しなければならない程の塵が溜まる。A tubular electrical filter is known from DE 2919989 A1. In this filter, tubular dust collecting electrodes are assembled into a plurality of set-like units that rest on a cushion. The unitized tubular dust collection electrodes are connected to an impact-type shake-off device. This shake-off device causes the dust collection electrode to periodically vibrate in the vertical direction during operation of the electric filter. The dust thus shaken off from the collecting electrode falls against the gas flow onto the saddle bottom of the electric filter and is discharged by a screw conveyor into a central hopper. Between the lower end of the tubular dust-collecting electrode and the raw gas supply, a separating grid with helical inserts is provided, which serves as gas damming and gas distribution medium. In this case, the dust shaken off from the dust collecting electrode must fall against the gas flow through the openings of the separation grid to the bottom of the filter. Therefore,
A portion of the dust shaken off from the dust collection electrode is carried upward again by the gas flow, and the electric field of the dust collector adversely affects the dust collection efficiency. Furthermore, a gas vortex is formed on the separation grid, and this vortex collects enough dust between the separation grid and the dust collecting electrode that the electric filter has to be shut down.

積や循環を確実に防ぐことができる。This problem is solved by the fact that the dust evacuation gutter is provided at a distance below the dust collection electrode connected to the dust removal device, and spreads out in a fan shape from the center of the inside of the casing and radially outwards toward the bottom wall of the casing in a conical shape. This problem is solved by the fact that it is provided so as to extend to. By arranging the dust evacuation trough below the dust collecting electrode according to the invention, it is possible, on the one hand, to distribute the untreated gas flow uniformly over the entire cross section of the electric filter, without the formation of undesirable vortices. On the other hand, the dust that is shaken off from the collection and discharge electrodes and falls into the dust discharge trough does not come into contact with the gas stream again. Therefore, accumulation and circulation of dust within the separation chamber can be reliably prevented.

出される。The electrostatic precipitator shown in FIG. 1 consists of a cylindrical upper part 1 of the casing and a funnel-shaped bottom part 2. In the upper region of the two-sided part 1 of the casing, a tubular dust collecting electrode 4
is loosely suspended from the support structure 3. In the lower region of the upper part 1 of the housing, the tubular dust-collecting electrode 4 is guided in a guide plate 5 with a small play. On this information board 5,
A dust collection electrode 4 provided on the outside of the filter casing
A mechanical dust removal device, that is, a cleaning device 6, which vibrates periodically in the horizontal direction operates. By applying periodic shocks from this mechanical dedusting device 6 via the guide plate 5 to the dust collecting electrode 4, the tubular dust collecting electrode 4 is extremely advantageous since its play within the guide plate 5 is small. vibrates horizontally. The dust separated by the dust collection electrode is reliably released from the dust collection electrode by this vibration, and is discharged downward from the dust collection electrode.

られる。Below the dust collection electrode 4 and discharge electrode 7 (・dust discharge gutter 9,
10 are provided one above the other at intervals in the funnel-shaped bottom portion 2. The dust evacuation trough is provided so as to fan out from the center of the interior of the cage 5-ring and extend conically outward in the radial direction towards the bottom wall 2 of the casing. In this case, the dust discharge troughs 9, 10 are arranged such that the upper dust discharge trough 10 covers the gap between the lower dust discharge troughs 9. Therefore, the dust does not pass between the dust discharge troughs 9 and 10 and fall downward. Dust collection electrode 4 and discharge electrode 7
Dust that falls into the gutters 9, 10 during periodic dedusting is guided towards the funnel-shaped bottom wall 2. At that time, dust is in this area,
This is very advantageous since it does not come into contact with the dust-containing gas which is introduced from below the dust discharge troughs 9, 10 through the pipes 12. The separation area with the dust collection electrode 4 and the discharge electrode 7 is thus protected from undesirable dust loads, resulting in a very high dust collection efficiency.

ガスは集塵機から矢印14に沿って上方へ排出される。Furthermore, by arranging the dust evacuation trough 9.10 according to the invention below the dust collection electrode 4 and the discharge electrode 7, it is very advantageous that the dust-laden gas is evenly distributed over the entire cross section of the dust collector. . This uniform distribution of gas makes it possible to load the collecting electrode 4 and the discharge electrode 7 provided in the electrostatic precipitator uniformly in all directions. The dust separated from the gas in the dust collector is continuously or periodically discharged downwards from the bottom part 2 along the arrow 13, and the gas from which the dust is liberated is discharged upwards from the dust collector along the arrow 14. .

着している塵が遊離する。As shown in FIG. 2, it is advantageous if the tubular dust collecting electrode 15 of the electrostatic dust collector according to the invention is equipped with a pneumatically operated dust removal device. For this purpose, the upper region of the tubular dust collection electrode 15 is covered with two covering plates 16.
17 and is airtightly connected. The tube 15 is provided with a number of ring-shaped slits 18 in the tube wall in the region between the plates 16 and 17. This slit extends diagonally downward toward the center of the tube. Air, steam or other inert gas at a projecting pressure, for example 10 atmospheres, passes from the outside through the chamber 19 between the cover plates 16 and 17 into the slit 18.
The dust adhering to the inner wall of the tubular dust collecting electrode 15 is thereby liberated.
