Embodiment 1

[0027] Embodiment one: A domestic waste pyrolysis gasification combustible gas is used in the shale sintered brick process, such as figure 1 As shown, it includes the following steps: 1) The domestic waste is processed by the heat source combined drying process, and the processed material is sent to the RDF rod making machine to make RDF solid fuel (for details about the heat source combined drying process, see another article named Patent application for "a domestic waste heat source combined drying process"); 2) Send RDF solid fuel into the pyrolysis gasifier for pyrolysis and gasification to obtain combustible gas; 3) Send the combustible gas into the brick sintering kiln, Burn finished bricks; while disposing of domestic waste, use the heat generated by the waste to burn bricks to achieve the purpose of comprehensive utilization of resources, reduce environmental pollution, reduce brick-making costs, and increase economic benefits; 4) For bricks that have completed step 3...

Embodiment 2

[0028] Embodiment two: A domestic waste pyrolysis gasification combustible gas is used in the shale sintered brick process, such as figure 2 As shown, it includes the following steps: 1) The domestic waste is subjected to heat source combined drying process; 2) The domestic waste treated in step 1) is directly sent to the pyrolysis gasifier for pyrolysis and gasification to obtain combustible Gas; 3) Send combustible gas into the brick-making sintering kiln, burn the finished bricks, and discharge waste heat gas; 4) Ventilate and cool the finished bricks in the brick-making sintering kiln after completing step 3), and extract the heat generated by cooling; 5) Send the combustible gas into the brick kiln for combustion in step 3) and combine the exhausted waste heat gas with the hot gas generated by cooling in step 4); 6) combine part of the gas after step 5) Pass into the drying kiln of the brick factory to dry the bricks; the other part passes into the drying drum used in ...

Abstract

The invention discloses application of household refuse pyrolytic gasification combustible gas in shale sintered brick process, including the steps of treating household refuse with combined heat drying process to produce RDF (refuse derived fuel), and performing pyrolytic gasification to obtain combustible gas; delivering the combustible gas into a brick-producing sintering kiln to sinter finished bricks; exhausting waste heat gas produced by cooling of finished bricks; mixing waste heat gas produced by combustion in the brick-producing sintering kiln and hot gas produced by cooling; introducing part of mixed gas into a brickyard drying kiln to dry green bodies; introducing the other part into a drying cylinder that is used in the drying process to dry refuse; introducing gas that is produced by drying the refuse into a brickyard blower and a pyrolytic gasifier blower. Heat produced by the refuse is utilized to sinter bricks during domestic refuse treatment, so that heat is made full use; stinking gas produced by drying the refuse is introduced into the brickyard blower and the pyrolytic gasifier blower and is combusted, thereby being discharged.

Description

technical field [0001] The invention relates to the technical field of recycling of household garbage, in particular to a process of using domestic garbage pyrolysis gasification combustible gas for shale sintered bricks. Background technique [0002] With the improvement of people's living standards, the output of domestic waste is constantly increasing, and the composition of domestic waste is becoming more and more complex, seriously polluting the environment and affecting people's health. The traditional domestic waste treatment method is to directly landfill the waste, which not only affects the soil but also pollutes water sources. After a long period of research, those skilled in the art have explored a method of pyrolyzing and gasifying domestic waste at high temperature to obtain combustible gas and residual slag, thereby turning domestic waste into a usable energy source and converting the remaining slag Landfilling can greatly reduce the pollution to the environm...
