SUMMARY OF THE INVENTION

The purpose of the present invention is to solve the above-mentioned problems in the prior art, and provide a condensation recovery tank with a simple structure, a better separation effect of the gas phase and the liquid phase of the gas flow, and a higher condensation recovery rate.

The object of the present invention can be achieved through the following technical solutions: a condensation recovery tank, comprising a condenser, the upper end of the condenser is provided with a filter with an exhaust joint, and the lower end of the condenser is provided with a low temperature The liquid accumulation tank, a gas-liquid separator is arranged between the low-temperature liquid accumulation tank and the condenser, and an air inlet joint is arranged on the gas-liquid separator. A flow resistance device for the flow of air, the air flows into the air inlet joint, and the kinetic energy of the air flow is reduced through the flow resistance device to form a gas-liquid separation, the liquid flows into the low-temperature liquid accumulation tank, the gas flows to the condenser, and the gas is cooled by the condenser and converted again. For the liquid to flow into the low temperature liquid accumulation tank, the remaining gas passes through the filter and is discharged from the exhaust joint.

The condensation recovery tank is mainly composed of a condenser, a filter, a gas-liquid separator and a low-temperature liquid accumulation tank. Each part is manufactured separately, and then assembled into a whole, which is convenient for production and manufacture. The airflow through the flow resistance device continuously and repeatedly impacts the flow resistance element in the flow resistance device to reduce the kinetic energy of the airflow, thereby reducing the entrainment ability of the airflow, and then formed by centrifugal separation, surface adsorption, natural deposition, differential penetration, etc. Gas-liquid separation effect; the gas is cooled by the condenser and converted into liquid again, the liquid is captured by the condenser and the filter and then flows down into the low-temperature liquid accumulation tank again, and the liquid recovery effect is better; the gas-liquid separator is equipped with a flow resistance device, The airflow through the flow resistance device can effectively slow down the flow rate, so that the airflow can be fully separated, the gas phase and liquid phase separation effect of the airflow is better, the structure stability is high, and the use is convenient.

In the above-mentioned condensation recovery tank, the gas-liquid separator includes an outer pipe body and an inner pipe body, the outer pipe body is sleeved outside the inner pipe body, and the inner pipe body and the outer pipe body are spaced and matched with each other. An annular partition plate is arranged on the top between the outer pipe body and the inner pipe body, and the air inlet joint is located in the tangential direction of the outer pipe body. The annular baffle is located at the top of the interval between the outer pipe body and the inner pipe body, and the annular baffle, the outer pipe body and the inner pipe body are fixedly connected into an integral structure, with stable structure and long service life.

The air flow enters tangentially on the outer pipe body from the air inlet joint, which is convenient to generate annular air flow. The guide plate makes the air flow spirally inclined upward to impact the annular partition plate, and cooperates with the blind holes on the annular partition plate, which can quickly and effectively weaken the kinetic energy of the airflow flow. , reducing the ability of the airflow to carry liquid; the guide plate is spaced along its circumference. With the continuous increase of the intake air flow, the flow area of the airflow expands downward. When the airflow area exceeds the lower part of the guide plate, the airflow is blocked. It is divided into upper and lower parts, and the upward airflow continues to move in a circular motion; the downward airflow spirals down along the interval between the outer tube body and the inner tube body; due to the faster airflow speed, the airflow can obtain greater upward movement after hitting the guide plate Therefore, the relatively slow airflow is more likely to be squeezed downward to form a downward airflow; the speed of the downward airflow is smaller, the airflow contains less energy, and the ability to carry liquid is weaker, and part of the liquid in the airflow will naturally deposit. to the surface of the filter. At the same time, during the circular motion of the airflow, under the action of centrifugal force, the relatively heavier liquid will move to the outside of the annular airflow under the action of centrifugal force, and will eventually converge and be adsorbed on the inner wall of the outer tube, so as to achieve the effect of gas and liquid separation. .

The contact distance is longer, the impact on the filter screen layer is small, and it can provide more penetration opportunities and time for the liquid, thereby improving the separation effect of the filter screen; the purpose of setting the filter screen layer is: first, the filter screen layer It is used to isolate the air flow and the liquid in the low-temperature liquid accumulation tank, so as to prevent the liquid in the liquid accumulation tank from contacting the high-speed moving air flow; secondly, after the outer downward airflow collides with the filter screen layer, it turns under the blocking effect of the filter screen layer. , and the liquid penetrates the filter screen layer, resulting in the effect of gas-liquid separation; thirdly, the filter screen layer has the function of cooling and capturing the evaporation of the liquid under the filter screen layer; finally, it prevents the airflow from impacting the liquid accumulation in the low-temperature liquid accumulation tank the liquid level to improve the accuracy of the oil glass indication.
