Problems solved by technology

[0006] When the above-mentioned mixer is used for the mixing of liquid and liquid reaction to generate flocculent high-viscosity materials, it is easy to cause the high-viscosity materials to adhere to the gap between the rotor and the stator mixing teeth, and the high-viscosity materials generated by the reaction are due to stickiness. Strong adhesion, difficult to discharge from the mixer

preparation example Construction

[0030] In the method for preparing NaY molecular sieve gel provided by the present invention, aluminum sulfate, water glass and directing agent are metered through respective feeding pipes according to the weight ratio of (1~1.2): (9~11): (4.6~5.5) Introduced into the fluid continuous reactor, the liquid raw material in the mixing chamber 4 is quickly atomized into fine droplets through the feed atomizing nozzle 2, so that several liquids can contact and react instantly in the mixing chamber 4, and the mixing blades in the mixing chamber 4 5. Further, several kinds of atomized liquids are stirred rapidly and mixed into a uniform material; then enter the crushing chamber 8, and undergo the relative motion of the stator teeth and the rotor teeth for grinding and crushing, and crush the blocky materials that may be produced during the reaction. Under the action of centrifugal force, the final reaction material is thrown away from the mixing chamber and enters the blade 12 of the c...

Abstract

The invention discloses a fluid continuous reactor and application thereof. The fluid continuous reactor comprises a cavity consisting of a front shell (3) and a rear shell (14), a feed pipe (1) opened on the front shell and a power input main shaft (6) arranged on the rear shell, wherein the front shell is raised to form a cavity which is a quick mixing chamber (4); the front end of the main shaft extends into the quick mixing chamber (4); the front end of the main shaft (6) is provided with a mixing blade (5); a rotor (7) is arranged on the main shaft on one side of the rear shell in the cavity, the rotor (7) is a round pad consisting of rotor teeth (9) and a centrifugal impeller (12) thereon, the rotor teeth (9) are mutually engaged with stator teeth (10) arranged on the front shell (3), and the clearance of the rotor teeth and the stator teeth forms a pulverizing chamber (8), and the cavity where the centrifugal impeller (12) is positioned is a conveying chamber (11); and an output pipe (13) is tangentially arranged on the outer edge of the shell of the conveying chamber (11) and communicated with the conveying chamber (11). The fluid continuous reactor provided by the invention is suitable for a reaction process of generating high-viscosity colloid product with sediment and floccules by quick reaction of liquid raw materials.

Description

technical field [0001] The present invention relates to a fluid continuous reactor, more specifically, relates to a kind of machine and equipment for rapidly mixing and reacting two or more liquids in an airtight container continuously to form another liquid or colloid. Background technique [0002] In the chemical industry, processes such as mixing and reacting of liquids are often encountered. Most of these processes are slow reactions of heating and pressurization. For this reason, high-pressure reactors are generally used to complete intermittently; some rapid fluid reactions that do not require heating and pressurization are basically completed by batch reactors; or static mixers are used to achieve continuous mixing reactions. Batch reactors are more suitable for some processes with slow reaction speeds that require heating and pressurization, but for some fluid reactions with fast reaction speeds, there are many equipments, small processing capacity, low efficiency, a...
