Description
Technical field
The present invention relates to a kind of processing and method of comprehensive utilization of building waste.
Background technology
The processing method of building waste normally adopts landfill disposal at home and abroad at present, the building waste accumulating eliminate-incorporate-land that a plurality of Waste Landfill Site offered at present as the Guangzhou and a capacity preparing to build in the dragon Gui Yongxingcun expropriation of land of Taihe county, Baiyun District, Guangzhou City town are 1516 ten thousand steres, 460 mu of preliminary expropriations of land, go out huge fund by government, have only 6 years service life.Therefore Guangzhou government need continue to drop into a large amount of funds for handling building waste, takies a large amount of land resource, also can environment be impacted, and be a continual difficult problem.At present, China allows of no optimist to the processing and the administrative situation of building waste, the situation is tense, arranging, leave about phenomenon as the unrest of the current building waste in Guangzhou happens occasionally, there is report often to have the construction ship illegally to arrange the surplus mud of building and goes into the Zhujiang River, will all constitute a threat to Zhujiang River water quality, ecology and citizen drinking water source if things go on like this.And for example, Chinese Central Television's news channel was once reported, Tianjin utilizes the building waste mound design to make the method in border, take up an area of more than 30 ten thousand square metres expensive several ten million yuans, not only expended mint of money but also taken valuable land resource, environment, ecology and the civic living space of Tianjin constituted a threat to.For another example, China building newspaper had reported once that construction and decoration rubbish in Beijing's was stolen, disorderly fallen and Beijing will be provided with the dissolve situation of building waste of two, 30 eliminate-incorporate-lands every year, Beijing building waste administrative department represents, the integrated treatment utilization of present building waste also is in the desk study stage, so most of building wastes just carry out simple landfill, as seen, building waste is very serious to the influence of problems such as Pekinese, China capital environment, ecology, land occupation resource, fund and management; For another example, the design capacity in building waste filler storehouse, Hong Kong such as Tseung Kwan O's filler storehouse is 1,080 ten thousand tons, storage has reached 7,500,000 tons now, filler storehouse, Tunmen design capacity is 6,500,000 tons, storage has reached 4,500,000 tons now, the Hongkong government has been that building waste filler Kuku is completely for suffering from worry, for this reason, confer with Guangdong Province and to reach 3 years and adopt the cross-border sea of filling out of building waste, and prepare in the Taishan, Guangdong pilot, the expectation brief fee is crossed hundred million Hongkong dollars, in fact, this way will expend huge fund for a long time, be not the way that tackles the problem at its root, because long distance, super amount transportation building waste is to marine transportation, interior ground marine ecology and environment will cause immeasurable destruction and influence.In sum, the processing of building waste is a problem that urgency is to be solved, and does not have a processing cost cheap at present as yet, can carry out the circulation comprehensive utilization to all materials after handling, and pollution-free, meets the integrated conduct method of the building waste of environmental protection.
Summary of the invention
The objective of the invention is to handle existing difficult problem and to propose a kind of processing cost cheap at present building waste, can carry out the circulation comprehensive utilization to all materials after handling, meet the integrated conduct method of the building waste of environmental protection and sustainable development idea.
1. the processing method of building waste proposed by the invention comprises following treatment step:
(1) earlier with after the suitable fragmentation of building waste, with metal species wherein, bamboo wood class and plastic materials sorting detect, then surplus material is poured in the service sink of lattice screen frame (unit) with three grades of layerings, water cleans and stirs, the sieve aperture of described three fraction diagrid framves from top to bottom dwindles step by step, material is after the lattice screen frame (unit) screening of three grades of layerings, be separated into cement mortar from the bottom to top, granule sandstone grain, middle particle sandstone grain and large-block material, discharge by the floss hole of each layer respectively, wherein, granule sandstone grain, middle particle sandstone grain and large-block material are transported to each specified point with ribbon conveyer respectively and stack standby, described cement mortar then is drained into multi-stage mechanical separating sieve production line, by vibratory sieve or roller sieve and cooperate the high-pressure pump water spray to material flushing proceed screening, with mud in the cement mortar and sand, the stone grain separates, the sand that to separate then, the stone grain is transported to specified point with ribbon conveyer and stacks standbyly, precipitates and mud is entered sedimentation basin;
(2) will deliver to crusher in crushing again through the large-block material that above-mentioned category filter obtains, three grades of screen frame (unit) sizing screenings that the material after the fragmentation dwindles successively through sieve aperture again, it is standby to be separated into powder, granule sandstone grain, middle particle sandstone grain and bulky grain sandstone grain.
(3) mud in the sedimentation basin carries out drying through post precipitation with the wet mud that drains water, becomes tonerde standby, and it is recycling simultaneously the water of discharging to be entered circulating water pool.
In the present invention, the aperture of three fraction diagrid framves in the step 1, can be by following specification limit grading design: the aperture of top layer screen frame (unit) be 10～20cm, and the aperture of two layers of screen frame (unit) is 5～10cm, and the aperture of three layers of screen frame (unit) is 1～5cm.
The aperture of three grades of screen frame (unit)s in the step 2, then can be by following specification limit grading design: the aperture of one-level screen frame (unit) be 3～6cm, and the aperture of secondary screen frame (unit) is 1～3cm, and the aperture of three grades of screen frame (unit)s is 0.2～1cm.
In step 1, the cement mortar that orlop produces can be discharged by automatic plasma discharge mouth, and also available mechanical pump is discharged cement mortar; Its three fractions diagrid frame can select for use the mechanical picker of vibratory sieve, roller sieve or other types to screen, and every grade of sieve can cooperate with the high-pressure pump water spray when screening material is washed to improve the cleaning performance of screening effeciency and material.
In the sedimentation basin of step 3, mud sediment and the water that separates can make its enter carry out in the circulatory pool recycling.
The building waste material is after the inventive method is handled, except that the recyclable utilizations of material such as old metal, bamboo and wood and waste plastics that sorting in advance detects, the various materials that produced all can fully utilize: the various sand that obtain at step 1 category filter, stone grain and screening obtains in step 2 powder and large, medium and small particle sandstone grain can be according to its granule size respectively as aggregates for building, system concrete and recycling cement concrete and the material of building the road; The resulting clay of step 3 then can be used for brickmaking, potting, as the light ceramic aggregate, also can be used to make the purposes such as colored mud of plantation usefulness.
The processing procedure of this method, owing to be water dissolving, cleaning building waste, category filter under the recirculated water effect, classification is broken, and processing cost is cheap, can carry out the circulation comprehensive utilization to all materials after handling, and method safety can reduce pollution to greatest extent.Use this method to handle building waste, can be country and save substantial contribution, save a large amount of land resources, help preserving the ecological environment, promote sustainable economic development.
