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、基本結(jié)構(gòu)IV. Basic Structure砂過濾主要由頂板、底板、側(cè)板、葉片孔板、葉片盲板

6、、葉片包邊、接砂箱、配重棒、特殊環(huán)氧樹脂等組成。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砂過濾器具體結(jié)構(gòu)見下圖：Specific structure of ZHKT-FS/SUS/980X1880X604 sand filter is as below: 1底板

Filtration Principle 此砂過濾器采用了阿基米德螺旋線形結(jié)構(gòu)。其工作原理是含塵砂氣體由

8、入口沿葉片切向進(jìn)入寬度漸縮的內(nèi)部螺旋通道，在離心力與匯流流場的作用下，砂塵被拋向螺旋通道的外壁上，外壁表面風(fēng)速低于螺旋腔體內(nèi)風(fēng)速，有利于砂塵沿壁面成拋物線滑落到集砂口被收集起來。干凈氣體最后由螺旋腔體內(nèi)壁百葉孔擠入出風(fēng)口，進(jìn)入空調(diào)機組。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線形結(jié)構(gòu)，可使砂塵分離空間充分形成切向流場，并減少徑向流場的匯流作用，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. 砂過濾器運行原理見下圖：Operation principle of sand filter is as below:出風(fēng)方向 Air outlet direction 進(jìn)風(fēng)方向 Air intake direction 六、漏砂量測試運行圖及基本參數(shù)VI.
