Description
Technical field
The invention belongs to the methanol gas disposal technology in gas purification technique field, in particular to a kind of methanol air water is washed
Tank.
Background technique
Methanol has a wide range of applications in petrochemical industry, is not only important industrial chemicals, but also is that performance is excellent
The good energy and vehicle fuel.With the rise of coal chemical industry, methanol more highlights its important value as intermediate raw material.Methanol has
The toxicity of toxicity, methanol influences maximum to the nervous system of human body and hematological system, it takes in through alimentary canal, respiratory tract or skin
Toxic reaction will be generated, the respiratory mucosa and eyesight that methanol vapor energy loss victimizes.It must be worn in the work on the spot for having methanol gas
Breathing mask.
The storage tank that petrochemical industry is used to store methanol is passed through frequently with nitrogen-sealed, and storage tank can be discharged when superpressure is discharged
Harmful gas containing methanol (mixed gas of methanol gas and nitrogen) out, it is necessary to can just be discharged into atmosphere by purified treatment.Currently, often
Method that the characteristics of being dissolved each other completely using methanol and water is washed with water handles gas containing methanol (and methanol gas).Chinese patent
CN104275073A discloses a kind of methanol aspiration method and device, has been horizontally disposed in horizontal water washing tank used with sieve
The methanol tracheae in hole and fresh water pipe with sieve pore.Methanol tracheae with sieve pore be located at water-bath water in water washing tank surface it
Under, the fresh water pipe with sieve pore is arranged in water-bath water surface.Fresh length of pipe with sieve pore, which is greater than, has sieve pore
Methanol tracheae length, with sieve pore fresh water pipe sieve pore spray radiation areas envelope methanol air sifter bore region.Normally
In the case of, methanol gas is absorbed by water-bath；Methanol gas is eluted when saturation state needs to replace when methanol aqueous solution reaches
Washing.When water-bath absorbs, methanol gas is entered in water-bath water by the methanol tracheae with sieve pore to be absorbed.When elution washing, methanol
Gas from sieve pore methanol tracheae enter water-bath water and from water-bath water evolution flow up, with sieve pore fresh water pipe to
Fresh water (washing water) counter current contacting of lower spray is absorbed.But there are the following problems for the technology: (1) gas containing methanol enters and has
There is no enough spaces to be buffered after the methanol tracheae of sieve pore, the pressure oscillation in pipe everywhere is larger；(2) when gas containing methanol from
Air-flow is unstable, uneven when sieve pore flows out, and is easy to escape and the sieve pore airless of distant place from sieve pore nearby, flow disorderly
Disorderly, poor with the contact condition of water-bath water；(3) when above-mentioned gas containing methanol is flowed up from water-bath water evolution and with sieve pore
The washing water counter current contacting that sprays downwards of fresh water pipe when carrying out elution washing, it is uneven due to gas overflowing, with elution
The contact condition of water is also poor.This will affect absorption of the water to methanol gas, keep water washing effect poor；(4) with sieve pore
The washing water that fresh water pipe sprays downwards be difficult the gas containing methanol that will flow up always completely effectively covering and high-efficient contact,
Some gas containing methanol have when elution washing without washing i.e. discharge water washing tank, water washing effect is difficult to reliably be guaranteed.
