Abstract
The utility model relates to a cationic layer mixing bed with variable procedure. An intermediate outlet device of a header branch pipe type or other types is arranged on the slight upper part of the boundary surface of a bottom mixed resin layer and an upper cationic resin layer. When the utility model is in operation, the treated water entering from the top can be exhausted from the bottom after passing the cationic resin layer and the mixed resin layer one after another downward, and can be also exhausted by the intermediate outlet device after only passing the cationic resin layer. Except for having the advantages of ordinary cationic layer mixing bed, the utility model can also easily realize the operation of the ammonization of the single cationic resin layer when the water quality of entering water is better, so that the frequency of regenerative operation and the operating cost are greatly reduced. The utility model is mainly used for the condensate treatment of a power station.
Description
The utility model belongs to water-treatment technology field, particularly a kind of variable flow formula Cationic layer mixing bed.
Cationic layer mixing bed claims sun to mix bed (seeing " fuel-burning power plant purification of water quality " P235 page or leaf that April nineteen ninety, hydraulic and electric engineering press published) again.It is mainly used in condensed water is handled.In Cationic layer mixing bed, be positioned at the positive resin layer above the hybrid resin layer, not only can play the effect that thereby corrosion product mitigate corrosion product pollutes negative resin in its mixed downstream resin layer in the filtering water at first, also because it has removed the ammonia in the water, reduced the pH value of water, thereby improved the ion-exchange condition of negative resin in its mixed downstream resin layer, and and then reached the effect that improves hybrid resin layer effluent quality and prolong the time cycle of operation (see for details " Electric Design water technology " 1997 fourth phase 37～44 pages).In addition, under the condition that positive resin layer exists on have, inhomogeneous (negative resin is more on top if mix for bottom yin, yang resin, and positive resin is more in the bottom), can bad influence not arranged to this serviceability of mixing bed yet, because in this case, this equipment is similar to and is moving by placed in-line positive and negative, the multiple bed system mode of sun.But with the Cationic layer mixing bed that the Hydrogen mode is moved, the cycle is shorter, and regeneration times is frequent, working cost is high.As adopt the ammonia type to mix a bed mode and move, though can overcome above-mentioned shortcoming, the technical qualification harshness promptly need be made regenerator with highly pure bases, adopts peracid, alkali regenerant consumption and the positive and negative resin height separated.
Goal of the invention of the present utility model is exactly the situation according to above-mentioned existence, and a kind of variable flow formula Cationic layer mixing bed that can adopt the Hydrogen mode to move can to adopt ammonification sun bed operating of development, thereby reduce regenerative operation number of times and working cost widely.
The utility model by equipment barrel 1 and the inner water feed apparatus 2 that is provided with from top to bottom thereof, advance the variable flow formula Cationic layer mixing bed that resin device 3, positive resin layer 4, air inlet and feeding/discharging device 5, hybrid resin layer 7, bottom discharging device 8 and resin vent pipe 9 are constituted, the separation surface of described top sun resin layer 4 and bottom hybrid resin layer 7 or separation surface are gone up the place slightly; Discharging device 6 in the middle of being provided with.In addition, compare higher and less being advisable of hybrid resin layer height of bottom of the positive resin layer height on its top with general Cationic layer mixing bed.Discharging device 6 is a female pipe tubular type water dispenser in the middle of described; Also can be non-female other various structure formations of managing a tubular type that can make current enter bottom hybrid resin layer 7, can make water collect and discharge again by it through it.
The variable flow type Cationic layer mixing bed of making according to the utility model can move by general Hydrogen Cationic layer mixing bed mode fully, simultaneously, it structurally possesses again the condition that realizes Ammonifying cation exchange bed operating process with condensed water treatment (see application number for details be 99103737.5 application for a patent for invention specification sheets).Therefore, it can need not make regenerator with highly pure bases, not need to adopt peracid, the alkali regenerant consumption and needn't be to the isolating condition of positive and negative resin height under, when processed condensed water water quality is better, adopt ammonification sun bed operating method, thereby reduce regenerative operation number of times and working cost widely.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
In Fig. 1,1 is that equipment barrel, 2 is that water feed apparatus, 3 is that positive resin layer, 5 is that air inlet and feeding/discharging device, 6 are that middle discharging device, 7 is that hybrid resin layer, 8 is that bottom discharging device, 9 is that resin vent pipe, 10 is that middle outlet valve, 11 is the bottom outlet valve for advancing resin device, 4.
The basic mode that the variable flow type Cationic layer mixing bed is implemented ammonification sun bed operating method is: discharge exhausted resins at Cationic layer mixing bed by vent pipe 9, and changed the outfit behind the good positive and negative resin of regeneration by advancing resin device 3, move by general Cationic layer mixing bed mode earlier.That is, after processed condensed water is entered by top water feed apparatus 2,, discharge via the discharging device 8 of bottom downwards successively through behind positive resin layer 4 and the hybrid resin layer 7.Positive resin layer on top lost efficacy gradually and transferred NH to
4Behind the type (this can be found out by the water quality of taking out water sample from middle discharging device), close bottom outlet valve 11, outlet valve 10 in the middle of opening makes processed condensed water only pass through promptly to be discharged by middle discharging device 6 behind the sun resin layer of top, thus the running status that enters ammonification sun bed.Middle discharging device 6 is located at the separation surface or the separation surface of positive resin layer 4 and hybrid resin layer 7 and goes up the place slightly, and what this discharging device adopted is a female pipe tubular type water dispenser.When realizing ammonification sun bed operating by this way, even be mixed with failure type sun (Na type), cloudy (Cl or SO more, that crossed contamination produces during because of regeneration in the original positive resin layer
4Type) resin particle also not after changing the ammonification operation over to, makes the water quality deterioration of water outlet.Because transfer NH at the positive resin layer on top
4After, these failure type resin particles have also reached balance with processed condensed water already, and failure type ion wherein also is displaced already, has been absorbed in the hybrid resin layer of bottom.
The positive resin layer of ammonification still has corrosion product and the thorough ability of removing the hardness that contains because of the condenser seepage in the good removal water.
Can realize the positive and negative resin under the more thorough isolating condition at the in-vitro separation regeneration system rapidly, can also be after the variable flow type Cationic layer mixing bed have changed the outfit regeneration positive and negative resin well, directly isolated operation sun resin layer (promptly, make into water only by behind the sun resin layer of top, promptly discharge) by middle water-freeing arrangement, make it earlier through the Hydrogen operation, carry out the transition to the ammonification running status again.In this case, in the Hydrogen operation phase, ammonification in water, by the transitory stage of Hydrogen, then to reduce ammonia residual gradually, until stopping ammonification to the operation of ammonia type.
Under the state of positive resin layer isolated operation, if the inlet and outlet pressure difference rises to when higher, can top sun resin layer water inlet backwash or air inlet be cleaned by air inlet and feeding/discharging device 5, the muddy water after the scouring can be discharged by this air inlet and feeding/discharging device.
Under the state of positive resin layer isolated operation, note supervision, confirm that effluent quality is qualified.If any making the underproof situation of effluent quality, exceed standard and silicon-dioxide when higher as the condensed water hydrogen conductivity, should change general Cationic layer mixing bed mode into and move.That is, make processed water downwards by discharging behind positive resin layer and the hybrid resin layer.
