Abstract
The utility model relates to an air distributing device of a pulverized coal gasification furnace, and belongs to the field of coal gas generation equipment. The air distributing device is characterized by comprising a tube nest, air tubes, air caps and cap holes, the tube nest is circular, a preformed hole for a slagging pipeline is arranged in the middle of the tube nest, the air tubes are uniformly arranged on the tube nest, the air caps are arranged on tops of the air tubes, and the cap holes are arranged on the air caps. The air distributing device has the advantages that the air tubes are distributed uniformly, so that air can be distributed uniformly; and high-temperature-resistant refractory material layers are arranged among the air tubes, so that the service life of each air tube running at a high temperature for a long time is guaranteed, the equipment operation rate and the yield are increased, production cost is virtually reduced, and market competitiveness is improved.
Description
Technical field
The utility model relates to a kind of air-distributing device of powder coal gasification furnace, belongs to the coal gas generating apparatus field.
Background technology
At present, in normal suitability for industrialized production and resident's thereof daily life, all to use coal gasification apparatus, change coal into coal gas, and in this process, all need to use pulverized coal gasification furnace, and match also need to be provided with the coal gasification air compartment, and must be provided with air-distributing device in the coal dust gasification air compartment, yet existing air-distributing device, design is also unreasonable, so that when air-distributing device cloth wind and inhomogeneous, simultaneously because under hot conditions, the work-ing life of equipment is not high, replacement frequency is too fast, causes operation rate not high, incurs loss through delay and produces.
Summary of the invention
According to the deficiencies in the prior art, the technical problems to be solved in the utility model is: a kind of air-distributing device of powder coal gasification furnace is provided, and cloth wind is even, long service life.
The technical scheme that its technical problem that solves the utility model adopts is: the air-distributing device that a kind of powder coal gasification furnace is provided, it is characterized in that comprising: card, airduct, blast cap and cap hole, card is annular, the middle part is provided with deslagging pipeline pre-opened hole, evenly be provided with airduct on the card, the airduct top is provided with blast cap, is provided with the cap hole on the blast cap.
Described cap hole and horizontal direction are 15 ° of downward-sloping angles.
The described airduct that arranges at card, the airduct height successively decreases successively from outside to inside.
Be provided with high temperature resistant refractory masses between the described airduct.
The beneficial effects of the utility model are: it is more even that airduct distributes in such being arranged so that, just meeting is so that cloth wind is more even, be provided with high temperature resistant refractory masses between airduct and the airduct simultaneously, guaranteed like this its airduct work-ing life under the long term high temperature operation, improved operation rate, increase output, virtually reduced production cost, improved the market competitiveness.
