Description

Technical Field

[0001] This utility model relates to the field of chemical reaction equipment, and in particular to a solid continuous feed synthesis oscillating reactor. Background Technology

[0002] A solid-feed continuous-feed synthesis oscillating reactor is a reactor that combines solid continuous feeding, synthesis reaction, and oscillation enhancement. Its design aims to improve the efficiency and product selectivity of solid-participating synthesis reactions by optimizing mass transfer, heat transfer efficiency, and reaction kinetics. Existing equipment of this type has the following drawbacks: 1. Limitations of batch feeding: Solid materials need to be added intermittently, resulting in large concentration fluctuations (above ±15%) and decreased reaction selectivity.

[0003] 2. Mixed reaction coupling: High-shear mixing and mild reaction conditions cannot coexist in the same cavity, and excessive local shear leads to particle breakage (breakage rate > 8%).

[0004] 3. Uncontrolled solid carryover: Solids are difficult to retain in the equal-diameter reaction chamber, resulting in severe product entrainment losses (carryover amount > 20 q / L). Utility Model Content

[0005] The purpose of this invention is to provide a solid continuous feed synthesis oscillating reactor to solve the problems existing in the prior art. It allows solid particulate materials to continuously enter the solid continuous feed synthesis oscillating reactor, and separates the surface activation of the solid particulate materials from the reaction, avoiding excessive crushing of the solid particulate materials, and retaining the reaction products in the solid continuous feed synthesis oscillating reactor.

[0006] To achieve the above objectives, this utility model provides the following solution: This invention provides a solid continuous feed synthesis oscillating reactor, comprising a continuous feed system, a mixing section, and a reaction section. The discharge end of the continuous feed system is connected to the feed end of the mixing section via a pipeline, and the discharge end of the mixing section is connected to the feed end of the reaction section via a pipeline. The discharge end of the reaction section is equipped with a self-cleaning filter for intercepting solid reactants. The mixing section includes a straight tubular turbulence chamber, a mixing section body for setting outside the turbulence chamber, and a mixing oscillator for driving the oscillation of the mixing section. The first end of the turbulence chamber is the feed end of the mixing section, and the second end of the turbulence chamber is the mixing section. The discharge end of the turbulent cavity is connected to a liquid phase nozzle at its first end; the reaction section includes a straight tubular stabilizing cavity, a reaction section body for setting the stabilizing cavity, and a reaction oscillator for driving the reaction section to oscillate. The first end of the stabilizing cavity is the feed end of the reaction section, and the second end of the stabilizing cavity is the discharge end of the reaction section; the inner diameter D of the turbulent cavity is smaller than the inner diameter d of the stabilizing cavity; the maximum value of the oscillation frequency F of the mixing oscillator is not greater than the minimum value of the oscillation frequency f of the reaction oscillator, and the maximum value of the amplitude A of the mixing oscillator is not greater than the minimum value of the amplitude a of the reaction oscillator.

[0007] In one embodiment, the continuous feeding system includes a feed hopper, a pusher device, and a plate valve. The discharge end of the feed hopper is connected to one interface of the plate valve, and the feed end of the pusher device is connected to the other interface of the plate valve. The feed hopper is located directly above the plate valve, and the discharge end of the pusher device is the discharge end of the continuous feeding system. The system also includes a controller for controlling the opening and closing of the plate valve.

[0008] In one embodiment, the feed hopper is a loss-in-weight metering hopper, and the pushing device is a screw propeller.

[0009] In one embodiment, the controller is an electric motor.

[0010] In one embodiment, the inner diameter D of the turbulent cavity is 0.5d to 0.7d.

[0011] In one embodiment, the oscillation frequency F of the hybrid oscillator is 20 Hz to 50 Hz, and the oscillation frequency f of the reactive oscillator is 10 Hz to 20 Hz.

[0012] In one embodiment, the amplitude A of the hybrid oscillator is 5 mm to 10 mm, and the amplitude a of the reactive oscillator is 2 mm to 5 mm.

[0013] In one embodiment, a valve is provided on the pipeline between the discharge end of the mixing section and the feed end of the reaction section.

[0014] In one embodiment, the continuous feeding system, mixing section, and reaction section are mounted on a frame.

[0015] In one embodiment, the frame is further provided with a solid material pumping system, a liquid material pumping system, and a power supply device, and the liquid phase nozzle is the discharge end of the liquid material pumping system.

[0016] The present invention achieves the following technical advantages over the prior art: This invention provides a solid continuous-feed synthesis oscillating reactor, employing a continuous feeding system to control the material entry, ensuring uninterrupted feeding while stabilizing the material flow at a suitable velocity. Solid particulate materials reach a surface-activated state through collision in the mixing section, and then undergo material reaction in the reaction section; surface activation and material reaction occur separately. The turbulent chamber in the mixing section has a small inner diameter, high oscillation frequency, and large amplitude, resulting in a high flow velocity of the solid particulate materials and a large turbulent velocity in the mixture with the liquid material, which can more quickly activate the surface activity of the solid particulate materials participating in the reaction. The steady-flow chamber in the reaction section has a large inner diameter, low oscillation frequency, and small amplitude, resulting in a slower flow velocity of the solid particulate materials and a longer reaction time. A self-cleaning filter can retain solid products in the final product, avoiding product loss. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 and Figure 2 As shown, this utility model provides a solid continuous feed synthesis oscillating reactor, including a continuous feed system 1, a mixing section 2, and a reaction section 3. The discharge end of the continuous feed system 1 is connected to the feed end of the mixing section 2 via a pipeline, and the discharge end of the mixing section 2 is connected to the feed end of the reaction section 3 via a pipeline.

The inner diameter D of the turbulent flow cavity 201 is smaller than the inner diameter d of the flow stabilizing cavity 301. The maximum value of the oscillation frequency F of the mixing oscillator is not greater than the minimum value of the oscillation frequency f of the reaction oscillator, and the maximum value of the amplitude A of the mixing oscillator is not greater than the minimum value of the amplitude a of the reaction oscillator.

[0026] In one implementation, the self-cleaning filter is a PTFE membrane.

[0027] In one embodiment, the continuous feeding system 1 includes a feed hopper 101, a pusher device 102, and a plate valve 103.

Activating the pusher device 102 continuously feeds the solid particle raw materials from the feed hopper 101 into the mixing section 2.

The valve 4 can directly cut off the connection between the mixing section 2 and the reaction section 3, avoiding interference between the surface activation process and the reaction process.
