FIELD: oil and gas industry.
SUBSTANCE: device for periodic cleaning of coke furnace doors (2) comprises devices for generating a cleaning jet (4) with solid particles to remove sediments. A unit (3) which generates the cleaning jet (4) with the help of a nozzle (5) when its position changes can be moved by means of a mechanism (7) parallel to the surface of the door being cleaned in mutually perpendicular directions and is configured to form a fan-shaped expansion of the cleaning jet (4) in one of said directions. A programmable device (9) is connected to the moving mechanism (7) and to an optical sensor (8) configured to register the purification achieved. The cleaning jet (4) can be formed by solid particles containing dry ice, and transport gas.
EFFECT: invention makes it possible to adjust parameters of the cleaning jet depending on the contamination degree, efficiently perform cleaning in automatic mode, and prevent spreading of resin-containing particles into the environment.
