Realize the technical scheme of the utility model purpose: a kind of fixed bed tower, it comprises that case top is provided with upper cover by upper cover, housing, low head; Housing bottom is provided with low head, and upper cover, housing, low head constitute tower body, and tower body inside is airtight cavity; The upper cover top center is provided with the resin feeding mouth with airtight cavity internal communication, and a side of resin feeding mouth is provided with the solution feed mouth with its internal communication, and the low head bottom is provided with the straight tube of airtight cavity internal communication; Straight tube middle part one side is provided with the drain pipe with its internal communication; The straight tube bottom is provided with ball valve, and wherein, described drain pipe top is provided with bag filter.
Described bag filter top is provided with the solution discharging opening.
Described ball valve bottom is connected with the resin discharge gate, and resin discharge gate bottom is provided with the resin drain valve.
Described upper cover top one side is provided with the liquid level gauge exploration hole with airtight cavity A internal communication.
Described upper cover top one side is provided with exhaust-valve, and exhaust-valve is through pipeline and airtight cavity internal communication.
The useful technique effect of the utility model: the fixed bed tower of the utility model is canceled the quartz sand filtration layer of tower body inner bottom part; And bag filter is installed on the drain pipe top; The solution discharging opening at bag filter top is consistent with the solution feed open height of cat head: the English sand filter course of canceling the tower body inner bottom part; Increase resin volume in the fixed bed tower, increased effective treating capacity of resin; Go out mode under ion exchanged soln is enterprising, and, make solution cloth liquid in the fixed bed tower even through drain pipe, bag filter fluid; Use bag filter to avoid solution to take away ion exchange resin.Compare with fixed bed tower of the prior art, the ion exchange resin in the fixed bed of the utility model can wholely move, and in tower, does not stay mobile dead angle.Fixed bed of the utility model and moving bed hybrid technique flow operations are simple, and initial investment is few.
Description of drawings
Fig. 1 is the structural representation of a kind of fixed bed tower of providing of the utility model.
Among the figure: 1. resin feeding mouth, 2. solution feed mouth, 3. exhaust-valve, 4. resin drain valve; 5. liquid level gauge exploration hole, 6. solution discharging opening, 7. bag filter, 8. drain pipe; 9. ball valve, 10. upper cover, 11. housings, 12. low heads; 13. supporting base, 14. straight tubes, 15. resin discharge gates, the airtight cavity of A..
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
As shown in Figure 1, housing 11 welded top upper covers 10, housing 11 bottoms welding low head 12, upper cover 10, housing 11, low head 12 constitute the tower body of tower, and tower body inside is airtight cavity A.The resin feeding mouth 1 of welding of upper cover 10 top center and airtight cavity A internal communication; One side of resin feeding mouth 1 is provided with the solution feed mouth 2 with its internal communication; Resin feeding mouth 1 is tubulose with solution feed mouth 2; Resin feeding mouth 1 is vertically arranged, solution feed mouth 2 horizontal arrangement, and promptly both axis are orthogonal.Upper cover 10 tops one face down bonding connects exhaust-valve 3, and the bottom of exhaust-valve 3 is through pipeline and airtight cavity A internal communication; The liquid level gauge exploration hole 5 of upper cover 10 top opposite side welding and airtight cavity A internal communication.
As shown in Figure 1, low head 12 is welded on the supporting base 13, and supporting base 13 adopts in the prior art and is used to support jar supporting base of shape structure.The straight tube 14 of welding of low head 12 bottom centre and airtight cavity A internal communication; Middle part one face down bonding of straight tube 14 connects the drain pipe 8 with its internal communication; Straight tube 14 bottoms are connected with the top of ball valve 9 through screw thread; The bottom of ball valve 9 is connected with resin discharge gate 15 tops through screw thread, and resin discharge gate 15 is a L type pipe, and the bottom of resin discharge gate 15 is provided with resin drain valve 4.Drain pipe 8 is a L type pipe, and the top of the long tube of drain pipe 8 is connected with bag filter 7 bottoms are arranged through adpting flange, and both adpting flanges connect through bolt.Bag filter 7 tops are provided with the solution discharging opening 6 of horizontal arrangement.Bag filter 7 is used to isolate ion exchange resin, avoids solution to take away ion exchange resin.Solution discharging opening 6 guarantees that than the low approximately 10cm of solution feed mouth 2 mill solution forms discrepancy in elevation gravity flow.
The fixed bed tower of the utility model removes the quartz sand filtration layer of original fixed bed Tata body inner bottom part, and a bag type filtering apparatus 7 is installed at drain pipe 8 tops.Bag filter 7 is installed in the outlet pipe top of drain pipe 8, reduces bag filter 7 and bears pressure.The several medium situation according to the filler in the fixed bed of the filtration order of bag filter 7 are selected; It is 40 purpose filter bags that the bag filter of for example tackling ion exchange resin can be selected the order number, tackles other filler are selected filter bag according to its minimum medium volume order number.
The operation principle of a kind of fixed bed tower that the utility model provided: close resin drain valve 4 and ball valve 9; Ion exchange resin joins in the tower body from the resin feeding mouth 1 of cat head; Ion exchanged soln from solution feed mouth 2 in tower body; Through the amount that liquid level gauge exploration hole 5 control ion exchange resin and ion exchanged soln add, the ion exchanged soln after ion-exchange process is accomplished is from straight tube 14 entering drain pipes 8, again through solution discharging opening 6 fluids at bag filter 7 tops.After ion-exchange is accomplished, open resin drain valve 4 and ball valve 9, ion exchange resin is discharged through straight tube 14, L type discharge gate 15 successively.Ion exchanged soln is to go out under enterprising, through the ion exchange resin bed volume, through bag filter 7 fluids, has effects such as all even assurance solution of cloth liquid is limpid from drain pipe 8.
Combine accompanying drawing and embodiment that the utility model has been done detailed description above; But the utility model is not limited to the foregoing description; In the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from aim of the present invention, make various variations.The content of not doing in the utility model to describe in detail all can adopt prior art.
