Provided with some spinning disks, spinning disk is located at interior furnace shell afterbody, circumference uniform distribution.Spinning disk not only acts as support interior furnace shell and outer furnace shell
Effect, cooling wind is rotated into mixing chamber at an angle, strengthen mixed effect, improve cooling effectiveness, effectively reduction
The temperature of flue gas after burning.
The silicone hydride waste gas incinerating and purifying system that the present invention is provided, practical operation principle is：
The silicone hydride waste gas that is produced in silane enterprise production process introduces burner, and coal gas combustion-supporting is had by oneself with plant area, into burning
Burned the combustion chamber burnt in stove.Combustion-supporting coal tolerance ensures that silicone hydride waste gas burns completely.Burn the heat smoke produced and enter mixed
Room is closed, while entering mixing chamber through chuck layer and spinning disk using normal temperature air as cooling wind.Cool down wind simultaneously cool down interior furnace shell and
Outer furnace shell, instead of refractory material and insulation material, saves cost, increase operation flexibility ratio.Spinning disk makes cooling wind and combustion chamber
Heat smoke out is mixed in mixing chamber in eddy flow shape, strengthens mixed effect.Whole incinerator keeps micro-vacuum state, it is ensured that
Gas No leakage, it is safe and reliable.Flue gas after cooling enters multi-tube dust cleaner, removes large-size particles, enters back into bag-type dust
Device removes remaining solid particle, and efficiency of dust collection is improved while reducing the abrasion to upstream device.After two-stage dust removal process
Flue gas up to standard eventually enters into smoke stack emission.If running into emergency situations, promptly blowing out and it can be purged with indifferent gas.
Beneficial effect：Compared to the prior art there is advantages below in the silicone hydride waste gas incinerating and purifying system that the present invention is provided：
(1) silicone hydride waste gas that the present invention is provided is burned and cleaning system, to silane gas fluctuation of concentration wide adaptation range, is used
