According to the resin trap, resin trapped on a filter screen can be discharged without dismantling a filter cartridge, and working efficiency is improved.

Description

Resin catcher

Technical field

The present invention relates to a kind of resin catcher, especially a kind of device for capturing the water resin particle.

Background technology

The supplementary feed in fuel-burning power plant is processed and condensed water processing main technique is ion exchange technique, and the carrier of water treatment is ion exchange resin.When carrying out online water treatment with resin, when second-rate (insufficient strength), the hydraulic pressure disturbance large (particularly high pressure disturbance) of resin, when the resin barrel is damaged, resin can enter whole water system, normal operation to other equipment of this system impacts, and therefore needs the installing resin catcher.Resin catcher (resintrapper) is to capture the device of taking the resin particle of ion-exchanger with water out of.Resin catcher mainly is exactly near the little a lot of filter screen of aperture ratio resin of water system pipeline installation ion-exchanger etc. is equipped with the equipment outlet of resin, and has washing function.When resin through out-of-date, can be caught by filter screen interception, simultaneously, automatically wash by the front and back differential pressure, the resin that catches is given off system.

Existing resin catcher comprises filter cylinder, at filter cylinder water-in and water outlet is set, and in cartridge interior filter screen is set,, can observe filter screen by the visor on the filter cylinder and collect how many resins, so that in time cleaning is changed.But filter screen is changed in each cleaning, all needs technique to suspend, and filter cylinder is taken apart, has reduced working efficiency.In addition, the barrel shell of resin catcher generally all adopts common carbon steel sheet in the middle of the prior art, in use because corrosion can cause reduce work-ing life.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, a kind of resin catcher is provided, can realize not taking apart filter cylinder, can discharge the resin that captures on the filter screen, improved working efficiency; And the shell ring of this resin catcher has good erosion resistance.

According to technical scheme provided by the invention, described resin catcher, comprise shell ring, at the inner filter core of installing of shell ring, the flange of shell ring one end is fixedly connected with blind flange, the flange of the shell ring the other end is fixedly connected with the second flange of big or small first end, and the concentric reducer the other end arranges the first flange, sets out the mouth of a river at the first flange; End away from water outlet on described shell ring connects water inlet pipe, on the nozzle flange of water inlet pipe water-in is set; Connect blow-off pipe at the middle part of described shell ring, at the three-flange of the blow-off pipe mouth of pipe sewage draining exit is set; It is characterized in that: described shell ring adopts corrosion-resistant steel to make, the composition of this corrosion-resistant steel is: C:0.05 ~ 0.1%, Si:0.05 ~ 1%, Mn:0.1 ~ 1%, P≤0.02%, S≤0.01%, Al:0.005 ~ 0.05%, N≤0.005%, Cr≤0.5%, Cu:0.01 ~ 0.1%, W:0.01 ~ 0.1%, Sn:0.005 ~ 0.05%, all the other are Fe, and unit is mass percent.

Between the second flange of the end flange of described shell ring and big or small first end, retaining ring is set.

At described shell ring visor is set.

Resin catcher of the present invention can realize not taking apart filter cylinder, can discharge the resin that captures on the filter screen, has improved working efficiency; The present invention adopts corrosion-resistant steel as the material system of shell ring, has good erosion resistance.

Description of drawings

Fig. 1 is structural representation of the present invention.
