Accompanying drawing explanation
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
With reference to Fig. 1, this specific embodiment is by the following technical solutions: mica tape goods toluene waste gas retracting device, comprise exhaust fan 1, urgent triple valve 2, preprocessor 3, drying air fan 4, A absorber 5, B absorber 6, positive displacement pump 7, toluene storage tank 8, layering groove 9, spiral plate condenser 10, cyclone separator 11, shell and tube condenser 12 and hydrotreater 13, containing toluene waste gas by exhaust piping respectively with urgent triple valve 2, preprocessor 3, exhaust fan 1 is connected successively, A absorber 5, B absorber 6 is all connected with saturated steam, drying air fan 4 drying airducts respectively with A absorber 5, B absorber 6 is connected, A absorber 5, B absorber 6 is respectively by materail tube and shell and tube condenser 12, cyclone separator 11, layering groove 9, toluene storage tank 8 is connected, shell and tube condenser 12 is connected with cooling water intake and water return outlet, positive displacement pump 7 is connected with toluene storage tank 8, layering groove 9 is connected with cooling tower by hydrotreater 13.
Each parts of this specific embodiment are connected with connecting line valve member by pipe valve.Toluene waste gas after centralized collection is under the driving of exhaust fan high pressure; first carry out pretreatment dust removal and filtration, show the pretreatment such as cold cooling and high boiling substance separation, waste gas pretreatment object is to protect adsorption bed, improves the adsorbent life-span, guarantees that efficient adsorption purifies.Pretreated organic exhaust gas directly enters carbon fiber adsorption and catalytic combustion device A and adsorbs.(at a threeway emergency blow-down valve being connected with system of fan outlet design, so as equipment break down and when overhaul of the equipments as the direct floss hole of organic exhaust gas, can not affect the continuous production in workshop, upstream.When system is normally worked, waste gas is entered in absorber and is adsorbed by switch valve).Organic exhaust gas enters carbon fiber adsorption and catalytic combustion device and adsorbs, and in waste gas, organic solvent is held back by the micro-porous adsorption of NACF, and the gas after adsorption cleaning can obtain very high discharge cleanliness factor.Absorption organic solvent reaches capacity or approaches saturated NACF, carries out desorb with saturated steam.High temperature saturated steam can be provided by the adsorbent bed larger heat that provides, and make the vehicle substance being adsorbed obtain energy, improve kinetic energy, increase vapour pressure, thereby the constraint in disengaging duct desorbs.The organic solvent desorbing and the mixture of steam enter pipe bundle condenser, condensed gas-liquid mixture, enter cyclone separator, adsorb before returning blower fan after making not have gas phase part that condensation is got off to separate, the blended liquid phase of organic solvent and water enters layering groove.After gravitational separation, the toluene liquid automatic overflow on upper strata, to storage tank, is then seen off through positive displacement pump.The water of lower floor recycles to cooling tower after water treatment.
Absorber after desorb is owing to remaining a large amount of steam, and bed temperature is higher simultaneously, can not directly carry out adsorption operations, need to carry out absorber cooling and dry.Design utilizes external environment pure air, and the complete absorber of desorb is dried and is lowered the temperature.In casing, from the aqueous solution that condenses, by discharging from head piece of bottom half, enter spiral plate condenser and carry out coolingly, then enter layering groove.
Two adsorption boxes dry process of sorption and desorption that hockets, whole program is controlled by PLC, the operation of automatically switching.Can select according to the concentration of the air quantity of organic exhaust gas and contained toluene waste gas the number of active carbon adsorber and absorbent core.
Described medium is NACF (ACF), and NACF is a kind of novel microporous carbon material adsorbing material, due to its unique pore structure and surface characteristic, makes it aspect the removing of low concentration material, show unique performance.NACF aperture structure is single, aperture homogeneous and less, is evenly distributed on carbon fiber surface, is mainly micropore, the advantage such as have that specific area is large, adsorption desorption stroke is short, desorption and regeneration energy consumption is low, intensity is high, not shedding, life-span are long, can not cause secondary pollution, and the replacement cycle is long.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
