Description

Methanol rectification equipment

Technical field

The utility model relates to technical field of chemical, more particularly, relates in particular to a kind of methanol rectification equipment.

Background technology

Industrial synthesizing methanol almost all adopts the method for carbon monoxide pressurized catalysis hydrogenation, and technical process comprises operations such as gas making, synthetic purification, the synthetic and thick methanol rectification of methyl alcohol.In rectifying workshop section, present stage still uses equipment such as packed towers and plate column to carry out lock out operation in a large number, and liquid phase is carried out contact mass transfer with the gas phase of adverse current under the effect of gravitational field, reach to separate the purpose of purifying, but since gravitational field a little less than, liquid film flows slowly, and effectively contact area is little in the unit volume, so mass-transfer efficiency is very low, the weak effect of rectifying, moisture the exceeding standard of methyl alcohol finished product that causes rectifying to be come out is about 2%, do not reach specification requirement.

The utility model content

The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of methanol rectification equipment is provided, and improves rectification effect, and the methyl alcohol water content that rectifying is come out is controlled below 0.1%.

For achieving the above object, methanol rectification equipment provided by the utility model, comprise reboiler, high-gravity rotating bed, condenser and finished product jar, water vapour import on the described reboiler connects steam pipeline, the gas vent at reboiler top links to each other with air inlet on high-gravity rotating bed, the inlet at high-gravity rotating bed middle part connects feed pipe, the gas outlet at high-gravity rotating bed top links to each other with the charging aperture of condenser overhead, the discharging opening of condenser bottom links to each other with phegma inlet and the finished product jar at high-gravity rotating bed top respectively, and the liquid outlet of high-gravity rotating bed bottom links to each other with the liquid-inlet of reboiler bottom.

Adopt the utility model rectifying methyl alcohol, can guarantee methyl alcohol water content control that rectifying comes out below 0.1%, rectification effect is good, the production capacity height.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Among the figure: the 1-reboiler; The import of 11-water vapour; The 12-gas vent; The 13-liquid-inlet; 2-is high-gravity rotating bed; The 21-air inlet; The 22-inlet; The 23-gas outlet; 24-phegma inlet; The 25-liquid outlet; The 3-condenser; The 31-charging aperture; The 32-discharging opening; 4-finished product jar; The 5-steam pipeline; The 6-feed pipe.

The specific embodiment

The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not constitute any restriction of the present utility model.

Consult shown in Figure 1ly, a kind of methanol rectification equipment provided by the utility model comprises reboiler 1, high-gravity rotating bed 2, condenser 3 and finished product jar 4.Water vapour import 11 on the described reboiler 1 connects steam pipeline 5, the gas vent 12 at reboiler 1 top links to each other with air inlet 21 on high-gravity rotating bed 2, the inlet 22 at high-gravity rotating bed 2 middle parts connects feed pipe 6, the gas outlet 23 at high-gravity rotating bed 2 tops links to each other with the charging aperture 31 at condenser 3 tops, the discharging opening 32 of condenser 3 bottoms links to each other with phegma inlet 24 and the finished product jar 4 at high-gravity rotating bed 2 tops respectively, and the liquid outlet 25 of high-gravity rotating bed 2 bottoms links to each other with the liquid-inlet 13 of reboiler 1 bottom.

The utility model for the production of the time, water vapour is sent into reboiler 1 by steam pipeline 5 from water vapour import 11, make the partially liq material vaporization in the reboiler 1, material vaporization back comes out to enter high-gravity rotating bed 2 through air inlet 21 from reboiler 1, in this simultaneously, the thick methyl alcohol that synthesizing section generates enters high-gravity rotating bed 2 by feed pipe 6 from inlet 22, gas-liquid two-phase rotates at a high speed and forms specific area under the centrifugal action that produces greatly and the gas-liquid interface of bringing in constant renewal at high-gravity rotating bed 2 internal rotors, thereby realize that rectifying separates purification, gas phase (gaseous methanol after the rectifying) enters condenser 3 from the gas outlet 23 at high-gravity rotating bed 2 tops then, and liquid phase is collected the back and flowed back to reboiler 1 circulation from the liquid outlet 25 of bottom and carry out in high-gravity rotating bed 2 housing.

Enter condenser 3 from high-gravity rotating bed 2 gaseous methanols that come out, after condenser 3 condensations, a part of methyl alcohol returns high-gravity rotating bed 2 through phegma inlet 24 as phegma, and all the other methyl alcohol collect in pipeline is sent into finished product jar 4.

Claims

1. methanol rectification equipment, comprise reboiler, high-gravity rotating bed, condenser and finished product jar, it is characterized in that: the water vapour import on the described reboiler connects steam pipeline, the gas vent at reboiler top links to each other with air inlet on high-gravity rotating bed, the inlet at high-gravity rotating bed middle part connects feed pipe, the gas outlet at high-gravity rotating bed top links to each other with the charging aperture of condenser overhead, the discharging opening of condenser bottom links to each other with phegma inlet and the finished product jar at high-gravity rotating bed top respectively, and the liquid outlet of high-gravity rotating bed bottom links to each other with the liquid-inlet of reboiler bottom.
