Embodiment 1

[0024] Embodiment 1: A traveling wave microwave reactor includes a reaction device 1, a transmission device 2, a feeding device, and a supporting device. It is characterized in that the reaction device 1 is composed of a cylindrical metal cavity 11 and an anti-leakage device. One end of the metal cavity is provided with a feed opening, and the other end is provided with a corresponding discharge opening. The metal cavity is located on the longitudinal axis of the cross section. Each side is opened with a narrow slit 112 that runs through the whole along the axis, the slit runs through the feeding port, the side wall of the metal cavity, and the discharging port, and the slit width is not more than 20mm. A feeding round hole is opened at the top or bottom end of the longitudinal axis of the cross section of the cylindrical metal cavity 11 at an appropriate position; The conveyor belt 21 passes through the slit 112 and is supported by the support roller 22; the absorbing materia...

Embodiment 2

[0031] Example 2: On the basis of Example 1, the length of the cylindrical metal cavity 11 was changed to 2 m, the center of the coupling ring 31 in the feeding device was 1 m away from the end face of the cylindrical metal cavity 11, and the radius of the coupling ring 31 was Adjusted to 90.89mm.

Embodiment 3

[0032] Example 3: On the basis of Example 1, the cut-off waveguide was replaced with a C14-type standard circular waveguide with an inner surface radius of 78.50 mm. The center of the circular waveguide coincides with the center of the cylindrical metal cavity 11 , and two symmetrical slits are made on the sidewall of the circular waveguide at the position corresponding to the cylindrical metal cavity 11 so that the conveyor belt 21 can pass through the middle. This example makes it possible to process articles with a square cross-section (or other cross-section) with a side length of 50-90 mm, which greatly expands the application range of the reactor.

Abstract

The invention discloses a continuous transmission type circular waveguide microwave reactor, which belongs to the field of microwave energy application devices, and in particular relates to a continuous transmission type circular waveguide microwave reactor. The reaction chamber of the reactor is a cylindrical metal chamber. The metal chamber is divided into two parts along the axial direction for the installation of the conveyor belt. The conveyor belt is installed between the two parts and driven along the axial direction; Outside the body, microwave interference to the inside of the cavity is avoided; a coupling ring is arranged on the top or bottom of the cavity to achieve the purpose of the invention. Therefore, it has the effects of high reaction efficiency, fast speed, high reaction uniformity and energy saving, and it is combined with a continuous transmission production line and applied to large-scale industrial production.

Description

technical field [0001] The invention belongs to the field of microwave energy application devices, in particular to a continuous transmission type circular waveguide microwave reactor. Background technique [0002] At present, high-power microwaves have been widely used in heating, medical treatment, drying, coating, environmental protection, auxiliary extraction and other occasions, and have achieved good results. Now, the application of microwave energy has entered the stage of large-scale industrialization, and the single-treatment box-type microwave reactor is no longer suitable for the needs of industrial production. However, the existing continuous transmission microwave reactor has disadvantages such as low efficiency, uneven field distribution and slow reaction speed. This requires an efficient, uniform and fast continuous reactor to be combined with the existing production line to achieve the purpose of reducing energy consumption, improving efficiency and ensuring...
