[0023] Further, the inner wall surface of the shell 1 is coated with a corrosion-resistant coating, which is a high-temperature-resistant, acid-resistant and alkali-resistant epoxy resin coating. The corrosion-resistant coating can effectively protect the shell 1 from corrosion by steam and condensate. The shell 1 effectively resists corrosion by steam and condensate, prolongs the service life of the shell 1, ensures the structural integrity of the device, reduces the risk of leakage caused by corrosion of the shell, and ensures the safe and stable operation of the entire condensation process.
[0024] Further, the anti-skid lines 2 are arranged on the outer wall surface of the shell 1 in multiple groups and symmetrically about the central axis of the shell 1. The anti-skid lines 2 facilitate the operator to grip the shell 1 when installing, maintaining or moving the device, prevent the hands from slipping, and improve the convenience and safety of operation. In particular, in scenarios requiring manual operation such as maintenance of the device, the anti-skid lines 2 can effectively reduce the possibility of equipment damage or personal injury caused by accidental slipping.
[0025] Further, multiple groups of connecting plates 8 are arranged at equal intervals inside the shell 1, and multiple groups of tube bundles 9 are arranged on the surface of the connecting plates 8. The connecting plates 8 and the tube bundles 9 increase the contact area and contact time of steam and cooling medium, improve the heat exchange efficiency, enable the steam to be more fully condensed, and improve the working efficiency of the entire condensation device, which helps to meet the requirements for condensation effect under different working conditions.
[0026] Further, the tube bundles 9 are designed to be detachable and replaceable, and their two ends are connected to the connecting plates 8 through quick connection joints. When the tube bundles 9 fail or are heavily scaled, they can be quickly replaced or cleaned without the need to disassemble the entire device. This greatly shortens the maintenance time, reduces the maintenance workload, reduces the equipment downtime caused by maintenance, improves the production efficiency, and reduces the risk of damage to other components during maintenance, thereby reducing the maintenance cost.
[0027] Further, the threaded block 1001 and the threaded groove 1002 have high screwing precision, and the threaded surfaces are subjected to corrosion-resistant treatment to prevent loosening caused by corrosion during long-term use. The threaded block 1001 and the threaded groove 1002 ensure the tightness and stability of the connection between the upper end cover 3, the lower end cover 6 and the shell 1, prevent steam or condensate from leaking, and effectively prevent the threaded surfaces from being corroded by long-term contact with corrosive media, thereby avoiding loosening caused by corrosion of the threaded surfaces and ensuring the structural reliability of the device during long-term operation and maintaining a normal condensation working environment.
[0028] Further, the shape of the limiting block 1006 matches the shape of the limiting hole 1007, and the end of the limiting block 1006 is provided with a rubber buffer pad, which enhances the connection stability while reducing the impact force during connection. Through the setting of the limiting block 1006 and the limiting hole 1007, the installation position of the upper end cover 3 and the lower end cover 6 can be accurately positioned when the limiting block 1006 is inserted into the limiting hole 1007, enhancing the connection stability and preventing misplacement or loose connection of the components due to improper installation. The rubber buffer pad absorbs the impact force during connection, reducing damage to the components caused by collisions during installation, further improving the durability and reliability of the device, prolonging the overall service life of the equipment, and reducing the frequency and cost of equipment maintenance.
[0029] Working principle: First, during operation, steam enters the inside of the shell 1 from the gas inlet 4 and flows around the tube bundle 9. At the same time, the cooling medium enters from the cooling medium inlet and outlet 5 and circulates inside the tube bundle 9. Because the temperature of the steam is higher than that of the cooling medium, heat is transferred from the steam to the cooling medium through the tube wall of the tube bundle 9. After losing heat, the steam undergoes a phase change and condenses into a liquid, flowing down the outer wall of the tube bundle 9 and eventually being discharged from the liquid outlet 7. During the contact between the steam and the tube bundle 9, if the steam contains impurities or solutes, they may adhere to the surface of the tube bundle 9 and form a scale layer. However, due to the detachable design of the tube bundle 9, when the scale layer accumulates to a certain extent and affects the heat exchange efficiency, it can be easily removed from the connecting plate 8 for cleaning or replacement, ensuring the continuous and efficient operation of the equipment. The shell 1 has a corrosion-resistant coating on its inner wall to resist the corrosion of steam and condensed liquid, maintain its structural stability, and prevent steam or condensed liquid leakage caused by corrosion, thereby ensuring a safe environment for the entire condensation process. The multiple sets of equally spaced connecting plates 8 cooperate with the tube bundle 9 to maximize the heat exchange area and time between the steam and the cooling medium, effectively improving the condensation efficiency and enabling the device to adapt to different working conditions. The upper end cover 3 and the lower end cover 6 are tightly connected to the shell 1 through the connecting and limiting mechanism 10. During installation, the precise cooperation of the threaded block 1001 and the threaded groove 1002, as well as the accurate positioning of the limiting block 1006 and the limiting hole 1007, ensures the tightness and stability of the connection. At the same time, the rubber buffer pad reduces the impact force during installation, protecting the components from damage. During the long-term operation of the equipment, the corrosion-resistant treatment of the threads prevents connection loosening caused by corrosion, ensuring the reliability of the device structure. The anti-slip pattern 2 on the outer wall of the shell 1 facilitates safe and convenient manual operation during equipment installation, maintenance, and movement, reducing the risk of accidents caused by improper operation and further improving the overall practicality and reliability of the equipment. The entire steam-type scraper evaporator condensing device can stably and efficiently complete the steam condensation work, meeting the related needs in industrial production. Thus, the use process of a steam-type scraper evaporator condensing device is completed.
