Abstract

The invention discloses a technology for manufacturing brick by using dried sludge. The process comprises the following steps: stirring mixed materials; pulverizing raw materials by jaw breaking and hammer breaking; evenly stirring; screening the pulverized mixed material by a vibrating screen; carrying out upward mixing and rolling lamination on the mixed material screened by the vibrating screen; putting into a brut cellar; conveying the aged raw material into a shaper by a conveyer belt to shape the blank; conveying into a drying kiln for drying by a cutting, stacking and transporting car; then, sintering in a calcining kiln; and obtaining common sintered bricks, porous bricks or hollow bricks after the sintering is finished. According to the technology, sludge instead of clay is added into various raw materials. On the aspect of producing sintered bricks with high doping volume by utilizing municipal sludge, the maximum municipal sludge doping amount can reach 50%. The technology has obvious breakthrough on the aspects of sludge decrement and reclamation, and sludge is consumed to realize the purpose of changing waste material into things of value.

Description

technical field

[0001] The invention belongs to the harmless treatment and resource utilization technology of urban sludge, in particular to a brick-making process using dried sludge. Background technique

[0002] Municipal sludge refers to the solid waste generated during the treatment of urban domestic sewage and industrial wastewater, and is a regular product of urban sewage treatment plants. This sludge has a high water content, is perishable, has a strong odor, and contains toxic substances such as dioxins, bacteria, parasite eggs, and heavy metals. Therefore, it is necessary to carry out harmless treatment and reuse of sludge, and how to make full use of the dried sludge is also an environmental protection problem that needs to be solved urgently. Usually, the sludge is used for the following purposes after being dried by drying equipment: it is directly mixed with raw coal for combustion and utilization, so that the coal consumption of the boiler is reduced and the e...
