Now, with the food safety problems such as gutter oil being exposed constantly, it is urgent to separate, recycle and centrally treat oil and water. Therefore, oil-water separator has attracted more and more attention from consumers. Let me show you what kinds of oil-water separators there are.
1. Oil-water separator for air compressor
The compressed air oil-water separator is used to separate condensed impurities such as water and oil in compressed air, so that the compressed air can be preliminarily purified. Generally, the operating pressure is 1.1Mpa- 2.5Mpa.
Working principle of compressed air oil-water separator:
When compressed air enters the oil-water separator, the flow direction and speed change sharply, and then oil droplets and water droplets with higher density than compressed air are separated by inertia. The common ones are impact oil-water separator and annular rotary oil-water separator. After the compressed air enters the shell of the oil-water separator from the inlet, the air flow is first blocked by the baffle plate, then bounces back down, and then rises up again, resulting in annular rotation. In this way, water droplets and oil droplets are separated from the air and settled at the bottom of the shell under the action of centrifugal force and inertia force, and the oil droplets can be discharged by opening the bottom valve regularly, and the preliminarily purified air is sent to the gas storage tank from the outlet.
ii. marine oil-water separator
on July 8, 2113, the Marine Environmental Protection Committee under the International Maritime Organization passed the resolution IMO.MEPC.117(49). This resolution puts forward new requirements for Annex I of MARPOL 73/78 on YWC 15ppm bilge oil-water separator. The marine oil-water separator can effectively treat the bilge water containing various fuel oils, high-density residual oil and emulsion mixture prepared by iron oxide and surfactant.
iii. Oil-water separator for vehicles
The models with high-pressure rail engines under the national standard III also require higher diesel quality, because the high-pressure nozzle needs to accurately control the injection pressure, injection time and injection quantity, so it requires exquisite workmanship. If there is water or impurities in diesel oil that are not filtered clean, it will wear the plunger coupling in the fuel injector and cause strain until the fuel injector is stuck. Damage to the fuel injector will lead to unstable or weak acceleration of the engine, or black smoke emission, which will affect the normal operation of the vehicle.
as the first stage of the multi-stage filter system, the primary fuel filter has the function of filtering out large particles of impurities and moisture. The water separation efficiency of the filter is required to reach 95% according to the requirement of fuel pressure in the third national emission standard, but many coarse filters can't achieve this filtering effect, which will cause damage to the engine over a long time.
iv. Oil-water separator for catering
The oil-water separator for catering is mainly suitable for the environment seriously polluted by oily sewage discharge in China. The oil-water separator is an imported "grease trap" installed at the outlet of the sewer to prevent oil and garbage from being discharged into the sewer. It is mainly made of FRP, stainless steel and other materials. Due to the advanced design (the product and its design have been patented at home and abroad), the oil blocking rate can reach more than 91%.
these are the types of oil-water separators that I introduced to you, and they are used in different places. Consumers must know the relevant knowledge in advance before buying, and pay attention to the quality of the product. If it is difficult to use because of the price factor, it will not be worth the candle.
