Description

Double-loop closed-circulation pure water cooler

The utility model relates to the water cooling equipment circulatory system, the pure water cooler of particularly a kind of double loop, closed circulation.

At present, the water cooling equipment circulatory system of China's extensive use, most typical structure as shown in Figure 2, whole system is formed by heat exchanger (2), refrigerator (3), cooling tower (4), pond (5) and water circulating pump equipment such as (6-8) and combination of facilities.Fig. 2 shows, after the heat absorption of main cooling medium in the major loop with giant mechanical and electrical equipment load generation, entering heat exchanger (2) carries out cold, the heat exchange of hot fluid next door, the main cooling medium that unloads after the heat flows back to water storage tank, water circulating pump (8) is drawn main cooling medium from water storage tank again and is given load, the circulation cooling that formation goes round and begins again, and after pair cooling water heat absorption of heat exchanger (2), by water circulating pump (7) it is delivered to refrigerator (3) and cool off, refrigerator (3) self absorbs heat and the heat of generation, delivers to cooling tower (4) by pump (6), after the air water heat exchange, waste hot gas enters atmosphere by the tower nozzle, after a circulation pair cooling water unloads heat, gets back to the pond.There is following several respects weak point in it: 1, structure is disperseed, and floor space is big; 2, water consumption is surprising, and cold effect is not high; 3, equipment scaling is serious, and particularly the open circulation loop is particularly serious.4, equipment operation integrated cost height.

The purpose of this utility model is that design a kind ofly need not add cooling water, floor space little double-loop closed-circulation pure water cooler.

In order to achieve the above object, the utility model adopts following technical solution: a kind of double-loop closed-circulation pure water cooler, comprise the I closed loop, this loop mainly is made of water circulating pump group, apparatus for eliminating sludge, expansion tank, plate type heat exchanger and mixed bed exchange column, its two ends, loop are connected in the load, be provided with the II closed loop in plate type heat exchanger time side, plate type heat exchanger time side two ends are connected with two ends, II closed loop, the plate-type evaporator in other two ends, II closed loop and the Cool-water Machine for Industry) master is connected.

Owing to utilize the setting temperature difference of Cool-water Machine for Industry generation and the metered flow of output,, take away the heat of load (giant mechanical and electrical equipment) by the mode of closed circulation cooling.It has sliced off cooling tower and pond facility, has removed cooling water, realizes that its floor space is little, water cooling equipment need not the purpose with cooling water.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the structure principle chart of present embodiment.

Fig. 2 is typical existing water cooling equipment circulatory system schematic diagram.

As shown in Figure 1, present embodiment comprises I closed loop, II closed loop, Cool-water Machine for Industry.Wherein, the two ends of I closed loop are connected in the load, the two ends of II closed loop are connected with the inferior side of plate type heat exchanger (10) two ends in the I closed loop, and the other two ends in the II closed loop are connected with plate-type evaporator master in the Cool-water Machine for Industry.

The I closed loop mainly is made of circulating pump group (P1-1, P1-2), apparatus for eliminating sludge (15), expansion tank (11), plate type heat exchanger (10) and mixed bed exchange column (9), and the II closed loop mainly also is made of circulating pump group (P2-1, P2-1), water storage tank (14), mixed bed exchange column (12).Mixed bed exchange column (9), (12) respectively and be connected on I, the II loop, its adopts strong acid, strong base ion exchange resin mixed bed system, it can keep higher pure water water quality purity effectively, and prolongs the regeneration period of exchanger resin.Interconnect by electrically operated valve DK3 between two tie points of inferior side of the plate type heat exchanger in the I closed loop (10) and II closed loop, reach the effect of the inferior effluent amount of automatic adjusting plate type heat exchanger (10), thereby make the load temperature difference steady.

Ginseng is stated systematic schematic diagram (Fig. 1), and the course of work of this device is as follows:

Cooling medium in the I closed loop (pure water), behind heating load draw heat, through by-pass valve control K1 and K2, the cooling medium (pure water) of band heat enters in the plate type heat exchanger (10) and unloads heat.Unload the pure water after the heat,, flow into expansion tank (11) through by-pass valve control K3.The pure water of heat has been unloaded in circulating pump group (P1-1, P1-2) absorption from expansion tank (11), squeezes into the heating load and continues heat absorption.The pure water of I closed loop has been finished heat absorption and has been unloaded hot task.

Low temperature pure water in the II closed loop under the promotion of water circulating pump (P2-1, P2-2), through electrically operated valve DK2, enters in the plate type heat exchanger (10), and the heat that the I closed loop passes over is accepted in the next door.The pure water of band heat enters in the heat exchange evaporimeter and cools off by electrically operated valve DK1 and by-pass valve control K6.Cooled pure water reverts to the low temperature pure water again, and the by-pass valve control K7 that flows through enters water storage tank (mixing).The pure water that the circulating pump group extracts in the water storage tank is squeezed in the plate type heat exchanger again, continues to accept the heat that first closed loop passes over.The task of being heated and cooling off has also been finished in the II closed loop therefore.

Above-mentioned two loops all adopt pure water (deionized water) as medium, by the closed circulation that goes round and begins again, finish heat absorption and cooling task.

Cool-water Machine for Industry in this device by processes such as compression, condensation, expansion, evaporations, has absorbed the heat in the II closed loop.Pass through the effect of aerial cooler again, make it become waste hot gas, discharge and enter atmosphere.Its operation principle is: the environmental protection cold-producing medium is draw heat and constantly evaporation from the heat exchange evaporimeter, becomes steam, enters compressor, compression therein, thus the temperature and pressure of cold-producing medium is sharply raise, become superheated vapor.After superheated vapor entered condenser, heat was taken away by aerial cooler, became waste hot gas, discharged to enter atmosphere.Cooled cold-producing medium becomes saturated vapor gradually, and then becomes liquid gradually.By decompression original paper (expansion valve) throttling action, become the liquid vapour mixture of low-temp low-pressure, enter heat exchange (evaporation) device and begin new one again and take turns the kind of refrigeration cycle process.

The physics apparatus for eliminating sludge of series connection in the I loop its objective is the generation that prevents non-corrosion resistant metal surface dirt layer in the load pipe-line system effectively.

In sum, the utility model compared with prior art has the following advantages: 1, keeps the water-cooled characteristic, need not add cooling water, save great lot of water resources; 2, cold effect is high. 3, non-scaling, not dewfall, no exhaust emission. 4, save cooling tower and pond, complete machine one, compact conformation. 5, operating cost is low, only has the electricity charge, does not have water rate.
