Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a steam recovery device for cooling towers. Background Technology

[0002] Cooling towers are indispensable heat exchange equipment in industrial production and civil buildings. Their core function is to transfer the heat from high-temperature cooling water (or other heat transfer media) discharged from industrial systems (such as steam turbines, reactors, and refrigeration units) to the atmosphere through direct or indirect contact between air and water, thereby reducing the water temperature to within the range required by the process and enabling the recycling of cooling water. As the "terminal heat dissipation hub" of industrial circulating water systems, cooling towers are widely used in power, chemical, steel, pharmaceutical, and data center industries.

[0003] However, during the heat dissipation process, cooling towers generate a large amount of low-temperature steam with a temperature of 30℃-80℃. Since this type of steam is harmless to the environment, it is usually directly released into the air. However, this type of steam carries a large amount of latent heat that is not effectively recovered, resulting in energy waste. Utility Model Content

[0004] The purpose of this invention is to provide a steam recovery device for cooling towers, which can use the waste heat of steam to heat the cold water inside the spiral tube, thereby reducing energy waste. It can also collect the condensate generated by the steam contacting the spiral tube for recycling, thus improving practicality. At the same time, it can cause the spiral tube to vibrate slightly, thereby facilitating the collection of condensate.

[0005] To achieve the above objectives, a steam recovery device for cooling towers is provided, comprising:

[0028] Those skilled in the art should connect all electrical components in this case to their compatible external power supply via wires, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0029] Working principle: During operation, the low-temperature steam generated by the base 1 is sent into the processing tank 6 through the exhaust port 3, the gas collecting head 4, and the gas pipe 5. Simultaneously, the water pump 8 and motor 15 are activated. Under the action of the water pump 8, external cold water is absorbed through the liquid inlet pipe 9 and then transported through the spiral tube 10 for use. The low-temperature steam entering the processing tank 6 comes into contact with the spiral tube 10, heating the cold water inside to meet hot water needs and reduce energy waste. Simultaneously, when the low-temperature steam comes into contact with the cool spiral tube 10, it condenses into water, which falls to the bottom of the processing tank 6 for storage, and the second shut-off valve is opened. The condensate can be drained through the drain pipe 12 for use, thereby further saving energy. Under the action of the motor 15, the rotating shaft 16 drives the sector gear 17 to rotate. Then, under the meshing action of the sector gear 17 and the toothed plate 21, the square rod 18 moves to the left. At the same time, under the action of the motor 15, the spring 24 is compressed. When the toothed part on the sector gear 17 disengages from the toothed plate 21, the square rod 18 moves to the right under the action of the spring 24 and hits the spiral tube 10 through the rubber block 19, causing it to vibrate so that the condensate attached to the spiral tube 10 can fall off quickly and assist in collection.
