Embodiment 1

[0034] see Figure 1 to Figure 2 , this embodiment discloses a gravity sedimentation device 1, comprising a first airtight container 11 and a first inverted container 12, the top of the first airtight container 11 has a first air inlet 112, and the first airtight container 11 The bottom of the settling residue recovery port 113 is opened, the first inverted container 12 is an inverted U-shaped structure, and the first inverted container 12 is coaxially arranged in the first airtight container 11, and the top of the first inverted container 12 Open the first air outlet 121, the bottom opening of the first inverted container 12 is set, the flow cross section of the first inverted container 12 is greater than or equal to the flow cross section of the channel between the first airtight container 11 and the first inverted container 12, The gas under pressure with dust, that is, the gas to be treated, enters the inside of the first airtight container 11 through the first air inlet 1...

Embodiment 2

[0041] see Figure 3 to Figure 4 , and please combine Figure 1 to Figure 2 , the pressurized gas purification method of the present embodiment has the following differences compared with the first embodiment:

[0042] In the pressurized gas purification method of this embodiment, the gas treated by the gravity precipitation device is sprayed and humidified through the spray purification device. The spray purification device 2 includes a second airtight container 21, a second inverted container 22, and several The pipeline of the head 23, the top of the second airtight container 21 offers a second air inlet 211, the second air inlet 211 is connected with the first air outlet 121 of the spray purification device 1 through the first pipeline 4, the first The bottom of the two airtight containers 21 is used as a sump, the bottom of the sump is provided with a first waste water discharge valve 24, the second inverted container is an inverted U-shaped structure, and the second inv...

Embodiment 3

[0053] see Figure 5 to Figure 9 , and can be combined with Figure 1 to Figure 4 The difference between the pressurized gas purification method of this embodiment and the second embodiment is that the gas treated by the spray purification device 2 is also subjected to liquid-gas combination purification treatment through the liquid dust removal and mixing chamber 3, so that the solid particles in the gas are further dissolved in the 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 externally connected to the exhaust valve 25 for discharging the purified gas, but The second pipeline 5 is in sealing connection with the liquid dust removal and mixing device 3 , that is to say, the spray purification device 2 is in sealing connection with the liquid dust removal and mixing device 3 through the second pipeline 5 .

Abstract

The invention provides a gravity type precipitation device and method. The gravity type precipitation device comprises a first closed container and a first inverted container; the first inverted container is of an inverted U-shaped structure; the first inverted container is coaxially arranged in the first closed container, a first air outlet is formed in the top of the first inverted container; anopening is formed in the bottom of the first inverted container; the first inverted container with an inverted U-shaped structure is coaxially arranged in the first closed container; under the condition that the same expansion volume is realized, the structure is more compact, the required occupied area is smaller, and the speed reduction efficiency of gas is higher. in addition, the through-flowcross section of the first inverted container is larger than or equal to the through-flow cross section of the channel between the first closed container and the first inverted container, and the defect of secondary acceleration caused by the fact that the through-flow cross section of the airflow channel is decreased from large to small is overcome.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a gravity sedimentation device and method. 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 removal...
