Description

TECHNICAL FIELD

[0001] The utility model relates to dust remover technical field especially relates to a kind of for dust remover spray cooling device. BACKGROUND

[0002] Dust remover is the equipment called dust remover or dust removal equipment that separates dust from flue gas.Dust remover performance is expressed by the amount of gas that can be handled, the resistance loss when the gas passes through the dust remover and the dust removal efficiency. Dust remover is a common facility in boiler and industrial production. Dust is all solid small particles that can exist in air for a long time. It is a dispersion system called aerosol. Air is the dispersion medium, and solid particles are the dispersed phase. Dust remover is a device that separates such small solid particles from aerosol. During the dust removal process, the dust remover is easily damaged and its service life is reduced due to the large amount of heat in the flue gas.
