Description
Technical field:
The utility model relates to the deduster field, relates in particular to a kind of sack-duster pulse drainage deashing device.
Background technology:
The pulse dust cleaning mode is be most widely used in the present sack cleaner deashing a kind of, and it can be divided into air box impulse deashing and row spray pulse dust cleaning dual mode:
Air box impulse deashing, its characteristic are that the filter bag with some is combined as a casing and forms an air chamber, and each air chamber only carries out deashing with one or two pulse valve to the filter bag in the air chamber.When deashing, air chamber need be isolated (off-line), this moment is owing to exist high negative in the filter air chamber, filter bag in the isolation air chamber inwardly shrinks under the usefulness of negative pressure and is crushed, pass through pulse valve then compressed gas spirt card top gas tank, pour the filter bag that is installed under the card after in casing, expanding, filter bag is subjected to the expansion outwards shake of the strong row of expansion generation rapidly from top to bottom of gas, thereby the dust releasing that sticks under the effect of this shake on the filter bag is finished the deashing task.The advantage of this purge mode is: every air chamber only needs 1～2 pulse valve; Winding-up pipe and Venturi tube need be installed, and simple in structure, filter bag is changed convenient.Its shortcoming is: winding-up strength and tolerance that can not utilize the perforate of winding-up pipe to regulate every capable filter bag, therefore may cause deashing non-uniform phenomenon in the air chamber and cause local filter bag damage.The most compressed gas deashing energy may directly be jetted and be slatterned at last gas tank inwall, and the compression body consumption is big, and cost increases.
Row spray pulse dust cleaning is that the winding-up pipe is set above the every capable filter bag of sack cleaner, on each winding-up pipe several injection holes is arranged, each injection hole, and each injection hole is aimed at a filter pocket mouths.During deashing, inject filter bag by the jet-action of injection hole from the air pulse of pulse valve ejection, and the gas around introducing, make filter bag produce vibration, the effect that adds the superinverse air-flow is got off the dust releasing on the filter bag, thereby finishes deashing process.In order to increase ash-removal effect, generally all can in filter bag, add Venturi tube.It can overcome the uneven phenomenon of deashing in the gas tank winding-up air chamber, but because in upper box pure qi (oxygen) case, equipped a whole set of winding-up pipe, guarantee to induce tolerance and guarantee ash-removal effect to combine with each filter bag Venturi tube suitable for reading, this has also brought a lot of troubles for operation and maintenance: when filter bag is changed, owing to fixing winding-up is managed, the Luo bolt corrosion of Venturi tube is difficult to dismounting, waste time and energy; Jetting pressure height or the assembling of winding-up pipe are bad to be to be prone to high velocity air with the filter bag phenomenon of blowing brokenly suitable for reading; Because the existence of Venturi tube weakens filter bag place suitable for reading ash-removal effect.
The utility model content:
The purpose of this utility model provides a kind of sack-duster pulse drainage deashing device, and it adopts action of low-voltage pulse to add the mode of drainage, and the deashing air consumption is few, and is simple in structure, the operation and maintenance facility.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises air chamber, inlet, the primary air pulse valve, lift valve, air outlet, sealing plate, the dirt bag, it also comprises the drainage pulse valve, drainage pulse pipe and nozzle, air chamber upper cavity arranged outside has the drainage pulse valve, primary air pulse valve and lift valve, the primary air pulse valve is arranged on the porch, the drainage pulse valve links to each other with the drainage pulse pipe, the drainage pulse pipe penetrates air chamber upper cavity inside, drainage pulse pipe lower end is provided with a plurality of nozzles, the nozzle below is provided with the dirt bag, air outlet is arranged on a side of air chamber lower chamber, and be separated by by sealing plate and epicoele, lift valve links to each other with sealing plate.
Operation principle of the present utility model is: when the dirt bag in the air chamber needs deashing, the lift valve action, sealing plate is isolated the passage between upper chamber and the air outlet, this moment, this air chamber was in off-line state, the dirt bag inwardly shrinks under the effect of filter air chamber negative pressure, primary air pulse valve and drainage pulse valve are opened simultaneously, because the drainage pulse pipe is very thin, air pressure is bigger than main pulse air-flow again, therefore the drainage air-flow sprays rapidly, the drainage air-flow will drive its surrounding air and flow in the dirt bag, under the high speed of drainage air-flow drives, the main pulse air-flow also enter more rapidly the dirt bag and in motion at the bottom of the bag owing to be subjected to the littler speed of its resistance of draw of drainage air-flow higher, the dirt bag is under the effect of this high speed main pulse air-flow, from top to bottom expand rapidly and then shrink rapidly, stick to the dust releasing on the dirt bag under this strong vibration effect, ashman finishes.
The utility model has the advantages that: on the basis that guarantees the jetting deashing effect, reduce the deashing air consumption, operation and maintenance is convenient, and the deduster maintenance is convenient.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
With reference to Fig. 1, this specific embodiment is by the following technical solutions: it comprises air chamber 1, inlet 2, primary air pulse valve 4, lift valve 5, air outlet 6, sealing plate 7, dirt bag 10, it also comprises drainage pulse valve 3, drainage pulse pipe 8 and nozzle 9, air chamber 1 upper cavity arranged outside has drainage pulse valve 3, primary air pulse valve 4 and lift valve 5, primary air pulse valve 4 is arranged on inlet 2 places, drainage pulse valve 3 links to each other with drainage pulse pipe 8, drainage pulse pipe 8 penetrates air chamber 1 upper cavity inside, drainage pulse pipe 8 lower ends are provided with a plurality of nozzles 9, nozzle 9 belows are provided with dirt bag 10, air outlet 6 is arranged on a side of air chamber 1 lower chamber, and be separated by by sealing plate 7 and epicoele, lift valve 5 links to each other with sealing plate 7.
The operation principle of this specific embodiment is: when the dirt bag 10 in the air chamber 1 needs deashing, lift valve 5 actions, the passage that sealing plate 7 is isolated between upper chamber and the air outlet 6, this moment, this air chamber was in off-line state, dirt bag 10 inwardly shrinks under the effect of filter air chamber negative pressure, primary air pulse valve 4 and drainage pulse valve 3 are opened simultaneously, because drainage pulse pipe 8 is very thin, air pressure is bigger than main pulse air-flow again, therefore the drainage air-flow sprays rapidly, the drainage air-flow will drive its surrounding air and flow in the dirt bag, under the high speed of drainage air-flow drives, the main pulse air-flow also enter more rapidly the dirt bag and in motion at the bottom of the bag owing to be subjected to the littler speed of its resistance of draw of drainage air-flow higher, the dirt bag is under the effect of this high speed main pulse air-flow, from top to bottom expand rapidly and then shrink rapidly, stick to the dust releasing on the dirt bag under this strong vibration effect, ashman finishes.
The advantage of this specific embodiment is: on the basis that guarantees the jetting deashing effect, reduce the deashing air consumption, operation and maintenance is convenient, and the deduster maintenance is convenient.
