Description

Underground parking garage air purification and new trend device

Technical Field

The utility model relates to the field of garage air treatment equipment, in particular to an air purification and fresh air device for an underground parking lot.

Background

The harmful substances discharged by the automobile in the underground parking garage are mainly carbon monoxide, nitrogen oxides, hydrocarbons and other harmful substances. They originate from the fuel tank, the carburetor and the exhaust system of the automobile, etc. Some gasoline contains tetraethyl lead as antiknock agent, so that the exhausted tail gas contains great amount of lead component, which has 100 times higher toxicity than organic lead and great harm to human body. The speed of combining carbon monoxide in automobile exhaust with hemoglobin in blood is 250 times faster than oxygen, even if trace carbon monoxide is inhaled, the carbon monoxide can cause terrible anoxic injury to people, and the people with mild symptoms can be dizzy and headache, and the brain cells of the people with severe symptoms can be permanently damaged; the nitrogen oxide and the hydrogen oxide can cause the irritative reaction of susceptible people to suffer from eye diseases and laryngitis; benzopyrene contained in the nitrogen-hydrogen compound is a carcinogenic substance, is a high-dispersity particle, can suspend in the air for several days and nights, cannot be discharged after being inhaled by a human body, and is easy to excite to form malignant tumors after being accumulated to a critical concentration.

By comprehensively analyzing the pollutant concentration conditions in the underground parking lot, the concentrations of CO, NOx and PM10 are higher. These three types of pollutants not only cause haze, but also make the atmosphere less visible. A targeted purification method is required to effectively treat the three pollutants. In recent years, methods such as pollution source control, ventilation and dilution and the like are mainly adopted to effectively treat the air pollution problem of underground parking lots, and a good application effect is achieved. However, in the background of urbanization, the number of motor vehicles increases year by year, and the simple treatment method of ventilation and dilution is difficult to completely purify pollutants in underground parking lots, so that many omissions still exist. Aeration dilution can reduce the concentration of pollutants in underground parking lots. When the underground parking lot ventilation system is constructed, the ventilation times and the fresh air volume are increased, and pollutants in the underground parking lot are effectively diluted. Under the condition, the energy consumption is easily increased, and an energy-saving and environment-friendly idea is advocated at other times. Meanwhile, if the indoor environment is poor, the fresh air quantity is increased, and the pollution problem in the underground parking lot is aggravated. Therefore, the method of ventilation and dilution is adopted to purify the air of the underground parking lot, the effect is not obvious, and a good pollutant control effect cannot be achieved.

The specifications in the industry standard of the people's republic of China, namely the civil building green design code are as follows: the underground garage can prevent or reduce the purification of the air inside the warehouse only by calculating the air supply volume not less than 5 times/hour and the air exhaust volume not less than 6 times/hour. The automobile exhaust discharged from the exhaust and exhaust port of the underground parking garage and the smoke discharged from the exhaust port can cause harm to the environment near the export base and people in short distance to different degrees. The air outlet of the underground parking garage project is still arranged near the ground house, even before the window of the building in the main wind direction in summer is closed, when the window of a resident is opened for ventilation, the toxic and odorous waste gas is blown to the resident home from the garage, and the protected object becomes a polluted object.

In order to solve the above problems, the utility model patent with the patent number "CN 201911171156.5" discloses an air purification device for an underground garage, which is installed in the garage, and utilizes a plurality of groups of filter assemblies in the air purification device and a fan to purify the air in the garage, but the device can only be used for a small-sized private underground garage, cannot perform the whole air purification treatment on a large-sized underground garage, and can only perform the purification treatment on local air, and many missed places are easy to be not purified.
