Problems solved by technology

The fluidized bed is rarely used in the laboratory, which is mainly because the amount of solid-phase reactants provided in the laboratory is relatively small. Using the fluidized bed treatment method will blow away most of the solid-phase reactants, and the final sample will be Rarely, if not impossible to test samples

example 1

[0034] Example 1, reference figure 1 , 2 , 3, 4, 5, 6, 7, 8, 9. The gas-solid phase reactor consists of a reaction vessel and a rotating body 1, impeller 2, blade 3, inlet pipe 4, exhaust pipe 5, etc. installed therein. The outer body of the reaction vessel is cylindrical and is made of upper, middle and lower parts. The upper body 14 is equipped with an air intake pipe 4 and an exhaust pipe 5, and an air valve 6 is installed on the exhaust pipe 5, which can be used to control the gas flow rate in the exhaust pipe 5, and then change the pressure and reaction gas concentration in the reaction vessel. In addition, the lower part of the upper body 14 is made with an upper external thread 16; the upper end of the middle body 10 is made with an upper inner thread 13, the lower end is made with a lower inner thread 12, and the center of the middle body 10 is made with a central round hole 11. The upper end of the lower body 8 is made with a lower external thread 9 .

Embodiment 2

[0040] Embodiment two, refer to figure 2 , 3 , 4, 5, 6, 7, 8, 10, 11. The difference from Embodiment 1 is that the rotating body 1 is replaced by the elastic clip rotating body 23; and the elastic clip rotating body 23 is made into a shape with front, rear and lower openings, and baffles 25 are connected to both ends of the upper top plate; the elastic clip 24, Make arc-shaped sheet with sheet material, upper edge is fixed on elastic folder rotary body 23 top plate lower surfaces, is positioned at two baffle plates 25, respectively fixes a piece of elastic folder 24 in front and back opening position. The hollow cylindrical structure of the rotary body is the same as that of Example 1, and the structure and working method of the outer body of the reactor are the same as those of Example 1.

Embodiment 3

[0041] Embodiment three, refer to figure 2 , 3 , 4, 5, 6, 7, 8, 10, 12. The difference from the second embodiment is that the rotating body 1 is replaced by an elastic clip rotating body 23 composed of a plurality of strip-shaped elastic clips 26 . Wherein the elastic clip constituting the elastic clip rotating body 23 is formed by fixing more than 2 strip arc-shaped sheets on the lower surface of the top plate of the elastic rotating body 23. The body composition is the same as Example 1, and the operation mode is the same as Example 1 and Example 2.

Abstract

The invention discloses a gas-solid phase reactor with a simple structure and high reaction efficiency. The gas-solid phase reactor consists of an outer reaction vessel body, a rotary body, an impeller and a blade. The rotary body, the impeller and the blade are arranged in the inner cavity of the outer reaction vessel body; the outer reaction vessel body is cylindrical, and an upper body, a middle body and a lower body of the outer reaction vessel body are connected integrally through threads; the impeller is arranged above an interlayer of the middle body; the rotary body is arranged in the inner cavity of the lower body in a suspended mode; the lower part of a wheel shaft of the impeller is manufactured to be a threaded joint; an inner pin hole is formed radially at the threaded joint; a hollow circular cylinder is fixedly connected in the symmetrical center of the upper surface of the rotary body; the upper part of the inner cavity of the hollow cylinder is made to be a screw sleeve; a pin hole is formed radially in the middle of the screw sleeve; the threaded joint of the impeller passes through a middle round hole in the center of the interlayer of the middle body and is screwed with the rotary body through the screw sleeve; and a positioning pin passes through the pin hole and the inner pin hole so that the relative position of the impeller and the rotary body is fixed. Because reactant gas stays in the reactor for a long time, the utilization rate of the gas is high and much solid powder participates in the reaction.

Description

technical field [0001] The invention relates to a gas-solid phase reactor suitable for gas-solid phase material reaction with simple structure and high reaction efficiency. Background technique [0002] At present, it is difficult to find laboratory gas-solid phase reactors on the market. In some literatures, when a gas-solid phase reaction is required, the gas is directly blown to the solid-phase reactant without stirring the solid-phase reactant, so that the reaction efficiency is very low and the reaction is very uneven. For example, some documents using ozone as an oxidizing agent and nickel hydroxide as a reducing agent to prepare nickel oxyhydroxide. The gas-solid phase reactor used in the industry is mainly a fluidized bed, which requires a large amount of gas and a high flow rate, and uses some relatively cheap gases. For example, the roasting of pyrite uses air. The fluidized bed equipment is huge and is mainly used in industrial production. The fluidized bed is ...
