Abstract
A grid distributor of coal power belongs to the equipment of inputting pipe of coal power in furnace. The distributor comprises an upper shell, a lower shell, an upper grid body and a lower grid body. The upper grid body and the lower grid body are arranged inside the upper shell and the lower shell. The coal power burns completely in a burner though twice uniform subdivision when the coal power with high speed is blown into the lower shell. The coal power can be fully fed into every corner of the boiler burner because of four outlet arranged on the distributor of coal power, the accident of water wall tube explosion can be avoided, the operation is safe and reliable, and energy saving is obvious.
Description
The utility model belongs to the equipment on the input boiler furnace pulverized coal channel, makes the coal dust that enters burner hearth reach uniform distribution.
In boiler combustion system, when the high speed coal dust is blown into boiler-burner,,, wasted the energy so coal dust can not smooth combustion at burner because coal divides not by uniform subdivision.Also eccentricity of fire can occur simultaneously, when serious the water-cooling wall pipe explosion accident can take place.
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of grating type pulverized coal distributor of designing, make the coal dust of sending into burner obtain uniform subdivision twice, save the energy, also coal dust has been delivered to equably the every nook and cranny of burner simultaneously, avoided the generation of water-cooling wall pipe explosion accident.
The version of accompanying drawing 1, expression grating type pulverized coal distributor, the left side is a front view, the right is a left view.
Accompanying drawing 1, in numeral as follows:
1, upper shell 2, upward grid body 3, hanger 4, lower house 5, interior lining panel 6, Under The Grille body 7, adapter
The principle explanation:
This product is mainly by upper and lower casing, upper and lower grid body, interior lining panel, compositions such as adapter.Its operation principle is: when the high speed coal dust is blown into lower house, through n dividing plate, be divided into two mode with one and evenly be divided into 2 affluent-dividings.2m dividing plate in last grid body is divided into 4 even sprouts again.Make the coal dust that enters distributor obtain twice segmentation.Simultaneously, the grid body is inner evenly distributed with some blocks of lattice plates with equidistant spacer, has guaranteed the depth of parallelism of lattice plates thus, thereby has reduced pressure drop, makes coal dust obtain fully stable burning in burner.Again because of distributor has four outlets, so coal dust can be sent into the every nook and cranny fully.Thereby avoid causing the generation of water-cooling wall pipe explosion accident because of the serious deflection of furnace flame.
Claims (2)
1, grating type pulverized coal distributor.Comprise upper and lower casing and upper and lower grid body.It is characterized in that: upper and lower grid body is placed in the upper and lower casing.
2, pulverized coal distributor according to claim 1 is characterized in that: with equidistant spacer that some dividing plates are evenly distributed, and make the coal dust that blows into evenly be divided into 2 tributaries with the form that is divided into two.
