Abstract
The invention discloses a waste gas processing and recycling device of a decorating firing kiln, which comprises a kiln, wherein a muffle board is arranged inside the kiln, the kiln comprises a smoke exhaust area, a preheat area, a firing area and a cooling area, a nozzle is arranged inside the firing area, the smoke exhaust area is arranged in a stained paper waste gas production area on the front end of the kiln, the lower end of the smoke exhaust area is provided with a plurality of smoke exhaust outlets, the upper end of the smoke exhaust area is provided with a plurality of waste gas discharging outlets, and the smoke of the smoke exhaust outlets is exhausted through a smoke exhaust pipeline after being concentrated; waste gas of the waste gas exhaust outlets enters a waste gas exhaust pipeline and then enters the nozzle of the firing area through a combustion-supporting fan after being concentrated; on the premise of guaranteeing the firing quality of the kiln, a dehumidifying structure and the waste gas exhaust structure of the kiln are separated, the waste gas is pumped into the combustion-supporting fan to be conveyed into the kiln so as to be burned; the waste exhaust odor can be eliminated, and environmental protection can be achieved; and the temperature of the recycled exhausted waste gas is about 130 DEG C which is 100 DEG C higher than the normal temperature, so that the energy can be saved, the cost can be reduced, and economy can be achieved.
Description
Technical field:
The present invention relates to a kind of decorating firing kiln, relate in particular to a kind of firing temperature in the exhaust-gas treatment of 1000 ℃ of its decorating firing kilns of decoration firing product and utilization technology once more.
Background technology
Under porcelain industry develop rapidly in modern age, daily life has been enriched in the variation of pottery and glass product.Along with growth in the living standard, material requisite promotes day by day, and underglaze colour flower and Jinsui River glaze flower prod obtain pursuing of high salary crowd, once for the moment is rich and honour symbol.Because its manufacture craft is fastidious, can produce volatile matter in the warm-up phase marble paper, comprise moisture content, oil stain, marble paper carbide etc.; Be because the thin film marble paper on the glaze produces in sintering procedure; Oil stain in the marble paper, moisture content need be excluded, and the burnt gas that the carbonization of marble paper plastic sheeting produces when burning contains SO2, NOx and flue dust etc., can become foul smell; Environmental pollution is serious; Often there is the resident to make trouble outside indivedual decoration firing factories, require enterprise to change environment or stopping production, and decoration firing factory also causes very big loss thus to factory; Simultaneously,, wherein also have oil stain, carbide etc. combustion-supportingly to burn, just wasted after directly discharging because the EGT of discharging is higher, neither environmental protection, also uneconomical.
Summary of the invention
The exhaust-gas treatment and the recycle device that the objective of the invention is to overcome the deficiency of prior art and a kind of decorating firing kiln is provided; The hydrofuge and the waste discharge gas of kiln are carried out separate structure; Waste discharge gas relended to help to be transported in the kiln in the combustion fan burn; Can either prevent that foul smell directly is discharged into contaminated environment in the air, recyclable again useful part, the economy of utilizing.
For realizing above-mentioned purpose, the present invention has adopted following technical proposals:
The exhaust-gas treatment of this decorating firing kiln and recycle device comprise kiln, are provided with flame shield in the kiln; Kiln includes smoke evacuation district, preheating zone, firing zone and cooling zone; Be provided with burner at firing zone, the marble paper waste gas that the smoke evacuation district is arranged at the kiln front end produces the district, is provided with some smoke evacuation outlets in lower end, smoke evacuation district; The upper end is provided with some waste discharge outlets, discharges through the flue gas emptying pipe behind the fume centralized of smoke evacuation outlet; The waste gas of waste discharge outlet is concentrated and is gone into the waste discharge pipeline gets into firing zone again through combustion fan burner afterwards.
Described smoke evacuation outlet is provided with three, the equidistance setting.
Described waste discharge outlet is provided with three, the equidistance setting.
Described smoke discharging pipe is the high-altitude chimney.
Be provided with the adjusting butterfly valve in the described flue gas emptying pipe, reach with control waste gas discharge capacity and respectively account for a temperature.
Be provided with the adjusting butterfly valve in the described waste discharge pipeline, reach with control waste gas discharge capacity and respectively account for a temperature.
Through technique scheme, thereby this invention has following beneficial effect:
Guaranteeing that kiln burns till under the prerequisite of quality, invention is carried out separate structure with the hydrofuge and the waste discharge gas of kiln, waste discharge gas is beaten to help to be transported in the kiln in the blower fan again burn; Eliminate the waste discharge foul smell, environmental protection; The gas of the waste discharge of reclaiming simultaneously itself just has about 130 ℃, and is higher about 100 ℃ than normal temperature, can save the energy, reduces cost, economy.

Specific embodiments
Below in conjunction with accompanying drawing further explanation is made in this invention.
To shown in Figure 4, the exhaust-gas treatment of this decorating firing kiln and recycle device comprise kiln 1 like Fig. 1; Be provided with flame shield 2 in the kiln, kiln includes smoke evacuation district 3, preheating zone 4; Firing zone 5 and cooling zone 6 are provided with burner 7 at firing zone, and the marble paper waste gas that smoke evacuation district 8 is arranged at the kiln front end produces the district; Be provided with some smoke evacuation outlets 9 in lower end, smoke evacuation district, the upper end is provided with some waste discharge outlets 10, discharges through flue gas emptying pipe 11 behind the fume centralized of smoke evacuation outlet; The waste gas of waste discharge outlet is concentrated and is gone into waste discharge pipeline 12 gets into firing zones again through combustion fan 13 burner afterwards; Specifically, described smoke evacuation outlet is provided with three, the equidistance setting; Described waste discharge outlet is provided with three, the equidistance setting; Described smoke discharging pipe is the high-altitude chimney; In described flue gas emptying pipe, be provided with in addition and regulate butterfly valve 14, reach with control waste gas discharge capacity and respectively account for a temperature; In described waste discharge pipeline, be provided with equally and regulate butterfly valve 14, reach with control waste gas discharge capacity and respectively account for a temperature.
Compared with prior art, guaranteeing that kiln burns till under the prerequisite of quality, invention is carried out separate structure with the hydrofuge and the waste discharge gas of kiln, waste discharge gas is beaten to help to be transported in the kiln in the blower fan again burn; Eliminate the waste discharge foul smell, environmental protection; The gas of the waste discharge of reclaiming simultaneously itself just has about 130 ℃, and is higher about 100 ℃ than normal temperature, can save the energy, reduces cost, economy.
