Abstract

The invention discloses a secondary combustion chamber for household garbage flue gas. The secondary combustion chamber includes a heat insulation sealing cover flange, a preheating cone cover, a heatinsulation sealing cover, a fire-resistant insulating material, a secondary combustion chamber cavity, an outer shell, a furnace door, furnace legs, a 360-degree air inlet grill, an ash remover, a slag remover, a flue gas holding flue and a porous high-temperature heat storage body; the furnace legs are fixedly arranged at the bottom of the outer shell, the lower ends of the furnace legs are fixedly connected with an embedding connection board, the fire-resistant insulating material is arranged on the top side of the outer shell, the furnace door is formed in one side of the bottom of the outer shell, the secondary combustion chamber cavity is formed in the inner side of the outer shell, and a venturi throat structure is arranged at a flue gas outlet of the secondary combustion chamber cavity. The secondary combustion chamber ensures that the temperature of flue gas entering the second combustion chamber is stabilized at the ignition point temperature, combustion is more stable, and therefore external adding of a combustion booster is not required during combustion in the second combustion chamber; and meanwhile, dust removing is facilitated, and flue blocking is not prone to happening.

Description

technical field [0001] The invention relates to the technical field, in particular to a secondary combustion chamber for flue gas of domestic garbage. Background technique [0002] The secondary combustion chamber is a device for secondary combustion pyrolysis of harmful gases and high-temperature incineration of tar in the field of garbage and sludge incineration and pyrolysis. Hazardous components, especially dioxin-like hazardous substances, secondary combustion is an indispensable condition. At present, most of the working conditions of secondary combustion of flue gas need to add a burner, or the residence time is not enough. The secondary combustion technology still needs to be solved. Improved optimization. [0003] In the prior art, when the incomplete combustion of carbon monoxide, carbon black, dust, tar and other combustible attachments in the first combustion chamber enter the second combustion chamber, when the temperature of the flue gas rises to a certain val...
