The utility model relates to the technical field of
water vapor cooling treatment, in particular to a cooling device of a
water vapor sampler, which comprises a cooling cavity and a
cooling pipe arranged in the cooling cavity, the
cooling pipe comprises a first liquid inlet
pipe, a first liquid outlet
pipe, straight pipes and U-shaped pipes, the plurality of U-shaped pipes are sequentially connected with two adjacent straight pipes so that a passage is formed among the plurality of straight pipes, and the first liquid inlet
pipe is communicated with the first liquid outlet pipe. The upper end and the lower end of the straight pipe are fixed into the cooling cavity through supporting plates, a scraping plate is arranged on the portion, between the two supporting plates, of the straight pipe through a linear driving piece in an up-down moving mode, and a plurality of through holes corresponding to the straight pipes one to one are formed in the scraping plate in a penetrating mode. A second liquid inlet pipe for introducing a
cooling medium and a liquid outlet mechanism are arranged on the outer side wall of the cooling cavity, the
cooling pipe is arranged to be a plurality of straight pipes and U-shaped pipes for connecting two adjacent straight pipes, the flowing path of steam and water can be prolonged, cooling is more sufficient, meanwhile, scale and the like on the surfaces of the straight pipes can be scraped off through scrapers, and the
cooling efficiency is improved. And the heat exchange effect is prevented from being influenced.
