The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and also has a small number of applications in industrial production. A boiler that generates steam is called a steam boiler, often referred to as a boiler, and is mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises.

When the water vapor is recovered and recycled, the water vapor cooling time is often relatively long, resulting in reduced water vapor recovery efficiency and unsatisfactory boiler water recycling effect.

It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0020] like Figure 1 As shown, an inlet pipe 4 is inserted through the top end of the cooling circulation box 1, a circulation recovery pipe 3 is inserted through the bottom end of the cooling circulation box 1, one end of the circulation recovery pipe 3 is connected to a circulating water pump 2, a cooling water inlet pipe 5 is inserted into the front surface of the cooling circulation box 1, and a cooling water outlet pipe 11 is inserted into the rear surface of the inlet pipe 4.

[0021] As the preferred technical solution of this embodiment, Figures 2 to 4 As shown, a plurality of adjacent and parallel cooling plates 6 are installed inside the cooling circulation box 1, and a connecting water inlet pipe 10 is fixed to the end of the cooling water inlet pipe 5 near the cooling plate 6, and a connecting water outlet pipe 12 is fixed to the end of the cooling water outlet pipe 11 near the cooling plate 6. One end of the connecting water inlet pipe 10 and the connecting water outlet pipe 12 are both plugged in and the ends are in contact with each other. A temperature sensor 9 is fixed to the inner wall of the cooling circulation box 1, and the water vapor generated by the boiler is sent into the cooling circulation box 1 through the inlet pipe 4, so that the water vapor adheres to the outer surface of the cooling plate 6, and then the cooling water inlet pipe 5, the connecting water inlet pipe 10, the connecting water outlet pipe 12, and the cooling outlet pipe 11 circulate the coolant, and the cooling plate 6 is cooled by the circulating coolant, so that the water vapor is cooled on the outer surface of the cooling plate 6 and forms water droplets.

[0022] In this embodiment, support rods 14 are detachably installed on both sides of the top and bottom ends of the cooling plate 6. The two adjacent cooling plates 6 and the cooling plate 6 and the inner wall of the cooling circulation box 1 are connected by the support rods 14. The support rods 14 are used to suspend and support the cooling plate 6 to ensure that water vapor can flow freely between adjacent cooling plates 6.

[0023] Multiple cooling auxiliary plates 8 are fixed on both sides of the cooling plate 6, which are distributed in a linear array up and down. The cooling auxiliary plates 8 are inclined downward at a sixty-degree angle away from the side of the cooling plate 6. The cooling auxiliary plates 8 are added to the outside of the cooling plate 6 to increase the surface area of the cooling plate 6, so that water vapor can be better adsorbed, and the water droplets formed after the water vapor is cooled gather and slide down along the cooling auxiliary plates 8 and accumulate at the bottom end of the cooling circulation box 1, and are better transported to the boiler through the circulation recovery pipe 3 and the circulating water pump 2.

[0024] The end of the cooling auxiliary plate 8 near the cooling water inlet pipe 5 is penetrated and plugged with a diverter water inlet pipe 7, and the end of the cooling auxiliary plate 8 near the cooling water outlet pipe 11 is penetrated and plugged with a diverter water outlet pipe 13. The ends of the diverter water inlet pipe 7 and the diverter water outlet pipe 13 located in the cooling auxiliary plate 8 are in contact with each other, one end of the diverter water inlet pipe 7 is fixed and connected to the connecting water inlet pipe 10, and one end of the diverter water outlet pipe 13 is fixed and connected to the connecting water outlet pipe 12.

The temperature sensor 9 monitors the temperature inside the cooling circulation box 1. When the temperature inside the cooling circulation box 1 is high, the internal solenoid valves of the diverter water inlet pipe 7 and the end of the connecting water outlet pipe 12 are opened, so that the coolant transported in the cooling water inlet pipe 5 and the connecting water inlet pipe 10 enters the cooling auxiliary plate 8, and the water vapor accumulated inside the cooling circulation box 1 is auxiliary cooled by the cooling auxiliary plate 8.

[0025] Working principle: First, turn on the power of the device. After the power is turned on, the cooling water pump connected to the cooling water inlet pipe 5 transports the coolant into the cooling water inlet pipe 5. At this time, the coolant enters the connecting water inlet pipe 10 through the cooling water inlet pipe 5, and enters the connecting water outlet pipe 12 and the cooling water outlet pipe 11 through the connecting water inlet pipe 10. When the coolant flows in the connecting water inlet pipe 10 and the connecting water outlet pipe 12, the coolant can cool the cooling plate 6. At this time, the water vapor generated when the boiler is running is sent into the cooling circulation box 1 through the inlet pipe 4. After entering the cooling circulation box 1, the water vapor gathers in the cooling circulation box 1 and adheres to the outer surface of the cooling plate 6 As the coolant is cooling the cooling plate 6, the water vapor attached to the outer surface of the cooling plate 6 is cooled and forms water droplets. When the temperature inside the cooling circulation box 1 rises, the internal solenoid valves at the ends of the shunt water inlet pipe 7 and the connecting water outlet pipe 12 are opened, so that the coolant transported in the cooling water inlet pipe 5 and the connecting water inlet pipe 10 enters the cooling auxiliary plate 8, so that the cooling auxiliary plate 8 assists in cooling the water vapor accumulated inside the cooling circulation box 1. The cooling plate 6 is cooled by the circulating coolant, and the water vapor is assisted in cooling by the cooling auxiliary plate 8, thereby accelerating the cooling of the water vapor and improving the recycling efficiency of the boiler water.

It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
