例如格孔為φ40mm的普通七孔格子磚的熱交換死區(qū)為％，由于熱交換死區(qū)的存在勢(shì)必影響熱交換效率。這對(duì)于提高鼓風(fēng)溫度十分不利。因此采用普通七孔格子磚和高爐煤氣，送風(fēng)溫度一般只能達(dá)到1100～1150℃，而隨著高爐噴煤的普及和噴煤量的增加對(duì)風(fēng)溫要求越來(lái)越高，為滿足這一要求而研制此實(shí)用新型。本實(shí)用新型的目的是以改變格孔的形狀和格子磚的結(jié)構(gòu)，減少或消除熱交換死區(qū)，在不降低單位容積格子磚重量的前提下，增大單位容積格子磚的熱交換面積，達(dá)到提高熱交換效率，以利于提高鼓風(fēng)溫度。本實(shí)用新型的目的是這樣實(shí)現(xiàn)的所述的梅花形格孔七孔格子磚，是由格孔(1)、相互平行的上頂面(2)和下底面(4)、及側(cè)壁(3)構(gòu)成。其特征在于該格子磚的格孔的橫斷面是由l2條圓弧組成的梅花形格孔，它的7個(gè)格孔均垂直貫穿上項(xiàng)面(2)和下底面(4)，格孔的分布是中心有1個(gè)格孔，其余6個(gè)格孔以中心格孔為對(duì)稱中心，格孔間距相等，均勻地分布在六個(gè)方向，相鄰格孔的鄰邊相互對(duì)應(yīng)，并向各自格孔的中心凸出．上頂面(2)和下底面(4)的形狀為等邊長(zhǎng)異形六邊形(見(jiàn)附圖1)。本實(shí)用新型的目的可以是這樣實(shí)現(xiàn)的梅花形格孔的大小是根據(jù)設(shè)計(jì)需要確定弧心圓的半徑R。廣元PVC七孔梅花管廠家</p></p><br
