Description
Technical field
The present invention relates to a kind of rotary kiln lime production line sack cleaner high temperature automatic safety device, realize under the improper condition of production automatic protection the sack cleaner cloth bag.
Background technology
At present; In the rotary kiln lime production technology, sack cleaner is a visual plant realizing that environmental protection is produced, but because the undesired situation of producing; The cloth bag of the as easy as rolling off a log damage sack cleaner of too high EGT; Its interior high temperature range of simultaneously different cloth bags is different, and traditional guard method is artificial according to the sack cleaner inlet temperature, and manual adjustments sack cleaner inlet is joined cold blast sliding valve.Shortcoming: 1, reaction speed is slow, can not effectively implement protection to sack cleaner; 2, labour intensity is big.
Summary of the invention:
In order to overcome the shortcoming of prior art, the present invention provides a kind of sack cleaner high temperature automatic safety device.It can realize in time regulating the aperture that the sack cleaner inlet is joined cold blast sliding valve, protecting cloth bag dust collector according to the requirement of different sack cleaners.
The present invention solves the technical scheme that its technical problem takes: it comprises:
Industrial computer: be installed on the operating desk in control room; Be connected with Programmable Logic Controller (PLC) in the regulator cubicle through EPA; Show sack cleaner inlet waste gas actual temperature, sack cleaner inlet exhaust gas flow, join the actual aperture of cold blast sliding valve, and set sack cleaner different temperature protection value according to producing actual needs;
Regulator cubicle: air switch, Programmable Logic Controller (PLC) and analog quantity input thereof, output module are installed in the regulator cubicle; The analog module of said PLC connects the sack cleaner inlet temperature respectively and detects thermal resistance, joins cold blast sliding valve aperture feedback signal; The PLC analog output module connects the electronic type quick adjustment and joins cold blast sliding valve; Regulate cold flow, the cloth bag of protecting cloth bag dust collector is not damaged;
Temperature detection thermal resistance: detect the sack cleaner inlet temperature;
Flow detector: detect sack cleaner inlet exhaust gas flow;
Join cold blast sliding valve with the electronic type quick adjustment: regulate sack cleaner import cold flow, protection deduster cloth bag exempts from damage.
The present invention can realize in time regulating the aperture that the sack cleaner inlet is joined cold blast sliding valve according to the requirement of different sack cleaners, the protecting cloth bag dust collector is in time closed the air distribution valve simultaneously under the production normal condition, reach purpose of energy saving.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Accompanying drawing is a calcspar of the present invention.
The specific embodiment
Shown in accompanying drawing, the present invention includes industrial computer, regulator cubicle (distribution and PLC system), temperature detection thermal resistance, exhaust gas flow checkout gear and electronic type fast-acting modulator valve.
Described industrial computer is installed on the operating desk in control room; Be connected with Programmable Logic Controller (PLC) in the regulator cubicle through EPA; Show sack cleaner inlet waste gas actual temperature, sack cleaner inlet exhaust gas flow, join the actual aperture of cold blast sliding valve, and set sack cleaner different temperature protection value according to producing actual needs.
Described regulator cubicle is installed in switchgear house; Air switch, Programmable Logic Controller (PLC) and analog quantity input thereof, output module are installed in the cabinet; The analog module of said PLC connects the sack cleaner inlet temperature respectively and detects thermal resistance, joins cold blast sliding valve aperture feedback signal; The PLC analog output module connects the electronic type quick adjustment and joins cold blast sliding valve, regulates cold flow, and the cloth bag of protecting cloth bag dust collector is not damaged.
Described temperature detection thermal resistance uses four; Be installed in the different azimuth of sack cleaner inlet duct respectively; Be used to detect the EGT (joining each two of cold blast sliding valve front and back) of pipeline different piece, prevent simultaneously to produce misoperation owing to the fault of indivedual thermal resistances.
Described gas flow checkout gear is installed in the sack cleaner inlet; After the electronic type quick adjustment is joined cold blast sliding valve; Be used to detect sack cleaner inlet exhaust gas flow under the normal condition; Be used to detect the total flow of joining cold wind and waste gas under the improper situation, join the cold blast sliding valve aperture and regulate parameter is provided for the PLC system provides.
Described electronic type quick adjustment air distribution valve is installed in on-the-spot sack cleaner inlet, is convenient to realize that quick adjustment joins cold blast rate.
Described PLC adopts the S7-300 of Siemens Company.
According to the technological parameter of production requirement and different sack cleaners, on industrial computer, set sack cleaner temperature protection setting value, from four temperature detection thermal resistance signal sampled values entering PLC systems at scene; In the PLC system, be converted into actual temperature value; Through identification judge confirm whether EGT has trend of rising, compare with setting value; If exceed reasonable deviation; Then go out the aperture that electronic type is joined cold blast sliding valve fast, drive the electronic type quick adjustment by PLC system output real-time regulated signal and join cold blast sliding valve, remind the technological operation personnel to produce simultaneously and be improper situation according to the exhaust gas flow calculated signals.After the normalization along with production status, the aperture that cold blast sliding valve is joined in automatic adjusting is until closing.Can significantly improve operating efficiency through the present invention, reduce the spoilage of equipment, energy savings and reduction labour intensity.
