Chemical engineering sludge processing system

Abstract

The invention discloses a chemical engineering sludge processing system which is characterized in that a sludge storage bin (3) is internally provided with a stirring and blanking device (4); and the chemical engineering sludge processing system is connected with a predecomposition kiln system of a novel cement dry process kiln through a sludge delivery pump (7) and a sludge high-pressure delivery pipeline (8). According to the technical scheme, the technical characteristic of a cement firing system is utilized, full and efficient innocent treatment is carried out on chemical engineering sludge, generated gas and ash residues are directly processed by utilizing the novel cement dry process kiln, waste discharge does not exist, and complicated waste gas treatment facility is not needed to be additionally arranged; and meanwhile, the implicit heat in the sludge is completely utilized, so that the purpose of carrying out complete innocent treatment, recycling treatment and complete reduction treatment on the sludge is realized.

Description

technical field [0001] The invention belongs to the technical field of combining the production of building materials and the disposal of hazardous waste in chemical production. Specifically, the invention relates to a chemical sludge treatment system. Background technique [0002] With the continuous improvement of the level of economic development and people's awareness, people's awareness of environmental protection and cement resources has been continuously enhanced. Environmental issues, resource issues and sustainable development issues have increasingly become one of the most important factors restricting social and economic development. [0003] The disadvantages of first developing the economy and then solving environmental protection and resource issues have become more and more serious. As a result, economic development will inevitably fail, environmental problems will not be solved well, and sustainable economic development will not be guaranteed. [0004] Amon...

Problems solved by technology

[0008] 1. Safe landfill method: low investment and simple operation, but there are great consequences. Hazardous substances are easy to leak and cause environmental pollution. Once the lining system fails, it will cause long-term and continuous threats to the surrounding environment and the public, and landfill The farm occupies a large amount of land, resulting in waste of land resources;

[0009] 2. High-temperature incineration method and pyrolysis method: the general principle of hazardous waste reduction, recycling and harmless treatment that meets the technical policy requirements of hazardous waste pollution prevention and control. The volume of treated hazardous waste residues can be reduced by 90%, and the weight It can be reduced by 80%, but the initial investment cost is high, the operation cost and operation technology are difficult, and the high-temperature incineration method often needs to use auxiliary fuel, which consumes a lot of energy; the pyrolysis method currently does not have a large processing capacity and is suitable for Limited range, need classification preprocessing

[0012] However, these methods cannot meet the requirements of completely reducing the volume of hazardous waste
