A kind of warning device for fly-ash separator spontaneous combustion and using method thereof
Technical field
The present invention relates to coating room sandblast ventilating dust-removing technology field, specifically a kind of in inner warning device and the using method thereof that a kind of fly-ash separator spontaneous combustion is installed of fly-ash separator.
Background technology
In the newly-increased painting shop of present stage China, sandblast ventilating and purifying air system is a set of requisite ingredient, and its function of mainly undertaking is the dust producing in sandblast process, the mode of filtering through fly-ash separator, the air after purifying, be disposed in atmosphere.
Sandblast ventilating and purifying air system is generally by dedusting fan, the compositions such as fly-ash separator, ventilating duct.In dust removal process, metallic dust rubs and produces static in fly-ash separator, and fly-ash separator is interior and easily produce Mars, and then causes fire.By it, in sand blasting room when repair welding workpiece, the Mars that welding produces sucks fly-ash separator, and fly-ash separator inside is spontaneous combustion, breaking out of fire.
Summary of the invention
The object of the present invention is to provide a kind of warning device and using method thereof of improved fly-ash separator spontaneous combustion, it can overcome in prior art sandblast ventilating and purifying air system and spontaneous combustion easily occurs but there is no the some shortcomings of corresponding warning device.
To achieve these goals, technical scheme of the present invention is: a kind of warning device for fly-ash separator spontaneous combustion, it is characterized in that: described warning device is made up of passive infrared warning device, signal acquisition module and controller, passive infrared warning device is connected with signal acquisition module, and signal acquisition module is connected with controller.
For a using method for the warning device of fly-ash separator spontaneous combustion, it is characterized in that: described using method comprises the steps: a, in the time that coating room carries out sandblast operation, successively open fly-ash separator and dedusting fan; B, be arranged on fly-ash separator inside passive infrared alarm device survey fly-ash separator inside whether catch fire; C, can send alerting signal to signal acquisition module after passive infrared alarm device detects spark, signal acquisition module is connected with controller, sends off signal by controller to fly-ash separator and dedusting fan.
When use; the present invention is by the monitoring to the spontaneous combustion of fly-ash separator inside; the intelligent sandblast ventilating and purifying air system of controlling; and controlling alarm sandblast ventilating and purifying air system is closed in time; can accomplish that the very first time is to fire alarm; avoid larger economic asset loss, thereby reach the object of protection equipment, safety in production.

Embodiment:
Below in conjunction with drawings and Examples, the invention will be further described.
Label in each accompanying drawing is expressed as follows: 1 blast pipe, 2 pulse backblowing valves, 3 fly-ash separators, 4 passive infrared alarm devices, 5 exhaust ducts, 6 dedusting fans, 7 signal acquisition module, 8 controllers.
A kind of warning device for fly-ash separator spontaneous combustion of the present invention, its difference with the prior art is: described warning device is made up of passive infrared warning device, signal acquisition module and controller, passive infrared warning device is connected with signal acquisition module, and signal acquisition module is connected with controller.Warning device is connected with fly-ash separator, dedusting fan, warning device is arranged in fly-ash separator, passive infrared alarm device is distributed on the inwall of fly-ash separator, the signal acquisition module that each passive infrared alarm device is corresponding with one is connected, each signal acquisition module is all connected with controller, and controller is connected with fly-ash separator, dedusting fan and controls the power-off of fly-ash separator, dedusting fan.
Fly-ash separator is provided with housing, and one end of housing is provided with blast pipe, and the other end is provided with exhaust duct, and a side inwall of housing is provided with pulse backblowing valve, and 5 madial walls of all the other of housing are respectively equipped with 1-20 passive infrared alarm device.Exhaust duct is connected with dedusting fan, and described passive infrared alarm device is spark detection device.
For a using method for the warning device of fly-ash separator spontaneous combustion, its difference with the prior art is: described using method comprises the steps: a, in the time that coating room carries out sandblast operation, successively opens fly-ash separator and dedusting fan; B, be arranged on fly-ash separator inside passive infrared alarm device survey fly-ash separator inside whether catch fire; C, can send alerting signal to signal acquisition module after passive infrared alarm device detects spark, signal acquisition module is connected with controller, sends off signal by controller to fly-ash separator and dedusting fan.
In b step, passive infrared alarm device is distributed on the inwall of fly-ash separator, and the signal acquisition module that each passive infrared alarm device is corresponding with is connected, and each signal acquisition module is all connected with controller.Fly-ash separator is provided with housing, one end of housing is provided with blast pipe, the other end is provided with exhaust duct, one side inwall of housing is provided with pulse backblowing valve, 5 madial walls of all the other of housing are respectively equipped with 1-20 passive infrared alarm device, exhaust duct is connected with dedusting fan, and described passive infrared alarm device is spark detection device.
In force, the fly-ash separator madial wall in sandblast ventilating and purifying air system is installed respectively 2-3 a kind of spark detection device (except pulse backblowing valve installed surface, all the other five faces are installed respectively 2-3 a kind of spark detection device).Then spark detection device is all connected to alerting signal acquisition module, after the signal analysis of warning message acquisition module, transmit an alerting signal to sandblast ventilating and purifying air system controller, thereby allow, controller can according to fly-ash separator inside, whether spontaneous combustion be reported to the police, and shutdown system.The invention has the advantages that the whether spontaneous combustion of fly-ash separator inside of real-time monitoring sandblast ventilating and purifying air system; by the monitoring to the spontaneous combustion of fly-ash separator inside; intelligent control system is reported to the police and is shut down; the very first time is to fire alarm; avoid larger economic asset loss, thereby reach the object of protection equipment, safety in production.
