Description
TECHNICAL FIELD
[0001] The utility model relates to crude oil processing technical field, concretely is a kind of crude oil demulsifier dosing device. BACKGROUND
[0002] The mechanism of demulsifier is phase transfer-reverse deformation mechanism, phase inversion occurs after adding demulsifier, i.e. the surfactant opposite to the type of emulsion formed by emulsifier can be generated, and this kind of demulsifier reacts with hydrophobic emulsifier to generate complex, so that the emulsifier loses emulsifying property. In the processing of crude oil, a special crude oil demulsifier is usually used to destroy the emulsifier on the surface, so as to meet the production requirements in later period.
[0003] In crude oil production, the demulsifier is mostly prepared by an integrated dosing device for proportioning, and then the prepared demulsifier is poured into crude oil for production. During the mixing and stirring process, a large amount of foam is easily generated, which causes waste of raw materials and is not conducive to accurate measurement of the demulsifier. UTILITARIAN CONTENT
[0004] Therefore, the utility model provides a crude oil demulsifier dosing device to solve the technical problems in the background art.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a crude oil demulsifier dosing device, comprising a mixing tank, a medicine storage tank and a speed reducer are installed on the top of the mixing tank, a communication pipe is installed at the bottom of the medicine storage tank, and the communication pipe extends through the mixing tank to the inside of the mixing tank, a stirring assembly is connected to the output end of the speed reducer, the stirring assembly comprises a stirring rod, an extruder is connected to the outer surface of the stirring rod through a communication seat, a rotating sleeve is connected to the bottom end of the stirring rod, a water storage tank is connected to one side of the mixing tank, a water pipe is connected to the bottom of the water storage tank, and one end of the water pipe is connected to the rotating sleeve.
[0006] Further, a conveying pipe is connected to the bottom of the mixing tank, and a metering pump is installed on the outer surface of the water pipe, the communication pipe and the conveying pipe.
[0007] When the crude oil demulsifier is diluted, the demulsifier in the medicine storage tank enters the mixing tank through the communication pipe, the water in the water storage tank is transported to the stirring assembly through the water pipe, and the water flows out of the extruder to mix with the demulsifier. The mixed liquid is diluted by stirring, and then transported to the wellbore through the conveying pipe to emulsify the crude oil. The amount of water and demulsifier entering the mixing tank is accurately controlled by the metering pump, so as to avoid inaccurate manual proportioning.
[0008] Further, a heating rod is installed in the water storage tank.
[0009] By adopting the technical scheme, the water in the water storage tank is heated by the heating rod, and the water temperature is maintained at a certain temperature, so that the water and the demulsifier are mixed, and the mixed liquid is appropriately heated. When the demulsifier emulsifies the crude oil, appropriate heating can reduce the viscosity of the crude oil, thereby accelerating demulsification and improving the demulsification efficiency of the demulsifier.
[0010] Further, the control panel is mounted on one side of the water storage tank, and the metering pump, the reduction motor and the heating rod are electrically connected with the control panel.
[0011] By adopting the technical scheme, the staff sets the program in the control panel, controls the delivery amount of the three metering pumps, the rotation speed of the reduction motor and the heating temperature of the heating rod, so that the staff does not need to closely monitor the device, realizes automatic operation and reduces the labor intensity of the staff.
[0012] Further, the stirring rod and the connecting seat are hollow.
[0013] By adopting the technical scheme, when mixing, the reduction motor output end drives the stirring shaft to rotate slowly, and under the driving of the metering pump on the water pipe, the warm water is delivered to the stirring rod through the water pipe, and finally flows out from the extruder to mix with the demulsifier, so that the warm water and the demulsifier are fully contacted, and the mixed liquid is stirred by the stirring assembly, so that the water and the demulsifier are mixed more fully.
[0014] Further, the extruder is in a semi-elliptical shape and is hollow inside.
[0015] By adopting the technical scheme, under the driving of the reduction motor output end, the stirring rod drives the extruder to rotate. Because the blockage pressure at the inlet of the extruder and the accelerated flow inside the extruder will generate turbulence, these turbulences collide in the circular motion of the stirrer, enhancing the mixing motion. At low rotation speed, the medium is completely degassed, thereby reducing bubble formation and avoiding affecting the metering when mixing the demulsifier.
[0016] Further, the extruder is provided with two groups, each group containing three extruders, and the three extruders are distributed in a ring array.
[0017] By adopting the technical scheme, under the driving of the reduction motor output end, the stirring rod drives the extruder to rotate. Through multiple extruders, the mixed liquid is stirred in multiple levels, so that multiple extruders simultaneously dilute different levels of demulsifier, thereby accelerating the dilution speed.
[0018] Further, the outer surfaces of the medicine storage tank and the water storage tank are provided with observation windows, and the observation windows are provided with scale patches.
[0019] Through the observation window, the worker can observe the demulsifier and the water temperature in the storage tank and the water storage tank, and through the scale patch, the worker can more accurately determine the specific value of the remaining amount, thereby facilitating the worker to add the material.
[0020] To sum up, the utility model mainly has the following beneficial effects:
[0021] 1、The utility model discloses a stirring assembly, water pipe, metering pump, control panel, observation window and scale patch are arranged, and the specific process is as follows: the demulsifier is added to the storage tank through the storage tank, and the water is added to the water storage tank through the water pipe, and the demulsifier and the water are mixed in the mixing tank, and the demulsifier and the water are mixed in the mixing tank.
[0022] 2、The utility model discloses a heating rod and metering pump are set up, the water in the water storage tank is heated through the heating rod, and the water temperature is kept at a certain temperature, so that the water and the demulsifier are mixed, and the mixed liquid is heated appropriately when the demulsifier is mixed, and when the demulsifier is emulsified, the viscosity of crude oil is reduced, so that the demulsification is accelerated, and the demulsification efficiency of the demulsifier is improved.
