[0002] The mechanism of the crude oil demulsifier is the phase transfer-inverse deformation mechanism. After adding the demulsifier, a phase transformation occurs, that is, a surfactant that can form an emulsion type opposite to that of the emulsifier can be generated. This type of demulsifier acts with the hydrophobic emulsifier to form a complex, so that the emulsifier loses its emulsifying performance. The mechanism of collision and breaking of the interfacial film. Under the conditions of heating or stirring, the demulsifier has many opportunities to collide with the interfacial film of the emulsion, or adsorb on the interfacial film, or displace and replace some surface active substances, thereby breaking the interfacial film, greatly reducing its stability, and causing flocculation and coalescence to demulsify.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present utility model provides a device for adding a crude oil demulsifier, comprising:

[0034] A crude oil demulsifier reaction kettle 1 is provided with a dosing mechanism on it. It should be noted that the crude oil demulsifier is slowly added through the dosing mechanism to ensure the quality of production;

[0035] The dosing mechanism includes a power motor 2, a power round box 3, a housing 6, a crude oil demulsifier addition hopper 7, a first dosing pipe 12 and a second dosing pipe 13;

[0036] The power motor 2 is fixedly arranged at the top of the crude oil demulsifier reaction kettle 1, and the output end of the power motor 2 is fixedly connected to the power round box 3. It should be noted that the power round box 3 is located inside the crude oil demulsifier reaction kettle 1, and the top of the power round box 3 is in contact with the inner wall of the top of the crude oil demulsifier reaction kettle 1;

[0037] The housing 6 is fixedly installed on the inner wall of the top of the crude oil demulsifier reaction kettle 1, the crude oil demulsifier addition hopper 7 is fixedly installed at the top of the crude oil demulsifier reaction kettle 1, both the first dosing pipe 12 and the second dosing pipe 13 are fixedly installed on the power round box 3, and a plurality of inlet holes 10 are opened on the outer side of the power round box 3. It should be noted that the plurality of inlet holes 10 are arranged at equal intervals in a ring on the outer side of the power round box 3.

[0038] Through the above dosing mechanism, first, the crude oil demulsifier is added into the two crude oil demulsifier addition hoppers 7. The power motor 2 is started and the solenoid valve 8 is opened. The crude oil demulsifier in the crude oil demulsifier addition hopper 7 will be added into the flow channel on the housing 6, and then enter the inside of the power round box 3 through the inlet holes 10, and be added into the inside of the crude oil demulsifier reaction kettle 1 through the first dosing pipe 12 and the second dosing pipe 13 on the power round box 3. When the power round box 3 rotates, it will drive the first dosing pipe 12 and the second dosing pipe 13 to rotate. In this way, the crude oil demulsifier discharged from the first dosing pipe 12 and the second dosing pipe 13 will be evenly added to the inside of the crude oil demulsifier reaction kettle 1. In addition, the length of the second dosing pipe 13 is greater than the length of the first dosing pipe 12, further improving the uniformity of adding the crude oil demulsifier.

[0039] Specifically, the dosing mechanism further includes a stirring main shaft 4, a first stirring branch blade 5, and a second stirring branch blade 9. The stirring main shaft 4 is fixedly installed at the bottom end of the power round box 3. The first stirring branch blade 5 is fixedly installed on the stirring main shaft 4, and the second stirring branch blade 9 is fixedly installed outside the power round box 3.

[0040] With the above structure, when the power round box 3 rotates, it will drive the stirring main shaft 4 and the second stirring branch blade 9 to rotate. The second stirring branch blade 9 will initially stir the crude oil demulsifier in the housing 6, and the first stirring branch blade 5 will further stir the crude oil demulsifier in the crude oil demulsifier reactor 1, making the reaction of the crude oil demulsifier more complete and improving the product quality.

[0041] Specifically, a flow channel is opened at the top end of the housing 6, and the flow channel is communicated with the inlet hole 10. It should be noted that this facilitates the crude oil demulsifier to flow into the interior of the power round box 3 through the flow channel and the inlet hole 10.

[0042] Specifically, a round hole is opened at the bottom end of the housing 6, and a sealing gasket 11 is fixedly arranged in the round hole. The power round box 3 is in sealed contact with the sealing gasket 11. It should be noted that in this way, when the power round box 3 rotates, the sealing performance between the power round box 3 and the housing 6 can be ensured.

[0043] Specifically, an electromagnetic valve 8 is installed on the crude oil demulsifier dosing hopper 7, and the crude oil demulsifier dosing hopper 7 is communicated with the interior of the housing 6. It should be noted that the crude oil demulsifier is added into the two crude oil demulsifier dosing hoppers 7, and then the electromagnetic valve 8 is opened to carry out the dosing work of the crude oil demulsifier.

[0044] Specifically, both the first dosing pipe 12 and the second dosing pipe 13 are communicated with the interior of the power round box 3, and the length of the second dosing pipe 13 is greater than that of the first dosing pipe 12. It should be noted that since the lengths of the first dosing pipe 12 and the second dosing pipe 13 are different, when dosing, the crude oil demulsifier can fall from different positions above the interior of the crude oil demulsifier reactor 1, improving the dosing uniformity.

[0045] Specifically, a discharge pipe 14 is fixedly arranged on the crude oil demulsifier reactor 1, and a valve is installed on the discharge pipe 14. The second stirring branch blade 9 is located inside the housing 6 and above the inlet hole 10. It should be noted that the second stirring branch blade 9 can initially stir the crude oil demulsifier in the housing 6 and further stir the crude oil demulsifier in the crude oil demulsifier reactor 1, making the reaction of the crude oil demulsifier more complete, making the hydrolysis and emulsification stratification of the polymerization liquid more complete, and improving the product quality.

[0046] Working principle:

[0047] Step S1: Add the crude oil demulsifier into two crude oil demulsifier adding hoppers 7. When it is necessary to add the crude oil demulsifier, start the power motor 2 and open the solenoid valve 8. The power motor 2 drives the power circular box 3 to rotate, and the power circular box 3 drives the inlet hole 10 to rotate. The crude oil demulsifier in the crude oil demulsifier adding hopper 7 will be added into the flow channel on the housing 6, and then enter the inside of the power circular box 3 through the inlet hole 10, and be added into the inside of the crude oil demulsifier reaction kettle 1 through the adding pipe 12 and the adding pipe 13 on the power circular box 3. When the power circular box 3 rotates, it will drive the adding pipe 12 and the adding pipe 13 to rotate. Thus, the crude oil demulsifier discharged from the adding pipe 12 and the adding pipe 13 will be evenly added into the inside of the crude oil demulsifier reaction kettle 1. In addition, the length of the adding pipe 13 is greater than that of the adding pipe 12, which further improves the uniformity of adding the crude oil demulsifier;

[0048] Step S2: When the power circular box 3 rotates, it will drive the stirring main shaft 4 and the stirring branch blade 9 to rotate. The stirring branch blade 9 will preliminarily stir the crude oil demulsifier in the housing 6. The stirring main shaft 4 drives the stirring branch blade 1 to rotate, and the stirring branch blade 1 further stirs the crude oil demulsifier in the crude oil demulsifier reaction kettle 1, making the reaction of the crude oil demulsifier more thorough, making the polymerization liquid hydrolyze and emulsify and stratify thoroughly, and improving the product quality.

[0049] The above has introduced in detail a crude oil demulsifier adding device provided by the present utility model. Specific embodiments are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
