Description
Technical field: the utility model relates to a kind of fluid bed medical refuse burning boiler, particularly a kind of multiple stage fluidized-bed medical refuse burning boiler.
Technical background: the clinical refuse in the medical waste, perform the operation residual thing, poisonous cotton balls etc. contain nuisances such as a large amount of germs, bacterium and chemical agent, be a kind of to the great hazardous waste of environmental hazard, the harmfulness of its viral germ is tens times even hundreds of times of house refuse, it has been listed in the Basel Convention of control hazardous waste transboundary movement and disposal thereof in the world, China also classifies it as first of " national hazardous waste register ".If take the landfill the same, burning mode to handle this hazardous waste with house refuse without specially treated, not only will cause contamination accident, also will bring long-term potential hazard, the harmless treatment that must seal to the water source and the soil environment in area.According to the statistics made by the departments concerned, the generation of China's medical waste continues to increase, and its average growth rate is 19%-25%, and this is one is worth vigilant numeral! As effectively not handling, will bring even more serious secondary pollution, therefore must develop the medical waste total system, to satisfy the needs that hospital waste focuses at the medical waste characteristic.
Burning is that rubbish subtracts a kind of effective ways that appearanceization, innoxious, energy are handled and utilized, and recent two decades comes, and along with the development of low exhaust gas emission incineration technology, has made the preferred manner of burning as Waste disposal.And China does not still have special-purpose burning facility at present, and most incinerator for medical garbage exist incomplete combustion, and recuperation of heat difficulty and secondary pollution are serious, problems such as cost height.
Summary of the invention: the purpose of this utility model is for solving the incomplete combustion that present medical waste exists in handling, and problems such as recuperation of heat difficulty, secondary pollution are serious, cost height provide a kind of multiple stage fluidized-bed medical refuse burning boiler.This product adopts the multistage incineration technology to handle medical waste at the characteristics of medical waste.Promptly having utilized fluid bed low-temperature burning good stability, the bed inner transmission matter advantages such as strong, cross section thermic load height, disposal of pollutants are low of conducting heat, combined multistage again and burn design concept, is a kind of medical refuse burning technology of clean and effective.
For achieving the above object, the technical solution of the utility model is: a kind of multiple stage fluidized-bed medical refuse burning boiler, it comprises fluid bed and afterburner, fluid bed inside is variable cross-section, fluid bed inside is divided into emulsion zone, transition region and dilute-phase zone from the bottom to top, and being provided with feed hopper, air port and slag dropping tube, fluid bed top communicates with afterburner by reversal chamber.The top of the dilute-phase zone of fluid bed is provided with auxiliary burner, the secondary air mouth is arranged on the top of fluid bed charging aperture, top at dilute-phase zone is provided with tertiary air orifice, and afterburner links to each other with waste heat boiler by the flying dust separation chamber, arranges energy-saving appliance and air preheater in the back-end ductwork of waste heat boiler.
The utility model is owing to adopt said structure, can clean medical waste and burn and in burning process, reclaim the heat energy of containing in medical waste, owing to adopted variable cross-section fluidized-bed structure, sectional combustion technology simultaneously and be provided with auxiliary burner, make the firing efficiency height of medical waste, disposal of pollutants is low in the burning process.According to containing a lot of high heating value components in the medical waste, as the characteristics of plastics, gauze etc., the utility model can reclaim heat energy in burning process, reduced the disposal cost of medical waste in addition.
Description of drawings: Fig. 1 is the structural representation of this device.
The specific embodiment: the specific embodiment of the present utility model is described further: a kind of multiple stage fluidized-bed medical refuse burning boiler below in conjunction with accompanying drawing, it comprises feed hopper 7, slag dropping tube 1, bellows 2, air distribution plate 3, emulsion zone 4, transition zone 5, overfiren air port 6, dilute-phase zone 8, auxiliary burner 10, tertiary air orifice 9, reversal chamber 11, afterburner 12, flying dust separation chamber 16, waste heat boiler 13 and air preheater 15, feed hopper 7 links to each other with the bottom of body of heater dilute-phase zone 8, emulsion zone 4 links to each other with the transition zone 5 of dilute-phase zone 8 by the cross section gradual change, the secondary air mouth is arranged on top at charging aperture, before section of burner hearth hour can adopt, back wall (or both walls) is with two air inlets of the mode of liquidating, section of burner hearth can adopt by the quadrangle tangential circle mode when big and arrange four air inlets, be provided with the tertiary air orifice 9 that auxiliary burner 10 and afterburning are used on the top of dilute-phase zone, dilute-phase zone links to each other with afterburner 12 by reversal chamber 11, afterburner then links to each other with waste heat boiler 13 by flying dust separation chamber 16, arranges energy-saving appliance 14 and air preheater 15 in the back-end ductwork of waste heat boiler.
Medical waste enters fluid bed emulsion zone 4 by feed hopper 7 and mixes with the bed material, a wind is through air preheater 15, bellows 2, air distribution plate 3 enters fluid bed emulsion zone 4, because bed material temperature maintains 780 ℃ ~ 900 ℃ all the time when operation, and the stoichiometric ratio of the quantity delivered of a wind during less than medical waste completing combustion, what therefore medical waste was carried out in fluid bed emulsion zone 4 is pyrolysis, gasification and combustion reaction, wherein the heat of combustion reaction release is used to provide the preheating of medical waste, pyrolysis, the heat that gasification reaction is required is also kept bed temperature, not flammable composition in the medical waste and burning bottom ash discharge out of the furnace through scum pipe 1, contain a certain amount of combustible component in the imperfect combustion volatile products of fluid bed emulsion zone 4, enter dilute-phase zone 8 through changeover portion 5, mixed combustion is continued with the air that is entered by overfiren air port 6 in bottom at dilute-phase zone 8, a spot of tertiary air is entered in the burner hearth by the top tertiary air orifice 9 of dilute-phase zone 8, small amount of solid imperfect combustion composition in the flying dust and gas imperfect combustion composition enter afterburner 12 with the elevated temperature heat flue gas through reversal chamber 11 and further burn, flue gas after burning enters preboiler 13 through the flying dust separation chamber, through the energy-saving appliance 14 and the air preheater 15 of back-end ductwork, enter flue gas purifying equipment and purify the back discharging.For guaranteeing the ignition temperature of dilute-phase zone 8 tops, reversal chamber 11 and afterburner 12, particularly big at a heater stage and the fluctuation of medical waste component, calorific value descends more for a long time, be provided with auxiliary burner 10 on dilute-phase zone 8 tops, when the ignition temperature of afterburner 12 is lower than 900 ℃, burner 9 starts, when the ignition temperature of afterburner 12 was higher than 950C, burner 10 cut out.
The multistage incineration technology that the utility model adopts, and the bigger Cross section Design of the setting of afterburner 12, dilute-phase zone 8, the setting of auxiliary burner 9, guaranteed the medical waste volatile ingredient greater than following time of staying of environment of 900 ℃ greater than 2 seconds, thereby guarantee efficiency of combustion and reduced the discharging of pollutant (as PCDD/F).
