Description

TECHNICAL FIELD

[0001] The application relates to the oil and gas recovery technical field, in particular to a condensate conveying device for oil and gas recovery. BACKGROUND

[0002] In the process of oil and gas exploitation, storage, transportation and sales, oil and gas volatilization is always a thorny problem. According to relevant data, the oil and gas volatilization loss rate can reach 0.8%-1.2% in the process of oil product circulation from the refinery to the terminal gas station, which not only causes great energy waste, but also pollutes the atmospheric environment due to the emission of hydrocarbon compounds in the volatilized oil and gas, and seriously aggravates the greenhouse effect and photochemical smog pollution.

[0003] For example, the patent with the publication number CN208927629U specifically discloses a condensation and adsorption type oil and gas recovery treatment device, which comprises a main body, a base, a controller, a multi-evaporator cascade refrigeration system, an activated carbon adsorption device, a heat dissipation area, an oil and gas backflow port, an air inlet, an exhaust cylinder, a control panel and an emergency stop button. The oil and gas is recovered and treated by combining the condensation method and the adsorption method of the recovery treatment device, and the structure design is reasonable, and the oil and gas recovery utilization rate is high.

On the one hand, the temperature control of the traditional condensation system is single and rigid, and it is difficult to flexibly adjust according to the actual working conditions, which often leads to energy waste or incomplete condensation. For example, the fixed condensation temperature cannot adapt to complex working conditions with different oil and gas concentrations, compositions and flow rates, so that part of the oil and gas escapes and is not recovered. Meanwhile, in the above-mentioned patent, the heat dissipation area and the main body are designed in an integrated manner, so that the heat dissipation area and the like may be blocked by dust after long-term use, and the integrated design makes it difficult to maintain and clean these components.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] like Figures 1-3 As shown, this application provides a condensate conveying device for oil and gas recovery, including a main body 1, a support 11 fixedly installed on the main body 1 for supporting the main body 1, and four sets of support legs 12 fixedly installed on the support 11. The support legs 12 are in contact with the ground, and an oil and gas return port 13, an air inlet 14 and an exhaust pipe 15 are fixedly connected to the main body 1.

[0024] The condensate conveying system for oil and gas recovery includes an induced draft fan, a dual-channel condenser, a precooling box, a primary shallow cooling box, a secondary intermediate cooling box, and a tertiary deep cooling box. Under the pressure boosting action of an external induced draft fan, the condensate first enters a channel in the oil and gas heat exchanger, and then sequentially enters the precooling box, the primary shallow cooling box, the secondary intermediate cooling box, and the tertiary deep cooling box. The precooling box is designed at 10-20℃ to remove some water from the oil and gas. The primary condensing temperature is designed at 5℃ (adjustable) to recover high-boiling-point components from the oil and gas. The secondary condensing temperature is designed at -20℃ (adjustable) to recover components with C5 or higher from the oil and gas. The tertiary condensing temperature is designed at -70℃ (adjustable) to recover components with C4 or higher from the oil and gas. Under this gradient low-temperature condition, most components in the oil and gas undergo phase changes sequentially, achieving liquefaction and recovery.

[0025] Further, the first condensation is 5℃, the second condensation is -20℃, and the third condensation is -70℃, and three sets of refrigeration units are designed to be in the mode of being thrown and cut, and users can flexibly select according to actual needs on site;

[0026] Moreover, the oil-gas heat exchanger adopts a double-channel parallel structure, and can alternately perform refrigeration and defrosting, so as to ensure continuous refrigeration operation of the device. Each stage adopts a new technology of controlling double-channel evaporators by a single set of unit, and high-temperature refrigerant vapor discharged by a refrigeration compressor is used for heat pump defrosting, so that the defrosting is fast, and the condensation treatment of oil-gas is not affected by defrosting, and the device is economical, energy-saving, safe and reliable.

[0027] In the present application, the air inlet pipeline and the exhaust cylinder 15 of the whole machine system are provided with oil-gas temperature, flow, pressure and concentration detection;

[0028] Working principle: Under the pressure boosting effect of an external air blower, oil-gas first enters a certain channel in the oil-gas heat exchanger, and then enters a pre-cooling tank, a first-stage shallow cooling tank, a second-stage medium cooling tank and a third-stage deep cooling tank in turn.

[0029] In the pre-cooling tank, the temperature is controlled at 10-20℃, and part of the water in the oil-gas is removed in the process. Then, the oil-gas enters the first-stage shallow cooling tank, and the first-stage condensation temperature is set to 5℃ (which can be adjusted according to actual conditions), so that the high-boiling-point components in the oil-gas are phase changed and recovered at this temperature. Then, the oil-gas enters the second-stage medium cooling tank, and the second-stage condensation temperature is -20℃ (which can also be adjusted), so that the components above C5 in the oil-gas are liquefied and recovered. Finally, the oil-gas enters the third-stage deep cooling tank, and the third-stage condensation temperature reaches -70℃ (which can be adjusted), so that the components above C4 in the oil-gas are recovered. Through such a gradient low-temperature condition setting, most of the components in the oil-gas are phase changed in turn, so as to realize the effect of liquefied recovery.

[0030] The oil-gas heat exchanger in the device adopts a double-channel parallel structure, and can alternately perform refrigeration and defrosting operation, so as to ensure that the device can continuously operate. Moreover, each stage adopts a new technology of controlling double-channel evaporators by a single set of unit, and high-temperature refrigerant vapor discharged by a refrigeration compressor is used for heat pump defrosting. This defrosting method is not only fast and efficient, but also does not affect the condensation treatment of oil-gas, and has the advantages of being economical, energy-saving, safe and reliable.

[0034] And the clamping plate 23 is fixedly installed on both sides of the filter plate 22, and the clamping plate 23 has a gap with the filter plate 22, so that the filter plate 22 is clamped on the frame 21 through the gap between the clamping plate 23 and the filter plate 22, and the positioning plate 24 is fixedly installed on the side surface of the clamping plate 23, and the positioning plate 24 is provided with a notch groove (not marked in the figure);

[0036] Working principle: the filter plate 22 in the heat dissipation mechanism 2 can be clamped on the frame 21 through the gap between the clamping plate 23 on both sides of the filter plate 22 and the filter plate 22, and the rotating shaft 27 installed on the mounting seat 26 is rotated to be clamped in the notch groove of the positioning plate 24, and the butterfly nut 28 is tightened, so that the bottom surface of the butterfly nut 28 abuts against the upper surface of the positioning plate 24, to fix the filter plate 22, ensure the normal operation of the heat dissipation mechanism 2, prevent foreign matters from entering the device to affect the heat dissipation effect and the normal work of other components, and when the filter plate 22 needs to be cleaned, the filter plate 22 can be slid from the slot in the frame 21 by holding the handle 25, and then taken out from the opening on the top to be cleaned, and after cleaning, the filter plate 22 can be reinstalled according to the above fixing steps to maintain the stable operation of the heat dissipation mechanism 2, and thus ensure the continuous, stable and efficient work of the entire condensate conveying device for oil gas recovery.
