Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
100MeV cyclotron complex structure, needs to set up a set of perfect circulating water cooling system and meets its particular/special requirement, for accelerator facility is long-term, stable operation lays the first stone.This circulating water cooling system, refrigeration work consumption large (about 500kW), system nominal discharge 65T/h.In order to prevent cooling water pipe encrustation, keep the insulation property of high voltage installation (>=40kV), require that water quality is better than 0.5 μ s/cm.Therefore, circulating water cooling system must be equipped with a set of online deionization production and water correction device.During normal work, this circulation continuous operation water consumption every day more than about 8 tons.The water saving measures succeeded in developing, using water wisely every day about 8 tons, while the high-quality condition maintaining recirculated water, reaches water saving object.Both decrease operating cost, again save valuable water resources.
In the utility model, a circulating water loop (direct cooling device, take heat out of) and the secondary cycle water loop (distribute heat, make water cooling) of water chiller all have employed enclosed construction, eliminates any loss and the waste of major cycle water; The hot water once circulated directly enters secondary cycle and cools, and eliminates the conventional heat exchanger be added between first and second circulation, improves refrigerating efficiency, achieves simultaneously and saves engineering funds, economize on electricity and water saving 3 functions.
Circulation structure after improvement as shown in Figure 2, a longitudinal baffle is provided with in main water box inside, water tank is divided into left and right two parts, but, divider height is slightly lower than tank height, and namely the left and right two parts of water tank communicate on top, and this particular design can make two water circulations share a water tank, also first and second recirculated water can be made to be separated from each other, to improve cooling effect.Left and right two parts are respectively cold water area and hydrothermal area, and hot water, from the water intaking of main water box cold water area, after flowing through accelerator water equipment, is injected main water box hydrothermal area by a described circulating water loop; Cold water, from main water box hydrothermal area water intaking, after flowing through cooling system equipment, is injected main water box cold water area by described secondary cycle water loop; A circulating water loop and secondary cycle water loop are all in closed independent operating.If this innovative design also solve satisfactorily two circulation discharge asynchronous, may cause water tank side that excessive problem occurs.Meanwhile, because first and second circulation waterway is all closed, any water loss is eliminated.
Cyclotron circulation generally has a normal moisturizing flow process, the moisturizing flow process (1) namely in Fig. 1.The process of moisturizing flow process (1) is as follows: running water → raw water box → preliminary treatment → double-stage reverse osmosis → reverse osmosis water tank (RO water tank) → ion-exchange treatment (EDI) → main water box.Because accelerator facility requires that circulating cooling water quality is better than 0.5 μ s/cm, online ' deionized water is produced and water correction device ' provides qualified cooling water for water chiller, and the cooling water be deteriorated is carried out water correction.Usually, the efficiency of deionized water production procedure is about 70%, and water correction flow path efficiency is about 85-90%.What water saving measures of the present utility model ensure that discharge water in water correction flow process is all recycled, reuse.See the right part of control flow in Fig. 1: the dense water of water correction flow process is injected raw water box, after raw water box is full, start moisturizing flow process (2) immediately, by the dense water in raw water box successively after preliminary treatment, double-stage reverse osmosis process, ion-exchange treatment, inject the cold water area of main water box, secondary moisturizing is carried out to main water box.Go round and begin again, the dense water of water correction flow process is all recycled.
Deionized water produce and water correction device structure as shown in Figure 3, due to cyclotron water equipment complexity, water quality requirement is high.In order to remain the high-quality (being better than 0.5 μ s/cm) of recirculated water, the water correction process flow operation time is longer, about 20 hours every days.With water correction discharge 2M
3/ h, efficiency 85% calculates, and will there be 7.2M every day
3waste water be discharged.In order to these wastewater reuses can be made, add moisturizing flow process (2), that is: the discharge water (dense water) of EDI is first injected raw water box, once raw water box reaches high water level, start moisturizing flow process (2) immediately, by the water of raw water box, via preliminary treatment, reverse osmosis, become clean water and return RO water tank.Visible, a thus much corrective measure can save 7.2 tons of water every day.
Pre-processing device in deionized water production procedure needs regular backwash, cleaning dirt, generally all discharging as waste water with water of backwash process.Conventional backwash is with system energization Time Calculation.According to practical situation, number of backwashes is too much, unnecessarily waste water resource.The utility model makes system energization timing into work timing, and such number of backwashes will determine according to System production time, and not only science, but also using water wisely, killed two birds with one stone.See the left part of Fig. 1 control flow: when moisturizing (1)+moisturizing (2) time used, (T1+T2) equaled setting-up time Ts, just carry out backwash, have nothing to do with the system energization time.Operative practice is indicated, the cumulative time of Ts every day is about 5 hours, is only 5/24 ≈ 1/5 of conduction time.Dimension, the water consumption of backwash can be reduced to 1/5 of former water consumption by the Optimized Measures of backwash flow process.
The utility model is by the innovative design of circulation structure, the moisturizing flow process (2) increased in water correction process, the backwash flow process etc. of scientific optimization pre-processing device, accomplish using water wisely, dense water is repeated, recycled, wastewater discharge has been reduced to minimum; Meanwhile, the backwash cycle calculates according to the operating time completely, science, rationally.Since system puts into operation, stable performance, obviously (using water wisely every day about 8 tons), water consumption greatly reduces water-saving result.And, can accomplish that a key operation, whole-course automation control, without the need to human attendance.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if belong within the scope of the utility model claim and equivalent technology thereof to these amendments of the present utility model and modification, then the utility model is also intended to comprise these change and modification.
