摘要： Piping support of gas turbine steam cooled combustor is improved such that, even when the piping support is damaged by combustion vibration, piping is prevented from dropping so as to avoid the occurrence of fractions thereof from entering into the turbine portion. An outer fitting member (11) is fixed to the wall surface of a tail tube (102) by welding (82, 83). A ring (12) is pinched inside the outer fitting member (11) to be fixed by welding (80). The ring (12), having an inner diameter slightly larger than the outer diameter of the steam piping (101), is fitted in around the steam piping (101) to be fixed by welding (81) at three places. The steam piping (101) is fixed to the ring (12), the ring (12) is fixed to the outer fitting member (11), and the outer fitting member (11) is fixed to the tail tube (102), such that the steam piping (101) is supported to the tail tube (102). Thus, even when the welding (82, 83) is detached by combustion vibration, the outer fitting member (11) remains fixed to the steam piping (101).

摘要： PROBLEM TO BE SOLVED: To provide a snow-attach preventing apparatus for a suction filter of gas turbine capable of preventing filter from being clogged with snow by removing the snow inflowing from the suction port at the front face, so as not to make attachment to the filter. SOLUTION: A house 10 for a gas turbine is furnished with a suction port 17 to suck the air 30, and water drops and snow are removed from a room 24 by a demister 1, and the air removed of dust by a filter 16 flows to a duct inlet 23 from a room 25 and is led to the gas turbine. A water-sprinkling nozzle for sprinkling water in summer, etc., is installed at the inlet of the suction port 17, while another 7 for sprinkle water to the snow inflowing in winter is installed at the entrance to the room 24. The demister 1 is installed on the front face of the filter 16, to remove also permeating water drops, rainwater, and snow. The demister 1 is formed with an eliminator, a water louver, or a wire pad, and the inflowing snow is allowed to contain water using the nozzle 7, while the snow attached to the demister 1 is dropped off by the weight of the water contained, and will not attach to the filter 16. The differential pressure between inside and outside the filter 16 will not rise either.

摘要： PROBLEM TO BE SOLVED: To prevent a support component from entering gas turbine part by preventing the support component from disengaging from a pipe when a support is damaged by a combustion vibration. SOLUTION: An outer side attaching member 11 is fixed to a wall surface of a tail wall 102 by welds 82, 83, a ring 12 is put inside the tail wall 102, and the attaching member 11 and the ring 12 are fixed to both side by a weld 80. The ring 12 has a diameter somewhat larger than that of a steam pipe 101 and inserted to the pipe 101, and an outer periphery of the pipe 101 and an inner periphery of the ring 12 are fixed to each other by weld 81 at three points. As a result, since the pipe 101 is fixed to the ring 12, the ring 12 is fixed to the outer side attaching member 11, and the outer side attaching member 11 is fixed to the wall surface of the tail wall 102, the pipe 101 is supported by the attaching member 11. Further, even if the welds 82 and 83 are disengaged due to vibration or the like, since the attaching member 11 is fixed to the ring 12, the attaching member 11 is prevented from falling from the pipe 101.

摘要： PROBLEM TO BE SOLVED: To prevent reduction in membrane flux due to clogging, breakage, etc., of membranes, to stabilize the treatment and to improve efficiency of the treatment by adding a calcium compound to waste water contg. sulfuric acid in two stages, i.e., in a first stage and a second stage respectively to adjust pH of the waste water to specified values in the first and second stages respectively, subjecting insoluble matter thus formed in the resulting water to membrane separation to obtain permeant water and discharging the permeant water to the outside of the treatment system as treated water. SOLUTION: In the system of this treatment, waste water contg. sulfuric acid is introduced into a first reaction vessel 1 fitted with a pH meter IA and thereafter, a calcium compound such as Ca(OH)2 , or the like is added to the waste water to adjust the pH to 4 to 6, or preferably, about 4.5 to 5.5. Then, this waste water is further introduced into a second reaction vessel 2 fitted with a pH meter 2A and similarly, a calcium compound is added to the waste water to adjust the pH to 6.5 to 8. The resulting water is treated with a circulation vessel 3 and a membrane module 5, to obtain membrane permeant water. The permeant water is transferred to a permeant water tank 6 for backwashing to discharge the permeant water from the tank 6 to the outside of the system as treated water. By performing the addition of a calcium compound to waste water contg. sulfuric acid and the adjustment of pH of the waste water in two stages, the dissolution amounts of scale-forming components can sufficiently be reduced and also, deposition of coarse particles can be prevented from occurring. Thus, trouble due to scale formation, membrane breakage, etc., can be prevented from being caused.

摘要： PROBLEM TO BE SOLVED: To significantly reduce the consumption of a cleaning agent, and dispense with a specical chemical-resistant member as a material for a heating installation, piping or the like by supplying a cleaning agent to and filling an untreated water and concentrated water chamber with the cleaning agent and supplying a heated water to a permeating water chamber, when cleaning a membrane module with a cleaning agent. SOLUTION: When treating an untreated water by membrane separation, the untreated water is guided to the primary side 1A of a membrane module 1 through piping, and the permeating water which permeates to the secondary side 1B is delivered through a water collecting valve V-5. When cleaning the membrane module with a cleaning agent, the water collecting valve V-5, V-3, V-4 are closed and the valves V-1, V-2 are opened. Then a cleaning liquid is supplied to the primary side 1A of the membrane module 1 from a cleaning liquid tank 2 with the help of a cleaning pump 3 to replace the liquid on the primary side 1A with the cleaning liquid. After that, the valves V-1, V-2 are closed and the valves V-3, V-4 are opened. Further, a heated process water in a heated process water circulation tank 5 is circulated to the secondary side 1B of the membrane module 1 using a circulation pump 6 and thereby the cleaning liquid on the primary side 1A is heated to increase the effect to clean the membrane.

摘要： PROBLEM TO BE SOLVED: To decrease the frequency of the exchange of a membrane by cleaning the membrane, soiled by the continuation of treatment, with a cleaning solution containing oxalic acid to improve the recovering ratio of the membrane by cleaning and to prolong the period for executing chemical cleaning. SOLUTION: At first an alkali cleaning solution in an alkali storage tank 9 is supplied to the water permeating side of a membrane separation device 6 by driving a pump 11, returned to the alkali storage tank 9 through a pipe line and circulated for a fixed time. Next, the alkali cleaning solution is fed to the concentrated water side and circulated. After that, the cleaning solution is switched to an acid cleaning solution, the acid cleaning solution in an acid storage tank 10 is circulated between the acid storage tank 10 and the membrane separation device 6 in the same manner to clean the membrane. By cleaning in this way, the membrane-soiling material specific to the flu gas desulfurization waste water is removed and the membrane performance is recovered. And a cleaning waste water generated by the cleaning of the membrane is treated without providing an additional waste water treating device by using the treating process of the flue gas desulfurization waste water.
