Abstract
The utility model discloses a kind of boiler blow-off heat reclamation device, the discharge pipe line of boiler is connected with cesspool, and heat exchange unit is disposed with the cesspool, and normal temperature air is delivered in burner after carrying out heat exchange with high temperature sewage by the airflow pipeline of heat exchange unit.Normal temperature air carries out heat exchange with high temperature sewage, it is delivered to again in burner after normal temperature air heat absorption heating, improve the thermal efficiency of boiler, the blowdown heat of recovery boiler, the waste of the energy is reduced as far as possible, and the heat exchange unit in cesspool shortens high temperature sewage temperature fall time, sewage in cesspool is reached the temperature standard that can be discharged as early as possible, prevent that sewage tankage is small, avoid sewage overflows in cesspool.
Description
Technical field
Field of boilers is the utility model is related to, specially a kind of boiler blow-off heat reclamation device.
Background technology
During boiler blow-off, temperature during high temperature sewage discharge to the cesspool of boiler is up to 70 DEG C -80 DEG C, due to
Influence of the temperature to microorganism is very extensive, and high temperature sewage, which needs to be reduced to 30 DEG C or so, just to be allowed to be emitted into city planting ductwork.
Therefore, the sewage that boiler emission comes out, which needs first to be emitted into cesspool, carries out cooling processing, and such boiler blow-off heat can not reclaim,
Cause huge energy waste.
Utility model content
The purpose of this utility model is to provide a kind of boiler blow-off heat reclamation device, and the blowdown heat of recovery boiler is to improve
The thermal efficiency of boiler.
To achieve these goals, the technical scheme used for：A kind of boiler blow-off heat reclamation device, the drainpipe of boiler
Road is connected with cesspool, and heat exchange unit, the airflow pipeline and height that normal temperature air passes through heat exchange unit are disposed with the cesspool
Warm sewage is delivered in burner after carrying out heat exchange.
Compared with prior art, technique effect of the present utility model is：Normal temperature air carries out heat exchange with high temperature sewage, often
It is delivered to again in burner after warm air heat absorption heating, improves the thermal efficiency of boiler, the blowdown heat of recovery boiler, as far as possible
The waste of the energy is reduced, and the heat exchange unit in cesspool shortens high temperature sewage temperature fall time, uses up sewage in cesspool
Reach the temperature standard that can be discharged soon, prevent that sewage tankage is small, avoid sewage overflows in cesspool.
Brief description of the drawings
Fig. 1 is the schematic diagram after the completion of the utility model arrangement；
Fig. 2 is the utility model blowdown recuperation of heat schematic diagram.
Embodiment
The utility model is described in further detail with reference to Fig. 1 and 2.
A kind of boiler blow-off heat reclamation device, the discharge pipe line of boiler 1 connect with cesspool 2, are arranged in the cesspool 1
There are heat exchange unit 10, normal temperature air to be delivered to burning after carrying out heat exchange with high temperature sewage by the airflow pipeline of heat exchange unit 10
In device 20.
In such scheme, heat exchange unit 10 is disposed with cesspool 1, normal temperature air carries out heat exchange with high temperature sewage,
It is delivered to again in burner 20 after normal temperature air heat absorption heating, compared with directly conveying normal temperature air, improves the thermal effect of boiler
Rate, the blowdown heat of recovery boiler, the waste of the energy is reduced as far as possible, and the heat exchange unit 10 in cesspool 1 shortens height
Warm sewage temperature fall time, sewage in cesspool 1 is reached the temperature standard that can be discharged as early as possible, prevent that the capacity of cesspool 1 is small, keep away
Exempt from sewage overflows in cesspool 1.
The heat exchange unit 10 is finned heat exchanger.Heat exchange unit 10 has multiple choices scheme, wing of the present utility model
Plate heat interchanger is easy for installation above cesspool, is easy to safeguard, the heat pipe of finned heat exchanger can be directly protruding into high temperature sewage
It is interior.
Claims (2)
