Problems solved by technology

It is a thick substance between liquid and solid, which can be transported by pump, but it is difficult to separate solid and liquid by settling
[0003] After the sludge without proper treatment and disposal enters the environment, it will directly bring secondary pollution to the water body and the atmosphere, posing a serious threat to the ecological environment and human activities.
The main environmental problems are: ①High moisture content of sludge: causing high transportation costs, large storage area, squeezing landfill storage capacity, etc.; ②Bacterial growth: not only causes visual pollution, but also provides resources for the growth of other harmful organisms. ③Air pollution: The sludge piled in the open air emits foul smell and odor, exposed to the sun and wind, and the pollutant particles will cause air pollution; ④Polluted water body: After soaking and dissolving in water, the pollutants flow into the river along with the sewage, which will cause air pollution. Contaminate surface water and enter groundwater; ⑤ Contain heavy metals
However, the heavy metals in the residue produced by the general incineration method of solid waste have leaching toxicity, and they need to be disposed of by solidification and landfill.

Embodiment 1

[0036] Such as figure 1 Shown: crush industrial organic solid waste to 0-15mm for later use;

[0037] Take 650kg of sludge (water content 90%), add 300kg of industrial organic solid waste, 50kg of chlorine absorbing agent, stir and mix with a double-shaft mixer, transport the mixed material to the buffer warehouse, and mix it with a screw conveyor. The material is sent to the incinerator, and is ignited and incinerated at the same time. The incineration temperature is controlled at 1000°C±50°C. The incineration process is completed under the action of the exhaust fan. The high-temperature flue gas generated during the incineration process enters the dryer for sludge drying. After being treated by the flue gas purification system, it is discharged up to the standard.

Embodiment 2

[0039] Such as figure 1 Shown: crush industrial organic solid waste to 0-15mm for later use;

[0040]Take 800kg of sludge (water content 90%), add 400kg of industrial organic solid waste, 60kg of chlorine absorbing agent, stir and mix with a double-shaft mixer, transport the mixed material to the buffer warehouse, and pass the material through the distribution roller. Put it into the box-type sintering machine, and ignite and incinerate at the same time. The incineration temperature is controlled at 1000°C±50°C. The incineration process is completed under the action of the exhaust fan. The high-temperature flue gas generated during the incineration process enters the dryer for sludge drying. After being treated by the flue gas purification system, it is discharged up to the standard.

Embodiment 3

[0042] Such as figure 1 Shown: crush industrial organic solid waste to 0-15mm for later use;

[0043] Take 700kg of sludge (water content 90%), add 350kg of industrial organic solid waste, 55kg of chlorine absorbing agent, stir and mix with a double-shaft mixer, transport the mixed material to the buffer warehouse, and pass the material through the distribution roller. Put it into the vertical walking sintering machine, and carry out ignition and incineration at the same time. The incineration temperature is controlled at 1000°C±50°C. The incineration process is completed under the action of the exhaust fan. The high-temperature flue gas generated during the incineration process enters the dryer for sewage After the mud is dried, it is treated by the flue gas purification system, and then discharged up to the standard.

Abstract

The invention provides an industrial organic solid waste and sludge high-temperature incineration harmless treatment method. Technologies of an incineration furnace, a box sintering machine and a vertical stepper sintering machine are used for performing high-temperature incineration harmless treatment for industrial organic solid wastes and sludge through such processes as crushing, drying, burdening, uniform mixing, feeding (distribution), ignition, incineration, residue collection and smoke purification of the industrial organic solid wastes; when the harmless treatment is realized, the heat energy of the sludge and the organic industrial solid wastes is fully used; and the residues after harmless treatment can serve as construction materials, so that the purpose of harmlessness, stabilization, reduction and recycling treatment of the industrial organic solid wastes and the sludge is realized.

Description

technical field [0001] The invention belongs to the field of solid waste treatment, and in particular relates to a harmless co-disposal method for high-temperature incineration of industrial organic solid waste and sludge. Background technique [0002] Sludge is the solid sediment produced in the sewage treatment process. It is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. The main characteristics of sludge are high water content (up to 90%), high content of organic matter, easy to rot and smell, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. It is a thick substance between liquid and solid, which can be transported by pump, but it is difficult to separate solid and liquid by sedimentation. [0003] Sludge that has not been properly treated and disposed of enters the environment, directly causing secondary pollution to water bodies and the atmosp...
