Fluidized reactor used on circumfluent type adsorption tank

The utility model relates to a fluidized reactor used on a circumfluent type adsorption tank and belongs to fitting parts of water treatment equipment. The fluidized reactor comprises a throat pipe section and a lifting section, wherein the upper end of the throat pipe section is in sealing connection with the lower end of the lifting section; the ratio of the cross section area of an outlet of the lifting section to the cross section area of the throat pipe section is 25:4-9:1; the height ratio of the lifting section to the throat pipe section is 3:1-4:1; the ratio of the inner diameter of the biggest part of the lifting section to the inner diameter of the smallest part of the lifting section is 5:2-3:1; a spiral groove is formed in the inner wall of the throat pipe section; the lower end of the throat pipe section is in sealing connection with a mixing chamber; and the upper part of the mixing chamber is of an umbrella structure, the lower part of the mixing chamber is of a cylindrical structure, and the upper umbrella structure is in sealing connection with the lower cylindrical structure. The fluidized reactor can meet working requirements of the circumfluent type adsorption tank to ensure that the circumfluent type adsorption tank does not need a stirrer, is low in energy consumption, can fully mix wastewater and an adsorbent under a certain pressure at a certain speed, is long in adsorption exchange time, good in adsorption effect and good in effect of separating purified water and the adsorbent, and reduces the impact of water on sediments, thereby overcoming the defects in the prior art.
