Abstract
The utility model discloses a circulating water cooling device which comprises an air cooling tower, a low temperature pump and a water cooling tower; the air cooling tower, the low temperature pump and the water cooling tower are connected through pipelines; the circulating water cooling device is characterized in that the circulating water cooling device further comprises a refrigerating machine, a low temperature water inlet valve, a low temperature water outlet valve and a first by-pass valve, wherein one end of the low temperature inlet valve is connected with the refrigerating machine through a pipeline, and the other end is connected with the first by-pass valve and the low temperature pump outlet through pipelines; the other end of the first by-pass valve is connected with the air cooling tower and the low temperature water outlet valve through pipelines; and the other end of the low temperature water outlet valve is connected with the refrigerating machine. In the circulating water cooling device, the refrigerating machine is adopted to replace a cold energy that is generated by contacting between nitrogen and cooling water, so as to displace the nitrogen that is originally used for cooling to serve as the product nitrogen, thereby avoiding the waste of nitrogen resources.
Description
Technical field
The utility model relates to a kind of refrigerating unit, is specifically related to a kind of circulating water cooling device.
Background technology
At present, oxygenerator atmospheric cooling tower recirculated water cooling mode is to use the unnecessary nitrogen of technology and the nonsaturation of dirty nitrogen, contacts with water, reduces temperature of cooling water.Under the little situation of nitrogen demand, this kind flow process advantage is to utilize discarded nitrogen, saves the power consumption and the maintenance cost of refrigerator.Because the part nitrogen of oxygenerator nitrogen water precooling flow process is used to cooling circulating water, under the bigger situation of nitrogen demand, on producing, but need oxygenerator of increase because nitrogen supply (NS) is not enough, this just exists waste nitrogen problem of resource.Therefore, need a kind of circulating water cooling device that under the big situation of nitrogen demand, uses.
The utility model content
By Given this, the utility model provides a kind of circulating water cooling device, substitutes part nitrogen contacts generation with water coolant cold with refrigerator, will be used for the refrigerative nitrogen replacement originally and come out, and as product nitrogen gas, has avoided the waste problem of nitrogen resource.
To achieve these goals, the utility model is by the following technical solutions:
A kind of circulating water cooling device, comprise atmospheric cooling tower, cryopump and water-cooling tower, between described atmospheric cooling tower, cryopump and the water-cooling tower through pipe connection, wherein, described circulating water cooling device also comprises refrigerator, water at low temperature imported valve, water at low temperature outlet valve and first by-pass valve, described water at low temperature imported valve one end is through the pipe connection refrigerator, the other end is through pipe connection first by-pass valve and cryopump outlet, the first by-pass valve the other end is through pipe connection atmospheric cooling tower and water at low temperature outlet valve, and the water at low temperature outlet valve the other end connects refrigerator.
Further, described circulating water cooling device also comprises second by-pass valve, and second by-pass valve, one end is through the pipe connection water-cooling tower, and the other end connects the water at low temperature outlet valve and first by-pass valve respectively.
The beneficial effects of the utility model are:
Existing nitrogen water precooling flow process does not have refrigerator, needing to consume in a large number can be as the normal pressure nitrogen of product nitrogen gas, and this device can come out the nitrogen replacement of the purpose that is used to originally to freeze after increasing refrigerator between cryopump and the atmospheric cooling tower, be used as product nitrogen gas, the total reserves that produces with newly-increased refrigerator remedies because of nitrogen and does the cold deficiency of product with the water at low temperature that causes in addition; This device can excavating equipment production potential, increase the output of product nitrogen gas; In oxygenerator user oxygen, nitrogen demand imbalance, under the increasing situation of nitrogen demand, can avoid occurring the oxygenerator operation and only be the supply of nitrogen, and the situation of oxygen emptying.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification sheets or the accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment the utility model is described further:
As shown in Figure 1, this device comprises atmospheric cooling tower 1, cryopump 7, water-cooling tower 8, refrigerator 4, water at low temperature imported valve 5, water at low temperature outlet valve 3, first by-pass valve 2 and second by-pass valve 6; Water-cooling tower and cryopump 7 are through pipe connection, and cryopump 7 connects atmospheric cooling tower 1 through first by-pass valve 2; Water at low temperature imported valve 5 one ends are through pipe connection refrigerator 4, the other end is through pipe connection first by-pass valve 2 and cryopump outlet, first by-pass valve, 2 the other ends are through pipe connection atmospheric cooling tower 1, water at low temperature outlet valve 3 and second by-pass valve 6, water at low temperature outlet valve 3 one ends are through pipe connection refrigerator 4, and the other end is through pipe connection atmospheric cooling tower 1, first by-pass valve 2 and second by-pass valve 6; Second by-pass valve, 6 one ends are through pipe connection water-cooling tower 8, and the other end connects first by-pass valve 2 and water at low temperature outlet valve 3 respectively.
The workflow of this device is:
Water at low temperature imported valve 5 and water at low temperature outlet valve 3 are opened, water at low temperature by water-cooling tower 8 is a high-pressure pump through cryopump 7() afterwards, enter refrigerator 4 by water at low temperature imported valve 5 and reduce temperature, temperature reduces the back and enters into atmospheric cooling tower 1 by water at low temperature outlet valve 3.
When passing through the water shortage of refrigerator 4, by opening second by-pass valve 6, amount of makeup water, the water at low temperature that enters second by-pass valve 6 can the pipeline bypass enter refrigerator 4 behind water at low temperature outlet valve 3 valves, when if temperature reaches specified requirement, can not pass through refrigerator 4, water at low temperature directly enters atmospheric cooling tower 1 through first by-pass valve 2.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
