Problems solved by technology
[0002] Disposal of garbage is a serious problem faced by the process of urbanization and economic development. In the existing technology, the incineration of garbage in garbage stations is not complete, and it cannot adapt to the incineration of garbage with high moisture and low calorific value in China. The incineration of garbage is not complete. Emissions have a certain impact on the surrounding environment

Embodiment Construction
[0017] With reference to the accompanying drawings, the specific implementation of the present invention will be further described in detail through the description of the embodiments.
[0018] The waste incineration secondary air duct system of the present invention, such as figure 1 , 3 As shown, the incinerator 10 is included. The incinerator 10 is provided with a grate 4, and an air inlet chamber 5 is provided under the grate 4. The secondary air blower 9 extracts the secondary air from the front and rear sides of the furnace of the incinerator 10. Two channels are divided into the furnace 6 on the front and rear sides. Such as image 3 As shown in the schematic diagram of the secondary air passage, the secondary air enters from the front and rear sides of the furnace wall and then divides into two air ducts. This structure can increase turbulence, stir the flue gas, and strengthen the disturbance of the gas in the furnace 6 to ensure The full mixing of fuel gas effectively ...

The invention discloses a waste incineration secondary air duct system. The waste incineration secondary air duct system comprises an incinerator, and fire grates are arranged inside the incinerator; air inlet chambers are arranged under the fire grates; a secondary air fan sends extracted secondary air from the front and back sides of a hearth of the incinerator; and secondary air enters the hearth from two channels on the front and back sides. According to the waste incineration secondary air duct system, secondary air enters a reburning zone in a secondary air duct form, after entering from the front and back sides of the incinerator wall, secondary air is divided to flow through two air ducts, turbulence can be increased through the structure, flue gas is stirred, disturbance of air in the hearth is strengthened, sufficient mixing of gas is guaranteed, unburned volatiles are effectively eliminated, the combustion ratio can be greatly increased, complete waste incineration is guaranteed, and the system is energy-saving and environment-friendly and has relatively good application prospects.
Description
Technical field [0001] The invention belongs to the technical field of waste treatment, and more specifically, relates to a secondary air duct system for waste incineration. Background technique [0002] The treatment of garbage is a serious problem faced by the process of urbanization and economic development. In the prior art, the garbage station is not completely burned in the garbage incinerator, and cannot adapt to the domestic high-moisture, low-calorie garbage incineration, and the incomplete garbage incineration. Emissions have a certain impact on the surrounding environment. Summary of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, provide a method that ensures the full mixing of gas, effectively eliminates unburned volatiles, can greatly increase the combustion rate, ensure complete incineration of garbage, and energy-saving and environmentally-friendly garbage incineration twice Air duct system. [0004] I...
