Novel without drainage of dioxin production technology for firing brick and tile and making brick and tile using with life garbage in city

Abstract

The invention belongs to the field of circulating economy and environmental protection. The invention particularly relates to a new producing technique of dioxin zero release for using city life rubbish to make brick and tile by fire. At first, the rubbish is processed to dry status while selecting plastic and copper or iron made impurities; then the rubbish is thrown into brick and tile kiln to be fully burnt and later is used as regenerated resource for making bricks and tiles by fire. The rubbish burnt residues are used for making the bricks and tiles. During the burning process of the rubbish, the original residual toxic articles caused by burning the rubbish are eliminated by utilizing the unique structure of the kiln; in addition, the flying dust and toxic articles are fully burnt. The fume is decomposed by strong oxygenation and is burnt into oxycarbide without remnant for a long time and for many times when in running process, and the zero release of dioxin is achieved. The fume is purified by three layers of facilities inside a high chimney, and thus the normal temperature vapor released from the high chimney has zero release.

Description

technical field [0001] The invention relates to a new technology for producing bricks and tiles with urban domestic garbage and incineration slag for zero-emission of dioxins. It turns waste into treasure, saves energy, and belongs to the comprehensive utilization of resources. The garbage treatment is harmless and reduces the amount of waste. Economics, recycling, and environmental protection, and also in the field of circular economy and waste utilization in the production of building materials. Background technique [0002] The disposal of municipal solid waste (abbreviated as garbage herein) is a worldwide problem. [0003] People produce a lot of garbage in their daily life, which plagues the development of cities and brings heavy burdens and disasters to cities. Governments have to spend a lot of manpower, material and financial resources to explore and study the disposal of garbage. [0004] There are billions of tons of garbage in our country, and at the same time,...

AI Technical Summary

Problems solved by technology

Only after incineration, the incineration slag is used to make bricks and tiles. First, there is an exact ratio of the amount of slag mixed. Second, the bricks and tiles are made smoothly and the product quality is guaranteed. As for the production cost, it will definitely be high. At that time, the ideas and policies were not in place. Technology has not kept up and cannot be solved yet
