Description

本発明は、高温又は低温の機器や配管の外周面に施工してある断熱材の劣化度を診断する断熱材劣化診断方法と、高温又は低温の機器や配管の外周面に施工してある断熱材の劣化度を診断可能な断熱材劣化診断設備と、断熱劣化度を診断可能な断熱材に関する。 The present invention relates to a thermal insulation deterioration diagnosis method for diagnosing the degree of deterioration of thermal insulation material applied to the outer peripheral surface of high-temperature or low-temperature equipment and piping, and heat insulation applied to the outer peripheral surface of high-temperature or low-temperature equipment and piping. The present invention relates to a heat insulation deterioration diagnosis facility capable of diagnosing the deterioration degree of a material and a heat insulation material capable of diagnosing the heat insulation deterioration degree.

電力や化学プラントなどにおいて機器や配管に施工してある断熱施工済み断熱材は、長期使用のうちに雨水や結露水が侵入して断熱性能が劣化し、熱エネルギーのロスが生じるので、適宜、断熱材の劣化度を診断して、必要に応じて交換するなどのメンテナンスを実施する必要がある。
断熱材の劣化度を診断する従来の技術では、高温又は低温の機器や配管の外周面に施工してある断熱材の一部をサンプルとして取り出して、そのサンプルの熱伝導率や含水率などの物性を調べたり（以下、従来技術１という）、断熱施工済み断熱材の表面温度を赤外線サーモグラフィ装置で求めたり、断熱施工済み断熱材の放散熱量を熱流量計や表面温度計などの計測機器で求めて（以下、従来技術２という）、その劣化度を診断している（周知・慣用技術であり、先行技術文献情報を開示できない）。 Thermal insulation that has been installed on equipment and piping in electric power and chemical plants, etc., because rainwater and condensed water enter during long-term use, resulting in deterioration of thermal insulation performance and loss of thermal energy. It is necessary to perform maintenance such as diagnosing the degree of deterioration of the heat insulating material and replacing it as necessary.
In the conventional technology for diagnosing the degree of deterioration of a heat insulating material, a part of the heat insulating material applied to the outer peripheral surface of a high-temperature or low-temperature device or piping is taken out as a sample, and the thermal conductivity, moisture content, etc. of the sample are taken. Investigate the physical properties (hereinafter referred to as Conventional Technology 1), obtain the surface temperature of the heat-insulated heat insulation material with an infrared thermography device, and measure the amount of heat dissipated in the heat-insulated heat insulation material with a measuring device such as a heat flow meter or surface thermometer. In search (hereinafter referred to as Conventional Technology 2), the degree of deterioration is diagnosed (a well-known and commonly used technology, and information on prior art documents cannot be disclosed).

上記従来技術１は、サンプルとして取り出した断熱材の物性を調べるので、高い信頼性で劣化度を診断できるが、断熱施工済み断熱材からサンプルを取り出しても支障がないように、診断時期がプラントなどの稼働停止時に限られるといった制約を受け易いとともに、物性を調べるために時間や経費も掛かり、劣化度を簡便かつ迅速に診断できない欠点がある。
また、上記従来技術２は、非破壊で断熱施工済み断熱材の劣化度を診断できるが、断熱材を施工してある現場に、高価な赤外線サーモグラフィ装置や計測機器を搬入して設置する必要があるので、それらの装置や機器を搬入できる診断時期や、それらの装置や機器を設置して診断できる箇所に制約を受け易いとともに、それらの装置や機器の操作にも熟練を要し、劣化度を簡便かつ迅速に診断できない欠点がある。
本発明は上記実情に鑑みてなされたものであって、断熱施工済み断熱材の劣化度を簡便かつ迅速に診断できるようにすることを目的とする。 Since the above prior art 1 examines the physical properties of the heat insulating material taken out as a sample, the degree of deterioration can be diagnosed with high reliability, but the diagnosis time is set in the plant so that there is no problem even if the sample is taken out from the heat insulating material that has been heat-insulated. There is a drawback that it is easy to be subjected to restrictions such as when the operation is stopped, and it takes time and expense to investigate the physical properties, and the degree of deterioration cannot be diagnosed easily and quickly.
Moreover, although the said prior art 2 can diagnose the deterioration degree of the non-destructive heat insulation material after heat insulation construction, it is necessary to carry in and install an expensive infrared thermography apparatus and measurement equipment in the field where the heat insulation material is constructed. Therefore, it is easy to be restricted by the diagnosis time when these devices and equipment can be carried in, and the locations where these devices and equipment can be installed and diagnosed, and the operation of these devices and equipment requires skill and the degree of deterioration. There is a drawback that cannot be diagnosed simply and quickly.
