Description

Technical Field

[0001] This utility model relates to the technical field of gas boiler heating, specifically to an energy-saving device for gas boilers. Background Technology

[0002] Existing gas-fired boilers convert the chemical energy of gas into the thermal energy of water, providing a 143°C unsaturated low-pressure steam heat source for air conditioning systems to adjust temperature and humidity. However, heating room-temperature water into steam takes a long time and requires a large supply of gas, which does not meet the production requirements for energy conservation and carbon reduction, resulting in low economic benefits. Utility Model Content

[0003] This utility model proposes an energy-saving device for gas boilers, which can supply water at a certain temperature to the gas boiler through an insulated water tank, thereby reducing the amount of gas used in the heating process and reducing the energy consumption of the gas boiler.

[0006] A further technical solution is that the heating unit is solar-powered.

[0007] A further technical solution is that the heater group includes several parallel heating units, each heating unit includes two parallel water inlet channels on both sides and a solar heating tube connected in the middle of the two water inlet channels on both sides. The number of solar heating tubes is several, and they are arranged in an array perpendicular to the two water inlet channels on both sides.

The number of solar heating tubes is several, and they are arranged in an array perpendicular to the two water inlet channels. The middle of each solar heating tube has a support tube, which is parallel to the water inlet channel and fixedly connected to the several solar heating tubes.

[0009] A further technical solution is that the heating unit includes a main pipe connected to an insulated water tank, and the main pipe is connected to several branch pipes, each of which is connected to a water inlet channel.

[0010] A further technical solution is that the gas boiler contains deionized water.

[0011] A further technical solution is that the water supply pump is a pressure-stabilizing pump.

[0012] The working principle and beneficial effects of this application are as follows:

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-5As shown, an energy-saving device for a gas-fired boiler includes a gas-fired boiler 1, which is connected to an external heating device. The water inlet of the gas-fired boiler 1 is connected to an insulated water tank 3 via a water pump 2. The insulated water tank 3 is connected to a heater group 5 via a circulating pump 4. The heater group 5 is solar-powered.

[0024] In this embodiment, the solar heater group 5 is circulated and connected to the insulated water tank 3. The solar heater group 5 continuously circulates and heats the water in the insulated water tank 3, maintaining a high water temperature. The heated water is stored in the insulated water supply tank and then supplied to the gas boiler 1 via the water supply pump 2. After being heated by the gas boiler 1, the water forms low-pressure 143°C unsaturated low-pressure steam for use by external devices. Compared to heating room temperature water to the required low-pressure steam, the temperature difference between the water in the insulated water tank 3 and the required low-pressure steam is greatly reduced, thereby reducing the working time and intensity of the gas boiler 1, reducing natural gas consumption, and achieving the goal of energy saving and carbon reduction.

[0025] In this implementation, the optimal installation angle for the solar water heater group 5 is generally around 30 degrees. This angle maximizes sunlight exposure and allows the solar water heater's tank to fully absorb solar heat, achieving the best heating effect. Furthermore, the solar water heater should be installed with due south as the reference direction. This maximizes the utilization of solar radiation energy and improves the efficiency of the solar water heater group 5.

[0026] Water at a certain temperature is supplied to the gas boiler 1 through the insulated water tank 3, thereby reducing the amount of gas used in the heating process, reducing the energy consumption of the gas boiler 1, and achieving the purpose of energy saving. The water in the insulated water tank 3 is heated by a solar water heater group, which is environmentally friendly and efficient, and can operate continuously. Even if the water temperature difference caused by seasonal changes in the solar collector will not affect the normal operation of the gas boiler 1.

[0027] like Figure 2 and Figure 4 As shown, an embodiment of a heater group 5 includes several parallel heating units 51. Each heating unit 51 includes two parallel water inlet channels 511 and a solar heating tube 512 connected in the middle of the two water inlet channels 511. The number of solar heating tubes 512 is several, and they are arranged in an array perpendicular to the two water inlet channels 511.

[0028] like Figure 3 and Figure 5As shown, another embodiment of the heater group 5 includes several parallel heating units 51. Each heating unit 51 includes two parallel water inlet channels 511 and a solar heating tube 512 connected in the middle of the two water inlet channels 511. The number of solar heating tubes 512 is several, and they are arranged in an array perpendicular to the two water inlet channels 511. Each solar heating tube 512 has a support tube 513 in the middle. The support tube 513 is parallel to the water inlet channels 511 and is fixedly connected to the several solar heating tubes 512.

[0029] Unlike the above embodiments, the support tube 513 can support several solar heating tubes 512, so that the length of the solar heating tube 512 between every two water inlet channels 511 can be longer, thereby improving the heating efficiency of solar energy and minimizing the number of water inlet channels 511, thus reducing heat loss in the water inlet channels 511.

[0030] When the heating unit 5 is arranged, the main pipe 52 is circulated with the insulated water tank 3. Several branch pipes 53 are connected to the main pipe 52, and each branch pipe 53 is connected to a water inlet channel 511 to ensure the normal circulation of the entire heating unit 5.

[0031] The gas boiler 1 contains deionized water and a pressure-stabilizing pump supplies water to the insulated water tank 3, thus preventing scale buildup in the gas boiler 1 and the heater group 5 due to water quality and other factors.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
