Abstract

A kind of comprehensive utilization process of city sludge and construction garbage brick, process flow steps are as follows: city sludge and building waste carry out raw material crushing screening → mixing → ageing → base → stacking → after working process respectively and enter kiln sintering → cooling storage；By carrying out reconfiguring design to city sludge and building waste processing disposition, by the poisonous and harmful element in sludge by solidification, burning processing is carried out, thoroughly reduces the possibility of the secondary pollution of pollutant；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

A kind of comprehensive utilization process of city sludge and construction garbage brick
Technical field
The present invention relates to urban waste processing disposal field more particularly to a kind of city sludge and construction garbage bricks Comprehensive utilization process.
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, Building waste is the persistent ailment that long-standing problem urban environment is administered.City sludge main processing mode in China's is at landfill method at present Reason, the investment of this method is relatively fewer, but needs land occupation, while there are many harmful substances in sludge temporarily without elimination, directly Otherwise the waste pit for needing investment construction waterproof, seepage control saturating when landfill will cause secondary pollution to environment and underground water source, not do also To the elimination of pollution sources；It is continued to develop along with city, building waste largely generates therewith, and simple landfill or air storage are not only The appearance of the city is influenced, the wasting of resources, environmental pollution are also caused, construction waste crushing sorting at present gradually occurs in various regions, will build rubbish Rubbish is broken into the aggregate of different-grain diameter, plays certain positive effect, but construction waste crushing screen out the superfine powder that comes because Amount deals with greatly also more difficult.And both solid waste are all individually opposite processing, are not had ideal whole Body solution integrated treatment；Two kinds of city sludge, building waste solid waste how is set to pass through the integration of resource, most end form It is handled at a set of feasible disposition of solid waste, becomes insoluble technical problem for a long time.
In view of the foregoing, the comprehensive utilization process of a kind of city sludge and construction garbage brick is now developed.
Summary of the invention
Purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of city sludge and construction garbage brick Comprehensive utilization process, by city sludge and building waste processing disposition carry out reconfiguring design, by having in sludge Malicious harmful components carry out burning processing by solidification, thoroughly reduce the possibility of the secondary pollution of pollutant；Open two kinds of solid wastes The new paragon of the processing disposition only filled, the amount of landfill of reduction can largely reduce the demand to land resource, will be original useless Waste turn waste into wealth, realize the resource utilization of waste.
The present invention to achieve the goals above, adopts the following technical scheme that a kind of city sludge and construction garbage brick Comprehensive utilization process, process flow steps are as follows: city sludge and building waste carry out raw material respectively after working process and be crushed 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, building waste are respectively formed after working process, Superfine powder carries out crushing and screening, and superfine powder constitutes sintering feed, and sludge generative fuel is fuel；
Mixing: by after crushing and screening superfine powder and sludge generative fuel mix, the conveying of mixed mixture 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 superfine powder of the building waste are as follows: 70%-80%, sludge generative fuel are as follows: 21%-30%, it is above each It is 100% that component, which assembles the sum of weight,.
The beneficial effects of the present invention are: the working process of the city sludge in the present 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；At the processing of building waste Reason are as follows: lath diagrid → rough and torn scalping → remove iron → artificial screening → fine crushing → dusting cover is finally made superfine powder；The present invention is logical It crosses and city sludge and building waste processing disposition is carried out reconfiguring design, the poisonous and harmful element in sludge is passed through solid Change, carry out burning processing, thoroughly reduces the possibility of the secondary pollution of pollutant；Two kinds of solid wastes are opened to only have at the processing filled The new paragon set, the amount of landfill of reduction can largely reduce the demand to land resource, by original useless waste change give up into Treasured realizes the resource utilization of waste, this process equipment investment is small, and production capacity is big, and operating cost is cheap, and sexual valence is relatively high, can It realizes a variety of solid waste centralized processings, realizes more useless unifications, more industry chains produce, the final building materials for realizing solid waste.
Detailed description of the invention
The present invention will be further explained below with reference to the attached drawings:
Fig. 1 is process flow chart.
