Abstract
The utility model discloses a device for producing high-purity benzene methanol, which comprises a rectifying tower. A reboiler is arranged at the bottom of the rectifying tower; a gas lifting tube is arranged at a side port of a gas phase at the bottom of the tower, and the tail end of the gas lifting tube is connected with a condenser; a light component discharging port and a backflow port are formed in the top of the rectifying tower; a feeding port is formed in the middle of the rectifying tower; and a heavy component discharging port is formed in the bottom of the rectifying tower. The device for producing the high-purity benzene methanol has the benefits that when the device works, coarse benzene methanol enters from the tower, a trace of light components are flashed off at the top of the tower and then are distilled through the reboiler at the bottom of the tower, the gas phase is produced by benzene methanol steam from a side line at the bottom of the tower and then enters the condenser through the gas lifting tube to obtain more than 99.95 percent of colorless transparent finished products, and coked heavy components at the bottom of the tower are continuously produced from the bottom of the tower. Thus, the coarse benzene methanol continuously enters from the tower, the light components are produced from the top of the tower, the coked heavy components are produced from the bottom of the tower, and the finished products are continuously produced through the side line of the gas phase at the bottom of the tower to realize the continuous operation of benzene methanol rectification.
Description
Technical field
The utility model relates to a kind of device of producing high-purity benzene methyl alcohol.
Background technology
At present, production major part of phenmethylol is Batch Process in the industry, steams through distillation still in batches and expects finished product, and continuous rectification is also arranged, and all is traditional charging from rectifying column, goes out finished product from cat head, the large percentage of borrow, energy resource consumption height.
Summary of the invention
To above-mentioned prior art; The utility model provides a kind of device of producing high-purity benzene methyl alcohol; It can make phenmethylol produce continuously; Overcome original content and look number all unsettled difficulty, guaranteed the end product quality of phenmethylol, realized the manufactureization of the continuous extraction high-purity of phenmethylol finished product.
The utility model is realized through following technical scheme:
A kind of device of producing high-purity benzene methyl alcohol comprises rectifying column, and rectifier bottoms is provided with reboiler, and gas phase side mouth at the bottom of the tower (being positioned at the reboiler top) locates to be provided with riser, and the riser end is connected with condenser; Said rectifying column top is provided with light component discharging opening and refluxing opening, and the rectifying column middle part is provided with charging aperture, and rectifier bottoms is provided with the heavy ends discharging opening.
During use, operating procedure is:
1, crude benzol methyl alcohol (the crude benzol methyl alcohol of content more than 98%) gets into rectifying column from the charging aperture at rectifying column middle part, Steam Heating, and vacuum decompression rectifying goes out micro-light component in flash overhead; Charging from rectifying column continuously, inlet amount is controlled at 1.5～2m
3/ h;
2, the above-mentioned light component that steams is from the continuous extraction of light component discharging opening, and produced quantity is controlled at 0.1～0.2m
3/ h, all the other cooled materials reflux;
3, above-mentioned cooled materials is through reboiler distillation, and then phenmethylol steam continuous extraction of gas phase side mouth at the bottom of the tower gets into condenser through riser, obtains the water white transparency phenmethylol finished product of content more than 99.95% after the condensation, and produced quantity is controlled at 1.35～1.7m
3/ h, the finished product index: main content is more than 99.95%, and look is number below No. 15;
4, the continuously heavy ends discharging opening extraction coking heavy ends at the bottom of the rectifying column, produced quantity is controlled at 0.05～0.1m
3/ h.
The device of the production high-purity benzene methyl alcohol of the utility model, during work, crude benzol methyl alcohol gets into from tower; Go out micro-light component in flash overhead, through the tower bottom reboiler distillation, phenmethylol steam is line extraction gas phase from the tower bottom side; Get into condenser through riser, obtain the water white transparency finished product of content more than 99.95%, tower bed coke heavy ends extraction at the bottom of the tower continuously; Continuous like this charging from tower, cat head extraction light component, extraction coking heavy ends at the bottom of the tower; Tower spirit phase side line goes out finished product continuously, realizes the continuous operation of phenmethylol rectifying.Compare with batch production and traditional rectifying, more stable, the end product quality fluctuation is little; Feeding intake, take out the material time of Batch Process saved in operation continuously; Reduced labor intensity of operating personnel, improved product quality, ability force rate Batch Process and traditional rectifying of production double; Stable, have that technological process is simple, cycle of operation length, energy savings, minimizing such as pollute, reduce production costs at advantage.
