The working principle of the utility model is as follows:
The liquid swirl in a stationary hydrocyclone is produced by the high-velocity flow of liquid at a certain pressure. The produced water of the oil field enters the cylindrical vortex section along the tangential direction and flows spirally along the axial direction of the cyclone tube to enter the concentric necking section, and due to the change of the section, the narrow cross section area accelerates the liquid to 30000r/min, so that a strong centrifugal force for separating oil and water is formed, and the liquid is accelerated and kept in the conical section in order to compensate the loss of the centrifugal force and the friction force. Due to the density difference of water and oil, the centrifugal force acting on the water phase with higher density makes the water swirl along the conical pipe wall; the oil phase with lighter density is collected in the center to form a low-pressure oil core, the outer water ring passes through the parallel tail section and is discharged from the purified water outlet, and the separation process of the oil water in the cyclone tube is not more than 2 seconds.
The separation performance of the cyclone is mainly influenced by the particle size of the oil phase, the liquid temperature and the density difference of the oil-water liquid phase to be separated. The mechanism of hydrocyclone separation can be expressed in terms of stokes law. This law is expressed in terms of net separation force (F N) in the cyclonic separation of spherical oil particles, as the difference between the centrifugal force (F) produced by the swirling flow and the shear force (F S) on the moving oil particles: f N=F-FS
Wherein F- -centrifugal force, # W - -density of water, ρ u - -density of oil, a- -angular acceleration, d- -particle size.
FS=3π·μW·v·d----------(2)
Wherein F S - -shear force, mu W - -kinematic viscosity of water, v- -radial velocity of oil particles.
Thus, the net separation force F N is expressed as:
Formula (3) shows that F N may be affected by four factors, namely particle size, angular acceleration, density difference between liquid phases, and viscosity of the water continuous phase. Among the four factors, angular acceleration is easier to control. Theoretically, the greater the angular acceleration, the higher the separation effect. In practice, however, excessive speeds can result in shearing or crushing of the oil particles and unstable flow, which can reduce separation performance.
The separation performance of a hydrocyclone is related to the following factors:
Particle diameter of oil particles: the larger the oil particles, the better the separation effect. If the particle size of the oil particles is less than 5. Mu.m, separation is difficult; when the particle diameter of the oil particles is more than 20. Mu.m, separation is easy. Therefore, if the process is reasonably designed (e.g., a positive displacement pump or a low-speed lift pump is selected), the throttling, pressure drop and other shearing forces of the cyclone inlet on the produced water can be eliminated, thereby maximizing the oil particle size.
Temperature: the viscosity of water can be reduced by increasing the temperature, and the separation performance of the cyclone can be improved by easily passing oil particles through the water phase.
Density difference: deoiling depends on the relative density difference between the oil and water, and in general, the density difference should be greater than 50kg/m 3, the greater the density difference, the higher the separation effect.
Inlet oil content: with the increase of the inlet oil content, the particle size of the oil particles is correspondingly increased, which is beneficial to improving the separation performance. Therefore, the relative increase of the oil content of the inlet has little influence on the quality of the effluent. But the inlet oil content should be below 2000mg/L.
Surface tension: surface tension exists in the interface of two incompatible liquids. Lower surface tension can reduce the shearing resistance of the oil particles, so that the oil particles are easier to break. The higher surface tension becomes "sticky" oil particles, making them less prone to breakage or coalescence with other oil particles into larger oil particles.
Gas: since the residence time of the gas/liquid in the hydrocyclone is extremely short, equilibrium cannot be reached and therefore no significant effect is produced in the cyclone separation process. Hydrocyclones can treat liquids with a gas content of 20%.
Chemical agents and solid particles: surfactants can affect the interfacial properties of the oil-in-water oil particles and the stability of the emulsion. The detergent molecules and organic salts are concentrated on the interfaces of oil particles after being mixed with the oil-in-water emulsion because of carrying electrostatic charges, so that the same polarity discharge is carried out on all dispersed oil particles, and the oil particles are mutually repelled and can not be coalesced. Solids such as scale and iron sulfide can strengthen the interfacial film and stabilize the emulsion.
The process of the utility model is calculated as follows:
The fixed hydrocyclone effectively separates oil from water by means of centrifugal force. As shown in fig. 3, its inlet pressure and inlet shape is the rotation of the liquid, the flow rate of which is controlled by the pressure drop across the cyclone. The differential pressure determines the maximum throughput of the hydrocyclone and is calculated as follows:
The pressure drop Δp 0 (oil drain) between the inlet and the oil drain is:
ΔP0=P-P0-------------(4)
Wherein P is the raw water inlet pressure, MPa, P 0 is the oil discharge outlet pressure and MPa.
The pressure drop Δp w (drain) between inlet and outlet is:
ΔPw=P-Pw------------(5)
P w - -purified water outlet pressure, MPa.
At a constant flow and drain ratio of 1.5%, Δp 0 is about 2 times Δp w. Thus, given a pressure drop, the maximum throughput of the cyclone is dependent on the pressure drop Δp 0. The following describes two concepts of oil drainage ratio and oil removal efficiency.
The ratio of the oil discharge amount to the total water inlet amount is the oil discharge ratio eta 0:Q0
Wherein Q-total produced water inlet flow, m 3/h,Q0 -total oil discharge, m 3/h.
Although the oil extraction ratio refers to the oil content, the oil content is generally less than 10% by volume, and the balance is water. Under the condition that the oil content in water is less than 1 percent by volume. In order to achieve the best operating condition, the oil discharge ratio of the deoiling type hydrocyclone should be kept in the range of 1% -2%. If the oil content of the inlet water is more than 1%, the oil discharge ratio should be increased in order to maintain the separation efficiency.
The pressure difference ratio is the ratio of the pressure drop of the inlet and the oil drain port members to the pressure drop of the purified water outlet, and can be expressed as:
Only maintaining a constant ratio of Δp 0 and Δp w ensures an optimal constant oil drain ratio.
The oil removal efficiency determines the quality of the purified water, expressed as:
Wherein C- - -inlet oil content, mg/L, C W - - -purified water outlet oil content, mg/L.
At a certain inlet pressure, the hydrocyclone operational flow rate should be maintained within a range in which the degreasing efficiency is maintained at an optimum constant condition.
The maximum flow rate of the hydrocyclone is controlled by the pressure drop between the inlet and the oil drain. If the inlet flow of the cyclone exceeds this maximum flow range, the flow rate becomes too high, resulting in a lower core pressure that cannot be discharged from the drain. Thus, the oil removal efficiency is lowered due to insufficient amount of the oil drain.
If the inlet flow rate of the cyclone is lower than the minimum flow range, the flow rate becomes too small, and as a result, the cyclone centrifugal force cannot be achieved, and thus the oil-water separation effect cannot be achieved.
The process control of the utility model is as follows:
There are various control methods of the system according to the system constitution of the hydrocyclone. The method specifically comprises the following steps:
(1) Maximum purge water flow control
The maximum purified water flow rate of the hydrocyclone is generally determined by the pressure of the incoming buffer tank lift pump and the difference between the raw water inlet pressure and the outlet purified water pressure of the hydrocyclone. The maximum flow of the cyclone is limited by the minimum back pressure acting on the water outlet. The maximum flow can be limited by installing a restrictor at the hydrocyclone inlet or by bypass.
(2) Minimum purge water flow control
① Indirect control of
If the pressure difference between the inlet and the outlet of the hydrocyclone is lower than the preset pressure difference, the flow control valve is closed; and opening the flow control valve when the water level of the buffer tank rises or the pressure difference between the inlet and the outlet of the cyclone reaches a preset value.
② Direct control of
And closing the flow control valve if the flow of the cyclone falls below a preset limit.
(3) Control of oil discharge flow
① If the ratio of Δp 0 to Δp w remains constant, the drain flow rate decreases proportionally if the water flow rate decreases.
② Flow control valve control
The oil discharge control valve and the flow control valve at the inlet of the cyclone are controlled by parallel signals in the same way as the flow control valve at the outlet of the purified water.
③ On-off or flash control
The purified water outlet flow control valve and the oil discharge control valve are both in on/off positions, and the back pressure of the oil discharge port is set by the downstream throttle. In practical application, the flow rate of the oil drain port tends to be relatively stable, and is about 2% of the rated purified water outlet flow rate. The method is simple and effective, can be adjusted on site, and is suitable for stable flow conditions or low-pressure and low-flow working conditions.
(4) Throttle control
Typically, the turndown ratio between the maximum and minimum flow rates of the hydrocyclone is 7:1. As long as the water outlet of the hydrocyclone is not lower than the minimum flow of the hydrocyclone, the hydrocyclone can still work stably.
The structural design of the utility model is as follows:
(1) Design input
The treatment amount (m 3/h), the oil content (mg/L) of the incoming water and the oil content of the incoming water are lower than 2000mg/L. The oil content (mg/L) of effluent, the design pressure (MPa), the design temperature (DEG C), the external dimension, the material of a cyclone tube and others.
(2) Process calculation
And calculating and determining the diameters of the water inlet, the water outlet and the oil drain opening according to the treatment capacity, then determining the diameters and the number of the swirl tubes, determining the diameter of the tank body according to the swirl tubes, and comprehensively calculating the volume of each cavity.
Principle:
① Since the difference in density between the two liquid phases of oil and water is small, a strong rotational centrifugal force needs to be generated to ensure radial movement.
② To obtain a strong centrifugal force and avoid excessive pressure drop, a small diameter of the cyclone is required, but a large aspect ratio is required to ensure a sufficient residence time.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
