Regarding the installation of a filter screen at the outlet of the urea melting pump
Thread Content
The urea granulation system uses large-particle fluidized bed granulation; to prevent foreign substances from entering the nozzle, a filter screen is installed at the flange before the nozzle in the urine pipeline. After prolonged operation, the filter screen becomes clogged, causing the pressure at the nozzles to drop; in such cases, it is necessary to stop the granulation process and circulate the fluid through the evaporation system in order to remove and clean the filter screen. Could the filter be installed at the outlet of the urea melting pump? When the filter becomes clogged, the pump could be reversed to clean the clogged filter, thereby avoiding any disruption to the operation of the granulation system.
Do you mean installing a filter on the main pipe of the pump? You might as well run the pipeline a couple of times and add a pressure difference display
I want to move the filter to the pump outlet, in front of the pump outlet valve
Cleaning during the granulation operation cycle is sufficient; it depends on whether your urine is too dirty or if the filter mesh is too fine
