Description
[technical field]
The present invention relates to deduster, particularly sack cleaner.
[background technology]
Deduster can be divided into polytypes such as centrifugal dust collector, inertia-type deduster, wet scrubber, sack cleaner according to the principle difference of dedusting.The operation principle of centrifugal dust collector is after the dusty gas in the drying roller is extracted out by air-introduced machine, to enter deduster with certain wind speed and rotate, and under action of centrifugal force, dust granule is thrown on the barrel and landing gets off to be accumulated in the bottom of tube.Centrifugal dust collector can collection cut size be the above dusts of 5 μ m, and efficiency of dust collection is generally 75%～85%.The operation principle of inertia-type deduster is after the dusty gas in the drying roller is extracted out by air-introduced machine, enter deduster flip-flop flow direction with certain wind speed, the bulky grain dust drops down separated from the gasly under the effect of inertia force, and the granule dust enters secondary ash collector with gas through ventilation duct; This part dust granule is a fine grained, if recycle, then by conveying worm it is delivered to the import department of hot aggregate elevator, otherwise just draws off from discharge gate after heaping to a certain degree; The resistance and the degree of wear of this deduster are less than centrifugal dust collector, but only are applicable to the dust that collecting granules is bigger; General capture particle diameter is the grit of 40～50 μ m, and efficiency of dust collection is up to 50%, and it often is used with secondary ash collector.But the general collection cut size of wet scrubber is the grit of 0.5 μ m, and efficiency of dust collection is more than 95%, but needs configuration cycles water sedimentation pond, and floor space is big, and dust can not be recycled, and also has acidic materials---the handling problem of mud.Sack cleaner is a kind of high-effective dust-removing device, utilize organic fiber or inorfil to make cloth bag, dust in flue gas is leached, in order to industrial dust and the volatile matter that captures non-bonding non-fiber, catch dust particle and can reach 0.1 micron, sack cleaner has very high purification efficiency, capture trickle dust efficient and also can reach more than 99%, and its efficient is more stable.
Sack cleaner is divided into two Room with cloth bag, under the swabbing action of blower fan, ash-laden gas enters casing, flue gas is by dispersion flows under cutting of deflection plate kept off, and dusty gas enters (filter bag is equipped with skeleton) in the filter bag from each filter bag outside, under the effects such as filtration, impact, interception, diffusion and electrostatic attraction of filter bag, micronic dust is attached between the filter cloth slit, thereby dust is separated from flue gas, and purifies back gas by cloth bag, enters atmosphere from the inboard.The dust that sticks on the cloth bag increases gradually, cause the gas pressure difference of cloth bag medial and lateral to increase thereupon, after pressure reduction reaches setting value, pulse valve is opened, the inboard high-voltage pulse compressed air that feeds automatically of cloth bag is shaken off dust, fall the dust of bottom and discharge, can be used as the breeze utilization after the recovery through conveying worm.During sack cleaner work, filter bag is divided into the N group, N-1 group filter bag is arranged all the time in work, one group of filter bag for guaranteeing the filtration of filter bag, must keep certain pressure reduction between the Purge gas after ash-laden gas and the filtration at deashing, therefore on the sack cleaner difference gauge is housed, when the pressure reduction of one group of filter bag is excessive, shows that the filter bag dust stratification is more, at this moment pulse valve is opened, be blown into the pulse compression air, dust is shaken off, pressure reduction is too small, show the existing damage of filter bag, at this moment need change filter bag.The operation principle of dust settling pocket technique is to utilize the gravitational settling effect, and when dusty gas entered sack cleaner, big, the heavy dust of particle settled down under the gravity effect, and the effect of this and expansion chamber is identical; The sieving effect, when the particle diameter of dust than the interfibrous space of filtrate or filtrate on gap between dust when big, dust is out-of-date promptly by under the detention in air communication, this promptly is called the sieving effect, when accumulating dust on the filtrate and increase, this effect is just significantly got up; The inertia force effect, during the air communication filter material, can be around fiber and mistake, and bigger dust granules is under the effect of inertia force, still by former direction motion, satisfy and bump against with filtrate and be hunted down; With the warm-up movement effect, the dust that the light weight body is little (below 1 micron) with air motion, is in close proximity to the air-flow streamline, can walk around fiber.But they just change the original direction of motion after the collision of the gas molecule that is subjected to doing warm-up movement (being Brownian movement), the touch opportunity that this has just increased dust and fiber can be hunted down dust.When the filtrate fibre diameter is thin more, voidage is more little, its capture rate is just high more, so help dedusting more.
Current, sack cleaner all adopts dull and stereotyped shell and dull and stereotyped demarcation strip, because the characteristics of sack cleaner are, casing is in service in filtration of dirt gas and deashing, bear 6000～14000Pa pressure, so set up many reinforced steels on the flat board, the automation high efficiency production of bag-feeding deduster has been brought very big difficulty like this; Particularly China lacks mineral resources, has greatly wasted raw material and set up a lot of reinforced steels, has also increased the cost of material of enterprise; And set up a lot of reinforced steels and correspondingly increase a lot of welding jobs later on again, increased the production cost of enterprise; And also be easy to generate welding deformation in the welding process, the part distortion is difficult to control and repairs, and has so just influenced the presentation quality of product.
So, how to adopt effective method to reduce raw material and production cost, and realize that the automation high efficiency production of sack cleaner becomes the important topic of deduster manufacturing enterprise research.
