Description
Technical field：The present invention relates to a kind of cooking stove for burning away the refuse, particularly a kind of improved innoxious rubbish
Incinerator.
Background technology：Before the application, the applicant has submitted a entitled " innoxious waste incinerator " its patent
Number be " 201620802372.0 " patent application.Although the patented product has larger strong point in use, there is also one
A little problems：1st, burning be obstructed, be obstructed, influence efficiency of combustion, this is essentially consisted in, exhaust gas row mouth be located at furnace body bottom namely
Main fire grate is easily blocked after falling in the bottom of fire grate, in operation, the ashes generated by upper strata pair fire grate combustion refuse, from
And cause entire furnace body air-flow constricted flow, it smooth cannot go downwards to after-flame layer in the fuel gas that carbonization gasification layer generates
Active combustion is carried out, so as to still there is uncombusted gas discharge；2nd, fresh air supply is improper, because air inlet is located at main stove
The upper space of row, 3, cycle channel it is few, an and only outer circulation has thermal losses and is unfavorable for the collection of tar.
Invention content：It is an object of the present invention to for existing " innoxious waste incinerator " it is existing in use on
It states deficiency, and proposes a kind of improved innoxious waste incinerator, it has a better combustion efficiency, unburned in the exhaust gas of discharge
Most gas further reduces, and environment protecting is also more preferable.
Can realize the object of the invention by following technical proposals, a kind of improved innoxious waste incinerator, including furnace body,
Furnace top cover, fire grate, secondary fire grate, burner hearth, fire door, feed inlet, cycle smoke pipe, flue gas cleaner, frequency conversion fan, wind turbine, feature
It is, further includes flue, tar collecting pipe, tar collecting pit, furnace body inner circulating tube；Feed inlet is located on furnace top cover, furnace body top
End is equipped with annular water tank, and the Zhou Bianduan of furnace top cover is inserted in annular water tank, and fire grate and secondary fire grate are all located under furnace body inner cavity
Portion, secondary fire grate are located above fire grate, and are designed with burner hearth above fire grate and secondary fire grate, opening of the flue in furnace body inner cavity is located at stove
Between row and secondary fire grate, tar collecting pipe one end is connect with upper of furnace body inner cavity, and the other end is connect with tar collecting pit, 2 with
On furnace body inner circulating tube be located in the side wall of furnace body, one end open is located at the inner cavity of upper of furnace body, and another end opening is located at pair
Furnace body inner cavity between fire grate and fire grate, the air inlet of wind turbine are located at the sidewall of the furnace body below fire grate, recycle smoke pipe one end and stove
The inner cavity connection on body top, the other end are inserted in flue gas cleaner, and frequency conversion fan is connected by the side wall of pipeline one end and burner hearth,
The other end is connect with flue gas cleaner, and fire door is located at sidewall of the furnace body.
To improve combustion efficiency, burner hearth is made of interlayer, and the inner wall of burner hearth is equipped with through-hole, and through-hole presses ring
Shape layering is evenly arranged.
Effect of the invention is that：1st, combustion efficiency further improves；This is, stove body-internal-circulation is additionally arranged in the present apparatus
Pipe, most of gas in furnace body after burning constantly return to the burner hearth between fire grate and secondary fire grate by furnace body inner circulating tube
Middle burning, because being interior cycle, many tar and combustible are further returned in burner hearth to burn (in the prior art then from flue gas again
Clarifier eliminates), so as to greatly improve efficiency of combustion；In addition, the flue in the present apparatus is moved by being located at bottom of furnace body originally
The top of the cavity namely stove gate between fire grate and secondary fire grate has been arrived, this causes the air-flow of burning to become unobstructed, because, as long as
Fire door is shut, flue can generate a very big draft, the fuel gas of burning zone and upper space can be made to go downwards to after-flame
Layer is more fully burnt, so as to improve combustion efficiency；2nd, environment protecting further improves, and can reach and is externally arranged without exhaust gas
It puts, the present apparatus makes furnace structure more reasonable after the prior art is transformed, and furnace body inner cavity is effectively divided into drying by it
Layer, carbonization gasification layer, burning zone, after-flame layer, and make the repeatedly burning and residence time is long repeatedly of the gas circulation of inner cavity,
So that wherein environmentally harmful carbon monoxide, hydrogen, methane and severe toxicity bioxin etc. can be removed fully, so as to
Environment protecting is further improved, reaches external non-exhaust emission；3rd, fuel is saved, the present apparatus is in addition to being initially required some fuel
Device is made to enter normal operation for refuse gasification, be no longer needed for external fuel thereafter, because the present apparatus has very high burning
Efficiency, all organic matters in rubbish can gasify by it and fully complete burning, these thermal energy maintain device enough
Normal operation, so as to save many fuel.
Description of the drawings：
Accompanying drawing 1 is the structural representation of the present invention；
Attached drawing 2 is the sectional view at attached drawing 1A~A.
The present invention is expanded on further with reference to the accompanying drawings and embodiments：
Specific embodiment：
