Embodiment 1

[0031] see Figure 1 to Figure 3, the present embodiment provides a liquid dust removal mixing device 3, including a closed container 31 with liquid and a liquid-gas combiner 32, the liquid in this embodiment is water, and the bottom of the closed container 31 is provided with a drain valve 33, the top of the closed container 31 is provided with an exhaust valve 34, the upper part of the side wall of the closed container 31 is provided with a liquid injection pipe 38, and the liquid-gas coupler 32 is set in the closed container 31 Inside, the liquid-gas combiner 32 includes an inlet pipe 325 and a liquid inlet pipe 321, an air suction pipe 322, a liquid-gas mixing pipe 323 and a diffuser pipe 324 connected coaxially in sequence, and the free end of the liquid inlet pipe 321 is an inlet pipe. A liquid port, a filter screen 35 is arranged outside the liquid inlet to filter the liquid entering the liquid-gas combiner 32, a liquid booster pump 37 is provided on the liquid inlet pi...

Embodiment 2

[0040] see Figure 4 to Figure 7 , and see in conjunction with Figure 1 to Figure 3 , this embodiment provides a method for purifying pressurized gas with dust. The difference between this embodiment and the method for purifying pressurized gas with dust in Embodiment 1 is that before using the liquid dust removal mixing device 3, the dust-laden gas is treated. Before the pressurized gas, spray and humidify the dusty pressurized gas through the spray evolution device 2, so that the solid particles in the gas dissolve in water or increase in weight when they meet water and precipitate.

[0041] Preferably, the spray evolution device 2 includes a second airtight container 21, a second inverted container 22, and several pipelines with spray heads 23, and the top of the second airtight container 21 is provided with a first pipeline 4 connected externally. Two air inlets 211, the bottom of the second airtight container 21 is used as a sump, the bottom of the sump is provided with...

Abstract

The invention provides a liquid dedusting and mixing device and method. The device comprises a closed container filled with liquid and a liquid-gas combiner, a drain valve is arranged at the bottom ofthe closed container; an exhaust valve is arranged at the top of the closed container; the liquid-gas combiner is arranged in the closed container; the liquid-gas combiner comprises a gas inlet pipe,a liquid inlet pipe, a gas suction pipe, a liquid-gas mixing pipe and a diffusion pipe, the liquid inlet pipe, the gas suction pipe, the liquid-gas mixing pipe and the diffusion pipe are coaxially connected in sequence. The free end of the liquid inlet pipe is a liquid inlet and provided with a liquid booster pump, the free end of the diffusion pipe is a liquid-gas discharge outlet, and one end of the gas inlet pipe is connected to the gas suction pipe. Pressurized gas with dust and liquid are fully mixed in the liquid-gas combiner; the solid particles with the particle size smaller than 2.5micrometers in gas, namely PM2.5-level micro-particles, are fully fused with water through steam, and PM2.5-level dust and water-soluble harmful substances in the gas are reduced by means of the characteristic that the dust and the water-soluble harmful substances are dissolved in the water.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a liquid dust removal mixing 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 re...
