The on-line filter system consists of a filter (the filter element is made of sintered metal) and a back blowing system, wherein the back blowing system consists of a back blowing pipe, a pulse air inlet air bag buffer tank and auxiliary heat mixing (heat preservation and electric heat mixing). The operation logic of the online filtering system is to purge the powder adhered to the filter bag by controlling the quick switch of the electromagnetic valve and the pressure difference between the air bag and the filter.
As the filter is made of sintered metal, the liquefied propylene can liquefy when the temperature of the propylene is low, and the liquefied propylene backflushing filter bag can cause the damage of the filter bag, the temperature of the pulse propylene in the backflushing system is required, and the propylene in the gas bag is required to be always kept in a gaseous state.
In the prior art, in the actual operation process, under the condition of low air temperature, the temperature of the gas bag is often lower than the liquefaction point of propylene, and then a back blowing system is required to be stopped, so that an operator opens a liquid phase line at the bottom of the gas bag to discharge possible liquid-phase propylene so as to enable the gas bag to be filled with gas-phase propylene, and the propylene is wasted. Meanwhile, the common treatment method is to add a heating device at the gas bag, so that the temperature of propylene in the gas bag is kept not lower than the liquefaction temperature of propylene, and the energy consumption is high.
