1. Solution Introduction
Municipal sludge, which is the byproduct of urban drainage system, mainly resulted from the urban drainage system, including sludge of drainage pipe, pump station, and sewage disposal plant. The sewage plant is the main source. The sludge is featured by high content of organic matter (60%~80%), fine particle (0.02~0.2mm), low density (1.002~1.006g/cm3), high moisture content, poor dehydration property, and unstable property, vulnerable to corrosion and pollution.
The sludge from sewage disposal plant is rich in nitrogen, pnicogen, and organic matter, but these elements are not only featured with high moisture content, vulnerable to corrosion and horrible to smell, but also contain numerous pathogenic bacteria, parasitic ovum, and heavy metal such as chrome, mercury, and non-degradation toxics and harmful carcinogen such as polychlorinated biphenyl and dioxins. If the remaining sludge is not removed from the sewage disposal system in time, it will influence the sewage disposal and even result in sewage disposal plants shut down; If the remaining sludge is discarded or deposited carelessly, it will lead to secondary pollution to environment. How to properly disposal the large quantity of deposited remaining sludge has become the urgent problems for many district governments of China at present.
The disposal method based on incineration is the most complete, fast, and economic method for sludge treatment at present; Through this method, all organic matters can be carbonized so as to minimize the volume of sludge (the volume can be reduced by 70%, even excess 90%) and the energy of sediment can be transformed into electric energy or heat energy to make waste profitable and to make a good use of the sludge.
2. Process Flow
The process of Municipal Sludge Decrement and Innoxious Disposal by Direct Incineration
The FLSP S valve sludge pumps, produced by HC FLOURISH INDUSTRY Co., Ltd., can transfer the dewatered sludge in a totally-enclosed way to the treatment termination of the existing urban facilities (e. G. Cement rotary kiln of cement plant, boiler of thermal power plant cycle fluidized bed or pulverized coal furnace ball mill, garbage incinerator of rubbish power plant, etc. )
The distinctive strengths of direct incineration:
1) Smaller area, low treatment cost.
2) A relatively safe method for sludge treatment due to the volume of remaining sludge can be reduced to a minimum and thus a small volume needs to be treated.
3) The treatment speed is very fast by incineration, no long-term storage will be required.
4) All organic matters can be carbonized and pathogen killed.
The process can produce about 100-ton dewatered sludge with the moisture content of 80% per day, and it also applicable to the sludge direct incineration project. We will provide you with full services such as complete program design, technical support, and equipment.
The Process of Sludge Decrement and Innoxious Disposal by Semi-desiccation Incineration
As the process flow shown, the sludge from sewage disposal plant is transferred to the sludge silo after simple mechanical dewatering, and then transferred to the drying equipment for semi-desiccation by sludge clean storage and transportation system, the desiccated sludge will be transported to the incineration equipment for power generation and the produced heat will be recycling used as the heat source of drying equipment.
Technical Features:
1) Zero heat source cost: The use of the waste heat from boilers as heat source realizes zero heat source cost,
2) Direct contact drying method:
3) Low temperature drying technique:
4) No influence on the operation of incineration equipment:
5) No requirement for land resource: The process based on nearby heat source needs no additional land.
6) Complete decrement:
