Embodiment Construction
[0010] The production process and specific distribution are as follows: figure 1 As shown, the main contents include: 1. Domestic waste incineration treatment; 2. Preparation of raw meal pellets; 3. Connection of flue gas pipeline and raw meal pellet drying equipment; 4. Calcination of raw meal pellets by cement kiln; 5. Raw meal pellets Treatment of evaporated gas 6, bag dust removal, etc. Through scientific and effective resource integration, the goals of energy saving, consumption reduction, cleanliness and environmental protection are achieved.
[0011] After domestic waste enters the factory's waste storage, it can be pretreated by screening, iron removal, crushing, extrusion dehydration and drying, and then incinerated. The temperature of garbage incineration is above 850 degrees. Heat energy enters the raw meal ball dryer through the exhaust port of the incinerator, and the raw meal balls are continuously evaporated under the action of high-temperature flue gas. Final...

The invention relates to a method for treating household garbage, and in particular relates to a method for treating household garbage by absorbing heat energy through raw meal nodules. The method comprises the following steps of: drying the raw meal nodules by using the high-temperature flue gas produced by burning the household garbage; evaporating the water in the raw meal nodules; enabling the raw meal nodules with reduced water content to enter a cement kiln to be calcined; after the heat energy is released, mixing the flue gas produced by burning the household garbage with the outside air, sending the mixed gas into the cement kiln for high-temperature calcination to thoroughly remove toxic and harmful substances by pyrolysis; and carrying out cloth bag dust removal and then discharging the treated flue gas into the atmosphere. The method is capable of reasonably collocating the resource superiority and combining garbage disposal with cement production, thus realizing reduction, reclamation and harmlessness of garbage disposal, and achieving the aims of saving energy, reducing consumption, being clean and environment-friendly, and benefiting mankind.
Description
technical field [0001] The invention relates to a treatment method for domestic garbage. Background technique [0002] At present, single methods such as landfill, incineration, composting, or waste-to-energy are commonly used to dispose of domestic waste. This single approach not only wastes a lot of investment in fixed assets and land resources, but also easily causes secondary pollution such as odor overflow, dioxin excess standards, ash and leachate flooding during the garbage disposal process, and brings great harm to the surrounding environment. influences. Patent application CN101628792 discloses a method of using cement kiln to process domestic waste, which solves the problem of harmless treatment of domestic waste, and uses the heat energy generated by waste incineration to dry the materials in the mill, but it only solves the problem of increasing the output of the mill The problem. After the raw material is pelletized, there is still a large amount of water tha...
