Description
Technical field
The present invention relates to the treatment technology of municipal sludge, specifically a kind ofly using municipal sludge and mix and burn treatment facility and treatment process as the municipal sludge of thermal power generation auxiliary fuel.
Background technology
Along with national economy and social development, environmental pollution is day by day serious, and municipal sewage treatment obtains the great attention of government and society all circles, and new Sewage Plant is constantly built, and wastewater treatment rate significantly improves.And municipal sludge is as the byproduct of sewerage system, large, unstable, the easy corruption of its capacity, foul smelling, mud is the liquid-solid combustiblematerials of high-moisture percentage, contains a large amount of pathogenic bacterias, parasitic ovum, and the heavy metal hazardous and noxious substances such as chromium, mercury, belong to high density pollution thing.According to current technology, one ton of sewage of every processing, can produce the wet mud of the water ratio 80% of about thousandth.Must carry out harmless treatment disposal to mud.Sludge treatment generally has the modes such as compost, alkalescence are stablized, building materials utilization, soil utilization, sanitary landfill, burning.Traditional landfill disposal options can cause the waste of valuable land resources, affects surrounding environment, river course and underground water source.At present, external general sludge treating method is to adopting fluidized combustion to process after wet drying sludge, but this method complex process, facility investment is high, investment mud handling capacity every day is the sludge drying device of 150 tons, its cost is approximately 3000 yuan of ten thousand Renminbi left and right at present, has greatly limited applying of burning disposal.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of and municipal sludge can be treated to thermoelectricity fuel, and device structure simple, drop into municipal sludge little, that technique is simple, processing cost is low and mix and burn treatment facility and treatment process.
Municipal sludge of the present invention is mixed burning treatment facility and is included the conveyor that gathers materials, above the feed zone of conveyor that gathers materials, be provided with for depositing the sludge bucket of mud and being used for depositing coal-fired coal bunker, the discharge port of sludge bucket and the coal bunker respectively drawing mechanism by is separately connected with the feed zone of the conveyor that gathers materials; The discharge end of the described conveyor that gathers materials is connected to an a mixing bowl, the discharge port of a mixing bowl is connected to a discharging conveyor, a storage hopper of discharge end access of discharging conveyor, the discharge port below of storage hopper is provided with a Bidirectional belt conveyor, two discharge ends of Bidirectional belt conveyor connect respectively the defeated coal streamline of carrying for thermoelectricity fuel with two-way and are connected, by the variation of Bidirectional belt conveyor throughput direction, can distribute material to the defeated coal streamline of two-way.
The drawing mechanism that described coal bunker discharge port connects is belt feeder, is adapted to the metering output of coal-fired aggregate; The drawing mechanism that described sludge bucket discharge port connects is Shaftless screw conveyor, is adapted to the metering output of the mud material that water content is larger.
Between the discharge port of described a mixing bowl and discharging conveyor, be also provided with a tripper, the opening for feed of tripper connects the discharge port of a mixing bowl, and the discharge port of tripper is selectively connected with discharging conveyor or stockyard transfer roller.When mixing imitation frosted glass or the maintenance of defeated coal streamline without interpolation in fuel, material can be delivered to stacking place by stockyard transfer roller temporarily stacks.
Municipal sludge of the present invention is mixed burning treatment process: utilize above-mentioned municipal sludge to mix burning treatment facility, directly by wagon tremie, pour the mud of water ratio 80% into sludge bucket, after being measured by Shaftless screw conveyor, provide, fire coal is transported to coal bunker by shovel loader, belt feeder metering by coal bunker below provides, and two kinds of materials that measure is to scale sent into a mixing bowl through the conveyor that gathers materials together and stir; When the discharge port of tripper is positioned at discharging conveyor one side, the finished product material being stirred is delivered to a defeated coal streamline supply fired power generating unit through storage hopper and Bidirectional belt conveyor; When defeated coal streamline breaks down or do not need mud to add storehouse, the discharge port of tripper goes to stockyard transfer roller one side, and the finished product material being stirred carries out stockyard production by stockyard transfer roller and gets the raw materials ready.
Device and method of the present invention is by mud and coal-fired mix and blend, acquisition can be as the imitation frosted glass of mixing of thermoelectricity fuel, saved the withering step of mud, can directly utilize coal-fired unit to carry out burning electricity generation, device structure is simple, less investment, and treating processes is easy, processing cost is low.
