5、ter holes can effectively separate air from sand. Each unit is 900W×1800 (internal dimension) with filtered air volume of 20000m3/h; multiple units can be used together. The unique sand collector at the bottom can collect and regularly dump sand.四、基本结构IV. Basic Structure砂过滤主要由顶板、底板、侧板、叶片孔板、叶片盲板

6、、叶片包边、接砂箱、配重棒、特殊环氧树脂等组成。Sand filter consists of top plate, bottom plate, side plate, blade pore plate, blade blind plate, blade edge, sand collector, counterweight bar, special epoxy resin.ZHKT-FS/SUS/980X1880X604砂过滤器具体结构见下图：Specific structure of ZHKT-FS/SUS/980X1880X604 sand filter is as below: 1底板

Filtration Principle 此砂过滤器采用了阿基米德螺旋线形结构。其工作原理是含尘砂气体由

8、入口沿叶片切向进入宽度渐缩的内部螺旋通道，在离心力与汇流流场的作用下，砂尘被抛向螺旋通道的外壁上，外壁表面风速低于螺旋腔体内风速，有利于砂尘沿壁面成抛物线滑落到集砂口被收集起来。干净气体最后由螺旋腔体内壁百叶孔挤入出风口，进入空调机组。This sand filter adopts Archimedean screw liner structure. Its working principle is as below: along tangential direction of blade, gas with dust sand enters into internal screw chann

9、el (width gradually reduce) from inlet; under the effect of centrifugal force and confluent flow field, sand dust is thrown to outer wall of screw channel; Outer walls surface wind speed is lower than that in screw cavity, which is favorable for sand dust falling into sand collecting port along the

10、wall surface as a parabola so as to be collected. Finally, clean gas squeezes into air outlet from blinder hole in inter wall of screw cavity and enters into air-conditioner unit.由于采用了阿基米德螺旋线形结构，可使砂尘分离空间充分形成切向流场，并减少径向流场的汇流作用，以提高除砂效率。Archimedean screw liner structure is adopted, which can make separa

11、ted space of sand dust sufficiently form tangential flow and reduce confluence effect of radial flow field so as to improve degritting efficiency. 砂过滤器运行原理见下图：Operation principle of sand filter is as below:出风方向 Air outlet direction 进风方向 Air intake direction 六、漏砂量测试运行图及基本参数VI.
