Description
Technical field
The utility model relates to a kind of color-coating line waste gas recovery of latent heat structure be applied in Coil Coating Products production process.
Background technology
In Coil Coating Products production process, heating pre-treatment water and hot-air seasoning paint all need to consume a large amount of heats.Origin of heat is combustion of natural gas mainly, and according to the difference of process equipment, mode of heating has directly heating and indirect two kinds.
The waste gas that combustion of natural gas generates is discharged eventually through chimney, and exhaust gas temperature is generally at about 100 ~ 200 degree.Containing a large amount of steam in combustion of natural gas product, if the steam that every cubic natural gas firing generates all is condensed into liquid water, so steam condensing liberated heat is equivalent to combustion of natural gas exothermic 10%, can save a large amount of gas consumption.For the color-coating line being equipped with RTO system, except the steam that combustion of natural gas generates, also have the steam that various VOC gas combustion generates in waste gas, the heat that can reclaim for condensation is far above general gas boiler.Current various condenser boiler has had a lot of mature technology, but the recovery of the steam condensing of color-coating line there is not yet open report.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of color-coating line waste gas recovery of latent heat structure, exhaust gas temperature can be reduced to 50 ~ 80 degree by 100 ~ 200 degree by it, a large amount of recovery steam condensing liberated heat, thus significantly improve the color-coating line thermal efficiency, natural gas completely can be reduced and consume more than 10%.
The utility model solves the technical scheme that its technical problem adopts:
A kind of color-coating line waste gas recovery of latent heat structure, comprise blower fan, condenser and air converter is provided with above it, surrounding air to condenser through blower fan suction, receives in it and heats up after steam-condensation release heat, then enters in air converter and form hot blast, described air converter sidepiece is provided with curing oven, be provided with incinerator on the downside of described curing oven, hot blast enters in incinerator after curing oven, and described incinerator is communicated to air converter and condenser forms a closed loop waste gas recovery of latent heat structure.
As the improvement of technique scheme, on the downside of described condenser, drainpipe is provided with condensation water tank, on the right side of it, is provided with the chimney for discharging waste gas.
As the improvement of technique scheme, surrounding air is through blower fan suction to condenser, and temperature rises to more than 60 DEG C, then enters in air converter and form hot blast, and its temperature rises to more than 280 DEG C.
As the improvement of technique scheme, be provided with air channel and steel band in described curing oven, hot blast is entered after in curing oven by air channel and heats steel band, and temperature is reduced to 240 DEG C.
As the improvement of technique scheme, be provided with VOC gas in described incinerator, it forms a large amount of steam and waste gas after burning cracking, and waste gas temperature after air converter is reduced to 120 DEG C, enters in condenser subsequently, and temperature is reduced to 60 DEG C of discharges.
The beneficial effect that the utility model brings has:
The utility model has set up condenser before color-coating line waste air, exhaust gas temperature can be reduced to 50 ~ 80 DEG C by existing 100 ~ 200 DEG C, thus effectively utilize the condensation latent heat of steam, a large amount of recovery steam condensing liberated heat, thus significantly improve the color-coating line thermal efficiency, natural gas completely can be reduced and consume more than 10%.
Accompanying drawing explanation
