Description
Technical field
The utility model relates to the core filter element in the centrifugal purifier of administering the atmospheric fallout particle contamination, refers to a kind of radial radiation-type rotational filter screen disc particularly.
Background technology
In the process of administering air environmental pollution, the seizure of micronic dust particle floating thing is a great problem that perplexs the scientific research personnel for a long time always.The generation of micronic dust particle mainly comes from following several form in the atmosphere: the one, derive from the cooking fume in family kitchen and food and drink hotel, and these have a full-bodied volatility material is lasting to the pollution that atmosphere caused; The 2nd, derive from the waste gas that various manufactories, processing factory, chemical plant discharge, contain a large amount of micronic dust particle harmful substances in these waste gas, unprocessedly just directly be discharged in the air, very big to the injury that human respiratory caused; The 3rd, derive from the ventilation air interchange system of megastore, enterprises, its operation principle is that the direct suction of outdoor fresh air is indoor, if contain micronic dust particle floating thing in the outdoor air, then room air just can be subjected to infringement inconspicuous, and chronic pollution year in and year out is even more serious to the infringement of health.
Along with the enhancing day by day of social enviroment protection consciousness, people are also more and more higher to the requirement of self and surrounding enviroment, and the control of atmospheric fallout particle contamination is very urgent.At present, the device that is used for the collection and treatment of micronic dust particle mainly contains electrostatic precipitator, fiber bag precipitator, centrifugal dust collector etc.
The principle of electrostatic precipitator is to utilize between the high-field electrode formed magnetic field to adsorb the micronic dust particle.Because high-field electrode is easy to be stained with dust, cause electric-field intensity to reduce, its purification efficiency is descended rapidly.As keeping electric-field intensity, then need frequently to take apart cleaning, maintenance workload is big, and maintenance requires high, and the frequent replacing of battery lead plate also causes cost to increase.
The operation principle of fiber bag precipitator be when dust-contained airflow when the filter bag, tiny gas molecule is by being stained with the filter cloth space of dust layer, and oarse-grained dust be blocked by, and under the gravitational settling effect, drop in the ash bucket.Its advantage is that initial dust removal efficiency is higher, but when the filter cloth surface dust is constantly thickeied, resistance continues to increase, when the space constantly reduces, air-flow is difficult to pass through, dust layer runs up to a certain degree, must utilize various purge modes to empty filter bag.Its operating cost is higher, and maintenance workload is big.
The operation principle of centrifugal dust collector is the gyration by gas, and the grit in the gas is applied centrifugal force, thereby grit is separated from air-flow, and by gravitational settling in ash bucket, clean gas is then discharged from top outlet.Be characterized in that simple in structure, cost and operating cost are low, easy to maintenance, its pressure loss is generally 500～1500Pa, is applicable to the dust of removing greater than 5 μ m.But still there is following defective in it: at first, be not easy coupling between the air velocity of centrifugal dust collector, the pressure loss, power consumption and the efficiency of dust collection, though too high air velocity can improve efficiency of dust collection, but certainly will cause that the pressure loss and power consumption are too big, cause operating cost significantly to increase, thereby air velocity can only be limited in 8～18m/s in the porch, and efficient only is about 70% during the equipment operate as normal.Secondly, the ash part of unloading of centrifugal dust collector must tight zero-clearance, and having slightly leaks out will cause efficiency of dust collection to reduce significantly.Many users cause efficiency of dust collection not high because of unloading the mismanagement of ash part, and the outlet dust concentration surpasses national specified discharge standard.
In order to address the above problem, the scientific research personnel has invented a kind of atmospheric fallout particle centrifugal purifier with rotary filter net disk in recent years, this rotary filter net disk is mainly by outer rim, central axle sleeve, the radial support muscle, and one along the circumferential direction relatively rotate between outer rim and axle sleeve, twine along the two-sided winding braiding of diametric(al) is formed, its operation principle is the high speed rotating that is radially-arranged rotary filter net disk by twine, micronic dust particle in the atmosphere is collided by twine, cutting, interception is got off, and under action of centrifugal force, throwing away the filter screen dish and collect. this filter screen dish can make harmful micronic dust particle break away from by force, and is splendid to the clean-up effect of atmosphere. but still there is following weak point in it:

Its two, this filter screen dish is when knitting forming, the winding of twine is turned back a little or fixing point is positioned at the diameter two ends of outer rim, it is the multi-segment structure that twine only can be separated into the outer rim diameter length, the length of every section twine is big more, and it is just high more to knit the required coefficient of tension of silk, and the probability that twine snaps is also big more.And, when the filter screen dish rotates at a high speed, every section twine produces under the bump of windage and micronic dust particle easily and stretches, cause unbalance stress, eccentric force to increase, the balance of filter screen dish required maintenance when rotated is destroyed, cause bad phenomenon such as vibrations, noise and motor load increase, reduce service life.
They are three years old, this filter screen dish is when knitting forming, every section twine is to be close to the other end edge that central axle sleeve is wound into outer rim from an end margin of outer rim, in fact it can not pass the theoretical center of circle of outer rim, can only be the diameter shape that is similar to, and locate to exist certain juxtaposition braiding phenomenon from beginning to end at twine.Like this, when the filter screen dish rotates at a high speed, still can have off-centre and energy imbalance slightly, the micronic dust particle packing also appears in juxtaposition braiding place easily to be stopped up, and causes windage increase, the noise of filter screen dish to increase, tackle decrease in efficiency.
This shows, keep stability, balance and the interception efficient of this filter screen dish under the long-term operation state, and reach the effect of energy-saving and noise-reducing, its structure still needs further improvement and is perfect.
