Description
Technical field
The utility model is related to technical field of heat exchangers more particularly to a kind of plate air preheaters.
Background technology
Plate air preheater is the important waste heat recovery apparatus of heating furnace, is discharged fume to the waste heat in recovered flue gas, reduction
Temperature and raising heater efficiency have important role.The operation principle of plate air preheater is, heat smoke and cold sky
Gas exchanges heat, and heat smoke temperature reduces, and recycles heat, reaches discharge, and air temperature increases, acquirement heat, as combustion-supporting,
Fuel is saved, this requires heat exchanger channels to have good heat transfer effect.
Plate air preheater is a kind of efficient and compact heat transmission equipment, has heat transfer coefficient high, and the pressure loss is small, knot
Structure is compact, it is easy to maintenance many advantages, such as, therefore, in the prior art generally use plate air preheater, and use corrugated plating
Piece is as heat transfer element, but its disadvantage also can not be ignored, and corrugated plating increases the flow resistance of flue gas and air, need to be equipped with big work(
Rate wind turbine reduces thermal energy consumption loss, but increases power consumption.Meanwhile the preheater of this corrugated plating form is easy to accumulate
Ash, fouling, to reduce service life of equipment, it is necessary to deashing device be set, periodically cleared up, not only so that the knot of equipment
Structure design complicates, and can bring inconvenience to customer because repairing to shut down.
Utility model content
In order to solve the easy dust stratification of existing plate air preheater, fouling, the problem of needing periodic cleaning dust, this practicality is new
The purpose of type is to provide a kind of plate air preheater.
To achieve the goals above, the utility model adopts the following technical solution：A kind of plate air preheater, including change
Hot plate piece, the heat exchange plate include heat exchanger plate body, and the right and left of heat exchanger plate body is bent to form the first folding separately down
Side, the second flanging, the following of the first flanging are bent to form third flanging to the left, and the following of the second flanging is bent to form to the right the 4th
Flanging, the front and back both sides of heat exchanger plate body are folded upward to form the 5th flanging, the 6th flanging respectively, and the top of the 5th flanging is forward
Be bent to form the 7th flanging, the top of the 6th flanging is bent to form the 8th flanging backward, third flanging, Fourth Fold correspondence position
Set and be respectively arranged with the first threaded hole, the 7th flanging, the 8th flanging corresponding position be respectively arranged with the second threaded hole, the first folding
Side and the second flanging, third flanging and Fourth Fold, the 5th flanging and the 6th flanging, the 7th flanging and the 8th flanging are respectively symmetrically
Setting, the upper and lower surface of the heat exchange plate are respectively arranged with fins set, and the fins set is by linear type fin and baffling type wing
Piece is arranged alternately, and the heat exchange plate reverse stack together, forms plate package, forms stream between heat exchange plate two-by-two
Road.
Heat exchange plate reverse stack together, runner will be formed two-by-two, adjacent channels are orthogonal setting, are respectively used to be passed through
Flue gas and air.Runner is linear type, reduces resistance when air-flow flowing, is not easy dust stratification, fouling.The tow sides of heat exchange plate
It is respectively arranged with fins set, fins set accelerates heat transfer, improves the heat exchange property between flue gas and air.
Preferably, the baffling type fin includes diversion division and baffling portion, the folder between the diversion division and baffling portion
Angle is 10-90 °.
When air-flow enters baffling portion by diversion division, the flow direction of air-flow changes, multiple linear type fins and baffling
Type fin is used alternatingly so that air-flow generation cocurrent replaces with adverse current, and the angle between diversion division and baffling portion is smaller, cocurrent
Higher with the frequency of adverse current, heat transfer effect is better；But the angle between diversion division and baffling portion is smaller, the flowing resistance of air-flow
Power is bigger, and flow rate is slack-off, influences heat transfer rate.
It is further preferred that the angle between the diversion division and baffling portion is 10-25 °.
When the angle between diversion division and baffling portion is 10-25 °, the heat transfer effect between flue gas and air and heat exchange speed
Degree can reach industrial applicability requirement.
Wherein, the heat exchange plate is stainless steel.
Compared with prior art, advantageous effect of the utility model：The utility model plate air preheater, stream
Road is mostly linear type, is not easy dust stratification, fouling, and the tow sides of heat exchange plate are respectively arranged with fins set, and fins set accelerates heat transfer,
Improve the heat exchange property between flue gas and air.
