Description
Technical field
The present invention relates to the technical field of garbage incinerating tail gas structure, be 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 invention 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.
