Method for treating household waste carbonization and sludge drying by utilizing tunnel brick kiln afterheat

Abstract

The invention discloses a method for treating household waste carbonization and sludge drying by utilizing tunnel brick kiln afterheat. According to the method, waste carbonization and sludge drying are carried out by utilizing afterheat of cooling sections of tunnel kiln brick roasting tunnels, so that the pollution of solid waste, wastewater, soil and waste gas generated by current household waste and sludge landfill and incineration is solved; and after cooperation, pollution of solid waste, wastewater and waste gas is avoided, so that the method belongs to a closed loop process. Accordingto the method, the coal consumption caused by burning shale bricks and land utilization caused by landfill are saved and decreased, so that the method accords with the national structure adjustment and ecology promotion strategies; household waste carbonization and sludge drying are carried out by utilizing the afterheat of the cooling sections, so that fixation and the effects of low production investment and low operation cost can be realized; harmless and resourceful treatment for municipal waste is realized, so that beneficial support is provided for city development and capacity enlargement; and the kiln construction length can be decreased so as to save the kiln construction investment.

Description

technical field [0001] The invention relates to the fields of garbage carbonization, sludge drying treatment, and brick-making sintering, and specifically relates to a harmless and resource-based coordinated treatment method for utilizing waste heat in a tunnel brick kiln roasting path to urban domestic garbage carbonization and sludge drying. Background technique [0002] The fundamental purpose of waste disposal is to reduce, harmless and recycle waste. In the past, there were three methods of garbage disposal: landfill, composting and incineration. Obviously, landfill does not meet the requirements of reduction, harmlessness, and recycling; composting needs to be sorted, the environment of sorting is harsh, and the cost is high, and the sorted garbage is still garbage, and the garbage has not been completely eliminated; and, sorting How to deal with all kinds of garbage. How to recycle. Everyone is always worried about recycled products, and so on, but they have not be...

AI Technical Summary

Problems solved by technology

Use the waste heat in the cooling section of the tunnel kiln firing brick roasting path to carbonize garbage and dry sludge, which solves the pollution of solid waste, wastewater, soil and waste gas generated by landfill and incineration of domestic garbage and sludge at present, and there is no pollution after synergistic treatment The pollution of solid waste, waste water and waste gas belongs to the closed-loop process; it saves and reduces the coal consumption of firing shale bricks and the land use of landfill waste, which is in line with the national strategy of adjusting structure and promoting ecology; using the waste heat in the cooling section to carbonize and pollute domestic waste Mud drying treatment can realize the effects of fixed and low investment in production and low operation cost; it can realize harmless and resourceful treatment of urban waste, and provide favorable support for urban development and capacity expansion; it can reduce the length of kiln construction and save construction kiln invest
