Problems solved by technology

[0004] At present, the countercurrent rotary kiln mainly generates negative pressure through the induced draft fan, and sucks the primary air and the secondary air respectively from the gap between the slag outlet, the rotary kiln and the secondary combustion chamber. The main problems are: (1) only the air can be sucked from the atmosphere
(2) The total air intake of primary air and secondary air can only be adjusted through negative pressure, and there is no way to adjust the air distribution ratio of primary air and secondary air

Abstract

The invention provides a rotary kiln for garbage incineration. The rotary kiln comprises a primary air system and a secondary air system. The primary air system comprises a primary air frequency conversion fan which communicates with a storage pit and is used for introducing odors in the storage pit into the rotary kiln to serve as primary air. The secondary air system comprises a secondary air frequency conversion fan which communicates with the storage pit and is used for introducing the odors in the storage pit into the rotary kiln to serve as secondary air. The odors in the storage pit areintroduced to serve as the primary air and the secondary air, and thus the pressure of a deodorization system can be reduced; and meanwhile, the primary air system and the secondary air system are both provided with the frequency conversion fans, real-time monitoring can be conducted, and according to different materials, the air inlet quantity of the primary air and the secondary air can be automatically adjusted, so that automatic control of an incineration system is achieved.

Description

technical field [0001] The invention relates to the field of industrial waste treatment, in particular to a rotary kiln for waste incineration. Background technique [0002] With the rapid development of various industries, it has brought rapid growth to the economy. However, the treatment of various industrial wastes is still dominated by extensive landfills in my country. However, with the shortage of land resources and environmental protection issues, now The country is actively promoting other treatment methods, and incineration is currently the most effective harmless and reduced waste treatment method. [0003] Rotary kiln is a type of furnace that is widely used in hazardous waste incineration, and it can be applied to various types of medical waste and combustible industrial hazardous waste. Among them, the countercurrent rotary kiln has gradually become an important type of furnace for hazardous waste incineration in China due to its low slag discharge temperature, ...
