Description
Technical field
The invention belongs to the applied technical field of microwave in desulfurization, the device that particularly a kind of oil liquefied gas, gasoline desulfur are handled.
Background technology
The composition that all contains sulphur in the middle of existing oil liquefied gas and the gasoline mostly, sulfur method in the past are to adopt chemical process to carry out desulfurization, are called the patent of invention of " ammonia water process to desulfurize liquefied gas " like patent No. ZL00111256, name.
The prior art close with the present invention is that publication number is that CN1103350, name are called the application for a patent for invention of " method for desulfuration regeneration of waste rubber ".Disclose and utilized microwave and infrared heat reservoir, with suitable cooperation, the waste vulcanized rubber powder of interval re-treatment, the method for producing shoddy.But only mention that " making the mixing rubber powder pass through microwave radiation " and microwave dosage are 55～100wh/kg.This patented claim does not provide concrete device, and just through " microwave is set indirectly " and " stirring stirring ", solution is clamminess, is smoldered even the problem of charing.
Summary of the invention
The technical problem that the present invention will solve is a kind of device that adopts the microwave exposure desulfurization of design; Not only realize the desulfurization of oil liquefied gas or gasoline is handled, and can avoid because the fire accident of the inflammable gas that the tiny leakage of microwave source, reaction kettle or pipe laying produces.
Concrete technical scheme of the present invention is following, and Reference numeral can be referring to Fig. 1.
A kind of oil liquefied gas or gasoline desulphurization microwave reaction kettle; Structure comprises microwave source 1, micro-wave coupler 2, the tuner 4 that magnetron and magnetron power source constitute by the microwave conduction sequence; Described tuner 4 is one section rectangular waveguide, and the wavelength of its size and microwave source 1 is complementary; It is characterized in that structure also has transition waceguide 6, ventilation safety shield retaining 7, isolation window 8 and the reaction cavity 9 of rectangular waveguide and circular waveguide; Described transition waceguide 6, its rectangular opening termination tuner 4, the columnar ventilation safety shield retaining 7 of its round mouth termination; Described reaction cavity 9 is the billys that have feeding mouth and discharge port in the side of leaning on two ends respectively, near the cylinder termination sealing of feeding mouth, is tightly connected through isolating window 8 and ventilation safety shield retaining 7 near the cylinder termination of discharge port; Described isolation window 8 is quartz or microwave ceramic material, and both sides add toroidal ring piece shape sealing-ring 3 respectively between ventilation safety shield retaining 7 and reaction cavity 9; Described ventilation safety shield retaining 7 is one section circular waveguide, and ventilation hole is opened in its side.
Ventilation safety shield retaining 7 length of the present invention are preferably 0.3～1m, and the ventilation hole diameter that open its side can be 2～3mm, the perforate total area of ventilation hole account for ventilation safety shield retaining 7 side surface long-pending 20～50%.The too short or ventilation hole on it of ventilation safety shield retaining 7 very little, ventilation can be too little, do not have the effect that forms one section clean air isolated area between microwave source and the reaction cavity 9, still has the fire hidden danger of inflammable gas tiny leakage generation; Ventilation safety shield retaining 7 is oversize or the ventilation hole on it is too big too many, can cause ventilation safety shield retaining 7 this section circular waveguide physical strengths to reduce, and influences its work-ing life.
Consider that from practical application the output rating of described microwave source 1 can be in 0.5～30KW scope; Described reaction cavity 9 length can be at 2～10m, and internal diameter is greater than the microwave cutoff wavelength, and the internal diameter maximum can reach 1.5m; The feeding mouth on the reaction cavity 9 and the internal diameter of discharge port are less than the microwave cutoff wavelength.When the volume of reaction cavity 9 is big, can and open a plurality of feeding mouths and discharge port, the contradiction that limited by the microwave cutoff wavelength with big flow and feeding mouth and the discharge port that solves oil liquefied gas or gasoline.
The present invention has sweetening effectiveness preferably to flammable liquid, and desulfurization degree is more than 95%; The fire hidden danger that can avoid the tiny leakage of inflammable gas to cause.Oil liquefied gas or gasoline that the present invention handles all are inflammable and explosive substances; Therefore between microwave source 1 and reaction cavity 9, increase a ventilation safety shield retaining 7; Its objective is the microwave that sends by microwave source through one section ventilation safety shield retaining 7,, avoid because the tiny leakage of inflammable gas with causing one section clean air isolated area between microwave source and the microwave reaction cavity 9; Since the accidental arcing of the high-strength microwave field at the circuit of microwave source or microwave transmitting antenna place, the fire accident that causes.
