Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Refer to Fig. 1, a kind of full anhydration system of the mud combining with biomass fuel, including mud feeding system, dirt
Mud drying system and exhaust treatment system, mud feeding system includes mud hopper, metering conveyor and the spiral being sequentially connected
Feeder, sludge dry system include two grades that the primary drying machine that is connected with screw feeder is connected with primary drying machine dry
The air stove that the biomass boiler that dry machine is connected with primary drying machine is connected with secondary drying machine, exhaust treatment system include and
The spray scrubber that the cyclone separator that mud hopper connects is connected with cyclone separator.
In mud feeding system, the mud in mud hopper enters metering conveyor, is then fed in screw feeder.
Screw feeder, primarily to accurate measurement and add material, by the method for operation of VFC, is turned by metering screw
Speed is determining dosage.
The mud of 80% moisture content is transported to primary drying machine, and steam is delivered to primary drying by biomass fuel boiler
The moisture content of mud is down to 55% about from 80% after heating by machine, is that succeeding level-two mummification creates favorable conditions.Biomass boiler
Using fuel be dewatered sludge.
55% water content sludge is added in secondary drying machine, will be defeated for the hot blast producing in burning process by air stove
Enter secondary drying machine, be dried, 800 DEG C of drying machine input gas temperature, outlet temperature is 110 DEG C.
The dust that cyclone separator separation waste gas is taken out of, efficiency of dust collection typically 90%, the dust of collection directly with mummification dirt
Mud is mixed as product.
Spray scrubber inhales tower using uprightly reverse-flow washing, has a gas-liquid separation dress on the spray system upper strata of scrubbing tower
Put, this segregation apparatus is to separate absorbing liquid, block and enter blower fan system.
Washing absorption liquid circulating device is by circulating pump, nonchoking nozzle, jet pipe, cyclic water tank, solid-liquid separator, pressure gauge
Deng assembly composition.The presence of the uniform of water distribution and water pollution granule is take into account during the design of washing absorption fluid circulation.Pipe
Be mounted with road solid-liquid separator and using being not easily blocked, the spiral nozzle of easy accessibility.Washing absorption liquid circulating device is by electricity
Control cabinet controls operation.The pump operating cycle that closes pacifies button, and circulating pump operates.The neutralizer of cyclic water tank is divided by circulating pump, solid-liquid
From device, jet pipe, nonchoking nozzle, arrive cyclic water tank again it is achieved that the uninterrupted circular flow of neutralizer and oxidation solution.
Every grade of cyclic water tank of spray scrubber is equipped with moisturizing electromagnetic valve, automatic liquid level ball-cock assembly one.Moisturizing electromagnetic valve is subject to
Automatic liquid level instrument control system, when liquid level is in low level, automatic liquid level instrument is opened to moisturizing solenoid signal, moisturizing electromagnetic valve, to
Cyclic water tank moisturizing.When liquid level unit is in a high position, automatic liquid level instrument, to moisturizing solenoid signal, moisturizing closed electromagnetic valve, stops
Only moisturizing.And have independent discharging of waste liquid system.Each system sewage draining exit, ball valve.Circulation fluid circulation one timing of cyclic water tank
Between after need discharge.
Advantage of the present utility model is as follows：
1. product can send into power plant as biomass fuel, and also entrance system capable of circulation is burned as pre-heating fuel
Dispose, the mummification energy used is essentially biomass fuel, with low cost；
2. whole set process facility floor space is little, high degree of automation, easily realize steady and continuous and produce；
3. product can adjust mud extraction moisture content according to final recycling approach, realize resources optimization and utilize.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of creating design without departing from this utility model, some deformation can also be made and improve, these broadly fall into this practicality
New protection domain.
