixed gas of low boiling point stored in the condenser to the second condenser through a pipe. SOLUTION: A compressor 1, a condenser 2, a second condenser 3, an expansion valve 4, and an evaporator 5 are successively connected. The non-azeotropic mixed refrigerant gas compressed by the compressor 1 is partly stagnated in the vicinity of a refrigerant outlet 2b of the condenser 2, and extracted by a pipe 13, and discharged to the second condenser 3. The condensed high boiling point mixed refrigerant liquid stored in a lower part of the condenser 2 is introduced into the second condenser 3 by a pipe 12. The refrigerant gas evaporated in an evaporation part 3v of the second condenser 3 is introduced into an intermediate port 1c of the compressor 1 to suppress the pressure fluctuation. As condensation in the second condenser 3 is advanced, the differential pressure is generated between the condensers, extraction to the second condenser 3 is promoted, and the heat transfer performance is improved. The coefficient of performance of the refrigeration cycle can be improved.

摘要： PURPOSE:To provide the evaporating device, in which an ice layer is not formed around the outer periphery of a heat transfer tube, the structure of which is strong, and in which vibration related to fluid is not caused and LNG is distributed uniformly to respective heat transfer tubes. CONSTITUTION:The evaporating device for low-temperature liquefied gas is constituted of a heat transfer tube 30, arranged vertically and liquefied gas is conducted to flow therethrough, while heating fluid is supplied to flow down along the outer peripheral surface of the same tube 30 to evaporate the liquefied gas through heat exchange between the heating fluid and the liquefied gas. The heat transfer tube 30 is constituted of a triple structure made by an inner tube 31, an intermediate tube 32 and an outer tube 33. The inflow port 31a of the liquefied gas is provided at the top of the inner tube 31 and an outflow port 33c, opened toward the inside of the intermediate tube, is provided at the lower end of the same. The lower end of the intermediate tube 32 is formed so as to be a closed structure having a bottom and an outflow port 32a, opened toward the inside of the outer tube 33, is provided at the top of the same tube 32. The top of the outer tube 33 is formed so as to be a closed structure equipped with a ceiling and the send-out port 33c of evaporated gas is provided at the lower end of the outer tube 33.
