Description
Technical field
The present invention relates to displaced types to recycle method of ventilation, belongs to technical field of dust removal equipment.
Background technique
With the development of New Technologies, dust pollution object is exhaled from past a large amount of depositing dusts to be increasingly difficult to administer
Dirt conversion, intensive and a large amount of 0.1 μm -2.0 μm of the small particle pollution dust and aerosol that many industrial enterprise's techniques generate
Also many Industrial Enterprise Factory Boundary problem of environmental pollutions and industrial building environment pollution problem, such as environment in workshop are brought
Smoke contamination, chemical contamination and other a variety of toxic and harmful gas pollutions.These it is seriously polluted influence and endanger practitioner's
Health will lead to various disease risks even threat to life.The consequence seriously polluted causes medical treatment to a large amount of enterprises
The problem of burden and practitioner's deficiency, seriously affects production；Dirt pollutant is leaked exhaling in workshop by door and window and ventilation is arranged
It puts and huge negative effect is caused to ambient air PM2.5, traditional industrial enterprise's draft type is mainly by following several:
(1) mode of gravity-flow ventilation is leaned on using roof ventilator.
Disadvantage: rate of ventilation requirement is unable to satisfy when pollutant emission is higher.Winter heating building thermal loss
It is huge, so winter cannot achieve gravity-flow ventilation.
(2) mechanical exhaust is done using powerroof ventilator.
Disadvantage: exhale dust and gas colloidal sol aggregation height usually in 6.5m hereinafter, the ventilation of 8m or more building roof can not solve work
The promotion and ventilation that dirt pollutant is exhaled as area also cause the heating energy for winter northern heating area and largely waste, Wu Fabao
Heating effect is demonstrate,proved, so winter fail to open use.
(3) it adds huge pipeline ventilating system and carries out forced circulation filtering ventilation.
Disadvantage: huge exhaust system will pollute air centralized collection and filter in each workspace, then be sent by huge
Wind system is uniformly sent to workspace, and the 75% of the blower energy causes mass energy to consume for conveying ventilation volume air stream back and forth,
It is more arranged due to ducting system and is limited by structure, there are many air drafts and air-supply blind area, that is, uncontrollable contaminated area.In addition great Qu
The ventilation cost that domain centralized control puts into production for small range or works overtime is higher.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of displaced type recycling method of ventilation, realizes usually big concentrate
The air current composition function for the displaced type air cleaning ventilation that formula system can be only achieved.
Technical scheme is as follows: displaced type recycles method of ventilation, and polluted gas filters ventilation list from displaced type
The air inlet on first top through cartridge filter filtration, surface air cooler heat exchange action after from air outlet be discharged, from air outlet be discharged
Clean gas lift the polluted gas in workshop and be moved upwardly into air inlet.
Further, displaced type filtering ventilation unit includes shell, and filter cylinder, blower are fixed in the shell,
Air inlet is set to the top of shell, and air outlet is set to the lower part of shell.
Further, displaced type filtering ventilation unit includes shell, includes contaminant gases in the shell
Channel, filter cylinder and clean gas passages, the upper part of the housing are equipped with air inlet, and lower part is equipped with air outlet；The filter cylinder setting exists
The inboard of air inlet, the outlet of filter cylinder are connected to clean gas passages, and the end of clean gas passages is connected to air outlet.It is described
Contaminant gases channel be channel between shell and filter cylinder, clean gas passages.
Further, the cartridge openings are downward.
Further, blowback system and blower are provided in the clean gas passages.
Further, confluence ejector pipe, the blowback system packet are equipped between the filter cylinder and clean gas passages
Blowback gas bag and anti-blowpipe are included, the anti-blowpipe is equipped with jet port, and the jet port is located at confluence ejector pipe lower inside.
Further, pollutant flow-path module, the pollutant flow-path module are equipped in the clean gas passages
By pollutant runner modular structure ontology and outer container board group at；
The pollutant runner modular structure ontology includes shape of a saddle top plate and side plate interconnected, the side plate
Side, which is obliquely installed and connects, leads hawk, and the side plate connects ash slot with the bottom for leading hawk；The shape of a saddle top plate point
Fixed blowback gas bag inside angle, the blowback gas bag lower section connect anti-blowpipe, fix surface air cooler and blower between the side plate.
Further, setting collects grey vehicle below the ash slot.
Further, the blower is frequency conversion fan.
Further, surface air cooler is installed above the blower.
Beneficial effects of the present invention are as follows:
(1) present invention makes full use of the gas recycle process of dust removal process, and clean gas is sent into from workshop bottom, thus will
Polluted gas is lifted to be discharged from top, during this pure air with polluted gas there is no mixing, to improve dedusting
The effect of ventilation has also reached energy-efficient purpose.
(2) in equal design air circulation, the present invention is than the rate of ventilation that traditional replacement method of ventilation doubles, i.e.,
If traditional replacement ventilation, which reaches 2 ventilations present invention, can reach 4 rates of ventilation in same air circulation, due to not passing
Defeated power energy consumption more energy saving than traditional replacement method of ventilation 70% or more；In same pollutant occurrence quantity circulated air meter
Under calculation method, proper height arrangement exhaust outlet collect pollutant air circulation be workshop top overhead traveling crane gantry safe distance with
The 80% of outer arrangement exhaust outlet air circulation, fan delivery type selecting parameter reduces by 20%.
(3) large space fresh air switch fresh air flexible arrangement carries out efficient energy conversion with air draft, with displaced type mistake
It filters ventilation unit device and is combined with each other the entire workshop non-blind area supply and exhaust air current composition of realization, purification ventilation effect is best.And one
Secondary property investment is low, and operating cost is low.
