Abstract
The utility model discloses an extraction solvent MIBK (methyl isobutyl ketone) flashing recovery device. Specifically, the recovery device comprises a tail gas buffer trough, a vacuum unit, a solvent receiver and two sets of condensers, wherein a tail gas inlet and an additional first condenser are arranged at the top of the tail gas buffer trough; the first condenser is connected to the vacuum unit by a vacuum tube; the vacuum unit is connected to the solvent receiver by a vacuum tube; a second condenser is connected to the top of the solvent receiver; and a salt solution low-temperature condenser coil is arranged in the solvent receiver. According to the tail gas recovery processing device provided by the utility model, the two sets of condensers and the salt solution low-temperature condenser coil are used for deep condensation of the tail gas, and the tail gas subjected to deep condensation basically does not contain MIBK, so that the tail gas meets the emission standard, thus effectively improving the utilization ratio of the solvent, saving the cost, and eliminating pollution of the tail gas to the air.
Description
Technical field
The present invention relates to a kind of tail gas recycling and treating device, relate in particular to the tail gas recycling and treating device for MIBK flash distillation, mainly belong to the technical field of chemical industry equipment.
Background technology
The low boiling point organic solvents such as MIBK can produce tail gas when flash distillation, and the generation of tail gas has increased the loss of organic solvent, air is polluted simultaneously.
In prior art, the tail gas that usually adopts condenser to produce when the flash distillation low boiling point organic solvents such as MIBK carries out condensation recovery, but only adopt condenser limited to the condensation of tail gas, still higher containing organic quantity of solvent in the tail gas of discharging after condensation, the loss of organic solvent is still larger, and tail gas still causes larger pollution to air.
Summary of the invention
The object of the invention is to propose a kind of device for recovering tail gas for MIBK flash distillation.
Object of the present invention will be achieved by the following technical programs: the retracting device of extractant MIBK flash distillation, it is characterized in that: described retracting device comprises tail gas dashpot, vacuum unit, solvent receiver and two groups of condensers, described tail gas dashpot top is provided with gas inlet and connects in addition the first condenser of establishing, described the first condenser connects vacuum unit by vacuum tube, described vacuum unit connects solvent receiver by vacuum tube, described solvent receiver top connects the second condenser, is provided with salt solution cryogenic condensation coil pipe in described solvent receiver.
Further, described vacuum unit is vavuum pump.
Apply tail gas recycling and treating device of the present invention, adopt two groups of condensers and salt solution cryogenic condensation coil pipe to carry out deep condensation to tail gas, tail gas after deep condensation is not substantially containing MIBK, thereby make tail gas reach discharge standard, effectively raise the utilization rate of solvent, save cost, eliminated the pollution of tail gas to air.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention is applied to the tail gas recycling and treating device of MIBK flash distillation.
The specific embodiment
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, so that technical solution of the present invention is easier to understand, grasp.
As shown in Figure 1, the retracting device of extractant MIBK flash distillation, especially, this retracting device comprises tail gas dashpot 1, vacuum unit 2, solvent receiver 3 and two groups of condensers.Wherein this tail gas dashpot 1 top is provided with gas inlet 4 and connects in addition the first condenser 5 of establishing, this first condenser 5 connects vacuum unit 2 by vacuum tube, vacuum unit 2 connects solvent receiver 3 by vacuum tube, these solvent receiver 3 tops connect the second condenser 6, and in solvent receiver 3, are provided with salt solution cryogenic condensation coil pipe 7.Wherein vacuum unit is preferably vavuum pump, can be also the equipment of other tool vacuum capability.
During concrete enforcement, in Fig. 1, the arrow of each pipeline is exhaust gas flow direction, when extractant MIBK flash distillation, first tail gas pass through tail gas dashpot, tail gas is accepted the first condenser deep condensation, the now contained extractant MIBK major part recovery that is condensed in tail gas, tail gas containing fraction extractant MIBK is evacuated to solvent receiver by vacuum unit, double-depth condensation at the coil condensation effect of salt solution cryogenic condensation and the second condenser, extractant MIBK in tail gas is efficiently liquefied, thereby make the atomic discharge standard that reaches of extractant MIBK content in tail gas, reduced the loss of solvent.
Tail gas recycling and treating device of the present invention not only can be applied to the vent gas treatment of MIBK flash distillation, can be applicable to equally the vent gas treatment of low boiling point organic solvent flash distillation.
By above-mentioned character express, can find out, the beneficial effect of the present invention's application: adopt two groups of condensers and salt solution cryogenic condensation coil pipe to carry out deep condensation to tail gas, tail gas after deep condensation is not substantially containing extractant MIBK, thereby make tail gas reach discharge standard, effectively improved the utilization rate of solvent, save cost, eliminated the pollution of tail gas to air.
In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the present invention's scope required for protection.
