Along with the development of national economy and society, 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, its capacity is large, unstable, easy corruption, foul smelling, and 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 the 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 to mud disposes.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 about 3000 yuan of ten thousand Renminbi 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 to be simple, input municipal sludge little, that technique is simple, processing cost is low is mixed and burnt treatment facility and treatment process.
Municipal sludge of the present invention is mixed the burning treatment facility and is included the conveyor that gathers materials, be provided with to deposit the sludge bucket of mud and be used for depositing coal-fired coal bunker above the feed zone of conveyor that gathers materials, sludge bucket be connected with coal bunker discharge port respectively the drawing mechanism by separately be 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, storage hopper of discharge end access of discharging conveyor, be provided with a Bidirectional belt conveyor below the discharge port of storage hopper, 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 larger mud material of water content.
Also be provided with a tripper between the discharge port of described a mixing bowl and discharging conveyor, the opening for feed of tripper connects the discharge port of a mixing bowl, and the discharge port of tripper selectively is connected with discharging conveyor or stockyard transfer roller.Stack the place and temporarily stack when need not to add in the fuel when mixing imitation frosted glass or the maintenance of defeated coal streamline material to be delivered to by the stockyard transfer roller.
Municipal sludge of the present invention is mixed the burning treatment process: utilize above-mentioned municipal sludge to mix the burning treatment facility, directly pour the mud of water ratio 80% into sludge bucket by wagon tremie, by providing after the Shaftless screw conveyor metering, fire coal is transported to coal bunker by shovel loader, provided by the metering of the belt feeder below coal bunker, two kinds of materials that measure are to scale sent into a mixing bowl through the conveyor that gathers materials together stir; When the discharge port of tripper was positioned at discharging conveyor one side, the finished product material that stirs was delivered to a defeated coal streamline supply fired power generating unit through storage hopper and Bidirectional belt conveyor; When defeated coal streamline broke down or do not need mud to add the storehouse, the discharge port of tripper went to stockyard transfer roller one side, and the finished product material that stirs carries out stockyard production by the stockyard transfer roller and gets the raw materials ready.
Device and method of the present invention is by the mix and blend of mud with fire coal, 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.
