Description

Technical Field

[0001] This utility model belongs to the field of gas boiler technology, specifically relating to an energy-saving gas boiler. Background Technology

[0002] A gas-fired boiler is a high-efficiency thermal energy device that uses natural gas, liquefied petroleum gas, or other fuels. It heats water or produces steam through combustion and is widely used in heating and industrial production. Its advantages include quick start-up, easy operation, good environmental performance, and high energy efficiency.

[0003] Existing gas-fired boilers typically have a chamber at the top of the combustion chamber through which the water to be heated flows. However, the water spends a short time in this chamber, resulting in low heating efficiency. Furthermore, the flue gas containing heat from combustion is directly emitted, further hindering fuel utilization. Therefore, a new type of energy-efficient gas-fired boiler is needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses an energy-saving gas-fired boiler.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An energy-saving gas-fired boiler includes a vortex-shaped water tank, with side water tanks fixedly connected to both sides of the vortex-shaped water tank. The inner end pipe of the vortex-shaped water tank is simultaneously connected to the central hole of both side water tanks. The vortex-shaped water tank and the two side water tanks together form a vortex-shaped flue. A gas burner is inserted into the center of the vortex-shaped water tank, and an air conveyor is provided below the gas burner. The edge holes of the two side water tanks are connected to a water outlet pipe, and the outer end pipe of the vortex-shaped water tank is connected to a water inlet pipe.

[0007] As a preferred embodiment of this utility model, a fixing plate is embedded in the center of one of the side water tanks, and the delivery pipes of the gas burner and the air conveyor pass through the fixing plate.

[0008] As a preferred embodiment of this utility model, the portions of the gas burner and air conveyor that extend into the center of the vortex-shaped water tank are arc-shaped, with the outer side of the arc facing upwards, and the arc-shaped portions of the gas burner and air conveyor are coaxial.

[0009] As a preferred technical solution of this utility model, both the gas burner and the air conveyor are provided with a number of thin tubes that are parallel to and uniformly distributed with respect to the axis of their own arc-shaped portion, and each thin tube is provided with a number of linearly uniformly distributed thin holes facing outward from the arc-shaped portion. Each thin tube of the air conveyor is provided between adjacent thin tubes of the air conveyor.

[0010] As a preferred embodiment of this utility model, the inner cavity of the side water tank is provided with a vortex-shaped baffle, and the vortex-shaped baffle divides the inner cavity of the side water tank into a vortex-shaped water channel, and the central hole and the edge hole are respectively provided at both ends of the vortex-shaped water channel.

[0011] As a preferred embodiment of this utility model, the bottom of the vortex-shaped water tank is fixedly connected to a base.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this application, the heated water flows in the vortex water channel of the vortex water tank and the side water tank. During the flow, the heating time and heating area are extended as much as possible, thereby improving the heating efficiency. At the same time, the flame and flue gas in the vortex flue can heat the water. The water can be heated by the flue gas as soon as it flows into the vortex water tank, thereby improving the fuel utilization rate.

[0014] Second, in this application, the air ejected from the fine tubes and orifices of the air conveyor directly passes through the through groove between adjacent fine tubes of the air conveyor, so that the gas is fully combusted. At the same time, the flame and flue gas of the gas combustion are blown into the vortex flue and extended, which improves the combustion efficiency and increases the distribution of the high-temperature heating area of ​​the gas boiler.

[0025] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0026] Please see Figure 1-6 An energy-saving gas-fired boiler includes a vortex-shaped water tank 1, with side water tanks 2 fixedly connected to both sides of the vortex-shaped water tank 1. The inner end pipe 101 of the vortex-shaped water tank 1 is simultaneously connected to the central hole 201 of both side water tanks 2, and the vortex-shaped water tank 1 and the two side water tanks 2 together form a vortex-shaped flue. A gas burner 4 is inserted into the center of the vortex-shaped water tank 1, and an air conveyor 5 is located below the gas burner 4. An ignition device (shown in the attached drawing) fitted to the fine hole of the gas burner 4 is also located in the center of the vortex-shaped water tank 1. The edge holes 202 of the two side water tanks 2 are connected to an outlet pipe 6, and the outer end pipe 102 of the vortex-shaped water tank 1 is connected to an inlet pipe 7. Both the outlet pipe 6 and the inlet pipe 7 are equipped with flanges for connecting to external pipelines.

[0027] One of the side water tanks 2 has a fixed plate 3 embedded in its center, and the delivery pipes of the gas burner 4 and the air conveyor 5 pass through the fixed plate 3. The delivery pipes of the gas burner 4 and the air conveyor 5 are both equipped with flanges for connecting to external pipelines, and the delivery pipes of the gas burner 4 and the air conveyor 5 are respectively connected to the gas pipeline and the blower pipeline.

[0028] The portions of the gas burner 4 and air conveyor 5 extending into the center of the vortex-shaped water tank 1 are arc-shaped, with the outer side of the arc facing upwards. The arc-shaped portions of the gas burner 4 and air conveyor 5 are coaxial. Both the gas burner 4 and air conveyor 5 are provided with several thin tubes that are parallel to and evenly distributed along the axis of their own arc-shaped portions, and each thin tube has several linearly evenly distributed fine holes facing outwards from the arc-shaped portion. Each thin tube of the air conveyor 5 is positioned between adjacent thin tubes of the air conveyor 5, and the air ejected from each fine hole of the air conveyor 5 passes directly through the through-slot between adjacent thin tubes of the air conveyor 5.

[0029] The inner cavity of the side water tank 2 is provided with a vortex-shaped baffle, which divides the inner cavity of the side water tank 2 into a vortex-shaped water-blocking channel. The central hole 201 and the edge hole 202 are respectively located at both ends of the vortex-shaped water-blocking channel. The water flowing into the side water tank 2 from the inner end pipe 101 of the vortex-shaped water tank 1 flows from the center of the side water tank 2 to the edge of the side water tank 2 along the vortex-shaped water-blocking channel.

[0030] A base 8 is fixedly connected to the bottom of the vortex-shaped water tank 1. The base 8 is fixedly connected to the bottom of the vortex-shaped water tank 1 by at least two round rods, and the bottom plate of the base 8 is provided with at least two fixing through holes.

[0031] Working principle:

[0032] During operation, the gas burner 4 and the air conveyor 5 convey the gas and air respectively through their conveying pipes. Then, the gas is ejected from the fine hole of the gas burner 4 and the air is ejected from the fine hole of the air conveyor 5. Then, the ignition device ignites the gas ejected from the fine hole of the gas burner 4, and the air ejected from the fine hole of the air conveyor 5 provides the oxidant. Since the air ejected from the fine hole of the air conveyor 5 directly passes through the through groove between the adjacent fine pipes of the air conveyor 5, the gas is fully combusted. At the same time, the flame and flue gas of the gas combustion are blown into the vortex flue by the blown air and extend.

[0033] While the gas is burning, the inlet pipe 7 inputs cold water into the outer end pipe 102 of the vortex water tank 1. When the cold water flows from the outer end pipe 102 to the inner end pipe 101, it is heated by the flame and flue gas in the vortex flue. Then the heated hot water flows into the two side water tanks 2 respectively. When the hot water flows in the vortex water channel of the side water tank 2, it continues to be heated by the flame and flue gas in the vortex flue. Finally, the hot water flows out from the outlet pipe 6.

[0034] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
