Description
Technical field
The present invention relates to waste gas recovery reutilization technology field, particularly relate to a kind of boiler exhaust gas recycle device.
Background technology
Small and Medium Enterprises in China produces and concentrated supply of heating in the city boiler is based on coal-burning boiler at present, and wherein most is chain
Bar boiler, the tail gas that existing chain-grate boiler produces directly is discharged by tail gas outlet tube, containing a large amount of nitrogen in the tail gas given off
Oxygen compound, pollutant atmosphere.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose one and can substantially reduce oxynitride content in tail gas, significantly
Reduce the environment-friendly type chain-grate boiler device for recovering tail gas of discharge.
The present invention is achieved through the following technical solutions technical goal.
Environment-friendly type chain-grate boiler device for recovering tail gas, is arranged on the tail gas outlet tube side of chain-grate boiler；Described chain pot
Stove includes combustion system, electric controling assembly；It thes improvement is that: described environment-friendly type chain-grate boiler device for recovering tail gas includes
Tail gas recycle pipe；Described tail gas recycle pipe one end connects from side and connects tail gas outlet tube, and the other end is connected to chain-grate boiler
Combustion system.
In said structure, described tail gas recycle pipe is provided with air-introduced machine.
In said structure, described tail gas outlet tube, tail gas recycle pipe junction are provided with electromagnetic distribution valve.
In said structure, in described chain-grate boiler, it is provided with temperature sensor；Described electric controling assembly and temperature sensor,
Electromagnetic distribution valve, air-introduced machine are electrically connected with.
In said structure, described temperature sensor is remote sensing thermometric control head.
The present invention compared with prior art, has the positive effect that:
1. tail gas discharge system is provided with tail gas recycle pipe, sends a tail gas part for generation back to burner hearth again, decrease air
Input, the inert gas content that tail gas contains is more, and oxygen content is less, and stove chamber inner combustion speed will slow down, thus slows down
Pressure initiation process in combustor, reduces the generation of oxynitride.Therefore, when chain-grate boiler input coal dust, input
Oxygen content is less, reduces in burner hearth in maximum combustion temperature and burner hearth O in gaseous mixture2Volume fraction, destroy NOx life
Become environment, thus reduce the discharge of NOx.
2. tail gas recycle pipe is provided with air-introduced machine, the dynamics sucking tail gas in tail gas recycle pipe can be increased.
3. it is provided with temperature sensor in chain-grate boiler, at tail gas outlet tube and tail gas recycle pipe, sets electromagnetic distribution valve, tail gas
Setting air-introduced machine in recovery tube, temperature sensor, electromagnetic distribution valve are electrically connected with electrical equipment control assembly, are surveyed by temperature sensor
Amount fire box temperature, passes the signal along to electrical equipment control assembly, electrical equipment control assembly sends letter to air-introduced machine, electromagnetic distribution valve
Number, control tail gas input quantity, tail gas input speed respectively by electromagnetic distribution valve, air-introduced machine, to reach preferable combustion efficiency
And emission effect, it is achieved that the intelligentized control method that tail gas recycle utilizes.
4. temperature sensor is remote sensing thermometric control head, can be placed in remote position and measures fire box temperature.
