Overview

As an efficient multiphase separation technology, the Chengde binary cyclone oil-water separator utilizes the density difference between two or more phases under the action of centrifugal force to achieve phase separation. Since the first conical cyclone separator developed by Marse in 1886, cyclone separation technology has been widely used in industries such as petroleum, chemical, food, and papermaking.

Product Details

Chengde binary cyclone oil-water separatorWidely applicable to: crude oil dehydration, oily wastewater treatment, and can also be used in chemical, mechanical, refining, shipping, offshore platforms, and environmental protection industries for wastewater treatment and liquid-liquid separation with positive and negative ratios. It can be used in series at high concentrations.

Cyclone oil-water separator equipmentWorking Principle:
The SL series cyclone oil-water separator relies on the difference in specific gravity between two immiscible liquids and is mainly used to remove over 90% of non emulsified oil from water. The key component of the cyclone oil-water separator, the cyclone tube, consists of a distribution port, a cyclone chamber, a contraction chamber, a tail cone, a tail tube, a bottom flow port, an overflow port, and other parts. The oil-water mixture enters the cyclone tube through the distribution port on the cyclone chamber, and forms a spiral flow under certain pressure difference conditions. Through two-stage contraction of the contraction chamber and tail cone, the fluid is accelerated and a stable centrifugal force field is formed inside the swirl tube. According to Stokes' law, the heavy phase water in the oil-water mixture is thrown towards the inner wall of the cyclone tube in a spiral shape under strong centrifugal force and discharged from the bottom outlet, while the light phase oil gathers at the center of the cyclone tube to form an oil core and is discharged from the overflow outlet, achieving oil-water separation. The centrifugal field generates a centrifugal acceleration of 2000g, so oil-water separation can be achieved within a few seconds. It can be manually operated or automatically controlled.

Chengde binary cyclone oil-water separator, Chengde binary cyclone oil-water separatorInstallation of
During the entire installation process, the equipment should be protected from dirt, dust, and other objects such as metal shavings and bolts
Falling into the device. When connecting external interfaces to device interfaces, attention should be paid to the purpose of each interface on the device.

Cyclone oil-water separator equipmentInstallation requirements
Before installing the equipment, all components, equipment, instruments, valves, etc. should be inspected for damage, and the sealing surfaces should be checked for dirt to ensure timely handling.
The base must be placed firmly and steadily, and the installation must be firm and reliable. Before tightening the flange, the concentricity should be adjusted. During installation, handle with care to avoid unnecessary damage and affect aesthetics. The wiring should be firm and reliable! A backwash pipeline is installed between the inlet and outlet chambers of the equipment to backwash when the oil supply hole is blocked.

Debugging of Chengde binary cyclone oil-water separator

Check if the external interface and device interface are connected correctly. Check whether each valve opens/closes flexibly and whether there is any blockage.
a. When the cyclone is installed (or stopped for a long time) and put into use, the inlet and outlet valves of each process outside the sled should be opened first.
b. Open the backwash valve of the oil discharge chamber, slowly open the inlet valve, outlet valve, and exhaust valve, and close all other valves.
c. Oil containing wastewater with a certain pressure enters the cyclone, and the opening of the inlet and outlet valves is adjusted to ensure the removal of air from the container and manifold, filling the entire chamber of the container with water.
Do not allow water to enter while the outlet valve is closed to prevent damage to the swirl tube inside the container.
d. When liquid overflows from the exhaust pipe, close the exhaust valve and then close the oil discharge chamber backwash valve. Ensure that the equipment runs for 3-5 minutes with the oil discharge valve closed to flush out debris from the container and pipeline, and prevent blockage of the cyclone overflow port.
e. Open the oil discharge valve and valves on the instrument pipeline, and the equipment will enter normal operation.

Chengde binary cyclone oil-water separator manufacturer operation

The operation of the device is in manual control mode. Startup program for cyclone oil-water separator
a. Connect the inlet and outlet valves of various processes outside the sled.
b. Open the backwash valve of the oil discharge chamber, open the exhaust valve, slowly open the inlet valve and outlet valve, and close all other valves.
c. Start the lift pump and allow oily wastewater with a certain pressure to enter the cyclone. Adjust the opening of the inlet and outlet valves to ensure the removal of air from the container and manifold, filling the entire chamber of the container with water.
d. When liquid overflows from the exhaust pipe, close the exhaust valve.
e. Slowly open the oil discharge valve and the equipment enters normal operation.
Adjust the shut-off valves at the outlet and oil outlet of the cyclone to reduce the inlet/outlet water pressure by about 0.35MPa and the inlet/outlet oil pressure by about 0.45MPa.

Cyclone oil-water separator equipmentNotes:
After a certain period of use, if it is found that the effluent quality of the cyclone deteriorates, the oil removal efficiency decreases, or strange noises are emitted inside the equipment chamber, the causes and repair methods are as follows:
The flow rate supplied to the cyclone is inappropriate and should be adjusted accordingly.
Check if the equipment is operating beyond its working range, and if it is operating under normal working pressure and pressure difference. If not, the equipment should be re debugged to make it normal.
Open the cyclone chamber and check for wear or damage to the cyclone chamber, tail cone, etc. If any, replace them immediately. At the same time, check if the O-ring rubber seal is damaged and replace it if necessary.

Cyclone oil-water separator equipmentMaintenance ofSteps:
Before dismantling, it should be confirmed that the inlet and outlet valves of each process of the equipment have been closed, the container and manifold have been depressurized, and the liquid in the container has been completely discharged. Remove the double headed bolts of the container flange connecting the oil discharge chamber and the cylinder, and open the oil discharge chamber. Extract the swirl tube assembly and place it on the prepared fixture.
