Principle of the present invention is:
The high-temp circulating ash that separates at the circulating fluidized bed incinerator cyclonic separator distributes through the grey distribution valve of heat, and a part enters material returning device and directly returns burner hearth, and another part enters particle drier; Water ratio is broken up the back and is added inlet and add from being located at wet mud on the particle drier in bulk the putting of the wet mud economy-combat between the 60-90%; Particle drier is the bubbling fluidized bed formula, and the bottom feeds fluidizing agent, and hot grey distribution valve branches to the direct and wet mud blending of high-temp circulating ash of particle drier, heating and dry wet mud.
By regulating the fluidising air velocity of hot grey distribution valve first feed chamber, second feed chamber and first discharge chamber, second discharge chamber, circulating ash can be distributed directly returning burner hearth and enter between the particle drier, thereby the high-temp circulating ash amount that control enters particle drier, the particle drier exhaust temperature is controlled at 80-150 ℃, and provide enough heat with wet sludge anhydration to water ratio 5-20%.Can increase the regulation range of hot grey distribution valve by in circulation loop, adding inert bed material (as sand), strengthen its regulating power the particle drier exhaust temperature to increase the mode of global cycle ash amount; Wet mud in particle drier with the direct blending of circulating ash, be heated, the contained humidity evaporation is dried to the dewatered sludge that water ratio is 5-20%, sends burner hearth with circulating ash back to by material returning device and burns.
When the height of direct returning charge mouth of heat ash and dewatered sludge returning charge mouth did not wait, the gaseous tension of first overflow port and second overflow port did not wait, and can come the balance circulating ash directly to return burner hearth and the resistance to flow that flows into the particle drier two-way by the position of spreader plate.When the direct returning charge mouth of heat ash was higher than dewatered sludge returning charge mouth, the first overflow port pressure was lower, and spreader plate should be less than 1 with the ratio of the two-part area that the projection of separator dipleg on first feed chamber and the second feed chamber bottom surface is divided into; Otherwise then should be greater than 1.
Wet mud contained humidity major part is evaporated out in particle drier, draws from the particle drier top with the particle drier fluidizing agent; The particle drier exhaust is isolated after fine powder and dust, water cooler condensation go out water of condensation through pulverized-coal collector, through the blower fan pressurization, sends particle drier back to as the particle drier fluidizing agent and recycles again, and part is sent into burner hearth and burned; Isolated fine powder of pulverized-coal collector and dust are sent burner hearth back to by mechanical transport mode or strength mode and are burned, and the water of condensation that the water cooler condensation goes out is sent sewage work back to and handled.
The drying process of wet mud carries out in particle drier, the heat that utilizes the burning of mud that high-temp circulating ash brings into and auxiliary fuel to produce comes the mummification mud that wets, wet mud is the particulate state dewatered sludge of 5-20% by mummification, return burner hearth with circulating ash again and burn, burn in the high-temperature flue gas that produces and only contain a small amount of water vapor; Most of moisture in the wet mud is discharged from the outlet of particle drier with the form of water vapour, water vapour is condensed into water in water cooler, can send sewage work back to handles, particle drier exhaust through the dedusting dehumidifying can recycle in closed circulation, also can send into the burner hearth burning disposal, the gaseous emission that peculiar smell is arranged that produces in the time of can avoiding sludge drying is in environment.
The wet mud burning treatment apparatus that has particle drier provided by the invention has following advantage: break through that first mummification is burned again, two patterns that process is independently carried out separately, the drying and incineration of mud is combined, concentrate in the incorporate device and carry out, saved because of material cooling and transported calorific loss and the power consumption that causes, simplify the anhydration and incineration treatment process of wet mud greatly, simplified anhydration and incineration equipment; Wet sludge anhydration institute heat requirement comes from the burning liberated heat of mud and auxiliary fuel: hot particle directly contacts in particle drier with wet mud, and heat transfer has been strengthened in fully blending, makes that wet mud is heated rapidly, drying; For the pure burning of wet mud, adopt device of the present invention, the wet moisture percentage in sewage sludge upper limit that allows to pure burning improves; Add the burning of the wet mud of high-moisture percentage of auxiliary fuel for needs, adopt device of the present invention, can reduce the addition of auxiliary fuel, save running cost; Circulating fluidized bed incinerator adopts ciculation fluidized incendiary mode, has the NOx of supression and generates and desulfurizing function; Moisture major part contained in the wet mud is no longer with burning the high-temperature flue gas discharging that produces, but concentrate in the cryogenic gas of particle drier discharge, reduced the calorific loss of system, reduced the consumption of incinerator auxiliary fuel or improved the upper limit that need not add the wet moisture percentage in sewage sludge that auxiliary fuel burns; The gas that produces in the sludge drying recycles or sends into burner hearth after treatment and burns, and makes the gas that does not discharge peculiar smell in the treating processes.
