Abstract
The utility model provides a fluidization orifice plate, which comprises a fluidization orifice plate body. The fluidization orifice plate body is provided with a plurality of ventilation holes which are in equilateral-diamond distribution. The ventilation holes in equilateral-diamond distribution have reasonable arrangement, can guarantee waste gas flow passing through the fluidization orifice plate to be uniformly distributed, and increase heat exchanging efficiency between the waste gas and coal materials, thereby increasing efficiency of adjusting coal material moisture. Periphery of the orifice plate is provided with folded edges, and pads and pressing boards are mounted on the folded edges, thereby simplifying the procedure of mounting the fluidization orifice plate onto a fixing board of a fluidization bed, increasing mounting efficiency and reducing working intensity of mounting.
Description
Technical field
The utility model relates to a kind of fluidisation orifice plate.
Background technology
The coal humidifying technology is to utilize the coke oven flue waste gas residual heat, and coking coal is carried out the adjusting of moisture, and simultaneously coal charge is advanced the technology of classification, can realize reducing the purpose of the lifting of coke oven energy consumption, enhancement of environment and coke quality.The fluidisation orifice plate is installed on the inside of fluid unit in the damping system, its major function is that the coal charge on the fluidisation orifice plate is formed " fluidisation " state, make and contain the coal charge of big moisture and come the coke oven exhaust gas of self-fluidized type orifice plate bottom fully to carry out heat exchange, make and reach the purpose of regulating coal charge moisture by the moisture of taking away coal charge that coke oven exhaust gas can be relatively large.But existing fluidisation orifice plate is deposited the passage irrational distribution of offering thereon, the problem that the air-flow by the fluidisation orifice plate is evenly distributed.
Summary of the invention
The purpose of this utility model has provided a kind of fluidisation orifice plate, and its passage is arranged rationally, can guarantee evenly to pass through the fluidisation orifice plate by fluidisation orifice plate bottom waste gas, can solve the problem that prior art exists.
The purpose of this utility model is achieved through the following technical solutions: the fluidisation orifice plate, comprise fluidisation orifice plate main body, and offer several passages on the fluidisation orifice plate main body, passage is equilateral rhombus and distributes.
For further realizing the purpose of this utility model, can also realize by the following technical solutions: the flanging of downward bending is set around the fluidisation orifice plate main body, and the inside and outside both sides of flanging are installed pressing plate and backing plate respectively, offer screw on the backing plate, construction bolt on the pressing plate, bolt is threaded with screw.Between backing plate and the flanging pad is installed.Chamfering is set on the backing plate.Spacing H1 between adjacent two passages is 10mm.The diameter of passage is 3mm.
Good effect of the present utility model is: its passage is equilateral rhombus and distributes, and arranges rationally, can guarantee evenly to distribute by the off-gas flows of fluidisation orifice plate, improves the heat exchanger effectiveness of waste gas and coal charge, thereby improves the efficient of regulating coal charge moisture; Around it flanging is set, pad and pressing plate are installed on the flanging, can simplify that the fluidisation orifice plate is installed on program on the fixed head of fluid bed, improve installation effectiveness, reduce the labour intensity of installing.
Description of drawings
Fig. 1 is that fluidisation orifice plate described in the utility model is installed on the structural representation on the fluid bed fixed head; Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1; Fig. 3 is the local structure for amplifying schematic diagram of the I of Fig. 2; Fig. 4 is the local structure for amplifying schematic diagram of the II of Fig. 1; Fig. 5 is the B-B sectional structure schematic diagram of Fig. 1.
Number in the figure: 1 pressing plate, 2 pads, 3 bolts, 4 fluidisation orifice plate main bodys, 5 backing plates, 6 passages, 7 chamferings, 8 flangings, 9 screws, 10 fluid bed fixed heads.
The specific embodiment
Fluidisation orifice plate described in the utility model comprises fluidisation orifice plate main body 4, as shown in Figure 4, offers several passages 6 on the fluidisation orifice plate main body 4, and passage 6 is equilateral rhombus and distributes.During use, waste gas, is risen to fluidisation orifice plate main body 4 tops and carries out heat exchange with coal charge after passage 6 evenly distributes by the bottom of fluidisation orifice plate main body 4.
For convenient the fluidisation orifice plate is installed on the fluid bed fixed head 10, as Fig. 3 and shown in Figure 5, the flanging 8 of downward bending is set around the fluidisation orifice plate main body 4, the inside and outside both sides of flanging 8 are installed pressing plate 1 and backing plate 5 respectively, offer screw 9 on the backing plate 5, construction bolt 3 on the pressing plate 1, and bolt 3 is threaded with screw 9, and promptly pressing plate 1 and backing plate 5 are mounted on the both sides of flanging 8 by bolt 3.During installation, earlier backing plate 5 is welded on the fluid bed fixed head 10, utilizes pressing plate 1 and bolt 3 that fluidisation orifice plate main body 4 and fluid bed fixed head 10 are connected and fixed then.
For reducing the relative friction between flanging 8 and the backing plate 5, as shown in Figure 3, pad 2 is installed between backing plate 5 and the flanging 8.
For ease of backing plate 5 is welded on the fluid bed fixed head 10, as Fig. 3 and shown in Figure 5, backing plate 5 chamfering 7 all is set up and down.
With existing fluid unit is that a large amount of experiments have been done as can be known repeatedly in the basis, and the spacing H1 between adjacent two passages 6 is 10mm, and the diameter of passage 6 is when being 3mm, and waste gas is best by the even distribution effect of fluidisation orifice plate.
The utility model not technology contents of detailed description is known technology.
