Description

Cyclone-type high-voltage electrostatic combined precipitator

Cyclone type high-pressure electrostatic combination dust-precipitator is a kind of deduster.

Existing common vertical electrostatic precipitator is in a cylinder corona wire to be set, cylinder is made dust collector pole, apply high voltage direct current, dust-contained airflow enters electric field from dust-precipitator bottom air inlet, and dust is charged, is attracted on the cylinder dust collector pole, this single cottrell has the shortcoming of reentrainment of dust when dust settling, be unfavorable for improving dust collection rate, the dust that particle diameter is little is difficult for being captured, the cooperation of generally need once gathering dust.

The purpose of this utility model is: a kind of improved cottrell design is provided, and firsts and seconds is gathered dust to be integrated in one, and does not have reentrainment of dust in the dust settling process, so that improve dust collection rate.

Specific embodiments of the present utility model is: the flue-dust retainer upper end of cyclone type high-pressure electrostatic combination dust-precipitator is connected with the lower end of metallic cylinder, the metallic cylinder upper end is connected with the exhaust chamber lower end of taking gas port out of, on the metallic cylinder outer wall earth connection is housed, vibrator, supporting base is housed on the flue-dust retainer, exhaust chamber top center dress porcelain insulator, high-voltage power-line is connected with the barbed nail corona electrode upper end through the insulation porcelain vase, be fixed with support on the metallic cylinder inwall, be fixed with a plurality of dust collector pole tubes on the support, during installation, the lower end of a last dust collector pole tube is lower than the upper end of next dust collector pole tube, dust collector pole tube top is conical, there is dust fall to use the gap between dust collector pole drum outer wall and the metallic cylinder inwall, the whirlwind tube of bringing gas port into places on the interior whirlwind tube bearing of flue-dust retainer, the gap that has dust fall to use between the outer wall of whirlwind tube and the inwall of flue-dust retainer, the upper end of whirlwind tube and isolating cylinder lower end connect as one, the top of isolating cylinder is conical, there is a cylinder at whirlwind tube center, above the whirlwind tube elastic leaf springs is housed, the porcelain insulator that is connected with the corona wire lower end is housed on the leaf spring.Support on the metallic cylinder inwall is a metallic support, has 3～4.

The advantage of this dust-precipitator is: firsts and seconds gathers dust and combines together, do not produce reentrainment of dust in the dust landing process on the dust collector pole tube, help improving dust collection rate, dust collection rate reaches 99.9%, the barbed nail corona electrode lower end is by the leaf spring tensioning, because leaf spring is flexible, corona wire extends still securablely under temperature effect, can not break during contraction, prolonged service life, reduced maintenance load, technology arrangement is simple, and civil engineering costs is economized, apply to the dryer in the cement industry, disintegrating machine, ball mill, gathering dust of equipment such as packing machine also can be used for building materials, chemical industry, metallurgical, gathering dust of industrial departments such as electric power.

Below in conjunction with drawings and Examples the utility model is further specified:

Embodiment:

Cyclone type high-pressure electrostatic combination dust-precipitator (see figure 1), by flue-dust retainer 1, whirlwind tube 2, metallic cylinder 5, support 6, dust collector pole tube 7, barbed nail corona electrode 8, exhaust chamber 9, vibrator 12, supporting base 13 and isolating cylinder 14 constitute, flue-dust retainer 1 upper end is connected with metallic cylinder 5 lower ends, the lower end of taking the exhaust chamber 9 of gas port 9a out of is connected with the upper end of metallic cylinder 5, the upper end of whirlwind tube 2 and isolating cylinder 14 lower ends are connected as a single entity, it is conical that isolating cylinder 14 upper ends are, because of fixing on the support 6, the whirlwind tube 2 of bringing gas port 2a into places on the whirlwind tube bearing 17 in the flue-dust retainer 1, gap for blanking is arranged between the inwall of the outer wall of whirlwind tube 2 and flue-dust retainer 1, be equipped with above the whirlwind tube 2 and be with flexible leaf spring 3, porcelain insulator 4 is housed on the leaf spring 3, support 6 usefulness angle bar are manufactured, fixedly connected with metallic cylinder 5 inwalls, have 3～4, dust collector pole tube 7(sees Fig. 3) upper end is for conical, be screwed on support 6, in the time of fixedly, the lower end of a last dust collector pole tube is a little less than Next upper end, fall into when making the dust landing of adsorbing on the dust collector pole tube inwall outside the conical tube body wall of next dust suction utmost point tube upper end, be not subjected to airflow influence generation reentrainment of dust in the dust collector pole tube, the external diameter of dust collector pole tube is less than the internal diameter of metallic cylinder, between guaranteeing two certain interval is arranged, earth connection 15 is housed on the outer wall of metallic cylinder 5, vibrator 12, exhaust chamber 9 top center are equipped with porcelain insulator 10, be connected to barbed nail corona electrode 8 between porcelain insulator 10 and the porcelain insulator 4,120KV high-voltage power-line 11 is connected with barbed nail corona electrode 8 through insulation porcelain vase 10.Because porcelain insulator 4 is contained in and is with on the flexible leaf spring 3, therefore, corona wire is because of cold and hot when shrinking or extend, can not break or relaxes, and helps increasing the service life, and the dust in the flue-dust retainer is by powder outlet 16 discharges.

After dusty gas enters whirlwind tube 2, rotate along barrel, the greater particle size dust is owing to enter than large space, be subjected to whirlwind tube inwall bump, speed reduces, along the sedimentation of tube inwall, fall into flue-dust retainer, obtain first gas separated after rotation in the cylinder 2b at whirlwind tube center enters dust collector pole tube 7 metallic cylinder 5, dust granules is charged, under electric field action between barbed nail corona electrode and the dust collector pole tube, charged dust is attracted on the dust collector pole tube inwall, purified gas is discharged through exhaust chamber 9 and gas outlet 9a, simultaneously, is adsorbed on dust on the dust collector pole tube inwall in the gap that enters under the rapping of electromagnetic vibrator 12 between dust collector pole tube and the metallic cylinder, fall to flue-dust retainer, because the outer sedimentation dust of dust collector pole tube separates with an interior air-flow, therefore, does not have reentrainment of dust.
