Description
One, technical field
The present invention relates to urban subway tunnel environmental technology field, specially a kind of plane jet formula subway tunnel purging is set
It is standby.
Two, background technique
Many facilities are installed in subway tunnel, such as local cable, control cable, signal profession cable, AP antenna, are maked somebody a mere figurehead
Ground wire, headlamp, police leakage cable, signal of communication bracket, communicaton and signal cable, forceful electric power cable bearer, forceful electric power cable, maintenance socket
Case, semaphore, road way signs etc..There are a large amount of groove, gap, pipeline, electric wire etc. (see Fig. 6) between these facilities, and
Size, height, the shape of various facilities are different.Some dusts can be generated in subway train operational process, these dusts
Facility surface in subway tunnel, tunnel inner wall, the groove gap being deposited between the ground and facility of subway tunnel can be adhered to
Interior, as the time extends, dust can be got deeper.
These dusts not only pollute subway tunnel environment, but also influence the normal of electronic monitoring and safety equipment in tunnel
It uses, reduces device sensitivity, increase metro operation rate of breakdown, increase maintenance of equipment cost, influence traffic safety.Subway
The dust rolled in operational process can also be adhered to subway train surface, influence subway train beauty.
Urban rail transit in China development in recent years is swift and violent, to the clean high efficiency of corrective maintenances various in subway tunnel,
More and more necessary highlights, and the ash removing equipment of diversified forms occurs, there are mainly two types of deashing media: high pressure water rinses and compression
Air purging.Due to being equipped with electrical equipment in tunnel, high pressure water, which rinses, to carry out clearly 1.4 meters of subway tunnel regions below
It washes, and increases humidity in tunnel after washing, have certain influence to the facility in tunnel, exist simultaneously cleaning discharge of wastewater and ask
Topic.Compressed air purging air-flow is circular cross section free jet, and compressed-air atomizer hole is tiny, and throughput is small, purge gass flow velocity
Degree decaying is fast, not ideal enough to the purging effect of tunnel inner wall and various facilities far from compressed-air atomizer.
Three, summary of the invention
The purpose of the present invention is provide a kind of plane jet formula for deficiency present in existing subway tunnel ash removing equipment
Subway tunnel purger: first by the plane jet of high speed, the dust at each position in subway tunnel is purged, is passed through later
The dust that dust-extraction unit (12) will be involved in air filters down, and more effectively removes the dust in subway tunnel.
The purpose of the present invention is what is be achieved by the following measures:
Plane jet formula subway tunnel purger include control system (1), axial flow blower assembly (6), pressurizer tank (8),
Air inlet (9), dust-extraction unit (12), purging jet pipe (13), collapsible tube (15), flat nozzle (16), it is characterized in that purging jet pipe
(13) it is mounted on the periphery of pressurizer tank (8), close to railcar limit, the air-flow that axial flow blower assembly (6) is provided, with plane
The mode of jet stream purges the dust in subway tunnel inner wall and tunnel on various facilities.
The purging jet pipe (13) of plane jet formula subway tunnel purger is by flange (14), collapsible tube (15), flat nozzle
(16) group is welded, and for the installation site of flat nozzle (16) outlet close to railcar limit, flat nozzle (16) outlet is long and narrow
The plane jet air directive subway tunnel inner wall of high speed and the various facilities being laid on inner wall are purged its surface by gap
The dust of attachment.
Air inlet (9) outer rim of plane jet formula subway tunnel purger will purge jet pipe close to railcar limit
(13) the plane jet air being discharged and the dust raised suck dust-extraction unit (12) together, and dust is filtered, cleaning
Air come back in subway tunnel.
The control system (1) of plane jet formula subway tunnel purger, drivers' cab (2), Dynamo Room (3), diesel oil hair
Motor group (4), axial flow blower assembly (6), hose adapter 1 (7), pressurizer tank (8), purging jet pipe (13) are mounted on articulated car 1 (5)
On, air inlet (9), hose adapter 2 (10), dust-extraction unit (12), are mounted on articulated car 2 (11), bavin articulated car 2 (11)
Oily generating set (4) provides power supply for plane jet formula subway tunnel purger.
Compared with prior art, the device have the advantages that it is as follows:
1, with use high pressure water as the equipment for cleaning medium compared with, the cleaning of plane jet formula subway tunnel purger is situated between
Matter is the air in tunnel, discharge of wastewater problem is not present, and can clean the dust of all sites in subway tunnel.And it is high
When pressing water as medium is cleaned, the waste water needs after cleaning are cleared up away out of subway tunnel, while being increased after high pressure water cleaning
Humidity in tunnel, to facility in tunnel, there are certain harm.
2, with use compressed air as the equipment for cleaning medium compared with, device efficiency is high, and under identical power, blower is produced
Raw air capacity is the manyfold that compressor generates air capacity.
3, compressed-air atomizer hole is relatively fine, and the air flow velocity attenuation ratio projected from tiny nozzle bore is very fast, right
Dust in subway tunnel inner wall and tunnel far from nozzle on various facilities, purging effect are not ideal enough.And produced by blower
Air capacity it is big, by flat nozzle (16) project air stream be a face, can effectively purge be attached to subway tunnel inner wall and
Dust in tunnel on various facilities.The jet parameters of different jet section can be by the first calculation method of A Bola Abramovich
It determines.
4, the air stream that compressed-air atomizer hole is projected is a filament, and plane jet formula subway tunnel purger
Air stream is a face (see Fig. 3), can cover entire tunnel inner wall.When plane jet formula subway tunnel purger is along subway
When route is mobile, each position in tunnel can be purged to.
