Embodiment Construction
[0018] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0019] like figure 1 As shown, an air purification system in a railway passenger car includes a compartment (not shown in the figure), and equipment required for air purification is arranged in the compartment, and the equipment includes a high-temperature steam generating device 1, a medicament, an ozone device 2, and a fan 3 One or more of them can be selected according to actual needs. In this embodiment, in order to effectively purify the air in the compartment and remove harmful gases such as formaldehyde and volatile organic substances in the compartment, all the above-mentioned air purification equipment are used.
[0020] Wherein, the high-temperature steam generating device 1 is a high-temperature steam engine, which can generate high-temperature water vapor at about 130° C. and a strong spray force of about 3.2 bar to spray on the surf...

The invention relates to an internal air purification method and an internal air purification system of a railway carriage. The internal air purification method at least comprises the following steps: performing high-temperature steam fumigation on internal goods; spraying and coating medicine on the surfaces of the internal goods so as to decompose harmful gases; performing ozone treatment on internal environment; and performing forced ventilation on the internal environment. According to the internal air purification method and the internal air purification system, the harmful gases such as formaldehyde and volatile organic matters in the carriage can be decomposed, peculiar smells are removed, and disinfection and purification treatments are performed on the space environment, so that the air environment in the carriage can meet the related provision of TB / T1932-2009 Traveler Railroad Train Hygiene and Monitor Technique Provision and then the physical and psychological health of passengers is ensured. The problem that harmful gas in the railway carriage exceeds standard is effectively solved.
Description
technical field [0001] The invention relates to an air treatment method and system, in particular to a method and system for purifying the air inside a railway passenger car, and belongs to the technical field of railway passenger car air treatment. Background technique [0002] In recent years, a large number of new materials and new processes have been used in the manufacturing and installation of railway passenger car interior parts. The materials of some parts themselves contain some free formaldehyde and volatile organic compounds, or materials that are volatile and harmful gases (such as adhesives, paints, etc.) are used in the installation process of the parts, which will cause the parts to volatilize formaldehyde after loading and other harmful gases. At the same time, due to the small space in the car, the airtightness is strong, and the air circulation is slow, which aggravates the accumulation of harmful gases in the car. [0003] According to the relevant provi...
