Abstract
The utility model relates to a dryer utilizing residual heat of exhaust gas. A plate type gas-gas heat exchanger, an air heater and a fan are placed at the top of the dryer, wherein the plate type gas-gas heat exchanger is arranged in an exhaust channel of the fan, and is provided with a dry air inlet and an outlet; the dry air outlet of the plate type gas-gas heat exchanger is connected with a dry air inlet of the air heater; and a connecting channel is arranged between a high-temperature dry air outlet of the air heater and an inlet of a drying inner cylinder. With the adoption of an exhaust gas residual heat recovery system, energy conservation and emission reduction can be realized; and low-temperature dry air can exchange heat with exhausted wet and hot air through the plate type gas-gas heat exchanger, and the dry air after temperature rise can enter the air heater for exchanging heat with steam, so that the energy consumption can be greatly reduced and the heat and humidity pollution to environment caused by the wet and hot air can be further relieved. The dryer is simple in structure, good in safety, high in drying efficiency and strong in operability.

Summary of the invention
For overcome above-mentioned conventional electric heating type and vapor heating type dryer high energy consumption, to shortcoming and defect such as outdoor thermal pollution are big, task of the present utility model provides a kind of dryer that utilizes exhaust heat, and it can reach low energy consumption, drying efficiency height, the little purpose of thermal pollution.
Technical solution of the present utility model is as follows:
A kind of dryer that utilizes exhaust heat comprises shell, rotatable dry inner core, blower fan, air heater, board-like gas-gas heat exchanger and connecting pipe;
Described board-like gas-gas heat exchanger, air heater and blower fan are placed in the dryer top;
Board-like gas-gas heat exchanger is set in the described blower fan exhaust passage;
Described board-like gas-gas heat exchanger is provided with dry air import and outlet, and board-like gas-gas heat exchanger dry air outlet is connected with the import of air heater dry air;
Between the high temperature drying air outlet slit of described air heater and the dry inner core import interface channel is set.
Screen pack is equipped with in described blower fan exhaust passage import department.
Screen pack is equipped with in described board-like gas-gas heat exchanger dry air import department.
Described air heater is provided with the condensate water outlet.
Described air heater is provided with steam inlet.
The advantage and the good effect of the dryer of exhaust heat of utilizing of the present utility model is: adopt the exhaust heat recovery system, energy-saving and emission-reduction, the dry air of the low temperature damp-heat air by board-like gas-gas heat exchanger and discharge is carried out heat exchange, dry air after the intensification enters air heater and steam heat-exchanging, therefore greatly reduce energy consumption, and reduced the hot wet soiling of damp-heat air environment.The utility model is simple in structure, and security is good, and the drying efficiency height is workable.
Description of drawings
Accompanying drawing is a kind of structural representation that utilizes the dryer of exhaust heat of the present utility model.
Reference numeral:
1 is blower fan, and 2 is board-like gas-gas heat exchanger, and 3 is the exhaust passage, and 4 are the outlet of air heater condensate water, and 5 is the air heater steam inlet, and 6 is air heater, and 7 is the high temperature drying air duct, and 8 is plate type heat exchanger and air heater interface channel.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Referring to accompanying drawing, the utility model provides a kind of dryer that utilizes exhaust heat, mainly is made up of shell, rotatable dry inner core, blower fan 1, air heater 6, board-like gas-gas heat exchanger 2 and connecting pipe.
Board-like gas-gas heat exchanger 2, air heater 6 and blower fan 1 are placed in the dryer top.Blower fan is provided with board-like gas-gas heat exchanger 2 in 1 exhaust passage 3.Board-like gas-gas heat exchanger 2 is provided with dry air import and outlet.Air heater 6 is provided with dry air import and outlet; Air heater 6 also is provided with condensate water outlet and steam inlet.
Board-like gas-gas heat exchanger 2 dry airs outlet is connected with air heater 6 dry air imports.Between the high temperature drying air outlet slit of air heater 6 and the dry inner core import interface channel is set.
Screen pack is equipped with in 3 import departments in blower fan 1 exhaust passage.In board-like gas-gas heat exchanger 2 dry air import departments screen pack is installed, dry air enters board-like gas-gas heat exchanger 2 and exhaust gas heat exchanging by import.
The course of work of a kind of dryer that utilizes exhaust heat of the present utility model is as follows:
After damp-heat air in the drier inner core is extracted out by blower fan 1, filtration by screen pack enters the board-like gas-gas heat exchanger 2 in the exhaust passage 3, dry air is by the dry air import of the board-like gas of blower fan 1 suction-gas heat exchanger 2, dry air filters laggardly to go into board-like gas-gas heat exchanger 2 and carry out heat exchange with damp-heat air by screen pack, and the damp-heat air after the cooling is discharged to outdoor by exhaust passage 3.Dry air after the intensification enters air heater 6 by the board-like gas-gas heat exchanger 2 and the interface channel 8 of air heater 6, high-temperature steam enters air heater 6 by air heater steam inlet 5 and carries out exchange heat with dry air, the high-temperature steam of emitting latent heat is condensed into condensate water, discharge air heater 6 by air heater condensate water outlet 4, dry air becomes the high temperature drying air after absorbing the steam liberated heat, enters dry inner core by the high temperature drying air duct 7 that connects air heater 6 and dry inner core wet stock is carried out drying.
In summary, the dryer of exhaust heat that utilizes of the present utility model adopts the exhaust heat recovery system, energy-saving and emission-reduction, the dry air of the low temperature damp-heat air by board-like gas-gas heat exchanger and discharge is carried out heat exchange, dry air after the intensification enters air heater and steam heat-exchanging, therefore greatly reduce energy consumption, and reduced the hot wet soiling of damp-heat air environment.The utility model is simple in structure, and security is good, and the drying efficiency height is workable.
