Abstract

The invention discloses a crystal feeding device of a crystallization granulation fluidized bed. The crystal feeding device comprises a seed crystal feeding hopper, a mixed feeding tank, a fluidized bed reactor and a fluidized bed reactor water inlet pump. An outlet of the seed crystal feeding hopper communicates with an inlet of the mixed feeding tank, a top outlet of the mixed feeding tank communicates with an inlet in the side face of the top of the fluidized bed reactor, an outlet of the fluidized bed reactor water inlet pump is divided into two paths, one path communicates with an inlet in the bottom of the mixed feeding tank, and the other path communicates with an opening in the bottom of the mixed feeding tank. The device can solve the problems of large occupied area and high energy consumption of a seed crystal feeding system.

Description

technical field [0001] The invention belongs to the field of high hardness water treatment and relates to a crystal dosing device for a crystallization granulation fluidized bed. Background technique [0002] To remove Ca from wastewater 2+ , Mg 2+ , Fe 2+ , Mn 2+ 、As 3+ , F - Plasma adopts a crystallization granulation fluidized bed process, adding seed crystals to the fluidized bed to complete the reaction to achieve the treatment effect. The height of the fluidized bed is high, and it is difficult to control the operation of adding seed crystals. [0003] The prior art discloses a fully automatic control crystallization granulation fluidized bed seed dosing device, including a seed storage tank, a seed dosing pump, a conveyor belt, a solid mixing and dosing tank, a seed dosing bucket, etc. , but it has the problems of large footprint and high energy consumption. Contents of the invention [0004] The purpose of the present invention is to overcome the above-ment...
