Comprehensive control method and device for urban haze based on condensation and dehumidification of industrial waste gas

Abstract

The invention discloses a comprehensive preventing and treating method and device for urban haze based on condensation dehumidification of industrial exhaust gas. The device comprises an air condenser, a water treatment device and an industrial controller. The industrial controller controls the air condenser according to local wind size, air temperature or precipitation; when the forecasted wind is small below level 2, and the air temperature is low without precipitation, the air condenser is controlled to work to reduce water content of exhaust gas of a thermal power plant and a gas heating furnace, so that the water content in air is reduced and generation of haze is inhibited; when the forecasted wind is greater than level 2, or precipitation happens or the air temperature is relativelyhigh, the air condenser is controlled to stop working or the condensing rate is reduced, exhaust gas rich in water vapor of the thermal power plant and the gas heating furnace is fully or partially discharged, so that the water content of the environment is improved; small water drops adsorb dust microparticles in air, movement in a gale condition is accelerated, and the small water drops and dust microparticles collide and are combined, and are settled automatically under the action of gravity, and therefore, air is purified.

Description

technical field [0001] The invention belongs to the field of comprehensive management of urban environment, and in particular relates to a method and device for comprehensive prevention and control of urban haze based on condensation and dehumidification of industrial waste gas. Background technique [0002] The smog problem in my country's cities has gradually become serious, and has even seriously affected the normal production and life of residents, and it has also brought certain harm to people's health. As far as the current measures to prevent and control smog are concerned, at the national level, emergency measures are mainly adopted, such as suspending and limiting production of some industrial enterprises, suspending work at construction sites, driving with odd and even numbers of motor vehicles, and suspending classes in primary and secondary schools and kindergartens. The life of residents brings a lot of inconvenience, and at the same time, the shutdown of factor...
