Description
Technical field
This utility model belongs to exhaust-gas treatment field, is specifically related to a kind of organic waste-gas purification recovery system.
Background technology
Fast development along with national economy, the aromatic solvents such as benzene,toluene,xylene and alcohols, lipid, acetone equal solvent in press, spray, pack, process hides, be widely used in the industrial circle such as shoemaking, these are mainly low boiling, volatile organic matter, these performance property organic compound have toxicity mostly, and wherein quite a few finally enters in air with the form of organic exhaust gas, cause the severe contamination of air.Therefore, the recycling of organic exhaust gas is imperative, reclaims organic solvent, both can reduce the pollution to environment, reclaimed again the resource of preciousness from the organic exhaust gas of industrial discharge.
The most domestic process organic exhaust gas method has: burning disposal, concentrate catalysis burning, absorption is reclaimed, biological treatment and the method such as low-temperature plasma.Burning disposal is appropriate only for little air quantity high-concentration organic waste gas and processes, and operating cost is high, and solvent can not reclaim, and resource can not reuse.The technology of biology and plasma treatment is also among inquiring into.And adsorb and reclaim advantages such as having that operating cost is low, high treating effect, solvent after recovery are reusable, both having reached cleaning produces purpose, reaches again resource circulation utilization, meets the requirement of sustainable development.
Absorbing process can be divided in the duty of adsorber by adsorbent: fixed bed；Thermopnore；Boiling (fluidisation) bed.Whether continuous by operating process is divided into Batch Adsorption process and continuous adsorption process.Generally, the suction types using fixed bed more.And the adsorbing material used is based on granule charcoal and fiber charcoal, it is the mode using and dissipating heap in the preparation due to this kind of adsorbing material, causes the random arrangement of pore in granule charcoal or fiber charcoal, when organic exhaust gas passes through, the resistance produced is relatively big, therefore consumes energy higher.
Utility model content
This utility model is intended to provide a kind of organic waste-gas purification recovery system, to solve the problem that when current air separator of oxygenerator uses granule charcoal or fiber charcoal to cause reclaiming, resistance is bigger.
A kind of organic waste-gas purification recovery system in this programme, including pretreatment system, adsorption cleaning system, desorption recovery system and dry cooling system:
Described pretreatment system includes pretreatment unit and by the first blower fan in organic exhaust gas suction pretreatment unit, and described pretreatment unit is one or more the combination therein of wet scrubber, dry collector, cooler；
Described adsorption cleaning system includes adsorption cleaning bed, and described adsorption cleaning bed is connected built with water-resistant type cellular activated carbon, described adsorption cleaning bed and the first blower fan；
Described desorption recovery system includes that vapour source, condenser, layering groove and solvent recovery groove, described vapour source, adsorption cleaning bed, condenser, layering groove and solvent recovery groove are sequentially connected with；
Described dry cooling system includes dry filter, the second blower fan and the heater being sequentially connected with, and described heater is connected with adsorption cleaning bed.
Operation principle of the present utility model: owing to part coating cloud usually can be contained in organic exhaust gas, particulate matter, the impurity such as dust, or the situations such as temperature too high (more than 40 DEG C), it is thus desirable in advance organic exhaust gas is carried out pretreatment, by the first blower fan being connected on pretreatment unit, organic exhaust gas suction pretreatment unit will carry out pretreatment, when dust in organic exhaust gas, when the impurity such as particulate matter are more, use wet scrubber as pretreatment unit, when the temperature of organic exhaust gas is higher, use cooler that it is lowered the temperature, when the solid particle polluter in organic exhaust gas is few and temperature is the highest, dry filter is used to carry out pretreatment, in use, according to the actual condition of production, above-mentioned three kinds of equipment can also be combined practical to reach maximized pretreating effect.
The impurity of solid particle class can be got rid of by pretreated organic exhaust gas, owing to adsorption cleaning bed and the first blower fan are connected, therefore can enter in adsorption cleaning bed, adsorption cleaning bed is built with water-resistant type cellular activated carbon, through hole is had for ventilating on cellular activated carbon, resistance is less, more save power consumption, also there is on it micropore of Nano grade, when organic exhaust gas is by cellular activated carbon, its interior Elements in Organic Solvents can be adsorbed in micropore, thus realize Elements in Organic Solvents and separate from organic exhaust gas, organic exhaust gas after separation is the waste gas being cleaned, can be directly discharged in air, environment is not polluted.Along with the continuous absorption of adsorption cleaning bed, after reaching degree of saturation, close pretreatment system, start that the Elements in Organic Solvents in adsorption cleaning bed is carried out desorption and reclaim.
Desorption recovery system mainly uses the mode that steam be desorbed, and steam is passed through cellular activated carbon, and high temperature can allow Elements in Organic Solvents be evaporated, and high temperature can allow the molecular motion in organic solvent more rapid, therefore can effusion from micropore faster.And after organic solvent is desorbed from cellular activated carbon, solvent-water gaseous mixture (liquid) can be formed along with the moisture in water vapour, the cooling liquefaction being then passed through condenser forms solvent-water mixed liquid.Solvent-water mixed liquid enters in layering groove, due to organic solvent and the immiscible characteristic of water, stratification in layering groove, it is achieved solvent and the separation of water.The solvent separated enters solvent recovery groove and reclaims, and the water separated can collect as otherwise utilization as waste water.
Closedown after desorption reclaims is desorbed recovery system, it is dried cooling again, in dry cooling system, after the natural wind suction dry filter that second blower fan will be extraneous carries out high-effective dust-removing, then by heater, the natural wind after filtration is thermally formed hot blast, hot blast is passed through in adsorption cleaning bed, the moisture of residual in adsorption cleaning bed can be evaporated removing, especially because also remain moisture in cellular activated carbon, after needing it is removed, just can continue on for adsorption cleaning.Treating that moisture removal is complete, close heater, cellular activated carbon is cooled down by the natural wind after direct filtration.
The beneficial effects of the utility model: can be seen that from above-mentioned operation principle, this programme by pretreatment system, adsorption cleaning system, desorption recovery system and dry cooling system with the use of, can be with the organic solvent in high efficiente callback organic exhaust gas, adsorption cleaning bed uses water-resistant type cellular activated carbon, overcoming tradition adsorbing material resistance big, consume energy high shortcoming, while cleaning organic waste gas, achieve again the recycling of organic solvent and water, the advantage with energy-conserving and environment-protective.
Further, described adsorption cleaning bed has two or more, due to when desorption reclaims, adsorption cleaning system needs to close, therefore to improve the efficiency produced, according to the situation of actual production, plural adsorption cleaning bed is set, it is achieved adsorption cleaning process and desorption removal process are alternately.
Further, filter cotton, filter cotton installation and removal enhanced convenience are installed in described dry filter, it is easy to be replaced at any time, and the effect of filter cotton dedusting is obvious, according to actual needs, the filter cotton of specification size can be selected to be installed in dry filter.
