Oil mist filter of lubricating oil station

  In the leading city of heavy chemical industry, all kinds of large, heavy and high-speed equipment generally use centralized circulating oil supply lubrication, rely on lubricating oil to reduce friction, and bring the waste heat and system pollutants generated during equipment operation back to the oil tank for centralized cooling and filtration, resulting in a large amount of oil fume, which needs additional treatment
Especially for large compressor and steam turbine customers, the treatment of oil fume even affects the normal operation of the equipment
With the improvement of national emission standards, enterprises' understanding of potential safety hazards is also changing, PM2 5 problems and the goal of energy conservation and consumption reduction have become an important work in equipment management
Therefore, the high-efficiency oil mist separation device of Changzhou Viking has been more and more widely used

Harm of oil fume
1、 Affect health
Oil fume is a kind of aerosol substance, which belongs to typical PM2 Toxic waste gas seriously affects the health of production personnel Modern medicine shows that a large number of small liquid oil droplets contained in oil fume can be suspended in the ambient air for a long time, causing asthma and other diseases
Long term inhalation will even cause lung cancer or loss of lung function

2、 Cause potential safety hazards
According to API standards, the negative pressure of the oil tank of the compressor supporting lubrication system must be adjustable up and down at 0-2kpa
The negative pressure of the oil tank can ensure that the overheated oil fume at the main lubrication point can be brought back and discharged out of the tank smoothly
Insufficient negative pressure is easy to cause oil leakage at the bearing and dynamic seal, which is a serious potential safety hazard in the explosion-proof site
Oil stains attached to the surface of high-temperature equipment and inside electrical equipment are easy to cause fire and threaten the normal operation of the equipment

3、 Waste energy
Taking the standard power oil station of l400l / min as an example, if only the smoke exhaust device with initial effect separation is adopted, it needs to supplement about 200-250l lubricating oil every month on average

4、 Affect the environment
The oil fume directly discharged adheres to the equipment surface or the site ground, forming oil stains that cannot be cleaned It seriously affects the environment and does not meet the increasingly strict requirements of on-site management specifications

High efficiency oil mist separator solution
The high-efficiency oil mist separator integrates two functions of filtration and high-efficiency separation
The core adopts coalescing separation & quot; Technology to remove oil mist in oil fume

● rule for coalescing
The high-efficiency coalescence separation filter element is composed of a variety of materials with different characteristics
The coalescence and separation materials currently used are all German products
It can ensure the use effect
Different materials have different filtration voids, surface tension characteristics and lipophilic / hydrophilic, hydrophobic / hydrophobic polarity
Through the combined use of different materials, three purposes of filtration, coalescence and separation can be realized, so as to ensure the separation effect

Filtering
In addition to oil fume, the oil mist also contains various solid particles
The existence of solid particles will affect the coalescence and separation effect and greatly reduce the service life of the filter element We design high-efficiency deep filtration before coalescence separation layer, and the flue gas can pass through coalescence separation filter element after deep filtration, so as to greatly improve the service life of filter element

● coalescing
Coalescence is carried out according to the different surface tension of the medium
The coalescence layer is composed of 3-4 kinds of multi-layer winding materials
Through the specially designed gas channel structure, the structural change of flue gas from small oil vapor to large oil droplets is realized
Sino Thai coalescence separation filter element has large throughput and strong coalescence capacity
It can be used in the harsh environment of saturated oil mist for a long time
It has incomparable advantages over traditional methods such as sintering method and felt laying method

● separating
The flue gas passing through the coalescing filter element will enter the separation layer of the filter element
Driven by gas, large oil droplets move forward, collide and polymerize with the separation layer due to lipophilic / oleophobic polarity, and settle to the bottom of the container due to gravity

● discharging
The oil separated from the oil fume fan is very clean and can be used directly
Sino Thai oil mist separator shall be in accordance with api614 oil station P & amp; According to the design requirements of ID system diagram, special oil drainage pipeline shall be reserved, and the pipeline shall go deep below the low liquid level
