Description
Technical field
The utility model relates to technical field of heat exchange devices, specially a kind of air preheater of good effect of heat exchange.
Background technique
Requirement with the country to energy-saving and emission-reduction is higher and higher, and energy cost accounting of the boiler in enterprise is very high, therefore
The thermal efficiency of boiler is improved, fuel consumption is reduced, is had a very important significance to energy consumption is reduced.It is worth noting that smoke evacuation
Loss occupies great ratio in the heat loss of heating furnace, and reducing exhaust gas temperature to reduce heat loss due to exhaust gas is energy-saving and emission-reduction
One of behave.Currently, common air heat exchanger Mist heat recovering, improves thermal efficiency of heating furnace.Wherein heat-pipe air preheater
It is high, small in size with its heat exchange efficiency, not by process flow constraint etc. advantages obtained widely answering in boiler afterheat recycling field
With.
Existing heat tube preheater includes cabinet, and cabinet is divided into air duct and exhaust gases passes by partition, passes through
Heat pipe is installed in cabinet, the heat pipe positioned at high-temperature flue gas part absorbs heat, then transfer heat to cold air part into
Row heat release, thus realize heat exchange, but the heat of the exhaust gases passes of existing preheater can be dispersed into external environment by side wall
In, heat cannot efficiently use.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of air preheater of good effect of heat exchange, can efficiently use
Heat in flue gas, good effect of heat exchange.
Its technical solution is such that a kind of air preheater of good effect of heat exchange comprising cabinet, heat pipe, for pacifying
Fill the tube sheet of the heat pipe, it is characterised in that: be connected with flue gas chamber below the tube sheet, the flue gas chamber is located at the case
Internal portion and separate with the cabinet, gas inlet and exhanst gas outlet is each passed through the cabinet and the flue gas chamber connects
It is logical.
It is further characterized by:
Air intlet is connected to the cabinet top respectively with air outlet slit；
Fin is connected on the heat pipe；
Perpendicular to the gas inlet and the exhanst gas outlet be provided with baffle between every heat exhausting pipe on straight line, institute
The height of baffle plate baffle corresponding and adjacent with the height of the flue gas chamber is stated to be respectively fixedly connected in the flue gas chamber
Antetheca and rear wall on, the baffle relative to one end of junction the other end and the flue gas chamber separate to form gap.
After with such a structure, flue gas chamber is located in the box body portion and separates with cabinet, to make it through side
The heat that wall releases is directly entered in the intracorporal cold air of case rather than distributes into external environment, to make in flue gas
A part of heat is entered in cold air by heat pipe heat exchanging, the heat that another part is distributed by flue gas chamber side wall then directly into
Enter in cold air, therefore is effectively utilized the heat in flue gas, good effect of heat exchange.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is A-A to schematic cross-sectional view.
Specific embodiment
The air preheater of a kind of good effect of heat exchange as shown in Figure 1 and Figure 2 comprising cabinet 1, heat pipe 2, for installing
The tube sheet 3 of heat pipe 2, flue gas chamber 4 is connected with below tube sheet 3, and flue gas chamber 4 is welded on made of 3 lower section of tube sheet as steel plate
Closed cavity, flue gas chamber 4 are located at 1 inside of cabinet and separate with cabinet 1, and gas inlet 5 and exhanst gas outlet 6 are each passed through case
Body 1 is connected to flue gas chamber 4, and air intlet 7 is connected to 1 top of cabinet respectively with air outlet slit 8；The support of flue gas chamber 4 can
To be supported by the pipeline of gas inlet 5 and exhanst gas outlet 6, can also by cabinet 1 be arranged support plate come into
Row support；Heat pipe 2 is mounted on tube sheet 3 by big envelope, and the structure and working principle of heat pipe 2 are the prior art, is located at cigarette
It is evaporator section inside air cavity 4, being located at is condensation segment outside flue gas chamber 4, evaporation endothermic after the heat of water absorption high-temperature flue gas,
Liquidation exothermic reaction to the cold after into top, and the water flow formed after liquefying returns evaporator section and forms circulation, and in order to increase heat pipe 2
Heat exchange efficiency can install fin on heat pipe 2；In addition, 1 outer wall of cabinet can use thermal insulation material, increase thermal insulation property, resistance
Only heat is lost.
In order to further enhance heat transfer effect, perpendicular to gas inlet 5 and exhanst gas outlet 6 every heat extraction on straight line
Baffle 9 is provided between pipe 2,9 height of the baffle baffle 9 equal and adjacent with the height of flue gas chamber 4 is respectively welded at cigarette
On the antetheca and rear wall of air cavity 4, baffle 9 separates to be formed centainly relative to the other end and flue gas chamber 4 of one end of junction
Gap, using such structure, flue gas snakes through flue gas chamber 4, increase flue gas in flue gas chamber 4 by the time, from
And further promote heat transfer effect.
By the way that flue gas chamber 4 is placed in 1 inside of cabinet and closes flue gas chamber 4 and cabinet 1 mutually, flue gas chamber 4
Surrounding is in flowing cold air, to make to be directly entered in cold air by the heat that side wall comes out, so not only
It is effectively utilized the heat of flue gas, heat exchange efficiency is high, and by avoiding heat from being dispersed into the external world, ensure that the peace of operator
Entirely.
More than, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is not limited to
In this, any people for being familiar with the technology is in the technical scope disclosed by the utility model, and any changes or substitutions that can be easily thought of,
It should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with claim
Subject to protection scope.
