[0002] The function of the anti-scaling evaporative condenser is to remove impurities in water vapor, prevent pipe blockage, and improve the operating efficiency and service life of the system.

[0003] Although current technology has many advantages, its disadvantage is that because the condenser is in a closed state, when scaling occurs in the condenser, it is difficult for staff to determine the internal scaling situation. As a result, when scaling is discovered inside the condenser, a large area of ​​scaling has already occurred inside, which increases the difficulty of cleaning and the workload of employees. At the same time, some non-condensable gases will be discharged from the condenser, and this part of the gas contains harmful gases that pollute the environment. This part of the gas is directly discharged into the atmosphere, which will cause atmospheric pollution and does not meet the national zero emission standards. Utility Model Content

At the same time, some non-condensable gases will be discharged from the inside of the condenser, and this part of the gas contains harmful gases that pollute the environment. This part of the gas is directly discharged into the atmosphere, which will cause atmospheric pollution and does not meet the national zero emission standards.

[0014] 1. The utility model introduces steam into the condenser through an air inlet pipe, introduces cooling water into a water inlet pipe, then enters each cooling water pipe through the water inlet pipe, and finally is led out through a cooling water return pipe.

In terms of cleaning scaling, the work intensity of employees is reduced and the service life of the condenser 1 is increased.

[0024] like Figure 1-4 As shown, the top of the purification box 15 is fixedly connected with an exhaust pipe 16, and the outer surface of the purification box 15 is fixedly connected with a connecting pipe 14, which prevents harmful gases from entering the atmosphere, protects the environment, and ensures the health of employees.

[0025] like Figure 1-4 As shown, a water level gauge 2 is fixedly connected to the outer surface of the condenser 1, and an air inlet pipe 3 is fixedly connected to the top of the condenser 1. The water level gauge 2 can reflect the liquid level in the condenser 1, thereby preventing the liquid level in the condenser 1 from being too high or too low and affecting the normal operation of the equipment.

[0026] like Figure 1-4 As shown, a water outlet pipe 4 is fixedly connected to the bottom of the condenser 1, and a plurality of rotating shafts 9 are movably embedded in the inner surface of the condenser 1.

The water level gauge 17 can monitor the liquid level in the water tank 13 to prevent the water level in the water tank 13 from being too high and entering the condenser 1 and the purification tank 15, thereby ensuring the normal operation of the system.

[0029] like Figure 1-4 As shown, a drain pipe 19 is fixedly connected to one side of the water tank 13 near the bottom, and the cooling water return pipe 7 and the water inlet pipe 6 are fixedly connected to the outer surfaces of the plurality of cooling water pipes 5.

When the internal scale of the multiple cooling water pipes 5 is less, the multiple fan blades 11 rotate fast, and when the internal scale of the multiple cooling water pipes 5 is more, the multiple fan blades 11 rotate slowly. The scaling of the cooling water pipes 5 inside the condenser 1 can be reflected by the rotation speed of the multiple fan blades 11. The water level gauge 2 can reflect the liquid level in the condenser 1. The condensed water in the condenser 1 is discharged from the outlet pipe 4, which avoids the failure to timely discover the serious scaling of the cooling water pipes 5, causing the vacuum of the condenser 1 to drop seriously, so that the connecting pipe of the condenser 1 The steam leakage in the pipeline endangers the health of the on-site personnel and also wastes a lot of heat energy. In terms of cleaning the scaling, the work intensity of the employees is reduced and the service life of the condenser 1 is increased. The condenser 1 discharges the non-condensable gas and the gas that cannot be condensed in time to the connecting pipe 12, and the connecting pipe 12 guides this part of the gas into the water tank 13. The gas that cannot be condensed in time will be condensed in the water tank 13, and the non-condensable gas will continue to enter the purification box 15 through the connecting pipe 2 14.

The water level gauge 2 17 can reflect the water level in the water tank 13, the water supply pipe 18 can replenish water in the water tank 13, and the drain pipe 19 can discharge excess water when the water level in the water tank 13 is too high.
