Abstract
The utility model relates to an electric dust collector with a pre-collecting device which is vertically arranged between the opening of an air inlet channel and a guide plate; the pre-collecting device is composed of a suspension plate and a plurality of baffles arranged on the suspension plate. The pre-collecting device effectively makes use of the pervasion, sedimentation, collision, inertia and other aerodynamic principles to collect the powder dust in the high concentration dust-laden gas into the pre-collecting device so as to effectively reduce the dust concentration in the electric field of the dust collector and prevent corona obstruction in the electric field. The electric dust collector of the utility model has the advantages of simple structure, obvious effect, as well as low manufacturing and maintenance costs, which is applied to desulfurized electric dust collectors or bag filters.
Description
Technical field
The utility model relates to a kind of deduster, especially a kind of electric cleaner that has the device that gathers dust in advance.
Background technology
Economic society is constantly progressive, development, and more and more higher to environmental requirement, deduster is used also more and more widely in production practices, and especially electric cleaner is commonly used in industries such as chemical industry, electric power, smeltings.At present, domestic coal steam-electric plant smoke is handled a large amount of cyclic semidry process desulphurization systems that adopt, and the cleaner after the desulfurization adopts electric cleaner or sack cleaner.Because very big variation has taken place for the composition and the characteristic of dust in the flue gas after desulfurization, some variation helps the capture of deduster to dust, as the reduction of flue-gas temperature, and increase of water content or the like.It is unfavorable greatly inevitably to bring to deduster again simultaneously, as owing to adopted grey circulation desulfurization technology, has caused that the urgency of import Dust Capacity increases etc., no matter be to electric cleaner or sack cleaner all has very big influence.For electric cleaner, according to the theory of gathering dust of electric cleaner, the dust content that enters flue gas in the electric field is answered≤60g/Nm especially
3, if dust content is too high, corona blocking will appear in electric field, thereby causes equipment performance to descend.And adopt in the flue gas after the cyclic semidry process desulfurization dust content generally at 800-2000g/Nm
3, very easily produce corona blocking, so, should take measure pointedly to solve this problem to the electric cleaner after the cyclic semidry process desulfurization.
Summary of the invention
The purpose of this utility model be a kind of simple in structure, effect of design significantly, make the low electric cleaner that has the device that gathers dust in advance of maintenance cost.The technical solution of the utility model is so to realize:
A kind of electric cleaner that has the device that gathers dust in advance, comprise air intake passage (3) and deflector (6), electric cleaner electric field (8) in it, be provided with the device that gathers dust in advance (5) of vertical layout between air intake passage mouth (9) in the described air intake passage (3) and the deflector (6), the device (5) that gathers dust in advance is to be made up of suspension plate (2) and some deflection plates (1) provided thereon, described deflection plate (1) both sides are vertical mutually, and be in tilted layout, each deflection plate (1) vertical direction is successively arranged.
As preferably, described deflection plate (1) angle of inclination is for being rotated counterclockwise the 20-35 degree.
The utility model utilize dusty gas in air intake passage (3) air intake passage mouth (9) and deflector (6) between be provided with the device that gathers dust in advance (5) of vertical layout, the device (5) that gathers dust in advance is made up of suspension plate (2) and some deflection plates (1) provided thereon, deflection plate (1) both sides are vertical mutually, and be in tilted layout, each deflection plate (1) vertical direction is successively arranged.The device (5) that gathers dust in advance effectively utilizes diffusion, sedimentation, collision, aerodynamic principles such as inertia, enter the device that gathers dust in advance (5) at high concentration dusty gas (4) by air intake passage mouth (9), because flow area enlarges, gas flow rate is reduced rapidly, be beneficial to the gravitational settling of dust, then gas and deflection plate (1) bump, dust is separated from the gas under action of inertia, thereby make the dust in the high concentration dusty gas (4) in the device that gathers dust in advance, obtain capturing, reduce dust content in the electric cleaner electric field effectively, prevented the generation of corona blocking phenomenon in the electric field.The utlity model has simple in structure, effect significantly, make the low characteristics of maintenance cost, be applicable to electric cleaner or sack cleaner after the desulfurization.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is the partial enlarged drawings of device (5) of gathering dust in advance.
The specific embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment: with reference to the accompanying drawings 1, accompanying drawing 2, a kind of electric cleaner that has the device that gathers dust in advance, comprise air intake passage (3) and deflector (6), electric cleaner electric field (8) in it, be provided with the device that gathers dust in advance (5) of vertical layout between air intake passage mouth (9) in the air intake passage (3) and the deflector (6), the device (5) that gathers dust in advance is made up of suspension plate (2) and some deflection plates (1) provided thereon, deflection plate (1) both sides are vertical mutually, and 25 degree that tilt arrange that each deflection plate (1) vertical direction is successively arranged.
During work, high concentration dusty gas (4) enters the device that gathers dust in advance (5) with the speed of 15m/s by air intake passage mouth (9), because actual internal area enlarges, gas flow rate is reduced rapidly, be beneficial to the gravitational settling of dust, then gas and deflection plate (1) bump, and dust is separated from the gas under action of inertia, thereby make the dust in the high concentration dusty gas (4) obtain capturing in the device that gathers dust in advance, the gas after gathering dust in advance enters in the electric cleaner electric field (8) behind deflector (6) water conservancy diversion.
Claims (2)
1, a kind of electric cleaner that has the device that gathers dust in advance, comprise air intake passage (3) and deflector (6), electric cleaner electric field (8) in it, it is characterized in that being provided with between air intake passage mouth (9) in the described air intake passage (3) and the deflector (6) device that gathers dust in advance (5) of vertical layout, the device (5) that gathers dust in advance is to be made up of suspension plate (2) and some deflection plates (1) provided thereon, described deflection plate (1) both sides are vertical mutually, and be in tilted layout, each deflection plate (1) vertical direction is successively arranged.
2, the electric cleaner that has the device that gathers dust in advance according to claim 1 is characterized in that described deflection plate (1) angle of inclination is for being rotated counterclockwise the 20-35 degree.
