What the present invention proposed is the method for the building materials production of building materials field, and specifically the application of city life garbage baking lightweight aggregate reaches the method for producing materials for wall with it.
Background technology
The patent No. that is proposed by Siemens Company is to disclose the rubbish heat-treating methods in 921097409 " method and apparatus of hot disposal of garbage ", the content of its specification digest is: the equipment of hot disposal of garbage comprises the low-temperature pyrolysis reactor (2) and a combustion chamber (8) of low-temperature pyrolysis gas and low-temperature pyrolysis resistates, is used for incendiary low-temperature pyrolysis coal gas to this combustion chamber supply.The less low-temperature pyrolysis material output combustion chamber (8) of separating in salvage stores tripping device (20) is burnt at there low-temperature pyrolysis gas.Rubbish/the liquid refuse that can directly carry the dirt shape to combustion chamber (8).Also can import additional fuel.Combustion chamber (8) is provided with discharge device (35), can take out slag fused from discharge device.Slag for example in the pond, becomes the vitrifying shape after cooling.Flue gas is discharged through flue gas pipeline (10).The present invention is suitable for handling all kinds of rubbish.
Principal claim is: the equipment that is used for hot disposal of garbage has the low-temperature pyrolysis reactor (2) that rubbish is transformed into low-temperature pyrolysis gas and the remaining solid material of low-temperature pyrolysis, the discharge device (3) that is used for the remaining solid material of low-temperature pyrolysis that is connected with low-temperature pyrolysis reactor (2), with low-temperature pyrolysis gas exhaust pipe (4) with discharge low-temperature pyrolysis gas and little dust, an and combustion chamber (8), low-temperature pyrolysis gas and little dust are supplied with this combustion chamber, it is characterized in that
--can import extraordinary rubbish to low-temperature pyrolysis reactor (2),
--settled a resistates tripping device (3,20) to be used for the low-temperature pyrolysis resistates is divided into thick component and thin component in low-temperature pyrolysis resistates one side of discharge device (3),
--be used for the combustion chamber (such as 8) of small component pipeline (21) oxygen-enriched combusting of thin component,
--can be directly the dirt shape, exsiccant rubbish and/or liquid refuse by the road (32,33) flow to combustion chamber (for example 8),
--(34) additional fuel feed combustion chamber (for example 8) by the road,
--combustion chamber (such as 8) keep the sufficiently long time gas that fuel produced by input on a certain temperature, thereby produce molten slag,
--combustion chamber (such as 8) are provided with discharge device (35), can take out slag fused from this device, become the vitrifying shape after slag fused is cooled;
--and have a flue gas pipeline (10) from the combustion chamber (for example 8) lead to (14).
Say compactly according to its technology contents analysis: with solid, liquid refuse joins in the dry distiller, the heating combustible gas that destructive distillation produced is used for rubbish fused thermal source, thin component of last resistates and the thick component of rubbish together join in the combustion chamber with discharge device by pipeline and heat, when short bunker, in the combustion chamber, add other liquid, solid or geseous fuel are to guarantee the temperature of combustion chamber, make thin component of rubbish and thick component fusion at high temperature, by discharge device fused rubbish vitrification is drained in the pond then, the residue of gained melten glass shape can be used in the production of building materials.
