Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The embodiment provides a cooling water supply system based on an internal and external double circulation loop, which is used for cooling an electrolytic cell and comprises an electrolytic cell 103, a pure water tank 101 communicated with a circulation pipeline of the electrolytic cell and a heat exchanger 105 used for inputting cooling water to the electrolytic cell, as shown in figures 1 and 2.
As shown in fig. 1, the heat exchanger is provided with two water input pipelines, one of which is connected with the cooling water input port, and the other of which is connected with the pure water tank, so that the water in the pure water tank can be cooled by inputting cooling water; the heat exchanger is used for cooling input water in a heat exchange mode, low-temperature constant-temperature supply of cooling water can be guaranteed, the heat exchanger can adjust the temperature of output cooling water by adjusting the working efficiency of the heat exchanger, and the specific structure and the adjusting mode of the heat exchanger can be realized by the prior art.
The pure water tank 101 has one end to which cooling water is supplied to the electrolytic bath 103 through the heat exchanger 105, and the other end to which cooling water and oxygen gas electrolyzed by the electrolytic bath are supplied; and, the said electrolytic cell inputs oxygen to the said pure water tank after electrolyzing water, and input hydrogen to the external steam-water separation device 102, namely after the water in the pure water tank passes the heat exchanger, output the cooling water of the set temperature to the electrolytic cell, after the electrolytic cell electrolyzes water, its two poles produce hydrogen and oxygen separately, hydrogen and oxygen all carry a large amount of steam, therefore, can carry on the steam-water separation by inputting hydrogen into the steam-water separation device, after purifying, collect hydrogen, and, through conveying the oxygen with steam back to the pure water tank, through installing the oxygen blower in connection with pure water tank, reclaim oxygen.
And a flow control valve is arranged between the external cooling water input port and the heat exchanger, and the flow control valve can control the inflow and outflow of the cooling water of the heat exchanger by increasing the pressure, so that the flow rate of the cooling water in the heat exchanger can be controlled, and the working efficiency of the heat exchanger can be controlled.
A jet pump 104 is provided between the deionized water tank and the heat exchanger in the direction in which the water in the deionized water tank flows into the heat exchanger; and the water flow of the heat exchanger circulates back to the direction of the pure water tank, a filtering cylinder 107 is arranged between the heat exchanger and the pure water tank, wherein the number of the filtering cylinders 107 is two, the filtering cylinders are a filtering sand cylinder and a ceramic filtering cylinder, the filtering sand cylinder and the ceramic filtering cylinder can respectively filter different impurities, and the filtering effect is better.
Wherein, the electrolysis bath can have impurity to separate out when working, can influence the quality of water in the pure water case like this, so just need filter the water in the pure water case thereby guarantee that the water storage in the pure water case keeps sufficient purity all the time. Thus, the water in the pure water tank is pushed out in a high-pressure state by the jet pump, which contributes to smooth circulation of the water in the electrolytic bath. And the water is divided into two parts after passing through the heat exchanger, one part is supplied to the electrolytic bath, and the other part passes through the filter cylinder; after water passes through the filter cylinder, the water pressure is influenced, which is also the reason that only one path of water which passes through the filter cylinder and then passes through the electrolytic bath is not selected after the water passes through the heat exchanger; therefore, two paths of water are selected, so that the normal operation of the electrolytic cell is ensured, and the water in the water tank is filtered.
Pressure sensors are respectively arranged between the heat exchanger and the pure water tank and between the heat exchanger and the electrolytic bath; the pressure sensor is used for collecting the water flow pressure of the heat exchanger flowing to the pure water tank and the electrolytic cell respectively, so that the water flow can be controlled within a normal pressure range, the safety performance of the equipment is ensured, and the service life of the equipment is prolonged.
The temperature sensor is also arranged in the electrolytic cell and used for detecting the temperature in the electrolytic cell, and the abnormal operation of the electrolytic cell is prevented through the detection of the temperature of the electrolytic cell; the electrolytic bath works to provide a constant current source, and the abnormal working of the electrolytic bath indicates that the voltage of the electrolytic bath is too high, the heat generated in the working process is too large, the working efficiency of the electrolytic bath is influenced by too high temperature besides consuming redundant power consumption, and the working life of the electrolytic bath is shortened; thus, by detecting the temperature, measures can be taken in time to lower the temperature in the electrolytic cell, for example, to increase the circulating flow rate of the cooling water.
The water purifier is characterized by also comprising a drainage pipeline, wherein the drainage pipeline is respectively connected with the pure water tank, the heat exchanger and the steam-water separation device, a drainage outlet of the drainage pipeline is provided with a drainage valve, a manual valve is arranged between the drainage pipeline and the pure water tank, and water in the drainage pipeline can also be input into the heat exchanger through the drainage pipeline, so that the water in the drainage pipeline can be repeatedly used; water in the pure water tank can also flow to the heat exchanger through the drainage pipeline and can also be discharged outside through the drainage pipeline, and the pure water tank can be specifically set according to application scenes and actual use requirements.
In addition, each temperature sensor, liquid level sensor, pressure sensor, drain valve, flow control valve and the like of the invention are connected with an external control system, and can process each temperature data, each liquid level data and each pressure data through the control system, and can control the automatic opening and closing of each valve and each switch through control, and the specific composition, the connection structure, the composition software and the like of the control system can be realized through the prior art, and the description is omitted here.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
