The heavy fuel separator 112 of two separation chambers, 122 bottom is collected, and condensed water is then discharged from water phase outlet tube 114.But heavy oil
It is close with the density of water, to realize that separation takes a long time.The present embodiment by heavy oil and it is underwater heavy during, then
It is secondary to cool down to it, to increase the density contrast of heavy oil and water, make it easier to separate.It is worth noting that, in this implementation
In example, it is not separated really between the first separation chamber 121 and the second separation chamber 122, the first separation chamber 121 and second
Separation chamber 122 is actually still one complete whole, and the second separation chamber 122 is only to have the effect to cool down again according to it
Fruit, and the differentiation functionally carried out.
Condensation chamber 131 is provided with condensate inlet 132 and condensate outlet 133, and condensate inlet 132 is located at condensation chamber
131 bottom, condensate outlet 133 are located at the top of condensation chamber 131.Condensate liquid moves from the bottom to top, mixed with heavy oil and water
It closes and forms adverse current between object, achieve the purpose that improve cooling effect.
Condensation chamber 131 allows condensate liquid from shell and around shell 110 1 weeks along the circumferential direction setting of shell 110
110 all directions uniformly cool down to the mixing liquid in the second separation chamber 122, increase the effect of separation.
Condenser jacket 130 is made of heat-barrier material.Condenser jacket 130 made of heat-barrier material can prevent the excessive of cold air, make
Heat transmitting can preferably occur between shell 110 for condensate liquid, improve the cooling to mixing liquid in the second separation chamber 122 and imitate
Rate.
The top of shell 110 is provided with respirator 115.Respirator 115 can be used for the air pressure in equilibrium separation room 120,
It avoids the occurrence of since separation caused by negative pressure is unsmooth, flows backwards, or by feelings such as hydrojet, the leakages of the excessive initiation of pressure
Condition.
Second embodiment
A kind of alternating temperature oil water separator 200 is present embodiments provided, referring to shown in Fig. 2, is provided with first embodiment
Alternating temperature oil water separator 100 it is essentially identical, distinguish it is as follows.
In order to further promote cooling efficiency, as shown in Fig. 2, the alternating temperature oil water separator 200 in the present embodiment is also set
It is equipped with condenser pipe 140, condenser pipe 140 includes inlet tube 141, helix tube 142 and outlet tube 143, and helix tube 142 is located at second point
It is arranged from room 122, and around water phase outlet tube 114, the both ends of helix tube 142 connect with inlet tube 141 and outlet tube 143 respectively
Logical, inlet tube 141 and outlet tube 143 run through shell 110.Condenser pipe 140 can be extend into the second separation chamber 122, to second
Mixing liquid inside separation chamber 122 cools down, and is used cooperatively with condensation chamber 131, can greatly increase cooling efficiency.
Further, as shown in Figures 2 and 3, in the present embodiment, alternating temperature oil water separator 200 further includes cyclonic separation
Device 150, cyclone separator 150 are located in the first separation chamber 121, and cyclone separator 150 enters head piece 151 and miscella feed pipe
113 connections, the top of cyclone separator 150 are provided with overflow port 152, and bottom is provided with underflow opening 153.Cyclone separator 150
Preliminary separation can be carried out to oil water mixture, under the effect of centrifugation, light oil is by the overflow port at the top of cyclone separator 150
152 outflows, and heavy oil and water are then flowed out by the underflow opening 153 of 150 bottom of cyclone separator.
Vortex chamber 154 is provided in cyclone separator 150, vortex chamber 154 includes the cylindrical section vortex chamber being located above
1541 and underlying conical section vortex chamber 1542, cyclone separator 150 enter head piece 151 along cylindrical section vortex chamber
1541 tangential direction setting.The oil water mixture tangentially entered helically gestalt movement is entering conical section vortex chamber
After 1542, with being gradually reduced for internal diameter, liquid in rotation speed is gradually accelerated.Since the bore of underflow opening 153 is smaller, so that liquid
Body can not all be discharged from underflow opening 153.Under such circumstances, heavy oil and water are flowed along the cavity wall of vortex chamber 154 by underflow opening 153
Out, and light oil is squeezed to upward at the lower center of pressure, flowed out by overflow port 152, realize the initial gross separation of light oil.
Further, as shown in Figure 2 and Figure 4, the lower section of underflow opening 153 is provided with spoiler 160, spoiler 160 and shell
Body 110 connects, and is spaced and is arranged with the underflow opening of cyclone separator 150 153；It was provided between spoiler 160 and shell 110
Liquid gap 161.The movement velocity of the heavy oil and water that flowed out by underflow opening 153 is very fast, after flowing into the second separation chamber 122, cannot do
Cooling is stopped to sufficient.The setting of spoiler 160 can then play preferable buffer function, heavy oil and water slug to spoiler
On 160, after being blocked deceleration, then by cross liquid gap 161 be flowed into the second separation chamber 122, adequately cooled down, Jin Erti
High score from effect.
