Embodiment

[0043] In the optional scheme of this embodiment, such as figure 1 As shown, a kind of compound furnace kiln provided in this embodiment comprises a forehearth 100 and a tunnel kiln 200; It is used for firing finished bricks with humus as raw material; the tunnel kiln 200 includes a preheating section 210 , a calcination section 220 and a cooling section 230 connected in sequence; the forehearth 100 communicates with the calcination section 220 .

[0044] In this embodiment, the setting of the forehearth 100 ensures the effective combustion of the RDF fuel made of mineralized waste light combustibles, and the concentrated leachate is sprayed and burnt through the forehearth 100 to provide the refractory leachate The heat generated by fuel combustion in the forehearth 100 is directly introduced into the tunnel kiln 200 as supplementary heat for brick calcination. The combination of the tunnel kiln 200 and the forehearth 100 ensures that the heat generated by fuel combustion can...

Abstract

The invention discloses a composite kiln. The composite kiln comprises a front furnace and a tunnel kiln. The front furnace is used for incinerating combustible matters and percolate in mineralizationgarbage and feeding heat to the tunnel kiln; the tunnel kiln is used for burning finished bricks with humus as raw materials; the tunnel kiln comprises a preheating section, a calcining section and acooling section communicating in sequence; and the front furnace communicates with the calcining section. In the composite kiln, the tunnel kiln calcines adobes with the humus as main raw materials;the humus are prepared as the finished bricks; the front furnace incinerates the screened combustible matters; a heat source is provided for calcining of the adobes by the tunnel kiln; and meanwhile,the front furnace incinerates the percolate, so that the percolate treatment process flow is simplified, and whole conversion of products after screening of stale garbage is realized.

Description

technical field [0001] The invention relates to the technical field of stale garbage treatment, in particular to a composite furnace. Background technique [0002] Garbage management is a common problem faced by all countries in the world. With the rapid development of industries in various countries, more and more cities with a large population concentration, and the continuous improvement of human living standards, there are more and more garbage on the earth. [0003] During the process of transportation, storage and treatment of municipal solid waste, there is the possibility of secondary pollution, which will pollute the atmosphere, soil and water. It not only affects the quality of urban environment, but also threatens the health of residents, becoming one of social hazards. [0004] At present, human beings are not only faced with the problem of new garbage, but also the stale garbage accumulated for many years has also become a public hazard to society. [0005] A...
