除灰

It was anticipated that more than 50% of ash and the hazardous elements As, Co, Cr, Cu, Hg, Mn and more than 30% of sulfur in most coal would be routinely removed by physical coal cleaning procedures, however, the removability of other hazardous elements Ba, Be, Cd, Cl, Mo, Ni, P, Pb, Sb, Se, Th, U, V and Zn displayed relatively lower or a wide range of variation.

结果表明：物理洗选不但能降低煤中的灰分与硫分，还能不同程度地脱除煤中有害微量元素；预测在物理洗选过程中，多数煤中灰分以及有害微量元素As、Co、Cu、Cr、Hg与Mn的脱除率大于50％，硫分的脱除率大于30％，其它有害微量元素Ba、Be、Cd、Cl、Mo、Ni、P、Pb、Sb、Se、Th、U、V与Zn的脱除率相对较低或表现出一个宽的变化范围。

研究内容包括：煤中氟与灰分、矿物成分之间的关系；煤中氟的有机亲和性与可选性；研究结果表明：煤中氟质量分数与灰分质量分数之间呈正相关关系；中国煤中氟质量分数与灰分之间存在以下指数增长关系；煤中氟质量分数与煤中矿物质的成分有关；煤中氟属"中等无机型"元素，无机亲和力较强，有机亲和力较弱；煤中氟以无机氟为主，有机氟为辅的方式赋存；原煤洗选是脱除煤中氟的一种可行的技术措施。

The results indicate that the mass size distribution of fly-ash particles in the inlet of the WFGD system is typically disturbed bimodally, the peaks are approximate at 1 and 3 μm. And the shape of particles is regular sphericity, the mass ratio of PM2.5 to PM10 is about 0.434. The total mass concentration is about 85 mg/m3. In the outlet of the WFGD system, the mass size distribution of fly-ash particles is also bimodal. The proportion of fine particles increased, the mass ratio of PM2.5 to PM10 is about 0.764. Some fine particles are conglutinated and formed irregular agglomerate. The total mass concentration is under 23 mg/m3, the removal efficiency of total particles is 74.5%. The size removal efficiency is decreased observably with the range of particle size decreasing.

结果表明，WFGD系统入口飞灰质量粒径呈典型的双峰分布，峰值分别在1和3 mm处，颗粒多呈规则球形，PM2.5与PM10质量比为0.434，飞灰总浓度约为85 mg/m3标准状态；出口处飞灰质量粒径分布也呈现双峰性，其中细颗粒比例增大，PM2.5与PM10质量比为0.764，细颗粒间相互聚集粘连形成不规则的块状结构，飞灰总浓度在23 mg/m3以下，总飞灰的脱除效率为74.5%，分级脱除效率随粒径减小而明显下降。

The degree of the plumping of the cattle hide and the removal of the hair were evaluated during the li- ming process;the protein,suspending substance,sodium sulfide and effective calcium oxide contents in the liming liquor and the fat content in the limed hide were measured;also,the tissue slice of the limed hide was observed by optic microscope.

将不同量的十二烷基硫酸酯钠、十二烷基三甲基氯化铵和平平加O分别添加到浸灰液中，观察浸灰过程中皮膨胀情况和毛脱除情况，测定浸灰废液中蛋白质、悬浮物、硫化钠和有效氧化钙含量及浸灰皮油脂含量，并对浸灰皮组织切片进行显微镜观察。

In addition to the current categories of dust equipment: bag filter, ESP, air force plane lost ash, cyclone and dust collector for a long time manufacturers and users ESP supporting equipment; screw conveyor, wetting blenders, dry bulk of the ash, Dumping of ash valve, polyester bags and bags of the cage, and so on.

目前除烟尘类目设备：袋式除尘器、电除尘器、气力输灰机、旋风除尘器并长期为除尘器厂家和用户提供除尘器配套设备；螺旋输送机、加湿搅拌机、干灰散装机、卸灰阀、涤纶布袋和袋笼等。

Therefore, in power plant ash handling system, the need for longer service life of the hard seal ball valve.

因此，在电厂除灰系统中，需要使用寿命更长的硬密封球阀。

Back in "Rites - Adam", that is the "wall Chilong＇s palm house except to mirage carbon attack, to sprinkle poison of gray" and "Tobacco＇s palm to ignore, the burning of male hegemony, to sprinkle the ashes "and so the system is to use gray to attack the rich debugging.

早在《周礼-秋官》中，即有&赤龙氏掌除墙屋，以蜃炭攻之，以灰洒毒之&及&烟氏掌去无视，焚牡霸，以灰洒之&等制度，就是用灰来攻除虫富。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
