Description

Technical Field

[0001] The utility model relates to the technical field of boiler heating, and more specifically to a uniform heating structure for a double water-cooled smoke box vacuum boiler. Background Art

[0002] The uniform heating structure of the double water-cooled smoke box vacuum boiler mainly refers to a special design inside the boiler, which is designed to ensure that the heating process inside the furnace is more uniform and efficient. The basic structure and working principle of the double water-cooled smoke box vacuum boiler. This boiler usually includes a combustion chamber and a heat exchanger, which are connected by a flue. The combustion of fuel in the combustion chamber generates heat, which is transferred to the heat exchanger through the flue to heat the working medium (such as water). The key here is to ensure that the heat is evenly distributed throughout the heat exchanger to avoid local overheating or overcooling.

[0003] Among them, it was found through searching that the patent application number CN202322782416.0 discloses a new type of electric heating vacuum boiler, including a boiler body, a side wall of the boiler body is fixedly connected to an assembly shell, the bottom of the assembly shell is fixedly connected to a connecting shell, the inner wall of the boiler body is fixedly connected to an electric heating pipe, the surface of the boiler body is fixedly connected to a liquid inlet pipe, the side wall of the liquid inlet pipe is fixedly connected to a liquid inlet valve, and the back of the boiler body is connected to a pumping assembly;

[0004] When the structure is in use, the heated wind is blown by the second connecting fan blade, which facilitates the wind to accelerate the movement inside the assembly shell and collide with the surface of the assembly serpentine tube, thereby further conduction heating the surface of the assembly serpentine tube, and then the wind with continuous heat transfer is discharged into the installation serpentine tube through the first installation branch pipe, thereby conduction heating the liquid inside the boiler body, so that it has a pretreatment structure and also quickly heats the liquid. At the same time, the waste heat is reused to reduce the waste of thermal energy, thereby improving the use effect. However, when in use, the structure is not easy to borrow the heat when the boiler smoke is discharged, resulting in a faster heat loss rate of the device during heat conduction, affecting the heating efficiency and effect.

The flue gas is filtered by the filter 7 to reduce the dust content of the flue gas entering the heat exchange area 8. At the same time, when the high-temperature flue gas enters the heat exchange area 8, the flue gas contacts each heat exchange tube 11 and heats the heat exchange tube 11 through the high-temperature flue gas. When the high-temperature flue gas is discharged upward, it is easy for each heat exchange tube 11 to contact the high-temperature flue gas, thereby ensuring that the heat is evenly distributed and efficiently transferred inside the entire heat exchange area 8. The specific structure of the assembly is arranged as follows;

[0023] The flow-conducting heating assembly comprises a furnace body 2 disposed in a reinforced shell 1, a burner 3 is disposed at the bottom of the furnace body 2, a first conduit 4 is disposed on one side of the surface of the burner 3, the first conduit 4 is connected to the burner 3, and a first fan 5 is disposed at one end of the first conduit 4;

At the same time, when the high-temperature flue gas enters the heat exchange zone 8, the flue gas contacts each heat exchange tube 11 and heats the heat exchange tube 11 through the high-temperature flue gas. When the high-temperature flue gas is discharged upward, it is easy for each heat exchange tube 11 to contact with the high-temperature flue gas, thereby ensuring that the heat is evenly distributed and efficiently transferred inside the entire heat exchange zone 8.
