Description

Technical Field

[0001] The present invention relates to the technical field of boiler equipment, and in particular to a high-efficiency heating boiler and a use method thereof. Background Art

[0002] Boilers are common heating equipment that heats liquids. In the process of heating liquids, a heat source is required to heat the liquid. Generally, the heat source is generated by burning fuel, such as natural gas, and the container containing the liquid is heated to achieve the purpose of heating.

[0003] When existing natural gas boilers heat containers containing liquid, the flame can only directly heat the outer part of the container near the flame, and the liquid inside the container is heated slowly and takes a long time. The flue gas generated by the combustion of natural gas in existing natural gas boilers is directly discharged, which not only wastes a large amount of heat contained in it, but also the particulate pollutants contained in the flue gas will pollute the environment.

[0004] The existing patent (application number: CN202020699276.4) proposes a heating structure of a high-efficiency natural gas heating boiler, including a preheating chamber, a heat-conducting filter chamber and a heating chamber, wherein an annular column is provided inside the heating chamber, a fan is installed at the bottom of the heating chamber, the heating chamber and the heat-conducting filter chamber are connected through an exhaust pipe, a heat-conducting column is installed inside the heat-conducting filter chamber, the top of the heat-conducting column extends into the preheating chamber, an activated carbon filter is provided at the bottom of the heat-conducting column, a water pump is connected to the top side of the preheating chamber, and a water pump is installed at the other end of the water pump, and the other end of the water pump is connected to a water inlet main pipe, the water inlet main pipe is divided into a water inlet branch pipe, the contact area between the liquid and the flame is increased, the liquid heating speed is accelerated, and the work efficiency is improved; the liquid can be preheated, the subsequent heating time is reduced, the work efficiency is further improved, and the waste of heat energy can be avoided, and the pollutants in the smoke can be avoided from polluting the environment.

[0005] However, the above-mentioned boiler has certain shortcomings during use. During use, the magnesium ions and calcium ions contained in the boiler water are easily combined with acid ions to produce precipitation during the heating process. After a certain period of use, these precipitates adhere to the inner wall of the boiler and form scale, resulting in poor heating effect, affecting the heat transfer efficiency and reducing the heating efficiency of the boiler.

8. The high-efficiency heating boiler according to claim 4, characterized in that: The connecting pipe (19) is a retractable hose structure, the connecting pipe (19) is made of stainless steel, and the outer surface of the connecting pipe (19) is coated with a Teflon coating.

9. The method for using a highly efficient heating boiler according to claims 1-8, characterized in that: The following steps are involved: S1. External water is injected into the interior of the electric heating furnace body (1) through the water inlet pipe (28), and then the electric control panel (26) controls the electric heating furnace body (1) to electrically heat the water inside. S2, starting the driving motor (4), driving the driving gear (5) to rotate through the driving motor (4), and the driving gear (5) drives the upper turntable (2) to rotate through the teeth (6) meshing with the upper turntable (2), and the upper turntable (2) drives the reciprocating screw rod (7) and the cleaning ring (8) to rotate inside the electric heating furnace body (1), and the cleaning brush (10) provided on the cleaning ring (8) can be used to perform a rotating scraping and cleaning of the inner wall of the electric heating furnace body (1), thereby preventing scale generated by the heated water from adhering to the inner wall of the electric heating furnace body (1), preventing the scale from reducing the heat transfer efficiency, achieving uniform heat transfer, improving the heat transfer efficiency, and at the same time improving the safety of the use of the electric heating furnace body (1). S3. During the rotation of the upper turntable (2), the transmission gear (11) provided on the reciprocating screw (7) will roll and mesh with the gear ring (12) provided on the inner wall of the electric heating furnace body (1), thereby causing the reciprocating screw (7) to rotate on the upper turntable (2). During the rotation of the reciprocating screw (7), the cleaning ring (8) threadedly connected thereto can be driven to reciprocate up and down, thereby increasing the cleaning range of the inner wall of the electric heating furnace body (1) and making the cleaning more comprehensive. S4. During the process of the cleaning ring (8) moving up and down, the follower gear (15) installed thereon will roll and mesh with the fixed rack (16) installed between the upper turntable (2) and the lower turntable (3), thereby causing the follower gear (15) to rotate on the cleaning ring (8). When the follower gear (15) rotates, it can drive the annular shaft (13) and the cleaning brush (10) to rotate on the cleaning ring (8). The cleaning brush (10) in the rotating state cleans the inner wall of the electric heating furnace body (1), which can effectively improve the cleaning efficiency. S5. During the cleaning process, the air pump (23) drives the air delivery pipe (25) to extract the hot air generated by the water heating inside the electric heating furnace body (1). The hot air will be transported to the inside of the air intake chamber through the air extraction pipe (24). The hot air in the air intake chamber will be transported to the inside of the support rod (20) through the connecting pipe (19) and then sprayed out from the water spray hole (22). The sprayed hot air will cause bubbles to be generated in the water inside the electric heating furnace body (1). The bubbles will flow near the inner wall of the electric heating furnace body (1), which can force the water flow rate near the inner wall of the electric heating furnace body (1) to increase. The high-speed water flow can flush the inner wall of the electric heating furnace body (1), making it difficult for the inner wall of the electric heating furnace body (1) to be scaled. At the same time, due to the accelerated water flow rate, the heat exchange efficiency can be improved. S6. Due to the principle that hot water floats, the heated water will gather at the upper part of the electric heating furnace body (1), and the heated water will be discharged through the water outlet pipe (27) for use.
