In the figure: 1. a boiler; 2. a smoke dust treatment device; 3. a spray tower; 4. a control cabinet; 5. a pool; 6. an induced draft fan; 7. a first conduit; 8. a helical conduit; 9. a second conduit; 10. a gas pH detector; 11. a tail gas discharge pipe; 12. a nozzle; 13. an atomizing spray head; 14. a third pipeline; 15. a water pump; 16. a liquid pH detector; 17. a discharge pipe.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

Examples

As shown in fig. 1, the utility model provides a boiler tail gas purification device, including boiler 1, boiler 1 is connected to smoke and dust processing apparatus 2 through first pipeline 7, smoke and dust processing apparatus 2 is connected to the lower part of spray column 3 through second pipeline 9.

The smoke treatment device 2 is mainly used for removing particulate matters in the tail gas of the boiler 1 and comprises a shell, wherein a vertically arranged spiral pipeline 8 is arranged in the shell, activated carbon adsorption particles are filled in the spiral pipeline 8, the bottom of the spiral pipeline 8 is connected with a first pipeline 7, and the top of the spiral pipeline 8 is connected with a second pipeline 9.

Be equipped with spray set in the spray column 3, spray set is used for cooling down 1 tail gas of boiler, improves tail gas PH value simultaneously, and it is in including setting up spray tube 12 and the equidistant setting at spray column 3 top a plurality of atomizer 13 on the spray tube 12, spray tube 12 is connected to through third pipeline 14 suction pump 15.
