Description
Technical Field
The invention relates to a control system of a plastic-sintered plate dust remover, the plastic-sintered plate dust remover and a processing technology thereof.
Background
The sintered plate (also called as a plastic plate) refers to a polyethylene powder material, and is actually a thermoplastic combustible white powder. The rigid filter plate is made of polymer material through special sintering process and has PTFE coated surface. The raw materials are all plastics, so the plastic plate is also called as a plastic burning plate. The polytetrafluoroethylene coating on the surface increases the perfect combination of surface filterability and structural strength. The melting point of the polyethylene of the plastic plate is 100-130 ℃, and the low temperature resistance is excellent. The polyethylene plastic sintered plate can still keep good mechanical property at the temperature of minus 60 ℃, but the using temperature is between 80 and 110 ℃. The plastic-sintered plate is a surface filtering method, has high dust removal efficiency, and has the emission concentration of generally lower than 10mg/m < 3 >, and good dust removal effect on fine dust particles; the equipment has compact structure and small occupied area; the rigidity of the plastic plate can not deform, and the steel skeleton is not used, so that the wear is small, the service life is long, and the service life is about 2-4 times of that of the filter bag; the surface and pores of the plastic combustion plate are treated with a chemical resin, the inert resin being completely hydrophobic. It not only does not contain dry dust, but also is not easy to adhere to dust with larger water content. The filter element of the plastic-sintered plate dust remover is of a rigid wave-shaped porous structure, so that the dust removing effect is greatly improved. The plastic plate is a rigid body and is not easy to deform, and the surface and the gaps of the plastic plate are treated by the fluorinated resin, so that the plastic plate is suitable for treating dust with high water content or oil content. Therefore, the plastic-sintered plate dust remover is a good choice for treating dust with high water content or oil content; the price of the plastic-sintered plate dust remover is high, and the same air quantity is about 2-6 times of that of the cloth bag dust remover. Because of the structure and the surface coating, the plastic-sintered plate dust remover can play a good role in the situation that other dust removers cannot be used or are not used well. The plastic plate dust remover is applied to the working condition of larger water vapor. The structure is generally as follows: the dust collector is connected with a front dust collector and a cyclone dust collector through a ventilating duct (selected), the cyclone dust collector (or the front dust collector is directly connected with a pipeline) through a pipeline, an air outlet of the dust collector is connected with a fan, an inlet of the dust collector is provided with a wind shield, large particles fall into a dust hopper through the effect of the wind shield, small particles and water vapor adhere to the surface layer of the dust collector through the filtering effect of the dust collector, a pulse valve (high-pressure pulse back-blowing acting force) is arranged on the upper part of the dust collector, and blown dust falls into the dust hopper of the dust collector.
Although the plastic-sintered plate dust remover is used for treating dust with high water content or oil content, the dust remover and the dust plate on the inner wall of a pipeline are corroded and leaked by long-term operation, so that the exhaust amount of the existing mill flue gas suction hood is small, instant paroxysmal dust raising is not trapped, and the post and the surrounding environment in a mill workshop are polluted. The suction capacity of the suction hood is improved to improve the dust collection effect, and the equipment resistance of the plastic-sintered plate dust remover is reduced as much as possible on the basis of unchanged existing fans. The equipment resistance of the plastic-sintered plate dust remover mainly comes from the body resistance of the plastic-sintered plate, and the low-resistance plate with low resistance, water resistance and oil resistance is selected in the prior art, so that the peeling property of water-containing and oil-containing dust on the surface of the plastic-sintered plate is improved, and the harm that the extremely fine dust enters the plastic-sintered plate body to possibly cause plate blockage is prevented. In the prior art, the dust collection capacity is improved by adopting structural improvement of the air suction cover (namely the air suction cover), for example, a large air suction cover is arranged on the periphery of the upper side of a plurality of air suction covers and is used for capturing the smoke missed by the air suction covers, and then the smoke enters the plastic-sintered plate dust remover through a pipeline. However, on the one hand, a fan needs to be added, and a large fan (because of a large suction hood) cannot meet the comprehensive requirements of some workshops such as a rolling mill area for dust removal.
In addition, in the prior art, the direction of flue gas and the blowing and dropping direction of dust are opposite (as disclosed in patent with the publication number CN 105797506B: a plastic plate dust remover, the plastic plate dust remover comprises a dust removing chamber, wherein the upper part of the dust removing chamber is provided with an opening, a reverse pulse upper cover is arranged at the opening, an air outlet is arranged on the reverse pulse upper cover, a dust-containing air inlet is arranged on the side surface of the dust removing chamber, a dust filter bucket is arranged in the dust removing chamber, the top of the dust filter bucket is communicated with the air outlet, the lower part of the dust filter bucket is provided with a bucket opening, a filtering plastic plate is arranged in the dust filter bucket, a compressed air storage tank is arranged outside the dust removing chamber and is communicated with the top of the dust filter bucket through a compressed air pipe, a plurality of pulse electromagnetic valves are arranged on the compressed air storage tank, a dust collecting funnel is arranged below the dust collecting chamber and is communicated with the dust removing chamber, and the lower end part of the dust collecting funnel is communicated with a dust collecting bucket through a dust discharging valve), so that a large amount of dust falling from the surface of the plastic plate is influenced by air flow from the bottom of the plastic plate and is suspended in the dust remover. The control system of the plastic-sintered plate dust remover for solving the problems plays an important role.

The middle air inlet and the upper air inlet are adopted instead of the bottom air inlet in the prior art, so that the direction of smoke and the falling direction of dust can not generate reverse collision, and the dust falling from the surface of the plastic plate is prevented from being greatly suspended in the dust remover without being influenced by bottom air inlet flow.
The further technical proposal is that the upper air inlet pipeline and the middle air inlet pipeline are provided with on-off valves; the induced draft covers arranged in the workshop area are connected with the fan through pipelines, the induced draft covers are provided with a plurality of induced draft covers, the periphery of each induced draft cover is surrounded by an annular induced draft cover, the annular induced draft covers are also connected with the fan through pipelines, and the pipelines connected with the induced draft covers and the pipelines connected with the annular induced draft covers are provided with regulating valves. The annular air suction cover is additionally arranged on the periphery of the existing air suction cover and used for capturing the smoke omitted by the original air suction cover, and the smoke enters the dust remover through an independent pipeline (an adjusting valve is arranged on the independent pipeline) which is not communicated with the original air suction cover, so that the air quantity of the newly-added annular air suction cover can be adjusted in real time through the adjusting valve, and the comprehensive requirement of a workshop on dust removal is met.
The dust filter chamber is internally and fixedly provided with a plastic burning plate supporting rod, a plurality of plastic burning plates are arranged on the supporting rod, the outside of the upper end of the dust filter chamber is fixedly provided with a compressed air bag, the compressed air bag is connected with a blowing pipe which is opposite to the surface of the plastic burning plate, and the blowing pipe is provided with a pulse valve; the dust collection funnel is provided with a manhole for overhauling.

The further technical proposal is that the blowpipes are provided with a plurality of rows, and each row is arranged at intervals by taking the vertical surface of the plastic-sintered plate as the center line;
the part of the upper air inlet pipeline, which is close to the air inlet chamber, is a section of inclined pipeline, and the inclined direction of the pipeline gradually inclines downwards along the air inlet direction. The blowpipe is arranged left and right in a staggered manner, and compared with the vertical downward arrangement in the prior art, dust particles attached to the surface of the plastic-sintering plate are more beneficial to being blown off.

Although the plastic-sintered plate dust remover is used for treating dust with high water content or oil content, the dust remover is accumulated after long-term operation, the inner wall of an ash bucket of the dust remover is seriously scaled, and the inner wall of the screw conveyor is blocked by scaling, so that the plastic-sintered plate dust remover can be stopped and overhauled off-line and can be normally used. Even because the dust collector and the dust plate on the inner wall of the pipeline are corroded and air leakage, the exhaust amount of the existing rolling mill smoke suction hood is small, instant paroxysmal dust raising is not trapped, and the post and the surrounding environment in the rolling mill workshop are polluted. Meanwhile, the whole collapse possibly caused by serious corrosion of the dust remover can cause serious influence on production. The ventilating duct is changed to be arranged, so that the screw conveyor is arranged to lean against the ventilating duct, the temperature of the flue gas with the temperature of 70 ℃ (or lower than 70 ℃) in the ventilating duct is utilized to properly reduce the humidity of dust, and the problem that a valve is blocked and even a motor is burnt when the dust is discharged due to the high humidity of the dust is avoided.

the die comprises an upper die and a lower die matched with the upper die, wherein a plurality of rows of grooves are formed in the upper die, and protrusions formed by adjacent grooves are obliquely arranged on the top surface of the upper die. The inclined plastic plate is manufactured and matched with the air inlet obliquely downwards, so that dust is easy to fall off the surface of the filter plate and is not influenced by air flow of the air inlet at the bottom to suspend in the dust remover in a large amount.
The invention has the advantages and beneficial effects that: the comprehensive requirements of workshops on dust removal are met, and the flue gas direction and the falling direction of dust can be guaranteed to be consistent and forward.
The control unit controls the opening and closing valves on the middle air inlet pipeline and the upper air inlet pipeline to be opened and closed simultaneously so as to realize simultaneous air inlet filtration and dust removal, or controls the opening and closing valves on the middle air inlet pipeline and the upper air inlet pipeline to be opened and closed intermittently so as to realize that the inlet smoke in different air inlet directions intermittently enter the plastic-burning plate dust remover for dust removal (the mode can avoid that the smoke in different directions simultaneously enters the plastic-burning plate dust remover to be turbulent flow of air).

The middle air inlet and the upper air inlet are adopted instead of the bottom air inlet in the prior art, so that the direction of smoke and the falling direction of dust can not generate reverse collision, and the dust falling from the surface of the plastic plate is prevented from being greatly suspended in the dust remover without being influenced by bottom air inlet flow.
The annular air suction cover is additionally arranged on the periphery of the existing air suction cover and used for capturing the smoke omitted by the original air suction cover, and the smoke enters the dust remover through an independent pipeline (an adjusting valve is arranged on the independent pipeline) which is not communicated with the original air suction cover, so that the air quantity of the newly-added annular air suction cover can be adjusted in real time through the adjusting valve, and the comprehensive requirement of a workshop on dust removal is met.
The blowpipe is arranged left and right in a staggered manner, and compared with the vertical downward arrangement in the prior art, dust particles attached to the surface of the plastic-sintering plate are more beneficial to being blown off.
The ventilating duct is changed to be arranged, so that the screw conveyor is arranged to lean against the ventilating duct, the temperature of the flue gas with the temperature of 70 ℃ (or lower than 70 ℃) in the ventilating duct is utilized to properly reduce the humidity of dust, and the problem that a valve is blocked and even a motor is burnt when the dust is discharged due to the high humidity of the dust is avoided.
