Description
Technical field
The utility model relates to tail gas disposal technique, specifically a kind of tail gas absorbing treatment device.
Background technique
Currently, most of tail gas absorbing treatment devices, mostly use activated carbon adsorption, steam dissection process system.It is this
Mixing liquid is discharged using steam raising solvent in exhaust-gas treatment mode；After mixing liquid layering, the solvent of waste water and layering needs
Further rectifying could recycle.During entire adsorption treatment, a large amount of waste water can be generated, consumption mass energy is steamed for heating
Hair and waste water falling film evaporation.It will increase wastewater treatment difficulty and cost simultaneously, increase energy consumption.Again because being parsed using steam
The solvent of absorption, adsorption tanks exhaust contain high concentration steam, in the service life of meeting extreme influence combustable gas concentration detector, are unfavorable for
The detection of discharge gas.
Summary of the invention
The above-mentioned deficiency of steam parsing is used for existing tail gas adsorption, it is high that the utility model provides a kind of adsorption rate
By force, parsing is convenient, saves the energy, without discharge of wastewater, adapts to a variety of chemical industry tail gas processing occasions, meets energy-saving and environment-friendly tail
Gas absorbing treatment device.
The technical solution adopted in the utility model is：A kind of tail gas absorbing treatment device, it is characterised in that：Including adsorbing wind
Machine, absorption surface air cooler, adsorption tanks group, inertial gas tank, parsing surface air cooler, surge tank, vacuum pump, compressor, gas-liquid separation
Device, heater, vacuum pump surface air cooler, solvent catch tank, absorption blower suction and conveying tail gas is through absorption surface air cooler respectively through multiple air inlets
Control valve connects multiple adsorption tanks top air inlets of adsorption tanks group, and multiple adsorption tanks lower parts outlet is connected through multiple exhaust-valves respectively
Exhaust pipe, inertial gas tank is connected to multiple adsorption tanks lower part supplement parsing media through multiple parsing air intake control valves respectively, more
A adsorption tanks top parsing outlet connects parsing surface air cooler through multiple parsing leaving air control valves, and parsing surface air cooler connects surge tank,
It buffers pot bottom and connects solvent catch tank, through vacuum pump connect compressor, compressor connects gas-liquid separator warp at surge tank top
Heater connects multiple adsorption tanks and parses air inlet, and vacuum pump separates back liquid and is connected to solvent catch tank, gas through vacuum pump surface air cooler
Liquid/gas separator separates back liquid connection solvent recovery slot.
The pipeline of the inertial gas tank supplement parsing medium and the pipeline of adsorption tanks emptying valve exhaust share.
Logical vacuum pump is hinged with outside the solvent recovery slot.
When present apparatus operation, exhaust gas send absorption surface air cooler cooling by absorption blower, first passes through an adsorption tanks, solvent gas
Body is adsorbed adsorbing medium Adsorption Concentration in tank, and other not adsorbable gases pass through second adsorption tanks again and make secondary absorption
Afterwards, exhaust pipe exhaust detection is discharged into atmosphere after detection is qualified.Multiple adsorption tanks can be realized by the switch of control valve therebetween and be gone here and there
Connection absorption or son's wife in parallel, comprehensive method of investment cost and working efficiency.
After adsorption tanks adsorption solvent, which reaches technique, to be required, inertial gas tank provides inert gas and parses medium, inertia
Gas successively passes through adsorption tanks, parsing surface air cooler, surge tank, vacuum pump, compressor, gas-liquid separator, heater heating to suction
The solvent high temperature evaporation that adsorbing medium adsorbs in attached tank is parsed into mixed gas discharge adsorption tanks.
After adsorption tanks are discharged in mixed gas, by parsing cooler, control cooling temperature condenses solvent gas just, gas
Liquid mixture enters surge tank and isolates solvent liquid, and parsing medium enters after compressor increases pressure, is further separated out molten
Agent liquid.After pressurized parsing medium is heated by heater, parsing air inlet enters adsorption tanks, repeats the above steps.
During above-mentioned the solvent analysis, in order to improve the solvent analysis efficiency, resolution temperature is reduced, is reduced using vacuum pump
Pressure in resolving, promotes solvent to gasify at a lower temperature, in favor of saving the energy, improves the longevity of adsorbing medium
Life.
In above-mentioned resolving, it is arranged by reasonable technological parameter, makes to parse medium continuous work as far as possible, in turn to not
Same adsorption tanks parsing, it is possible to reduce parse the waste of medium.Before each adsorption tanks are increased the interest, first use inertial gas tank will
Air in medium displacement sorption tank same as parsing medium, to guarantee safety and extend the service life of adsorbing medium.With it is existing
Technology is compared, advantages of the present invention：
One, use scope is wide：The waste gas adsorbing and treating system is used as parsing medium without using vapor, not by the shadow of moisture
It rings, the exhaust gas for adverse effect may occur with water also can adsorption treatment.
Two, step is simple, environmental protection.Using gas parses medium and parses solvent, and the solvent after parsing does not need at rectifying again
Manage moisture therein, waste water will not be generated, have also been removed the waste water Distallation systm in general device, it is subsequent will not increase it is useless
The cost of water process and discharge.
Three, the energy is saved, is improved efficiency.Without using steam as parsing medium, steam boiler is eliminated, steaming is also eliminated
The step of drying up adsorption tanks is needed after vapour parsing, saves the energy, because of adsorbing medium moisture-free, adsorption rate is also improved very
More, adsorption efficiency improves.Because using inert gas as parsing medium, the heating source for parsing medium has many modes, can be with
It is conduction oil, can be combustion gas, can be solar energy, is also possible to the waste heat of other exhaust gas or fluid, greatly reduces the energy
Consumption.
The utility model is not brought into whole process a large amount of using inert gas as the solvent of parsing media processes absorption
Moisture, parsing object do not need to do rectifying separation moisture, do not generate waste water to need to evaporate waste water into separation solvent, be not required to yet
Handle waste water and sewage discharge.The tail gas absorbing treatment device meets environmental requirement, meets sustainable development requirement, energy conservation drop
The requirement of consumption.
