The utility model relates to water-treatment technology field, relates in particular to a kind of porous plate water cap active carbon filter with anti-active carbon powder leakage function.
Background technology
At present, water resource is deficient day by day, and the water quality deterioration phenomenon is on the rise, and especially serious is microorganism and organic matter is to the pollution of water quality.In recent years, in service at the Subcritical Units in thermal power plant, supercritical unit, ultra supercritical unit, total organic carbon TOC has caused people's great attention in the boiler feedwater to the influence of boiler and steam turbine.Therefore, in GB/T 12145-2008 " thermal power generation unit and apparatus of steam power plants steam quality " the boiler feedwater quality standard TOC index has been done strict qualification.
Make the TOC index reach standard, just must remove microorganism and the organic matter in the water.Removal microorganism and organic method mainly contain biochemical process, chemical oxidization method and physical absorption and hold back method at present.Biochemical process mainly is organic matter, water and the carbon dioxide that microorganism is become less molecule with the larger molecular organics biochemical degradation, reduces total phosphorus and ammonia-nitrogen content.Chemical oxidization method can only sterilization with the larger molecular organics oxidation Decomposition is become small organic molecule.More than two kinds of methods all can not satisfy the qualification of Boiler water Feeding System system subsequent processing device (like counter-infiltration, ion-exchanger) to entering organic matter of water content, more can not meet the restriction of boiler feedwater to total organic carbon TOC content.
Remove small organic molecule and mainly hold back method by physical absorption at present, method equipment is held back in the physical absorption of ripe removal small organic molecule now has ultrafiltration, weak acid positive resin interchanger and active carbon filter.
Wherein,, can only remove colloid and big molecular melting organic matter, can't remove the small organic molecule of solubilised state because ultrafiltration apparatus receives the restriction of fenestra size.Though a little less than positive resins exchange device can remove the small organic molecule of solubilised state, the back recovery of losing efficacy needed soda acid, can pollute environment, and the unusual complicacy of its operation and control, auxiliary water ratio is big, cost of investment is also than higher.
Thereby, remove at present that solubilised state small organic molecule aspect is employed at most, the best equipment of treatment effect is active carbon filter.Active carbon filter not only can be removed the solubilised state small organic molecule, can also remove clear water through contained chlorine residue after the oxidation processes, can for follow-up Boiler water Feeding System equipment (like counter-infiltration, ion-exchanger) qualified influent quality be provided effectively.But active carbon filter can contain a certain amount of small particle powder active carbon at initial operating stage (after the backwash) with in a period of time after changing filtrate in the water outlet.After these small particle powder active carbons get into reverse osmosis unit; Can cause the dirt of reverse osmosis membrane passage stifled, negative issues such as the rising of operating pressure, producing water ratio descend, the pressure drop rising of system, membrane flux reduction, its destruction to reverse osmosis membrane can't use conventional method to recover.If the small particle powder active carbon gets into ion-exchanger, also can stop up the adsorption hole of exchanger resin, the exchange capacity of ion-exchanger is descended, shorten the cycle of operation, cause ion-exchanger backwash and regeneration frequent, increase soda acid consumption and self water consumption.The main cause that above-mentioned condition occurs is, the discharging device of active carbon filter is generally porous plate water cap at present, or quartz sand thickness, and its space is bigger, causes active carbon to leak easily.
Concrete as, the slit of active carbon filter porous plate water cap is generally 0.25 millimeter, tiny active carbon powder can pass through this slit smoothly.If the water cap slit of porous plate is reduced, then the water flow of active carbon filter can reduce, and does not reach the requirement of exerting oneself.
Therefore, those skilled in the art is devoted to develop a kind of porous plate water cap active carbon filter with anti-active carbon powder leakage function.
The utility model content
Because the above-mentioned defective of prior art, the utility model technical problem to be solved provides a kind of porous plate water cap active carbon filter with anti-active carbon powder leakage function.
For realizing above-mentioned purpose, the utility model provides a kind of porous plate water cap active carbon filter with anti-active carbon powder leakage function, comprises filter body, is provided with porous plate water cap and active carbon layer in the said filter body; Also be provided with water inlet, delivery port on the said filter body, just wash discharge outlet, backwash discharge outlet, backwash water inlet; Be provided with fine sand layer between said active carbon layer and the said porous plate water cap.
Preferably, the fine sand particle diameter of said fine sand layer is between the 0.3-0.5 millimeter.
Preferably, the loading height of said fine sand layer is between the 400-600 millimeter.

The beneficial effect of the utility model is:
The porous plate water cap active carbon filter with anti-active carbon powder leakage function of the utility model; Owing between active carbon layer and porous plate water cap, be provided with fine sand layer; Solved the phenomenon that active carbon filter in use leaks Powdered Activated Carbon, its principle is that mechanical grading is held back.
Because the particle diameter of the fine sand that is loaded is less and particle is more even; Loading height is lower, and after accumulation was filled into filter, intergranular space was little and many; Huge surface area is arranged; Resistance to current is also little, under the situation that need not increase influent pressure force-summing device Inlet and outlet water pressure reduction, just can solve the active carbon filter water outlet and carry the carbon dust problem.Simultaneously can get better water distribution performance, shorten just washing the time of active carbon filter, obtain better water-saving result.
