Abstract

The present invention relates to a method for incinerating medical waste and a special device. The present invention has the problem to be solved that intermittent charging existing in the background art has the defects of air pollution, secondary fuel oil pollution, high manufacture and running cost and long exposed time. The present invention has the technical scheme for solving the problem that a disposable charging mode is adopted to make medical waste combusted and decomposed through at least two smoke elimination chambers with coke burning reactors after the medical waste passes through the main combustion, the secondary combustion and the third-time combustion of a main combustion furnace; then the medical waste enters a water cooler to be cooled and is processed by a secondary cyclone wet dust collector; finally, the medical waste is discharged from a chimney. The used special device is the main combustion furnace composed of a main combustion chamber, a secondary combustion chamber and a third-time combustion chamber which are communicated, wherein the third-time combustion chamber is connected with a disposable smoke elimination chamber and a secondary smoke elimination chamber through flues, and the disposable smoke elimination chamber and the secondary smoke elimination chamber are connected in series. The secondary smoke elimination chamber is then orderly connected with the water chiller and the secondary cyclone wet dust collector through flues. The present invention can be used for incinerating medical waste, and has the notable advantages of less pollution and low manufacture and running cost.

Description

The method that a kind of Biohazard Waste is burned

Technical field: the present invention relates to the method that a kind of Biohazard Waste is burned, particularly a kind of method that is suitable for the Biohazard Waste innoxious burning.

Background technology: clinical waste is a kind of special solid waste fuel, and combustible wherein is based on plastics, rubber.Have big, the characteristics rapidly of burning of caloric value.The method of the medical wastes incineration that uses is to adopt step feeding mode toward the chamber of the combustion again burning that main chamber feeds intake and makes its burning, the flue gas that is produced enter fuel oil more at present, the processing of live at last capable carbon absorption and bag-type dust.The basic structure of the medical wastes incineration stove that is used with it is that the main chamber that has fire grate connects the chamber of combustion again that has oil burning installation, fires the chamber again and connects absorbent charcoal adsorber and sack cleaner.The incinerating method of this structure adopts intermittent feeding at work.After dropping into clinical waste toward main chamber, cause combustibles deflagrations such as plastics, rubber to cause stove cigarette effusion contaminated air, the dioxin in the stove cigarette must at high temperature could decompose, the serious harm health of human body; Improve the temperature of firing the chamber again for pollution abatement need rely on a large amount of diesel oil of burning, increased fuel oil pollution so again and increased the burning cost; Inadequate like this combustion efficiency makes the combustible component in the tail gas increase, and causes the exhaust gas processing device complexity, easily stops up, and maintenance rate is high, needs to increase the power of air-introduced machine, has increased manufacturing and operating cost; Thisly on the other hand steply feed intake that to make that clinical waste exposes the time long, cause bacterium, viral pollution environment in the clinical waste easily, the harm health of human body.

Summary of the invention: technical problem to be solved by this invention is exactly that the batch (-type) that exists of background technology feeds intake that contaminated air, fuel oil pollute once more, manufacturing and operating cost height, the time of exposing are long.Solving this technical problem the technical scheme that is adopted is: a kind of method of medical wastes incineration and special equipment thereof, adopt disposable feeding mode, after making main burning, second-time burning and three burnings of medical waste through main burning furnace, decompose by at least 2 smoke elimination chamber high-temp combustions that have the char combustion heap again, enter the water cooler cooling again, handle last again by secondary whirlwind hydrofilter through smoke stack emission.It is characterized in that this method implements in following equipment: feeding vehicle matches with the main combustion chamber that has fire door, main combustion chamber fire grate and air blast, the chimney that the end of combination stove is provided with air-introduced machine and is attached thereto, main burning furnace is made up of the dual firing chamber on the main combustion chamber that communicates, top and three combustion chambers of both sides thereof, three combustion chambers by flue with series connection and have clearly that the once smoke elimination chamber of smoke-box fire grate is connected with secondary smoke elimination chamber, the indoor char combustion heap that respectively is provided with of first and second smoke elimination, secondary smoke elimination chamber is connected with secondary whirlwind hydrofilter with water cooler successively by flue again.Set-point ignition combustor in the main combustion chamber wherein.The beneficial effect that the present invention and background technology comparison are had is: owing to adopt technique scheme, feeding vehicle is the disposable input main chamber of clinical waste, light refuse after closing fire door, main chamber quick heating like this, make clinical waste burn from top to bottom, can control its burning velocity, avoid deflagration and make stove cigarette effusion contaminated environment, the environmental pollution of having avoided batch (-type) to feed intake and brought simultaneously; On the other hand, utilize the char combustion heap to produce high temperature in two smoke elimination chambers that increased, effectively decomposed pernicious gases such as dioxin; The tail gas that is produced through burning does not on the one hand almost have fuel gas again, and has overcome fuel oil pollution, has omitted devices such as charcoal absorption, greatly reduces to make and operation cost.

Description of drawings: Fig. 1 is the overall structure schematic diagram of special equipment of the present invention; Fig. 2 is the K-K profile of Fig. 1; Fig. 3 is the process chart of the inventive method.

The specific embodiment: with reference to figure 3, a kind of method of medical wastes incineration and special equipment thereof, this method adopts disposable feeding mode, after making main burning, second-time burning and three burnings of clinical waste through main burning furnace, decompose by at least 2 smoke elimination chamber high-temp combustions that have the char combustion heap again, enter the water cooler cooling again, handle last again by secondary whirlwind hydrofilter through smoke stack emission.With reference to figure 1, Fig. 2, a kind of special equipment that uses said method, feeding vehicle 1 matches with the main burning furnace 3 that has fire door 2, main combustion chamber fire grate 11 and air blast 13, the chimney 17 that the end of combination stove is provided with air-introduced machine 16 and is attached thereto, main burning furnace 3 is made up of the dual firing chamber 19 on the main combustion chamber 18 that communicates, top and three combustion chambers 4 of both sides thereof.Three combustion chambers 4 are connected with secondary smoke elimination chamber 8 with the once smoke elimination chamber 7 of connecting and have a smoke elimination chamber fire grate 14 by flue 6, the indoor char combustion heap 15 that respectively is provided with of first and second smoke elimination, secondary smoke elimination chamber 8 is connected with secondary whirlwind hydrofilter 10 with water cooler 9 successively by flue again, set-point ignition combustor 5 in the main combustion chamber 18, disposable input clinical waste 12 in the stove.
