Description
Technical field
This utility model relates to brick and tile baking equipment, is specifically related to a kind of mobile tunnel furnace baking flue gas processing equipment,
This equipment is utilized can effectively to 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 is compared with traditional annular kiln and tunnel
Road kiln has a lot of advantageous advantage.But, the bottleneck problem that always govern its development is exactly that cigarette vapour processes problem, specifically
For after waste gas and brick bat drying produce water vapour focus on problem.
There is two ways in the market to process cigarette vapour: mode one, by the most any process of cigarette vapour, directly discharge
In air.The benefit of this mode maximum is exactly that the discharge of cigarette vapour need not change the pressure balance within kiln in fact
Existing, do 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 exactly
By the draft of blower fan, all main air ducts, branch air duct are formed negative pressure, waste vapour is collected.This just have impact on whole kiln
Pressure balance, the roasting on brick creates the biggest impact.In brief: humidity discharging, desulfurization to process and will make whole kiln
The firing pressure of stove is unstable, thus affects roasting, finally affects the quality of goods.It is thus desirable to provide one i.e. to possess row
Tide, desulfurization possess again the technical scheme made the best of both worlds ensureing baked article quality.And the desulfurization energy of existing desulfurizer
Power has much room for improvement.
Summary of the invention
This utility model overcomes the deficiency of background technology to provide mobile tunnel furnace baking flue gas processing equipment, design
Purpose 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 desulfurized effect
Significantly improve.
This utility model provides following technical proposals: mobile tunnel furnace baking flue gas processing equipment, including kiln and
The smoke exhaust pipe of described kiln connection, desulfurizer, described desulfurizer contains the Smoke that storage barn is connected with described storage barn
Flue that road is connected with described smoke duct, desulfurizing tower, described flue is connected to one end of transition conduit, described transition conduit
The other end be connected with the air inlet of described desulfurizing tower, the gas outlet of described desulfurizing tower connects chimney.

Further, the inwall of described desulfurizing tower is provided with spray nozzle, and the injection of described spray nozzle is dissolved with NaOH, CaCO3Molten
Liquid.
The beneficial effects of the utility model: this technology is by setting up a sealing device at kiln crown, stores up barn 3.Will be all
Flue gas inside, is delivered in desulfurizing tower by fume centralized the most again that emit by blower fan.This storage barn 3 is the most quite
In simulating a natural space, 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, institute
State tank 8 to connect with described water cavity 9.The globule that sintering produces is collected to tank 8 by this design cleverly, then by tank 8
In water body by tuber drainage in the water cavity 9 of four walls of flue 5, flue is realized water-stop, it is to avoid letting out of harmful smoke
Leakage, 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 skill
Art process characteristic: desulfuration efficiency more than 99%；Desulfurizing agent uses soda and Calx, and in tower, clear liquid absorbs, and is prevented effectively from knot in tower
Dirt；Liquid-gas ratio is little.Can desulphurizing and dust-removing integral；Reduced investment, operating cost is low.
In sum.Carry out on the premise of the quality of this equipment guarantee fire refractory brick goods at the desulfurization of humidity discharging, the useless cigarette of sintering
Reason, and significant desulfurization effect raising.
Accompanying drawing explanation
Fig. 1 is the structure diagram of mobile tunnel furnace baking flue gas processing equipment described in the utility model.
Detailed description of the invention
This utility model is further described with specific embodiment below in conjunction with accompanying drawing.
In Fig. 1: kiln 1, smoke exhaust pipe 2, storage barn 3, smoke duct 4, flue 5, desulfurizing tower 6, transition conduit 7, tank 8,
