DEVICE FOR PRODUCING FUEL OF DYEING WASTEWATER SLUDGE IN COAL-FIRED POWER UTILITY BOILER PLANT AND METHOD THEREOF

摘要

Enter the fuel for burning the power boiler apparatus sewage sludge of coal the present invention relates to a device and a kind of method for dye wastewater,But it is more specifically for manufacturing the dye wastewater sludge in the power boiler for burning coal as the secondary fuel in coal,Woolen mill wastewater sludge,Its is entangled with one another to generate a kind of granular fuel mixture other than handling this and smoothly mixed powder material and burns the power boiler of coal immediately will pass through,It can be used for being convenient for,Not separating 10 won during drying process needs reduced energy to consume,And separation is not necessarily to install antipollution facility and remove from the smell and pernicious gas for being dried generation,The method of the final energy efficiency improved on fuel apparatus and the dye wastewater sludge for the recycling and coal-fired plant boiler for allowing to reduce environmental pollution for recycling woolen mill wastewater and sludge. ;For this purpose according to the fuel-device of the dye wastewater sludge of the power boiler installation of burning coal of the invention and incoming air in the coal pulverizer from the pulverized coal combustion delayed heat in the burning gases that boiler and an air preheater issue,Boiler and burning,In order to remove deduster of the dust in flue gas,It is that coal-fired plant boiler and the flue selexol process system being made of denitrogenation are discharged into removal inside that the flue gas of nitrogen oxide and oxysulfide, which enters fuel system,,Sludge extruder is installed adjacent with boiler and a length,It is thinning as some dye wastewaters squeeze the front and rear and the subtly adjacent nozzle of coal dust for generating residue and conveying extruder,And coal crusher installation generates residue,In the sludge extruder and coal pulverizer that the bottom of conveyer belt is installed,Its mixing and extruding for shifting the sludge and fine coal powder that decline from sludge extruder,Heap stacked on adjoining is mounted on heat exchange air, and stack group is discharged into the delayed heat for restoring exhaust gas,Wherein conveyer is arranged between boiler and air preheater to be to further include the dry coal powder mixture and grain sludge/coal mixture powder sludge storage/drumdrier for being generated by dry use for supplying a storage feeder of the coal with main fuel in the boiler with the characteristics of adjacent waste heat recycled by the heat exchanger and air. ;Furthermore,A kind of method for dye wastewater sludge enters the fuel of the power boiler device for burning coal according to the present invention,The coal dust inputted in boiler and combustion air is supplied to combustion step,Warm-up combustion-supporting air to the discharge from boiler heat burning gases waste heat the step of,The following steps are included: collecting dust in burning gases,In nitrogen compound,Oxysulfide and coal are removed the following steps are included: in combustion gas power plant boiler,Removed evil substance the described method comprises the following steps discharge exhaust gas into the fuel for burning gases inside: squeeze a length,Thin die wastewater sludge and the step for subtly crushing coal dust,Extrude and simultaneously sludge fall off sludge is spread before and after the decline of sludge it is entangled with one another so as to fine coal powder and fusion,In restoring the exhaust gas delayed heat that sludge/step coal dust intermixture realizes that a dry granular is formed,Wherein from the smell and pernicious gas that there is the step of by drying stage and Mixture Density Networks in combustion step and the dry stove generated to remove a boiler of grain sludge and coal dust to generate burn with the main fuel by introducing a boiler mix it is characterized in that it includes: more.
