Abstract
The invention provides a method for reducing air pollution caused by vehicles on an urban road and a waste gas purification system. Dust absorption ports are formed along two sides of a road on which vehicles run according to a certain distribution density, a dust discharge channel is formed under a roadbed of the road, each dust absorption port is communicated with the dust discharge channel, and one end of the dust discharge channel is closed and the other end of the dust discharge channel is communicated with the atmosphere; an exhaust fan is arranged at the outlet end of the dust discharge channel; a dust collection device is arranged at the outlet of a fan; and negative pressure is formed in the dust discharge channel when the fan operates, so that the dust absorption ports absorb waste gas and dust produced on the road, the fan discharges the waste gas in the dust discharge channel, and the dust collection device removes dust from the waste gas and then discharges the waste gas into the atmosphere. Waste gas absorption and discharge systems on the two sides of the road operate independently, and the startup and shutdown of each system can be determined according to the wind direction, weather and different time intervals of every day.
Description
Technical field
The present invention relates to a kind of method of urban air purified treatment, specifically, is a kind of method and waste gas purification treatment system of handling when vehicle travels on the urban road waste gas of the dust that produces and vehicular discharge.
Background technology
The dust of kicking up when the waste gas of the vehicular discharge of travels down and vehicle travel in the city is to cause the contaminated one of the main reasons of urban air.Because urban road is an open system, the dust of kicking up when exhaust gas discharged and vehicle travelled when a large amount of passing vehicles travelled can't be handled, and can only let alone atmosphere pollution.At present in the bigger city of China's scale, the factory that toxic emission is relatively the concentrated city of having moved out mostly, or take measures exhaust gas discharged is handled, and still do not have effective processing method by motor vehicles tail gas pollution and the contamination by dust that produces that travel on the road, had a strong impact on the air quality in the city.
Summary of the invention
The present invention is directed to the above-mentioned present situation that can't handle the atmosphere pollution that produces when vehicle travels on the urban road, provide a kind of method and waste gas purification treatment system of handling when vehicle travels on the urban road waste gas of the dust that produces and vehicular discharge, to alleviate degree to atmosphere pollution.
The technical scheme that the present invention deals with problems is as follows:
Road along vehicular traffic is provided with suction port by certain density of arranging on both sides of the road, and the dust discharge passage is set below the roadbed of road, and each suction port is connected with the dust discharge passage, the sealing of dust discharge passage one end, and the other end communicates with atmosphere; The port of export at the dust discharge passage is provided with air exhauster, exit at blower fan is provided with dust arrester, in the dust discharge passage, form negative pressure during the blower fan running, thereby absorb waste gas and the dust that produces on the road by suction port, blower fan is discharged waste gas in the dust discharge passage and enter atmosphere after the dust arrester dedusting.Road waste gas purification treatment system on both sides of the road is separate work, can decide the unlatching of each system or closes according to the different period of wind direction, weather and every day.
The urban road waste gas cleaning system that the present invention proposes can independently be provided with along the road roadside, also can utilize existing drainage system to realize through transforming.When utilizing existing drainage system, ground floor drain is a suction port, and beneath drainage pipeline is through transforming the dust discharge passage as, but the both drainings of improved drainage system, but also exhaust.
Beneficial effect of the present invention is embodied in: it can alleviate because the air pollution that passing motor vehicles cause on the road.
Description of drawings
Fig. 1 is the urban road waste gas cleaning system schematic diagram that the present invention proposes.
Fig. 2 is the A-A profile among Fig. 1.
Fig. 3 is the urban road waste gas cleaning system schematic diagram that utilizes existing drainage system to transform.
In Fig. 1 and Fig. 2: 1 road surface, 2 roadbeds, 3 dust sucting pipelines, 4 suction ports, 5 dust discharge passages, 6 blower fans, 7 dust-removal cloth-bags.
In Fig. 3: 11 flashboards, 12 ground scuppers, 13 ground pipeline next time, 14 underground trunk lines, 15 road surfaces, 16 roadbeds, 17 blower fans, 18 dust-removal cloth-bags.
Below by the specific embodiment, the invention will be further described in conjunction with the accompanying drawings.
Referring to Fig. 1, Fig. 2, by certain density of arranging dust sucting pipeline 3 is set on both sides of the road along the road, the one side near road central authorities on pipeline 3 is provided with suction port 4, and dust discharge passage 5 is set below the roadbed of road; In needing the road section scope of dust discharge, each dust sucting pipeline 3 all is connected with dust discharge passage 5, and each suction port 4 is connected with dust sucting pipeline 3; The sealing of dust discharge passage 5 one ends, the other end leads to ground and communicates with atmosphere; The port of export at dust discharge passage 5 is provided with air exhauster 6, in the exit of blower fan dust-removal cloth-bag 7 is set.When blower fan turns round, in the dust discharge passage, form negative pressure, thereby absorb waste gas and the dust that produces on the roads by suction port 4, blower fan is discharged waste gas in the dust discharge passage and enter atmosphere after the dust-removal cloth-bag dedusting, waste gas in the dust discharge passage flow direction shown in arrow among the figure.Road waste gas cleaning system on both sides of the road is separate work, can decide the unlatching of each system or closes according to the different period of wind direction, weather and every day, for example: rainy day or pollute hour system closing after midnight.
Referring to Fig. 3, utilize the existing drainage system of urban road, it is carried out appropriate reconstruction, can realize under the situation that does not influence draining that urban road waste gas absorbs discharge.Concrete grammar is, two ends at the subdrainage trunk line 14 in the highway section that needs dedusting are provided with flashboard 11 and arm 19, make the subdrainage trunk line be shut in this section two ends gas flow, and water can be by arm 19 proper flow under the flashboard 11, the inboard of trunk line one end of sealing at flashboard 11 is provided with exhaust passage 20,20 exits are provided with air exhauster 17 and dust-removal cloth-bag 18 in the exhaust passage, exhaust passage 20 is connected with trunk line 14, when blower fan 17 runnings, in trunk line 14, form negative pressure, thereby logical time pipeline 13 and ground scupper 12 absorb waste gas and the dust that produces on the road, and blower fan is discharged waste gas in the trunk line and enter atmosphere after the dust-removal cloth-bag dedusting; Waste gas in the dust discharge passage flow direction shown in arrow among the figure.Can be as required, the quantity of setting up the next pipeline 13 of ground scupper 12 and ground by certain density improves exhaust effect.Can decide the unlatching of each system or close according to the different period of wind direction, weather and every day, for example: rainy day or pollute hour system closing after midnight.
