Anti-crushing device of resin filter

Abstract

The invention discloses an anti-crushing device of a resin filter, which comprises a water-distributing spiral paddle and a water-distributing plate. The water-distributing spiral paddle is arranged at the bottom of the resin filter and is used for shunting to make water flow rise spirally, and the water-distributing plate is arranged between the water-distributing spiral paddle and a resin filler layer and is provided with a plurality of water-distributing holes. Water can be distributed uniformly, the flow area can be increased, and the impact on resin caused by water flow through the resin filler layer can be reduced. Meanwhile, due to common effects of the water-distributing spiral paddle and the water-distributing plate, the direction of water flow can be changed, so that the water flow can rise spirally, and the direction of water flow impact applied vertically upwards on resin particles can be changed, so that the water flow impact can be applied on the resin particles in the horizontal tangential direction. Resin layers can be expanded upwards layer by layer, the combination of the water flow impact and resin extrusion effects can be weakened, the possibility of resin crushing can be reduced, and the service life of resin can be prolonged.

Description

technical field [0001] The invention relates to an anti-shattering device for a resin filter. Background technique [0002] Resin filters are widely used in the purification field of ion exchange technology. At present, during the use of resin filters, due to mechanical external force, repeated transformation, degradation of polymer molecules, regeneration, backwash extrusion and other reasons, the strength of the resin is easy become weak and cause fragmentation. Resin crushing will have a serious impact on the operating conditions of the ion exchanger, mainly as follows: 1) It can increase the resistance of the equipment and greatly reduce the outflow speed of reclaimed water; 2) The resin powder will flow into the next process of the water treatment system with the water , Deteriorating the water quality of the effluent; 3) Resin crushing reduces the periodic water production of the exchanger. Judging from the situation of resin scrapping in recent years, resin scrappin...

Problems solved by technology

[0002] Resin filters are widely used in the purification field of ion exchange technology. At present, during the use of resin filters, due to mechanical external force, repeated transformation, degradation of polymer molecules, regeneration, backwash extrusion and other reasons, the strength of the resin is easy weaken to break

Resin crushing will have a serious impact on the operating conditions of the ion exchanger, mainly as follows: 1) It can increase the resistance of the equipment and greatly reduce the outflow speed of reclaimed water; 2) The resin powder will flow into the next process of the water treatment system with the water , deteriorating the effluent water quality; 3) Resin crushing reduces the cycle water production of the exchanger

Judging from the situation of resin scrapping in recent years, the scrapping of resin due to high crushing rate accounts for about 80% of the total amount of scrapping resin, and the annual replenishment rate of resin due to crushing increases by about 5%, resulting in a substantial increase in operating costs
