Abstract
The invention relates to a connecting pipe for a pulverized coal burner of a magnesium metal reduction furnace. The connecting pipe comprises a flange 1, a connecting tube I 2, a connecting flange 3, an inner cone 4, a bolt 5 and a connecting tube II 6. The connecting pipe has the main advantage that pulverized coal is uniformly distributed in the connecting tube group from a distributor by the connecting pipe.
Description
Technical field
The present invention relates to a kind of tube connector of coal burner of metal magnesium reduction furnace.
Background technology
In prior art by Pulverized Coal Concentration device, utilize the effect of coal dust inertial separation to realize the air-coal separating of breeze airflow, in coal burner, form thick coal culm air-flow and thin powdered coal air-flow.But before penetrating after coal burner outlet, entering burning-out zone, do not separated completely between thin powdered coal air-flow and thick coal culm air-flow, thin powdered coal air-flow and thick coal culm air-flow are easy to again mix, and destroy air-coal separating effect, and then limited to NOx inhibitory action.How to realize the air-coal separating of breeze airflow better, thus the generation suppressing reduction furnace NOx is better the technical barrier that current those skilled in the art face.
summary of the invention:
The object of the invention is to for above-mentioned technical barrier, first object of the present invention is, provides a kind of tube connector that can improve the coal burner of the air-coal separating combustion efficiency of breeze airflow better, thus suppresses the generation of coal dust NOx better.For achieving the above object, the technical solution used in the present invention is: the tube connector that the present invention relates to a kind of tube connector of coal burner of metal magnesium reduction furnace, comprise flange 1, adapter I 2, adpting flange 3, inner cone 4, bolt 5, adapter II 6 composition, it is characterized in that the inner cone 4 of the tube connector of the tube connector of the coal burner of described a kind of metal magnesium reduction furnace is solid.Described flange 1 li is welded adapter I 2.Described adpting flange 3 side is welded with adapter I 2, and opposite side welds with adapter II 6.Described inner cone 4 is connected with adpting flange 3 by bolt 5, and bolt 5 is between adapter I 2 and adapter II 6.
advantage of the present invention is mainly reflected in:
Coal dust is assigned in adapter group by distributor by tube connector equably.
description of drawings 1 is a kind of schematic diagram of tube connector of coal burner of metal magnesium reduction furnace:
1-flange 2-adapter I 3-adpting flange 4-inner cone 5-bolt 6-adapter II.
detailed description of the invention illustrates embodiment 1:
tell about below in conjunction with Fig. 1a kind of tube connector of coal burner of metal magnesium reduction furnace
the course of work:
Tube connector comprises flange 1, adapter I 2, adpting flange 3, inner cone 4, bolt 5, adapter II 6 composition, it is characterized in that the inner cone 4 of the tube connector of the tube connector of the coal burner of described a kind of metal magnesium reduction furnace is solid.Described flange 1 li is welded adapter I 2.Described adpting flange 3 side is welded with adapter I 2, and opposite side welds with adapter II 6.Described inner cone 4 is connected with adpting flange 3 by bolt 5, and bolt 5 is between adapter I 2 and adapter II 6.Coal dust is assigned in adapter group by distributor by tube connector equably.
