Vapor-dust drying and separating device

The invention provides a vapor-dust drying and separating device. The vapor-dust drying and separating device comprises a device body, a gas inlet, a primary drying separator, a drying chamber, a secondary drying separator and a gas outlet. According to the vapor-dust drying and separating device, the structure is reasonable, the manufacturing cost is low, the size is small, and the weight is light, so that detection personnel can more conveniently carry and operate the device; through designing a spray nozzle and a collecting probe, large grained liquid droplets can be effectively collected;a condensation effect is further enhanced through a condensation hood, so that a large volume of water vapor in flue gas is removed before entering the drying chamber, and the consumption of a desiccant is effectively lowered; and through designing a cyclone separator, the water vapor is further removed through condensation, broken small desiccant granules can be collected in a dust collecting cupand are prevented from en
