Abstract

The utility model relates to a medical waste combined incinerator, aiming at solving the technical problems of air pollution, fuel oil re-pollution, high manufacture and operation cost and long exposure time in the background techniques. The technical proposal for solving the problems is characterized in that: a main burner comprises a main combustion chamber, a secondary combustion chamber and a third combustion chamber which are communicated with each other; wherein, the third combustion chamber is connected with an once-and-for-all smoke eliminating chamber and an twice smoke eliminating chamber through a smoke flue; the once-and-for-all smoke eliminating chamber is provided with a smoke cleaning chamber grate bar and is connected in series with the twice smoke eliminating chamber, and a coke burning heap is arranged in either chamber; the twice smoke eliminating chamber is connected in sequence with a water cooler and a secondary cyclone wet dust collector. The utility model can be used for medical waste incineration and has the notable advantages of less pollution, low manufacture and operation cost.

Description

A kind of medical wastes incineration combination stove

Technical field: the utility model relates to a kind of incinerator, particularly a kind of burning combination stove that is suitable for the clinical 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 basic structure of the medical wastes incineration stove that uses is that the main chamber that has fire grate connects the chamber of combustion again that has oil burning installation at present, fires the chamber again and connects absorbent charcoal adsorber and sack cleaner.The incinerator 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 the stove cigarette to be overflowed and contaminated air, the dioxin in the stove cigarette must at high temperature could decompose, the serious harm health of human body; Fire the temperature of chamber again for pollution abatement need rely on a large amount of diesel oil raisings of burning, increased fuel oil pollution so again and increased the burning cost; Inadequate combustion efficiency like this 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, thereby has increased manufacturing and operating cost; Also on the one hand, thisly steply feed intake that to make that clinical waste exposes the time long, cause bacterium, viral pollution environment in the clinical waste easily, endanger health of human body.

Summary of the invention: technical problem to be solved in the utility model is exactly that the background technology contaminated air, the fuel oil that exist 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 medical waste is burned combination stove, feeding vehicle with have a fire door, the main burning furnace of main combustion chamber fire grate and air blast matches, the chimney that the end of combination stove is provided with air-introduced machine and is attached thereto, it is characterized in that main burning furnace is by the main combustion chamber that communicates, three combustion chambers of the dual firing chamber on top and both sides thereof are formed, 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, one, the indoor coke heap that respectively is provided with of secondary 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 utility model 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, decomposed pernicious gases such as dioxin effectively; 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 an overall structure schematic diagram of the present utility model; Fig. 2 is the K-K cutaway view of Fig. 1.

The specific embodiment: with reference to figure 1, Fig. 2, a kind of medical waste is burned combination stove, feeding vehicle 1 with have fire door 2, the main burning furnace 3 of main combustion chamber fire grate 11 and air blast 13 matches, the chimney 17 that the end of combination stove is provided with air-introduced machine 16 and is attached thereto, main chamber 3 is by the main combustion chamber 18 that communicates, three combustion chambers 4 of the dual firing chamber 19 on top and both sides thereof are formed, 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, one, the indoor coke heap 15 that respectively is provided with of secondary 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 medical waste 12 in the stove.
