Problems solved by technology

For example, when some small and medium-sized boilers use low-quality fuel for thermal combustion, the incomplete combustion of the fuel will produce more harmful gases, and the exhaust gas after combustion will convert SO2, SO3 and NO-X carried in the flue gas into condensation. The acid is hidden in the white smoke, and when it accumulates over time, it can form acid rain; and more than 10% of the heat energy is discharged into the atmosphere through the flue gas after combustion, so that the heat in the boiler cannot be used effectively, resulting in energy waste. At the same time, the boiler When boiling water, because the water is not preheated, it takes a long time to boil water, consumes more fuel, and wastes resources

Abstract

The invention discloses an environment-friendly boiler waste heat recovery device for heat recovery based on heat layering, and belongs to the technical field of heat recovery. The environment-friendly boiler waste heat recovery device for heat recovery based on heat layering comprises a base, wherein the top of the base is connected with a slag chamber, the top of the slag chamber is connected with a combustion chamber, a fuel port is formed in the outer wall of the combustion chamber, a chamber door is arranged on the outer wall of the fuel port, ventilation holes which are uniformly distributed are formed in the outer wall of the chamber door, a material turning mechanism is arranged in the combustion chamber, the end, far away from the slag chamber, of the combustion chamber is connected with a heating water tank, a shell sleeves the outer wall of the heating water tank, a first support is connected between the shell and the base, and a smoke outlet used for discharging smoke is formed in the outer wall of the top of the combustion chamber. According to the environment-friendly boiler waste heat recovery device, fuel can be completely combusted, so that harmful gas in the smoke generated after combustion is reduced, and environmental protection is facilitated; and meanwhile, the heat energy of the smoke after combustion is utilized, preheating is carried out before water body heating, so that the fuel consumption is reduced, the water boiling time is shortened, and the resource utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of heat recovery, in particular to an environmental protection boiler residual temperature recovery device for heat recovery based on heat stratification. Background technique [0002] Energy saving and emission reduction is an important theme of today's social development. While using resources and energy more efficiently, it is of great significance to coordinate the green development of the social economy and the environment. Boiler equipment is widely used in various fields of industry, agriculture and daily life.
