Embodiment Construction

[0069] [69] cf. figure 1 , the shown incinerator is actually a traditional MSW incinerator added with an injection system in accordance with the present invention.

[0070] [70] A grab bucket 1 fixed to an overhead crane 2 can grab household waste into a storage tank (not shown) and dump (a) them into a feed hopper 3 . These household wastes arrive at (b) an incineration bed 4 .

[0071] [71] In this conventional example, the incineration bed 4 consists of three successive zones (or steps), each zone formed by rollers:

[0072] [72] - a drying zone 5 for domestic waste to facilitate their subsequent combustion;

[0073] [73] - a combustion zone 6; and

[0074] [74] - An end zone 7.

[0075] [75] After the domestic waste passes through the incineration bed, the slag 13 is obtained, and the slag 13 is collected in a bucket 9 (or other storage device) through a discharge hopper 8 for discharge.

[0076] [76] Further discharge hoppers 10, 11, 12 may also be provided below the...

Abstract

The invention relates to an injection system for injecting pasty, semi-pasty or liquid waste into a furnace chamber comprising at least one hearth (4), said system comprising: an injection body (25) having a waste supply inlet (23) and a refuse supply chamber (28); an injection device of a pressurized gaseous fluid; at least one spray head (33) which comminutes said refuse on said hearth; said injector and / or Or the nozzle is directed to the orientation device of the hearth; it is characterized in that the injection device of the pressurized gaseous fluid comprises at least one pressurized gaseous fluid supply chamber (26), and the pressurized gaseous fluid supply chamber (26) is basically It is arranged around the garbage supply chamber (28); and the spray head (33) has the garbage injection flow channel (33a) at a substantially central position, and has a plurality of peripheral flow channels (27), and the peripheral flow channel (27) connected to said pressurized gaseous fluid supply chamber (26) located around said waste injection flow channel (33a), said peripheral flow channel (27) relative to the longitudinal axis (A ) is inclined in a convergent manner, and the pressurized gaseous fluid injected by the peripheral flow channel (27) can break up the garbage distributed by the garbage injection flow channel (33a) and project them to the furnace of the incinerator on the bed (4).

Description

technical field [0001] [01] The present invention relates to the field of incineration of waste in incinerators. [0002] [02] More precisely, the present invention relates to the incineration of pasty, semi-pasty or liquid waste, either alone or together with other types of waste. Background technique [0003] [03] The invention finds particular application in incinerators for the incineration of residues from biological purification of water or residues from industrial processes, and particularly, but not exclusively, for these residues in combination with domestic waste (or other municipal Garbage or industrial waste) mixed incinerators are used. [0004] [04] The invention also finds application in the pulverization of slurry in cement furnaces. [0005] [05] The invention also finds application in the co-incineration of manure with domestic waste, thus finding a discharge system for excess manure produced in certain regions. [0006] [06] The invention can be used in...
