Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat shield cover, and more particularly, to a heat shield cover that covers a combustion gas pipe of a gas turbine reaching 600 to 1200 degrees and an exhaust pipe of an internal combustion engine for safety. is there.

[0002]

[Prior art]

 As described above, the combustion gas pipes and exhaust pipes of the gas turbine, which become hot, may cause a fire and may adversely affect the human body and surrounding equipment, so the heat insulating material is covered. .

[0003]

[Problems to be solved by the device]

 The above-mentioned heat insulating material is closely attached to the combustion gas pipes and exhaust pipes, and is easily deteriorated with time because it is exposed to a fairly high temperature.Moreover, unless a thick heat insulating material is used, a sufficient heat shielding effect cannot be obtained. I can't get it. Therefore, it is an object of the present invention to provide a heat shield cover which is relatively thin and can be easily attached to a combustion gas pipe, an exhaust pipe, etc., is less likely to deteriorate over time, and has a sufficient heat shield effect.

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION The present invention provides the above-mentioned object with a heat shield cover in which the entire heat insulating material such as ceramic fiber is wrapped with a surface material such as aluminum foil, stainless thin plate, heat resistant cloth, and the surface material is covered with a metal net. Solved. Usually, a fixing means such as a fixing wire or a fixing band for fixing the cover to an exhaust pipe is attached to the surface material. In addition, an auxiliary metal plate is arranged below the heat insulating material as needed.

[0005]

[Work]

 The cover is covered with an exhaust pipe or the like, and is fixed through fixing means. Since a metal net exists between the surface material and the exhaust pipe to form a gap, heat insulation is promoted.

【Example】

 A preferred embodiment of the present invention will be described with reference to the accompanying drawings. In the figure, reference numeral 1 denotes a heat shield cover according to the present invention, which is formed into a shape corresponding to the shape of a combustion gas pipe, an exhaust pipe or the like on which the heat shield cover is fitted. The heat shield cover-1 is provided with a fixing means to a combustion gas pipe or an exhaust pipe. In the illustrated example, metal rings 2 are installed on both sides of both ends of the heat shield cover 1 by caulking or the like, and a fixing wire 3 is passed therethrough. The heat shield cover 1 can be fixed to the exhaust pipe by connecting the fixing wires 3 to each other below the exhaust pipe. Instead of the fixing wire 3, a band may be attached and fixed by connecting the band on the lower side of the exhaust pipe or the like.

The heat shield cover 1 is formed by wrapping a heat insulating material 4 such as a ceramic fiber with a surface material 5 such as an aluminum foil, a stainless thin plate, or a heat resistant cloth, and covering the whole with a metal net 6. The metal net 6 protects the surface material 5 to prevent its damage and the like, and also maintains a gap between the surface material 5 and the combustion gas pipe 10 to prevent heating due to close contact. . The end of the surface material 5 is overlapped so that the heat insulating material 4 does not overflow.

Reference numeral 7 denotes an auxiliary plate made of thin stainless steel or the like, which is arranged on the lower side of the heat insulating material 4, in other words, on the inner bottom portion of the surface material 5. The auxiliary plate 7 is arranged as needed when the subject to be covered becomes extremely hot.

The heat shield cover 1 according to the present invention has flexibility, and can be appropriately stretched when it is mounted on the combustion gas pipe 10 or the like. Then, by connecting the fixing wire 3 to the lower side of the combustion gas pipe 10 or the like, the combustion gas pipe 10 or the like is laid from the upper surface to the side surface (or, if it is installed above the ceiling, from the lower surface to the side surface). Or, it is applied over almost the entire circumference.

At this time, since the surface material 5 does not adhere to the combustion gas pipe 10 or the like due to the metal net 6, the conduction of heat from the combustion gas pipe 10 or the like is suppressed to some extent. Further, since the heat shield cover-1 includes the heat insulating material 4, heat conduction to the surface side of the heat shield cover-1 is considerably impeded, which causes a fire and a worker in the vicinity. It is possible to sufficiently prevent adverse effects on peripheral devices.

[0011]

[Effect of device]

 The present invention is as described above, and can be easily attached to combustion gas pipes and exhaust pipes that generate high heat. Moreover, a heat insulating material protected by a metal surface material and a metal net surrounding it can be used. The presence of this element has the effect of reliably blocking the conduction of heat, thereby preventing the risk of fire from occurring and the occurrence of adverse effects on peripheral equipment and the human body.
