Steam of different pressure enters into the chemical production device through the pipeline and carries out the thermal cycle in-process, and most steam can be because of heat absorbed and reduce temperature and pressure, becomes liquid by the gaseous state, becomes steam liquid return. The steam returns liquid and all has certain pressure, if in returning the steam of different pressure in the system to the liquid and collecting a closed container, will cause low pressure steam because return liquid outlet pressure too high and mobility reduces or can't flow, causes the unable circulation of steam, and the heat exchange process can't go on, leads to the chemical industry reaction process can't last going on. Therefore, the steam liquid return water tank for collecting steam liquid return in actual production is set to be a normal-pressure container.
