In order to be more clearly understood the advantages of making the purpose of this utility model and technical solution, below in conjunction with attached drawing and reality
Example, the present invention will be further described in detail.
As shown in attached drawing 1 ~ 5, waste heat of boiler tail gas recycle device, including the air inlet 1 that one end is connect with boiler, into
The other end of port 1 is connected with dust-fall pipe 2, adjuster 3 and the heat exchange mechanisms 4 of serpentine in turn, and the heat exchange mechanisms 4 are whole to be in
Cuboid-type structure, including cabinet 41 and the case lid 42 being mounted at the top of cabinet 41, along 41 length direction of cabinet in cabinet 41
Opposite two sides are equipped with gas inlet 411 and exhanst gas outlet 412, and the adjuster 3 is connect with gas inlet 411, along cabinet 41
Length direction is installed in cabinet 41 there are three heat exchanger 43, and the heat exchanger 43 is whole cylindrical, including hollow round pie
Upper cavity 431 and lower chamber 432, equidistantly vertically installed between the upper cavity 431 and lower chamber 432 with circular manner
There are three groups of heat exchange units 433, every group of heat exchange unit 433 is made of the thermally conductive sheet 4331 of several hollow arcs, thermally conductive sheet 4331
It is equally spaced in concentric structure mode, 43 outside of concave surface directionization heat exchanger, from close to 43 center of heat exchanger to outside
It is gradually reduced to 4331 arc length of thermally conductive sheet, 4331 upper and lower ends of thermally conductive sheet are formed with upper cavity 431 and the conducting of lower chamber 432 respectively
One fan-shaped heat exchange area offers on circular respectively at the corresponding cabinet 41 of each heat exchanger 43 and 42 position of case lid
Step 413 and get out of a predicament or an embarrassing situation 421,431 installation by adhering of upper cavity is in top bar 413 and in 431 upper surface of upper cavity
Water inlet pipe 44 is equipped at the position of centre and water inlet pipe 44 extends to outside case lid 42 and is equipped with gear 45 and cooperation on outer side wall
The gear motor used, 432 installation by adhering of lower chamber is being got out of a predicament or an embarrassing situation in 421, in 432 lower surface of lower chamber and leave from office
It is offered at corresponding position on 421 bottom surface of rank several in the annular groove 46 of concentric structure arrangement and in each annular groove 46
Several spin cooperated with annular groove 46 are inside installed, 432 lower surface central position of lower chamber be equipped with outlet pipe 47 and
Outlet pipe extends to outside cabinet 41.
The adjuster 3 is in hollow trapezoid shape platform structure, and narrow end is towards heat exchange mechanisms 4.
The gas inlet 411 is identical with 412 size of exhanst gas outlet, is in rectangular aperture shape, and width is the outlet of dust-fall pipe 2
Hold the 1/2 of diameter, highly 4/5 for 4331 height of thermally conductive sheet.
The working method of the utility model are as follows:
The high-temperature flue gas that boiler generates is introduced from air inlet 1, when by 2 bend of dust-fall pipe, since centrifugal action makes cigarette
Part dust and tail gas separation in gas gather 2 inner wall vicinity of dust-fall pipe, reduce the influence of dust heat exchanging mechanism.Flue gas
Enter in adjuster 3 from dust-fall pipe 2, since space becomes larger, flue gas flow rate can be reduced, and play the role of buffering and auxiliary depositing dust.
Flue gas, which enters in cabinet 41 after adjusting from gas inlet 411, successively carries out heat exchange with three heat exchangers 43.20 ~ 30 DEG C low
Warm cold water enters water pipe 44 certainly and enters in upper cavity 431 and then pass through from thermally conductive sheet 4331, flows into lower chamber 432.It leads
Backing 4331 is process by the material of high fever coefficient, when flue gas passes through from thermally conductive sheet 4331, realizes heat exchange.After heat exchange
Water is discharged from outlet pipe 47.In heat transfer process, gear motor independently drives corresponding gear 45, and in lower chamber 432 and leaves office
Under annular groove and the spin cooperation of rank 421, heat exchanger 43 is rotated with the speed of 10 ~ 20rpm.Since thermally conductive sheet 4331 is in same
Heart circle frame mode is equally spaced, and the path side length that flue gas passes through from heat exchange unit 433 increases heat-exchange time.Simultaneously as
Synchronous rotary makes flue gas change therewith by way of heat exchange unit 433, and flue gas forms turbulent flow in cabinet 41, also increases
Heat-exchange time is added, has improved heat exchange efficiency, the flue gas after heat exchange is released from exhanst gas outlet 412.
