Description
Technical field
The present invention relates to brick and tile baking equipment, be specifically related to a kind of mobile tunnel furnace baking flue gas processing equipment, utilize this equipment can effectively process the poisonous SO in baking flue gas2, reduce the pollution to environment.
Background technology
Mobile tunnel furnace is a kind of fired brick roasting kiln of the newest in recent years, and it has a lot of advantageous advantage compared with traditional annular kiln and tunnel cave.But, govern always the bottleneck problem of its development be exactly cigarette vapour process the water vapour that produces after problem, specially waste gas and brick bat drying focus on problem.
There is two ways in the market to process cigarette vapour: mode one, by the most any process of cigarette vapour, be directly discharged in air.The maximum benefit of this mode is exactly that the discharge of cigarette vapour need not change the pressure balance within kiln and realizes, and does not affect the roasting of brick.Although the most this mode is simple, but not environmentally, do not meet the policy of country.Mode two, by branch air duct, the cigarette vapour of generation is collected in main air duct, be then sent through desulfurizing tower and carry out desulfurization process.Its principle is through the draft of blower fan and all main air ducts, branch air duct is formed negative pressure, and waste vapour is collected.This just have impact on the pressure balance of whole kiln, and the roasting on brick creates the biggest impact.In brief: humidity discharging, desulfurization to process the firing pressure instability that will make whole kiln, thus affect roasting, finally affect the quality of goods.It is thus desirable to provide a kind of i.e. possess humidity discharging, desulfurization again possess ensure baked article quality the technical scheme made the best of both worlds.And the desulphurizing ability of existing desulfurizer has much room for improvement.
Summary of the invention
The present invention overcomes the deficiency of background technology to provide mobile tunnel furnace baking flue gas processing equipment, and the purpose of design is, it is ensured that carry out humidity discharging on the premise of the quality of fire refractory brick goods, the desulfurization of the useless cigarette of sintering processes, and significant desulfurization effect improves.
The invention provides following technical proposals: mobile tunnel furnace baking flue gas processing equipment, the smoke exhaust pipe that is connected with described kiln including kiln, desulfurizer, described desulfurizer contains flue, the desulfurizing tower that the storage smoke duct that is connected with described storage barn of barn is connected with described smoke duct, described flue is connected to one end of transition conduit, the other end of described transition conduit is connected with the air inlet of described desulfurizing tower, and the gas outlet of described desulfurizing tower connects chimney.
Further, the ceiling of described storage barn is arch, and described storage barn is provided with tank, and four walls of flue are provided with water cavity, and described tank connects with described water cavity.
Further, described kiln is annular tunnel kiln, and described flue is annular, and described flue is fixing with described kiln to be connected.
Further, described storage barn is provided with the storage barn air exhauster of three, and described smoke duct is provided with smoke exhaust fan.
Further, the inwall of described desulfurizing tower is provided with spray nozzle, and the injection of described spray nozzle is dissolved with NaOH, CaCO3Solution.
Beneficial effects of the present invention: this technology is by setting up a sealing device at kiln crown, stores up barn 3.By all fume centralizeds emitted inside, by blower fan, flue gas is delivered in desulfurizing tower the most again.This storage barn 3 is equivalent to simulate a natural space, and the pressure of the inside is equilibrium, is equivalent to the discharge naturally of mode one in background technology.It does not interferes with the pressure balance within kiln, thus does not affect the quality of end article.
The ceiling of described storage barn 3 is arch, and described storage barn 3 is provided with tank 8, and four walls of flue 5 are provided with water cavity 9, and described tank 8 connects with described water cavity 9.The globule that sintering produces is collected to tank 8 by this design cleverly, then by the water body in tank 8 by, in tuber drainage to the water cavity 9 of four walls of flue 5, flue being realized water-stop, it is to avoid the leakage of harmful smoke, pollutes working environment.Need not additionally to add water give flue 5 and seal.
This equipment uses spray nozzle injection to be dissolved with NaOH, CaCO3Solution carry out double alkali method desulfurizing.Double alkali method desulfurizing technical matters feature: desulfuration efficiency more than 99%；Desulfurizing agent uses soda and Calx, and in tower, clear liquid absorbs, and is prevented effectively from fouling in tower；Liquid-gas ratio is little.Can desulphurizing and dust-removing integral；Reduced investment, operating cost is low.
In sum.This equipment carries out humidity discharging on the premise of ensureing the quality of fire refractory brick goods, the desulfurization of the useless cigarette of sintering processes, and significant desulfurization effect improve.
Accompanying drawing explanation
