Waste Incineration Power Generation Solid Waste Disposal
After determining the parameters of the waste incineration power generation solid waste disposal equipment, transport the waste incineration power generation solid waste to the solid waste disposal room, and carbonize the waste incineration power generation solid waste according to the solid waste carbonization equipment selected above and combined with the disposal technology. First, the solid waste from waste incineration power generation is placed in the low-temperature carbonization chamber on the first floor of the solid waste carbonization machine for preliminary carbonization, and then it is subjected to primary carbonization treatment and secondary carbonization treatment; then the solid waste from waste incineration power generation is placed in the high-temperature carbonization chamber on the second floor Carry out complete carbonization; after the carbonization is completed, put the carbonized waste incineration power generation solid waste into the decomposition tank for reverse osmosis treatment through the ultrafiltration device, add nitric acid solution into the decomposition tank, and put lime and sodium carbonate into the decomposition tank at the same time And coagulant, nitric acid solution, lime, sodium carbonate and coagulant can decompose the carbonized solid waste, reduce the hardness and alkalinity of the solid waste, and send the decomposed solid waste to the super Filtration in membrane filter pool. After being treated by the ultrafiltration membrane tank, most of the colloids and microorganisms in the decomposed solid waste are basically removed, and the filtered solid waste can be buried or used as waste for farmland production to realize resource recovery and reuse.
During the entire waste incineration power generation solid waste disposal process, the chemicals that need to be put in include coagulants, flocculants, softeners, and sulfuric acid. This design uses ferric chloride (FeCl3) as the coagulant, and the concentration of the selected solution is 35.8% to 42.4%. The flocculant adopts powdery polymer type, and its purity is guaranteed to be above 92.5%. The purity of the softener is guaranteed to be 65% to 80%, and the sulfuric acid content is 96%. At the same time, in the waste incineration power generation solid waste disposal and dosing room, an automated polymer preparation equipment is designed and installed to dissolve solid waste incineration power generation solid waste into a liquid state, which is convenient for subsequent dosing. The waste incineration power generation solid waste is concentrated and dehydrated in the disposal room to reduce the water content to 65.5%-76.5%, and a concentration dehydration device is installed in the dehydration room to concentrate and dehydrate the waste incineration power generation solid waste The polymer flocculant is put into the device to complete the concentration and dehydration treatment of waste incineration power generation solid waste, comprehensively utilize the dehydrated waste incineration power generation solid waste, and complete the technical design of waste incineration power generation solid waste disposal.
