Problems solved by technology

Disadvantage, apart from a large number of upstream wetting nozzles or water spray nozzles, is that there is no predetermined uniform water mist for wetting the dust carried in from the raw gas
In addition, the disadvantage is that the above arrangement makes it impossible for the dust removal device to be a compact structure, but only a long structure

Embodiment Construction

[0037] FIG. 1 shows a side view of a road boring machine 2 with an integrated dust removal device 1 in side view. The boring machine 2 is arranged in the working section 3 of underground drilling, which is only shown in the figure, and has a mining arm 4 with a mining crushing drum 8 and a downstream conveyor belt 5 . The dedusting device 1 is directly assigned to the boring machine 2 and is connected to the running gear 7 via a support 6 . This means that the dust collector is supported on the chassis in such a way that the position of the extraction arm 4 and the conveyor belt 5 does not affect the fastening point of the dust collector.

[0038] It can be seen in FIG. 1 that the ventilator 11 with its drive mechanism 12 is no longer arranged between the inlet side 13 and the outlet side 14 of the housing of the dedusting device, but between the demister 15 and the droplet collector 16 One of its own ventilator housings 18 on one side. The ventilator housing 18 has a noise ...

Abstract

A dusting device 1 with a demister 15 advantageously arranged standing obliquely has a very compact construction because sufficient moistening or wetting of dust-containing crude air 24 is possible through the use of intensively acting multiple stream nozzles 33. The ventilator 11 is allocated to its own ventilator housing 18 that is connected to the dusting device housing 10 and has a muffler 20inserted downstream.

Description

technical field [0001] The invention relates to a dedusting device for installation behind or on dust-generating machines and / or installations for underground mining and tunneling, the dedusting device having a dedusting device housing as separating element with a The demister of the wetting nozzle has a droplet collector, and a ventilator with a drive mechanism arranged at the inlet / outlet side area is associated with the dust collector housing. Background technique [0002] Such a dedusting device is known from DE 198 53 190 A1. This known dedusting device has a ventilator which is arranged between the inlet side and the outlet side, ie in the raw air flow, ie upstream of the mist eliminator and the droplet collector. The wetting nozzles are not only assigned to the mist eliminator suspended approximately horizontally in the air flow, or are arranged in front of the mist eliminator, but also in front of the fan wheel, so that the fan wheel not only absorbs the dust, And...
