Description

Air purifying agent capable of effectively solving air pollutants in parking place

Technical Field

The invention relates to an air purifying agent, in particular to an air purifying agent capable of effectively solving air pollutants in parking places.

Technical Field

In recent years, with the continuous development of urban modern construction, the number of small and medium-sized automobiles used in urban traffic is rapidly increasing. At present, the urban area mainly solves the problem of difficult parking by building underground parking lots, particularly in the territories of the central urban areas of various cities.

However, the large underground parking lot is underground, so that the ventilation performance is poor, and in addition, a large amount of incompletely combusted tail gas is discharged when a vehicle enters or exits the large underground parking lot and is braked, idled and started, so that the large underground parking lot becomes a zone where the tail gas of the vehicle is most concentrated. Some scholars study and understand that in large underground parking lots with severe ventilation conditions, the scholars feel dizziness, headache, nausea and dyspnea in a short time through special research on representative large underground parking lots. Even if a certain ventilation facility is arranged, workers who need to stay in a large underground parking lot for a long time generally feel sore throat, lack of strength, skin allergy and susceptibility to cold.

The automobile exhaust pollutants mainly comprise: carbon monoxide, nitrogen oxides, sulfur dioxide, smoke particles, odor (formaldehyde, etc.), wherein nitrogen oxides are mainly nitrogen monoxide and are easily formed into nitrogen dioxide. The underground parking lot mainly contains CO and NO generated by incomplete combustion of fuel oil caused by starting, stopping and slow running_x，SO₂And TVOC, various bacteria bred due to the closed moisture of underground environment and dust particles such as PM10, PM2.5 and the like contained in large amount in polluted air. In parking places where air convection cannot be formed, only a ventilation system is adopted to carry out ventilation on the parking places.

In view of the situation, the invention provides the air purifying agent which can effectively solve the air pollutants in the parking place.
