Description
Technical field
The utility model relates to deduster technology, particularly relates to a kind of filter drum type precipitator.
Background technology
In recent years, along with new technology, the development of new material, with Japan, the company of the U.S. is representative, the structure of deduster and filtrate are improved, filter cartridge dust remover is made to be widely used in cement, iron and steel, electric power, food, metallurgical, the industrial circles such as chemical industry, solve traditional deduster to collect difficulty to ultrafine dust, filtration velocity is high, ash-removal effect is poor, filter bag is easy to wear run-down, the preferred plan of the problems such as operating cost is high, with various pocket type existing on market, electrostatic precipitator compares that to have effective filtration area large, pressure reduction is low, low emission, volume is little, the features such as long service life, become the new direction of industrial dust collector development.
The basic structure of filter drum type precipitator comprises dust collector box body, filter cylinder, air-introduced machine, automatically controlled compressed air deashing device, and filter cylinder can be arranged vertically in casing, also can be in tilted layout in casing, can also be horizontally disposed in casing.As shown in Figure 1, Figure 2, Figure 3 shows, be a kind of filter drum type precipitator horizontally disposed in dust collector box body of filter cylinder; Dust collector box body is rectangle, and an inverted bucket shape dust wind inlet is arranged at top, the bucket shape dust ash bucket that bottom has just putting; Dust discharging machine and dust transfer tank is connected with below dust ash bucket; A sidewall of casing there are eight dustless wind outlets, another sidewall relative with this sidewall is provided with the filter cylinder installing hole exporting equal number with dustless wind, each dustless wind outlet is coaxial with corresponding filter cylinder installing hole, and each filter cylinder installing hole is furnished with a box sealing lid; The adjacent wall box of the sidewall exported with wind dustless described in this is provided with venting; The electromagnetic impulse valve that automatically controlled compressed air deashing device controls; Each electromagnetic impulse valve controls a compressed-air atomizer; The compressed-air atomizer that the equipped electromagnetic impulse valve of each dustless wind outlet controls; Each dustless wind outlet is installed with a frame filter cylinder support, and the other end of frame filter cylinder support has a screw rod, for installing casing seal cover; The frame filter cylinder support of each dustless wind outlet to be connected suit two filter cylinders, the aperture of filter cylinder endoporus is equal with the aperture that dustless wind exports, a sealing ring is had between the end face of an end cap of first filter cylinder and the boxboard in dustless wind exit, a sealing ring is had between the end face of an end cap of the end face of another end cap of first filter cylinder and second filter cylinder, there is a sealing ring between the end face of another end cap of second filter cylinder and box sealing lid, between box sealing lid and the sidewall being provided with filter cylinder installing hole, have a sealing ring.Air-introduced machine has a blast pipe and an exhaust duct, and the blast pipe of air-introduced machine is communicated with eight of dust collector box body dustless wind exit seals; Filter cylinder is divided into two parts dust collector box body: a part is that the cylindrical of filter cylinder and casing form dust-laden air chamber, alphabetical A region in Fig. 1, and another part is the entering of the endoporus of filter cylinder and air-introduced machine, exhaust duct forms dustless air chamber, letter b region in Fig. 1.Its operation principle is: after air-introduced machine starts, air because of dustless air chamber is taken away by air-introduced machine and makes dustless air chamber form negative pressure, under atmospheric pressure effect, dust-contained airflow continuously enters dust collector box body dust-laden air chamber side through the dust wind inlet of deduster, due to the sudden enlargement of air-flow section, it is peripheral that dust granules in air-flow is diffused into each filter cylinder by Brownian movement, the filtrate of the air permeable filter cylinder in dust-contained airflow enters dustless air chamber and discharges through air-introduced machine, and the dust in dusty gas is then intercepted by filtrate and is deposited on filter cylinder outer round surface; When filter material surface dust layer thickness increases to certain value, PLC program in automatically controlled compressed air deashing device will start electromagnetic impulse valve, compressed air is purged with the endoporus of extremely short time to filter cylinder, the filtrate of filter cylinder produces vibration of expanding, the dust be attached on filter material surface is stripped and falls into ash bucket, the dust fallen in ash bucket is discharged by unloading valve, and filter cylinder recovers filtration condition again.
The defect that prior art exists is: one is dust collector box body is all make of the thin plate of about 4mm usually, and rigidity is poor, and flatness error is larger; Two is that the structural rigidity of filter cylinder is also very weak, and it axially and radially all can not bear larger pressure.Therefore, sealing ring between filter cylinder and dust collector box body sidewall, between filter cylinder and filter cylinder and between filter cylinder and box sealing lid is difficult to be formed effectively reliably seal, particularly box sealing covers two sealing rings of installation, simultaneously for closing two different planes, it is an obvious technical error.Steam power plant's coal handling system of inventor place group company subordinate and the feeding system in starch sugar refinery have installed three such filter drum type precipitators respectively; owing to there is above-mentioned defect; the exhaust duct of air-introduced machine often can discharge some dust; and when automatically controlled compressed air deashing device performs purging action, the exhaust duct of air-introduced machine just has a large amount of dust and discharges.
