Embodiment Construction

[0026] The dry-wet combined multi-stage dust removal device for mine includes a Venturi tube dust collection mechanism placed outside the dust removal box, a first-stage dry dust removal mechanism, and a second-stage wet dust removal mechanism placed inside the box. When the high-speed air flow is passed through the inlet of the Venturi tube, its speed will be accelerated to the maximum at the throat, and a huge pressure drop will be formed here. Using this pressure drop and cooperating with the dust collection hood, the external mineral dust can be sucked in into the dust collector. After the mine dust enters the interior of the device, it first enters the optimized cyclone dust collector for primary treatment. The optimized cyclone dust collector uses centrifugal force to separate the larger-sized ore dust, and the separated ore dust particles fall from the lower ash-falling circular straight pipe. Using centrifugal force to separate mineral dust can reduce the workload of ...

Abstract

The invention relates to a dry-wet-combining multi-stage dust removing device for a mine. The dry-wet-combining multi-stage dust removing device comprises a Venturi-tube dust capturing mechanism arranged on the outer side of a dust removing device box, a cyclone-dust-remover first-stage dry dust removing mechanism arranged in the dust removing device box and a water-spray-dust-removing second-stage wet dust removing mechanism arranged in the dust removing device box. As traditional draught fan dust sucking is replaced with Venturi tube dust sucking, a better safety effect and a better energy saving effect are achieved, and the dry-wet-combining multi-stage dust removing device can adapt to more working environments; as a cyclone dust remover serves as a mine-dust first-stage processing module, most of respirable dust can be removed, workloads of spray dust removing are reduced, and a large number of water resources are saved; as spray dust removing is used as second-stage dust removing, the dust removing effect is improved, and meanwhile the cooling effect is achieved. The dry-wet-combining multi-stage dust removing device is simple in structure, convenient to use, low in production cost, good in dust removing effect and good in large-scale popularization performance accordingly.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dry-wet combined multi-stage dust removal device for mines. Background technique [0002] There are various forms of dust removal devices, but usually it has two parts: the first part is the dust collection system, which is used to capture the dust floating in the outside air; the second part is the dust suppression system, which collects the captured dust to prevent it from escaping. At present, the more successful dust removal methods include: inertial dust removal, gravity dust removal, electrostatic dust removal, etc. [0003] Several existing dust removal methods have their own advantages and disadvantages, and the dust removal efficiency is also uneven. The inertial dust collector mainly uses the principle of different specific gravity between dust and air to make the mine dust settle down from the air by its own gravity. Although this dust removal method is simple in structure a...
