Embodiment

[0039] This embodiment is a specific spouted bed, such as figure 1 In the spouted bed reactor shown, a rotating and controllable deflector 1 is set on the spouted bed bed 3, and the control is realized by the speed-regulating motor 4 on the base of the spouted bed. A series of longitudinal vortex generators distributed in pairs, the diameter D of the longitudinal vortex generator sphere 2 is 4mm, and the diameter of the particles is d p is 0.46mm.

[0040] The sphere is bisected by the deflector, and the horizontal center distance of the pair of longitudinal vortex generators on the deflector is 1.5 times the diameter D of the metal ball, and the longitudinal center distance is 3 times the diameter D of the ball.

[0041] The width of the deflector is L is 20mm, D i 14.3mm, the top of the deflector is located in the area below the spouted bed fountain area to ensure that the structure of the deflector does not affect the overall spouting effect of the spouted bed.

Abstract

The invention discloses a deflector and a spouted bed. The disclosed deflector includes a deflector, and the two surfaces of the deflector are provided with a plurality of protrusions, and the outer surface of each protrusion is sphere. Further, the deflector is a rotatable structure, and the direction of rotation is tangent to the direction of fluid flow. The disclosed spouted bed is equipped with the above-mentioned deflector, and the deflector is located below the fountain area. The invention is simple in structure and easy to process and manufacture, and can effectively overcome the shortcomings of lack of lateral mixing of particles in the traditional spouted bed bed, so that the surface of some particles cannot be fully utilized, and enhance the radial spray area and annular gap area in the spouted bed The horizontal mixing of particles and fluid in the spouted bed improves the overall mass transfer and heat transfer of the particles-fluid in the spouted bed, and increases the overall material handling capacity of the spouted bed.

Description

technical field [0001] The invention relates to a spouted bed reactor used in industries such as chemical industry, environmental protection, energy, metallurgy, etc., in particular to a flow deflector and related spouted beds. Background technique [0002] As a high-efficiency gas-solid contactor, the spouted bed has been widely used in various unit operations and unit processes, such as drying, crushing and granulation of high-viscosity particles, coarse lump particles, slurry and Combustion and gasification, coal-fired flue gas desulfurization, waste incineration flue gas desulfurization, dehydrochlorination gas, carbon dioxide removal, etc. [0003] After more than 50 years of development, spouted beds have come in many forms, among which the most widely used and typical spouted bed is column-cone spouted bed, which has an obvious three-zone flow structure: dilute phase spray zone, dense phase spouted bed Phase ring gap area and fountain area. The particles in the inje...
