Abstract

The invention discloses a high-concentration polluted air purification system in an ecotype highway tunnel, comprising an induced draft fan, a preprocessing device and a purification device; the preprocessing device comprises an ozone generator and a humidifier, the purification device comprises a gas-liquid separating cavity, a gas distributing layer and a soil purification layer which are sequentially arranged from bottom to top, a graded aggregate gas distributing layer is arranged on a venting baffle plate at the top part of the gas-liquid separating cavity, an air outlet of the induced draft fan is communicated with the gas-liquid separating cavity by sequentially penetrating the ozone generator and the humidifier; a packing layer of the soil purification layer comprises surface soil,perlite, a pumice stone, peat, humus and microorganism which is used for decomposing the harmful gas in the polluted air; the harmful gas in the polluted air is disposed to the ingredients which areeasy to be absorbed and decomposed by the active soil, the absorption rate of the harmful gas is increased, thereby being beneficial to ensuring the physicochemical property of the active soil, the microbiological activity can be ensured for a long period, the gas is ensured to be evenly distributed in the soil purification layer, and using ratio of the microorganism in the active soil is increased.

Description

technical field [0001] The invention relates to an environmental protection system for purifying air, in particular to an ecological type road tunnel high-concentration polluted air purification system. Background technique [0002] Motor vehicle exhaust pollution is a hot issue of concern in the world today, especially in places and confined spaces where vehicles are concentrated such as highway tunnels, underpasses, underground parking lots, along urban roads, toll stations, etc. Motor vehicle exhaust is not easy to spread. Traffic jams increase air pollution and seriously affect the survival and health of the human body and other living things. In order to solve or reduce the air pollution caused by motor vehicle exhaust, forced mechanical ventilation is usually used in tunnels, underpasses, and indoor parking lots to reduce local pollution, but harmful gases are still discharged into the atmosphere, and there is no pollution to the atmosphere. lighten. There are also m...
