Embodiment
The present embodiment comprises the overall similar coniform shell of a band cooling water jecket, and the cylinder that this coniform shell is reduced successively by three diameters welds together, and there is multiple cylindric cavernous body inside, and cavernous body is fixed by the sheet iron with circular hole.Shell three cylinders of this device divide three grades, and most subordinate is maximum, and between the inner cavernous body of chuck, space is maximum; Space, the second level reduces half, and third level cavernous body is adjacent, and inside is filled with cavernous body.During work, cavernous body is full of washing oil, and flue gas enters jacketed cooler 1 along cooler passage 6, and in cooler, the cooling water of flowing carries out one-level cooling to bitumen flue gas, and temperature is reduced to 80-100 DEG C from being greater than 150 DEG C; Flue gas enters in one-level suction filter 2 afterwards, has the washing oil in the cylindrical silicon gelatin sponge body 8 of hollow to absorb bitumen flue gas, the Main Ingredients and Appearance mainly in bitumen flue gas: fused aromatic compounds, resinite, oil content are dissolved in washing lotion in suction filter.Nubbin flue gas enters secondary suction filter 3, and the washing oil while cooling in hollow silica-gel sponge body 8 absorbs flue gas and is dissolved in washing lotion.The flue gas of residue minute quantity enters in three grades of suction filters 4, and have washing lotion in the NBR sponge rubber body of inner circular columnar hollow, Main Ingredients and Appearance is suds, the phenyl ring in flue gas, anthracene, phenanthrene, pyrene composition can be adsorbed, namely be dissolved in suds.Now temperature is down to less than 70-40 DEG C, and most bitumen flue gas is absorbed by washing oil and washing lotion, but still has minute quantity foreign gas to enter in adsorbent bed 5 to be absorbed by petroleum coke powder after activated carbon or forging.By level Four adsorption filtration, its flue gas adsorption cleaning rate can reach more than 99%.Reach discharging standards.
Containing adsorption in bitumen flue gas, benzene type organic, small part straight-chain hydrocarbons and water vapour, wherein containing 3,4-BaP etc. is carcinogen; These compositions are included in pitch, and the softening point of mid temperature pitch is generally 65-90 degree, and more than 90 degree form bitumen flue gas.The multiplex carbon coated graphite of lithium ion battery negative material, the coated level adopted mostly is mesophase spherule precursor of high-purity pitch, carbide furnace temperature is that 20-1200 degree can produce a certain amount of bitumen flue gas, the oven door opening when push pedal advances material and discharging, and flue gas ejection stove gate upwards wafts.Therefore fix a large range hood above stove gate, shape is taper, and lower opening enters flue gas, and the thin mouth in top places apparatus of the present invention.The high-temperature gas of more than 150 degree upwards flows and is introduced in petticoat pipe, upwards run and enter again in water cooler, now temperature can be reduced to less than 70 degree, after cooling, enter flue gas absorbing devices, through three-stage filtration absorption, most pernicious gas can be absorbed, now temperature can be reduced to less than 30 degree, the flue gas Yin Wendu of last minute quantity is reduced in below softening point, becomes liquid become solid again by gas, and rapid condensation is attached to cavernous body surface or is absorbed by washing oil! After such adsorption filtration, total treatment effeciency can reach more than 99%, can reach environmental protection standard.
