Technical scheme and technical notes

The 1 technical scheme

In order to effectively remove residual oil, emulsified oil, machinery oil, as well as the suspended material in the water, the program will adopt pre filter, a fine filter and coalescer series, will oily water filtration and deoiling process. Among them, the filter is the role of the water a large particle impurities and flocculation of colloid removal; fine filter is a small particle impurities, as a protective coalescer, prolong the service life of a coalescing filter element; coalescence separator using the most advanced international effective oil-water separation technology - coalescence separation technology production into. In the scheme, coalescence separator 's role is to remove the residual oil in water, can make the oil content of water drops to below 10ppm, through the coalescing filter element adjustment, can also be a line to less than or equal to 5ppm. Based on the pre filter, fine filter and coalescence separator filter variety, quantity, size, material, precision is scientific and reasonable configuration, improve the filter pollutant capacity and efficiency of oil removal, and the extension of a coalescing filter element life cycle, enterprises save operation cost.

2 technical principle

The working principle of A, pre filter:

Pre filter is mainly used as a fine filter, coalescing separator, flow control valve, the protective front filter. In a fluid particle pollutants in more serious situations. At the same time, prolong the service life of the filter core of coalescence. Pre filter according to the user to provide water pollution degree and flow, using different media filter. Filter backwash can be used for a long time, without changing the basic.

The device uses a model: YGL400

Stainless steel wire mesh filter, filter precision is 50 micron.

Single pre filter technology index:

( 1): 0.6MPa design pressure

( 2) the diameter of the cylinder: 1500mm

( 3) length of the equipment: 5200mm

( 4): import and export of diameter DN250

( 5): filter specifications for 62 x 1000 ( unit: mm)

( 6) filter number: 200

( 7) a single filter flow: 200T / h

( 8): 50 micron filtration accuracy

The working principle of B, a fine filter:

Pre filter for coalescence separator, flow meter, control valve, protective front filter, and removal of small impurities, and prolong the service life of the filter core of coalescence.

The device uses a model: JGL200

The United States water stream using filter paper made of precision filter, filter precision is 5 micron.

Single pre filter technology index:

( 1): 0.6MPa design pressure

( 2) the diameter of the cylinder: 1500mm

( 3) length of the equipment: 5200mm

( 4): import and export of diameter DN250

( 5): filter specifications for 62 x 1000 ( unit: mm)

( 6) filter number: 200

( 7) a single filter flow: 200T / h

( 8): 5 micron filtration accuracy

The working principle of coalescence separator:

Coalescence separator is arranged inside the coalescence strainer. The removal of oil medium by coalescence separator inlet into the housing, the coalescence strainer tray distribution and a coalescence filter, liquid from the coalescer filter element inner to the outer, coalescence filter composed of hydrophilic oleophobic hydrophobic and lipophilic two material produced by multiple folds of filter material processing, can achieve oil and water separation effect, at the same time separating trace oil coalescence in the filter surface, forming large oil concentration in the coalescer upper, may be regularly or irregularly oil through the oil discharge valve discharge. With the solid particles in the filter layer deposited on the internal surface and the increase in the number of filter element, internal and external pressure will gradually increase, this will be the differential pressure gauge is displayed, when the pressure difference reaches 0.1Mpa, illustrate the filter has been blocked, should be replaced or backwash.

Single coalescence separator technology index

( 1): 0.6Mpa design pressure

( 2) the diameter of the cylinder: 2200mm

( 3) the import and export standards: DN250

( 4) design: 2.8 metres high

( 5): 96 x 1000mm filter specifications

( 6) cartridge number: 200

The 3 device performance characteristics

( 1) shell in strict accordance with the GB150---1998 steel pressure vessel and related industry standards for design, manufacturing, testing, and can meet the requirement of technical examination of pressure vessel.

( 2) filter corresponding dynamic fluid flow analysis and wear resistance analysis and calculation, the internal structure of the layout more scientific, more perfect performance of filtration.

( 3) this device is provided with a coalescer filter element ( need regular replacement ).

( 4) filter on the flow, temperature changes affecting the small pressure loss, small, a large quantity of pollutants, high efficiency of oil removal, long service life, economic and effective.

( 5) housing design is reasonable, the two ends of the shell are left with artificial, convenient filtering core replacement, effectively reduce the labor intensity of the operation and maintenance personnel, equipment maintenance costs low.

Two, work flow

[ precipitation pool, three separator ], pre filtering system, fine filtration systems, water oil coalescence system (which precipitate pool, three separator not included in my company responsible for the project. )

The water to purify the sedimentation tank for precipitation, so that the impurities under the action of gravity sedimentation, achieve the coarse filtration effect. Then the water to purify the precision of 300 for the purpose of backwashing the filter, filter larger solid particulate impurities. Then enter the precision is 5 micron fine filter, filter out particles larger than 5 microns impurities, to protect the coalescer was not larger impurities block, prolongs the service life of the equipment. Finally enter the coalescence separator, after coalescence, settling two processes, to effectively remove the oil in water, purifying effect is achieved.

Filtered index: filter after the water particles less than 5 microns, filtered water oil is less than or equal to 7PPM.
