Urban air duct process for building air haze treatment

Abstract

The invention relates to the technical field of haze treatment, in particular to an urban air duct process for building air haze treatment. The process comprises the following steps that (1) ventilating ducts are constructed, specifically the ventilating ducts are constructed beside buildings, and solar panels are arranged at the top ends of the buildings where the ventilating ducts are constructed; (2) haze atmosphere is introduced, specifically the atmosphere is introduced from the bottom ends of the ventilating ducts through induced draft fans and flow upwards in the ventilating ducts; (3)haze particles and harmful substances are removed, specifically water vapor spraying devices are arranged at the middle-upper portions of the ventilating ducts; and (4) filtering devices operate, specifically the filtering devices adsorb and filter untreated particulate pollutants in air. According to the urban air duct process for building air haze treatment, haze can be treated, so that the airpollution is reduced; the occupied area is reduced; and the energy consumption is reduced, so that the cost is saved.

Description

Technical field [0001] The invention relates to the technical field of smog treatment, in particular to an urban air duct process for air smog treatment of buildings. Background technique [0002] As we all know, haze weather is a state of air pollution, which is a general expression of the excessive content of various suspended particulates in the atmosphere, especially PM 2.5 is considered the culprit of haze weather. In view of the pollution of haze to the ambient air, atmospheric haze control is imperative. [0003] At present, there are two ways to deal with haze weather. One is artificial rainfall. Although artificial rainfall has a certain effect, it cannot be implemented on a large scale, and it is easily affected by changes in the weather. It is convenient to carry out artificial rainfall, and the artificial rainfall equipment covers a large area and has a high cost; the other is to control enterprises to discharge exhaust gas in accordance with exhaust gas emission stand...

Problems solved by technology

[0003] There are two ways to deal with fog and haze weather. One is artificial rainfall. Although artificial rainfall has a certain effect, it cannot be implemented in a large area, and it is easily affected by weather changes. It is convenient for artificial rainfall, and the artificial rainfall equipment covers a large area and the cost is high; the other is to control the exhaust gas emission of enterprises in accordance with the exhaust gas emission standards, or directly shut down polluting enterprises. The amount of pollution will inevitably increase the cost of enterprises and increase the burden on enterprises. Most enterprises are unwilling to bear this part of the investment, or they cannot bear this part of the cost due to limited profits. The national economy has caused immeasurable losses, and the effect of this governance method is not significant, which requires us to explore a low-cost, effective method of haze control
