Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details:
A dust-settling compartment for biomass thermal wind furnace, as shown in Figure 2, comprises the heat smoke entrance 8 being positioned at left side and the heat smoke outlet 9 being positioned at right side.Collecting plate 10 is set in the middle part of dust-settling compartment.Collecting plate 10 is ganoid metallic plate, and its tail end is welded in the inner left wall of dust-settling compartment; The plate of collecting plate 10 inclines towards dust-settling compartment bottom direction is micro-, and the angle of plate face and dust-settling compartment base plate is 15 ° ~ 30 ° acute angles; Collecting plate 10 front end bends downwards, and the angle of kink and dust-settling compartment base plate is 45 ° ~ 60 ° acute angles; Gap is formed between the right side inwall of kink front end and dust-settling compartment.Dust-settling compartment is divided into decanting zone and Chu Chen district two parts by collecting plate 10.After heat smoke enters dust-settling compartment, slack-off along with gas flow rate, the flue dust in heat smoke is slowly deposited on collecting plate 10, and then slowly landing under gravity, falls into Chu Chenqu by gap.
