8th, dust pelletizing system

This system is mainly made of two sets of cleaning shafts, deduster 11, wind turbine 6, air hose 3.Deduster is efficient and environment-friendly type Filter cartridge dust remover, efficiency of dust collection 99.9% meets the requirement of GB16297-1996 " atmosphere pollution comprehensive discharge standard ", and accords with GBJ14-93 Industrial " three Waste " discharge standards are closed, makes the air containing dust, can be directly discharged in air after dedusting, no Need cleaning equipment.

It is that my company absorbs domestic and international deduster advanced technology that ZLC series, which sinks streaming filter cartridge dust remover, autonomous to research and develop High-efficiency dust remover of new generation.There is low voltage difference, efficient.

Rational air inlet design makes the distribution of air flow in body more uniform, and reduce gas-flow resistance, in normal operation Under state, the pressure drop between air ports flange only has 300Pa or so.Optimum filtration wind speed is 0.4~0.45 m/min.

Filter cartridge dust remover has the features such as small, running resistance is small, good dedusting effect, and efficiency of dust collection reaches 99.9%, base This realization " 0 " is discharged.

Deduster uses import cartridge type filter.The filter selects Japanese Utility filtrate, its main feature is that super one layer The super thin fiber of submicron order is adhered on general filtrate, is arranged between the fiber of adhesion layer closely, gap is only bottom The 1% of fiber.

Filter cylinder is manufactured by unified standard, using quick connection, is made filter cylinder dismounting very convenient, is alleviated worker's manual labor Intensity improves working condition.

2nd, structure and working principle

1st, structure

ZLC series filter drum type precipitator is by flue-dust retainer, babinet, wind turbine, air hose, filter cylinder, pulse valve, pulse instrument, stent etc. Composition.

The filter cylinder makes the cylindrical shape of folding, outer diameter 330mm, internal diameter 220mm, the high 1000mm of cylinder in structure.One mark Quasi- filter cylinder filter area is 13m², and the filter area of the fiber bag precipitator of similary build only has 0.7m²。

The super thin fiber of one layer of submicron order is adhered on general filtrate, is arranged between the fiber of adhesion layer closely, Gap is only the 1% of bottom fiber.Most of submicron order grit can be blocked in filtrate outer surface by minimum sieve pore, make it It cannot enter inside bottom fiber.Therefore the dust layer of good air permeability just can be formed in the early stage, it is made to keep low-resistance, efficiently.Due to Dust cannot go deep into inside filtrate, therefore have the characteristics that low-resistance, convenient for deashing.This feature is that bag filter can not compare 's.

2nd, operation principle

（1）Deduster

In normal operation, dust laden air enters deduster from dust remover roof air inlet and passes through filter cylinder, dust by every From and accumulate in filter material outer surface, and clean air then enters cleaned air room by the center of filter cylinder, most afterwards through deduster Under（Side）The air outlet discharge in face.

When cleaning filter cylinder, time sequence controller driving pulse valve manipulates the membrane valve on compressed air jet pipe, high pressure Compressed air is sprayed by jet pipe, removes the dust of filter cylinder.The dust fallen then with downward air-flow, is fallen into dust arrester.

Heavy streaming filter cartridge dust remover is the deduster that efficiency of dust collection is improved using downlink air-flow.

（2）Electromagnetic impulse valve（DMF-Z）

Electromagnetic impulse valve is divided into former and later two gas chambers by diaphragm, and when connecting compressed air, compressed air passes through throttle orifice Into rear gas chamber, diaphragm is close to the delivery outlet of valve by rear gas chamber's pressure at this time, and electromagnetic impulse valve is in "Off" state.

The electric signal of pulse moves solenoid valve armature, and valve rear gas chamber venting chambers deflation stomata is opened, and rear gas chamber is lost rapidly It presses, is moved after diaphragm, compressed air is sprayed by valve delivery outlet, and electromagnetic impulse valve is in " unlatching " state.

Pulse electrical signal disappears, and electromagnetic impulse valve armature resets, and rear gas chamber's deflation bore closure, rear gas chamber's pressure rise makes film Piece is close to valve outlet, and electromagnetic impulse valve is in "Off" state again.

The machine is roller-way conveying-type high-performance impact cleaning device, and rollgang is driven by speed regulating motor in scale removal process Workpiece is sent into cleaning chamber when casting area, the workpiece each face in the whole body by the different directions from space structure eight impeller heads The strike and friction of the intensive strength bullet of assembly, oxide skin and dirt thereon come off rapidly, and steel surface obtains certain thick The glossy surface of rugosity, while workpiece is due to by intensive brute force attack, eliminating workpiece stress, workpiece is avoided to deform.

In scale removal process, scatter the ball dirt mixture to get off and come together in elevator lower casing again through chamber body feeding screw conveyer Boosted machine, conveyer reach separator, generate ball dirt waterfall through separator, are blown by air port and raise removing dust, dry after separation Net bullet falls into separator hopper, is dished out through bullet transport system by impeller head.

It is driven from separator, the indoor dirt in air of cleaning by ventilation blower, passes through air duct pipe-line system, filter cartridge dust remover Dedusting, efficiency is up to 99.9%, and air is discharged into air after purification, and particle dust is captured collection.

The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form Limitation, although the utility model has been disclosed with preferred embodiment as above, be not limited to the utility model, it is any ripe Professional and technical personnel is known, is not being departed from the range of technical solutions of the utility model, when in the technology using the disclosure above Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as being without departing from technical solutions of the utility model Hold, any simple modification, equivalent change and modification that foundation the technical essence of the utility model makees above example, still Belong in the range of technical solutions of the utility model.
