Abstract
The utility model discloses a mixed bed ion exchanger and belongs to the technical field of ion exchanging. The mixed bed ion exchanger comprises a casing. A liquid inlet pipe and a liquid outlet pipe are arranged on the casing, an upper partition plate and a lower partition plate are arranged in the casing, water caps are respectively arranged on the upper partition plate and the lower partition plate, and resin is arranged between the upper partition plate and the lower partition plate. Each water cap is composed of a cap cover, a cap base, a flow guiding pipe and two fixing nuts. Rib-shaped seams are arranged on the cap covers. The mixed bed ion exchanger is characterized in that the water caps are made of stainless steel, sealing gaskets are arranged between the cap covers and the cap bases, and two fixing nuts are close to a thread portion fixed on each flow guiding pipe. The water caps for the exchanger are reasonable in structure, firm in connection, high in pressure bearing strength and capable of avoiding tripping and cracking and improve working reliability of a mixed bed ion exchanging system.
Description
Technical field
The utility model relates to ion-exchange separation field, particularly mixed-bed exchanger.
Background technology
So-called mixed bed, be exactly a certain proportion of cationic, anionic exchange resin mixed packing in same switch, the ion in the convection cell exchanges, removes.Because the proportion of positive resin is larger than negative resin, so negative resin is descending at the Shangyang resin in mixed bed.The ratio of general positive and negative resin filling is 1:2, also can take the circumstances into consideration to consider to select by different resins.
In mixed bed, because the yin, yang resin is mutual mixing, so its yin, yang ion exchange reaction is almost carried out simultaneously.After mixed bed operational failure, must manage the yin, yang resin isolation, so that regeneration.So, every certain cycle, need to carry out big reverse washing to bed.Because big reverse washing needs certain flow velocity and flow, therefore, the water cap in the mixed bed ion exchange system must satisfy the requirement of big reverse washing.
Mixed bed water cap is the captation of mixed bed, is used for mixed bed and catchments and prevent that resin from spilling.Traditional water cap is comprised of calotte, cap seat, thrust-augmenting nozzle and set screw nut, and calotte and cap seat are fastened on the dividing plate by threaded thrust-augmenting nozzle and set screw nut after fastening.Traditional water cap adopts plastic material, its intensity difference, withstand voltage, heatproof, loss of properties on aging, and especially intensity difference is more outstanding, when big reverse washing, easily threads off, cracking, affects the equipment operating safety.
The utility model content
The shortcoming that exists in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of mixed-bed exchanger, and this interchanger water cap structure is reasonable, be connected firmly, bearing resistance is high, does not thread off and ftractures, and improves the reliability of mixed bed ion exchange system work.
For addressing the above problem, the utility model is by the following technical solutions: this mixed-bed exchanger, comprise housing, liquid inlet tube and liquid outlet tube are arranged on the housing, in housing, be provided with upper spacer and lower clapboard, be equipped with the water cap at upper spacer and lower clapboard, it is resin between upper spacer and the lower clapboard, described water cap is by calotte, the cap seat, thrust-augmenting nozzle and set screw nut form, and calotte is provided with umbrella frame shape bar seam, it is characterized in that, described water cap is that stainless material is made, be provided with gasket between calotte and cap seat, described set screw nut is two, nestles up the threaded portion that is fixed on thrust-augmenting nozzle.
The bar gap of described calotte is from 0.15mm to 0.25mm.
The bar gap of described calotte is inboard large, and the outside is little, and minimum clearance is that 0.15mm is to 0.25mm.
The beneficial effects of the utility model are: the utility model temperature influence is little, corrosion-resistant, anti-aging, long service life, easily change safety and environmental protection.Make because the water cap is stainless material, can improve its rigidity, avoid threading off, ftractureing; Owing between calotte and cap seat, being provided with gasket, when fastening, have certain recoverable deformation between calotte and the cap seat, prevent that calotte from being crushed too greatly because of fastening force; Set screw nut is two and nestles up the threaded portion that is fixed on thrust-augmenting nozzle to have the locking effect, prevents from causing resin to be gone out because set screw nut is loosening.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of water cap;
Among the figure: 1 liquid inlet tube, 2 upper brackets, 3 housings, 4 upper spacers, 5 water caps, 6 resins, 7 lower clapboards, 8 liquid outlet tubes, 9 lower brackets, 51 thrust-augmenting nozzles, 52 calottes, 53 cap seats, 54 gaskets, 55 first set screw nuts, 56 second set screw nuts.
Embodiment
Such as Fig. 1, Fig. 2, this mixed-bed exchanger, comprise housing 3, liquid inlet tube 1 and liquid outlet tube 8 are arranged on the housing 3, are provided with upper spacer 4 and lower clapboard 7 in housing 3, dividing plate mainly can bear the pressure of resin layer and liquid, usually the dividing plate that little bed body and function 16mm is thick is just enough, and slightly large bed body adopts the thick dividing plate of 20mm, further, upper spacer 4 and lower clapboard 7 are fixed on the housing by upper bracket 2 and lower bracket 9 respectively, and its rigidity is strengthened.Being equipped with water cap 5 at upper spacer 4 and lower clapboard 7, is resin 6 between upper spacer and the lower clapboard.
Be provided with gasket 54 between calotte and cap seat, described set screw nut is two, and the first set screw nut 55 and the second set screw nut 56 nestle up the threaded portion that is fixed on thrust-augmenting nozzle.
When backwash, liquid inlet tube 1 is the backwash liquor outlet, and liquid outlet tube 8 is the backwash liquor import.
The above, principles more of the present utility model just explain through diagrams, this specification sheets be not be the utility model to be confined to shown in described concrete structure and the scope of application, therefore every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
