Briefly describe the principle and function of the oil-water separator

The main working principle of the oil-water separator is to apply the theory of fluid mechanics. At the moment when the oily sewage flows continuously and synchronously (the same speed of oil and water is relative turbulence), the oil beads collide continuously with the kinetic energy when the sewage flows at high speed, thus accelerating the movement, so that oil and water with different specific gravity can be separated, layered and separated, and finally the purpose of oil-water separation can be realized.

the main function is to remove the water in diesel oil, so as to reduce the failure of the fuel injector and prolong the service life of the engine. The principle is mainly based on the density difference between water and fuel oil, using the principle of gravity sedimentation to remove impurities and moisture, and there are separation elements such as diffusion cone and filter screen inside. The oil-water separator also has other functions, such as preheating fuel to prevent wax deposition and filtering impurities. Function of oil-water separator

Before using the oil-water separator, the operation and management personnel of the turbine should understand the requirements for the start-up, operation and maintenance of the separator according to the instructions for the use and maintenance of the product.

1. Inspection and preparation for start-up

1. Before using the oil-water separator equipment for discharge, the consent of the bridge should be obtained

2. Check the line installation of the oil-water separator and whether the steering of the supporting pump is normal

3. Supply water to the oil-water separator, and open the top air valve. Let the air escape

4. Check that there is no leakage on the water inlet and outlet system of the oil-water separator

2. Matters needing attention in operation

1. Adjust the opening of the valve of the drainage pipeline to keep the pressure in the separator. To facilitate the drainage of dirty oil in the separator

2. Observe whether the indicating instruments such as pressure gauge and thermometer are normal

3. Observe the treated drainage water quality and the working condition of the oil concentration alarm

4. After the discharge, continue to inject clean water for 1.5 min, and clean the separator

5. Close the inlet and outlet valves after stopping the pump to avoid the loss of clean water in the cylinder. Reduce the oxidation and corrosion of the inner wall

6. Every time the oil-water separator is used, it should be recorded in the oil record book

3. Maintenance

1. Clean the filter regularly, open the drain valve at the bottom of the separator, and remove the sediment and impurities deposited in the lower part

2. Clean the internal separation elements of the separator in time, and avoid cleaning the inner wall and elements of the separator with cleaning agents

3. When there is a fault. The reason should be found out and the failed coalescer should be replaced in time

4: internal anticorrosion

1. Internal anticorrosion of small oil-water separator

When crude oil was just mined from underground, the temperature was relatively high, and crude oil (oil, water and gas mixture) was very corrosive due to the existence of pickling gas. How to prevent corrosion at high temperature has always been a topic. After 2115, high-temperature anticorrosion polymer composite material has become a major method of high-temperature anticorrosion, and it has been trusted by enterprises as an efficient, cheap and high-performance oil-water separator protection technology. Polymer composites have obvious advantages in this respect, such as superior high-temperature performance to general coating technology, superior corrosion resistance to coatings with the same temperature resistance, and wear resistance, which are incomparable to other coating systems.

2. Internal anticorrosion of large-scale oil-water separator

The oil-water separator is made of ordinary steel. If it is not sprayed, it will be corroded quickly, because crude oil contains sulfur, water, etc., and the temperature is relatively high, and it is flowing, impact and corrosion, so ordinary coating is not good. If it is made of stainless steel, the cost is too high. The application technology of < P > high-temperature resistant polymer composite materials of Meijiahua series in the United States is very special. Generally, after spraying in 1 hours, the top is 1.4mm, and the rest is 1.4mm(55 mils) from top to bottom.

The thickness of the coating can make it more wear-resistant. Other coatings need to be sprayed to this thickness, which requires 2-3 layers, or even more, for more than 5 days. This is not only a question of construction efficiency, but also a question of quality and service life. What is the working principle of catering oil-water separator and hotel oil-water separator? Where can I find an oil-water separator?

I don't know the details. You can visit Jinlijie official website! Ask customer service! How does the oil-water separator work?

The compressed air oil-water separator is a gas-liquid separation system using Esquel proprietary technology. Cyclone and stainless steel wire mesh are organically combined to catch fog. Its principle is the combination of centrifugation and coalescence. The inner coalescence filler is OCr18Ni9, and the gas-water separation efficiency is ≥99.9%, which has a thorough effect of gas-liquid separation and avoids the secondary evaporation of water. Compared with cyclone separation, it has better separation effect, lower use cost, no need of maintenance and replacement and long service life than filter gas-liquid separator. This series of products has a large amount of water and oil removal and a wide range of applicable working conditions.

Different densities of oil and water rotate at the same time and are thrown to different planes for separation

1: oily sewage is sent to the oil-water separator by the sewage pump, and after passing through the diffusion nozzle, large oil droplets float on the top of the left oil collection chamber

2: sewage containing small oil droplets enters the corrugated plate coalescer at the lower part, where the oil droplets are polymerized into larger oil droplets to the right oil collection chamber

3: sewage containing smaller oil droplets passes through the fine filter, and impurities in the water are discharged, and then enter the fiber polymerizer in turn, so that the small oil droplets are polymerized into larger oil droplets and larger oil droplets.

4: After separation, the clean water is discharged through the discharge port, and the dirty oil in the left and right oil collection chambers is automatically discharged through the electromagnetic valve, while the dirty oil separated from the fiber polymerizer is discharged through the manual valve.

The oil-water separator consists of three parts: a pressure reducing valve and an oil mist sprayer. The filter

the pressure reducing valve is used to adjust the pressure

the oil mist device is used to pump a small amount of oil into the equipment

the filter is used to filter the water in the air

When the compressed air containing a large amount of oil and

water solid impurities enters the separator, it spins down along its inner wall, resulting in the centrifugal effect, which makes the oil and water separate out from the

steam flow and flow down the wall to the bottom of the oil-water separator, and then it is filtered by the filter element. Because the

used in the filter element is made of three kinds of fiber filter materials: coarse, fine and superfine, it has high filtration efficiency and low resistance

. When the gas passes through the filter element, it is firmly adhered to the filter fiber due to the blocking of the filter element, inertial collision, van der Waals force between molecules, electrostatic attraction

and vacuum suction, and gradually increases into droplets, which are dripped under the action of gravity. There is generally nothing wrong with discharging

from the drain valve, except that the water separated from the oil-water separator freezes in winter, which will cause the energy supply gas path to be blocked

and affect the transmission of braking force, resulting in the reduction of the braking force of the brake and the insufficient braking force caused by the air leakage of the oil-water separator.

The ultimate goal of the oil-water separator is not to separate grease, but to completely decompose the grease to form harmless substances and discharge them into the urban pipe network. Now,
