Apparatus to eliminate carbon deposits on solid objects

摘要

Heating (101a) and treatment (101b) zones are in the same enclosure (100), which includes a vibrating element with a flat base (101) designed to support the objects, allow the treatment fluid to diffuse around them and transmit vibrations to transport them. A cooling zone (101c) is in the enclosure downstream of the treatment zone and external means of heating (115, 116) are provided There is an inlet (102) for the objects to be treated, a heating zone (101a) with a feed (104) and an outlet for the heating gas, a treatment zone (101b) for oxidation and/or gasification of the objects with a feed (105) and an outlet (108) for the gasification fluids and an outlet (118) for the objects. A pipe (111) between the heating gas outlet and the cooling gas inlet contains a compressor (112) and a valve (108). The means of heating comprises a burner (116) attached to a combustion chamber (115) with the burner inlet connected to an outlet from the cooling zone and the combustion chamber outlet connected to a heating zone inlet. A bypass pipe (114) round the means of heating carries the gases which do not need to be reheated. The inlet for the gasification fluid includes a multipoint distributor (106) and its outlet has a multipoint collector (108) which has a single outlet connected to the inlet to a heat exchanger (109) or heater. The device includes means of isolating (103) the atmosphere between the heating zone and the treatment zone and between the treatment zone and the cooling zone. The treatment zone contains several separators. The vibrating element is a trough containing helical flanges, with a vibrator fixed to its inside diameter. The different gas feeds are through perforated tubes on the flat base of the trough. The base of the trough is made of gas feed caissons and the bottom surface of the trough is porous or perforated.
