Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.

3 formula spraying dedusting device of Venturi tube provided by the utility model includes shell 1, collecting tank 2, Venturi tube 3, spray First 4 and spray head pipeline 5, the collecting tank 2 of opening upwards is fixed in shell 1, several Venturi tubes 3 both pass through the setting of collecting tank 2, The top of each Venturi tube 3 is equipped with a spray head 4 accordingly, each spray head 4 is connected with spray head pipeline 5.

3 formula spraying dedusting device working principle of a kind of Venturi tube provided by the utility model is:

Flue gas is flowed up from shell 1, when by the Venturi tube 3 that is worn on collecting tank 2, each Venturi tube 3 The water spray of spray head 4 that top is correspondingly arranged captures particulate matter, and clean flue gas is continued up to be discharged via at the top of shell 1, is captured The moisture and particulate matter to get off imports in collecting tank 2.

The particulate matter solution collected in collecting tank 2 in order to prevent overflows collecting tank 2, further includes being arranged across collecting tank 2 The top of overflow pipe 6, overflow pipe 6 is equipped with overflow port 7.

In order to Venturi tube 3 is located at the top in collecting tank 2 respectively and the lower part outside collecting tank 2 is fixed, often One Venturi tube 3 is fixed by upper fixed stiffening plate 8 and lower fixed stiffening plate 9 between each other.
