Abstract
A kind of coal powder light-dark separation device disclosed in the utility model, comprises primary air piping and central air hose, on the inwall of described primary air piping and/or on the outer wall of central air hose, is provided with at least two explants.Coal powder light-dark separation device described in the utility model, its structure is simple, quick for installation, and convenient disassembly is with low cost, simplifies structure and the dismounting process of current coal powder light-dark separation device.
Description
Technical field
The utility model relates to a kind of coal powder light-dark separation device, particularly relates to a kind of light-dark separation device for industrial coal powder boiler.
Background technology
Industrial Boiler be in recent decades always China important with can equipment.Based on the energy resource structure of China's " rich coal, oil-poor, weak breath ", in industrial boilers in China, 85% is coal-burned industrial boiler.At present, have most of coal poor for the ature of coal such as soft coal, meager coal in domestic boiler combustion fuel, the easy slagging scorification when stove combustion of this fuel, pollutant discharge amount is large, has very large adverse effect to the operation of pulverized-coal fired boiler.In order to reach steady combustion, low NO
xthe objects such as discharge, the bonding reducing slag, prolonged boiler service life, the extensive use in boiler combustion of pulverized coal bias combustion technology.Current, the main method that pulverized coal bias combustion technology adopts has following several: bend pipe inertial separation method, shutter separation method, concentrated ring method and pipe convex block method etc.
Summary of the invention
The purpose of this utility model is to provide a kind of coal powder light-dark separation device, to simplify structure and the dismounting process of current coal powder light-dark separation device.
A kind of coal powder light-dark separation device disclosed in the utility model, comprises primary air piping and central air hose, on the inwall of described primary air piping and/or on the outer wall of central air hose, is provided with at least two explants.
Preferably, described explant is triangular pyramids.
The spacing L1 of described adjacent two triangle centrums and the ratio L1/ L2 of triangle centrum bottom side length L2 is 0.1 ~ 1.2, the ratio L3/L2 of triangle centrum hypotenuse projected length L3 and L1 is 0.2 ~ 0.8, and the ratio L2/R of triangle centrum bottom side length L2 and First air pipeline radius R is 0.68 ~ 1.43.
Coal powder light-dark separation device described in the utility model, owing to have employed as above technical scheme, its structure is simple, quick for installation, and convenient disassembly is with low cost, simplifies structure and the dismounting process of current coal powder light-dark separation device.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described further.
Embodiment 1
Different according to the installation site of separator, single wall can be divided into arrange for described coal powder light-dark separation device and double-walled arranges two kinds, see also Fig. 1 and Fig. 2, the present embodiment adopts double-walled to arrange, a kind of coal powder light-dark separation device, comprise primary air piping and central air hose, on the inwall of described primary air piping 1 and on the outer wall of central air hose 2, be provided with four explants 3.Described explant is triangular pyramids.The spacing L2 of described adjacent two triangular pyramids and the ratio L2/ L1 of triangular pyramids bottom side length L1 is 0.1, and the ratio L3/L1 of triangular pyramids hypotenuse projected length L3 and L1 is 0.2, and the ratio L1/R of triangular pyramids bottom side length L1 and First air pipeline radius R is 0.68.Preferably, described triangular pyramids adopts abrasion-proof stainless steel material, uses that the light-dark separation device of as above technical scheme is high temperature resistant, anticorrosion.
Embodiment 2
Consult Fig. 3, difference from Example 1 is, the present embodiment adopts single wall to arrange, described explant is all arranged on the inwall of primary air piping 1, the spacing L2 of described adjacent two triangular pyramids and the ratio L2/ L1 of triangular pyramids bottom side length L1 is 0.6, the ratio L3/L1 of triangular pyramids hypotenuse projected length L3 and L1 is 0.5, and the ratio L1/R of triangular pyramids bottom side length L1 and First air pipeline radius R is 1.
Embodiment 3
Consult Fig. 4, difference from Example 1 is, the present embodiment adopts single wall to arrange, described explant is all arranged on the outer wall of central air hose 2, the spacing L2 of described adjacent two triangular pyramids and the ratio L2/ L1 of triangular pyramids bottom side length L1 is 1.2, the ratio L3/L1 of triangular pyramids hypotenuse projected length L3 and L1 is 0.8, and the ratio L1/R of triangular pyramids bottom side length L1 and First air pipeline radius R is 1.43.
coal powder light-dark separation device described in the utility model, its structure is simple, quick for installation, convenient disassembly, with low cost, simplify structure and the dismounting process of current coal powder light-dark separation device, described explant adopts abrasion-proof stainless steel material, use that the industrial coal powder boiler of as above light-dark separation device is high temperature resistant, anticorrosion, Anti-slagging, low NO
xdischarge.
