Description
Technical field
The utility model relates to a kind of sack cleaner.
Background technology
Sack cleaner is the filtering type cleaner based on work principle of filter, utilizes organic fiber or inorfil filter cloth by the dust-filtering in gas out, and its operation principle is:
(1) gravitational settling effect---when dusty gas enters sack cleaner, large, the heavy dust of particle settles down under Action of Gravity Field;
(2) warm-up movement effect---the dust (1 micron following) that light weight body is little, with air motion, be in close proximity to air-flow streamline, can walk around fiber, but they are after the collision of gas molecule that is subject to warm-up movement (being Brownian movement), just change the original direction of motion, the touch opportunity that this has just increased dust and fiber, can be captured dust; When filter media fibre diameter is thinner, spacious ground idleness is less, its catch rate is just higher, so be more conducive to dedusting;
(3) inertia force effect---during the unimpeded smooth filter material of gas, can be around fiber and mistake, and larger dust granules is under the effect of inertia force, still by former direction motion, then bumps against and is captured with filtrate;
(4) sieving effect---when the particle diameter of dust compared with the interfibrous spacious ground free time of filtrate or filtrate on gap between dust when large, dust is expired by under detention in the unimpeded smoothness of gas, this be called sieving effect, and when on filtrate, overstocked dust increases, this effect is just obvious.
Sack cleaner is long ago just widely used in each industry part, in order to trap industry dust and the volatile matter of non-bonding non-fiber, catch dust particle and can reach 0.1 micron, there is very high purification efficiency, trap trickle dust efficiency and also can reach more than 99%, and its efficiency is than high.
Traditional sack cleaner structure forms: deduster goes out ash bucket, air inlet and out let, filter chamber (in, lower box), clean room, filter bag and framework (bag cage bone), Manual air inlet valve, Pneumatic butterfly valve, pulse dust cleaning mechanism etc., its dust removal process: dusty gas enters middle part casing by air inlet, from bag, enter in cloth bag, dust is blocked in the surface outside filter bag, the air purifying enters in bag, by cloth bag top, enter upper box again, finally by blast pipe, discharged.
Sack cleaner in the course of the work, along with filter bag surface dust constantly increases, deduster inlet outlet pressure differential also rises thereupon, the efficiency of dust collection of deduster can reduce, and even can affect because of the minimizing of dedusting capacity the production efficiency of whole production line before deduster or cause product quality fluctuation.Therefore complete efficiently in time the core that deashing work is sack cleaner.
The approved product that generally can see on domestic market has following several:
The first: pulsaire collector, its operation principle is: after dusty gas is entered by ash bucket top air inlet, under the effect of deep bead, air-flow upwards flows, and flow velocity reduces, part big dust particle falls into ash bucket because the effect of inertia force is separated.Dusty gas enters middle casing through the filtration, purification of filter bag, and dust is delayed at the outer surface of filter bag, and purified gas enters upper box through filter pocket mouths, by air outlet, is discharged.Its purge mode is pulse jet, and along with filter bag surface dust constantly increases, deduster inlet outlet pressure differential also rises thereupon.When the dedusting time reaches setting value, control system is sent deashing instruction, and soot cleaning system is started working.First magnetic valve is opened after receiving signal immediately, the compressed air of Small diaphragm-piece top air chamber is discharged, due to the stressed change in Small diaphragm-piece two ends, the exhaust passage of being closed by Small diaphragm-piece is opened, and the compressed air of large diaphragm top air chamber thus passage is discharged, the large stressed change in diaphragm two ends, make large diaphragm action, the delivery outlet of closing is opened, and the compressed air in gas bag sprays in bag via efferent duct and injection tube, realizes deashing.After control signal stops, closed electromagnetic valve, Small diaphragm-piece, large diaphragm reset in succession, and winding-up stops.Pulse valve is pulse bag type dust collector critical component, and be the problem that user is concerned about the most its service life.
The second: back-blowing deduster, its operation principle is: the same pulsaire collector of sack cleaner operation principle.Its purge mode is back-blowing mode, in sack cleaner top design a set of blowing device contrary with sack cleaner sack discharge directions, when sack cleaner used after a period of time, bag outer surface aggregation dust, gas penetration resistance increment, air charge rate reduces, now open top part inverse blowing device, gases at high pressure are blown at a high speed in cloth bag and oppositely penetrate cloth bag, the dust of aggregation is cleaned out.Which can be controlled for pulse, interval blowback; The mechanism that also back-blowing device can be designed to rotation works online to realize continuity.
The third: mechanical vibrator formula, the same pulsaire collector of its operation principle.Its purge mode is Patting type, and sack cleaner uses after certain hour, closes intake valve, adopts manual type to pat cloth bag and carries out deashing.Or with mechanism analog, manually pat deashing action and realize mechanical ash removing.
Sum up several sack cleaners of current domestic existence, purge mode is a key factor that determines sack cleaner performance.With purge mode, sack cleaner is classified, basic pattern mainly contains: mechanical rapping cleaning dust mode, the blowback of reverse gas cleaning mode, rapping associating purge mode, pulsating back-blowing purge mode, pulse jetting deashing mode.Low-Pressure Pulse Bag Filter belongs to pulse jetting deashing mode.
In sum, existing deduster technical disadvantages one: highly energy-consuming
Existing pulsed jet cloth filter deashing is all to use compressed air to discharge to carry out deashing, and this mode need to consume a large amount of compressed air, and prepare compressed air, need to consume a large amount of electric energy.
Existing deduster technical disadvantages two: equipment investment expense is high
Pulse dust collector, back-blowing deduster equipment manufacturing cost are high, and concerning using producer, equipment investment can increase, and later stage working service cost is high.The cost that Air Compressor Equipment drops into is equally very high, and the increase of large power-consuming equipment equally also can cause the input of appliance equipment to increase, and use procedure comprises the working service cost, oil consumption cost of air compressor machine etc.
