Abstract
The utility model provides a dust removing and fire-resistant hot air furnace. A furnace body is divided into a combustion chamber and a dust removing chamber by a partition wall. The top part of the dust removing chamber is provided with a furnace cover with a dust removing guide pipe, and the lower part of the dust removing chamber is provided with an ash cleaning door. The partition wall is provided with an inner air channel which can be used for communicating the two chambers and is tangent with the dust removing guide pipe. The hot air furnace has the double functions of providing and purifying heat source, can prevent coal ash or spark form entering a drying device to cause dust burning or explosion, and can ensure the safe operation of the drying device and the quality of dried materials.
Description
The utility model relates to a kind of hot-blast stove, particularly relates to a kind of dedusting fire insulation hot-blast stove.
Present widely used hot-blast stove is not with dust removal installation, and the burned coal of air that blasts in the stove is heated into hot-air, for pneumatic conveying dryer provides hot air source.Because air velocity is fast, can carry coal ash secretly or Mars enters drying equipment, cause dust combustion or blast, simultaneously the also influence quality of material that is dried.Re-use after for addressing this problem the hot-air that hot-blast stove can be sent, but need increase equipment, complex process with special cleaner dedusting.
The purpose of this utility model is to provide a kind of dedusting fire insulation hot-blast stove that thermal source is provided and purifies the thermal source dual-use function that has.
The utility model dedusting fire insulation hot-blast stove comprises body of heater, and partition wall is divided into combustion chamber and dirt pocket with body of heater, and top of combustion chamber has the bell of band chimney, and the bottom is provided with grate, fire door, clean-out door and blast channel; The dirt pocket top is provided with the bell of band dust removal pipe, and shoot door is arranged at the bottom; Partition wall is provided with two Room is communicated with, and the interior air channel tangent with dust removal pipe.Its operation principle is, coal enters the combustion chamber from fire door, blast air-breathing by blast channel, produce a large amount of hot-airs and enter dirt pocket through interior air channel, because interior air channel and dust removal pipe are tangent, the hot-air rotational flow, because of centrifugal action make ash content of coal from and fall to bottom the dirt pocket along the dust removal pipe outer wall, hot-air after the purification is from dust removal pipe outflow suitable for reading, and air feed fluidized drying equipment is used.The coal ash that settles down is removed from shoot door.
The advantage of the utility model dedusting fire insulation hot-blast stove is simple in structure, the thermal source of providing is provided, purify the dual-use function of thermal source, avoid coal ash and Mars to enter drying equipment and cause dust combustion or blast, guarantee the safe operation of drying equipment and the quality of the material that is dried.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
