Organic waste gas that curing oven produced in cotton production of glass gets rid of technology structure add a combustion chamber be furnished with the combustor in, before the water smoke absorption tower, waste gas is collected after the combustor burns, get rid of the organic waste gas who produces in the curing oven is whole, then through the water smoke absorption tower once more the row of purification to the atmosphere in. Can retrieve the heat that burner produced during this time, send into again during curing oven etc. Needs the equipment of high temperature, make the heat obtain cyclic utilization, reach energy -concerving and environment -protective, cost -effective purpose.
Description
Technical field
The utility model relates to industrial organic exhaust gas discharge field, particularly relates to the voc_s removal technical construction that in the production of a kind of mineral wool, curing oven produces.
Background technology
Mineral wool the glass centrifugal blast technique being in molten condition is carried out the filamentary material made of fibrillatable spraying thermosetting resin, then through heat cure deep processing process, can be made into the series of products served many purposes.It has the plurality of advantages such as fire-retardant, nontoxic, corrosion-resistant, unit weight is little, thermal conductivity factor is low, chemical stability is strong, hydroscopicity is low, hydrophobicity is good, be the best performance of generally acknowledging at present get over insulation, heat insulation, sound-absorbing material, there is purposes very widely.The plate made with this material, felt, pipe a large amount of for building, chemical industry, electronics, electric power, metallurgy, the energy, the insulation in the field such as traffic, sqouynd absorption lowering noise, effect is very remarkable.
The production technology of mineral wool product is mainly divided into storing-batch mixing-fusing-fibroblast-collection cotton-solidification-cooling-trimming-pack-put in storage several part.Wherein, need in process of production to add the auxiliary agent such as adhesive phenolic resin and organosilicon moisture repellent, ammoniacal liquor, urea, thiamines, by curing oven at about 200 DEG C curing moldings.But due to the use of phenolic resins and other auxiliary agents, in curing molding process, discharge the organic exhaust gas such as a certain amount of free phenol, free aldehyde, nitrogen oxide, aniline, after cyclone dust collectors, the process of water smoke absorption tower by smoke stack emission in air.Because current this treatment process can not process the organic exhaust gas of curing oven generation effectively, the organic exhaust gas be discharged in air is exceeded standard and obviously with certain color, causes environmental protection tests defective.
At present, in mineral wool production process, gas mainly first removes after particle through cyclone dust removal by the process of the organic exhaust gas that curing oven produces, then through water smoke absorption tower out, is discharged in air by the pipeline of about 30 meters.Such treatment effect is poor, and operating cost is higher, and chimney place has significantly band color waste gas to discharge, and environmental protection is not up to standard, affects the normal production of mineral wool manufacturer, affects atmospheric environment yet.
Summary of the invention
The purpose of this utility model is exactly the technical construction that will propose the voc_s removal that curing oven produces in a kind of mineral wool production process, this structure is before water smoke absorption tower, set up a combustion chamber, inside is furnished with burner, burn through burner after gas sampling, the organic exhaust gas produced in curing oven is all removed, is then again purified by water smoke absorption tower and be discharged in air.Period can reclaim the heat that burner combustion produces, and again sending into curing oven etc. needs in the equipment of high temperature, heat is recycled, reaches energy-conserving and environment-protective, cost-saving object.
The object of the invention is to be achieved through the following technical solutions:
The voc_s removal technical construction that in mineral wool production, curing oven produces, described structure comprises mineral wool production line curing oven, production line front end flue, production line end flue, combustion chamber, heat recovery pipeline, air-supply arrangement, gas fume valve, water smoke absorption tower; Described mineral wool production line curing oven two ends are connected to production line front end flue and production line end flue respectively, combustion chamber is connected to after described production line front end flue and production line end flue collect, the exit of described combustion chamber is provided with gas fume valve, and the other end of gas fume valve connects water smoke absorption tower; Be provided with heat recovery pipeline between described combustion chamber and gas fume valve, connect air-supply arrangement by described heat recovery pipeline, the other end of described air-supply arrangement is connected to again mineral wool production line curing oven.
Further, described mineral wool production line curing oven comprises again upper link plate and lower carrier bar.
beneficial effect compared to existing technology described in the utility model is:
1, the voc_s removal technical construction that in mineral wool production described in the utility model, curing oven produces, can be widely used in block of glass wool production line, the organic exhaust gas produced in mineral wool production process can be removed, can recycle heat simultaneously, reach energy-conserving and environment-protective, cost-saving object;
2, the voc_s removal technical construction that in being produced by mineral wool described in the utility model, curing oven produces, discharges without obvious colored flue gas in the tail gas of generation, meets environmental protection tests requirement.

Detailed description of the invention
Embodiment 1
The structure realizing the voc_s removal technical construction that curing oven produces in mineral wool of the present utility model production is: mineral wool production line curing oven 1 comprises upper link plate and lower carrier bar, glass cotton strip after collection cotton is constantly travelled forward in production line by the conveying of upper and lower carrier bar, period will through 4 sections of solidifications, 1 stage solidification respectively, 2 stage solidification, 3 stage solidification, 4 stage solidification, each cure stage in-furnace temperature is 180 DEG C-200 DEG C, hot gas is through recycling back in curing oven after the glass cotton strip on production line, curing agent phenolic resins is thermoset articles, glass cotton strip curing molding can be made through after glass cotton strip under 200 DEG C of environment, complete the program curing of mineral wool product.Phenolic resins can produce containing certain organic flue gas after heated, flue gas collects respectively by production line leading portion flue 2 and end flue 3, arrive in combustion chamber 4, burner is provided with in combustion chamber 4, burner temperature can up to 800 DEG C-1000 DEG C, can decompose after combustion chambers burn containing organic flue gas, thus remove the organic matter in flue gas.Gas fume valve 7 is provided with in the exit of combustion chamber, can be transmitted back in curing oven by heat recovery pipeline 5 when the flue gas pressures after purifying is less, air-supply arrangement 6 mainly plays the effect of conveying fresh air, fresh air and gas out in burner reach the temperature that curing oven is suitable for after mixing, and are delivered in curing oven; When the flue gas pressures after purifying is larger, gas fume valve 7 can be opened automatically, is discharged in air after the flue gas after part purification can be purified again by water smoke absorption tower 8.
