Abstract
Described is an apparatus and method for detecting leaks in a storage tank or containment of the type having a removable cover. The apparatus includes a replacement cover for the containment, a vacuum source, a fitting mounted in an aperture in the replacement cover and connected through a valve through a vacuum source, and a sprayer wand for spraying soapy liquid onto interior walls of the tank. Also provided is a method for detecting leaks in a storage tank or containment including the steps of emptying the tank of its contents, cleaning interior walls of the tank, spraying a soapy water liquid onto interior walls of the tank, reducing pressure within the tank, and examining the interior walls of the tank for bubbles.
Claims13
A kit for simultaneous real-time detecting leaks and their location in a containment-vessel of the type having a removable cover, said system comprising:
- a temporary replacement cover sized and shaped to fit the containment-vessel in place of the removable cover;
- a vacuum source for reducing pressure within an interior of the containment vessel,
- a fitting mounted to a first aperture in the temporary replacement cover and connected through a valve to the vacuum source;
- a sprayer wand configured for spraying a soapy liquid onto interior walls of the containment unit, the sprayer wand having a feed line connected through a second aperture in the temporary replacement cover;
- and
- a video camera configured for recording images of bubble formation on the interior walls of the containment-vessel and for transmitting said images to a location exterior to the containment vessel, whereupon a presence and location of a leak may simultaneously be determined, in real-time, from images taken by the video camera.
A method for simultaneous real-time detecting leaks and their location in a containment vessel, having a removable cover comprising:
- removing the removable cover;
- emptying the containment vessel of its contents;
- cleaning interior walls of the containment vessel;
- replacing the removable cover with a temporary replacement cover having a fitting mounted to a first aperture in the temporary replacement cover;
- spraying a soapy water liquid onto interior walls of the containment vessel using a sprayer wand having a feed line connected through a second aperture in the temporary replacement cover;
- reducing pressure within the containment vessel by drawing a vacuum through the fitting;
- using a video camera located within the containment vessel,
- to examine the interior walls of the containment vessel for bubbles;
- and
- transmitting images taken by the video camera to a location exterior to the containment vessel, whereupon a presence and location of a leak simultaneously may be determined in real-time, from images taken by the video camera, by a presence of bubbles on the interior walls of the containment vessel.
