Abstract
The utility model relates to a tail gas recovery device of a methanol tower. A methanol recovery groove which is communicated with the outlet of a methanol cooler is arranged on a transmission pipeline at the outlet of the methanol cooler; and a complete exhausting port, an overflow port and a water inlet are arranged on the recovery tank, wherein, the complete exhausting port and the overflow port on a water tank are respectively communicated with the transmission pipeline and a overflow water seal tank. The device uses a property that the methanol and the water can dissolve with each other with arbitrary ratio to completely absorb the exhausted methanol gas into the methanol recovery tank, when the methanol concentration in the water reaches a set recovery concentration, methanol water solution can be recycled again. The utility model not only protects environment, reduces the probability of accident rate, but also makes full use of resources.
Description
Technical field
The utility model belongs to gas recycling technical field, is a kind of methanol column device for recovering tail gas.
Background technology
Though through various condensations or reflow treatment, yet can produce by some tail gas in the technology of industrialized use or production methyl alcohol.And methanol recovery system of the prior art is made up of methanol column and condensed in two stages device, and during normal running, methyl alcohol complete condenser outlet delivery temperature is lower than the boiling temperature of methyl alcohol, but still has a spot of methanol gas and fixed gas discharge; If situation such as the accident of stopping in emergency or operate miss will have a large amount of methanol gas to discharge.Methyl alcohol belongs to toxic material, in case be vented in the atmosphere, not only can cause in various degree pollution to environment, and the personnel that may cause injures.
The utility model content
The purpose of this utility model provides a kind of simple in structure, safe and reliable methanol column device for absorbing tail gas.
Realize that the technical scheme that the purpose of this utility model is taked is: a Methanol Recovery groove that is communicated with it is set on the conveyance conduit in methanol condenser exit, this accumulator tank is provided with discharging hole, overfall and water inlet, wherein, discharging hole on the Methanol Recovery groove and overfall are communicated with the overflow water sealing groove by carrier pipe respectively.
Described discharging hole is connected with methanol tank with conveyance conduit by triple valve with the connection carrier pipe of overflow water sealing groove.
The methanol column device for absorbing tail gas of making according to such scheme, utilize the first alcohol and water can be arbitrarily than the character of dissolving each other, the methanol gas of discharging is all absorbed in the Methanol Recovery groove, and when treating that methanol concentration in the water reaches the recovery concentration of setting, methanol aqueous solution can be recycled again.Both protected environment, reduced the possibility that accident takes place, resource is fully used.This device has simple in structure, practical, easy and simple to handle, advantages such as good reliability.
Both protected environment, reduced the possibility that accident takes place, resource is fully used.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, methanol column device for absorbing tail gas of the present utility model, be that exhaust outlet at methanol condenser 2 is provided with a Methanol Recovery groove 1 nearby, the top of this groove is provided with water inlet 5, and be connected with outside water inlet pipe 4 by this water inlet 5, it is interior and submerge and be used for absorbing the water of methyl alcohol that the blast pipe 3 of condenser 2 puts in Methanol Recovery groove 1.The sidepiece of Methanol Recovery groove 1 and bottom are respectively equipped with overfall 8 and discharging hole 10, and are communicated with overflow water sealing groove 7 by carrier pipe respectively, make Methanol Recovery groove 1 and overflow water sealing groove 7 form linker, have the equipotential liquid level.The conveyance conduit that the discharging hole 10 of Methanol Recovery groove 1 connects is provided with emptying triple valve 9, and is connected with methanol tank by conveyance conduit.
Operation principle: when using this methanol column device for absorbing tail gas, in Methanol Recovery groove 1, add clear water earlier, and blast pipe 3 outlets of condenser 2 there are not in the entry.Utilize the first alcohol and water can be arbitrarily than the character of dissolving each other, the methanol gas of being discharged by condenser 2 can all be dissolved in the water in the Methanol Recovery groove 1, when methyl alcohol in the water reaches the recovery concentration of setting, then can open emptying triple valve 9, methanol solution is delivered to methanol tank recycles.
Claims (2)
1, a kind of methanol column device for absorbing tail gas, it is characterized in that: a Methanol Recovery groove that is communicated with it is set on the conveyance conduit in methanol condenser exit, this accumulator tank is provided with discharging hole, overfall and water inlet, wherein, discharging hole on the Methanol Recovery groove and overfall are communicated with the overflow water sealing groove by carrier pipe respectively.
2, methanol column device for absorbing tail gas according to claim 1 is characterized in that: described discharging hole is connected with methanol tank with conveyance conduit by triple valve with the connection carrier pipe of overflow water sealing groove.
