Abstract
The invention discloses an air-cannon multipoint oscillation dust removing device for a bag-type dust collector. An air-cannon electric control device of the device is connected with an electromagnetic directional valve which is arranged on a rear cover of an air-cannon quick opening valve and communicated with the air-cannon quick opening valve. The electromagnetic directional valve and the air-cannon quick opening valve are connected with an air-cannon storage air cylinder through an internal channel respectively. A compressed air inlet pipe is connected with the electromagnetic directional valve. The air-cannon quick opening valve is communicated with horizontal pipes and vertical pipes in turn through pipelines. Conical impact air openings are formed on the vertical pipes. The vertical pipes are arranged between bags and have length which is identical with or a little shorter than the length of the bags. The conical impact air openings are reserved at different length positions of all the vertical pipes, a plurality of conical impact air openings are reserved at the length positions, and each conical impact air opening is formed in a manner of facing the bag transversely. The air-cannon multipoint oscillation dust removing device for the bag-type dust collector provided by the invention has the advantages of large bag oscillation amplitude, good dust removing effect and long bag service life.
Description
Technical field:
The present invention relates to a kind of deashing device of deduster, particularly a kind of air-cannon multipoint oscillation deashing device that is used for sack cleaner.
Background technology:
In the deduster field, sack cleaner has its distinct advantages as dry method dust.Because its action principle is to contain dust gas directly through the cloth bag filtration, dust removing effects can reach more than 90%.Particularly,, just can effectively filter out as long as the slit of cloth bag is enough little to the dust of ultra-fine granularity.Dedusters such as this is centrifugal to other, inertia-type, dynamical type are incomparable, and certainly, wet dedusting also can be washed molecule off, but the mud conditioning in the wet method has great difficulty, has also limited its scope of application.
Though the fiber bag precipitator effect is good, be exactly to want timely deashing, because the cloth bag slit can be blocked by the dust particle pointing gradually in the process of filtering, the resistance that ventilates increases, the treating capacity of air descends.So how to keep sack cleaner all the time certain filter effect can be arranged, the method for deashing just becomes key issue.
From the ash removal method of existing sack cleaner, mainly contain several types of mechanical oscillation, back blowing machine formula, pulse backblowing wind, again from the cloth bag structural analysis; It mainly is elongated cylindrical; The lower end is fixed, and the upper end resilient suspension is closely arranged to save the space; According to handling air quantity decision filter area, just cloth bag quantity.Have single chamber that multicell is also arranged, continuous operation is main with multicell, and interrupter duty is main with single chamber then.Can be divided into online ash removal and off-line ash-clearing again according to the deashing state.And these ash removal methods all have a drawback, are exactly the total length that the application point of deashing can not be taken into account cloth bag.If the cloth bag overmatter, like the back blowing machine formula, effect is quite a lot of on the edge, and more past centre effect is just poor more.The existing pulsed sack cleaner of using morely, magnetic valve is frequently opened, and toward the interior frequent qi of chong channel ascending adversely of cloth bag, can more and more decay, and just almost do not had the deashing effect from air inlet cloth bag at a distance by qi of chong channel ascending adversely pressure through magnetic valve for compressed air.Like this, just increasing to the air intake resistance of blower fan after sack cleaner uses a period of time, when the effect of deashing too hour, just must clean cloth bag and perhaps change cloth bag.
Summary of the invention:
The purpose of this invention is to provide a kind of greatly to the cloth bag oscillation amplitude, ash-removal effect is good, makes the cloth bag long multipoint oscillation deashing device that is used for sack cleaner service time.
Technical scheme of the present invention is: a kind of air-cannon multipoint oscillation deashing device that is used for sack cleaner.The electrical control gear of its air bubble is connected with solenoid directional control valve.Solenoid directional control valve is contained on the bonnet of air bubble quck-opening valve and has passage to communicate with the air bubble quck-opening valve, and solenoid directional control valve is connected with the air bubble air tank through the inner passage respectively with the air bubble quck-opening valve.Compressed air inlet pipe is connected with solenoid directional control valve.The air bubble quck-opening valve communicates through managing logical linking to each other with horizontal tube.Horizontal tube links to each other with vertical tube and communicates.Offer taper on the vertical tube and impact gas port.
Described air bubble air tank, air bubble quck-opening valve, electromagnetic switch air valve and horizontal tube all are contained in the top of sack cleaner.
It is same or slightly shorter that described vertical tube is contained between each cloth bag the length of its length and cloth bag.
Described taper is impacted gas port and is opened on the different extension position of each vertical tube.Have a plurality of tapers on the different extension position of each vertical tube and impact gas port, each taper impact gas port all is horizontal for the cloth bag installation.
Ash removal method of the present invention is: the electromagnetic switch air valve is a normally open, and the air bubble quck-opening valve is in closed condition.Compressed air is inflated to the air bubble air tank through compressed air inlet pipe, electromagnetic switch air valve.The electrical control gear indication is closed the electromagnetic switch air valve and is opened the air bubble quck-opening valve simultaneously when the needs deashing.Air bubble air tank compressed air outwards impacted and formed shock wave with great speed through air bubble quck-opening valve, horizontal tube, each vertical tube and each taper impact gas port and rushes at each cloth bag this moment; Because the air bubble impulsive force is big with the diffusingsurface angle is little and taper is impacted characteristics such as gas port is many and made each cloth bag on total length, all receive thermal agitation because this deashing device is horizontal with air bubble on the cloth bag length direction, multiple spot to cloth bag vibrate, deashing.So the cloth bag oscillation amplitude is big, ash-removal effect is good, and service time is long.The electrical control gear indication is opened the electromagnetic switch air valve and is closed the air bubble quck-opening valve simultaneously after deashing is accomplished.This moment, compressed air was inflated to the air bubble air tank through compressed air inlet pipe, electromagnetic switch air valve.Accomplish a deashing action like this.
Advantage of the present invention has provided a kind of big to the cloth bag oscillation amplitude, and ash-removal effect is good, makes the cloth bag long multipoint oscillation deashing device that is used for sack cleaner service time.
