Abstract
The invention relates to a pulverized coal distributor of a pulverized coal burner of a magnesium metal reduction furnace. The pulverized coal distributor comprises a flange 1, a large-volume taper pipe 2, a flange 3 and a bolt 4. The pulverized coal distributor has the advantages that due to the fact that the pulverized coal distributor is designed to be a large conical cavity, even and orderly distribution of pulverized coal is facilitated, reparability and long-term and continuous use are realized, production cost is reduced effectively, and the service life of the pulverized coal distributor is prolonged.
Description
Technical field
The present invention relates to a kind of pulverized coal distributor of coal burner of metal magnesium reduction furnace.
Background technology
Pulverized coal distributor is the special equipment of metal magnesium reduction furnace each air port mean allocation coal dust in stove, pulverized coal distributor is reduction furnace coal injection system accessory, belong to special-shaped structural part equipment, complex manufacturing process, manufacture craft requires higher, adopt the manufacture of carbon steel structure part, processing precise, geometric accuracy is high.Cone cavity structure is simple, volume is little, lightweight, maintenance is easy.Chamber body adopts alienation wearing layer, and inner chamber makes radian will consider that stream condition enters each arm with what make coal dust uniform and stable, and arm and body joint adopt hardfacing.Along with the progressively raising of the raising reduction furnace coal ejection ratio of production capacity, the ability to work of coal powder injection distributor receives unprecedented test.
summary of the invention:
The object of the invention is to for above-mentioned technical barrier, the object of the present invention is to provide the pulverized coal distributor that a kind of coal powder injection ability is strong.For achieving the above object, the technical solution used in the present invention is: the pulverized coal distributor that the present invention relates to a kind of coal burner of metal magnesium reduction furnace, comprise flange 1, greatly volume Taper Pipe 2, flange 3, bolt 4 to form, the tapering of the large volume Taper Pipe 2 of the pulverized coal distributor of the coal burner of described a kind of metal magnesium reduction furnace is 1:15.
advantage of the present invention is mainly reflected in:
Pulverized coal distributor is designed to bevel-type major lumen, be conducive to the uniform sequential distribution of scattering of coal dust, both had and can repair, can the feature of sustainable utilization for a long time, effectively save production cost, coal dust distribution cone dish is clipped between seat, lid, with bolts, be convenient to wear-resisting position, inner chamber tapering make regular check on, wear and tear or plugging time can dismounting, reparation, replacing, extend the service life of pulverized coal distributor.

1-flange 2-large volume Taper Pipe 3-flange 4-bolt.
detailed description of the invention illustrates embodiment 1:
tell about below in conjunction with Fig. 1a kind of pulverized coal distributor of coal burner of metal magnesium reduction furnace
the course of work:
The present invention relates to a kind of pulverized coal distributor of coal burner of metal magnesium reduction furnace, comprise flange 1, greatly volume Taper Pipe 2, flange 3, bolt 4 to form, the tapering of the large volume Taper Pipe 2 of the pulverized coal distributor of the coal burner of described a kind of metal magnesium reduction furnace is 1:15.Coal dust enters distributor from pipeline, and the sudden change of inner chamber cavity volume strengthens, and powder gas is from being mutated into low speed at a high speed, and coal dust is in suspension, in the inner chamber of pulverized coal distributor, fill the air distribution, then evenly flows out in each coal dust arm.Volume is little, compact conformation, and inner chamber design is unique, compared with traditional coal powder injection distributor, little especially, the stifled inner chamber of resistance loss and outlet stool when coal dust passes through, smooth and easy in coal dust course of conveying, gas is little, good stability, distributed uniform degree is high, distributes error≤4%.
Claims (1)
