填料壓柵：填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)壓(ya)(ya)緊(jin)(jin)器(qi)又稱填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)壓(ya)(ya)板。常用的(de)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)壓(ya)(ya)緊(jin)(jin)器(qi)制成柵板形(xing)(xing)狀,自由放置于(yu)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)上端靠自身重量將填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)壓(ya)(ya)緊(jin)(jin),它適用于(yu)金屬，陶(tao)瓷、石墨，塑料(liao)(liao)制的(de)散裝(zhuang)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)。作(zuo)用用于(yu)高(gao)(gao)氣(qi)速(高(gao)(gao)壓(ya)(ya)降)和負荷(he)突(tu)然波動時,阻止填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)產生(sheng)相對運動,從而避免填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)松動、破損。由于(yu)金屬，陶(tao)瓷、石墨，塑料(liao)(liao)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)的(de)破損,使碎(sui)屑淤積在(zai)床(chuang)層(ceng)(ceng)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)的(de)空隙(xi)間·使填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)的(de)空隙(xi)率(lv)下降;填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)松動、流(liu)失會(hui)造成氣(qi)液流(liu)動的(de)不均勻性(xing)加劇,這些都會(hui)使填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)塔的(de)生(sheng)產能力及(ji)分(fen)離效(xiao)率(lv)下降。對于(yu)散裝(zhuang)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)有時裝(zhuang)填(tian)(tian)(tian)(tian)(tian)不均勻,在(zai)操作(zuo)過程中也會(hui)使床(chuang)層(ceng)(ceng)發生(sheng)變(bian)化(hua),使填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)下沉,自由放置在(zai)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)上端的(de)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)壓(ya)(ya)緊(jin)(jin)器(qi)就是為了隨著填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)一(yi)起下落(luo),緊(jin)(jin)緊(jin)(jin)壓(ya)(ya)住填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)而不會(hui)形(xing)(xing)成填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)松動。因此(ci)散裝(zhuang)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)壓(ya)(ya)緊(jin)(jin)器(qi)必須有一(yi)定(ding)的(de)重量。一(yi)般情況下,壓(ya)(ya)降大、塔徑大應取大值(zhi)。

填料壓柵由金屬材料根(gen)據(ju)需要(yao)可采(cai)用(yong)碳鋼(gang)、304、304L 310 321 316 16L等(deng)材質加工而成(cheng)(cheng)。小(xiao)直徑制成(cheng)(cheng)整體式，大直徑塔制成(cheng)(cheng)分塊式，由人孔進入(ru)塔內安裝。要(yao)求空隙率(lv)大于70%，為防止填料從柵條(tiao)間(jian)(jian)隙漏(lou)出(chu)，柵條(tiao)間(jian)(jian)距應定為填料外徑的(de)0.6~0.8倍。或者采(cai)用(yong)在其(qi)底部墊金屬網（一般用(yong)鋼(gang)板網）的(de)辦(ban)法加大柵條(tiao)間(jian)(jian)距，其(qi)重(zhong)量必須滿足1.1-1.4KPa壓強的(de)要(yao)求，否則也可增(zeng)加荷(he)重(zhong)。這(zhe)種形式的(de)優(you)點是結構(gou)簡單，制造方便。
