Abstract
Description
Technical Field
[0001] The invention relates to a cooling water temperature reduction device. Background Art
[0002] In the process of industrial production, a large amount of cooling water is often required to cool the equipment to ensure its normal operation. The cooling water supply system usually adopts a circulating supply method, using open cooling facilities such as cooling towers to cool the high-temperature cooling water at the equipment outlet and then recycle it. Under the high temperature and high humidity atmospheric conditions in summer, the cooling effect of open cooling facilities such as cooling towers is affected, resulting in the water supply system being unable to meet the equipment's requirements for the cooling water inlet temperature. In this case, in order to ensure normal production, there are two main solutions: one is to increase the amount of low-temperature new water added, which will cause a waste of water resources; the other is to add new refrigeration equipment to cool the cooling water, which requires additional investment and maintenance costs. Summary of the invention
[0003] The technical problem to be solved by the present invention is to overcome the problem that when the cooling effect of existing open cooling facilities such as cooling towers is affected under high temperature and high humidity atmospheric conditions in summer, increasing the amount of low-temperature new water added causes waste of water resources and additional costs for new refrigeration equipment, and provide a new cooling water cooling device.
[0004] In order to solve the above problems, the present invention is implemented through the following scheme: the cooling water temperature reduction device is composed of a low-temperature water pipeline, a vacuum container, a vacuum pipeline, a vacuum pump, a high-temperature water pipeline, a water pump, and a cooling water container. When the cooling water needs to be cooled, the vacuum container is evacuated by a vacuum pump, and the high-temperature cooling water in the cooling water container is pumped into the vacuum container through the high-temperature water pipeline by a water pump. A part of the high-temperature cooling water absorbs heat and evaporates in the vacuum container, and is sucked into the atmosphere by the vacuum pump through the vacuum pipeline, and the remaining part releases heat and the temperature is reduced, and it flows back to the cooling water container through the low-temperature water pipeline. After a certain period of operation, the water temperature in the entire cooling water container will be reduced.
[0005] Due to the adoption of the above scheme, compared with open cooling facilities such as cooling towers, the present invention can effectively reduce the cooling water temperature under high temperature and high humidity atmospheric conditions in summer, avoiding the waste of water resources caused by increasing the amount of low-temperature new water replenishment; compared with existing refrigeration equipment, it can reduce the additional cost investment and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0006] Figure 1 The utility model is a schematic diagram of a cooling water temperature reduction device of the present invention. DETAILED DESCRIPTION
[0007] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0008] By the attached Figure 1 It is given that the cooling water cooling device of the present invention is composed of a low-temperature water pipeline 1, a vacuum container 2, a vacuum pipeline 3, a vacuum pump 4, a high-temperature water pipeline 5, a water pump 6, and a cooling water container 7. The interface between the low-temperature water pipeline 1 and the vacuum container 2 is located at the lower part of the vacuum container 2, the interface position is higher than the liquid level in the cooling water container 7, and the height difference does not exceed the water column height corresponding to the local atmospheric pressure. The interface between the vacuum pipeline 3 and the vacuum container 2 is located at the upper part of the vacuum container 2, the interface position is higher than the liquid level in the cooling water container 7, and the height difference is greater than 10 meters. The interface between the high-temperature water pipeline 5 and the vacuum container 2 is located in the middle and upper part of the vacuum container 2, the interface position is higher than the interface position between the low-temperature water pipeline 1 and the vacuum container 2, and lower than the interface position between the vacuum pipeline 3 and the vacuum container 2. The vacuum pump 4 needs to be a vacuum pump suitable for pumping water vapor, and its suction limit pressure should be lower than the saturated steam pressure corresponding to the temperature to which the cooling water needs to be reduced. The interface between the low-temperature water pipeline 1 and the cooling water container 7 is located at the bottom of the cooling water container 7, and the interface between the high-temperature water pipeline 5 and the cooling water container 7 is located below the water surface of the cooling water container 7 and close to the water surface, and the two interface positions are as far away as possible. When the ambient temperature is higher than the temperature to which the cooling water needs to be lowered, insulation measures need to be taken for the low-temperature water pipeline 1, the vacuum container 2, the high-temperature water pipeline 5, and the cooling water container 7.
[0009] When the cooling water needs to be cooled, the vacuum container 2 is evacuated by the vacuum pump 4, and the high-temperature cooling water in the cooling water container 7 is pumped into the vacuum container 2 through the high-temperature water pipeline 5 by the water pump 6. Part of the high-temperature cooling water absorbs heat and evaporates in the vacuum container, and is sucked into the atmosphere by the vacuum pump 4 through the vacuum pipeline 3, and the remaining part releases heat and lowers its temperature, and flows back to the cooling water container 7 through the low-temperature water pipeline 1. The pressure in the vacuum container 7 is made to reach or be lower than the saturated steam pressure corresponding to the temperature to which the cooling water needs to be reduced. For example, if the water temperature is to be reduced to below 30°C, the pressure in the vacuum container 7 needs to be below 4.2kPa; if the water temperature is to be reduced to below 20°C, the pressure in the vacuum container 7 needs to be below 2.3kPa; if the water temperature is to be reduced to below 15°C, the pressure in the vacuum container 7 needs to be below 1.72kPa. After a certain period of operation, the water temperature in the entire cooling water container 7 will be reduced to the required temperature.
[0010] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
