Energy-saving environment-friendly boiler

Abstract

The invention discloses an energy-saving environment-friendly boiler. The energy-saving environment-friendly boiler comprises a feeding hole, a preheating device, a full combustion chamber, a boiler water storage bin, a filter recycler, an exhaust outlet, a water charging pipe and a water discharging pipe; the full combustion chamber is arranged between the boiler water storage bin and the preheating device and is fixedly connected with the filter recycler through a connecting pipe; the filter recycler is arranged between the full combustion chamber and the preheating device; the filter recycler comprises a filter unit layer, a preheating connecting intubation tube and a waste slag collecting cylinder; the exhaust outlet is formed at the top of the filter recycler; and the preheating device is connected between the full combustion chamber and a feeding hole via an L-shaped passage. The energy-saving environment-friendly boiler can be used for preheating a fuel in advance and has the advantages of improving the heating efficiency, achieving an energy saving effect, preventing environmental pollution, increasing the resource utilization rate, realizing collection and utilization of clinkers and preventing waste of resources.

Description

technical field [0001] The invention relates to the technical field of boiler equipment manufacturing, in particular to an energy-saving and environment-friendly boiler. Background technique [0002] With the deepening of my country's reform and opening up and the continuous development of the national economy, the demand for boilers in production and life is also expanding. At present, most of them use hot water and steam boilers. They use water as the heat transfer medium, so the temperature rises slowly and the heat loss is large. The flame stroke in the furnace is short, and the pyrotechnics in the combustion chamber are directly discharged from the flue. Due to the small heat exchange area, a lot of heat is discharged out of the furnace, resulting in energy waste. Due to insufficient combustion of fuel in the furnace, black smoke is emitted from the chimney, which pollutes the environment. Existing hot air boilers have disadvantages to varying degrees, such as high e...
