Device technology configuration method for treating house refuses by using rotary cement kiln

Abstract

The invention provides a device technology configuration method for treating house refuses by using a rotary cement kiln, comprising a pre-treatment device technology configuration method and an incineration device technology configuration method, wherein the whole process of the crushing treatment of the house refuses is implemented by using the pre-treatment device technology configuration method, and a whole incineration process is carried out on the crushed house refuses by using the incineration device technology configuration method; the incineration device technology configuration comprises a double-layer power-driven flap valve, an L-shaped incinerator, a double-layer heavy punch flap valve, a vibrating conveyor and a bucket elevator; and partial tertiary air captured from a tertiary air tube of a rotary kiln enters into the L-shaped incinerator through an air intake tube and high temperature incineration is carried out on the house refuses in the incinerator, smoke generated when incineration passes through an air discharging tube and then is converged with the tertiary air tube, a loop formed by the air intake tube and the air discharging tube of the L-shaped incinerator is provided with a second high-temperature electric butterfly valve and a third high-temperature electric butterfly valve, and a first high-temperature electric butterfly valve is arranged on the tertiary air tube. Harmful gases such as dioxin can be inhibited by high-temperature environment which is generated by using the rotary cement kiln.

Description

[0001] technical field [0002] The invention belongs to the technical field of domestic waste treatment, and in particular relates to an equipment process configuration method for using a cement rotary kiln to process domestic waste. Background technique [0003] With the acceleration of the urbanization process, the output of urban domestic waste in our country continues to increase, which has brought serious harm to the society. According to statistics, the accumulative accumulation of municipal solid waste over the years in my country has reached 6 billion tons, and the annual growth rate of waste production is above 10%. It is estimated that in 2010, the total output of domestic waste in cities above the county level will be about 250 million tons. How to deal with the increasing municipal solid waste has become a major research topic in China today. [0004] The traditional way of disposing of municipal solid waste in China is the landfill method, which is more ...

Problems solved by technology

[0016] In order to solve the above problems, the present invention provides a method of equipment and process configuration using cement rotary kiln to process domestic waste. In particular, the simple pretreatment of domestic waste and the use of L-shaped incinerators for incineration reduce the adverse impact on the output and quality of cement clinker caused by the treatment of urban domestic waste, and the processed domestic waste is fully in line with The goal of 'harmless, reduction, and recycling', domestic waste after treatment can be used as auxiliary materials for cement production
