Abstract

The invention belongs to the field of air purification, particularly relates to purification treatment of dusty gas, and discloses a purification method for dusty pressured gas. The method comprises the following steps: firstly, carrying out expansion and speed reduction on the dusty pressured gas to precipitate solid particles in the gas; and then, performing liquid-gas combination treatment on the gas treated in the step 1 so that solid particles in the gas are further dissolved in the liquid, and thus the effect of simply, conveniently and efficiently purifying the dusty pressurized gas ina graded manner is achieved.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a purification method for pressurized gas with dust. Background technique [0002] As building a beautiful home has become a national strategy, the control of dust in environmental issues involves the health of every citizen and has become the focus of people's daily life. The construction industry has been included in one of the main battlefields of air pollution prevention and control, and the problem of dust is the core element of control. Dust and pressurized gas emissions from cement silos and mortar silos on the construction site are the hardest hit areas. At present, most of the dust control measures are taken to isolate the polluted air or suggest to cover the pollution sources. The dust pollution prevention and control measures are very effective. For the lack of air purification equipment that carries dust, especially when the dust is severe, the existing commercial du...
