Description
Technical field
A kind of distribution device in gas-fluid of electrostatic precipitator relates to the improvement of the distribution device of electrostatic precipitator in a kind of sulfuric acid industry production.
Background technology
In gas washing in SA production, the gas distribution of traditional electrical mist eliminator is for being provided with distribution device in gas-fluid in the bottom of electrostatic precipitator, the structure of this distribution apparatus is the whole horizontal panel that adopts, even air hole distribution and size are consistent, though the grid distributor of this kind structure can improve the air-flow distribution situation in the equipment to a great extent, can only be at the less electrostatic precipitator of separate unit area (general 26m
2About/platform).(separate unit reaches 39m to the big area electrostatic precipitator novel to present sulfate system
2/ platform), adopt traditional gas distribution grid, through actual measurement, gas speed can reach more than the 2m/s in the local anode tube, cause the fracture of part polar curve, and some gas speed can only reach 0.2-0.3m/s, makes demist efficient totally descend.
Summary of the invention
The utility model purpose is at traditional inhomogeneity deficiency of gas distribution grid gas distribution, and a kind of simple in structure, distribution device in gas-fluid of being convenient to install, can further improve the inhomogeneity electrostatic precipitator of gas distribution is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of distribution device in gas-fluid of electrostatic precipitator is characterized in that this distribution device in gas-fluid structure is the grid distributor of four shuttles " umbrella " shape of being made up of four inclined-planes.
The distribution device in gas-fluid of a kind of electrostatic precipitator of the present utility model is characterized in that the qi-emitting hole of its grid distributor is increased from inside to outside successively by outside aperture, " umbrella " face center.
The distribution device in gas-fluid of a kind of electrostatic precipitator of the present utility model is characterized in that being provided with stiffening web between the seamed edge of four inclined-planes of its grid distributor handing-over.
The distribution device in gas-fluid of a kind of electrostatic precipitator of the present utility model, device is at electrostatic precipitator gas import and export place, on four inclined-planes of distribution apparatus, open some apertures, total circulation area of aperture is close with the sectional area of importing and exporting pipe, according to the fluid characteristics of air-flow in pipe, gas speed around the airflow velocity ratio of air-flow central position wants high relatively, therefore has only reduced bore gas speed gently, so the aperture of gas distribution grid increases from inside to outside successively, thereby the equipment of assurance each point gas speed is roughly the same.
Gas distribution grid of the present utility model is installed on the electrostatic precipitator import and export position, and pore size therefrom becomes big around the mind-set successively on the inclined-plane, thereby makes gas distribution more even, avoids the gas bias current, has guaranteed the equilibrium of single tube electricity demist efficient; On four inclined-planes of gas distribution grid, stiffening web is arranged respectively, to guarantee the intensity of plate; Be fixed in electrostatic precipitator inside with bracing frame.This mist eliminator has not only improved detersive efficiency greatly, has prolonged the operation and maintenance life-span of follow-up equipment.This novel electrostatic precipitator puts into operation and shows that according to present test result two sections electrostatic precipitators outlet acid mist content are well below national standard 0.005g/Nm
3Gas flow rate is evenly distributed in the pipe, and the average gas flow velocity is at 1.2m/s in equipment, and electrostatic precipitator flow velocity everywhere is no more than 1.187～1.216m/s, makes the processing tolerance of single device improve more than 40%, for large-scale electrostatic precipitator suitability for industrialized production provides foundation.
The distribution device in gas-fluid of a kind of electrostatic precipitator of the present utility model, can guarantee gas uniform distribution on the electrostatic precipitator cross-sectional area, thereby improved the fog effect that removes of electric mist, also reduced to have prolonged the work-ing life of electric mist polar curve simultaneously because of of the damage of gas concentration of local to electric mist polar curve.

Embodiment
A kind of distribution device in gas-fluid of electrostatic precipitator, its distribution device in gas-fluid structure are the grid distributor 1 of four shuttles " umbrella " shape of being made up of four inclined-planes; The qi-emitting hole 2 of grid distributor is increased from inside to outside successively by outside aperture, " umbrella " face center; Between the seamed edge of four inclined-plane handing-over of grid distributor, be provided with stiffening web 3.
The distribution device in gas-fluid of a kind of electrostatic precipitator of the present utility model, device is at electrostatic precipitator gas import and export place, on four inclined-planes of distribution apparatus, open some apertures, total circulation area of aperture is close with the sectional area of importing and exporting pipe, according to the fluid characteristics of air-flow in pipe, gas speed around the airflow velocity ratio of air-flow central position wants high relatively, therefore has only reduced bore gas speed gently, so the aperture of gas distribution grid increases from inside to outside successively, thereby the equipment of assurance each point gas speed is roughly the same.
The gas distribution grid material is CFRP, flat design with traditional air distribution plate, change the grid distributor that adopts four shuttle " umbrella " shapes close with tower structure, determine the position of opening of grid distributor according to the distribution situation of anode tube, the gas passage of each perforate distribution root anode tube, dividing six layers arranges, the propulsion source of air-flow comes from the blower fan (perforate at the equipment top, middle perforate) of electrostatic precipitator, keep the even of each anode tube internal pressure, flow velocity, key is to be uniform space of pressure distribution of manufacturing, exit.
Consider that from the aerodynamics angle gas that is in the central position should be subjected to bigger blower fan tractive force, gas all around is then corresponding to be subjected to less tractive force.If median pore radius is excessive, a large amount of gases are concentrated by the intermediary anode tube, cause the skewness of tolerance, gas speed, therefore, have only that an inclined-plane amplifies successively from center to four with the aperture, gas speed makes all the other air-flows enter in the bigger pore in aperture along four inclined-planes of gas distribution grid so gently, thereby the gas speed that guarantees single tube is unanimous on the whole.According to simulation test and industrialization on-the-spot test, each layer perforate enlarges from the inside to surface gradually, and establishing center one deck opening diameter is ￠, and outside opening diameter is respectively 1.002 ￠ from the lining, 1.005 ￠, 1.010 ￠, 1.017 ￠, 1.028 ￠.On four inclined-planes of gas distribution grid, add stiffening web respectively one, increase its intensity.To up and down with bracing frame 4, gas distribution grid is fixed on electrostatic precipitator 5 inside.
