Summary of the invention
In order to solve the problem of above-mentioned existence, the present invention provides one way of life waste incineration slag comprehensive utilization process.
The present invention solves that the technical scheme that the problems referred to above are used is: one way of life waste incineration slag comprehensive utilization process is provided, comprises the following steps:
(1), use vibrosieve to be sorted away by imperfect combustion impurity, obtain surplus materials A；
(2), using tramp iron separator to be removed by the metal object magnetic-adsorption in substance A, obtain surplus materials B, open water circulation system, described water circulation system is connected in tramp iron separator；
(3), using disintegrating machine that substance B is carried out break process, obtain finely ground particle substance C, described water circulation system is connected in disintegrating machine；
(4), using big screen cloth to filter substance C, sorted away by large granular impurity, obtain surplus materials D, described water circulation system is connected with big screen cloth；
(5), by material D being flowed into collection Sha Chizhong, make the aqueous water being blended in material D in processing procedure float over upper end, solid slag is deposited at the bottom of pond；
(6), using husky water separator to be separated by the pulp water in material D, the solid slag after separating drains the raw material E after being processed.
Further, step the most also include step (7), by raw material E and stone, cement, vat grey one or several mixing, construction material is produced through high-pressure molding, stone, cement, vat grey etc. assist auxiliary material and the raw material E after burning disposal through mix and blend, can become building material requested.
Further, the construction material produced described in includes brick, as long as the material after mix and blend being carried out production and processing by external equipment mechanism, the most large-scale automatic brick-equipment in above-mentioned, then just can be recycled by the final raw material after waste incineration.
Further, the tramp iron separator that step is (2) described, including one-level tramp iron separator and two grades of tramp iron separators, tramp iron separator is that in the rubbish after make use of magnetic force attraction principle to burn, the metal substances matter absorption of residual removes, and uses the removal that one-level tramp iron separator and two grades of tramp iron separators can be more deep clean.
Beneficial effects of the present invention: use domestic waste incineration residue comprehensive utilization process of the present invention, by sorting metal, pulverized particles, screening, final building material is obtained after draining process, the secondary recovery realizing house refuse utilizes, further, by outside brickmaking machine, final building material is carried out deep processing, can obtain building required finished bricks, make nature rubbish that garbage slag be made after this technique fragment of brick, a kind of process house refuse effectively being utilized as resource and disposing is provided, realize economic circulation development, alleviate energy shortage, promote the well-being of mankind.
Accompanying drawing explanation
Fig. 1 is the flow chart of domestic waste incineration residue comprehensive utilization process specific embodiment of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further illustrated.
As shown in Figure 1, it is provided that one way of life waste incineration slag comprehensive utilization process, this technique uses and the slag after waste incineration carries out PROCESS FOR TREATMENT, then the final material processed is carried out brickmaking processing, obtains building materials finished bricks.
This technique comprises the following steps flow process:
