Abstract
The utility model discloses a vertical hot blast stove, which comprises a stove body. The stove body is internally provided with a hearth, which is provided with a stove door communicated with the hearth at the lower section and a plurality of guide pipes at upper section; the guide pipes extend out from the stove body and form a plurality rows of guide pipes at upper section of the hearth with each row composed of a plurality of guide pipes. The utility model has he advantages of simple structure, capable of removing soot and enhancing burning rate and fuel-saving.
Description
Technical field
The utility model relates to a kind of timber dryer, especially a kind of vertical hot furnace.
Background technology
China's drying of wood is mainly based on hot blast, and major part is used hot-blast stove, and the fuel that hot-blast stove adopts is timber such as wood chip and wood shavings, and the characteristics of timber are that the volatilization composition is many, phosphorus content is high, so the demand of air is far longer than common bituminous coal.The present general hot-blast stove that uses, comprise body of heater, body of heater inside has burner hearth, the body of heater bottom is provided with the air guide hole that communicates with burner hearth, the hot-blast stove of this structure is given the mode of wind below body of heater the time is all adopted in burning, for vertical hot furnace, upper furnace is best place and the best opportunity that fly ash combustible material and volatilization composition burn away, and can't continue to supply with sufficient air to upper furnace for below the body of heater wind, fly ash combustible material and volatilization composition are burnt, therefore, formed the over-emitting black exhaust phenomenon, the dust concentration height of not only discharging fume, and caused waste of fuel.The method of common smoke abatement and dust control is that the exhaust opening in the body of heater upper end adds deduster, and so not only manufacturing cost height, and operating cost is also high.
The utility model content
The purpose of this utility model is to address the aforementioned drawbacks and a kind of several guide ducts in upper furnace setting and body of heater exterior is provided, and has simple in structure, smoke abatement and dust control, raising combustion rate, fuel-saving vertical hot furnace.
Technology solution of the present utility model is as follows:
A kind of vertical hot furnace comprises body of heater, and body of heater inside has burner hearth, and the body of heater bottom is provided with the fire door that communicates with burner hearth, and upper furnace is provided with several guide ducts, and guide duct stretches out outside the body of heater.
The utility model can also adopt following technical measures to solve:
Described several guide ducts form the plurality of rows guide duct that is arranged above and below in upper furnace, and every row is made up of a plurality of guide ducts.
Guide duct on described every row is on same horizontal plane.
Described plurality of rows guide duct is dislocation and arranges.
Adopt the outstanding effect of said structure vertical hot furnace to be:
1), by the guide duct of several and body of heater exterior is set in upper furnace, utilize the outer air blast of guide duct, provide required oxygen to burner hearth, hot-air promptly is provided, the gas that stirs in the burner hearth makes it to mix, reduce unburnt loss, effectively improve its efficiency of combustion, fuel savings.
2), several guide ducts on the burner hearth form the plurality of rows guide duct, each is arranged guide duct and is the dislocation layout, utilize the plurality of rows guide duct in burner hearth, to form the flue gas vortex, be subjected to the centrifugal action of flue gas vortex, time and stroke that the thin carbon granule that prolongation suspends stops in stove, reduce unburned combustible in fly ash, reach the effect of smoke abatement and dust control.

The specific embodiment
As shown in Figures 1 to 4, a kind of vertical hot furnace comprises body of heater 1, and body of heater 1 inside has burner hearth 2, and body of heater 1 bottom is provided with the fire door 3 that communicates with burner hearth 2, and burner hearth 2 tops are provided with several guide duct 4, and guide duct 4 stretches out outside the body of heater 1.Described several guide duct 4 forms the plurality of rows guide duct be arranged above and below on burner hearth 2 tops, every row is made up of a plurality of guide ducts 4.Guide duct 4 on every row is on same horizontal plane.Wherein, above-mentioned plurality of rows guide duct is the dislocation layout.
Operation principle: fuel is put into burning from fire door 3, many rows guide duct on burner hearth 2 tops is under the effect of air blast, form the multiply air-flow in burner hearth 2 tops, cause the flue gas vortex, utilize the centrifugal action of flue gas vortex, time and stroke that the thin carbon granule that prolongation suspends stops in stove, reduce unburned combustible in fly ash, the hot blast that produces in the burner hearth 2 is discharged from the hot-blast outlet 5 of body of heater 1 bottom, and clean flue gas is discharged from the exhaust opening 6 of body of heater 1 upper end in the burner hearth 2, reaches the effect of smoke abatement and dust control.
