Description

[Technical Field]

[0001] The present invention relates to the technical field of environmental engineering, and more particularly to a system and process for reducing multi-media pollution and carbon emissions used in industrial kiln sludge treatment. [Background technology]

[0002] Municipal sludge is a by-product of treating wastewater from urban areas. It has a complex composition, high water and organic matter content, and contains contaminants such as heavy metals, toxic substances, and pathogenic microorganisms. If not properly treated, it will cause serious environmental pollution. As the amount of wastewater discharged from urban areas increases, the amount of sludge discharge is constantly increasing, and the problem of safe treatment and disposal of sludge is becoming more and more prominent.

[0003] Currently, most municipal sludge treatment methods involve landfilling, aerobic composting, anaerobic digestion, incineration, and integrated treatment using industrial furnaces and kilns. Due to the large landfill area, increasingly limited landfill capacity, high sludge dewatering costs, and environmental risks, landfilling processes are no longer able to meet the needs for sludge detoxification. While aerobic composting and anaerobic digestion can fully utilize the organic matter and nutrients contained in sludge, they have long operating cycles and are unable to reduce or remove toxic heavy metals and persistent organic pollutants, resulting in low resource utilization and limiting the development of this technology. Sludge-only incineration requires specialized incinerators, which require large inputs, high operating costs, and secondary disposal of residues. In recent years, the use of industrial furnaces and kilns for coordinated treatment of sludge and other solid waste has become an important sludge treatment method. Sludge can partially replace fuel, and industrial furnaces and kilns can fully incinerate the organic matter in sludge. They also have relatively complete flue gas purification systems, which significantly reduce input and operating costs compared with sludge incineration alone. However, sludge has complex components and contains harmful elements such as heavy metals and chlorine. When sludge is directly coordinated with industrial furnaces and kilns such as cement kilns and brick kilns for coordinated treatment, these elements can accumulate in the cement, brick, and other products, affecting product quality and leading to difficult and expensive disposal of flue gas pollutants. Summary of the Invention [Means for solving the problem]

[0015] The technical principle of the present invention is that in the sludge treatment unit, sludge moves from top to bottom on six layers of downwardly inclined grates, and high-temperature exhaust gas transported from the industrial furnace kiln production unit flows from bottom to top in the opposite direction to the sludge. The high-temperature exhaust gas has a temperature of 700-900°C. During the sludge movement, it sequentially undergoes drying (100-250°C), pyrolysis (250-700°C), and activation (700-900°C).

ASC / HAP-S can be used in the furnace of industrial kiln production units and the adsorption section of multi-pollutant cooperative control units to simultaneously remove multiple pollutants such as heavy metals, fluorides, chlorides, VOCs, dioxins, and malodorous substances from exhaust gases. ASC / HAP-S also reduces the amount of F in the saturated adsorption tail solution. - , Cl - , SO4 2- , NO3 - It can remove major pollutants such as heavy metal ions and organic matter, and can purify and recycle the exhaust liquid.The adsorbent reduces the interfacial tension between the pollutants and the absorbent through acid-base neutralization, oxidation-reduction, chemical precipitation, diffusion-dissolution processes and the principle of "like dissolves like", inhibiting the formation of liquid crystal phases and playing a role in cleaning, while also removing pollutants such as sulfur dioxide, fluoride, HCl, nitrogen oxides, heavy metals, VOCs, dioxins and malodorous substances in the exhaust gas. [Effects of the Invention]

[0017] To summarise the above, the present invention has the following advantages: The system for reducing multi-media collaborative pollution and carbon emissions used in the treatment of industrial kiln sludge provided by the present invention fully utilizes the heat energy of the exhaust gas from the industrial kiln to dry, pyrolyze and activate the sludge in stages. The generated pyrolysis gas / tar and gaseous products from the activation stage are fed into the kiln as fuel, partially or completely replacing coal / natural gas as fuel. The production and activation of sludge charcoal are all carried out using the heat energy of the exhaust gas from the kiln and oxidizing components such as O2, CO2 and H2O, without the need for additional heat or activation media. The activated sludge charcoal can be fully used to produce the economical and highly efficient multi-functional carbon-based adsorbent ASC / HAP-S, which can simultaneously remove multiple pollutants from the exhaust gas and saturated adsorption tail solution. The removal rate of exhaust gas particulate matter, sulfur dioxide, nitrogen oxides, fluorides, HCl, heavy metals, VOCs, dioxins and malodorous substances reaches more than 90%, meeting emission standards and realizing the reduction of solid-gas-water multi-media collaborative pollution and carbon emissions. The method for treating industrial kiln sludge of the present invention achieves the recycling of heat / materials from exhaust gas, the neutralization, reduction and recycling of sludge, and the recycling of pollutants, thereby achieving interrelated environmental protection efforts, compact structure, low energy consumption, low input costs, simple technology and easy control, stable and reliable operation, high purification efficiency, and coordinated effects on pollution and carbon emission reduction.
