Description
Technical field
The present invention relates to a kind of decomposing gas device, be specifically related to a kind of ammonia destruction furnace that heats with the combustion gas mode.
Background technology
Present stage, the development of industrial gasses equipment such as ammonia destruction furnace is very fast, has been widely used in being applied to various fields such as petrochemical complex, chemical fibre, thermal treatment, metallurgy, glass, food, medicine, electronics, national defence space flight, aviation.Present comparatively common ammonia destruction furnace; Its structure generally comprises the inner bag casing, be arranged on tracheae on the inner bag casing, be arranged on the intravital flue of inner bag case; At least one tracheae is connected with the top of each flue respectively as inlet pipe; At least one tracheae is connected with the bottom of each flue respectively as escape pipe; Sidepiece at flue is provided with heating unit so that flue is carried out heat, makes to carry out pyrolytic decomposition under the effect of ammonia catalyzer in flue after inlet pipe gets into each flue and form the mixed gas of ammonia and nitrogen, and mixed gas is discharged from escape pipe.The ammonia destruction furnace of this kind structure exists objectively that flue is heated inadequately evenly, unit consumption of energy is high, the body of heater heating unit is prone to aged deterioration, shortcomings such as repair and replacement difficulty.
To the existing some defectives of ammonia destruction furnace in practical application, many entity and individual have proposed some new improvement projects.Applied for the utility application (number of patent application is 200520070818.7) of " ammonia destruction furnace " by name on April 15th, 2005 like Gaopu Ultrapure Gas Technology Co., Ltd., Suzhou; It discloses a kind of ammonia destruction furnace; Comprise the inner bag casing, be arranged at flue in the inner bag cabinets cavity, pass at least two tracheaes on the inner bag casing; The intracavity inter-connection of tracheae and flue is provided with many pipe cores in the inner chamber of described inner bag casing, pipe core is provided with nichrome wire; Have many on the wall of the inner bag casing in the outside, described pipe core two ends to open hole; Described each open hole internal fixing has sleeve pipe, and the both ends of pipe core are inserted in respectively in the described sleeve pipe, has casing cover on the described telescopic outer port part.The advantage of this technical scheme is when nichrome wire burns out, and directly pipe core being taken out from the inner bag casing is replaceable nichrome wire, and it changes process simple and fast, but and fails effectively to solve flue be heated inequality, problem that unit consumption of energy is high.After this, Suzhou is newly thought gas system ltd and has been applied for the utility model patent of " ammonia destruction furnace body " by name, (number of patent application is 201020022228.8) on January 18th, 2010; It discloses a kind of ammonia destruction furnace body; Mainly comprise simplified, the tube end insulating brick, anchor, quarl, magnetic core and nichrome wire, anchor and cylindrical shell weld together, and quarl is stuck on the bayonet socket of anchor; Nichrome wire is wrapped on the magnetic core, and magnetic core is installed on the quarl.The advantage of this technical scheme is to have guaranteed the quarl mounting stability through anchor; Quarl makes nichrome wire easier for installation; Use safer; Anchor makes the installing and locating of nichrome wire more convenient, and more reasonable structure has solved body of heater making location difficulty in the prior art, used problems such as there being potential safety hazard.Suchlike patented technology or proprietary technology also have a lot, but all stick to this mode of resistive heating, fail effectively to overcome flue be heated inequality, deficiency that unit consumption of energy is high again.
Summary of the invention
The technical problem that the present invention will solve is the flue of the existence deficiency inhomogeneous, that unit consumption of energy is high of being heated in overcoming that existing electric resistor heating type atmosphere decomposing furnace is actual and using; A kind of novel ammonia destruction furnace that adopts the combustion gas heating is provided; This gas heating type decomposing furnace can not only make the flue thermally equivalent, and can effectively reduce unit consumption of energy.
The present invention solves the problems of the technologies described above the technical scheme of being taked: a kind of combustion gas adds the heat radiation type ammonia destruction furnace; Comprise body of heater, flue, inlet pipe, fume extractor; Said body of heater inner chamber lower, parallel is provided with heat accumulation plate, and said heat accumulation plate downside is the combustion chamber, and said combustion chamber is connected with the combustion unit that is located at the body of heater both sides; Said flue is positioned at the heat accumulation plate top of body of heater inner chamber, and the said flue outside is provided with the radiative transfer device that can make the flue thermally equivalent.
As further improvement of the present invention, said radiative transfer device is the corrugated spacer, is vertical round barrel shape and is arranged at the flue outside.
Further improve as of the present invention, said corrugated spacer spacer is formed by the bending of SUS310S stainless steel plate.
Advantage of the present invention be combustion gas with direct incendiary mode through combined load-bearing and radiation in the heat accumulation plate of one function with heat to the radiation of ripple spacer; Can guiding gas flow to the combustion chamber heat through unique chamber design simultaneously to the even convection current of ripple spacer; Thereby increase substantially thermo-efficiency and temperature homogeneity; Thereby the gas production rate that has overcome traditional ammonia destruction furnace existence is low, energy consumption is high, safeguards shortcomings such as inconvenience.Wherein the bending of ripple spacer employing SUS310S stainless steel plate is a ripple type, helps to eliminate stress and the distortion at high temperature of ripple spacer; And ripple spacer long service life, reduced investment output ratio.The present invention has broken through traditional thinking restriction; Structure design through science makes the present invention all obtain outstanding success with commercial technically simultaneously; Compare with resistance-type ammonia destruction furnace of the same type, every cube of protection gas energy consumption cost of the present invention is merely 0.7 yuan, than the energy consumption reduction by 36.37% of electrical heating type; The energy-conservation effect effect of falling is very remarkable, has obtained widespread use in a plurality of fields.
