Description
Technical field
The present invention relates to energy-conserving and environment-protective technical fiel, specially cleans heat exchange type flue gas cooling device.
Background technology
Flue gas cooling device is cooled down frequently as high-temperature flue gas and used, at present high temperature at home in various stove dust pelletizing systems
Generally used in flue gas dust collecting system, and design and use for many years, it is found that the flue dust in flue gas extremely influences flue gas cooling
The using effect of device, i.e., because flue dust property caused by each stove is different, the influence to flue gas cooling device is also different,
Some is in heat-exchange tube（Plate）Upper dust stratification even blocks exhaust gases passes, some heat-exchange tubes（Plate）By flue dust erosive wear, also
The cooling effectiveness of flue gas can be reduced, shortens the service life of equipment, so as to influence the normal operation of flue gas dust collecting system.
The content of the invention
In view of the above-mentioned problems, the invention provides cleaning heat exchange type flue gas cooling device, it can reduce flue dust to equipment
Influence, so as to improve flue gas cooling effectiveness, extension device service life, ensure the normal operation of flue gas dust collecting system.
Its technical scheme is that so, it includes the housing being connected in sequence by upper header, middle header, lower collecting box, described
Heat-exchanging tube bundle is arranged in juxtaposition in housing, the lower collecting box bottom is connected with ash bucket, it is characterised in that it also includes by axle stream wind
Machine, the middle header and the lateral outlet of space and the middle header is linked in sequence between its interior heat-exchanging tube bundle part
Cooling duct, Whirlwind cyclone, the heat-exchanging tube bundle end and the discharge tube end pair of the Whirlwind cyclone are provided with the lower collecting box
It should connect to form exhaust gases passes, the upper header is provided with exhanst gas outlet, and the lower collecting box is provided with smoke inlet.
It is further characterized by, and in the enclosure interior, the flue gas flow direction and cooling airflow are to vertical.
The invention has the advantages that flue gas enters lower collecting box by smoke inlet, and it is further separated into Whirlwind cyclone, flue gas edge
Whirlwind cyclone inwall from top to bottom makees spiralling, after inwall bottom is reached then upward, rotates up along axle center, most passes through afterwards
Discharge pipe is discharged；And flue gas is when rotating, the flue dust in flue gas wants inward wall to move under the promotion of centrifugal inertial force
It is dynamic, the flue dust of inwall is reached under the collective effect of air-flow and gravity, is fallen into along internal face in ash bucket, has been reached the mesh of dedusting
, then the flue gas after dedusting, which is passed through in heat-exchanging tube bundle, is cooled down, and because flue gas passes through dedusting, then flows through heat-exchanging tube bundle
Flue gas is cleaner, avoids the dust stratification in heat-exchanging tube bundle and abrasion, reduces flue gas collateral resistance, reduces operating cost,
Reduce influence of the flue dust to equipment, so as to improve the service life of the cooling effectiveness of flue gas and extension device, ensure that cigarette
The normal operation of gas dust pelletizing system.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is A-A in Fig. 1 to profile.
Embodiment
As depicted in figs. 1 and 2, the present invention includes the housing being connected in sequence by upper header 2, middle header 4, lower collecting box 5,
Heat-exchanging tube bundle has been arranged in juxtaposition in housing, the heat exchanger tube 3 for forming heat-exchanging tube bundle is arranged with in-line arrangement or staggered pattern, under
The bottom of header 5 is connected with ash bucket 7, and it also includes by two axial flow blowers 1, middle header 4 and it with its interior heat-exchanging tube bundle part
Between the cooling duct that is linked in sequence of the lateral outlet of space and middle header 4, be provided with Whirlwind cyclone 6 in lower collecting box, Whirlwind cyclone 6 is made
Being used for the dust removal component of equipment, heat-exchanging tube bundle end is corresponding with the discharge tube end of Whirlwind cyclone 6 to be connected to form exhaust gases passes,
Upper header 2 is provided with exhanst gas outlet, and upper header 2 is flue gas collector-shoe gear, and exhanst gas outlet connects with flue, and lower collecting box 5 is set
Smoke inlet is equipped with, in enclosure interior, flue gas flow direction and cooling airflow are to vertical.
The course of work of the present invention is that flue gas enters lower collecting box 5 by smoke inlet, then flue gas shunting into number with ten ~
The Whirlwind cyclone 6 of hundred meters, flue gas move as spiral rotating from top to bottom along the inwall of Whirlwind cyclone 6, when arrival Whirlwind cyclone 6 inwall bottom
Afterwards then upwards, rotate up along axle center, most discharged afterwards through discharge pipe, and flue gas is when rotating, the flue dust in flue gas
Separated under the promotion of centrifugal inertial force with flue gas, and inward wall moves, reach the flue dust of inwall in the common of air-flow and gravity
Under effect, it can periodically be discharged after falling into ash bucket 7 along internal face, reached the purpose of dedusting；Discharged by the discharge pipe of Whirlwind cyclone 6
Clean flue gas enters heat exchanger tube 3, is flowed from bottom to top in heat exchanger tube 3, forces to blow with axial flow blower 1 by the tube wall of heat exchanger tube 3
The air entered carries out indirect heat exchange, and flue-gas temperature, which reduces, to be cooled, and because flue gas passes through dedusting, then flows through the cigarette of heat-exchanging tube bundle
Gas is cleaner, avoids the dust stratification in heat-exchanging tube bundle and abrasion, reduces flue gas collateral resistance, reduces operating cost, also subtracts
Lack influence of the flue dust to equipment, so as to improve the service life of the cooling effectiveness of flue gas and extension device, ensure that flue gas
The normal operation of dust pelletizing system, after the flue gas after cooling collects into upper header 2, discharged by the exhanst gas outlet of upper header 2, cooling
Air is introduced by axial flow blower 1, header 4 in being entered by the air intlet of middle header 4 being connected with axial flow blower 1, is then passed through
Passage between heat exchanger tube 3, air is finally discharged into by the middle air outlet slit of header 4, the air in middle header 4 between heat exchanger tube 3,
Indirect heat exchange is carried out by the tube wall of heat exchanger tube 3 with flue gas in heat exchanger tube 3, temperature raises after cooled flue gas, and the heat after heating is empty
Gas is discharged into air.
