Description

(54) ELECTROFILTER

one

The invention relates to the field of gas cleaning and can be used in the chemical metallurgical, cement and other industries where it is required to clean dust from gases when they are released into the atmosphere.

An electrostatic precipitator is known, which contains precipitation electrodes, placed at the upper ends in the suspension beams and equipped with shanks at the lower ends, fixed agitation beams and a shaking mechanism, made in the form of a chain transmission, on the chains of which the contact elements that engage with the tailings of the precipitation electrodes . The suspension beams are provided with grooves in which the upper ends comprise collecting electrodes, the lower ends of which rest on the agitation beams, which are provided with slots for shanks having bevels in the direction of the chain transmission. The shaking mechanism is equipped with a second chain drive, and its contact elements are made in the form of wedge-shaped rods having a bevel that coincides with the bevel direction

shanks and fixed between chains. gears 1.

This electrostatic precipitator and its shaking device are complex in design and, therefore, have low operating reliability.

The closest in technical essence to the proposed is an electrostatic precipitator, comprising a housing, collecting electrode electrodes collecting electrodes with upper and no shanks mounted in Bepxioix guides and lower beams, and shaking mechanisms of collecting electrodes connected in the form of rolls with cams connected with drive 2.

However, such an electrostatic precipitator does not provide high efficiency of gas cleaning from Sh.Sh. and is not reliable in operation, since it does not provide protection of working surfaces of the shaking mechanisms from dust deposition, as well as from smothering as a result of repeated collisions. All this reduces the ischevvnost blows prn shaking and entails increased wear of these surfaces with the deterioration of the shaking of the electrodes, then, in turn, reduces the reliability of the electrostatic precipitator.

The purpose of the invention is to increase the efficiency of dust removal from dust by reducing the reverse dust removal and increasing the reliability of the electrostatic filter.

This is achieved by the fact that the proposed electrostatic precipitator is provided with shock-resistant overlays located on the lower shanks and lower beams, cut-off peaks installed above the plates, and side guides mounted on the precipitation electrodes; The shafts of the shaking mechanisms are mounted on the upper beams, with openings for the shaft shafts in the upper shanks, and the lower beams mounted perpendicular to the collecting electrodes.

FIG. 1 schematically shows an electrostatic precipitator, vertical section; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 - installation of one precipitation electrode; in fig. 4 shows a section BB in FIG. 3; in fig. 5 shows a section B-B in FIG. 3

The electrostatic precipitator includes a housing 1, corona electrodes 2, collecting electrodes 3 with upper and lower shanks 4 and 5, respectively. The upper shanks 4 are installed in the direction of the upper elements of the upper beams 6, and the lower shanks 5 are installed between the guide elements 7 fixed on the lower beams 8. On the upper beams 6 there are shafts 9 with cams 10, entering into the holes 11, full 1e in the upper shanks 4. The cams 10 are placed on the shafts 9 connected to the drive at an angle of O-360 ° C. On the lower shanks 5 and on the lower beams 8 there are shock-resistant lining 12 and 13, dust-removing visors 14 are installed above the lining 12. 1 5. The lower beams 8 are installed perpendicularly. collecting electrodes 3.

The electrostatic precipitator works as follows.

The dust contained in the gas to be cleaned is deposited on the collecting electrodes 3. As the shafts 9 rotate, the cams 10 enter alternately into the openings 11 of the upper shanks 4, raise the collecting electrodes 3 to a predetermined height and drop them onto the lower beam 8, resulting in the dust deposited on the collecting electrodes 3 is streamed into the hopper.
