Description
Technical Field
The invention relates to a streamline flow guiding device and method, in particular to a streamline flow guiding device and method for a high-speed mixed bed.
Background
At present, most of domestic water inlet and distribution devices of high-speed mixed beds (the running flow rate is 100-120 m/h) in China adopt a form of baffle plates and porous plate water caps. The baffle is adopted as a first-stage water distributor, and the perforated plate water cap is a second-stage water distributor. Because the baffle is too simple, the one-level water distribution effect is poor, and the baffle can not adapt to different flow rates. The porous plate water cap is easy to block, so that the secondary water distribution effect cannot be ensured, and the local resistance of the porous plate is easy to be overlarge to deform and damage. Therefore, the high-speed mixed bed water inlet and distribution device has congenital defects, and the use performance is natural and cannot be guaranteed. According to incomplete statistics, the high-speed mixed bed adopting the form to distribute the inlet water has the problems that the quality of the outlet water is unstable and the periodic water production amount is lower when more than 80 percent of the inlet water is distributed. The problem is particularly remarkable in a condensate fine treatment system of a supercritical and ultra-supercritical thermal power generating unit in China, and the stability of the quality of water vapor of the supercritical and ultra-supercritical thermal power generating unit and the fine treatment operation economy are obviously influenced. In order to solve the problem completely, a novel water inlet and distribution device which can adapt to the characteristics of high running flow rate, low water cushion layer and the like of a high-speed mixed bed needs to be developed so as to replace the high-speed mixed bed water inlet and distribution device of the baffle plate and the multi-hole plate water cap which are commonly used at present.
