Energy-saving efficient environment-friendly air returning boiler

Abstract

The invention discloses an energy-saving efficient environment-friendly air returning boiler which comprises a boiler body and a waste heat recycle and desulfuration device. The boiler body comprises a boiler shell and a smoke pipe, a boiler main body is arranged in the boiler shell, a hearth and a boiler ash chamber are arranged in the boiler main body, a filler opening is formed in the hearth, a boiler ash opening is arranged on the boiler ash chamber, a fire grate is arranged between the hearth and the boiler ash chamber, a cavity is formed between the boiler shell and the boiler main body, and a boiler cover is arranged on the top of the boiler shell and is higher than the boiler main body. The boiler is simple and reasonable in structure, integrates cooking, heating and baking, and is convenient to use. The cavity is formed between the boiler shell and the boiler main body, and a hot water pipe is arranged on the outer side of the boiler main body so that the hot water pipe can be heated through the hearth, and generated smoke flows upwards and flows out from the smoke pipe through the cavity. Meanwhile, the hot water pipe can be heated for the second time through the smoke. A spiral water pipe is further arranged on the hearth, so that heat and smoke waste heat of the hearth are effectively used, and the heat utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of boiler equipment, in particular to an energy-saving, high-efficiency and environment-friendly return air furnace. Background technique [0002] At present, for the stoves used in most of our families, the temperature around the stove rises from bottom to top after the fire is fired, and part of the heat generated by the fuel is discharged through the exhaust port. The exhaust port is generally arranged on the upper part of the furnace body, which prevents the heat generated by the fuel from being fully utilized. Moreover, during the fuel combustion process, the temperature of the furnace body and the furnace surface increases greatly, but the temperature increase of the entire furnace base is not obvious. In addition, during the use of the boiler, due to incomplete combustion, the exhaust gas usually contains various gaseous pollutants that affect the air quality, among which the sulfur dioxide flue gas ...

AI Technical Summary

Problems solved by technology

This is currently the problem of energy waste and environmental pollution during the use of boilers. We need to develop a technology to recover and utilize the heat energy lost by boiler tail gas; and while recovering heat, adopt desulfurization technology to absorb boiler Sulfur dioxide exhaust gas discharged from the air, reducing pollution emissions, achieving the goals of energy saving, environmental protection, and cost saving
