Dry-wet-combining multi-stage dust removing device for mine

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...

Problems solved by technology

[0005] In order to solve the problems that mine dust endangers the health of miners in mine production, the existing dust removal device has high energy consumption, poor adaptability to the underground environment, while simplifying the complexity of the device structure, it cannot effectively improve the dust removal efficiency and cause secondary pollution. Further provide a mine wet and dry combined multi-stage dedusting device
