渦輪機油再生裝置 - CMM-6RL

渦輪機油用於蒸汽和燃氣輪機的各種渦輪發電機組、水輪機和渦輪壓縮機機的軸承潤滑和冷卻。

使用渦輪機油的主要問題是需要確保長期的物理和化學性質的穩定性。要做到這一點並不容易，因為油的操作條件很困難，其特點是局部溫度高，暴露於大氣中的氧氣，受到機械雜質的污染等。上述因素破壞了油的持有特性。據統計，高達20-25%的動力渦輪機的故障、缺陷和損壞是由於與渦輪機油的品質下降和性能惡化相關的原因造成的。

液壓油的污染和老化

在液壓系統的所有故障中，80%以上都與灰塵、鐵鏽和各種纖維的污染以及設備運行過程中油品的老化有關。

如果通過在系統中安裝固定式過濾器來調整機械雜質的存在和數量，那麼老化意味著導致油的主要操作性能喪失、沉澱和過濾器堵塞的過程。老化的液壓油通常被換成新油，然後被倒掉處理。然而，在大多數情況下，液壓油的使用壽命在更換時並沒有過期，在再生後，油仍可進一步用於其預定用途。

CMM-6RL裝置中的渦輪機油再生

因此，渦輪機油在進入動力渦輪機的油路系統之前，以及在運行過程中，都應定期進行淨化。為此，在機械過濾器、分離器、離心機、靜電淨化器和真空乾燥器中使用並實現了不同的原理。然而，這種設備最常見的目的是去除機械雜質和水；然而，它並不能去除老化產品（酸性化合物等）。

老化的渦輪機油不能發揮其功能，持續使用下可能導致動力渦輪機的故障，隨後是漫長而昂貴的維修。現在，在大多數情況下，老化的渦輪機油被換成了新油，儘管用過的油含有有用的碳氫化合物，如果採用正確的方法，可以根據其預定用途進行回收再利用。

渦輪機油再生的CMM-6RL裝置操作特點

CMM-6RL裝置的主要特點是可以在不從再生圓柱中取出吸附劑的情況下進行重新活化。如果使用過的吸附劑應在具有類似預期用途的其它設備中處置，GlobeCore 技術可確保通過燃燒回收吸附劑，並重複使用其再生液壓油（至少 300 次再活化）。

操作週期的持續時間和耗電量

CMM-6RL裝置用於渦輪機油的再生，在以下模式中順序運轉：

1. 油再生（持續時間-6 h，消耗功率-1.5 kW/h）。
2. 吸附劑的重新活化：

• 準備工作（持續時間-1 h，消耗功率-6.25 kW/h）。
• 吸附劑點燃（持續時間-1 h，消耗功率-17.5 kW/h）。
• 吸附劑燃燒（持續時間-15 h，消耗功率-25.5 kW/h）。
• 填充（持續時間-0.5 h，消耗功率-6.5 kW/h）。

優勢

• 操作方便。該裝置通過雙扣式快速接頭快速連接到清潔和骯髒的油槽；油的淨化過程通過玻璃視窗進行可看見的監控；在再生圓柱的底部有一個服務艙口，用於維護和清洗。
• 該裝置可以在自動模式下運轉。選擇所需的操作模式，通過顯示單元助記符號的觸控螢幕來控制轉動裝置。為了啟用控制按鈕，操作員只需觸摸它們。
• 吸附劑無需從裝置中取出即可回收，冷卻後可立即用於下一個再生循環。在最後一次的活化結束時，吸附劑可以作為建築骨料或在農業中用來鬆動緊實的土壤。
• 在設備運轉過程中，不會出現向環境中排放有害氣體的情況。該裝置配備了一個用於中和燃燒產物的雙級系統，該系統由一個碳過濾器和一個催化轉化器組成。

Turbine oils are used for lubrication and cooling of bearings in various turbogenerator sets of steam and gas turbines, hydraulic turbines, and turbocompressor machines.

The main problem in usage of turbine oils is the need to ensure the stability of physical and chemical properties over a long period. It is not easy to do because of difficult operating conditions of oil which are characterized by high local temperatures, exposure to atmospheric oxygen, contamination with mechanical impurities, etc. The mentioned factors disrupt the operational properties of oil. Statistically, up to 20–25% of failures, defects, and damages of power turbines are due to the causes associated one way or the other with degraded quality and deteriorated properties of turbine oil.

Purification of turbine oil

Accordingly, turbine oils should be purified both before feeding into the oil system of power turbines and periodically during operation. For that purpose, different principles are used and implemented in mechanical filters, separators, centrifuges, electrostatic purifiers, and vacuum dryers. However, this kind of equipment is most often aimed at removal of mechanical impurities and water; however, it doesn’t manage to remove aging products (acid compounds, etc.).

Aged turbine oil is not capable of performing its functions, and its usage may lead to breakdowns of power turbines followed by lengthy and costly repairs. Now, aged turbine oil is changed for new oil in most cases, although used oil contains useful hydrocarbons and can be reclaimed for reuse according to its intended purpose if the right approach is applied.

Regeneration of turbine oils in CMM-6RL unit

CMM-6RL unit has proved its worth in reclaiming the properties of used turbine oils at nuclear and thermal power plants. It takes a different approach to oil processing in comparison with filtration, separation, centrifugation, electrostatic purification, and vacuum drying.

GlobeCore principle of turbine oil regeneration is based on pumping the turbine oil through the columns preliminarily filled with a special natural adsorbent (one column contains about 150 kilograms of adsorbent). The adsorbent absorbs all the oil aging products and subsequently retains them in its granules. The oil that has passed through CMM-6RL unit becomes purified, clarified and completely regains its operational properties; therefore, it can be reused in the oil systems of power turbines.

Operation features of CMM-6RL unit for regeneration of turbine oil

The main feature of CMM-6RL unit is the possibility to reactivate the adsorbent without removing it from the regeneration columns. If the used adsorbent should be disposed of in other equipment of a similar intended purpose, GlobeCore technology ensures reclamation of the adsorbent by burning, as well as repeated use thereof for regeneration of turbine oil (at least 300 reactivations).

1. Duration of operating cycles and power consumption
2. CMM-6RL unit for regeneration of turbine oils sequentially operates in the following modes:

• Oil regeneration (duration — 6 h, power consumption — 1.5 kW/h);
• Adsorbent reactivation:
• preparation (duration — 1 h, power consumption — 6.25 kW/h);
• adsorbent ignition (duration — 1 h, power consumption — 17.5 kW/h);
• adsorbent combustion (duration — 15 h, power consumption — 25.5 kW/h);
• refilling (duration — 0.5 h, power consumption — 6.5 kW/h)

Advantages

• Convenience of operation. The unit is quickly connected to tanks for clean and dirty oil through camlock quick couplings; the oil purification process is visually monitored by means of sight glasses; a service hatch is provided at the bottom of the columns for their maintenance and cleaning.
• The unit can operate in automatic mode. The required operating mode is selected, and the actuators are controlled from the touch panel which displays a mnemonic diagram of the unit. In order to enable the control buttons, the operator just needs to touch them.
• The adsorbent is reclaimed without being removed from the unit and can be used for the next regeneration cycle immediately after cooling. At the end of the last reactivation, the adsorbent can be used as a construction aggregate or in agriculture to loosen compact soils.
• There occur no harmful emissions into the environment during the unit operation. The unit is equipped with a two-stage system for neutralization of combustion products which consists of a carbon filter and a catalytic converter.
