Description
Technical field
The invention belongs to down-hole atomizing de-dusting technical field, particularly to a kind of iron mine drop shaft smart spraying depositing dust dress
Put and control method.
Background technology
Iron mine is one of important basic industries, is engaged in workman's large contingent of iron ore exploitation.With mining rate and machine
The raising of tool level, the dust pollution in mine operation area substantially, affects the safety of downhole production, especially endangers shop floor worker
Healthy, therefore atomizing de-dusting has obvious necessity.
In traditional mine, dedusting adopts artificial control or timing, set point control watering and aerosol apparatus substantially, exists
The problems such as inefficiency, waste water resource.With the development of electronic technology, employ between frame in conjunction with practical application Some Enterprises
Auto spraying, ore drawing auto spraying, the device for reducing dust according to some intelligent such as dust concentration auto sprayings.But not yet
Appearance unloads the device for reducing dust at ore deposit for iron mine drop shaft, and due to the complexity of actual field environment, common device for reducing dust is not
Can be suitable for well.
At present relatively pervasive device for reducing dust to detect dust concentration using light scattering method sensor of dust concentration, according to setting
Fixed threshold values controls sprayer unit.But sensor of dust concentration range ability is limited, easily it is subject to dust pollution, zero migration is tight
Weight, needs often to clear up, accuracy of detection is low, and error is up to 25%.The operating current of sensor is big simultaneously, sensor and controller
Required distance comparatively short.But general wind-force is larger at drop shaft, dust recycling is fast, and sensor of dust concentration detection is delayed, needs
Depositing dust area is big it is desirable to many complete equipments carry out depositing dust, and equipment cost is high, and water utilization rate is low.
Common device for reducing dust also has the device for reducing dust such as sound control type, light-operated, touch controlled type.But all can not be suitable for well
Depositing dust at drop shaft, the source that signal can not effectively be distinguished by this kind of sensor is staff or locomotive, can not distinguish
Mine locomotive type (locomotive divides loaded vehicle and empty wagons, and loaded vehicle divides the loaded vehicle of different dress ore deposit volumes again, and empty wagons includes inspection car etc.), no
Ore deposit amount adjustable spraying amount, waste of resource can be filled according to locomotive.And be easily disturbed, accuracy in detection is low.
A kind of existing patent " high-pressure micro-mist dust suppression equipment ", " a kind of anion suppressing dust with dry mist purification method and device ", " one
Kind intelligent self-cleaning clean dry fog cleaner ", " a kind of double centrifugal dust collection device of dry fog moisture film and its dust collecting process " do not enable
Automatic dust removing effect.Patent " car dumper shed region dry fog cleaner " is to be controlled according to photosensitive sensors, and patent is " a kind of
Dry fog dedusting control system and its control method " carries out auto spraying according to sensor of dust concentration, all haves the shortcomings that above-mentioned,
It is not suitable with iron mine drop shaft environment it is impossible to meet iron mine drop shaft dust removal requirement.
