Embodiment 1

[0032] see Figure 1 to Figure 4 , this embodiment discloses a device for purifying pressurized gas with dust. In this embodiment, the pressure of the pressurized gas with dust is 0.05-0.3 MPa. The device includes: a primary gravity sedimentation bin 1 and a secondary spray Purification bin 2, the first-level gravity sedimentation bin 1 is sealed and connected with the second-level spray purification bin 2 through the first pipeline 4, and the pressurized gas with dust passes through the first-level gravity sedimentation bin 1 and the second-level spray purification bin 2 in sequence , the first-stage gravity sedimentation bin 1 can expand the volume and reduce the speed of the dust pressurized gas to precipitate the solid particles in the gas, and the second-stage spray purification bin 2 can spray the dust pressurized gas to make the solid particles in the gas Dissolve in water or increase in weight when meeting with water and precipitate.

Embodiment 2

[0049] see Figure 5 to Figure 9 , and can be combined with Figure 1 to Figure 4 The difference between this embodiment and Embodiment 1 is that the second gas outlet 221 is not externally connected to the exhaust valve 25 for discharging the purified gas, but is sealed and connected with the three-stage liquid dust removal mixing chamber 3 through the second pipeline 5 That is to say, the secondary spray purification chamber 2 is sealed and connected with the tertiary liquid dedusting mixing chamber 3 through the second pipeline 5 .

[0050] The three-stage liquid dedusting mixing chamber 3 includes a third airtight container 31 provided with liquid (in this embodiment, water is used) and a liquid-gas combiner 32, and the bottom of the third airtight container 31 is provided with a second waste water discharge valve 33 , the top of the third airtight container 31 is provided with an exhaust valve 34, the upper part of the side wall of the third airtight container 31 is prov...

Abstract

The invention belongs to the field of air purification. In view of the lack of existing air purification equipment carrying dust, especially the problem that the existing dust removal equipment cannot adapt to the construction site of the construction industry when the dust is severe, the invention provides a device for purifying pressurized gas with dust , including: a first-level gravity sedimentation bin and a second-level spray purification bin, the first-level gravity sedimentation bin is sealed and connected to the second-level spray purification bin through the first pipeline, and the pressurized gas with dust passes through the first-level gravity sedimentation in turn bin and the secondary spray purification bin for graded purification treatment, the first-level gravity sedimentation bin can expand the capacity and reduce the speed of the dust under pressure gas to precipitate the solid particles in the gas, and the second-level spray purification bin can pressurize the dust The gas is sprayed to make the solid particles in the gas dissolve in water or precipitate when it meets water to increase its weight, so as to achieve the effect of simple, efficient, and graded purification of pressurized gas with dust.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a device 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 ...
