It is connected on the feed separation and material-returning device of intermediate zone outlet；The feed separation and material-returning device include separator and connection
The separator and the separator inlet flue of the intermediate zone, and material returning device；The burner hearth include being formed it is middle wide,
The lower cone section and upper cone section in upper and lower narrow variable cross-section space；The burner hearth bottom is equipped with blast cap and an air compartment；Air compartment
Cause to be formed in material in the variable cross-section space of the burner hearth with the cloth wind of blast cap and circulate；It is characterized in that：The incinerator is also
Including sand blasting unit, the sand blasting unit is arranged in the burner hearth, and close to the upper cone section；The sand blasting unit includes spray
Sandpipe and several sand jet outlets for being arranged on blast tube；The sand jet outlet is arranged to opening towards the upper cone section.
In above-mentioned technical proposal, the blast tube extending direction is consistent in the extending direction of horizontal plane with the upper cone section,
Along the inclined short transverse of upper cone section, the blast tube can set multiple.
In above-mentioned technical proposal, the upper cone section is arranged symmetrically in the burner hearth, the blast tube and is arranged on sandblasting
Several sand jet outlets of pipe are arranged symmetrically in the burner hearth accordingly, and the sand jet outlet is arranged to opening towards the epicone
Section.
In above-mentioned technical proposal, the blast tube telescopic setting in their extension direction.
The utility model has the following advantages and beneficial effect：The setting of upper lower cone section makes freeze profile into following in material
Ring, plus the outer circulation of separation returning charge, Two-way Cycle make it that material burning is more abundant, primary pollutant is lower；Sand blasting unit is set
Put, burner hearth upper cone section wall is formed and is washed away, avoids sticky ash deposition, while supplement bed material.
Brief description of the drawings
Fig. 1 is a kind of Two-way Cycle turbulent bed incinerator schematic diagram with sand blasting unit involved by the utility model.
In figure：1- burner hearths；2- intermediate zones；3- separators；4- separator inlet flues；5- material returning devices；6-
Blast tube；7- sand jet outlets；Air compartment of 8-；9- blast caps；10- upper cone sections；11- lower cone sections.
Embodiment
Specific embodiment of the present utility model and the course of work are further described below in conjunction with the accompanying drawings.
The orientation such as upper, lower, left, right, front and rear in present specification term be based on position relationship shown in the drawings and
Establish.Attached drawing is different, then corresponding position relationship is also possible to change therewith, therefore cannot be interpreted as with this to protecting model
The restriction enclosed.
As shown in Figure 1, a kind of Two-way Cycle turbulent bed incinerator with sand blasting unit, the incinerator includes burner hearth 1, secondary
Combustion zone 2 and the feed separation and material-returning device for being connected to the outlet of intermediate zone 2.Feed separation and material-returning device include separation
Device 3 and the connection separator 3 and the separator inlet flue 4 of the intermediate zone 2, and material returning device 5.Burner hearth 1 includes
The lower cone section 11 and upper cone section 10 in wide, upper and lower narrow variable cross-section space among being formed, lower cone section 11 form flaring section to external expansion,
And upper cone section 10 forms tapered cross-section to contract.1 bottom of burner hearth is equipped with blast cap 9 and an air compartment 8, and blast cap 9 selects orientation wind
Cap.By an air compartment 8 and the cloth wind of blast cap 9, then coordinate the staged air distribution measure such as secondary air distribution, the variable cross-section space of burner hearth 1
Circulation loop in interior formation material.Rubbish the like waste and biomass form violent turbulence, greatly when fuel burns in burner hearth 1
Improve burnout rates and efficiency of combustion greatly.Part flying dust is with flue gas uplink, and unburnt gas component is in prismatic secondary combustion
Burn in area 2 and further burn completely.Band cloud of dust gas enters separator 3 by separator inlet flue 4 and carries out gas solid separation, separation
Flue gas afterwards carries out follow-up facility, and the flying dust separated returns to burner hearth 1 by material returning device 5, and feed back point is usually in upper cone section 10.
The Matter Transfer of feed separation and material-returning device constitutes the outer circulation circuit of the incinerator.
Since the fuel ash such as rubbish the like waste and biomass are low and are rich in alkali metal, the grey caking property after burning is very
It is high.And upper cone section 10 is due to its section angle with horizontal plane α<90 ° of architectural feature, on interior circulation loop and outer circulation circuit
Flue gas, material, which are all difficult to produce its interior sidewall surface, to be washed away, so that high viscosity ash is easy in 10 interior sidewall surface of upper cone section
Upper deposition.To solve the problems, such as this, the incinerator further includes sand blasting unit, and sand blasting unit is arranged in burner hearth 1, and close to upper
Bore section 10.Sand blasting unit includes blast tube 6 and is arranged on several sand jet outlets 7 of blast tube 6；Several sand jet outlets 7 are all set
One side in blast tube 6 towards upper cone section 10, and sand jet outlet 7 is open towards upper cone section 10.So that be passed through in blast tube 6
Quartz or fine sand can be all ejected on the inner wall of upper cone section 10 by sand jet outlet 7.Due to usually laying refractory material in burner hearth 1
To reach heat-accumulation combustion effect, the soot blowing effect of sandblasting is good and scouring force will not damage wall.
6 extending direction of blast tube is consistent in the extending direction of horizontal plane with upper cone section 10, and blast tube 6 is in their extension direction
Telescopic setting, i.e. blast tube 6 can stretch in boiler depth or width, and elongation is to the upper conical surface 10 as needed
Inner wall carries out sandblasting, retracts again after the completion of sandblasting.Telescopic blast tube 6 may be collapsed to outside burner hearth 1, so as to avoid in burner hearth 1
The damage that high temperature sintering produces it.When 10 depth of upper cone section or longer width, blast tube 6 is in depth or width
On be arranged symmetrically, symmetrically bounce back after sandblasting.It and can set multiple along 10 inclined short transverse of upper cone section, blast tube 6.
Upper cone section 10 is to be arranged symmetrically, therefore, blast tube 6 and several sand jet outlets for being arranged on blast tube 6 in burner hearth 1
7 are also arranged symmetrically in burner hearth 1 accordingly, and sand jet outlet 7 is arranged to opening towards upper cone section 10.If blast tube 6 sets more
It is a, also it is arranged symmetrically accordingly multiple.
6 external connection of blast tube sandblasting charging gear.
Sandblasting in burner hearth 1, may also reach up the purpose of supplement bed material.
