Description

Technical Field

[0001] The utility model belongs to the technical field of energy conservation and environmental protection, and specifically relates to a water-saving skid-mounted cooling system. Background Art

[0002] The existing cooling system is usually an open cooling tower, which sprays circulating water onto the glass fiber filler in a spray manner, and the water and air come into contact to achieve heat exchange. The fan then drives the air flow in the tower to bring out the hot air flow generated after the heat exchange, thereby achieving cooling.

[0003] The initial investment of an open cooling tower is relatively small, but the operating cost is higher.

[0004] First, in the countercurrent heat transfer process between hot water and air in the open cooling tower, the hot water will wash the air. The solid particles such as dust in the air will enter the cooling water body under the washing effect, forming a large amount of suspended matter. These suspended particles will affect the density of the metal surface film, destroy the integrity of the protective film, promote metal corrosion, and accelerate the accumulation of sediments. 3 / h, taking a cooling system with a water temperature difference of 5°C as an example, it takes about 0.12m3 of cooling water to reduce 1°C by 1kg. 3 Air, according to GB3095-2012 ambient air quality standard, the secondary total suspended particulate matter TSP value is 0.3mg / m 3 , based on 300 working days throughout the year, the amount of suspended matter entering the water body is 1296kg. When the suspended matter forms sludge with a water content of 80% in the cooling water system, it has a huge volume. At the same time, sand, leaves, insects, microorganisms, metabolic products, and soluble gases such as sulfur dioxide, hydrogen sulfide, and ammonia also enter the water body with the air, seriously affecting the normal operation of the open cooling tower.

[0005] Secondly, air has a similar effect to gas lift on cooling water. The contact between air and cooling water will cause carbon dioxide in the water to escape, increase the alkalinity in the water, accelerate the reaction rate of bicarbonate to carbonate, and show that the pH value of circulating water is higher than that of supplementary water, which increases the tendency of calcium carbonate and other scaling precipitation, causing a large amount of dirt to be deposited inside the cooling tower. In addition, since the cooling water of the open cooling tower is in full contact with the air, the amount of dissolved oxygen in the cooling water consumed in the process of metal corrosion will be fully replenished at the gas-liquid junction in the cooling tower. Therefore, the dissolved oxygen in the cooling water will continue to be saturated. Once oxygen chemical metal corrosion occurs in the cooling tower, it will continue. In addition, due to the good light at the cooling tower, a suitable temperature is formed, and the aerobic environment created by the saturated dissolved oxygen in the cooling water, the sediment adheres to the surface of the filler to provide sufficient nutrients. These conditions are very conducive to the reproduction of microorganisms. A large number of microorganisms will be formed in the cooling tower. Under the scouring of the water flow, some microorganisms and their metabolic products will continue to enter the water body with mud.

[0006] Thirdly, the solid powder and gas generated during the production process will be sucked into the cooling tower with the airflow. Some will enter the water body to increase the COD value, some will adhere to the surface of the cooling tower's filler, and some will undergo polymerization, cross-linking and other reactions in the filler gaps to form a viscous paste that blocks the water flow channel and reduces the water density. In severe cases, it will collapse the filler and even migrate to various parts of the cooling water system and block the pipes. Since the paste formed by solid powder is mixed with microbial slime, it is often misdiagnosed as microbial slime. The paste formed by solid powder adheres to the pipes of the cooling water system for a long time, causing corrosion and perforation of the heat exchanger. The production materials in the heat exchanger will enter the cooling water and quickly corrode the metal, causing the original water treatment agent to fail, a large amount of biological slime to deposit, and a sharp increase in operating costs.

[0007] Finally, the open cooling tower will evaporate a large amount of water and heat and blow it into the atmosphere, which consumes a lot of water in water-scarce areas. The bactericidal and anti-scaling agents used in the open cooling tower, as well as the agents used for regular descaling and cleaning, and the concentrated water discharged will put pressure on the environment. The heat exchange interface of the open cooling tower always deviates from the optimal heat transfer state during the scaling and descaling cycle, with large thermal resistance, wasting heat energy and circulation kinetic energy. Due to the severe corrosion of metals by the under-scaling corrosion and descaling operations of the open cooling tower, the safe service life of the equipment is shortened, and the hidden dangers of the entire circulating water system are superimposed.

[0008] In summary, due to the contact between the circulating water and air inside the open cooling tower, a large amount of suspended matter and biological sludge are deposited in the system, and corrosive paste-like substances adhere to it for a long time, which affects the normal operation of the equipment and shortens the safe service cycle of the equipment. In addition, the open cooling tower has a large water resource loss and consumes a lot of water in water-scarce areas. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0043] The following further describes the present invention in detail with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

[0044] Embodiment 1

[0045] Please refer to Figure 1 , Figure 1 FIG. is a schematic structural diagram of a water-saving skid-mounted cooling system provided by an embodiment of the present invention.

[0046] A water-saving skid-mounted cooling system provided in this embodiment includes: a circulating water tank 1, a heat exchange unit, and a skid-mounted base 5. Among them, the circulating water tank 1 and the heat exchange unit are both arranged on the skid-mounted base 5. The inside of the circulating water tank 1 is divided into a hot water chamber, a heat exchange chamber, and a cold water chamber. The hot water chamber, the heat exchange chamber, and the cold water chamber are arranged in sequence and communicate at the top. The cold water chamber is connected to the outlet of the heat exchange unit, and the heat exchange chamber is connected to the inlet of the heat exchange unit.

[0047] Specifically, the hot water chamber, the heat exchange chamber, and the cold water chamber are sequentially arranged along the axial direction of the circulating water tank 1. The hot water chamber is used to carry the hot water to be cooled by the external system, and the cold water chamber is used to carry the cooling water provided by the heat exchange unit. When the external system needs to be cooled, the cooling system is moved to the hot water outlet of the external system by moving the skid-mounted base 5, and the hot water outlet of the external system is connected to the hot water chamber, so that the hot water to be cooled enters the hot water chamber. The heat exchange unit is turned on, and the heat exchange unit injects cooling water into the cold water chamber. Since the tops of the hot water chamber, the cold water chamber, and the heat exchange chamber are connected, after the cooling water and the hot water to be cooled reach a certain height, they will flow into the heat exchange chamber from the tops of the hot water chamber and the cold water chamber respectively and mix in the heat exchange chamber to achieve heat exchange. This cooling system operates in a closed manner, which can avoid the contact between the circulating water and the atmospheric interface, thereby preventing a large amount of external substances from depositing or adhering in the system, ensuring the normal operation of the equipment, increasing the safe service life of the equipment. This cooling system can isolate the interference of sunlight and the atmosphere, prevent the circulating water from being blown away and evaporated, save water resources, and is suitable for use in water-scarce areas and for clean operation in closed workshops. It should be understood that when the cooling system starts to operate for the first time, cold water with the same composition as the hot water to be cooled can be injected into the heat exchange unit as the cooling water, or a large amount of hot water to be cooled can be directly injected into the hot water chamber, so that the hot water to be cooled flows through the heat exchange chamber into the heat exchange unit and forms cooling water after being cooled by the heat exchange unit.

[0048] In this embodiment, a first overflow plate 105 and a second overflow plate 106 are sequentially arranged along the axial direction inside the circulating water tank 1. The bottom of the first overflow plate 105 and the bottom of the second overflow plate 106 are both hermetically connected to the circulating water tank 1. An overflow channel is formed between the top of the first overflow plate 105 and the inner wall of the circulating water tank 1 and between the top of the second overflow plate 106 and the inner wall of the circulating water tank 1. The side of the first overflow plate 105 away from the second overflow plate 106 is the hot water chamber, and the side of the second overflow plate 106 away from the first overflow plate 105 is the cold water chamber. The heat exchange chamber is located between the first overflow plate 105 and the second overflow plate 106.

[0049] Specifically, the first overflow plate 105 and the second overflow plate 106 are sequentially arranged along the axial direction inside the circulating water tank 1. Both the first overflow plate 105 and the second overflow plate 106 are circular plates with a part of the top cut off. The arc edges of the first overflow plate 105 and the second overflow plate 106 are hermetically connected to the inner wall of the circulating water tank 1, dividing the inside of the circulating water tank 1 into a hot water chamber, a heat exchange chamber, and a cold water chamber in sequence. The part of the top cut off from the first overflow plate 105 and the second overflow plate 106 forms an overflow channel. In this embodiment, there is a 20-cm gap between the tops of the first overflow plate 105 and the second overflow plate 106 and the circulating water tank 1, forming an overflow channel, so that the hot water to be cooled and the cooling water can overflow smoothly into the heat exchange chamber. In an implementable manner, the bottom of the first overflow plate 105 and the bottom of the second overflow plate 106 are both welded to the circulating water tank 1.

[0050] In this embodiment, the heat exchange unit includes: a refrigeration circulation pump 2, a heat exchanger 3, and a refrigerator 4. Among them, the interior of the heat exchanger 3 has a first circuit and a second circuit. The inlet of the first circuit is connected to the heat exchange chamber through the refrigeration circulation pump 2, and the outlet of the first circuit is connected to the cold water chamber. The inlet of the second circuit is connected to the outlet of the refrigerator 4, and the outlet of the second circuit is connected to the inlet of the refrigerator 4.

[0051] In this embodiment, a hot water inlet 101 is provided at the top of the hot water chamber, a cold water outlet 102 is provided at the bottom of the cold water chamber, and a cold water inlet 104 is provided at the top of the cold water chamber. A warm water outlet 103 is provided at the bottom of the heat exchange chamber.

[0052] Specifically, the hot water to be cooled by the external system flows from the hot water inlet 101 into the hot water chamber. The cold water inlet 104 is connected to the outlet of the first circuit in the heat exchanger 3, and the warm water outlet 103 is connected to the inlet of the refrigeration circulation pump 2. The warm water after heat exchange in the heat exchange chamber sequentially passes through the warm water outlet 103, the refrigeration circulation pump 2, and the inlet of the first circuit in the heat exchanger 3 and enters the first circuit in the heat exchanger 3. The refrigeration medium in the refrigerator 4 enters the second circuit of the heat exchanger 3. The refrigeration medium in the second circuit exchanges heat with the warm water in the first circuit, cools the warm water to form cooling water, and then the refrigeration medium is recycled back to the refrigerator 4 for cooling. The cold water outlet 102 is connected to the external system. Part of the cooling water in the cold water chamber overflows into the heat exchange chamber for heat exchange, and the other part is output from the cold water outlet 102 to the external system.

[0053] In this embodiment, a pressure safety relief port 108, a nitrogen injection port 109, and a pressure gauge 110 are provided at the top of the circulating water tank 1. A maintenance manhole 117 is provided on the side wall of the circulating water tank 1.

[0054] Furthermore, the pressure safety relief port 108, the nitrogen injection port 109, and the pressure gauge 110 are sequentially arranged along the axis of the circulating water tank 1 between the hot water inlet 101 and the cold water inlet 104.

[0055] Specifically, the pressure safety relief port 108 and the nitrogen injection port 109 are both provided at the top of the heat exchange chamber, and the pressure gauge 110 is provided at the top of the cold water chamber. The nitrogen injection port 109 is used to introduce nitrogen into the system to expel the air in the system, realize an inert gas environment in the circulating water system, reduce oxygen corrosion, and interfere with miscellaneous gases such as carbon dioxide. The pressure safety relief port 108 is used to adjust the pressure of the system so that the interior of the circulating water tank 1 operates at 0.1 MPa to 0.2 MPa, which helps to reduce the gasification of the circulating water, improve the heat transfer efficiency, avoid the precipitation and scaling of the mineral concentration in the interfacial microbubbles exceeding the dissolution limit, and reduce the micro-leakage corrosion of the circulating water system and balance the system pressure difference. In addition, pressurizing the interior of the circulating water tank 1 can also monitor the system leak points in real time during the operation of the system and reduce accidents.

[0056] In this embodiment, a sewage outlet 107 is provided at the bottom of the hot water chamber, and a hot water thermometer 111 and a hot water level gauge 112 are provided on the side wall of the hot water chamber. A warm water thermometer 113 and a warm water level gauge 114 are provided on the side wall of the heat exchange chamber. A cold water thermometer 115 and a cold water level gauge 116 are provided on the side wall of the cold water chamber.

[0057] Specifically, the sewage outlet 107 is used to discharge the dirt deposited in the hot water chamber, and the thermometers and level gauges are used to monitor the conditions of the liquids in each chamber. In addition, the level gauge can also be used to find system leakage points.

[0058] Preferably, the heat exchanger 3 is a U-tube heat exchanger. Optionally, the heat exchanger 3 is made of 304 stainless steel. The heat exchanger 3 is elevated by a bracket, or the heat exchanger 3 is a vertical heat exchanger to reduce the floor area of the system. The refrigerator 4 is arranged at the end of the skid-mounted base 5. The refrigerator 4 is a heat pump, and its heat energy can be directly dissipated into the atmospheric environment or the high-quality heat energy can be recycled and conducted into the workroom for heating or material heating. Inner-packed filler screens are provided inside both the hot water inlet 101 and the cold water inlet 104. The inner-packed filler screen can prevent the hot water to be cooled and the cooling water from bringing solid impurities into the circulating water tank 1. Optionally, the material of the inner-packed filler screen is brass, which can precipitate trace amounts of zinc elements for sacrificial anode protection of the circulating water tank 1 through the principle of microdissolution and electrocoupling, and precipitate trace amounts of copper elements to protect the coatings in all areas in contact with the circulating water from scaling, corrosion and sterilization.

[0059] In this embodiment, the water-saving skid-mounted cooling system further includes: a ladder 6 and an upper platform 7. Among them, the ladder 6 is fixedly arranged on the skid-mounted base 5 and is located on one side of the circulating water tank 1. The upper platform 7 is arranged on the top of the circulating water tank 1 and is fixedly connected to the circulating water tank 1 and the ladder 6.

[0060] Specifically, the upper platform 7 is used for the maintenance or operation of the hot water inlet 101, the cold water inlet 104, the pressure safety relief port 108, the nitrogen injection port 109 and the pressure gauge 110, and the ladder 6 connects the upper platform 7 and the skid-mounted base 5 together.

[0061] The water-saving skid-mounted cooling system provided in this embodiment has three circulating liquid circuits, namely: an external heat exchange circuit, an internal heat exchange circuit, and a refrigeration circuit. The hot water to be cooled in the external system enters the cooling system through the hot water inlet 101, and the cooling water of the cooling system is output to the external system through the cold water outlet 102, forming the external heat exchange circuit. The hot water to be cooled and the cooling water are mixed in the heat exchange chamber to form warm water. The warm water flows from the warm water outlet 103 to the refrigeration circulation pump 2, and under the action of the refrigeration circulation pump 2, enters the first circuit in the heat exchanger 3. After exchanging heat with the refrigeration medium in the second circuit of the heat exchanger 3, it is cooled to form cooling water, and flows into the circulating water tank 1 through the cold water inlet 104, forming the internal heat exchange circuit. The low-temperature cooling medium in the refrigerator 4 enters the second circuit in the heat exchanger 3 from the outlet of the refrigerator 4. After the low-temperature cooling medium exchanges heat, its temperature rises and becomes a high-temperature cooling medium. The high-temperature cooling medium returns to the refrigerator 4 from the outlet of the second circuit in the heat exchanger 3, forming the refrigeration circuit.

[0062] The usage method of the water-saving skid-mounted cooling system provided in this embodiment includes the following steps:

[0063] S1: Transport the water-saving skid-mounted cooling system of this embodiment to the vicinity of the external application system, and arrange the skid-mounted base 5 on a flat ground. Weld the hot water inlet 101 to the hot water pipeline outlet of the external system, and weld the cold water outlet 102 to the water inlet pipeline of the external system.

[0064] S2: After cleaning the inside of the cooling system, under the open mode of the bypass valve at the pressure safety relief port 108, inject water into the circulating water tank 1 through the external system until the hot water level gauge 112, warm water level gauge 114, and cold water level gauge 116 all show close to the upper limit.

[0065] S3: Open the valve at the warm water outlet 103 to connect the refrigeration circulation pump 2 and the heat exchanger 3.

[0066] S4: Start the refrigerator 4 to enable the cooling medium and the warm water to exchange heat in the heat exchanger 3, and judge the refrigeration effect according to the change of the cold water thermometer 115.

[0067] S5: Open the valve at the cold water outlet 102 to make the cooling system work normally. During the operation of the cooling system, the circulating water tank 1 can be moderately replenished with water to make up for the water volume accommodation of the entire system pipeline in the cooling system.

[0068] S6: Inject nitrogen through the nitrogen injection port 109. After the bypass valve of the pressure safety relief port 108 has been open for 10 minutes, close the bypass valve. After the pressure safety relief port 108 has operated normally, stop injecting nitrogen and close the nitrogen injection port 109. When the pressure gauge 110 has dropped to 0.1 MPa, check whether there are any leakage points in the cooling system. After confirming that there are no leakage points, repeat the nitrogen injection until the pressure safety relief port 108 operates normally at 0.2 MPa. When there are no requirements for the composition of the cooling water in the external system, methanol, ethylene glycol, or commercial freezing liquid can be used instead of water in the circulating water tank 1 to adapt to the operation of the circulating water system at sub-zero low temperatures.

[0069] S7: After the cooling system has been initially operated for 1 hour, open the drain port 107 for draining, and then check the scale accumulation in the circulating water tank 1 every month. Open and check the internal packed screen in the hot water inlet 101 and the cold water inlet 104 once a year to replenish and update the internal packing. Check whether the first overflow plate 105 and the second overflow plate 106 are intact through the maintenance manhole 117 once a year.
