Further, it is provided with accumulation of heat porous brick in the waste gas combustion furnace.
Further, the outlet of the waste gas combustion furnace is connected with waste heat recovery and flue gas processing device.
Further, the security system also includes being connected to the bypass pneumatic operated valve of exhaust gas entrance, and the bypass pneumatic operated valve connects
It is connected to urgent bypass line.
Further, it is provided with explosion proof door on the waste gas combustion furnace.
Further, in the exhaust pipe waste gas flow velocity in below 8m/s.
The present invention has following Advantageous Effects：
It is quick-fried that the security system of the application limits and eliminate burning of the waste gas when course of conveying, waste gas combustion furnace run
Fried interaction between danger, oxidizer, ignition source three, prevents tempering burning " three elements " while appearing together；
The generation of the accident that device is on fire when burning conveying so as to effectively prevent, explode.
Brief description of the drawings
Fig. 1 is the implementing procedure figure that burned waste gas of the invention convey explosion-proof anti-backfire security system；
Fig. 2 is the use state structural representation that burned waste gas of the invention convey explosion-proof anti-backfire security system；
Fig. 3 is the partial enlarged drawing at A in Fig. 2.
Specific embodiment
Below, refer to the attached drawing, is more fully illustrated to the present invention, shown in the drawings of exemplary implementation of the invention
Example.However, the present invention can be presented as various multi-forms, the exemplary implementation for being confined to describe here is not construed as
Example.And these embodiments are to provide, so that the present invention is fully and completely, and will fully convey the scope of the invention to this
The those of ordinary skill in field.
As shown in Figure 1-2, explosion-proof anti-backfire security system is conveyed invention provides a kind of burned waste gas, this is safely
System includes just leading to pneumatic operated valve 1, pressure-regulating valve 2, ratio adjusting valve 3, useless from what discarded entrance passed sequentially through exhaust pipe connection
Throughput detection meter 4, check-valves 5, spark arrester 6, pipeline cooler 7, waste gas nozzle 8 and waste gas combustion furnace 9.
Exhaust pipe be stainless steel pipeline or steel pipeline, and exhaust pipe be grounded；Stainless steel pipeline or steel
Tubulation road ensure that the mechanical strength of pipeline, and pass through to be grounded the effect for serving lightning protection, antistatic.
Pressure detecting instrument 10 is respectively connected with the exhaust pipe in check-valves 5 and the downstream of spark arrester 6.Ensure to enter burned waste gas
Conveyed in malleation (800-1000Pa), (illustrate have refluence tempering existing in now exhaust pipe when occurring negative pressure in exhaust pipe
As), pressure detecting instrument 10 feeds back signal to controller, and controller controls the positive ventilation movable valve of exhaust gas inlet, closes immediately just
Siphunculus road, prevents waste gas from continuing to flow backwards spreading for tempering, now bypasses pneumatic operated valve and automatically opens up, and conveying waste gas enters urgent bypass
Emergent discharge.
Security system also includes control system, and control system includes controller and the waste gas being arranged on after pipeline cooler 7
Pressure sensor 11 on pipeline, pressure sensor 11 is connected with controller, and controller is connected with just logical pneumatic operated valve 1；Controller
Can be PLC etc..
Exhaust gas flow detection meter 4 is connected on the exhaust steam passage of security system by bypass conduit.
Accumulation of heat porous brick 12 is provided with waste gas combustion furnace 9, the setting of accumulation of heat porous brick 12 increased waste gas mixing contact
Area so that organic exhaust gas burning is more abundant.
The outlet of waste gas combustion furnace 9 is connected with waste heat recovery and flue gas processing device.
Security system also includes being connected to the bypass pneumatic operated valve 13 of exhaust gas entrance, and bypass pneumatic operated valve 13 is connected with urgent bypass
Pipeline.
Explosion proof door 14 is provided with waste gas combustion furnace 9.
Waste gas flow velocity is in below 8m/s in exhaust pipe.
Pipeline cooler 7 is connected with circulating water chennel.The effect of pipeline cooler 7 is to be cooled down waste gas pipeline road,
Avoid when occurring flowing backwards high temperature in exhaust pipe, when high-temp waste gas carry out occurring flowing backwards, the effective high temperature blocking of cooler is prevented
Only combustible waste gases can form physical explosion in exhaust pipe with high temperature.
Spark arrester 6 is anti-detonation type spark arrester, and anti-detonation type spark arrester can be when exhaust pipe prevents detonation and detonation
Flame is prevented to puncture.It is prevented from, due to there is the tempering that long-time stable is burnt and caused on back-fire relief disk, gas being born
The HTHP that body/air mixture explosion time is produced.
When the setting of check-valves 5 gas backflow can occur in exhaust pipe, waste gas is automatically cut off.
The waste gas total flow being disposed in monitoring exhaust pipe of exhaust gas flow detection meter 4, it is ensured that in exhaust pipe
Waste gas without departing from design total flow.
Being disposed to of pressure-regulating valve 2 and ratio adjusting valve 3 prevents the waste gas in exhaust pipe from exceeding design pressure
And flow, the pressure in exhaust pipe is adjusted, influence of the exhaust gas pressure to explosion limit is more complicated, generally, pressure
Increase, explosion limit scope expands；Pressure reduces, explosion limit range shorter.Control exhaust gas pressure and flow will ensure that waste gas
Stable and uniform delivers into waste gas combustion furnace.
Bypass pneumatic operated valve 13 is disposed to occur having a power failure in waste gas course of conveying, occurs in exhaust pipe flowing backwards negative
Pressure, waste gas stove auxiliary burner is flame-out, flame detector is detected in burner hearth carries out waste gas emergency cut-off under the state such as flame-out, controls
Spread with the tempering of limitation exhaust pipe and contingency.
It is described above simply to illustrate that of the invention, it is understood that the invention is not limited in above example, meet
The various variants of inventive concept are within protection scope of the present invention.
