Description
Technical field:
The present invention relates to pond, a kind of lake bed mud oxygen-enriched air smelting gasification process and device, belong to solid waste disposal and dispose the field.
Background technology:
Natural or man-made lake pond is important multi-functional surface water resources, has functions such as irrigation, flood control, shipping, breed, to regulating the climate, keep the eubiosis important ecological functions is arranged.Bed mud is as the important component part of lake ecological environment, the pollutent of bed mud in can adsorbed water body reduces the water pollution degree, in case condition changes, N, the P that bed mud discharges is one of important nutrition source of supporting nutrition enriched shallow amber blue-green alga bloom, influences the water quality of water body; Along with the continuous development of industrial economy, the pollution of bottom mud in lake has seriously hindered the normal performance of lake function, and is therefore, significant to recovering lake ecological environment to the improvement of bottom mud in lake.
The bed mud dredging is an important means of improving pond, lake water body environment, is to implement maximum mature technologies in the bed mud control.Pond, lake dredging engineering produces a large amount of bed muds.The processing of Hu Chi dredging bed mud and utilization are the hot subjects in the current environmental protection field.Owing to contain a large amount of moisture, heavy metal, pathogenic micro-organism and parasitic ovum etc. in the bed mud,, can cause secondary pollution as mishandling.How to realize sludge stabilization, minimizing, innoxious and resource utilization, become the focus that people pay close attention to.
Pond, lake bed mud has the characteristics of biological energy raw material, contain organic matters such as a large amount of soluble saccharides, Mierocrystalline cellulose, xylogen, fat, protein, fixed carbon wherein, protium content are higher, and under the condition of empty butt, its net calorific value is about 8000kJ/kg, so have higher energy development and utility value.As certain lake dredging bed mud through ultimate analysis (empty butt): moisture 12.68%; C 20.83%; H
2: 1.86%; O
2: 12.63%; N
2: 0.84%; S:0.67%; Ash content: 50.49%.
Countries in the world extensively adopt sanitary landfill, composting process, burning, soil utilization etc. to be main processing mode in the processing of mud.Sanitary landfill faces the in short supply and masses of the land resources equipressure of resisting, difficult Buddhist monk's open question that composting also has many reality as: composting process is handled mud needs very big place, soil will be spaced, to prevent by deleterious contaminants, and the lot of energy that contains of mud itself, in this treatment process, can be wasted.Burning method can reduce the volume of mud significantly, and can utilize energy wherein to improve utilization efficiency of heat energy, owing to contain a large amount of objectionable impuritiess in the mud, be under aerobic environment, to carry out combustion reactions and burn, the gas of generation causes secondary pollution to environment.The soil utilization is based on the farmland utilization method, but after being used too much, will cause the content of the heavy metal in the agricultural land soil to raise.
Chinese patent 200710126149.4 is openly known clearly a kind of supercritical water oxidation technical finesse oily sludge that utilizes to produce the method for hydrogen-containing gas, but this invention is primarily aimed at and contains mud, and need gasification condition is controlled in the emergent pressure and temperature range of water in the technology that this invention is adopted; Chinese patent 200510041633.8 discloses a kind of coal and the biomass apparatus and method of overcritical catalytic gasification hydrogen manufacturing altogether, and this invention relates to the biomass with certain calorific value gasifies altogether with coal and produce inflammable gas, does not still relate to pond, lake bed mud.Chinese patent 200810063091.8 discloses the method for a kind of mud preparing hydrogen-rich gas by continuous catalysis gasification in supercritical water, and its process object is a sludge of sewage treatment plant.It is that main raw material mixes the method for producing industrial shaping coal with coal with the bed mud that Chinese patent 02133623.7 discloses a kind of, with the present invention moisture bed mud is mixed with coal and produces mud coal slurry, and the starting point that gasifies then is all different with technology.Chinese patent 200610030071.1 discloses and a kind of mud has been mixed the method for producing mud coal slurry with coal, and the mud of employing is sewage disposal mud, Industrial Wastewater Treatment mud and paper mill sludge etc., does not relate to mud coal slurry gasification process and technology.
Summary of the invention
The purpose of this invention is to provide kind of pond, a lake bed mud oxygen-enriched air smelting gasification process and a device, utilize the method for oxygen-rich gasification to be converted into available mixed combustible gas body the organic matter in the long-term sedimentary bed mud of Hu Chi, with the inorganics fusion in the bed mud is that solid is as pavior, to reach the purpose of eliminating environmental pollution.
Characteristic and constituent content thereof according to pond, lake bed mud, take bed mud and coal to be mixed into mud coal slurry, method with oxygen-rich gasification in vapourizing furnace is converted into the mixed combustible gas body with the organism in the bed mud, deleterious heavy metal is melt into the inorganic salt solid, as pavior, solve the pollution problem of bed mud more up hill and dale.Inflammable gas quality of the present invention is good, and purposes is wide, can be used as fuel gas-steam-generating combined cycle, also it can be carried out after part conversion and the methanation as town gas; Gasification itself is polluted few, good environmental protection; The sewage that produces seldom, a small amount of sewage can discharge after simple process; But thick, the thin slag of discharging is the making cement spike or the usefulness of paving the way both, to the environment non-secondary pollution; For a new road has been opened up in a large amount of pond, lake bed mud processing.
The bed mud that principle of the present invention: Hu Chi dredging produces becomes mud coal slurry with the coal mixed grinding, sprays in the vapourizing furnace by nozzle with oxygen enrichment, finishes moisture evaporation, burning and a series of conversion reaction of mud coal slurry in the short period of time at the utmost point:
