Embodiment Construction

[0017] According to the test data of the organic sludge, it is further dehydrated and added with dry clay, dry sludge powder, sludge combustion ash, sand, glass powder, etc., targeted conditioning materials, and make it meet the requirements for brick molding. Moisture content and plasticity index are made into adobes and then fired according to the conventional internal combustion brick method to make sintered bricks for construction. Wherever sludge fuel has a way out, making solid fuel is more convenient, energy-saving and less polluting.

[0018] The organic sludge is further dehydrated and dried, and crushed into dry sludge powder, which can be used as fuel for pulverized coal furnace; after further dehydration or adding coal powder and dry sludge powder to the organic sludge to make it reach the moisture content of the briquette , use a conventional industrial briquette forming machine to press into sludge briquettes, and then dry them in a drying tower to become fuel fo...

Abstract

The invention relates to sludge-made fired bricks or solid fuel and related drying tower thereof and pertains to a solid waste treatment technical field. The invention is designed for treatment of organic sewage and sludge from domestic and industry which has the following characteristics that the rich containing of organic matter, difficulty in treatment of disease source, high heating capacity, and the containing of clay used as main mineral composition. The sewage sludge can be used to make dry sludge powder and compacted into industry coal after the adjustment of heating capacity, and can also be used as solid fuel in coal powder furnace, civil use, grate-fired furnace of industry and gasification. In the place where the sludge fuel has no market, the sludge can also be used to make fired brick, sludge drying tower, and also other materials after sludge composition adjustment, in particular be used in drying the material containing organism. The invention has low investment, simple structure, which accords with the conditions in China, and is a practical technique with thoroughly harmless treatment and the most economical resources utilization.

Description

(1) Technical field: [0001] The invention relates to the harmless treatment and resource utilization technology of sludge, and belongs to the technical field of solid waste treatment. (two) background technology: [0002] Natural sludge such as unpolluted river and lake sludge, mine sludge, and urban sewage sludge generally does not contain harmful substances, and can be directly used in farmland, foundations, sintered bricks, or landfills according to the purpose of the soil. method to be processed and utilized. Inorganic industrial wastewater sludge can also be used as soil after eliminating or controlling the harmful substances brought by the source and stabilizing it. [0003] Urban sewage sludge and food, leather and other industrial wastewater sludge are rich in organic matter, easy to rot and smell, and also contain a large number of pathogens such as microorganisms, germs, and parasite eggs, which are easy to spread diseases and are difficult to treat and utilize. ...
