[0002] The waste heat recovery cooling tower is a device that uses a heat exchanger to recover the waste heat of the cooling water in the cooling tower. During the operation of the cooling tower, the cooling water circulates continuously and absorbs a large amount of heat generated by the machine, becoming hotter and hotter. Before returning to the cooling tower, the waste heat in the cooling water can be exchanged with other recovery media by using a heat exchanger, thereby recovering the waste heat.

[0003] Existing waste heat recovery cooling towers generally use waste heat recovery pipes to exchange heat between steam and cooling media. At the same time, during the transportation process of waste steam, the waste steam will pass through a large number of pipes and equipment, which will cause the waste steam to carry more impurities. When the waste steam comes into contact with the waste heat recovery pipe, some of the impurities will accumulate on the waste heat recovery pipe.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe 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.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A waste steam waste heat recovery cooling tower comprises a cooling tower shell 1, which is divided into two chambers by a partition plate 2, and the cooling tower shell 1 is connected to two air pipes 3 connected to a steam delivery pipe, and the cooling tower shell 1 is connected to two water pipes 4 connected to a cooling water source, the two chambers are divided by the partition plate 2, and the two chambers are arranged up and down, and the two air pipes 3 are located at the input end and output end of the upper chamber, so that steam can enter the cooling tower shell 1, and the water pipe 4 is located at the input end and output pipe of the lower chamber, wherein a part of the water pipes is connected to an external water source, and the number of this part of the water pipes is multiple, and they are distributed at the bottom of the cooling tower shell 1, and another water pipe is connected to an external water source pipe that has been heated and treated, so that the treated water source can be discharged from the other water pipe.

[0031] Reference Figure 3A plurality of waste heat recovery pipes 5 that can be rotated by a rotating member 7 are provided in the cooling tower shell 1, and the plurality of waste heat recovery pipes 5 are connected with conductive members 8, and the lower ends of the plurality of conductive members 8 extend to the bottom of the partition plate 2, respectively, and a plurality of scrapers 6 are connected to the partition plate 2, and the plurality of scrapers 6 are in contact with the side walls of the plurality of waste heat recovery pipes 5, respectively.

[0032] Therefore, when the waste heat recovery pipe 5 rotates, the waste heat recovery pipe 5 can make a circular motion. At the same time, since the scraper 6 is located on one side of the waste heat recovery pipe 5 and the scraper 6 is in contact with the side wall of the waste heat recovery pipe 5, when the waste heat recovery pipe 5 rotates, the impurities on the waste heat recovery pipe 5 can be cleaned up, and the heat exchange efficiency of the waste heat recovery pipe 5 can be further guaranteed, avoiding the waste heat recovery pipe 5 from having a relatively low waste heat absorption efficiency due to surface impurities, thereby further reducing the waste heat recovery efficiency of the device.

[0033] Reference Figure 4 , Figure 5 and Figure 6 The rotating member 7 includes a plurality of vertical rods 71 ​​fixedly connected to the bottom of the cooling tower shell 1, the upper ends of the plurality of vertical rods 71 ​​are fixedly connected to the same shell 72, and a portion of the water pipe 4 is connected to the shell 72, a rotating rod 73 is passed through the shell 72, a blade 74 is coaxially fixedly connected to the side wall of the rotating rod 73, and the blade 74 is in the shell 72, a cross plug 76 is fixedly connected to the upper end of the rotating rod 73, and a cross slot 75 matching the cross plug 76 is provided at the lower end of the waste heat recovery pipe 5, and the upper end of the cross plug 76 extends into the cross slot 75.

[0034] It is particularly noteworthy that a part of the water pipe 4 is divided into multiple water inlet pipes and multiple water outlet pipes, one of the water inlet pipes is connected to an external water source pipe, and one of the water inlet pipes is connected to the input end of one of the shells 72, so that the water source can enter one of the shells 72, and secondly, one of the water outlet pipes is connected to another shell 72, so that the water source entering one of the shells 72 can enter the next shell 72, so that the water source can be reused, and then the water source enters the cooling tower shell 1 to meet the normal use requirements of the device.

[0035] In actual operation, when water enters the shell 72 from the water inlet pipe, the water can impact the blades 74, and further the rotating rod 73 can be rotated, so that the cross plug 76 can be rotated. At this time, the cross plug 76 is inserted into the waste heat recovery pipe 5. Therefore, when the cross plug 76 rotates, with the assistance of the cross slot 75, the waste heat recovery pipe 5 can rotate normally to ensure the normal use requirements of the device.

[0036] Reference Figure 4 , Figure 7 and Figure 8 The conducting member 8 includes a conducting tube 81 disposed below the waste heat recovery pipe 5, and the conducting tube 81 is below the partition plate 2, a mounting tube 82 is coaxially sleeved on the side wall of the conducting tube 81, a heat conducting tube 83 is provided at the connection between the mounting tube 82 and the conducting tube 81, a plurality of springs 84 are provided on the inner bottom of the mounting tube 82, and the upper ends of the plurality of springs 84 are connected to the same metal ring 85, a plurality of conducting rods 86 are fixedly connected to the lower end of the waste heat recovery pipe 5, and the lower ends of the plurality of conducting rods 86 extend into the mounting tube 82 respectively, the lower ends of the plurality of conducting rods 86 are fixedly connected to metal friction blocks 87 in contact with the metal ring 85, the side walls of the plurality of conducting rods 86 are fixedly connected to limiting blocks 88, and the side walls of the mounting tube 82 are provided with limiting grooves matching the limiting blocks 88.

[0037] In actual operation, when the waste heat recovery pipe 5 rotates, the conduction rod 86 can be rotated. When the conduction rod 86 rotates, the metal friction block 87 can be continuously rubbed on the metal ring 85, so that the metal ring 85 can generate a certain amount of heat, and further the heat can be conducted to the conduction tube 81 through the heat conduction tube 83, so that the conduction member 8 can generate a certain amount of heat. At the same time, it is particularly noteworthy that with the assistance of the spring 84, the metal ring 85 and the metal friction block 87 can fit together, further ensuring the normal use of the device. At the same time, it is particularly noteworthy that the steam heat absorbed by the waste heat recovery pipe 5 can be continuously transferred to the conduction tube 81 through the conduction rod 86, so that the water source under the partition plate 2 can be heated, and further the waste heat of the steam can be recovered and utilized.

[0038] Reference Figure 4 and Fig. 9 The conducting member 8 is firmly placed on the rotating member 7 through the closing member 9. The closing member 9 includes a closing seat 91 fixedly connected to the upper end of the shell 72. A closing groove 92 is provided in the closing seat 91.

The upper end of the closing ring 95 is connected to the lower end of the conducting tube 81, and a plurality of water stop grooves 96 are provided on the side wall of the closing ring 95.

[0039] In actual operation, when the staff inserts the waste heat recovery pipe 5 into the cooling tower shell 1, the closed ring 95 in the conduction tube 81 can enter the closed groove 92 in the closed seat 91, and the second rubber ring 94 can fit tightly on the first rubber ring 93. At the same time, it is particularly noted that when the second rubber ring 94 fits on the first rubber ring 93, since they are all made of rubber material, they will have a certain adsorption force, which can further achieve the purpose of stabilizing the conduction tube 81. At the same time, the cross-section of the water stop groove 96 on the closed ring 95 is an arc groove, which can effectively prevent the entry of water. In this way, the conduction tube 81 can be fixed, so that the waste heat recovery pipe 5 can rotate normally, which also ensures the stability of the conduction tube 81 and further ensures the normal use of the device.

[0040] Reference Figure 4 and Figure 7 A heating element 10 is provided in the conductive element 8, and the heating element 10 includes a magnetic ring 1001 arranged in the conductive tube 81, and one end of the rotating rod 73 passes through the side wall of the magnetic ring 1001 and extends upward.

[0041] In actual operation, when the rotating rod 73 rotates, the magnetic ring 1001 can be rotated. It is particularly noteworthy that the magnetism of the magnetic ring 1001 is strong. Therefore, when the magnetic ring 1001 rotates, since the copper ring 1002 is on one side of the magnetic ring 1001, the copper ring 1002 can be heated, and further the conductive tube 81 can generate a certain amount of heat, thereby increasing the efficiency of waste heat recovery.

[0042] Reference Figure 4 and Fig.11 A plurality of transmission members 11 connected to the waste heat recovery pipe 5 are provided in the cooling tower shell 1.

[0043] In actual operation, when the waste heat recovery pipe 5 rotates, the transmission rod 1101 can be rotated, and further the transmission disk 1102 can be rotated. When the transmission disk 1102 rotates, the first gear ring 1103 can be rotated, and further the second gear ring 1105 can be rotated. When the second gear ring 1105 rotates, the rotating rod 1106 can be rotated, so that other components can be used normally.

[0045] In actual operation, after the waste heat recovery pipe 5 has been used for a certain period of time, the staff can directly shut down the equipment and then drain the water source. Then the staff can directly rotate the cover 1202 through the rotating knob 1205, so that the cover 1202 can be taken out from the cover 1201. Then the staff can take the cover 1202 upwards, so that the waste heat recovery pipe 5 can be taken out from the cooling tower shell 1. It is particularly noteworthy that the parts connected to the waste heat recovery pipe 5 will also be taken out from the cooling tower shell 1, which further facilitates the staff to replace the waste heat recovery pipe 5, thereby facilitating the staff's work and indirectly improving the staff's work efficiency.

It is particularly noteworthy that a plurality of through holes are provided on the partition plate 2, and the diameter of the through holes is larger than the waste heat recovery pipe 5, so that impurities on the waste heat recovery pipe 5 can enter the bottom of the partition plate 2. At the same time, a drain pipe is provided at the bottom of the cooling tower shell 1, which can further discharge impurities. It is particularly noteworthy that the entry of steam into the bottom of the partition plate 2 will not cause the device to fail to operate, but will also lead to a better heat exchange effect of the device, and the diameter of the through hole at this location does not allow more steam to enter the bottom of the partition plate 2.

[0047] The first reciprocating screw rod 1302 is rotatably connected to the inner bottom of the cleaning box 1301, and the side wall of the first reciprocating screw rod 1302 is coaxially threadedly connected to the moving nut 1303.
