Abstract
The present invention discloses a solid adsorbent-viscous oil fume adsorbent. It is a uniformly-mixed material consisting of 19-38% of sawdust, 25-45% of husk, 14-40% of coke and 3-19% of pulverized cinder. The raw materials of said adsorbent are easily available, and its cost is low, adsorption capability is strong, and its comprehensive purification effect is good, and the comprehensive removing rate of toxic and harmful substances in the viscous oil fume is up to above 96% and the removing rate of 3,4-benzopyrene is up to 99%.
Description
The present invention relates to a kind of solid absorbent, is a kind of viscous oil flue gas adsorbent specifically.
Food cooking processing and some factory all can produce a large amount of viscous oil flue gas as asphalt felt-making factories, pitch factory etc. in the processing process, wherein contain tens kinds even hundreds of poisonous and harmful substance, and majority has carcinogenicity.Use the filtration adsorption plant can purify viscous oil flue gas, but at present lack of materials be easy to get, the adsorbent of low price, good purification, normal active carbon, the aluminium oxide of using substitutes, in this class material many micropores are arranged, it is effective to be used to adsorb noncohesive gas, but then surrounded by stickum easily when being used to purify viscous oil flue gas because of its surface, form diaphragm and reduce its adsorption capacity greatly, therefore adsorption cycle is short, need frequent the replacing, add that material price is expensive, about about 4 yuan as the active carbon per kilogram, cause purification expense height; Active carbon or alumina composition are single in addition, and adsorbable gaseous species is few, so can not remove the multiple harmful components in the viscous oil flue gas effectively.
The purpose of this invention is to provide that a kind of material is easy to get, low price, the effective viscous oil flue gas adsorbent of comprehensive purifying.
The present invention is achieved in that a kind of viscous oil flue gas adsorbent, the homogeneous mixture that it is made up of sawdust, husk, coke and slag, and their proportioning is sawdust 19～38%, husk 25～45%, coke 14～40%, slag 3～19%.
Utilize said components that the adsorption filtration effect of viscous oil flue gas is reached the purification purpose among the present invention, but because the surface area difference of every kind of material, physics, chemical property difference, kind and the quantity that can remove the poisonous and harmful substance in the viscous oil flue gas are also different, wherein sawdust and husk are better to the condensation of hydrocarbons removal effect, coke is then preferable to the gaseous hydrocarbon removal effect, and slag is except that having certain adsorption capacity, and it mainly acts on is the proportion that is used to improve this adsorbent.Compared with prior art, remarkable advantage of the present invention is: material source extensively, obtain easily; Low price, per kilogram are 0.4 yuan, are 1/10 of active carbon; Adsorbance is big, adsorbable 3～3.5 kilograms of viscous oil flue dust of per kilogram viscous oil flue gas adsorbent, and the per kilogram activated carbon to viscous oil flue dust adsorbance less than 2.5 kilograms; The comprehensive purifying ability is strong, and the comprehensive clearance of the poisonous and harmful substance of viscous oil flue gas is reached more than 96%, the 3.4-BaP clearance in the viscous oil flue gas is reached 99%, and active carbon is only applicable to the adsorption cleaning of non-sticky gas.
Now in conjunction with the accompanying drawings and embodiments the present invention is described specifically:
Fig. 1 is for utilizing a kind of viscous oil fume purifier structural representation used in the present invention;
Fig. 2 is the generalized section of Fig. 1.
Provide the embodiment of the concrete prescription of viscous oil flue gas adsorbent provided by the present invention below:
Embodiment sawdust husk coke slag
1 19% 35% 40% 6%
2 29% 25% 27% 19%
3 38% 45% 14% 3%
The viscous oil flue gas adsorbent that makes by above-mentioned prescription is used for the viscous oil fume purifier as filtering absorbing material.As depicted in figs. 1 and 2, this clarifier comprises the shell 4 on support 5 and the support 5, the bottom side of shell 4 is provided with air inlet 1, the top is provided with gas outlet 2, the side is provided with dress discharge port 3, and the bottom is provided with discharge gate 6, and 2 6～10 layers of being provided with horizontal interlaced arrangement filter adsorption layer 2 to the gas outlet from air inlet 1 in the shell 4, it is made up of netted pallet and the viscous oil flue gas adsorbent that evenly is layered on the pallet, and the pallet movable supporting is on screen work set on shell 4 inwalls.Clarifier is installed in the ventilating system and uses, and viscous oil flue gas flows into machinery through the multiple filtration adsorption layer by air inlet 1 and dams and filters suction-operated, remove toxic and harmful and viscosity organic matter wherein after, purified gas is by gas outlet 2 discharges.With after viscous oil flue gas adsorbent can take out from the dress discharge port with pallet and outwell, the pallet that also can overturn falls down, and discharges from discharge gate 6 and makes Solid Waste Treatment, stone uses again on pallet.It is good that this adsorbent filters absorption purifying effect to viscous oil flue gas, and low price, and raw material sources are wide.
