Energy-saving emission-free and non-pressure hot water boiler

Abstract

The invention discloses an energy-saving emission-free and non-pressure hot water boiler comprising a boiler body, a drive shaft, and a drive motor. The drive shaft is inserted in the axial center of the boiler body. The wall of the boiler body is provided with a water inlet and a water outlet. The drive shaft is fixedly connected with the boiler body through a bearing; and the outer end of the drive shaft is driven by the drive motor. An inner heating element, an outer heating element and a flow guidance impeller are arranged inside the boiler body. The drive shaft is provided with the flow guidance impeller and the inner heating element, and the outer heating element is installed on the inner wall of the boiler body corresponding to the outer end of the inner heating element. The end face of the inner heating element presses against the end face of the outer heating element, so as to convert a cold water which enters the boiler body from the water inlet into a hot water through the heat generated by a mutual friction between the inner heating element and the outer heating element; and the hot water is discharged from the water outlet of the boiler body. Being environment-friendly and pollution-free, and being energy-saving, the energy-saving emission-free and non-pressure hot water boiler has the advantages of novel structure, high conversion efficiency, high safety, convenient maintenance, small space occupation, low machining cost, or the like.

Description

technical field [0001] The invention relates to the technical field of water heating equipment, in particular to an energy-saving non-drainage and pressureless hot water boiler. Background technique [0002] As we all know, existing heating devices usually use coal-fired heating, oil-fired heating, and electric heating. The pollution is even more serious. These two heating methods not only produce smoke and harmful gases such as carbon monoxide, sulfur dioxide and nitrogen hydride, but also consume a large amount of natural energy such as coal or oil, which does not comply with the national energy conservation and emission reduction policies. [0003] In order to solve the substantive technical problem of wasting natural resources, an invention patent with the publication number CN103591420 and the invention title of "heating device that converts mechanical energy into heat energy" has been published on the Internet. The utility model patent of the hot water boiler uses the...

Problems solved by technology

[0002] As we all know, the existing heating devices usually use coal-fired heating, oil-fired heating, and electric heating. The disadvantages of coal-fired and oil-fired heating are: Both will cause environmental pollution, especially coal-fired heating is more serious to the environment. These two heating methods not only produce smoke, harmful gases such as carbon monoxide, sulfur dioxide and nitrogen hydride, but also consume a large amount of coal or oil. and other natural energy, which does not comply with the national energy conservation and emission reduction policies

[0003] In order to solve the substantive technical problem of wasting natural resources, a kind of publication number CN103591420 has been disclosed on the Internet, and the title of the invention is "heating device for converting mechanical energy into thermal energy" "Invention patent, publication number CN2037771661, invention name is a utility model patent for a hot water boiler without combustible fuel, which uses the pump shaft to drive the flywheel in the pump body to rotate, and the liquid generates centrifugal force under the high-speed rotation of the flywheel, making the liquid quickly It enters the liquid storage cavity, and is gradually thrown to the liquid outlet through the gap between the pump teeth and the pump tooth slots and the gear teeth and the gear slots. At the same time, during the liquid throwing process, the liquid passes through the friction between the flywheel and the pump body. When damping the channel, the high-speed collision between the liquid molecules will make the liquid gradually heat up, so that the mechanical energy between the flywheel and the pump body will cause friction between the liquid molecules and convert it into heat energy that makes the liquid heat up. The liquid in the pump body can be adjusted according to the needs The temperature of the hot water is circulated to raise the temperature. After testing, the maximum temperature of the heat energy of the liquid discharged after multiple cycles can reach 100 degrees Celsius, which meets a variety of working environments that require hot water. In addition to no environmental pollution, its heat conversion efficiency is higher than that of The conversion of coal boilers and electric boilers is high, and its substantial shortcomings are: first, because the water temperature is caused by the high-speed collision between liquid molecules and liquid molecules, the liquid gradually heats up, resulting in long heating time; second, the motor shaft load is large, and the use of motor power High power consumption, and the cost of use is higher than that of coal and electricity; third, when processing the workpieces of the pump body and flywheel, the machining accuracy is very high, and the mold manufacturing cost of the pump body and the wheel body is high
