A streamlined diversion device and method for high-speed mixed bed

Abstract

The invention discloses a streamlined flow guide device and method for a high-speed mixed bed, which comprises a high-speed mixed bed shell, a connecting cylinder arranged in the high-speed mixed bed shell and distributed sequentially from top to bottom, a streamlined flow guide side plate, Streamlined flow deflector, resin layer and porous plate, wherein, the top of the high-speed mixed bed shell is provided with a high-speed mixed bed inlet, the bottom of the high-speed mixed bed shell is provided with a high-speed mixed bed outlet, and the middle part of the streamlined flow guide side plate is provided with a A plurality of first through holes, the lower end of the connecting cylinder communicates with the first through hole, the upper end of the connecting cylinder communicates with the inlet of the high-speed mixed bed, and the middle part of the streamlined deflector is provided with a streamlined flow distribution structure, and the streamlined flow distribution structure passes through After being inserted into the connecting cylinder through the first through hole, it faces the inlet of the high-speed mixed bed; a number of second through holes are opened on the streamlined deflector plate, and the device and method can effectively improve the water distribution effect of the high-speed mixed bed.

Description

technical field [0001] The invention relates to a streamlined flow guide device and method, in particular to a streamlined flow guide device and method for a high-speed mixed bed. Background technique [0002] At present, most of the domestically produced high-speed mixed bed (running flow rate 100-120m / h) water inlet and distribution devices in China adopt the form of baffle plate and perforated plate water cap. In this form, the baffle is used as the primary water distributor, and the perforated plate water cap is used as the secondary water distributor. Because the baffle is too simple, the first-stage water distribution effect is very poor, and it cannot adapt to different flow rates. The perforated plate water cap is easy to block, so that the secondary water distribution effect cannot be guaranteed, and the local resistance of the perforated plate is too large to cause deformation and damage. It can be seen that this type of high-speed mixed bed water inlet and distr...

Problems solved by technology

Because the baffle is too simple, the first-stage water distribution effect is very poor, and it cannot adapt to different flow rates

The water cap of the perforated plate is easy to block, so that the secondary water distribution effect cannot be guaranteed, and it is easy to cause deformation and damage of the perforated plate due to excessive local resistance.

It can be seen that this type of high-speed mixed bed water inlet and distribution device has congenital defects, and its performance cannot be guaranteed.

According to incomplete statistics, more than 80% of the high-speed mixed beds that use this form of water distribution have the problems of unstable effluent water quality and low periodic water production.
