Description

Technical Field

[0001] This utility model relates to the technical field of oil and gas recovery, and specifically to an oil and gas recovery condensation treatment device. Background Technology

[0002] The principle of oil and gas condensation recovery is to use refrigeration technology to convert hydrocarbons in oil and gas from the gas phase to the liquid phase, thereby realizing oil and gas recovery. The specific process includes three stages: pre-cooling, shallow cooling and deep cooling. The equipment and operating conditions required for condensation recovery are relatively simple, and the purity of the recovered substances is relatively high.

[0003] Condensation recovery is one of the common methods for treating oil and gas. However, existing condensation recovery devices have low stability during continuous operation. During the condensation recovery process, the generation of condensate can affect the subsequent oil and gas condensation effect. Generally, the condensation tank is of fixed size, but the amount recovered varies. It is difficult to adjust and separate the condensation tank according to the treatment requirements, which will affect the efficiency of oil and gas separation and may even prevent a small amount of oil and gas from being separated and discharged. Summary of the Invention

[0004] The purpose of this invention is to provide an oil and gas recovery and condensation treatment device to solve the above-mentioned defects caused by the prior art.

[0005] An oil and gas recovery and condensation treatment device includes a treatment chamber, a condensation chamber, and a compressor. A liquid pump is installed on one side of the treatment chamber, and a condenser is installed on the outside of the treatment chamber. A discharge pipe is connected through one side of the treatment chamber. An adjustment mechanism is installed inside the condensation chamber to divide the condensation chamber into separation chambers of different areas, thereby facilitating the cooling and separation of the gas-liquid mixture. A purification mechanism is installed inside the condensation chamber to filter the liquid separated from the gas before discharge, thereby preventing impurities in the liquid from clogging the pipes and affecting the stability of the device operation.

[0006] Preferably, the adjusting mechanism includes a condenser box, an evaporator box, finned plates, a guide groove, and an isolation pad. The evaporator box is located inside the condenser box, the finned plates are located inside the evaporator box, the guide groove is located inside the condenser box, isolation pads are symmetrically connected to both sides of the evaporator box, and the input end of the compressor is connected to one side of the evaporator box.

[0007] Preferably, the condenser box is connected to both sides of the evaporator box via symmetrically opened guide grooves.

[0008] Preferably, the purification mechanism includes a condenser housing, a filter element, a screw, an internal threaded seat, and a pressure relief valve. The filter element is disposed inside the condenser housing, and screws are symmetrically disposed on the outer side of the filter element. The bottom end of the screw is connected to an internal threaded seat, and the internal threaded seat is symmetrically welded to the inside of the condenser housing.

[0009] Preferably, the filter element is connected to the condenser housing via a through-connected screw.

[0010] Preferably, the condenser is connected to the other side of the condenser via the input end of a liquid pump connected to one side.

[0011] Preferably, the condenser is connected to the evaporator via a compressor connected to the input end.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. By utilizing the lateral displacement of the evaporator within the condenser, the standard space of the condenser is divided into condensation spaces of varying sizes. This allows for rapid cooling of the gas-liquid mixture within smaller spaces, preventing the inability to achieve gas-liquid separation due to small oil and gas volumes in large spaces. Simultaneously, a set of evaporators cools the separated spaces. During operation, the liquid discharged from the capillary tube enters the evaporator, where the low-temperature, low-pressure liquid evaporates and absorbs heat, resulting in a very low surface temperature of the evaporator. This cooling capacity is then transferred to the condenser, lowering its temperature.

[0014] 2. A groove is provided at the bottom of the condenser housing to filter the condensed oil using a filter element. This prevents impurities in the oil and gas from clogging the discharge pipe, improving the efficiency of oil and gas treatment and effectively protecting the environment from pollution.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown, an oil and gas recovery condensation treatment device includes a treatment chamber 1, a condensation chamber 6, and a compressor 13. A liquid pump 2 is installed on one side of the treatment chamber 1, and a condenser 3 is installed on the outer side of the treatment chamber 1. A discharge pipe 4 is connected through one side of the treatment chamber 1. An adjustment mechanism 5 is installed inside the condensation chamber 6, which divides the condensation chamber 6 into separation chambers of different areas to facilitate the cooling and separation of the gas-liquid mixture. A purification mechanism 11 is installed inside the condensation chamber 6, which filters the liquid separated from the gas before discharge, thereby preventing impurities in the liquid from clogging the pipes and affecting the stability of the device operation.

[0024] In this embodiment, the adjusting mechanism 5 includes a condenser box 6, an evaporator box 7, finned plates 8, a guide groove 9, and an isolation pad 10. The evaporator box 7 is disposed inside the condenser box 6, the finned plates 8 are disposed inside the evaporator box 7, and the guide groove 9 is disposed inside the condenser box 6. The isolation pads 10 are symmetrically connected to both sides of the evaporator box 7, and the input end of the compressor 13 is connected to one side of the evaporator box 7. The isolation pads 10 block the gap at the connection between the condenser box 6 and the evaporator box 7 to prevent oil and gas from overflowing from the side into the other part of the cooling chamber.

[0025] In this embodiment, the condenser box 6 is connected to both sides of the evaporator box 7 through symmetrically opened guide grooves 9, which guide and limit the two sides of the evaporator box 7.

[0026] In this embodiment, the purification mechanism 11 includes a condenser box 6, a filter element 12, a screw 14, an internal thread seat 15, and a pressure relief valve 16. The filter element 12 is disposed inside the condenser box 6, and the screw 14 is symmetrically disposed on the outer side of the filter element 12. The bottom end of the screw 14 is connected to the internal thread seat 15, and the internal thread seat 15 is symmetrically welded to the inside of the condenser box 6.

[0027] In this embodiment, the filter element 12 is connected to the condenser box 6 through a through-connected screw 14, and the outer side of the filter element 12 is symmetrically connected through symmetrically arranged screws 14.

[0028] In this embodiment, the condenser 6 is connected to the other side of the condenser 6 via the input end of the liquid pump 2 connected to one side. The liquid pump 2 is used to extract the liquid and inject it back into the isolated condenser 6.

[0029] In this embodiment, the condenser 3 is connected to the evaporator 7 via the compressor 13 connected to the input end. The compressor 13 is used to circulate the refrigerant for cooling, thereby completing the internal refrigeration process of the evaporator 7.

[0030] In practical applications, this oil and gas recovery and condensation treatment device includes the following tasks:

[0031] Step 1: Before use, first pull the evaporator 7 according to the range of oil and gas filtration at one time. Using the guide groove 9 opened inside the condenser 6, the evaporator 7 is moved laterally. Then, the evaporator 7 divides the standard space of the condenser 6 into condensation spaces of different areas. The gap at the connection between the condenser 6 and the evaporator 7 is blocked by the isolation pad 10 to prevent oil and gas from overflowing from the side into another part of the cooling chamber.

[0032] Step 2: Compressor 13 draws gaseous refrigerant from evaporator 7 and pressurizes it into condenser 3. The high-pressure gaseous refrigerant liquefies in condenser 3, undergoing heat exchange (releasing heat), which is carried away by the air outside the evaporator 1. The high-pressure liquid refrigerant is depressurized by the expansion valve, and the low-pressure liquid refrigerant vaporizes in evaporator 7, absorbing heat. The cooled air near evaporator 7 is transferred to the interior of condenser 6, where the gaseous refrigerant is again drawn away by compressor 13 and pumped into condenser 3, thus creating a closed-loop circulation of the refrigerant.

[0033] Step 3: During the condensation process, the oil and gas temperature is reduced from the ambient temperature to about 5°C, causing most of the water vapor to condense into water and be removed. The oil and gas temperature is then cooled to about -35°C, causing 70-80% of the hydrocarbon components to liquefy. At the same time, a liquid pump 2 is installed on the outside to inject a portion of the condensed oil from the condensation tank 6 to the other side of the condensation tank 6. The condensation tank 6 filters the oil through the internal filter element 12.

[0034] Step 4: When the filter element 12 needs to be replaced, rotate the screw 14 so that the bottom end of the screw 14 rotates and separates from the outer side of the internal thread seat 15. Use the pressure relief valve 16 to relieve the pressure during the separation process to avoid excessive pressure affecting the discharge safety of the condenser box 6.

[0035] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
