Automatic transposition side-draught exhaust gas suction device

Abstract

The invention discloses an automatic transposition side-draught exhaust gas suction device, comprising tracks arranged in a workshop and trolleys which are driven by a power mechanism and can travel on the tracks, wherein the trolley is fixedly provided with a horizontal type cylindrical suction hood; one end of the suction hood is sealed, and the other end thereof is provided with an exhaust gasinlet; the bottom part of the suction hood is communicated with an air outlet duct of which the opening and closing are controlled by a control valve along the radial direction; the lower end of the air outlet duct is communicated with a bag type dust collector system arranged outside the workshop through a geosyncline; the upper end of the air outlet duct extends to the inner cavity of the suction hood, and the inlet of the air outlet duct is provided with a filter screen; the end part provided with an exhaust inlet of the suction hood is provided with a photoelectric switch; the track is provided with a travel switch for determining the stop position of the trolley; and the photoelectric switch, the travel switch, the power mechanism, the control valve and the bag type dust collector are connected with a PLC controller through cables.

Description

Technical field: [0001] The invention relates to an exhaust gas dust collection device, in particular to an automatic transposition side suction type exhaust gas dust collection device. Background technique: [0002] According to the 2008 China Environmental Status Bulletin issued by the Ministry of Environmental Protection of the People's Republic of China on June 4, 2009, the air quality of cities across the country is generally good, which has improved compared with the previous year, but some cities are still heavily polluted; the distribution of acid rain in the country remains stable, but acid rain Pollution is still heavy. In 2008, 519 cities across the country reported air quality data, 21 cities (accounting for 4.0%) meeting the first-class standard, 378 cities (accounting for 72.8%) meeting the second-class standard, and 113 cities (accounting for 72.8%) meeting the third-class standard 21.8%), 7 cities (accounting for 1.4%) inferior to the third-tier standard.
