Abstract
The utility model provides a gas homogenizing structure of an inlet of a static dust collector. A flow splitting separation plate is vertically mounted at the lower middle part of the inlet of an electric dust collector, which is vertical to the top of a circular inlet pipe, along a bending direction of the inlet of the circular inlet pipe; a baffling plate is mounted at one side which is close to a front end gas distribution plate; two groups of angular baffling plates are mounted at a round-heaven and square-earth section; two rows of arc-shaped steel pipes which are uniformly distributed are arranged below the angular baffling plates according to upper and lower layers; the two rows of the steel pipes are crossly staggered; three flow guide plates are mounted below the arc-shaped steel pipes; and two groups of wave-proof plate type flow guide plates are mounted on the side wall of the shell in front of the front end gas distribution plate. The horizontal static dust collector for an upper part air inlet manner is mainly used for homogenizing and distributing a dust-containing air flow entering the front end gas distribution plate; and particularly, the horizontal static dust collector for the upper part air inlet manner can be effectively adjusted aiming at the condition that the inlet is provided with a sharp-bend pipeline and the front space of the front end gas distribution plate is narrower, so as to meet the requirements of a dust-collecting electric field; and the dust-collecting efficiency of the horizontal static dust collector can be effectively improved.
Description
Technical field
The utility model relates to a kind of electrostatic precipitator import arrangement; Be mainly used in the horizontal electrostatic precipitator homogenizing of top intake method and distribute and get into the dust-contained airflow before the front end gas distribution grid, especially can effectively adjust to the horizontal electrostatic precipitator of top intake method that defective such as sharp turn pipeline is arranged before the import.
Background technology
The most horizontal electrostatic precipitators that adopt the top intake method of alumina producing equipment---hydroted alumina gas suspending roasting furnace, the horizontal electrostatic precipitator of this top intake method only carries out gas homogenization through laying one or two layer of distribution of gas orifice plate before the dust collection electric field after import.But owing to roaster structure reason; The pipeline that gets into horizontal electrostatic precipitator turns for the sharp turn mostly and inserts electrostatic precipitator backward; And electrostatic precipitator import termination is narrow to the space between the front end distribution of gas orifice plate, and the dust-contained airflow that gets into electrostatic precipitator causes whole gas field distribution of gas inhomogeneous because the bending break-in of connecting line and confined space influence become disorderly; Can't the air-flow of disorder be alleviated, and slow down gradually.Dusty gas is clamp-oned the dust collection electric field part through front end distribution of gas orifice plate at a high speed; Cause front end distribution of gas orifice plate not reach the homogenizing purpose; The dust collection electric field excessive inequality of passage air communication of respectively gathering dust; The electrostatic precipitator dust-collecting efficiency is low, and aluminum oxide dust directly enters atmosphere, and environment is caused severe contamination.
The utility model content
The confined space influence of import termination becomes disorderly because the bending break-in of connecting line and electricity gather dust to the dust-contained airflow that gets into electrostatic precipitator; The whole electricity that the causes gas field distribution of gas of gathering dust is inhomogeneous; The utility model provides a kind of distribution of gas arrangement, can make dust-contained airflow before arrival front end distribution of gas orifice plate, obtain inducing the homogenizing distribution and slow down flow velocity.
The technical scheme that the utility model adopted is:
Electrostatic precipitator inlet gas equalizing structure; Gather dust import and the top inlet pipe that comprise the electrostatic precipitator electricity; It is characterized in that: gather dust the import circular inlet tube middle and lower part vertical with the top along split-flow baffles 1 of the vertical installation of circular inlet tube import wrap direction at electricity, wherein forward end gas distribution grid one side is installed a deflection plate 2, in the hemispherical dome section two groups of dihedral deflection plates 3 is installed; The steel pipe 4 that below dihedral deflection plate 3, is uniformly distributed with by up and down two-layer laying two row's arcs; It is staggered that two row's steel pipes are cross, and three deflectors 5 are installed below curved steel tube 4, in the housing sidewall in front end gas distribution grid the place ahead two groups of board-like deflectors 6 of wave resistance is installed.
The beneficial effect of the utility model is; Before dust-contained airflow gets into the electrostatic precipitator dust collection electric field, induce effectively to be uniformly distributed with and to slow down gas flow rate, thereby make dust-contained airflow evenly get into dust collection electric field through the air-flow distribution orifice dispersedly, reach suitable electrostatic dust collection treatment requirement; Effectively improve the dust-collecting efficiency of electrostatic precipitator; Reduce dust-exhausting quantity, reduce economic loss, satisfy the needs of environmental protection, cleaner production.

In the drawings, the 1st, split-flow baffles, the 2nd, deflection plate, the 3rd, dihedral deflection plate, the 4th, steel pipe, the 5th, deflector, the 6th, deflector.
The specific embodiment
Gather dust the import circular inlet tube middle and lower part vertical along split-flow baffles 1 of the vertical installation of circular inlet tube import wrap direction at electricity with the top; Air-flow is divided into two; Wherein forward end gas distribution grid one side is installed a fritter deflection plate 2 local air flow is altered course; Deflection plate needs identical with the hemispherical dome barrel angle of subtend, and need guarantee that flow area is not less than circular inlet tube flow area.
In the hemispherical dome section two groups of dihedral deflection plates 3 are installed, air-flow is concentrated to the middle part.
It is staggered that steel pipe 4, the two row's steel pipes that below dihedral deflection plate 3, are uniformly distributed with by up and down two-layer laying two row's arcs are cross, preliminary homogenizing air-flow.
Three deflectors 5 are installed below curved steel tube 4, turbulence is become laminar flow.
In the housing sidewall in front end gas distribution grid the place ahead two groups of board-like deflectors 6 of wave resistance are installed, the flow direction of adjustment local gas, further homogenizing gets into the preceding air-flow of airflow-distribution board.
