Title:
PROCESS SCOPE
Document Type and Number:
WIPO Patent Application WO/2019/113716
Kind Code:
A3
Abstract:
The invention relates to a device (1), especially a process scope, for the in-line or in-situ observation, monitoring, closed-loop and open-loop control of chemical and physical processes in the interior of explosion-proof containers and reactors, especially in large-scale industrial systems, during operation and without interruption of the production and/or development and research process. Said device (1) comprises an observation tube (3) having a tube tip (3'), an electro-optic or spectroscopic camera (6), a shock-proof housing (2) with an electronic protection circuit (5) and a lighting device (4), and image processing electronics (19). The tube tip (3') does not have any ignition sources and is suitable for use in danger zones 0/20 or 1/21 of an explosion-proof area. The housing (2) is explosion-proof and suitable for use in danger zones 1/21 or 2/22 of an explosion-proof area. The power supply unit (17) and the data acquisition, data analysis and data recording system (19) are provided for use in danger zone NH of an explosion-proof area. Optical waveguides, especially optical cables (21, 23) are provided for transferring light from the lighting device (4) to the tube tip (3') and for the image transfer from the tube tip (3') to the electro-optic or spectroscopic camera (6). A single- mode or multi-mode glass fiber data cable (18) is provided for the transmission of image data from the electro-optic or spectroscopic camera (6) to the data acquisition, data analysis and data recording system (19). By arranging the lighting and monitoring front windows laterally in the tube tip (3'), it is possible to carry out, for example, parallax distance measurements within the reaction vessel.
