oil-water separator, I wonder if you have heard of it? In fact, it is still widely used in life, mostly used in catering and shipping fields. Next, let's take a look at the related content of oil-water separator.

I. Catering Oil-Water Separator of Oil-Water Separator

1 Introduction of Catering Oil-Water Separator

The catering oil-water separator of oil-water separator is mainly suitable for the environment with serious pollution caused 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%.

2 Features of catering oil-water separator

(1) Low price, no consumable parts, and one-time investment benefits all the year round.

(2) There is no need for electricity and power, and there is no need for operating expenses. It is completely self-purification after sewage flows in, which is convenient for management.

(3) The material is hard, easy to clean, and has a long service life.

(4) Prevent the sewer from clogging, avoid the breeding of rats and insects, odor overflow and unnecessary cleaning caused by rotten oil, and prolong the service life of the sewer.

ii. Marine oil-water separator of oil-water separator

1 Introduction of marine oil-water separator

The marine oil-water separator of oil-water separator can effectively treat the ship's bilge water containing all kinds of fuel oil, residual residue with extremely high density and emulsion mixture prepared by iron oxide and surfactant. A machine for separating oil from water is usually used by ships to treat sewage. Because of the requirements of environmental protection, the sewage discharged into the machinery of ships in rivers, lakes and seas must be treated.

The grease trap is a box structure, which can be buried underground or on the ground. After the anti-skid box cover is opened, the sewage flows into the residue trap chamber through the inlet, leaving solid substances. The sewage flows into the grease trap chamber through the lower edge of the partition, and a large amount of grease floats on the surface after gravity separation. The degreased water flows into the grease trap chamber through the lower edge of the partition, and the grease floats on the surface again. The degreased sewage outlet flows into the unified and standardized clean water sampling chamber stipulated by the State Environmental Protection Agency, which is convenient for sampling and is discharged through the discharge pipe.

2 working principle of oil-water separator

working principle and workflow of oil-water separator system: 1 water enters from AOD pump (air diaphragm) --> 2 Flow control valve enters --> 3. The first-stage honeycomb chamber is flushed with water. Because there are many compact honeycomb compartments in it, tiny particles in the water settle in the honeycomb chamber during the water flow, and wastewater flows in --> 4 mesh water distribution holes (5/32 ") enter --> 5 adsorption chamber and extraction chamber. Water flows into the oil adsorption chamber composed of JT57 liquid filter medium. In this process, oil and grease are absorbed in large quantities and a large number of complex heavy metals, organic substances, TSS, BTEX, PCB and many pollutants in water are extracted.

3 models of marine oil-water separator

There are ten specifications and models of marine oil-water separator * * *. The smallest YWC-1.25(z) marine oil-water separator can be installed on ships below 1,111 tons, and the largest YWC-5 marine oil-water separator can be installed on large ships above 311,111 tons. All oil-water separators must pass the type approval test of China Classification Society. The specific models of oil-water separator are as follows: YWC-1.25(z), YWC-1.5(z), YWC-1.5, YWC-1.1, YWC-1.5, YWC-2.1, YWC-2.5, YWC-3, YWC-4 and YWC-5.
