Abstract
A kind of comprehensive utilization process for being sintered brickmaking of city sludge and riverway sludge, process flow steps are as follows: city sludge and riverway sludge carry out raw material crushing screening → mixing → ageing → base → stacking → after working process respectively and enter kiln sintering → cooling storage；The present invention by the poisonous and harmful element in sludge by solidification, carries out burning processing, thoroughly reduces the possibility of the secondary pollution of pollutant by carrying out reconfiguring design to city sludge and riverway sludge processing disposition；The new paragon that two kinds of solid wastes only have the processing disposition filled is opened, the amount of landfill of reduction can largely reduce the demand to land resource, original useless waste is turned waste into wealth, realizes the resource utilization of waste.
Description
Technical field
The present invention relates to the sintering of urban waste processing disposal field more particularly to a kind of city sludge and riverway sludge
The comprehensive utilization process of brickmaking.
Background technique
As Environmental protects pay attention to day by day, country puts into effect a series of related environmental protection policy in succession, city sludge,
Riverway sludge, building waste are the persistent ailments that long-standing problem urban environment is administered.The main processing mode of China's city sludge at present
It is landfill method processing, this method investment is relatively fewer, but needs land occupation, while there are the temporary nothings of many harmful substances in sludge
It eliminates, otherwise the waste pit for needing investment construction waterproof, seepage control saturating when directly filling will cause secondary dirt to environment and underground water source
Dye, does not accomplish the elimination of pollution sources also；Riverway sludge generally uses physics dehydration and drying to act on, and riverway sludge is carried out mechanical squeeze
Moisture is detached from the mud cake to form relatively dry by press-dehydrating, but the processing mode of a large amount of mud cake is not yet clear；And two kinds solid
Body waste is all individually opposite processing, does not there is ideal total solution integrated treatment；How city sludge, river are made
Mud two kinds of solid waste in road ultimately form a set of feasible disposition of solid waste processing by the integration of resource, at
For insoluble technical problem for a long time.
In view of the foregoing, the comprehensive utilization process for being sintered brickmaking of a kind of city sludge and riverway sludge is now developed.
Summary of the invention
Purpose of the invention is to overcome the shortcomings in the prior art, provides the burning of a kind of city sludge and riverway sludge
The comprehensive utilization process for tying brickmaking, by carrying out reconfiguring design to city sludge and riverway sludge processing disposition, by sludge
In poisonous and harmful element by solidification, carry out burning processing, thoroughly reduce pollutant secondary pollution possibility；Open two
Kind solid waste only has the new paragon of the processing disposition filled, and the amount of landfill of reduction can largely reduce the demand to land resource, will be former
Carrying out useless waste turns waste into wealth, and realizes the resource utilization of waste.
The present invention to achieve the goals above, adopts the following technical scheme that the sintering of a kind of city sludge and riverway sludge
The comprehensive utilization process of brickmaking, process flow steps are as follows: city sludge and riverway sludge carry out original after working process respectively
Material crushing and screening → mixing → ageing → base → stacking → enters kiln sintering → cooling storage；Specific implementation step is as follows:
Raw material crushing screening: sludge generative fuel that city sludge, riverway sludge are respectively formed after working process,
Mud cake fine powder material carries out crushing and screening, and mud cake fine powder material constitutes sintering feed, and sludge generative fuel is fuel；
Mixing: by after crushing and screening mud cake fine powder material and sludge generative fuel mix, mixed mixture is defeated
It send to ageing library；
Ageing: mixture is aged in ageing library, and various raw materials is made adequately to carry out infiltration contact, digestion time 36-
40h；
Base: the mixture after ageing is squeezed into specific adobe item under the action of extruder, by cutting machine by brick
Base is cut into specific adobe；
Stacking: after green brick forming, molding adobe is carried out into kiln stacking；
Enter kiln sintering: adobe is fired, ultimately forms finished product sintering building materials；
Cooling storage: warehouse is sent into after firing the finished product cooling of completion.
The mud cake fine powder material are as follows: 70%-80%, sludge generative fuel are as follows: 21%-30%, the above each component assemble
The sum of weight is 100%.
The beneficial effects of the present invention are: the working process of city sludge of the invention are as follows: ortho states sludge modification → broken wall →
Sludge deodorization consolidates sulphur → sludge is loose combustion-supporting → and turns over throwing sunning, is finally made sludge generative fuel；The working process of riverway sludge
Are as follows: mud impurity-removing precipitating → concentration solidification → pressurization pumping → belt type dehydration → broken crushing is fluffy, is finally made mud cake fine powder
Material；The present invention, will be poisonous and harmful in sludge by carrying out reconfiguring design to city sludge and riverway sludge processing disposition
Ingredient carries out burning processing by solidification, thoroughly reduces the possibility of the secondary pollution of pollutant；Two kinds of solid wastes are opened only to fill out
The new paragon for the processing disposition buried, the amount of landfill of reduction can largely reduce the demand to land resource, and original useless is discarded
Object is turned waste into wealth, and realizes the resource utilization of waste, this process equipment investment is small, and production capacity is big, and operating cost is cheap, cost performance
Higher, it can be achieved that a variety of solid waste centralized processings, realize unification of more giving up, more industry chains are produced, the building materials of final realization solid waste.
