Technical Field

[0001] The utility model belongs to the technical field of steam boilers, in particular to a steam boiler feed water energy-saving heating equipment. Background Art

[0002] A steam boiler refers to an industrial boiler that heats water to certain parameters and produces high-temperature steam. The water is heated in the drum and becomes steam, and the fire emits heat in the furnace. This is the principle of a steam boiler. The heating equipment (burner) releases heat, which is first absorbed by the water-cooled wall through radiation heat transfer. The water in the water-cooled wall boils and vaporizes, generating a large amount of steam that enters the steam drum for steam-water separation (except for direct current furnaces). The separated saturated steam enters the superheater and continues to absorb the heat of the flue gas from the top of the furnace, the horizontal flue, and the tail flue through radiation and convection, and makes the superheated steam reach the required working temperature. When a steam boiler is in use, it is impossible to use water vapor for insulation, which leads to waste of water vapor and is not conducive to the energy-saving efficiency of water vapor recycling.

[0022] This embodiment discloses Figures 1 to 4 A steam boiler water supply energy-saving heating equipment shown in the figure includes a boiler body 1, the inner cavity of the boiler body 1 has an upper inner tank and a lower combustion chamber 2, an inlet pipe 3 penetrates the upper part of the peripheral side of the boiler body 1, and a drain pipe 5 penetrates the lower part of the peripheral side of the boiler body 1. The top of the boiler body 1 is penetrated by a U-shaped water vapor circulation component 9 for insulating the upper inner tank of the boiler body 1 with water vapor. The U-shaped water vapor circulation component 9 includes a U-shaped pipe 10 penetrating the inner cavity of the top end of the boiler body 1 and a hollow ring body 13 fixedly connected to one end penetrating to the lower part of the inner tank of the boiler body 1. The U-shaped pipe 10 is connected to the hollow ring body 13, and the top surface of the hollow ring body 13 is provided with a plurality of nozzles 15 in an annular array. When water vapor enters the hollow ring body 13 and is ejected from the four nozzles 15, it can be conducive to the uniform ejection of water vapor, so that the upper inner tank can be evenly heated, and the flow rate of the water vapor can be effectively controlled to be uniform, so that the upper inner tank can be kept warm for a long time.

[0023] The U-shaped pipe 10 is located in the inner cavity of the boiler body 1, and an L-branch pipe 12 is longitudinally penetrated by the bottom side thereof. The U-shaped pipe 10 and the L-branch pipe 12 are each provided with a first valve 14 at one adjacent end. Water vapor enters the L-branch pipe 12, and the upper inner tank can be directly heated by the directly ejected water vapor, thereby accelerating the heat preservation speed of the upper inner tank.

[0024] The U-shaped pipe 10 is wrapped with a rubber insulation sleeve 8 on its circumference. A negative pressure suction fan 11 is provided at one end of the U-shaped pipe 10 close to the boiler body 1. The negative pressure suction fan 11 can suck water vapor in the inner cavity of the boiler body 1 into the U-shaped pipe 10.

After the heating is completed, the combustion in the lower combustion chamber 2 is turned off, and at the same time, the negative pressure suction fan 11 can suck the water vapor in the inner cavity of the boiler body 1 into the U-shaped pipe 10. Through the control of the first valve 14, the water vapor enters the hollow ring body 13, and when it is sprayed out from the four nozzles 15, it can be conducive to the uniform spraying of the water vapor, so that the upper inner tank can be evenly heated. Through the control of the first valve 14, water vapor enters the L branch pipe 12, and the upper inner tank can be directly heated by the directly ejected water vapor, which can speed up the insulation speed of the upper inner tank; when the water in the upper inner tank of the boiler body 1 is discharged, through the control of the second valve 21, when no filtration is required, it is directly discharged from the drain pipe 5, and when filtration is required, it is transported to the filter box 6 through the lower drain pipe 20, filtered through the filter mesh 17 in the filter box 6, and discharged from the filter drain pipe 19 after filtration. At the same time, there is a valve inside the filter drain pipe 19.
