Abstract
The utility model provides a thermal power factory fortune coal measures is dust collector of bunker bay removal dummy car all which characterized in that: set up the dust removal body on moving platform, moving platform is connected with the dummy car, and dummy car discharge opening raise dust point department sets up the gas collecting channel, the gas collecting channel set up flagging adjustable sealed soft curtain all around, be connected with the dust absorption pipe with the dummy car side, dust absorption pipe one end and gas collecting channel intercommunication, dust tube is connected to the other end and dust removal body intercommunication below the dust removal body. The utility model discloses get into the dust removal body with dirty gas by dust absorption pipe, the filter bag of dust in by the body that removes dust blocks the separation, and the gas after the purification is discharged through the fan again. Increase when this internal filter bag surface dust that removes dust, when the resistance value reached the predetermined value, pressure sensor signals began the operation by PLC automatic control's pulse soot blower system, will shake off attached to the dust on the filter bag, and the warp density is sealed a dust tube and is directly fallen back in the coal bunker. Dummy car is equipped with one and removes the dust removal body, and dust removal effect can reach and contain the total dirt of dust content in the air of workplace and be not more than 2mgNm3, satisfies existing national regulation requirement.
Description
Technical field
This utility model belongs to the technical field of thermal power plant fortune coal measures system bunker bay dust removal design, especially relates to the dust pelletizing system of thermal power plant mobile dummy car.
Background technology
The bunker bay dosing device of thermal power plant fortune coal measures system uses mobile dummy car, and it runs on the track of belt conveying machine support, and track runs through whole bunker bay.Dummy car is during mobile unloading coal, and around discharge port and the coal bunker top substantial amounts of impact diffussion of dust of generation, in bunker bay, makes whole bunker bay environment receive severe contamination, affects operator's work.Cleaner unit need to be fixed on bunker bay ground by the dedusting method of conventional fixed-type cleaner unit, and it hinders the running space of unloading coal that dummy car moves.Thus result in fixed cleaner unit without fully can arrangement space, it is impossible to meet dust removing effects related request.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of relatively reliable safe dedusting method for the mobile dummy car mode of unloading coal, and makes bunker bay room air dust content meet existing national regulation requirement.
For solving above-mentioned technical problem, the present invention provides the dust arrester of a kind of thermal power plant fortune coal measures system bunker bay mobile dummy car, it is characterized in that: face arranges dedusting body on a mobile platform, mobile platform is connected with dummy car, arranges gas skirt at dummy car discharge port airborne dust point, and the surrounding of gas skirt arranges the soft curtain of sagging adjustable sealing, it is connected with dummy car side and has sweep-up pipe, sweep-up pipe one end connects with gas skirt, and the other end connects with dedusting body, connects ash tube below dedusting body.
Dedusting body uses pulsed jet cloth filter.
Ash tube part is also adopted by gas skirt, and surrounding arranges the soft curtain of sagging sealing.
Mobile platform is by assisting steel platform and road wheel to form, and road wheel diameter is Tong Bu with former dummy car road wheel.
By Flange joint between mobile platform and dummy car, when needing monomer to overhaul, detachably separate, do not interfere with the operation of dummy car.
This utility model utilizes dummy car orbit Design mobile platform, dedusting body is arranged on mobile platform, by the sweep-up pipe between connection dummy car and dedusting body, dusty gas is entered dedusting body by sweep-up pipe, dust is stopped separation by the filter bag in dedusting body, and purified gas is discharged through blower fan again.When this internal filter bag surface dust of dedusting increases, and when Resistance Value reaches predetermined value, pressure transducer sends signal, PLC the impulse soot blowing system automatically controlled brings into operation, and will be attached to the dust on filter bag and shakes off, and sealed ash tube directly drops back in coal bunker.One dummy car is equipped with a movable dust removal body, and dust removing effects can reach the total dirt of dust content in workplace air and be not more than 2mg/Nm3, meet existing national regulation requirement.

Detailed description of the invention
With reference to Fig. 1, Fig. 2, face arranges pulsed jet cloth filter on a mobile platform, mobile platform is connected with dummy car, band is set at dummy car discharge port airborne dust point and seals the gas skirt of soft curtain, it is connected with dummy car side and has sweep-up pipe, sweep-up pipe one end connects with gas skirt, and the other end connects with dedusting body, connects ash tube below dedusting body.
Dedusting body uses pulse bag type dust collector, comprises filter bag, blower fan, Pulse anti-blow device, air compressor, intelligent control box etc..Dusty gas is entered pulsed jet cloth filter by sweep-up pipe, and dust is stopped separation by filter bag, and purified gas is discharged through blower fan again.When filter bag surface dust increases in cleaner unit, and when Resistance Value reaches predetermined value, pressure transducer sends signal, PLC the impulse soot blowing system automatically controlled brings into operation, will be attached to the dust on filter bag and shake off, sealed ash tube directly drops back in coal bunker.Equipment can carry the required compressed air source unit of cleaner unit work, it is possible to on-the-spot offer.
Dedusting body is arranged on mobile platform, and mobile platform is by assisting steel platform and road wheel to form, and road wheel diameter is Tong Bu with former dummy car road wheel, and the size of gauge and platform determines according to field condition.By Flange joint between mobile platform and dummy car, when needing monomer to overhaul, detachably separate, do not interfere with the operation of dummy car.
In order to effectively collect dusty gas, gas skirt is set discharge port is wrapped in centre.In gas skirt, surrounding arranges the soft curtain of sagging adjustable sealing, remains to keep the sealing of coal bunker mouth during dummy car walking.Simultaneously in order to avoid ash tube fall ash time airborne dust secondary pollution, ash tube part is also adopted by gas skirt, and surrounding arranges the soft curtain of sagging sealing, is wrapped up wherein by ash tube.Observing coal breakage or the ash situation that falls for the ease of operator, gas skirt appropriate location sets observation panel, and it is convenient to open, and does not affect the operation of operator and passes through.
In actual motion, in order to not affect the travel distance of dummy car, meet coal bunker holds coal capcity, needs original operation track to carry out line space freestone in fact, needs advancing the track, to ensure the operation of Mobile type dust-collector in the case of necessity.
This dust arrester processes air quantity according to 10000 ~ 12000m3/ h adjusts, and the total power consumption of every table apparatus is about 15kW/380V (without air compressor machine), gross weight about 3.5t(and comprises mobile platform).Pulsed jet cloth filter is interlocked with dummy car, and advanced startup hysteresis is shut down.
