The device of quick cooling circulating water
Technical field
The utility model relates to the water refrigeration technology field, especially fast the device of cooling circulating water.
Background technology
, in the process of producing bacterium, often there is sterilizing in the enterprise of food processing factory, pharmaceutical factory and related industries production bacterium, and cooling and incubation, after sterilizing, need drop to the 25-30 degree by the 70-80 degree by the temperature of charge in equipment.Method therefor, as shown in Figure 1, be generally, with water pump 3, the water of 2 li of circulating water pools is squeezed into to cooling tower 4, two, after cooling tower 4 is cooling, in access arrangement 1, equipment 1 carried out to the circulation temperature lowering processing.The method one is that water consumption is large, the 2nd, cool time is long, the 3rd, cooling tower 4 is required high, must be resistant to elevated temperatures cooling tower 4.
The utility model content
The utility model, for deficiency, proposes a kind of device of quick cooling circulating water, and water consumption is little, and cool time is short, has reduced the instructions for use of cooling tower technological design.
In order to realize above-mentioned utility model the first purpose, the utility model provides following technical scheme: a kind of device of quick cooling circulating water, comprise the circulating water pool, water pump and the cooling tower that are communicated with successively, the delivery port of cooling tower and the water inlet of circulating water pool are communicated with the equipment of need cooling respectively; Also include hotness valve and high temperature pond, the hotness valve is located at the water inlet of circulating water pool and needs between the equipment of cooling, and high temperature pond and circulating water pool are arranged in parallel.
Further, be equipped with valve between high temperature pond and circulating water pool and cooling tower.
Further, the 3-6 that the capacity of circulating water pool is the high-temperature water tankage doubly.
Compared with prior art, the utlity model has following advantage: on the basis of existing circulatory pool, increase and build a high temperature pond, be installed in addition with a hotness valve on pipeline, under the prerequisite of the pond of equal volume, take out the volume in pond 20% and do the high temperature pond, can shorten cool time more than 20%, can reduce the buying standard of cooling tower, reduce investment outlay and running cost.
The utility model cooling procedure is according to the water temperature difference of need coolings, and selects different cisterns, prevents that high water temperature from sneaking in most of low water temperature recirculated water, thereby reduces water consumption, shortens cool time, reduces the serviceability temperature requirement of cooling tower.
The accompanying drawing explanation
The structural representation that Fig. 1 is prior art;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should any restriction not arranged to protection domain of the present utility model.
The device of a kind of quick cooling circulating water as shown in Figure 2, comprise the circulating water pool 2, water pump 3 and the cooling tower 4 that are communicated with successively, and the water inlet of the delivery port of cooling tower 4 and circulating water pool 2 is communicated with the equipment 1 of need cooling respectively; Also include hotness valve 5 and high temperature pond 21, hotness valve 5 is located at the water inlet of circulating water pool 2 and needs between the equipment 1 of cooling, and high temperature pond 21 and circulating water pool 2 are for being arranged in parallel.
For convenience of operation, all be equipped with valve at the water outlet of high temperature pond 21 and circulating water pool 2, the 3-6 that the capacity of circulating water pool 2 is high temperature pond 21 capacity simultaneously is doubly.
In the situation of the pond of same capacity, the capacity that is circulating water pool 2 in prior art is A, in the utility model, the total capacity of high temperature pond 21 capacity and circulating water pool 2 is also A, when the capacity of circulating water pool 2 is 4 times of high temperature pond 21 capacity, can shorten cool time more than 20%.
The course of work of the quick cooling circulating water device of the utility model is: just begun to cool down circulation time, when the water temperature that equipment 1 is discharged exceeds the operating temperature (more than 60 degree) of cooling tower 4 regulations, hotness valve 5 imports high temperature pond 21 by hot water; When water temperature meets the operating temperature (below 60 degree) of cooling tower 4 regulations, hotness valve 5 imports hot water in circulating water pool 2, the operating temperature water that water pump 3 will meet cooling tower 4 regulations pumps into cooling tower 4, be that valve 61 and valve 62 are selectively opened, the water after cooling tower 4 coolings enters and needs the equipment 1 of cooling to carry out normal cool cycles work.
The water that the high temperature pond is 21 li, lowered the temperature naturally through an evening, and water temperature has approached the cooling water temperature, can close the valve 62 of often opening, and opens valve 61, and the water in 21 li, the high temperature pond of finding time, add to 2 li of circulating water pools, makes the treat work state of high temperature pond 21 in empty pond.
