It can be seen from the figure that the transformation of the original deaerator is very convenient. That is to use the shell head part of the original deaerator head to remove all the water drenching plate or spray packing parts in the original deaerator head, keep the lower steam inlet plate, and then install the liquid steam network and water grate at a certain position above the lower steam inlet plate, and then seal and fix the annular pressure plate to prevent water vapor short circuit in future operation.
After the joint between the head and the cylinder is uncoupled and welded into the membrane stripper, the other parts of the pipe port are connected according to the transformation scheme provided. It is completed and put into operation after passing the acceptance.
In the process of transformation, the height should be appropriately changed according to the actual situation. Generally, the diameter of the deaerator head is not increased, but only increased or welded according to the original height.
deaerator Ordering instructions
1. Order a complete set of new rotary membrane deaerator, provide the following parameters:
: output of deaerator
: deaerator height, cylinder diameter and wall thickness
: working pressure and temperature of feed water of deaerator
2. The following data shall be provided for technical transformation of old deaerator:
: height, cylinder diameter and wall thickness of existing deaerator
: working pressure and temperature of feed water of existing deaerator
