For long-pending steel, its weight and price are below steel, and lined steel pipe, are greatly enhanced the intensity of heat exchanger tube, it is not necessary to use height
The aluminium alloy of price.The cold-forming property of aluminum is superior, is easily processed into shape at normal temperatures.Existing air preheat intracavity is all one way
Tubulation, heat exchange efficiency is not the highest.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, efficient heat transfer anti-low-temperature corrosion easy to use horizontal
Air preheater, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
Efficient heat transfer anti-low-temperature corrosion Horizontal air preheater, including main body, dividing plate, heat exchanger tube and breast hole, described master
The left end of body is provided with left end cap, and the right-hand member of main body is provided with right end cap, is provided with dividing plate in left end cap, dividing plate left end cap is divided into into

Having a cavity, the lower end of right end cap is provided with a breast hole；Several horizontally disposed heat exchange it are provided with side by side in described main body
Pipe, the right-hand member of heat exchanger tube connects with cavity；The upper end of described main body is provided with wind-collecting cover, and upper wind-collecting cover is provided with air inlet
Mouthful, the lower end of main body is provided with lower wind-collecting cover, and the lower end of lower wind-collecting cover is provided with air outlet slit；Described heat exchanger tube is anti-corrosion alloy steel,
The outside of heat exchanger tube is coated with one layer of aluminum pipe, and the outside of heat exchanger tube is provided with fin, fin by aluminum pipe is carried out hot extrusion formation,
And fin is screw type, and the heat exchanger tube in the middle of adjacent fins is provided with thread groove.
Further: described breast hole is communicated in cavity.
Further: on the heat exchanger tube in the middle of described thread groove and adjacent fins, to be all coated with one layer of thin aluminium lamination.
Compared with prior art, simple in construction of the present utility model, easy to use, flue gas first from flue gas inlet pipe enter into into
In air cavity, in then flue gas enters into cavity, then flue gas enters in outlet chamber in cavity again, and last flue gas goes out from flue gas
Pipe discharging, thus add flue gas stroke in main body, improve heat exchanger effectiveness；The fin and the thread groove that arrange can increase
The heat exchange area of big heat exchanger tube, thus improve heat exchanger effectiveness further.
