Constant-flow water distribution device of mixed ion exchanger

Abstract

The invention discloses a constant-flow water distribution device of a mixed ion exchanger. The constant-flow water distribution device comprises a high-speed mixed bed, an alloy water distribution plate connecting frame and a plurality of constant-flow water caps, wherein the bottom of the high-speed mixed bed is fixed on the alloy water distribution plate connecting frame; a plurality of preformed holes are formed in the alloy water distribution plate connecting frame; one preformed hole corresponds to one constant-flow water cap; each constant-flow water cap comprises a flow equalizing water inlet chamber, a constant-flow valve liner chamber and a water distribution cap which are sequentially communicated from top to bottom; the top of the flow equalizing water inlet chamber is closed;the bottom of the water distribution cap is closed; a plurality of water inlet flow channels are formed in the side wall of the flow equalizing water inlet chamber, a plurality of opening gaps are formed in the side face of the water distribution caps, the size of the opening gaps is larger than the diameter of mixed ion resin in the high-speed mixed bed, and the constant-flow valve liner chamberis fixed in the preformed holes. The device can effectively solve the problem of resin bias flow in the mixed bed body.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering and relates to a balanced flow water distribution device for a mixed ion exchanger. Background technique [0002] In the condensate polishing system, the operation mode of the high-speed mixed bed is to filter and demineralize from top to bottom. The condensate pump disperses the condensed water from the top water distribution plate into the high-speed mixed bed. The lipid layer removes ions in the water to achieve the purpose of desalination and water purification. In the prior art, the top water distribution plate cannot evenly distribute the condensate pump through the water cap connected to the water distribution plate. The property is very strong, and the bias flow phenomenon of the resin in the mixed bed often occurs. When the bias flow is serious, it will cause a significant reduction in the water production cycle of the mixed bed, an increase in the number of regenerations...

In the prior art, the top water distribution plate cannot evenly distribute the condensate pump through the water cap connected to the water distribution plate. The property is very strong, and the bias flow phenomenon of the resin in the mixed bed often occurs

When the bias flow is serious, it will cause a significant reduction in the water production cycle of the mixed bed, an increase in the number of regenerations, an increase in acid and alkali consumption, an increase in wastewater discharge, and an increase in the consumption of desalinated water, which will increase the operating and maintenance burden of operators and affect The economy of the unit and the effect of energy saving and environmental protection
