Abstract

The utility model relates to a wet -type electrostatic precipitator's pi type distribution of air flow device, including the slat of a plurality of pi types of parallel arrangement and being with it and move about freely and quickly a crossing supporting beam, the two is connected and the bars form member of formation at each crossing position, and this bars form member is fixed at the horn mouth inboard of wet -type electrostatic precipitator flue gas inlet side wall through a supporting beam's both ends, the whole stripe shape spare that the cross -section is the pi type is constituteed by genshui flat board and two risers to pi type slat. The interior distribution of air flow of wet -type electrostatic precipitator can effectively be realized to this device, is difficult for scale deposit, deformation and jam moreover, need not to wash.

Description

The �� type airflow uniform distribution device of wet electrical dust precipitator

Technical field

The utility model relates to the �� type airflow uniform distribution device of a kind of wet electrical dust precipitator for industrial flue gas cleaning.

Background technology

In the industry such as thermoelectricity, iron and steel, wet electrical dust precipitator, as the end treating plant of flue gas purification system, carries out last degree of depth dedusting except mist process, to guarantee industrial smoke minimum discharge before fume emission. Flue gas is entered in the process of wet electrical dust precipitator by inlet flue duct, need to first pass through hydraucone, and the sectional area change of hydraucone makes flue gas different at the air flow method of different section, thus producing eddy current and strong turbulent flow phenomenon, this can reduce the electric precipitation performance of wet electrical dust precipitator and total dust-collecting efficiency.

Adopt the porous plate installing multiple different percentage of open area in electric precipitator tapered inlet to realize airflow uniform distribution at present. But owing to wet electrical dust precipitator is positioned at the downstream of wet desulphurization equipment, the flue gas entering wet electrical dust precipitator is saturated wet flue gas, carries a large amount of gypsum drops in flue gas. Through long-time running, the easy fouling and clogging of porous plate, it is necessary to configuration water rinse-system rinses scale removal, adds the consumption of equipment cost and water.

Summary of the invention

The purpose of this utility model is to provide the �� type airflow uniform distribution device of a kind of wet electrical dust precipitator, produces the eddy current of air-flow and the phenomenon of strong turbulent flow to subtract, it is to increase wet electrical dust precipitator dust-collecting efficiency, it is achieved the minimum discharge of flue gas in the few wet electrical dust precipitator hydraucone of i.

The utility model �� type airflow uniform distribution device comprises the batten of multiple �� types arranged in parallel and is with it the supporting beam intersected in length and breadth, the two palisade component connecting in each intersection area and being formed, this palisade component is fixed on by the two ends of supporting beam in the hydraucone of wet electrical dust precipitator gas approach side; Described �� type batten forms, by a leveling board and two perpendicular plates, the overall bar type part that cross section is �� type.

Described �� type batten is connected with band bundle with each intersection area of supporting beam.

This device adopts the grid members of �� template formation, the inner side that it is placed in wet electrical dust precipitator gas approach side hydraucone, can increase the resistance of flue stream when hydraucone, prevents eddy current and strong turbulent flow phenomenon, change air flow method situation, reach the object of airflow uniform distribution. In this device, �� type batten is as the main body of grid members, intensity height, and preventing deformation is less scaling, can avoid blocking, it is not necessary to rinse.

Accompanying drawing explanation

Fig. 1 represents that �� type airflow uniform distribution device installs position in wet electrical dust precipitator on the suction side hydraucone

Fig. 2 is the right view of Fig. 1.

Fig. 3 is the cross-sectional structure schematic diagram of �� type batten.

Fig. 4 is that the schematic diagram being connected pricked by �� type batten with supporting beam band.

In figure, 1 wet electrical dust precipitator, 1-1 hydraucone, 2 �� type battens, 2-1 leveling board, 2-2 erects plate, 3 supporting beams, 4 bands, 5 exhaust gases passes.

Embodiment

Such as Fig. 1, the upper end of wet electrical dust precipitator 1 forms the hydraucone 1-1 to exhaust gases passes 5 transition. �� type airflow uniform distribution device is housed in the inner side of hydraucone 1-1, and this device comprises batten 2 and the supporting beam 3 of �� type. Giving conjunction Fig. 2 visible, the body of the present embodiment wet electrical dust precipitator 1 is cuboid, and namely lateral width size (such as Fig. 2) is greater than frontal width size (such as Fig. 1), so its hydraucone 1-1 is also the rectangle upwards gradually reduced. From Fig. 1 and Fig. 2 it will be seen that be provided with it in the supporting beam 3 intersected in length and breadth on the downside of the �� type batten 2 of multiple parallel interval arrangement, the two each intersection area is interconnection fixing, forms palisade component according to this and is fixed on by supporting beam 3 on the inner side-wall of hydraucone 1-1.

Fig. 3 represents the cross-sectional configuration of �� type batten 2, and it is taking the mixture of corrosion-resistant FRPP(polypropylene and glass wool cloth) adopt polyvinyl resin to be bonded to overall �� type batten as one leveling board 2-1 and two perpendicular plate 2-2 of material.

Each �� type batten 2 and each handing-over position of supporting beam 3, all prick the two connected (such as Fig. 4) with band 4.

In palisade component, the data such as the spacing between each �� template and the leveling board 2-1 width in �� template, the height of perpendicular plate 2-2 and the spacing of two perpendicular plate 2-2 are by carrying out optimization design after flow field simulation and material structure Strength co-mputation.

The utility model �� type airflow uniform distribution device can effectively realize airflow uniform distribution in wet electrical dust precipitator, and less scaling, distortion and blocking, it is not necessary to rinse.
