This research shall be obtain that ocean-sand motor shall have more compressive strength early, but later strength shall descend, by means of non-standard sand mixing sample is quite obvious. By means of 50% ocean-sand substitutes for river-sand to mix fine aggregate compressive strength early shall be risen 20%~30%; Adds slag to ocean-sand or a half of river-sand and ocean-sand to make motor test sample, Compressive strength、bending strength and tensile strength shall be according to slag additament, by means of. slag add itament substitutes for cement 40%~60% is most. But slag be able to substitute for cement is too enough, 1ater strength shall be descent.

由本研究可得知海砂拌和的水泥砂浆，其早期抗压强度较高，而晚期强度则有下降的趋势，其中以非标准砂拌和效果最为明显；若以50%海砂替代河砂做为拌和细骨材，其早期抗压强度约上升20%~30%；添加炉石於海砂或河砂、海砂各半的水泥砂浆，其抗压、抗弯及抗拉强度，会随著炉石添加量增加而增加，其中以40%~60%炉石替代量为最佳，但是炉石替代量过高，晚期强度会下降；在相同水灰比状况下以海砂拌和水泥砂浆做比较，以非标准砂拌和有较高的抗压强度，其强度约比标准砂高10%左右。

According to the existent problem of the running water film deduster which included the more pressure drop and the efficiency of low removal dust,the method was discussed by applying venturi and rotating-stream-tray and spraying and demister to reconstruct the old deduster.

针对文丘里水膜除尘器运行中存在的压降过大和除尘效率过低等问题，采用文丘里+旋流板+喷淋+折流除雾器的方法对原有除尘器进行改造。改造工程应用表明，该方案的阻力和除尘效率在理论上的分析与实际应用相一致，在文丘里喉管气速 40m/s，液气比 0 。5L/m3 ，喷淋液气比为 1.5L/m3 时，除尘效率达到 95 %以
