Description
The invention belongs to the sanitation of environment technical field, relate to mechanical technique, the dedusting technology of cleaning ground refuse and dust, is the improvement to a kind of watering and lowering dust formula refuse cleaning vehicle.
In arid countries and regions short of rain, stand area, near the zone the building site, industrial dust discharged area that sand and dust attack, street and public place floor-dust amount are quite big.
The excavation muck haulage of building site in the city particularly in the rain, operation behind the rain, is often dropped a large amount of soil and can't be cleared up in the street.Telecommunication line, heat distribution pipeline, greening work and road construction construction are all carried dust to the street directly or indirectly.This is a general phenomenon very in developing country.
The tire of vehicle carries earth from exposed and muddy land for building to road, pulverizes dust on the road or leaf etc., has also dragged several meters high cloud behind car.Often have a large amount of pellets can not sedimentation surplus the arterial highway, urban traffic ten in the scope of rice height, the pellet index be high, and environmental quality is regional much more abominable than the park.
A lot of local tradition in street, park that still keep sweeping with broom by the sanitationman every day.Broom one is crossed and is stirred dust a slice, quite makes us uncomfortable.
The city dust can not get effectively, fully and timely collect, and in the time short of rain, dust is hopeless, just under the stirring of wagon flow or wind circularly with artificial companion.Road dust has become pedestrian's health has the most directly been endangered.
It is very urgent environmental problem that dust pollution is administered in the city.It is address this problem one means the most completely that the street dust is fast and effeciently collected in mechanization.
At present, general in the world mechanization refuse cleaning vehicle has two kinds, and a kind of is small-sized place cleaning cart, and another kind is the large-scale quick road-sweeper of road.
Small-sized place cleaning cart is similar to dust catcher, employing be the way of dust removal by filtration, he can fully clean ground dust.But because filter cloth stops up easily, need clear up dust off and on, clear up untimelyly, the resistance increase of filtration can cause losing the effect of aspirating ground dust.This road-sweeper is the few place of dusty complexion soil amount more compatibly, at the many place meeting frequent jams filter clothes of dust, adds that operating speed is slow, so be difficult to competent road-cleaning.
The quick road-sweeper of road is loaded with large water tank, is equipped with and revolves brush and pulverizing nozzle.During road-sweeper work, revolve brush and paste the ground rotation, rubbish backs, stir dust, pulverizing nozzle is revolving on the brush watering and lowering dust continuously, and dust is partly met water and assembled and revolved brush and put together and collect in the car, and part is fixed to ground by the globule, insufficient or gait of march is too fast because of watering atomizing is directly sucked by the air-introduced machine in the car after being revolved brush and kicking up and be expelled in the air then for part, has objectively played the effect of airborne dust.
Refuse cleaning vehicle can fully clean the rubbish and the grains of sand of bulk, and the actual effect of removing dust is relatively poor.In addition, this cleaning cart is limited to the broad street of cleaning because big loading gage water has occupied big portion vehicle body space, and the car body heaviness causes power consumption big, and the operation distance is limited.
The road refuse cleaning vehicle is a large amount of long-term uses of European countries.Local very good, the airborne dust content of vegetation is very low, and road dust seldom uses this road-sweeper can fully satisfy people's demand.In these years, some domestic large size city imports a lot of external road refuse cleaning vehicles because road dust is many more than European countries, perhaps operating speed is too fast, the effect of cleaning dust is bad.
Fundamentally, over nearly 40 years, be that the backwardness of dedusting technology hampers road machine cleaning dust development of technology and effect.
Chinese patent application 98103451.9 " aerosol centrifugal degradation separating method and device " discloses a kind of centrifuge dedusting technology that has needle rotor (Chinese patent ZL 98201991.2), and it is the breakthrough of efficient dust removal with machine technology.This dedusting technology has that power demand is little, continuous high-efficient dedusting, efficiency of dust collection can be very suitable for vehicle-mounted according to feature dimension, air velocity, rotor speed and characteristics that whether water is adjusted.This dust-removing centrifugal machine technology is applied on the road sweeper, can solve the problem of cleaning dust.
