　　三、純冷凝法油氣回收裝置工作原理

　　3、 Working principle of pure condensation method oil and gas recovery device

　　純冷凝"法油氣回收工藝是利用制冷技術(shù)，先將油氣逐級(jí)從常溫冷卻到-25~-110度左右(針對(duì)不同揮發(fā)氣體可設(shè)定不同的冷凝溫度)，使油氣逐級(jí)液化回收。整機(jī)系統(tǒng)通過(guò)以上過(guò)程不斷循環(huán)，從而達(dá)到油氣連續(xù)冷卻分凝回收，同時(shí)確保揮發(fā)油氣達(dá)標(biāo)排放。

　　The "pure condensation" oil and gas recovery process utilizes refrigeration technology to first cool the oil and gas from room temperature to around -25~-110 degrees Celsius (different condensation temperatures can be set for different volatile gases), allowing the oil and gas to liquefy and recover step by step. The entire system continuously circulates through the above process to achieve continuous cooling and condensation recovery of oil and gas, while ensuring that volatile oil and gas meet emission standards.

　　制冷原理:利用多機(jī)復(fù)查制冷技術(shù),為油氣系統(tǒng)提供多梯度連續(xù)冷場(chǎng)。制冷系統(tǒng)工作時(shí)由壓縮機(jī)排出的高溫高壓制冷劑氣體進(jìn)入冷凝器被冷凝成高壓過(guò)冷液體，經(jīng)膨脹閥節(jié)流降壓變成低溫低壓的汽液兩相混和物進(jìn)入蒸發(fā)器，制冷劑在其內(nèi)蒸發(fā)并吸收通過(guò)蒸發(fā)器的油氣的熱量，使流經(jīng)蒸發(fā)器的油氣得以降溫，利用物質(zhì)在不同溫度下的蒸氣壓差異，通過(guò)降溫使油氣組分達(dá)到過(guò)過(guò)飽和狀態(tài)冷凝成液態(tài)直接回收，冷凝后的低濃度氣體進(jìn)入吸附系統(tǒng)吸附處理。同時(shí)制冷劑充分汽化后再被壓縮機(jī)吸入壓縮室進(jìn)入下一輪循環(huán)。整機(jī)系統(tǒng)通過(guò)以上過(guò)程不斷循環(huán)，從而達(dá)到油氣連續(xù)降溫回收的目的。油氣分凝原理:不同沸點(diǎn)的制冷劑直接蒸發(fā)吸收油氣熱量，使油氣中多種組分溫度分梯度降至凝點(diǎn)以下，通過(guò)油氣換熱分離器的有效分離實(shí)現(xiàn)油氣分凝回收。

　　Refrigeration principle: Utilizing multi machine re examination refrigeration technology to provide a multi gradient continuous cooling field for the oil and gas system. The high-temperature and high-pressure refrigerant gas discharged by the compressor during the operation of the refrigeration system enters the condenser and is condensed into a high-pressure supercooled liquid. It is then throttled and depressurized by the expansion valve to become a low-temperature and low-pressure mixture of vapor and liquid, which enters the evaporator. The refrigerant evaporates inside and absorbs the heat of the oil and gas passing through the evaporator, cooling the oil and gas flowing through the evaporator. By utilizing the difference in vapor pressure of the substance at different temperatures, the oil and gas components reach a supersaturated state and are condensed into liquid for direct recovery. The condensed low concentration gas enters the adsorption system for adsorption treatment. At the same time, the refrigerant is fully vaporized and then sucked into the compression chamber by the compressor to enter the next cycle. The entire system continuously cycles through the above process to achieve the goal of continuous cooling and recovery of oil and gas. Principle of oil and gas separation and condensation: Refrigerants with different boiling points directly evaporate and absorb the heat of oil and gas, causing the temperature gradient of various components in the oil and gas to drop below the condensation point. Through effective separation by an oil and gas heat exchanger separator, oil and gas separation and recovery are achieved.
