Abstract
The invention discloses a coal powder dense and thin separation device. At least two separation blocks are arranged on the inner wall of a primary wind pipe and/or the outer wall of a center wind pipe. The coal powder dense and thin separation device is simple in structure, fast in installation, convenient for disassembly and low in cost, and simplifies the structure and the disassembly process of a traditional coal powder dense and thin separation device.
Description
Technical field
The present invention relates to a kind of coal powder light-dark separation device, particularly relate to a kind of light-dark separation device for industrial coal powder boiler.
Background technology
The use that Industrial Boiler is always up China important in recent decades can equipment.Based on the energy resource structure of China's " rich coal, gas oil-poor, few ", in industrial boilers in China, 85% is coal-burned industrial boiler.At present, having most of coal poor for the ature of coal such as soft coal, meager coal, easy slagging scorification when burning in stove of this fuel in domestic boiler combustion fuel, pollutant discharge amount is big, and the operation of pulverized-coal fired boiler is had very big adverse effect.In order to reach the purposes such as steady combustion, low NOX emission, the bonding of minimizing slag, prolonged boiler service life, the extensive use in boiler combustion of pulverized coal bias combustion technology.Currently, the main method that pulverized coal bias combustion technology adopts has following several: bend pipe inertial separation method, shutter separation method, concentration ring method and pipe convex block method etc..
Summary of the invention
It is an object of the invention 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.
Presently disclosed a kind of coal powder light-dark separation device, is provided with at least two separation block on the inwall of described primary air piping and/or on the outer wall of central air hose.
Preferably, described separation block is triangle vertebral body.
The ratio L1/L2 of the spacing L1 of described adjacent two triangle vertebral bodys and triangle vertebral body bottom side length L2 is 0.1 ~ 1.2, the ratio L3/L2 of triangle vertebral body hypotenuse projected length L3 and L1 is 0.2 ~ 0.8, and the ratio L2/R of triangle vertebral body bottom side length L2 and First air pipe radius R is 0.68 ~ 1.43.
Coal powder light-dark separation device of the present invention, owing to have employed as above technical scheme, its simple in construction, quick for installation, convenient disassembly, with low cost, simplify 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 present invention will be further described.
Embodiment 1
Installation site according to segregation apparatus is different, described coal powder light-dark separation device can be divided into single wall to arrange 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, is provided with four on the inwall of described primary air piping 1 and on the outer wall of central air hose 2 and separates block 3.Described separation block is triangle vertebral body.The ratio L1/L2 of the spacing L1 of described adjacent two triangle vertebral bodys and triangle vertebral body bottom side length L2 is 0.1, and the ratio L3/L2 of triangle vertebral body hypotenuse projected length L3 and L1 is 0.2, and the ratio L2/R of triangle vertebral body bottom side length L2 and First air pipe radius R is 0.68.Preferably, described triangle vertebral body adopts abrasion-proof stainless steel material, and the light-dark separation device using as above technical scheme is high temperature resistant, anticorrosion.
Embodiment 2
Consult Fig. 3, difference from Example 1 is in that, the present embodiment adopts single wall to arrange, described separation block is provided entirely on the inwall of primary air piping 1, the ratio L1/L2 of the spacing L1 of described adjacent two triangle vertebral bodys and triangle vertebral body bottom side length L2 is 0.6, the ratio L3/L2 of triangle vertebral body hypotenuse projected length L3 and L1 is 0.5, and the ratio L2/R of triangle vertebral body bottom side length L2 and First air pipe radius R is 1.
Embodiment 3
Consult Fig. 4, difference from Example 1 is in that, the present embodiment adopts single wall to arrange, described separation block is provided entirely on the outer wall of central air hose 2, the ratio L1/L2 of the spacing L1 of described adjacent two triangle vertebral bodys and triangle vertebral body bottom side length L2 is 1.2, the ratio L3/L2 of triangle vertebral body hypotenuse projected length L3 and L1 is 0.8, and the ratio L2/R of triangle vertebral body bottom side length L2 and First air pipe radius R is 1.43.
Coal powder light-dark separation device of the present invention, its simple in construction, quick for installation, convenient disassembly, with low cost, simplifying structure and the dismounting process of current coal powder light-dark separation device, described separation block adopts abrasion-proof stainless steel material, the industrial coal powder boiler using as above light-dark separation device is high temperature resistant, anticorrosion, Anti-slagging, low NOXDischarge.
