Description
Technical field
Giving up the spray gun of tar for burning ammonium sulfate device, belonging to the useless tar spray gun field of acrylonitrile incinerator appts, being specifically related to a kind of for carrying sulphur ammonium to give up the tar spray gun of tar and steam.
Background technology
Propylene, ammonia oxidation produce acrylonitrile time, go out rare ammonium sulfate solution of concentration about 21% at quench tower epimere by-product, in rare ammonium sulfate solution containing have an appointment 2% the polymer formed by polymerization such as acrylonitrile, hydrogen cyanide, methacrylaldehyde.Acrylic nitrile waste water incinerator is the supporting environmental protection facility of acrylonitrile installation, incinerator produces a hot environment by combustion of natural gas, make the material generation oxidation reactions such as the cyanide in sulphur ammonium tar, polymer, sulphur ammonium, be decomposed into the material that is nontoxic or low toxicity such as nitrogen oxide, water, carbon dioxide, sulfur dioxide emptying with flue gas height point.Burning method process sulphur ammonium tar is way more thoroughly, solves a difficult problem for process sulphur ammonium tar, and adopt spray gun or injector to be introduced by sulfur waste ammonium tar to carry out burning in incinerator be simple way.When the common fuel oil spray gun of acrylic nitrile waste water incinerator original adoption sprays into, because sulfur waste ammonium tar viscosity is very large, easy condensation, and common fuel oil spray gun only has one-level steam to accelerate, frequent blocking spray gun, simultaneously because fed distance is comparatively far away, tar pump pressure is fallen greatly, often causes the problems such as tar atomization situation is poor, incomplete combustion, incinerator energy consumption are high.Application number be 201020158364.X, 201020158352.7 and 201020158334.9 Chinese patent, though middle delivery pipe body is also divided into two-stage to accelerate sections of atomization, but steam inlet is only provided with one, and steam enters and directly enters accelerating sections afterwards, there is no the time mixed, accordingly, mix incomplete steam and fuel oil, atomization is also incomplete, not only the same easily blockage phenomenon of spray gun, and cause tar to be atomized situation is poor, incomplete combustion and incinerator energy consumption high.
Moreover the Chinese patent " a kind of pair of medium atomization spray gun " of the Chinese patent " band improves the spray gun of spraying " that application number is the Chinese patent " mixture spray gun device " of CN02240083, application number is CN03153671, application number to be the Chinese patent " band improves pre-atomized fluid chemical field and broken spray gun " of CN03153672 and application number be CN201020602873, in addition, application number is also had to be the United States Patent (USP) " Spraygun(spray gun) " of US4202497, these patents above-mentioned such as the United States Patent (USP) of application number to be the United States Patent (USP) " Spraygunwithimprovedatomization(improve atomizing lance) " of US7762476 and application number be US3992976 " Liquidpropellantgun(liquid propellant rifle) " are all the injection apparatus of two kinds of liquid or gas-liquid mixed, for needing in the operation of material Homogeneous phase mixing or spraying, though respective structure is different, but the principle adopted is identical, and all can not be applied in the burning situation of the high heat of high temperature.
Application number is the Chinese patent " a kind of burning spray gun " of CN200520034519, application number is the Chinese patent " a kind of natural gas spraying gun " of CN200820192435, the injection apparatus of to be the above-mentioned patents such as the Chinese patent " the right gas spray gun of a kind of kiln " of CN02276534.4 be all two kinds of gases or gas-liquid mixed that application number is the Chinese patent " multifunctional combined atomizing spray " of CN200910035433 and application number, be generally used for Homogeneous phase mixing, spray burning medium, though respective structure is different, but the principle adopted is identical, it is very large that its structure is equally all not suitable for burning viscosity, the burnt oily matter of easy condensation.
