Abstract
The invention provides a steam humidity regulating device, which comprises an inner casing. Flanges are arranged at the two ends of the inner casing. Spiral flow deflectors are evenly wound on the outer wall of the inner casing. An outer casing is arranged outside the spiral flow deflectors. The two ends of the outer casing are fixedly connected with the flanges. The outer casing is provided witha cooling water inlet pipe and a water outlet pipe. A flow regulating valve is arranged on the water inlet pipe. A thin bar with length equal to the length of the inner casing is arranged in the inner casing. Bola-shaped spoilers are evenly welded on the thin bar. The bola-shaped spoilers arranged at the two end parts of the thin bar are fixed with the inner wall of the inner casing. Since the flow deflectors are evenly wound on the outer wall of the inner casing, the cooling water can evenly flow to realize the even cooling of steam in the inner casing, the water drops produced through the condensation of the steam in the inner casing are basically evenly distributed, the magnitude of humidity regulation is controlled only by the opening of a flow control valve on a cooling water pipe, the structure is simple and the operation is easy.
Description
technical field [0001] The invention relates to a steam humidity regulating device, which is an important device for preparing required humidity steam samples in steam humidity measurement and calibration. Background technique [0002] To measure the humidity of flowing steam, the steam humidity must be calibrated first, and to calibrate the steam humidity, steam samples with different humidity must be provided for the experimental needs. At present, there have been many excellent design schemes in humidity regulation technology. For example, the publication number is CN01130105.8, and a utility model patent document titled "Automatically Adjusting Humidity Air-Conditioning Device" discloses a humidity regulating device. It includes an air-conditioning unit composed of an outdoor unit and an indoor unit, and also includes a humidity generator connected with the indoor unit. Its purpose is to realize automatic humidification in heating and cooling mode, automatic dehumidifi...
