Description

Technical Field

[0001] The invention relates to the field of cooling towers, in particular to a cooling tower used for ORC power generation. Background Art

[0002] The ORC power generation system is a Rankine cycle power generation technology that uses low-boiling point organic matter as a working fluid. It can convert low- and medium-grade waste heat generated in industrial production processes into high-grade electricity. In such a system, the cooling tower can cool the steam discharged from the turbine, condense it into liquid, and re-enter the system circulation.

[0003] When used in conjunction with an ORC power generation system, a cooling tower can improve cooling efficiency and ensure stable operation of the system, while also providing energy-saving and emission-reduction effects. The main heat source in an ORC system comes from the heat of the condenser tubes and cooling fins during the process of the condenser converting gas or steam into liquid, which can significantly increase the cooling requirements of the ORC. The ORC condenser is mainly cooled by air during cooling, and the cooling effect is not good. When used in conjunction with a cooling tower for cooling, the water in the cooling tower will contact the cooling fins of the condenser and cause rust, resulting in reduced heat dissipation for the condenser.

[0004] Therefore, a cooling tower for ORC power generation is proposed to solve the problem of poor cooling effect of the condenser. Summary of the invention

[0005] The object of the present invention is to provide a cooling tower for ORC power generation. By arranging rotating rods and cleaning brushes on both sides of the condenser, the cooling water adhering to the heat dissipation fins can be quickly detached, and the friction generated by the heat dissipation fins and the cleaning brush can effectively reduce the generation of scale, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cooling tower for ORC power generation, comprising a tower body and a condenser, wherein two ports of the condenser extend to the outside of the tower body, and is characterized in that a first dustproof net is fixedly connected to the upper side of the tower body and a fan is rotatably connected to the bottom end of the first dustproof net, a water supply tank is fixedly connected to the bottom end of the tower body, a partition is fixedly connected to the upper end of the water supply tank, a float liquid level compensator is fixedly connected to one side of the partition, a first water pump is fixedly connected to one side of the water supply tank, and an output end of the first water pump is located on the upper side of the partition, an air guide groove is opened on the tower body, an air guide frame is fixedly connected to the upper and lower sides of the tower body located at the air guide groove, a second dustproof net is fixedly connected to the bottom side of the air guide frame, and a support frame is fixedly connected to the tower body located in the air guide groove;

[0007] A second water pump is fixedly connected to one side of the upper end of the partition, a water delivery pipe is fixedly connected to the output end of the second water pump, four water collecting pipes are fixedly connected to the upper end of the water delivery pipe, a cross bar is fixedly connected to one side of the water collecting pipe, and an atomizing nozzle is evenly fixedly connected to the bottom end of the water collecting pipe;

[0008] A driving motor is fixedly connected to one side of the tower body, a rotating rod is fixedly connected to the output end of the driving motor, a cleaning brush is evenly fixedly connected to the rotating rod, and the cleaning brush corresponds to the heat dissipation fins of the condenser.

[0009] In a further embodiment, both sides of the tower body that are far away from each other are fixedly connected with inclined plates, and both sides of one side of the inclined plate are fixedly connected with grilles, and the grilles correspond to the air guide grooves. By setting the inclined plates and grilles, the fan can cause the air to form flocculation when providing guidance, thereby improving the cooling effect.

[0010] In a further embodiment, the two inclined plates are in an eight-shaped structure, and baffles are evenly and fixedly connected to the upper ends of the inclined plates. The baffles are in a V-shaped structure. By setting the baffles, the falling speed of the cooled water can be reduced in cooperation with the inclined plates, thereby reducing the impact of the return water on the water on the partition.

[0011] In a further embodiment, the inclined plate and the air guide frame have the same inclination, and leakage grooves are evenly opened on the upper end of the baffle plate. The leakage grooves on the baffle plate cooperate with the grille to further enhance the generation of flocculation.

[0012] In a further embodiment, the bottom ends of the two inclined plates are fixedly connected with a connecting cover, and the connecting cover is rotatably connected with a cutting blade. By providing the cutting blade, the falling water can be blocked and the contact between the water and the air can be improved.

[0013] In a further embodiment, clamping plates are fixedly connected to both sides of the inner wall of the tower body, and the cleaning brush contacts the clamping plates when the rotating rod rotates. By providing the clamping plates, the cleaning brush can be caused to vibrate to avoid water sticking.

[0014] In a further embodiment, a protrusion is evenly fixedly connected to the side of the card plate away from the condenser, and the protrusion is composed of a rectangular structure. By providing the protrusion, the unevenness of one side of the card plate is increased, so that when the cleaning brush rotates and contacts the card plate, multiple knocks can be generated, thereby achieving the effect of separating the water from the cleaning brush.

By providing the adaptation grooves, collision between the condenser port and the tower body can be avoided.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: by arranging the condenser in the tower body and using a driving motor to drive the rotating rod and the cleaning brush to rotate, the heat dissipation fins on the condenser are cleaned and dehydrated, thereby reducing the scale generated by the contact of water with the condenser, and promoting the separation of the cooling water stuck on the condenser, which can promote the contact between the condenser and the newly landed water, thereby improving the cooling effect of the condenser. At the same time, the inclined plate, baffle and rotating cutting blades are arranged, which can increase the time for the cooling water to fall on the partition, thereby preventing the cooling water from affecting the temperature of the bottom water.

DETAILED DESCRIPTION

[0025] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1

[0027] The condenser 14 is placed in the cooling tower body 1. When cooled by the water collecting pipe 11 and the atomizing nozzle 12, scale will be generated on the surface of the condenser 14. At the same time, water falls on the surface of the condenser 14 due to gravity, and the water falls off slowly.

[0028] See also Figure 1-6 The present embodiment provides a cooling tower for ORC power generation, including a tower body 1 and a condenser 14. The two ports of the condenser 14 extend to the outside of the tower body 1. A first dustproof net is fixedly connected to the upper side of the tower body 1 and a fan 2 is rotatably connected to the bottom of the first dustproof net. A water supply tank 3 is fixedly connected to the bottom of the tower body 1. A partition is fixedly connected to the upper end of the water supply tank 3. A water body is arranged on the partition. A float level compensator 4 is fixedly connected to one side of the partition. The float level compensator 4 can adjust the liquid level change by setting a connection between a float and a lever, a magnetic steel or the like. The tower body 1 is provided with an air guide groove 6, and the tower body 1 is fixedly connected with air guide frames 7 on both sides of the air guide groove 6, and the bottom side of the air guide frame 7 is fixedly connected with a second dustproof net, and the tower body 1 is located in the air guide groove 6 and is fixedly connected with a support frame 8, and the fan 2 can drive the air to enter the air guide groove 6 when it is started;

[0029] A second water pump 9 is fixedly connected to one side of the upper end of the partition, a water delivery pipe 10 is fixedly connected to the output end of the second water pump 9, four water collecting pipes 11 are fixedly connected to the upper end of the water delivery pipe 10, a cross bar 13 is fixedly connected to one side of the water collecting pipe 11, and an atomizing nozzle 12 is evenly fixedly connected to the bottom end of the water collecting pipe 11. The second water pump 9 pumps water through the water delivery pipe 10 and evenly sprays it onto the condenser 14 through the water collecting pipe 11 and the atomizing nozzle 12, thereby cooling the condenser 14;

[0030] A driving motor is fixedly connected to one side of the tower body 1, and a rotating rod 18 is fixedly connected to the output end of the driving motor. A cleaning brush 19 is evenly and fixedly connected to the rotating rod 18. The cleaning brush 19 corresponds to the cooling fins of the condenser 14. The output end of the driving motor drives the rotating rod 18 to rotate, so that the cleaning brush 19 can continuously contact the cooling fins of the condenser 14 and the conveying pipes wrapped by the cooling fins, thereby promoting the separation of scale and water on the cooling fins and the conveying pipes on the condenser 14.

[0031] Inclined plates 15 are fixedly connected to both sides of the tower body 1 that are far away from each other. Grilles 16 are fixedly connected to both sides of one side of the inclined plate 15. The grilles 16 correspond to the air guide grooves 6. The grilles 16 are used to block the air entering the tower body 1, so that the incoming air forms floccules, thereby providing an air cooling effect.

[0032] The two inclined plates 15 are in an eight-shaped structure, and a baffle 17 is evenly fixedly connected to the upper end of the inclined plate 15. The baffle 17 is in a V-shaped structure. By setting the V-shaped baffle 17, the falling water can be blocked and the falling speed of the water can be reduced, so that the cooling water can be prevented from directly contacting the water on the baffle, thereby reducing the impact of the temperature of the cooling water on the water on the baffle.

[0033] The inclined plate 15 has the same inclination as the air guide frame 7 . Leakage slots 22 are evenly formed on the upper end of the baffle 17 . The provision of the leakage slots 22 can cooperate with the grille 16 to further increase air flow.

[0034] The bottom ends of the two inclined plates 15 are fixedly connected with a connecting cover 23, and a cutting blade 24 is rotatably connected inside the connecting cover 23. By installing the cutting blade 24 between the two inclined plates 15, the falling cooling water can be blocked and the falling speed of the cooling water can be reduced.

[0035] The second water pump 9 draws water from the partition and transmits it to the water collecting pipe 11 through the water delivery pipe 10, and then sprays it evenly on the condenser 14 through the atomizing nozzle 12 to reduce the temperature of the condenser 14. At this time, the driving motor can drive the rotating rod 18 to rotate, and make the cleaning brush 19 constantly contact the heat dissipation fins on the surface of the condenser 14. The force of rotation can cause the water stuck on the condenser 14 to separate from the scale, and the cooling water continues to fall, and part of it falls on the inclined plate 15. After being blocked by the baffle 17, the speed of the water falling is reduced. At the same time, part of the cooling water falls into the gap between the two inclined plates 15, and then the cutting blade 24 rotates to disperse the cooling water and cause the cooling water to be reversely impacted to the other side of the inclined plate 15, so as to achieve the effect of reducing the falling of the cooling water. Then, the rotation of the fan 2 can draw outside air from the air guide groove 6 into the tower body 1, and can achieve the effect of reducing the temperature of the cooling water by contacting the cooling water, thereby preventing the cooling water from affecting the water temperature on the partition.

[0036] When the cleaning brush 19 is used to clean the condenser 14 , part of the water is easily adhered to the cleaning brush 19 , which makes the cleaning brush 19 inefficient in cleaning the water on the condenser 14 .

[0037] See also Figure 1 and 2 , further improvements are made on the basis of Example 1.

[0038] A clamping plate 20 is fixedly connected to both sides of the inner wall of the tower body 1. When the rotating rod 18 rotates, the cleaning brush 19 contacts the clamping plate 20. By setting the clamping plate 20 to provide a barrier on one side of the rotation direction of the cleaning brush 19, when the cleaning brush 19 contacts the clamping plate 20, it will be blocked by inertia and cause the cleaning brush 19 to vibrate, thereby prompting the water stuck on the cleaning brush 19 to be separated.

[0039] A protrusion 21 is evenly fixedly connected to the side of the card plate 20 away from the condenser 14. The protrusion 21 is composed of a rectangular structure. The protrusion 21 is provided to increase the unevenness of the card plate 20. The cleaning brush 19 will form a better vibration effect when bent, which can achieve the effect of cleaning the water on the condenser 14.

[0040] The cleaning brush 19 will collide with the card plate 20 when rotating. Since the brush body has the soft property, it will bend when contacting one side of the card plate 20, so it contacts the protrusion 21 on one side of the card plate 20. At the same time, the cleaning brush 19 has centrifugal force when rotating, thereby causing the water on the cleaning brush 19 to separate.

[0041] After the cooling water contacts the surface of the condenser 14 and cools down, small water droplets will condense into larger water droplets and fall down under gravity. At this time, the continuously falling water will contact the condenser 14, resulting in a reduction in the cooling effect.

[0042] See also Figure 1-6 , further improvements are made on the basis of Example 1.

[0043] A baffle 25 is fixedly connected to the outer side of the frame of the condenser 14, and an electric push rod 27 is fixedly connected to the upper end of the baffle 25. A connecting block 26 is fixedly connected to the output end of the electric push rod 27, and the connecting block 26 is fixedly connected in the tower body 1. The baffle 25 is driven to move back and forth by the electric push rod 27, and vibration is generated to separate the water stuck on the condenser 14.

[0044] Adaptation grooves 28 are provided on two sides of the tower body 1 that are away from each other. The adaptation grooves 28 correspond to the main ports of the condenser 14 . The adaptation grooves 28 are provided to avoid collision between the ports of the condenser 14 and the inner wall of the tower body 1 .

[0045] When the atomizing nozzle 12 sprays water and contacts the condenser 14 for cooling, the electric push rod 27 can extend and retract to make the condenser 14 shake linearly, thereby achieving the effect of causing the cooling water on the condenser 14 to separate, reducing the retention time of the water body and reducing the formation of scale.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
