The extraction equipment needs to reflux the condensed steam but the reflux is not normal now, please help! ! !

When the steam heats the extraction tank, if the steam is opened slightly larger, it will not be able to flow back normally and the steam will be reversed from the return pipe. Spray out from the drain port of the gas-liquid separation tank. Now I suspect that the small flow rate will cause the liquid in the return port to be vaporized by the steam generated in the tank and prevent it from flowing back. I want to add a U-shaped elbow to the return port and I don't know if this can solve the problem. Also, if all the emptying valves in the entire reflux system are closed to form a closed system, the pressure in the tank will rise. If normal reflux cannot reach 0.07MPa, don’t dare to try again. If a closed system can flow back normally? Can the teacher analyze the reason? What are the constraints? What needs to be done?

Looking at the principle from the process, it mainly deals with the purification of the gas medium in the large tank. The function of your washing liquid tank is to convert the volatile components (components that need to be removed) contained in the liquid phase through the mixed contact of the rising gas of the washing liquid tank, and turn the volatile components into gas and discharge them into the atmosphere. Another possibility is to use the condensed liquid to recover beneficial components in the incoming air through the washing tank. Regardless of the result, the first thing to control is the effective medium being processed, either liquid or gas. Just set one of them as a fixed value, and then gradually increase the amount of medium entering on the other side as needed. For fine operations, you need to set up an online analyzer. For macroeconomics, adjust it to approximately less than the maximum working load of liquid at the drain port. You didn't indicate the specific feed elements. Just a guess for reference. As a final reminder, it is best to control the design parameters in the equipment instruction manual or operating procedures. Does the washer tank have a level gauge? There should be a lot of information that is not reflected in the picture.

First of all, thank you for your reply. The equipment is an ordinary extraction tank, water extraction. Because it operates with a closed lid, the water vapor generated in the tank needs to be condensed and then refluxed into the tank. The instructions do not have such detailed parameters, and it is not known whether the equipment has pipelines arranged according to process requirements.

The cooling capacity of the cooler is insufficient or the steam flow rate is too fast, resulting in a large amount of steam when the steam reaches the gas-liquid separation tank.
