Abstract
The utility model discloses a dust removal device with a rotating plate for a high-voltage electrostatic dust catcher. The device comprises the rotating plate. The rotating plate is vertically arranged, and is driven by driving chain wheels, driven chain wheels and chains. Straight steel brushes are arranged on the two sides of the lower part of the rotating plate. Bristles of the straight steel brushes contact with the rotating plate. The rotating plate can move from bottom to top relative to the straight steel brushes. The straight steel brushes can be fixed on a bracket parallel to the rotating plate. Support seats are arranged at the two ends of the bracket. Adjusting screws can be arranged on the support seats at the two ends of the bracket, and through the adjusting screws, the bracket and the rotating plate get closer or farer. Secondary raised dust during dust removal is avoided; and the device is low in manufacture cost, convenient to maintain and particularly applied to the upgrading and reconstruction of the conventional old high-voltage electrostatic dust catcher.
Description
Technical field
The utility model relates to high-voltage electrostatic dust separator, especially a kind of deashing device that has the high-voltage electrostatic dust separator of rotating polar plate.
Background technology
High-voltage electrostatic dust separator is to receive the device of catching dust in the flue gas with the electrostatic depuration method, relies on discharge electrode and these two systems of receiving electrode to accomplish.Dust moves to its opposite polarity electrode under the effect of electric field force, and is deposited on the electrode, reaches the purpose of gathering dust.Two electrode systems of traditional high-voltage electrostatic dust separator all are equipped with rapping apparatus, and when beaing two-pole device, the dust that adheres to is above that shaken off, and falls into the bottom ash bucket outside ash exhauster discharge machine.The waste gas that has been cleaned is entered in the atmosphere through chimney by outlet, accomplishes the gas cleaning process.
But the problem that the ash removal equipment for flapping of conventional high-tension electrostatic precipitator mainly exists is reentrainment of dust to occur; Some can't fall into ash bucket because of the electric field air-flow dust of being shaken off by rapping; Flow into next electric field or directly enter atmosphere with air-flow from outlet; Cause discharging to exceed standard, can't satisfy the environmental requirement of increasingly stringent.Therefore; The new-type deduster that a kind of rotating polar plate adds rotation steel brush ash-clearing structure appears in the market; As on May 20th, 2009 a disclosed patent No. be that ZL200820035864.7, name are called the utility model patent of the portable dust collecting electrode electrostatic precipitator of rotating brush " band "; It includes corona discharge electrode, portable dust collecting electrode and rotating brush deashing mechanism; Corona discharge electrode is positioned in the middle of the control of dust pole plate of portable dust collecting electrode, and the wire brush of a pair of reverse rotation in the rotating brush deashing mechanism is positioned at the below of control of dust pole plate, and the steel wire bristle of rotating brush is pressed in the side of control of dust pole plate; Though the deashing device of this electrostatic precipitator can solve reentrainment of dust and absorption high resistivity dust largely, complex structure, cost of manufacture is higher; In addition owing to need to be equipped with the transmission system of stretching out outside the electrostatic precipitator framework; It takes up room bigger, only is suitable for being installed in the new electrostatic precipitator using, and for existing old deduster; Limited because of the lower space of old deduster, the deashing device of this band rotating brush can't be installed.
The utility model content
The technical problem that the utility model will solve provides a kind of deashing device that has the high-voltage electrostatic dust separator of rotating polar plate; Reentrainment of dust appears when avoiding deashing; Cost of manufacture is low, and is easy to maintenance, and is specially adapted to the upgrading of existing old high-voltage electrostatic dust separator.
For achieving the above object; The technical scheme of the utility model is: a kind of deashing device that has the high-voltage electrostatic dust separator of rotating polar plate; The rotating polar plate that comprises the vertical setting that drives by drive sprocket, driven sprocket and chain; Be provided with straight steel brush in the both sides of rotating polar plate bottom, the bristle of straight steel brush keeps contacting with rotating polar plate, and described rotating polar plate can move with respect to straight steel brush from bottom to top.
Further improve, described straight steel brush is fixed on the support that is parallel to rotating polar plate, and the two ends of support are provided with supporting seat, the installation of convenient straight steel brush.
Further improve again, can fix a plurality of straight steel brushes on the described support, further increase straight steel brush and the contact-making surface that rotates pole plate.
Further improve again, described straight steel brush through a plurality of bolts with put up 45 ° and fix, further improve ash-removal effect, and straight steel brush can be adjusted with respect to support at vertical position and angle through a plurality of bolts.
Further improve again, the supporting seat at said support two ends be provided with make support and rotating polar plate each other near or the adjustment screw rod that draws back, make straight steel brush can adjust with respect to the distance of rotation pole plate, the bristle that guarantees straight steel brush with rotate pole plate and can reliably contact.
The utility model is because a straight steel brush is arranged on the both sides of rotating polar plate bottom; The bristle of straight steel brush keeps contacting with rotating polar plate; When rotating polar plate moved with respect to straight steel brush from bottom to top, straight steel brush just can reentrainment of dust occur in the dust brush whereabouts people's ash bucket that sticks on the rotating polar plate when avoiding with vibration cleaning; And can remove high resistivity dust, satisfy the high standard emission request to greatest extent;
On the other hand, because of adopting the fixed deashing of straight steel brush, than rotating brush rotation deashing; Save rotating mechanism, so cost of manufacture is lower, easy to maintenance; Simultaneously because of need not rotating mechanism; Institute takes up space less, also can install and use for the existing less old electrostatic precipitator of lower space, is specially adapted to the upgrading of existing old deduster.

Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the B place enlarged drawing of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further explain.
Fig. 1 is to shown in Figure 3; A kind of deashing device that has the high-voltage electrostatic dust separator of rotating polar plate; The rotating polar plate 4 that comprises the vertical setting that drives by drive sprocket 1, driven sprocket 2 and chain 3; Be provided with straight steel brush 5 in the both sides of rotating polar plate 4 bottoms, the bristle of straight steel brush 5 keeps contacting with rotating polar plate 4, and described rotating polar plate 4 can move with respect to straight steel brush 5 from bottom to top.
Described straight steel brush 5 can be fixed on the support 6 that is parallel to rotating polar plate 4, and the two ends of support 6 are provided with supporting seat 7; On a support 6, be fixed with two straight steel brushes 5.
Described straight steel brush 5 also can fix for 6 one-tenth 45 ° through a plurality of bolts 8 and support.
On the supporting seat 7 at support 6 two ends, also can be provided with make support 6 and rotating polar plate 4 each other near or the adjustment screw rod 9 that draws back.
