200t热力喷雾除氧器操作维护手册
一、用途与工作原理大气式热力喷雾除氧器是作为驱除锅炉给水中所含的溶解氧的设备，以保护锅炉免受氧的腐蚀。
给水的除氧是防止锅炉腐蚀的主要方法，在容器中，溶解于水中的气体量与水面上气体的分压力成正比，采用热力除氧的方法，即用蒸汽来加热给水，提高水的温度，使水面上的蒸汽的分压力逐渐增加，而溶解气体的分压力则渐渐降低，溶解于水中的气体就不断逸出。
当水被加热至相应压力下的沸腾温度时，水面上全部是水蒸汽，溶解气体的分压力为零，水不再具有溶解气体的能力，亦即溶解于水中的气体，包括氧气均可被出去。
除氧的效果一方面决定于是否把给水加热至相应压力下的沸腾温度，另一方面决定于溶解气体的排除速度，这个速度与水和蒸汽的接触表面积的大小有很大关系，采用喷雾、淋水盘加填料的方式，水通过喷嘴被强烈的播散成雾状下落，与上升的蒸汽流相遇，雾化的结果大大增加了水和加热蒸汽的热交换面积，强化了汽水垫交换的效果，雾状的水滴经过淋水盘换垫后继续流经无规则堆放的填料层时，受到蒸汽的进一步加热。
水的迅速被加热，溶解于其中的气体的排除速度也更快。
因此，虽然水在除氧器中停留的时间很短，而除氧效果较彻底，出水含氧量≤0.015mg/L。
二、技术参数三、设备的运行3.1 投运前的准备工作处理水量200m3/h 水箱容积60m3工作压力0.02MPa 进水温度＞20℃出水含氧量≤15ug/L 安全阀起跳压力0.06MPa 设备重量19000kg运行重量91000kg3.1.1检查除氧器管道系统应无缺陷，水封管有水封闭。
3.1.2各种仪表应齐全，指示准确。

水箱放水门、向给水泵供水门关闭。
3.2除氧器的运行3.2.1除氧器起动前应先打开上部的放气阀，并进行补水（软水），直至稍低于正常水位约200-250mm为止。
3.2.2慢慢开启水箱底部的辅助加热蒸汽阀门（不得快开），逐步加热水箱内的软水（加热速度一般不超过每分钟升温5℃），当水箱水温达到104℃后关闭辅助加热蒸汽管阀门。

CONFORMITY DECLARATION ____________________________________________ 121.I NTRODUCTIONThe machine described in this booklet is a portable welding fume extractor for extracting, filtrating and de-odorizing welding fumes for light welding operations in electronic industries and in car repairing workshops.After passing through a rotary nozzle and a flexible hose having diameter 60 mm, the polluted air reaches a filter cartridge. The final deodorization is obtained by means of a filter with active carbons.Upon delivery of the machine, make sure to check that it has not suffered any damage during transportation. Should you find that the machine is not completely intact, get in touch with our dealer immediately and do not use it.The machine must be used exclusively for the purposes for which it has been built.We decline all responsibility for any damage to persons or things resulting from improper use of the product.2.T ECHNICAL C HARACTERISTICS2.1 Technical data2.1.1 Highest EfficiencyThe high-quality filtering materials of this machine make it possible to obtain an interception efficiency of over 99%. Moreover, activated carbons remove almost all odours.2.1.2 Low Noise LevelLow noise level is possible thanks to the disposition of the inner filters and to their high absorption efficiency, and also thanks to the sound absorbent materials used in conjunction with a powerful exhauster.2.1.3 HandinessWelding fumes should always be extracted before they reach respiratory tract. Fresh and pure air is a condition that can not be given up in a salubrious working place. The solution is to extract the air where pollution takes place by means of small and easily situated extraction nozzle.The easily portable, light but reliable MW 8100 is the right solution to dealing with these fumes.2.2 Working modePolluted air is extracted by means of the nozzle (part. 1, picture 1), equipped with a magnetized base that allows its safe placing. It passes through the flexible hose (part. 2, picture 1) and reaches the machi ne inlet flange (part. 3, picture 1), when there’s a labyrinth that prevents sparks from reaching the CARTRIDE filter (part. 4, picture 1). The air flow passes the CARTRIDE filter and then the cell with activated carbons (part. 6, picture 1).Inside the machine, made up of a sturdy painted sheet steel, there is the electric motor (part. 5, picture 1). picture 1 – MW 8100 PARTSPos.Description 1 Nozzle with magnetized base 2Flexible hose 60, L=3000 mm 3Machine inlet flange 4CARTRIDE filter 5Electric motor 6Activated carbons cell 7 HandleTable 2 – MW 8100 PARTS23 4 61 7 52.3 Overall Dimensions Picture 2 – MW 8100 overall dimensions3.

电除雾器使用说明书
1、由电工按要求仔细检查调整高压整流机组、绝缘箱温度、传感器安装位置是否准确，检查调整无误后方可使用。
2、检查供电系统的所有设备，检查电场对地绝缘电阻是否合格，电除雾器本体接地电阻应小于1“Ω”方可送电。绝缘箱远红外加热器在开车前24小时应通电升温，温度升至1300C±100C才可，若长期停车后再开车，仍应在温度达到以上额定值，恒温24小时方可使用。检查恒温检测仪表，灵敏可靠，能自动调节温度至规定值。
冲洗水压：≥2公斤/厘米2
除雾效率：≥98%
三、工艺操作条件：
1、通常硬聚氯乙烯塑料在600C以上即开始软化，因此塑料电除雾器的正常操作温度不得超过450C，高于450C即为事故，应立即采取措施。
2、硬聚氯乙烯本身强度较低，脆性大，虽经加固措施，但最大操作负压应≤－800毫米水柱，通常在进口管道上装有安全水封，超过此负压水从安全水封抽掉，应立即停车，消除隐患，查明原因后再用。
电除雾器使用说明书
一、玻璃钢电除雾器的工作原理：
电除雾器是用高压直流电、电场驱动炉气内微细粒子，使其加速沉降于沉降极（阳极）表面以除去炉气中酸雾的设备。将40千伏的直流高压电引入器内，使悬挂在器内的电晕极不断发射出电子，把电极间部分气体电离成正负离子，尘雾等颗粒碰到离子而荷电，按照同性相斥、异性相吸的原理，荷电后的尘、雾颗粒各向电极性相反的电极移动，正离子向电晕极移动，而电子和负离子则移向沉淀电极。分散在气体中的尘雾与带负电离子相碰而荷电，在电场的作用下，带电的酸雾颗粒移向沉淀极内壁上，靠自重顺壁而下，落入电除雾器的下封头内，炉气得到净化。
（3）、工作人员进入设备检查和维修时，注意不要碰动大梁和电晕线。人体进入器内，手脚要轻，不准摇摆电晕极架，以防石英管损坏。

维护手册烟气脱硫除雾器TME-I型
目录
1、检查
2、维护
3、运输及存放
1 检查
在机组未运行期间，应该对除雾器进行定期检查。
检查内容包括：
✧是否结垢
✧是否堵塞
✧是否有硬垢
✧除雾器板片有无机械损伤
✧其他部件的有无机械损伤
✧管道和连接件有无机械损伤
✧其他部件的有无机械损伤
✧喷嘴是否脱落
✧管道支撑的安装是否安全
✧除雾器是否有腐蚀现象
✧防腐层是否有腐蚀现象
✧防腐层是否有损伤现象
✧除雾器的是否有错位现象
✧喷嘴或喷管是否有堵塞现象
✧管道是否泄露
✧阀门功能是否正常
✧吸收塔内外的螺栓连接点是否牢固
检查时重点要放在与规定状况不相符合的地方和与上次检查时有明显变化的地方。
一旦发现有这种情况，就必须查明原因。
在查找原因时，应注意弄清楚这些异常情况是与除雾器的运行有关还是FGD的运行有关。
如果这种变化将给运行带来问题，就应该查明造成这种变化的原因以及了解这种变化会引起的后果，应决定是否可以和应该采取补救措施。
对结垢和堵塞应该进行判断和分析。
结垢和堵塞表明要么是冲洗系统故障引起的，要么是除雾器故障引起的。
此外，应该对结垢程度进行判断，它是否可以被冲洗掉还是属于硬结垢。
结垢和堵塞的形状应该与上次检查的结果进行比较。
如果在同一地方频繁出现结垢和堵塞，就应该采取措施，保证该区域在今后保持清洁。
补救措施包括更换冲洗喷嘴，增加喷嘴或改变喷射角度等。
如发现有机械损伤，应判断它是由于维护不当造成的还是由于操作失误引起的。
如果是由于运行原因引起的，就应该彻底查找原因。
维护原因造成的损伤与运行没有关系，但两个方面都要进行检查。
如果损伤表明是由于材料严重老化，那么就建议更换除雾器。
如果除雾器使用寿命已达到，然而还在继续使用，会引起更为严重的问题。
如果损坏会造成安全或运行上的隐患，则应该进行修复或用备件更换。
如果有腐蚀迹象，则需要进行修复，同时应采取措施减少冲洗水中的固体含量。
2 安全
在检修和维护期间，建议只能在支撑梁上行走。
如果需要跨过支梁，应该铺设木跳板。
不得在支梁以外的除雾器的任何部位件上行走。
应该知道，长时间以后除雾器将会变脆弱而强度削弱。
聚丙稀会老化从而强度减弱。
3 维护
沉淀物
如果在除雾器上有些沉淀物污垢堵塞，硬垢，在检查时应该判断出这种情况处于正常范围内还是存在问题需要采取特殊措施。
这些沉积物应该用冲洗水冲走。
冲洗用的水应该是没有压力的，因为高压可能损坏除雾器和支撑梁防腐层。
当绝大多数的沉积物被冲走之后就算冲洗结束。
机械损伤
如果发现有机械损伤情况，应该判断出这种机械损伤是由于操作问题造成的还是在检修维护过程中造成的。
再作决定是否需要采取修补措施。
如果需要对损伤的地方进行处理，应决定是由自己处理还是需要由供货方服务人员来处理。
错位
由于振动，冲洗和维护的原因，除雾器可能会发生移位的现象。
如果是这样，就应该重新复位。
