Embodiment 1

[0032] see Figure 1 to Figure 4 , the present embodiment discloses a method for purifying pressurized gas with dust, comprising the following steps:

[0033] Step 1, expand the volume and reduce the speed of the pressurized gas with dust, so that the solid particles in the gas can be precipitated;

[0034] Step 2: Spray and humidify the gas treated in Step 1, so that the solid particles in the gas dissolve in water or increase in weight and precipitate when meeting water.

[0035]A method for purifying pressurized gas with dust provided by the present invention, firstly, by expanding the volume and reducing the speed of the pressurized gas with dust, the solid particles in the gas are precipitated; and then spraying and humidifying the gas treated in step one , so that the solid particles in the gas dissolve in water or precipitate when they meet water to increase their weight, so as to achieve the effect of simple, efficient, and graded purification of pressurized gas with ...

Embodiment 2

[0051] see Figure 5 to Figure 9 , and can be combined with Figure 1 to Figure 4The difference between the method for purifying pressurized gas with dust in this embodiment and the method for purifying pressurized gas with dust in Embodiment 2 is that the gas treated by the spray purification device 2 is also combined with liquid and gas through the liquid dust removal and mixing chamber 3 Purification treatment, so that the solid particles in the gas are further dissolved in the liquid, the spray purification device 2 is sealed and connected with the liquid dust removal and mixing device 3 through the second pipeline 5, that is to say, the second gas outlet 221 is not used for external connection The exhaust valve 25 is used to discharge the purified gas, but is sealed to the liquid dust removal and mixing device 3 through the second pipeline 5, that is to say, the spray purification device 2 is sealed to the liquid dust removal and mixing device 3 through the second pipelin...

Abstract

The invention belongs to the field of air purification, and provides a method for purifying pressurized gas with dust. The method comprises the following steps: firstly, carrying out expansion and speed reduction on the pressurized gas with dust to precipitate solid particles in the gas; and then, performing spray humidification treatment on the gas so that solid particles in the gas are dissolvedin water or are precipitated by increasing the weight when meeting water, and thus the effect of simply, conveniently and efficiently purifying the pressurized gas with dust in a graded manner is achieved.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a method for purifying 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 dust ...
