Oxygenating device and oxygenating method for increasing waste treatment capacity of rotary kiln

Abstract

The invention provides an oxygenating device for increasing the waste treatment capacity of a rotary kiln. The device comprises a decomposition furnace, the rotary kiln, a tertiary air duct for connecting the head of the rotary kiln with the decomposition furnace, and a miniature rotary kiln arranged in parallel with the tertiary air duct, one end of the miniature rotary kiln is communicated withthe tertiary air duct through a first pipeline, the other end is communicated with the decomposition furnace through a second pipeline, and the first pipeline and / or the second pipeline are / is provided with an oxygen injection inlet; and the first pipeline, communicated with the tertiary air duct of the miniature rotary kiln is provided with a waste filling port. The device realizes the harmless treatment process of solid wastes while producing a cement clinker, improves the filling amount of the wastes, prolongs the heat exchange time, increases the treatment efficiency of the wastes, and canensure the total oxygen content of tertiary hot air of the decomposition furnace.

Description

technical field [0001] The invention relates to the technical field of cement production cooperative waste treatment, in particular to an oxygen supplement device and an oxygen supplement method for increasing the waste disposal capacity of a rotary kiln. Background technique [0002] With the continuous development of social science and technology, the problem of continuous pollution of the environment has also emerged. The environment on which human beings live is very fragile. In order to protect the environment, people have adopted restrictions on the discharge of pollutants. At the same time, people are also making continuous efforts to deal with pollutants. [0003] The kiln for cement production has a high temperature and strong oxidative alkaline environment during the high temperature calcination of clinker in the rotary kiln. The high temperature and strong oxidative alkaline environment provides excellent treatment conditions for some solid waste that meets the re...

AI Technical Summary

Problems solved by technology

[0004] For example, when waste is sprayed from the kiln head or waste is added to the calciner, there may be excessive heat absorption or excessive heat release in the kiln head or calciner, resulting in a limited amount of waste disposal

Moreover, when an accident occurs during the waste disposal process, the cement kiln needs to be closed for inspection and maintenance, which will affect the operation of the cement kiln
