Abstract

The utility model belongs to an electrostatic vortex dust remover. The inner part of an expanding-type vortex separator is provided with a high-voltage multilayer electrostatic field, and stainless steel burr coronal wires are arranged in a cylinder and an expanded cone area; thus, a closed loop negative network is formed. The expanding-type vortex separator is designed according to the calculation formula of rotation fluid mechanics, and the sectional dimension of an air inlet, the diameter of the cylinder, an expanded angle and a convergence angle are all strictly calculated according to the flowrate of dust. A strong rotational flow field is formed after dust airflow enters; thereby, the dust can be removed and subsided by inertial centrifugal force and gravity, and dust can be also collected in the high-voltage electrostatic field for removal. The electrostatic vortex dust remover which adopts two sets of asynchronous vibrating mechanisms, a dust hopper and a dust unloading system has the advantages of convenient operation, compact structure and good dust removing effect.

Description

Expanded type whirlwind multilayer electric field dust arrester
The utility model belongs to the cyclone electrostatic dust arrester.
The combining structure that pipeline and chimney dust static retracting device multiple-effect adopt cyclone separator to connect with the electrostatic dust collection chamber is promptly once gathered dust with cyclone separator earlier, utilizes electrostatic dust collector to carry out secondary again and gathers dust.This device volume is big, and materials are many.The patent No. is that the single string multi electric field dust arrester of ZL93235115.8 places Whirlwind barrel inside to the high-voltage electrostatic field, makes compact conformation, accounts for to occupy a narrow space.This device adopts Whirlwind barrel in the outward turning air duct body suit, inside and outside Whirlwind barrel upper end is not communicated with, the lower end is communicated with, the high-pressure dust-cleaning corona wire all is housed in inside and outside Whirlwind barrel carries out electrostatic precipitation, inlet and outlet all is arranged at the cylindrical shell end side surface, in injecting dust-contained airflow with line cutting structure, air inlet in the Whirlwind barrel, realizes the high-voltage electrostatic field dedusting of machinery inertial power dedusting and inside and outside cylindrical shell.But because the relative air inlet sectional dimension of this design inner barrel diameter is less than normal, inward turning is flowed through and is limit the outlet of wind cone to reflect by revolving on the lateral again, and outer eddy flow field is damaged; Pressure and VELOCITY DISTRIBUTION are inhomogeneous and make the part blind area, flow field occur, influence the effect of dedusting.
The purpose of this utility model is a kind of dust arrester of development, can remove airborne dust, good dedusting effect effectively.
To achieve these goals, this dust arrester adopts expanded type whirlwind multilayer electric field structure, and high pressure multilayer electrostatic field promptly is set in the expanded type cyclone separator, realizes turn fluid dust particle centrifugal inertial force and gravitational settling dedusting and high-pressure electrostatic precipitation.The concrete structure of this dust arrester is: the outer cylinder body of separator is divided into three sections, and epimere is a cylinder, and the stage casing is an extended cone, and hypomere is the inverted cone dust hopper.Air inlet is horn-like at outer cylinder body upper side incision volute casing, and cross section is a rectangle.Stainless steel fish tail barbed nail corona electrode spreads all over the outer cylinder body periphery of inner wall, and parallel with wall, with the outer wall cross section be that concentric circles equidistantly distributes.Be equipped with radiation shield, dust hopper and ash discharging system in the lower end of stage casing extended cone.Discharge pipe is a cylinder, is positioned on outer cylinder body top.The outer cylinder body outside is equipped with vibration body.During work, the cyclone separator outer cylinder body is anodal, and stainless steel fish tail barbed nail corona electrode is a negative pole, forms closed loop negative pole network structure, forms the high-voltage electrostatic field.
After the dust air-flow enters separator from the cyclone separator air inlet, form strong cyclone field with 180 ° of involutes near the outer wall area backspin, the turn radius enlarges gradually along with cone, behind radiation shield, most of air-flow is reflected and does motion in the other direction, the fraction air-flow enters dust hopper and remakes ascending motion through the air-vent of radiation shield, gathers after the exhaust outlet of top is discharged.According to the inhomogeneities of the distribution of the speed of cyclone separator and pressure, corona wire is arranged on eddy flow field one side under the cyclone separator expansion involute, overcomes the blind area, flow field.In the turn fluid process for the helical movement, under action of centrifugal force, constantly dust particle is thrown to, lost the ability of advancing through the high-voltage electrostatic field capture with the wall bump near outer wall area and wall; Gravitate falls when rapping, falls dust hopper through the annular space of radiation shield periphery, realizes the effect that whirlwind and static double action are gathered dust.
Below in conjunction with drawings and Examples the utility model dust-precipitator is described further.
Fig. 1 is the profile of expanded type whirlwind multilayer electric field dust arrester installation.
Fig. 2 is a radiation shield front sketch.
Among Fig. 1, air inlet 1 is in the upper end of the first half cylinder 7 of outer cylinder body, and the air inlet cross section is rectangle, and inner barrel 9 is a cylinder, and with cylinder 7 coaxial lines, at the outstanding certain-length in the top of cylinder 7, air outlet 2 is in the inner barrel upper end, and 5 is the air inlet volute casing; 3 is insulated terminal, connects stainless steel fish tail barbed nail corona electrode 4; Corona wire 4 is parallel with wall in the inboard of whole device, and is concentric circles and equidistantly distributes with wall; The following of cylinder 7 is downward extended cone 8, and extended corner is α 1The lower end of device is to shrink cone downwards, and as flue-dust retainer 11, angle of throat is α 2Be connected with downward extended cone cylinder.Radiation shield 10 is equipped with in flue-dust retainer 11 upper ends; 6 is that two covers are asynchronous for vibration body, is contained in the device outside, circuit control when adopting 555 bases.The skin of device is a heat-insulation layer; 12 is detecting gate, and 13 is cinder-discharging port.
Among Fig. 2,15 is the annular space of radiation shield.
During concrete enforcement, the expansion cone angle 1Choose 5 ° 30 ' to 6 ° 45 ', angle of throat α 2Choose 17 ° 15 ' to 19 ° 30 '.
