填料壓圈又(you)稱填(tian)(tian)料(liao)壓(ya)(ya)(ya)(ya)板或(huo)填(tian)(tian)料(liao)壓(ya)(ya)(ya)(ya)蓋、填(tian)(tian)料(liao)壓(ya)(ya)(ya)(ya)柵(zha)、填(tian)(tian)料(liao)壓(ya)(ya)(ya)(ya)緊(jin)(jin)器(qi)(qi)。是常用(yong)的(de)填(tian)(tian)料(liao)壓(ya)(ya)(ya)(ya)緊(jin)(jin)器(qi)(qi)制(zhi)成(cheng)柵(zha)板形狀，自由放(fang)(fang)置(zhi)在填(tian)(tian)料(liao)上(shang)端，靠自身重(zhong)力將填(tian)(tian)料(liao)壓(ya)(ya)(ya)(ya)緊(jin)(jin)。它適用(yong)于陶瓷、石(shi)墨制(zhi)的(de)散(san)堆(dui)填(tian)(tian)料(liao)。其作用(yong)是高氣速（高壓(ya)(ya)(ya)(ya)降(jiang)(jiang)）和負荷突(tu)然(ran)波動時(shi)，防(fang)止填(tian)(tian)料(liao)層松動、破(po)損。散(san)裝(zhuang)填(tian)(tian)料(liao)松動、架橋，會(hui)加(jia)劇氣液流(liu)動的(de)不均勻性，從而(er)降(jiang)(jiang)低塔(ta)的(de)分離效(xiao)率；如果破(po)損，則(ze)填(tian)(tian)料(liao)碎屑會(hui)淤積在床(chuang)層填(tian)(tian)料(liao)的(de)空隙中，使(shi)填(tian)(tian)料(liao)層的(de)空隙率下降(jiang)(jiang)，影(ying)響(xiang)塔(ta)的(de)通量(liang)。對于散(san)堆(dui)填(tian)(tian)料(liao)，有時(shi)因裝(zhuang)填(tian)(tian)不均勻，操作過程(cheng)會(hui)造成(cheng)填(tian)(tian)料(liao)層下沉，自由放(fang)(fang)置(zhi)地填(tian)(tian)料(liao)層上(shang)的(de)壓(ya)(ya)(ya)(ya)緊(jin)(jin)器(qi)(qi)能隨填(tian)(tian)料(liao)一(yi)(yi)起下沉，緊(jin)(jin)緊(jin)(jin)壓(ya)(ya)(ya)(ya)住填(tian)(tian)料(liao)不使(shi)其松動，因此(ci)散(san)裝(zhuang)填(tian)(tian)料(liao)壓(ya)(ya)(ya)(ya)緊(jin)(jin)器(qi)(qi)必須有一(yi)(yi)定的(de)重(zhong)量(liang)。一(yi)(yi)般壓(ya)(ya)(ya)(ya)差大(da)、塔(ta)徑大(da)，重(zhong)量(liang)也要大(da)。

填料壓圈、填料壓柵（填料壓緊柵板）：它由金屬材料根據需要可采用碳鋼、304、304L 310 321 316 16L等材質加工而成。小直徑制成整體式，大直徑塔制成分塊式，由人孔進入塔內安裝。要求空隙率大于70%，為防止填料從柵條間隙漏出，柵條間距應定為填料外徑的0.6~0.8倍。或者采用在其底部墊金屬網（一般用鋼板網）的辦法加大柵條間距，其重量必須滿足1.1-1.4KPa壓強的要求，否則也可增加荷重。這種形式的優點是結構簡單，制造方便
