Abstract

The invention relates to a wind distribution device facilitating discharging of big particle matter and a multi-flow circulating fluidized bed boiler. A horizontal wind distribution plate (28) of the wind distribution device is arranged horizontally. An inclined wind distribution plate (27) inclines downwards from one edge of the horizontal wind distribution plate (28), is in butt joint with the horizontal wind distribution plate (28) and then is arranged in the middle of a hearth. Other edges of the horizontal wind distribution plate (28) and other edges of the inclined wind distribution plate (27) are fixed to the inner ring of the hearth. A plurality of second wind caps (26) are arranged on the horizontal wind distribution plate (28). A plurality of first wind caps (25) capable of directionally outputting wind are arranged on the inclined wind distribution plate (27). A first wind chamber (23) supplies wind to the inclined wind distribution plate (27). A second wind chamber (24) supplies wind to the horizontal wind distribution plate (28). Slag dropping pipes (22) are arranged on the same side of the inclined wind distribution plate (27) and located in the lowest position of an inclined section. The wind distribution device can smoothly discharge the big particle matter disturbing uniform outlet air of the wind distribution plates, and accordingly it can be guaranteed that materials in the hearth are fluidized continuously and uniformly.

Description

Technical field [0001] The invention relates to the field of garbage and industrial waste treatment, in particular to an air distribution device and a multi-process circulating fluidized bed boiler that are beneficial to discharging large particles. Background technique [0002] In the process of incineration of garbage and industrial waste in a circulating fluidized bed, continuous and uniform fluidization of the materials in the furnace is the key to ensure that the garbage and industrial waste are successfully processed. [0003] The current circulating fluidized bed boiler structure figure 1 with figure 2 As shown, it includes: a furnace wall 6, a feeding pipe that feeds through the furnace wall 1, an air distribution plate 5 horizontally arranged in the furnace chamber wrapped by the furnace wall 6, an air chamber 4 and a row arranged at the bottom of the air distribution plate 5 Slag pipe 3, a number of wind caps 2 staggered arranged on the air distribution plate 5. [0004] ...
