Description
Technical field
The utility model relates to the technical field of garbage incinerating tail gas structure, is specially a kind of active carbon injection apparatus.
Background technology
Dioxin refers to the chlorine-containing organic compounds linking 2 phenyl ring containing 2 or 1 oxygen key, its english name " Dioxin ".Because Cl atom is different at the position of substitution of 1 ~ 9, form 75 kinds of isomers many chloros hexichol (PCDD) and 135 kinds of isomers polychlorinated dibenzos (PCDF), usually dioxin is generically and collectively referred to as, its molecular weight 321.96, for white crystals body, m. p.: 302 ~ 305 DEG C, 500 DEG C start to decompose, and when 800 DEG C, 21s decomposes completely.Wherein have 17 kinds (2,3,7,8 are replaced by Cl) be considered to the mankind and biohazard the most serious.Dioxin stable in properties, the half-life in soil is 12a, and the half-life of gaseous state dioxin photochemical breakdown is in atmosphere 8.3d, slow at people's vivo degradation, is mainly accumulated in adipose tissue.Dioxin is a kind of strong toxic organic material containing Cl, exists hardly, only have and could be produced by chemical synthesis at occurring in nature, is the most fearful chemical substance that the current mankind create, is called as " poisonous substance that on the earth, toxicity is the strongest ".
The burning of municipal refuse, industrial chemical waste, motor vehicle fuel oil and home-use coal and cigarette all can produce a small amount of dioxin, and the dioxin wherein emitted by waste incineration accounts for 80% ~ 90% of dioxin total release; The burning of domestic waste is the main source of dioxin, therefore, reduces the generation of dioxin early stage by controlling waste incineration, and the later stage adopts the method for physics and chemistry to adsorb dioxin, reaches the discharge controlling dioxin to greatest extent; Method both economical at present adopts charcoal absorption dioxin, in order to reduce the total emission volumn of dioxin fully, improve the absorptivity of dioxin, what active needs were full and uniform is diffused in flue gas, improve the chance that dioxin contacts with active carbon, make it fully be adsorbed, because of the flow velocity of flue gas and the diffusivity of deduster air intake flue limited.
Existing active carbon injection apparatus, is shown in Fig. 1, and adopt straight tube to be directly inserted in flue, the spout of injection apparatus adopts straight spout, and the diffusion effect of straight spout is not so good, so can not all the covering on flue circulating face of the active carbon ejected.In figure A be injected to the active carbon diffusion region of flue, B is the active region do not covered, because the diffusion angle of straight spout is little, it is not high to spray flow velocity, the centre position concentration of the diffusion region of spraying is higher, fringe region concentration is low, active carbon diffusion stroke L is not enough to make active carbon cover whole circulating faces of flue gas throughput direction, dioxin in flue gas can not fully be contacted with active carbon, dioxin absorbed power is low, easily makes dioxin enter in extraneous air, welding.
Summary of the invention
For the problems referred to above; the utility model provides a kind of active carbon injection apparatus; it makes the active carbon in flue can cover whole circulating faces of flue gas conveying; and the even concentration of the diffusion region of active carbon; guarantee that the dioxin in flue gas fully contacts with active carbon; make the absorbed power of dioxin high, make dioxin not easily enter extraneous air, protection external environment condition.
A kind of active carbon injection apparatus, its technical scheme is such: it comprises flue, in described flue, circulation has flue gas, active carbon injection pipe is furnished with in described flue, described flue gas is vented from front to back along described flue, it is characterized in that: described active carbon injection pipe comprises the charging aperture exposing to described pipeline upper end, the connecting pipe of Vertical dimension, horizontal direction outlet conduit, the outlet of described horizontal direction outlet conduit is the horn-like of outside enlarging, the entrance of described horizontal direction outlet conduit connects the lower part outlet of the connecting pipe of described Vertical dimension, described level is arranged to outlet conduit along the outgassing direction of flue gas, described level is furnished with speedup cone to the center of the outlet of outlet conduit, the fore-end of described speedup cone is pyramidal structure, described pyramidal structure is the taper of enlarging from front to back.
It is further characterized in that: the rear end part of described speedup cone is the pyramidal structure closed up from front to back, and the central region of described speedup cone is sectional area largest portion;
The outer face of trumpet-shaped described outlet is furnished with the connecting plate of strip, and all described connecting plates are towards center arrangement, and the central region that described speedup is bored is flush-mounted in the center-mount location that all connecting plates combine;
Preferably, described connecting plate is specially four pieces, four pieces of described connecting plates are distributed in the outer face of described outlet, and the inner of described connecting plate is respectively towards center arrangement, and the central region of described speedup cone is flush-mounted in center, the corner mount pad that all connecting plates combine.
After adopting structure of the present utility model, active carbon powder enters into charging aperture along conveying air, then through the connecting pipe of Vertical dimension, horizontal direction outlet conduit enters in flue eventually through trumpet-shaped outlet, center due to outlet is furnished with speedup cone, the fore-end of described speedup cone is pyramidal structure, described pyramidal structure is the taper of enlarging from front to back, wherein speedup is bored the circulation area that the outlet of horizontal direction outlet conduit is sprayed and is diminished, the fluid pressure being positioned at speedup cone front end improves, fluid velocity improves, speedup cone is flow direction property structure simultaneously, the fore-end of speedup cone progressively increases pressure and the speed of fluid, and resistance is little, and owing to exporting as flared structure, it guarantees that active carbon enters into flue in diffusion type fast, and due to speedup cone blocked center parallel current pass through, the generation eddy current in this region can be avoided, reduce the resistance after fluid ejection, outlet position pressure loss in speedup process of whole nozzle is less, substantially increase the effect of speedup, it allows active carbon powder from the ejection of outlet surrounding, reduce the active carbon spray volume in the middle of nozzle, increase the diffusingsurface of active carbon in same distance, make the active carbon in flue can cover whole circulating faces of flue gas conveying, and the even concentration of the diffusion region of active carbon, guarantee that the dioxin in flue gas fully contacts with active carbon, make the absorbed power of dioxin high, dioxin is made not easily to enter extraneous air, protection external environment condition.
