Embodiment 1

[0073] Utilize the gasification and cracking device based on microwave heating in the present invention to gasify and produce sulfur gas, the process is as follows:

[0074] Such as image 3 , Figure 4 As shown, in this embodiment, solid sulfur is used as a raw material, which is indirectly heated and melted into liquid sulfur by a steam coil, and then sent to a sulfur filter 616 by a crude sulfur pump 617 to filter and remove solid and organic impurities. After filtering, the refined liquid sulfur is put into a refined sulfur storage Store in tank 615, then adjust and control the amount of sulfur through refined sulfur pump 614 and flow meter 613, and send the liquid material inlet 61 of gasification cracking furnace shell 2, directly atomized by atomizing nozzle 611, and pass through gasification cracking furnace shell 2 Microwave heating gasification to obtain high temperature sulfur gas.

[0075] Gasification and cracking furnace shell 2 is made of SS304 stainless steel...

Embodiment 2

[0080] Such as Figure 5 , Figure 6 As shown, in this embodiment, liquid sulfur is used as a raw material, and the molten sulfur tank 618 uses heat conduction oil for indirect heating and heat preservation to maintain the molten liquid sulfur. The atomization of liquid sulfur uses nitrogen to assist blowing and atomization, and the shell 2 of the gasification cracking furnace is made of ordinary carbon steel. , the divider 4 adopts a porous ceramic plate, and the heating carrier 5 adopts an integral block hole silicon carbide absorbing material with a pore diameter of 3-15mm. Sulfur liquid or gas passes through the hole of the silicon carbide block, and the microwave acts on the block to make the whole block When the body temperature rises, the sulfur material contacts the block holes to absorb the heat of the block, and is heated and gasified and cracked. Seven 100kW, 915MHz microwave generation systems 1 are used for the gasification chamber 22, five 100kW, 915MHz microwav...

Embodiment 3

[0085] Such as Figure 7 , Figure 8 As shown, in this embodiment, the gasification and cracking furnace shell 2 is provided with a liner 20 made of ceramic or silicon carbide. Using solid sulfur as the raw material, the solid sulfur particles enter the storage bin 626 for buffering, and after being stabilized by the feeder 625 and weighing equipment 624, they are sent to the screw extruder 623, and the solid sulfur is melted by electric heating on the screw shell It is liquid sulfur, squeezed into the connecting pipe assembly 622, and then distributed to the lower liquid distributor 621. The liquid distributor 621 adopts the liquid distribution pipe type, which is composed of multiple concentric rings and communicates with the connecting pipe assembly 622. The bottom of the liquid distributor 621 is evenly distributed with 1-6mm liquid spray holes, relying on the screw extruder The 623 extrusion pressure sends the molten liquid sulfur into the gasification cracking furnace,...

Description

technical field [0001] The invention belongs to the technical field of gasification and cracking, and relates to a microwave heating-based gasification and cracking device and a method for rapidly preparing high-temperature sulfur gas. Background technique [0002] The gasification and cracking furnace is a device used for gasification and cracking reaction of solid or liquid materials. For sulfur, waste sulfuric acid, organic matter, biomass, coal and other materials, the gasification and cracking process needs to be carried out in a high-temperature closed gasification and cracking furnace. [0003] Generally, the process requires the gasification and cracking furnace to quickly heat the reactants to a temperature of 300-1200 ° C or even higher to ensure short residence time of the medium, less side reactions in the process, high product yield, and stability and high efficiency. Heat supply and heat transfer, and economical and applicable high temperature and corrosion re...
