干燥机说明书.docx

日常维护要点：Daily maintenance:1. 设备投入运行一个月后，应检查并填补一次吸附剂，视实际状况〔6-12 月〕全部更换吸附剂The absorbent should be checked and added after one month operation of the new equipment. The absorbent should be completely changed after 6-12 months, depending on the actual situation of the equipment.2. 定期清洗、吹扫电磁切换阀，并检查阀门运动状况The electro-magnetic switch should be regularly cleaned, and the valve should be checked.3. 前置过滤器上的自动排水器应定期清洗，确保滤筒体内不积液体To make sure that liquid will not be trapped in the cylinder, the automatic water drainer on the pre-filter should be regularly cleaned.4. 前置过滤器滤芯寿命为 8000H，到时〔或滤芯压力降达 0.07MPa时〕就更换滤芯。

The life time of the core of the pre-filter is 8000 hours, the core should be changed after 8000 hours (or when the pressure drop reaches 0.07MPa).5. 定期检查管线接头、法兰、阀门有无泄气现象Regularly check the joints, flange and valves for leakage.6. 枯燥器停用期间，请半闭好全部阀门，防止泄漏，以免吸附剂受潮All valves should be shut off when the equipment is not in operation.常见故障排解Treatment of common defects枯燥器在使用过程中消灭故障请按下表找出缘由，然后对症处理现象 缘由Phenomenon Reasons现象 缘由Phenomenon Reasons吸附效果变1.吸附剂失效吸附剂过早1.进气侧前置过滤器失效差absorbent failure老化failure of the pre-filter onAbsorbing2.处理气量过大Absorbentthe gas inlet sideefficiencytoo high gas amountages too2.前置过滤器排水阀失灵becomes3.进气温度太高earlyFailure of the drainingpoortoo high temperatureofvalve on the pre-filterincoming gas3.处理气量长期过大，进气4.工作压力太低温度长期过高too lower operationtreat too large amountpressureand/or too high5.再生气量太小temperature of gastoo low recycling gas4.管道，阀门密封效果不佳amount6. 进入枯燥器的气体含液态水、油等gas entering dryer contains liquid water, oil, etc.7. 有短路气流进入下游管线short-cut gas enters the pipeline8. 截止阀故障，关闭不全alves are not fully opened9. 电气系统故障，阀门动作不 正 确 electric system failure,压降增大Pressure drop increasesPoor sealing effect of pipes and valves1. 吸附剂老化absorbent ages2. 过滤器滤芯失效、堵塞failure of the filter core3. 管道阀门未全开valves are not fully opened4. 再生气量调整阀开的过大，有效供气削减The regulating valve for the recovered gas opens too big5. 用气量增大Gas consumption increased too much工作原理说明Working principle2 3开机后，A 塔作吸附运行，B 塔作脱附〔再生〕运行。

在预先的时序掌握下，截止阀 A1，A2 相继翻开，待处理的潮湿压缩空气经A1 进入A 塔，潮湿气流在自下而上的运动过程中，内部所含的水蒸气被布满塔内、外表有很多项选择择性小孔的吸附剂〔AL O 〕所吸附压缩空气本身得到枯燥约占总处理量 85%左右的枯燥空气经单向阀a 进入用气管网，另外约占15%的枯燥空气经节流降压后，从上部入B 塔，作自上而下的运动原先已被 B 塔内吸附剂所吸附的水蒸气在低压环境中得以释放〔脱附〕并随低压气流经A2、消声器 E 逸入大气，B 塔内的吸附剂也由此而获得活性再生Tower A absorbs and Tower desorbs after the equipment d on. Under the control of the pre-set order, the stopping valves A1, A2 are switched on, the wet pressurized air enters Tower A via A1, the water vapor is absorbed by the absorbent (Al2O3), and the pressurized air is dried. About 85% of the dried air enters the gas pipeline via one-way valve a; and about 15% dried air drops in it pressure, enters Tower B from the top and moves from the top to the bottom. The previously absorbed water vapor by the absorbent in Tower B releases (desorbs) under the low pressure environment, and escapes to the atmosphere via A2, silencer E. The absorbent in Tower B is hence recovered.在A1 进气阀关闭前约 20 秒A2 先行关闭，使 B 塔得以充压，约再经 14 秒B1 进气阀翻开。

在约有 6 秒钟的时间里，A、B 两塔同时作吸附运行，这就保证了供气的连续性A 塔工作 5 分零 6 秒后， A1 阀关闭系统进入 B 塔吸附运行，A 塔作脱附运行的下半个循环A2 shuts off about 20 seconds before A1 shuts off, Tower B is hence gains pressure. B1 is on about 14 seconds later. Towers A and B are both on the absorbing mode at the same time for about 6 seconds. Continuous gas supply is hence guaranteed. Valve A1 shuts off after 5minutes and 6 seconds operation of Tower A. The system enters the second half cycle that Tower B absorbs and Tower A desorbs.整个工作循环的时间安排，均是在电子可编程掌握器作用下自动进展。

用户视工艺需要可在 T 后面挂高其它功能过滤器以到达用气净化要求假设空压机属无油润滑型，则 A 级过滤器可免装但进气含油量必需保证在 05mg/m3 以下假设空压机排气温度较高，则应装后部冷却器，保证枯燥器进气温度＜40℃The installation method of the absorbing dryer is shown in the figure below. The pre-filter on the gas inlet side of the dryer is normally necessary. De-water filter C, de-oil filter A can prevent the absorbent from contamination liquid water drops and oil. FT (1 μm dust filter) on the gas outlet should be installed because it can prevent abrasion loss ofthe equipment by the absorbent dust. If the compressor is oil-less lubricant, then filter A can be omitted. The oil content must be below0.5 mg/m。
