Embodiment 1

[0040] see figure 1 , this embodiment provides a spray purification device, including a closed container 21, an inverted container 22 and a number of pipes with a spray head 23, the top of the closed container 21 is provided with an air inlet 211, the closed container 21 The lower part of the container 21 is used as a sump, the bottom of the sump is provided with a first waste water discharge valve 24, the inverted container is an inverted U-shaped structure, and the inverted container 22 is coaxially arranged in the closed container 21, so The cross-sections of the inverted container 22 and the closed container 21 are circular, the top of the inverted container 22 is provided with an exhaust port 221, and the bottom of the inverted container 22 is opened at the bottom. The gas to be treated enters the closed container 21 through the air inlet 211, passes through the channel between the closed container 21 and the inverted container 22, flows into the inverted container 22 fro...

Embodiment 3

[0054] see Figure 2 to Figure 3 The difference between the pressurized gas purification method provided in the third embodiment and the second embodiment is that before using the spray purification device 2 to process the dust pressurized gas, that is, the gas to be treated, the gravitational precipitation device 1 is used to expand the capacity of the gas to be treated. At a high speed, solid particles with a particle size of 10-100 μm in the gas are precipitated, and the gravity type precipitation device 1 is sealedly connected to the spray purification device 2 through the first pipeline 4 .

[0055] Preferably, in the above-mentioned spray purification device, the gravity type sedimentation device 1 includes 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 The bottom of the first airtight container 11 is provided with a precipitation residual material recovery port 113. ...

Embodiment 4

[0061] see Figure 5 to Figure 9 , and can be combined with Figure 1 to Figure 4 The difference between this embodiment and the third embodiment is that the gas treated by the spray purification device 2 is also subjected to a combination of liquid and gas purification treatment through the liquid dust removal and mixing device 3, so that the solid particles in the gas are further dissolved 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 exhaust port 221 does not have an external exhaust valve 25 for discharging the purified gas, but passes through the second pipeline 5. It is sealed with the liquid dust removal mixing device 3 , that is to say, the spray purification device 2 is sealed with the liquid dust removal mixing device 3 through the second pipeline 5 .

[0062] The liquid dedusting and mixing device 3 includes a second airtight container 31 with liquid...

Abstract

The invention belongs to the field of air purification and provides a spray purification device and method. The device includes a closed container, an inverted container and several pipes with spray heads. The lower part is used as a sump, and the bottom of the sump is equipped with the first waste water discharge valve. The inverted container is an inverted U-shaped structure, and the inverted container is coaxially arranged in the closed container. The top of the inverted container is provided with an exhaust port. The inverted container The bottom opening of the container is set, and the inner wall of the closed container and the inner and outer walls of the inverted container are respectively provided with a number of pipes with spray heads, and the water in the sump is pumped to each spray head by a pressure pump. Humidify the pressurized gas with dust through the spray head, so that the solid particles with a particle size of 2.5-10 μm in the pressurized gas with dust will increase in weight when they meet water and precipitate or the dust will dissolve in water to achieve the purpose of purifying the air.

Description

technical field [0001] The present invention relates to the field of air purification, in particular to a spray purification 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 is too ...
