Description
Technical field
The utility model relates to a kind of servicing unit of large coal powder boiler burner, specifically is a kind of Pulverized Coal Concentration device.
Background technology
The pulverized-coal fired boiler that is used for thermal power generation generally is provided with pulverized coal concentrator, pulverized coal concentrator generally has two kinds, a kind of is the vertical strong/weak pulverized coal concentrator, its bias pulverized coal is to arrange vertically, it is applicable to the concentration coal burner of arranged vertical up and down, another kind is the horizontal bias pulverized coal concentrator, and its bias pulverized coal is horizontal parallel arranged, and it is applicable to the concentration coal burner of horizontal parallel arranged.At present, the Pulverized Coal Concentration device that is used for the boiler vertical strong/weak coal burner of thermal power generation, usually adopt elbow type inertia inspissator, utilize pulverized coal particle different with the inertia of the air stream of pulverized coal conveying, and reaching the purpose that makes Pulverized Coal Concentration, the crooked blade in the coal nozzle body of the deep or light two-phase breeze airflow after concentrating is directed to the corresponding deep or light phase nozzle of coal nozzle respectively.The cocnentration factor of this elbow type inertia inspissator is little, and the guide vane manufacture difficulty in the coal nozzle body is big, and the accuracy of manufacture should not guarantee that it is comparatively serious to wear and tear.The flap type pulverized coal concentrator that is used for Horizontal Dense dilute Pulverized Coal Burners is 93209806.1 as the patent No., and name is called in the patent documentation of " louver pulverized coal concentrator ", has introduced a kind of device that utilizes blade and distributing damper to concentrate coal dust.Because it is the service object with the horizontal bias burner, air-flow in vertical direction CONCENTRATION DISTRIBUTION between deep or light two-phase coal dust has homogeneity, and the structure that shows as inspissator is only relevant with the applied coal of burner.This can not use on the vertical bias combustion device safely and effectively.Therefore need to propose a kind of vertical strong/weak pulverized coal concentrator that improves structure, be applicable to the vertical strong/weak coal burner better.
The utility model content
The purpose of this utility model is in order to solve the problems of the technologies described above, and proposes a kind of combined type vertical strong/weak Pulverized Coal Concentration device at the defective and the limitation of background technology, and this enrichment facility is rational in infrastructure, and concentrated effect is good, the efficient height, and security is good.
The purpose of this utility model is achieved through the following technical solutions: combined type vertical strong/weak Pulverized Coal Concentration device, be provided with housing, concentrate blade and split-flow baffles, it is characterized in that: be provided with light dense inspissator down and last dense light inspissator down, each inspissator is equipped with housing, be upper shell and lower house, the rear and front end of each housing is an opening, wherein after-opening is the import of breeze airflow before concentrating, open front is the outlet that concentrates the back breeze airflow, be provided with concentrated rows of blades in the upper shell, this rows of blades by the back import upper wall successively forward the outlet the middle and lower part oblique arrangement, each blade is low early and high after, and arrange the space, and the two ends, the left and right sides of blade are fixed on the housing, wherein first blade rear end closely is connected with the upper wall of housing, is provided with split-flow baffles in the front of final blage; Also be provided with concentrated rows of blades in the described lower house, this rows of blades by the back import lower wall successively forward the outlet the middle and upper part oblique arrangement, high back is low before each blade, arrange the space, the two ends, the left and right sides of blade are fixed on the housing, leave between the lower wall of wherein first blade rear end and housing at interval, be provided with split-flow baffles in the front of final blage.
Because the layout feature of pulverized coal channel elbow can make the coal dust and the air mass flow that enter inspissator housing upper area higher usually.At this particularity, adopt first blade and housing upper wall closing structure in the upper shell, seamlessly closely be connected between the upper wall of promptly first blade and upper shell.And lower house adopts the opening structure of first blade, leaves the gap between the lower wall of promptly first blade and housing.The structure of described upper shell is following dense type, and the structure of lower house is last dense type, and the last lower house of this utility model constitutes combined type vertical strong/weak pulverized coal concentrator, be used in combination up and down, and be a kind of Pulverized Coal Concentration device that is specially adapted for the vertical strong/weak coal burner.Have rational in infrastructure, easy to use, the thickening efficiency height, safety is specially adapted to the advantage of vertical strong/weak coal burner.
