PROBE AND SYSTEM FOR REMOVAL OF GASES FROM PROCESS EQUIPMENT Russian patent published in 2010 - IPC G01N1/22 

FIELD: mechanics.

SUBSTANCE: system includes probe for removal of the above gaseous fluid medium, which includes the first tubular element which can be positioned inside process equipment; at that, the above first tubular element has on one of its ends the gas suction opening and restricts inner cavity, and the second tubular element passing in the cavity of the first tubular element; at that, the above second tubular element is controlled for injection of the above gaseous fluid medium to inner area of cavity towards the above suction hole of the first tubular element and from there again to process equipment. System includes suction devices for suction of gaseous fluid medium from process equipment through the cavity of the above first tubular element of the probe. In the system there made are removal devices connected to the above suction devices for removal of fraction of the above gaseous fluid medium. At that, the above removal devices are connected in addition to analyser for analysis of the above gaseous fluid medium. System also includes the devices for repeated injection, which are intended for repeated injection of the above gaseous fluid medium to process equipment through the second tubular element. The above suction devices and the above devices for repeated injection use compressor device; at that, the above compressor device has suction side and delivery side. At that, the above first tubular element is hydraulically connected to control valve device which is controlled for selective hydraulic connection of the above first tubular element to the above suction side or delivery side of compressor device. In the system the above second tubular element is located in hydrodynamic connection to delivery side of the above compressor device through the capacity; at that, the above second tubular element is throttled so that the flow of the above gaseous fluid medium passing through it can be accelerated, and at the same time, the possibility of accumulation of the above gaseous fluid medium higher up process chain can be provided in the above capacity. At such location in the system there allowed is suction condition in which gaseous fluid medium is taken through the above first tubular element and is partially injected again through the above second tubular element and partially accumulated with the above capacity. At that, the above gaseous fluid medium is released with the above capacity through the above first tubular element by means of activation of the above control valve device.

EFFECT: decreasing blockage of the probe and providing continuous use of the system, reducing the necessity for frequent maintenance.
