A Harmless Slag Treatment System

Abstract

The invention provides a harmless slag treatment system, which includes a crusher, a stirring device, a repair box, a separation pool and a filter press, the feed port of the crusher is connected with a raw material conveying device, and the outlet of the crusher is The feed port is connected with the second conveying device, the second conveying device is connected with the hopper, the feeding port of the stirring device is connected with the hopper, the stirring device can be a rotary tank mixer, and the feeding of the stirring device The port is also connected with a repair box, the discharge port of the stirring device is connected with the feed port of the separation tank, the feed port of the filter press is connected with the discharge port of the separation tank through a filter press pump, The outlet of the filter press is connected with the second conveying device. In the present invention, by setting the repairing box and the stirring device, the mixing of the dregs and the repairing liquid is more uniform, the repairing effect is more obvious, and the treated dregs can be free from pollution residues, achieving the purpose of harmless treatment.

Description

technical field [0001] The invention relates to the field of construction dregs treatment, in particular to a harmless dregs treatment system. Background technique [0002] With the continuous expansion of the urbanization process, the discharge of engineering muck has increased year by year. Most of the dregs are mainly stacked in the open air. After long-term exposure to the sun and rain, harmful substances in the garbage enter the soil through alkaline substances, resulting in A series of physical, chemical and biological reactions, or absorbed by plant roots or synthesized by microorganisms, resulting in soil pollution. During the stacking process of muck, mixed domestic garbage, under the action of temperature, moisture, etc., some organic substances decompose and produce harmful gases; at the same time, bacteria and dust in the garbage are scattered, causing air pollution; a small amount of combustible light substances Toxic substances will be produced, causing air po...

AI Technical Summary

Problems solved by technology

[0003] Engineering slag is mainly composed of mud, scattered mortar and concrete fragments, bricks and stones produced by chiseling, scrap metal, bamboo wood, waste generated in the process of building decoration, various packaging materials and other wastes, etc. , the proportion of soil is about 60%. Since the muck contains a lot of alkaline concrete, the pH value is as high as 12-13, which belongs to strong alkali and seriously pollutes the environment. It should be treated when it is reused; while the traditional The muck disposal method is landfill, stacking, etc., which not only wastes resources, but also pollutes the environment and causes secondary pollution. Therefore, a harmless muck disposal system is urgently needed
