Intelligent purification device for contaminated air in underground space

Abstract

The invention relates to an intelligent purification device for contaminated air in underground space and belongs to the technical field of air purification. The intelligent purification device comprises an intelligent control system as well as a primary filter, a dust removing system, an air valve and a fan which are sequentially arranged in a ventilation duct in the air inlet direction, wherein the dust removing system comprises an electrostatic precipitator and a cleaning device, and the cleaning device comprises nozzles communicated with a water pump; the intelligent control system collects related information of the contaminated air through setting of a pressure meter I, a dust concentration sensor I, a temperature sensor, a humidity sensor, an air speed testing instrument, a smoke transmittance sensor, a pressure meter II, a dust concentration sensor II, a pressure meter III and a dust concentration sensor III, the related information is sent to a microprocessor and calculated and processed by the microprocessor, then control signals are generated, and accordingly, voltage of the electrostatic precipitator as well as corresponding parts such as the cleaning device, the air valve, the fan and the like is controlled. With the adoption of the intelligent purification device, the contaminated air in the ventilation duct can be effectively purified.

Description

technical field [0001] The invention relates to an intelligent purification device for underground space polluted air, which belongs to the technical field of air purification. Background technique [0002] With the rapid development of the transportation industry in the national economy, the number of road tunnels, urban tunnels, and subways is increasing, and the number of long mountain road tunnels (tunnels with a length of more than 6 kilometers) is also increasing. For long tunnels, incomplete combustion of automobiles and diesel vehicles during driving will produce high concentrations of polluting gases, mainly including particulate matter PM, carbon monoxide CO, nitrogen oxides NOX, hydrocarbons HC, sulfur dioxide SO2, etc. A perfect and reliable ventilation system is a necessary condition to ensure the safe operation of long highway tunnels, urban tunnels and subways. [0003] At present, in China, the ventilation methods for highway tunnels, urban tunnels, an...

AI Technical Summary

Problems solved by technology

[0003] At present, in China, the ventilation methods of highway tunnels, urban tunnels, and subway operation ventilation configurations are inseparable from the ventilation ducts formed by inclined shafts, vertical shafts, and parallel guide tunnels. The construction of inclined shafts and vertical shafts causes damage to mountain vegetation, resulting in There is an obvious conflict between the construction and development of mountain expressways and the protection of the green environment, and although the high-altitude emission treatment method can effectively reduce the air pollution in the tunnel, it is only physical dilution, which cannot achieve the purpose of purification and treatment. Distributed in the atmospheric environment around the tunnel, it will pose a continuous hazard to the health of surrounding residents and the ecological environment
