Description

Technical Field

[0001] The utility model relates to a crude oil detection device, more specifically, to a filtered water circulation condensation device for testing crude oil emulsified water. Background Art

[0002] The analysis of emulsified water in crude oil requires the use of a condensation device. Currently, the most common experimental heating devices on the market are water bath and oil bath heating. Common condensers include straight tube internal structure condensers, uniform spherical internal structure condensers, and uniform spiral internal structure condensers. Since the crude oil taken out of the storage tank contains emulsified water and a small amount of gas, and the density of crude oil is lower than that of water, it is easy to boil over and expand during the heating process, and spray out from the condenser outlet, which poses certain safety hazards.

[0003] Typical condensing units have poor condensation performance, likely due to internal structural issues with the condenser tubes and excessively fast water flow, resulting in poor heat exchange and incomplete cooling. These units are unable to recycle the condensate, connecting the condenser tube inlet through a tap and discharging it directly into the pool at the outlet, resulting in a significant waste of fresh water resources. Furthermore, the tap opening and closing are difficult to control, and excessive water flow can easily cause the hoses at the condenser tube inlet and outlet to detach. Water flowing onto electrical wires can cause short circuits and safety accidents. Furthermore, poor water quality can cause moss to grow on the walls of the condenser tube's internal heat exchange structure, and impurities in the water can clog the pipes. During experiments, the water in the tank continues to heat up, affecting the condensation effect and preventing continuous, high-frequency use. Currently, condensing units with filtration capabilities on the market are expensive, complex, and require high maintenance costs. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1 As shown, the filtered water circulation condensation device for crude oil emulsified water testing includes a heating base 1 and a round-bottom flask 2. The round-bottom flask 2 is located above the heating base 1. The upper part of the round-bottom flask 2 is connected to a moisture receiver 3. The upper part of the moisture receiver 3 is connected to a condenser 4. The upper part of the condenser 4 is provided with a water outlet 7, and the lower part of the condenser 4 is provided with a water inlet 17. The water outlet 7 is connected to a water circulation cooling box S through a first hose 5.

[0024] The water circulation cooling box S comprises a box body 6, a pair of cover plates 9 are provided on the top of the box body 6, a primary filter plate 10, a secondary filter plate 11 and a circulating water pump 12 are provided in the box body 6, a temperature sensor 13 and a water level sensor 14 are provided on the outer wall of the box body 6, and a cooler 15 is provided on the lower surface of the bottom plate of the box body 6.

[0025] The circulating water pump 12 is connected to the water inlet 17 via a second hose 5S.

[0026] like Figure 2As shown, the condenser 4 includes an outer tube body 41 and an inner tube body 42. The inner tube body 42 includes a plurality of spherical heat exchange shells 421 connected in series. The heat exchange shells 421 are interconnected, and the size of the heat exchange shells 421 gradually increases along the flow direction of the steam.

[0027] The minimum diameter of the heat exchange spherical shell 421 is equal to one third of the outer cylindrical diameter of the outer tube body 41 , and the maximum diameter of the heat exchange spherical shell 421 is equal to four fifths of the outer cylindrical diameter of the outer tube body 41 .

[0028] Since the internal spherical heat exchange structure at the end close to the steam inlet has a smaller diameter and a smaller spacing, the cooling specific surface area is increased, which is conducive to the condensation and reflux of high-boiling-point raw materials into the reaction system. The internal spherical heat exchange structure at the end far from the steam outlet has a larger diameter, a larger spacing, and a larger coil diameter, which reduces the cooling specific surface area and avoids excessive condensation and reflux of low-boiling-point by-products into the reaction system. The steam with different boiling points creates a potential energy difference, which can fully separate the low-boiling-point steam.

[0029] Since the cooling surface of the spherical heat exchange structure is larger than that of the straight cylindrical heat exchange structure, more distillate is retained during distillation. It is suitable for vertical continuous long-term distillation or reflux equipment, and can effectively control the solution from being ejected from the top of the condenser.

[0030] It should be noted that the cooler 15 is a semiconductor refrigeration plate. Of course, the cooler 15 can also be other refrigeration structures.

[0031] In addition, the heating base 1 is provided with a power adjustment knob 1S, which can adjust the heating power of the heating base 1.

[0032] In addition, the primary filter plate 10 and the secondary filter plate 11 are detachably arranged in the box body 6, which is convenient for replacement and maintenance.

[0033] It should be noted that a large-pore filter sponge is provided in the primary filter plate 10 , and a 10D filter sponge is provided in the secondary filter plate 11 .

[0034] In addition, the primary filter plate 10 and the secondary filter plate 11 are rotatably arranged in the box body 6, so that the user can adjust the angle of the filter plate conveniently.

[0035] The working mode of the filtered water circulation condensation device for crude oil emulsified water testing is described below.

[0036] When the user turns on the heating base 1, the oil, water, and solvent oil mixture in the round-bottom flask 2 is heated, causing the water-in-oil emulsion to rupture and release water. Because the solvent oil has a stronger polarity, it can extract water from the crude oil system. Due to the different boiling points of the components, the water vaporizes along with the solvent oil and cools and condenses in the condenser 4. The water in the condenser 4, carrying heat energy, flows out of the water outlet 7, passes through the primary filter plate 10 and the secondary filter plate 11, and enters the housing 6. This filters out most solid impurities, fully maintaining the cleanliness of the circulating water, extending the water recycling cycle, and conserving water resources. The water in the housing 6 is pumped out by the circulating water pump 12 and flows to the water inlet 17 of the condenser, thus forming a water circulation loop.

[0037] During this process, the temperature sensor 13 monitors the temperature inside the water-circulating cooling tank S in real time. When the temperature reaches the maximum limit, the temperature sensor 13 issues an alarm. Furthermore, the water level sensor 14 monitors the water level inside the water-circulating cooling tank S in real time. When the water level is too low, the water level sensor 14 issues an alarm. If the water temperature exceeds a preset value, the cooler 15 activates to cool the water, thereby increasing the operating life of the condensing unit.

[0038] The filtered water circulation condensation device for crude oil emulsion water testing has many advantages:

[0039] 1. The multi-layer filter plate and circulating water pump can ensure that the experimental water can be recycled; the water level sensor can ensure the experimental water quantity; the semiconductor refrigeration cooler can ensure that the condensing device can be used continuously for a long time, ensuring the safety of the experiment while realizing automatic operation;

[0040] 2. The special structure of the condenser 4 can prevent the crude oil system from spraying out of the condenser during continuous heating, thereby improving safety;

[0041] 3. More than 90% of the components of the overall device can be freely disassembled and assembled, which is convenient, fast and easy to carry, with low subsequent maintenance costs. It can be used for high-frequency emulsified water experiments on shale oil sites, breaking away from the limitations of on-site water sources.

[0042] Obviously, the embodiments described above are only part of the embodiments of the present application, rather than all the embodiments. The drawings provide preferred embodiments of the present application, but do not limit the patent scope of the present application.
