Embodiment 1

[0034] see Figure 1 to Figure 2 , this embodiment discloses a gravity type sedimentation device 1, including a first airtight container 11 and a first inverted container 12, the top of the first airtight container 11 is provided with a first air inlet 112, the first airtight container 11 The bottom of the container is provided with a precipitation residual material recovery port 113, the first inverted container 12 is an inverted U-shaped structure, the first inverted container 12 is coaxially arranged in the first airtight container 11, and the top of the first inverted container 12 A first air outlet 121 is opened, the bottom opening of the first inverted container 12 is provided, and 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 dusty gas under pressure, that is, the gas to be treated, enters the first airtight conta...

Embodiment 2

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

[0042] The pressurized gas purification method of this embodiment performs spray humidification treatment on the gas treated by the gravity type precipitation device through the spray purification device. The spray purification device 2 includes a second airtight container 21, a second inverted container 22 and several The pipe of the head 23, the top of the second airtight container 21 is provided with a second air inlet 211, the second air inlet 211 is connected to the first air outlet 121 of the spray purification device 1 through the first pipeline 4, and the second air inlet 211 is connected to the first air outlet 121 of the spray purification device 1. The lower part of the second airtight container 21 is used as a water collection tank, the bottom of the water collection tan...

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 in this embodiment and the second embodiment is that the gas treated by the spray purification device 2 is also subjected to a combined liquid-gas purification treatment through the liquid dust removal mixing chamber 3, so that the solid particles in the gas are further dissolved in the gas. In the liquid, the spray purification device 2 is sealedly connected to the liquid dust removal mixing device 3 through the second pipeline 5, that is to say, the second air outlet 221 does not have an external exhaust valve 25 for discharging purified gas, but The second pipeline 5 is sealed with the liquid dust removal and mixing device 3 , that is to say, the spray purification device 2 is sealed with the liquid dust removal and mixing device 3 through the second pipeline 5 .

[0054] The liquid dust removal and mixing device 3 includes a thir...

Abstract

The present invention provides a gravity sedimentation device and method. The gravity sedimentation device includes a first airtight container and a first inverted container. Since the first inverted container is an inverted U-shaped structure, and the first inverted container is coaxially arranged on the In the first airtight container, the top of the first inverted container is provided with a first air outlet, and the bottom of the first inverted container is opened. By coaxially setting the first inverted container in an inverted U-shaped In the first airtight container, under the condition of achieving the same expansion volume, the structure can be more compact, the required floor area is smaller, and the gas speed reduction efficiency is higher. In addition, the flow cross section of the first inverted container is larger than It is equal to the flow section of the channel between the first airtight container and the first inverted container, avoiding the disadvantage of secondary acceleration caused by the change of the flow section of the airflow channel from large to small.

Description

technical field [0001] The present invention relates to the field of air purification, in particular to a gravity type sedimentation device and method. Background technique [0002] As the construction of beautiful homes has become a national strategy, dust control 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 as one of the main battlefields for air pollution prevention and control, and the dust problem is the core element of control. Cement silos, mortar silos, etc. on the construction site are the hardest hit areas. At present, the most frequently adopted dust control measures are usually to isolate the polluted air or suggest covering the pollution source. The means of dust pollution prevention and control are very effective. For the lack of air purification equipment carrying dust, especially when the dust is serious, the current commercial dust removal equipment...
