Description
Technical field
The utility model relates to the construction applications of boiler, in particular to a kind of economizer.
Background technique
Economizer refers in boiler back end ductwork the heating surface for the saturated water being heated into boiler feedwater under drum pressure, by
What it is in its absorption is the flue gas for comparing low temperature, reduces the exhaust gas temperature of flue gas, saves the energy, improves efficiency.
With the extensive use of complete regeneration techniques, waste heat boiler be increasingly being applied to catalysis, cracking unit with
The thermal energy of reclaiming flue gas.Waste heat boiler is compared with general Industrial Boiler, since heat source-regenerated flue gas temperature is lower,
Design when, the ratio that the distribution economizer of thermic load accounts for is very big, thus economizer occupy in waste heat boiler it is considerable
Position.
Therefore, market needs that a kind of purification efficiency is high, drag losses are small, equipment resistance is small, total energy consumption is low, treatment quantity
Greatly, the economizer for allowing operation temperature high.
Utility model content
In view of the deficiencies of the prior art, the utility model discloses a kind of economizers.
Technical solution used by the utility model is as follows:
A kind of economizer, including motor, controller, straight damper, flexural damping device, air treatment system and bottom plate；Electricity
Machine and controller are installed on the side plate of economizer；It is connected between motor and controller by electric wire；Straight damper and bending
Damper is installed between the both side plate of economizer；Ventilation opening is opened up at the top of economizer；It opens the side of the bottom plate of economizer
If return air inlet；Exhaust outlet is opened up between straight damper and flexural damping device；Air treatment system is vertically mounted on bottom plate.
Its further technical characteristic are as follows: the shape of the both side plate of economizer is right-angled trapezium；The both ends of straight damper
The bevel edge of both side plate is installed in the both ends of flexural damping device.
Its further technical characteristic are as follows: the cross sectional shape of exhaust outlet is right angled triangle；The right-angle side of exhaust outlet and province
The right-angle side of the side plate of coal device is overlapped.
Its further technical characteristic are as follows: air treatment system includes tube bank and flue；The bottom of flue is vertically mounted on
On bottom plate；Installation tube bank in flue；Tube bank is vertically disposed finned tube.
The beneficial effects of the utility model are as follows:
1, the heat of low-temperature flue gas is absorbed, treatment quantity is big, reduces exhaust gas temperature, reduces flue gas loss, fuel is saved,
Total energy consumption reduces.
2, it is first heated in economizer since water supply enters before drum, reduces water supply in the heat absorption of heating surface, it can
To replace cost higher evaporating heating surface in part with economizer.
3, feed temperature improves, and will reduce the temperature difference of hearth wall into drum, and thermal stress reduces accordingly, extends vapour
Packet service life.
4, purification efficiency is high, drag losses are small, equipment resistance is small, allows operation temperature high
