摘要： PROBLEM TO BE SOLVED: To provide a heat exchanger capable of maintaining high heat-exchanging efficiency even with the small amount of steam supplied to the heat exchanger.
SOLUTION: The heat exchanger 1 is connected to a steam supply pipe 2 and a fluid discharge pipe 3. The steam supply pipe 2 is connected to a jetting nozzle 6 through a steam turbine 4, an outlet pipe 11 and an automatic opening and closing valve 10. The fluid discharge pipe 3 is connected to an impeller 14 of the steam turbine 4 through a vapor-liquid separator 15, a steam flow meter 18 and a control valve 19. When the amount of steam supplied from the steam supply pipe 2 to a jacket part 9 becomes small, the small amount of steam is jetted from the jetting nozzle 6 by closing of most of the automatic valves 10, thereby maintaining the convection of steam in the jacket part 9.

摘要： PROBLEM TO BE SOLVED: To reduce the temperature of superheated steam uniformly by coupling a cooling fluid injecting part with suction part of an ejector and fixing vanes for swirling the mixture fluid of steam flowing downward to the outlet side of an ejector and cooling fluid to a steam pipeline. SOLUTION: An ejector 4 disposed in a steam pipeline 3 having an inlet 1 and an outlet 2 is with revolving vanes 5 on the outlet side and provided with a cooling fluid injecting part 6 at the suction part 10 of the ejector 4. The revolving vane 5 is simply required to impart the mixture fluid of the steam flowing downward from the ejector 4 and the cooling fluid with a swirl. Steam flow is throttled through a nozzle 9 to increase the speed and sucks cooling fluid from the cooling fluid injecting section 6 in a suction chamber 10 and then pressure is recovered at a diffuser section 11. Consequently, mixing of steam and cooling fluid is accelerated by the revolving vanes 5 and the mixture is supplied to a specified position from the outlet 2. According to the structure, the cooling fluid is mixed with steam while being dispersed uniformly over the entire steam and the temperature of steam can be reduced uniformly.

摘要： PROBLEM TO BE SOLVED: To reduce pressure drop of fluid flowing down from the inlet to the outlet and to sufficiently keep a passing-through flow rate to an outlet side by providing a flow straightening passage at a place where the fluid falls down between a filter part and the outlet. SOLUTION: Plural first flow straightening passages 5 are provided in the inner space of a triangular pyramid-shaped filter 12. Besides, second flow straightening passages 6 are arranged at the outlet 2 side of the flow straightening passages 5. Relating to the fluid allowed to flow in from the inlet 1, foreign matters are caught with the filter 12, and the fluid where the foreign matters are removed flows down from the outlet 2 via the filter 12 and the flow straightening passages 5, 6. Plural disks 13 are concentrically arranged in a doughnut shaped space 8 at the outlet 2 side of the passage 7 to form a foreign matter storage. The fluid incorporating the foreign matters allowed to flow in from the inlet 1 is circulated with a guide blade member 9 and the foreign matters having large mass are collected at the outside of the passage 7 and stored in the doughnut shaped space 8. The fluid where the foreign matters are removed via the filter 12, is straightening while it passes through the flow straightening passages 5, 6 and disturbance of the fluid is decreased.

摘要： PROBLEM TO BE SOLVED: To reduce pressure loss of a fluid which flows down from an inlet to an outlet, and ensure a sufficient bypassing flow rate toward the outlet side by spring energizing a valve element installed on an outlet side of an annular valve seat, seating it on an annular valve seat, and arranging a rectified passage on a position where the fluid flows down between the valve element and the outlet. SOLUTION: In the case where a fluid flows down from an inlet 1, valve elements 5, 6 are seat on an auxiliary valve element 7, an annular valve seat 4, and a valve element 6 in the case where its fluid pressure is nearly equal to zero, and the fluid is not bypassed the outlet 2. In the case where fluid pressure is raised, a communicating hole 12 is opened by the auxiliary valve element 7 against a spring 13 having a small spring constant, and the fluid flows down from the inlet 1 to the outlet 2. When the fluid pressure is raised more, the valve elements 5, 6 are released from the annular valve seat 4 against springs 9, 10, and many fluids flow down to the outlet 2 side. In this time, the fluids which flow down to the outlet 2 is straightened while a straightening passage 15 is passed so as to prevent turbulence of the fluid.

摘要： PROBLEM TO BE SOLVED: To surely deliver drain on the way of a piping for a fluid which flows down at high speed by forming a loop part having a prescribed curvature diameter on the piping, and arranging an orifice on the lowest end part of the loop part, in a device for delivering the drain from the piping such as steam piping and the like. SOLUTION: A loop part 2 is formed on one part of a fluid piping 1, and an orifice 3 is arranged on the lowest end part of the loop part 2 so as to constitute an orifice trap. The loop part 2 is connected to the fluid piping 1 by connecting flanges 4, 5, and also its all circumference is formed in nearly constant curvature diameter. A vertical downward pipe 6 is connected to the lowest end part of the loop part 2, and an orifice plate 7 provided with the orifice 3 is installed therein. Drain and steam which flow down in the fluid piping 1 are turned in the loop part 2 at flow speed according to a pressure condition in the fluid piping 1, and thereby, the drain is led to the outer peripheral part of the loop part 2 by centrifugal force, flows down toward the vertical downward pipe 6 preferentially, and is delivered bypassing the orifice 3.
