Method for reducing pollutant concentration and improving air quality in new vehicle

Abstract

The invention discloses a method for reducing the pollutant concentration and improving the air quality in a new vehicle, including the following steps: (A) raising the temperature inside the new vehicle to 35-60 DEG C by using an automobile air conditioning; (B) absorbing harmful substances in the interior air of the vehicle by using an air purification device. The air purification device comprises a shell; a prefilter membrane and a fan are arranged at the position near air inlets of the shell; the other end, opposite to the end provided with the air inlets, of the shell is provided with air outlets; a first adsorption layer, a photocatalysis device and a membrane absorption device are arranged inside the shell; the photocatalysis device is provided with fluorescent lamps and photocatalysis layers on two inner sides of the shell; a rotation shaft, which is controlled by a micro-motor, and polyethersulfone hollow fiber membranes are arranged in the membrane absorption device; an absorbent inlet and an absorbent outlet are arranged on two sides of the membrane absorption device.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for reducing the concentration of pollutants in a new car and improving the air quality in the car. Background technique [0002] With the rapid development of my country's national economy and the improvement of people's quality of life, the sales of passenger cars have increased year after year. The convenience brought by the use of cars to people's lives is self-evident. The popularization and use of automobiles brings some negative things that are more and more seriously affecting people's lives. Among them, the most important thing that cannot be ignored is the chemical and toxic substances contained in automobile parts, interior decoration, etc. hazards to the health of the people. The air components in the car contain substances harmful to the human body, such as formaldehyde, benzene series, TVOC and other harmful gases, and some bacteria and viruses in the ca...

Problems solved by technology

Although my country has promulgated and implemented the "Guidelines for the Evaluation of Air Quality in Passenger Cars", from manufacturing parts to interior configuration, due to multiple reasons such as cost or sales, automobile companies cannot guarantee the safety and non-toxicity of all supporting materials , so the control of air pollutants in the car has become a point that car buyers must pay attention to.

[0003] At present, for the control of pollutants in the car, due to individual differences among car owners, some use perfume or air fresheners to cover up the peculiar smell in the car, but this practice does not actually work, and may even aggravate the harm of harmful substances. Most of the car owners will use special air purification devices. Currently, there are advantages and disadvantages in the existing in-car purification methods, including simple activated carbon adsorption, biological adsorption, photocatalytic technology, etc., but generally have low adsorption efficiency, serious secondary pollution, and technical Issues such as immature application
