Description
Technical field
The invention belongs to ventilation equipment technical fields, specifically, being related to removing for a kind of ventilation shaft air outlet or air inlet
Dirt device and its dust removal method.
Background technique
Ventilation equipment are widely used in various fields, for example, industry, the heating of construction, ventilation and system
It is cold；All various aspects such as the air exchange of refrigerator, air-conditioning etc., Electronic cooling in life house.
For example, due to the closing of tunnel internal environment and humidity, can also be gathered in partial region in the application scenarios in tunnel
Sewage and dirt, especially under the scenes such as constructing tunnel, construction of subway when explosive charge, the use of internal combustion engine, excavation in stratum
Release pernicious gas, it is therefore desirable to open blower and ventilation is aerated to tunnel internal.When wagon flow in tunnel by when or work
When making personnel and working in tunnel, it is required to ventilation equipment and working condition is kept to take a breath constant ventilation in tunnel.For another example in base
It builds in (such as subway, hospital public place) scene, to keep the air exchange in relative closure environment, also widely applies ventilation
Air regenerating device.
In above-mentioned scene, when air passes through existing circulation path under blower drive, the ash in tunnel also will drive
Dirt is accumulated in ventilation shaft, can be caused adverse effect to the ventilation effect of ventilation equipment in this way, even be damaged blower body, contracting
Its short service life.
In the prior art, the dust-extraction unit of ventilation shaft is often provided at air outlet, existing to utilize electrostatic precipitation net
The mode being dusted is that can be adsorbed when blower starts and blows out wind by the dust of electrostatic precipitation net, removes to realize
Dirt function, but the dust accumulation of electrostatic precipitation net itself thereon is also required to further clear up.First is that being removed using electrostatic
The accumulation of the online dust granule of dirt makes dust volume become larger, Automatic-falling after weight becomes larger, but will lead to dust in this way and accumulated
The ventilation quantity that ventilation shaft is reduced in journey, influences ventilation requirement；Second is that increasing air quantity wind speed or installation using the blower of itself
Additional dust-removing equipment blows down the dust of electrostatic precipitation net, but it is higher to the requirement of blower in this way cause cost higher,
Additional blower, which also results in, occupies ventilation shaft volume, power supply structure complexity, further increases cost；Third is that manually to electrostatic
Basket strainer carries out periodic cleaning, this needs to dismantle basket strainer manually, and cleaning, cleaning efficiency are low, time-consuming and laborious.
Patent CN207131605U (document 1) discloses a kind of scheme of displaced type ventilation device using geothermal energy,
Enter the displaced type ventilation dress using geothermal energy using the dust granule that the electrostatic precipitation net being arranged in inside air duct obstructs the external world
Set inside.But the electrostatic precipitation net of which is detachably secured to air duct, needs to remove thereon after removing electrostatic precipitation net
Dust accumulation, cleaning efficiency is low.Further, since document 1 uses manual clean mode, therefore it not can appreciate that the prior art
The dust of middle electrostatic precipitation net usually accumulates more problems in partial portion, can not also further realize intelligent control, higher
Effect ground cleaning dust accumulation.
Therefore, how under the premise of guaranteeing ventilation effect, cleaning efficiency and the cleaning of ventilation equipment dust-extraction unit are improved
Effect, while save the cost are a technical problems urgently to be resolved.
