Abstract
The utility model discloses an energy-saving type alcohol recovery tower, which comprises a tower bottom, a tower body, a heat exchanger, a condenser and pipelines. A heating pipe is disposed inside the tower bottom, the heat exchanger is connected with the condenser via a communicating pipeline, an alcohol preheating chamber is arranged on one side of the tower bottom, and the alcohol preheating chamber is communicated with the tower bottom via a duct. Besides, a cooling water coiled pipe is arranged inside the alcohol preheating chamber, one end of the cooling water coiled pipe is communicated with the heat exchanger via a cooling water pipe, and the other end of the cooling water coiled pipe forms an outlet outside the alcohol preheating chamber. As the preheating chamber is additionally arranged in front of the tower bottom, on the one hand, recovered alcohol can be preheated, and the preheated alcohol is easier to be heated and vaporized as quickly as possible in the tower bottom, on the other hand, the temperature of circulating cooling water inside the heat exchanger can be reduced, thereby enabling the vaporized alcohol to be cooled as quickly as possible in a heat exchange chamber. The energy-saving type alcohol recovery tower has the advantages of sufficiently employing afterheat of the cooling water and improving recovery efficiency of the alcohol.
Description
Technical field
The utility model relates to a kind of alcohol recovery device, especially relates to a kind of alcohol distillation column with energy-conserving action.
Background technology
At present, be applicable to the alcohol distillation column of industries such as pharmacy, food, light industry, chemical industry, mainly form by parts such as tower body, filter, heat exchanger, condenser and pipelines.Its operation principle is to utilize boiling point poor of alcohol, and the alcohol that needs are reclaimed heats performance in rectifier unit, after tower body rectifying, separate out alcohol in high concentration gas.In uphill process, temperature descends gradually and makes part alcohol produce backflow, make certain density Diluted Alcohol stoste carry out part vaporization and condensation repeatedly, most of alcohol steam mixed liquor through the cat head connecting pipe to condenser, after sample examination is qualified, discharge finished product alcohol through cooler, otherwise just be back to the redistillation of tower still.The tower still contains the waste water of micro-alcohol with discharge in still-process, reaches the purpose of separating of alcohol and water.But this alcohol distillation column also exists certain problem, and it is not in place that promptly the cooling water in the heat exchanger causes cooling often, to alcohol steam can not be cooled off as soon as possible, makes the alcohol temperature higher, influences the service life of product quality and equipment.
Summary of the invention
The purpose of this utility model is achieved through the following technical solutions, this energy-saving alcohol distillation column comprises the tower still, body of the tower, heat exchanger, condenser, pipeline, described tower still and body of the tower are one, be provided with heating tube in the described tower still, described body of the tower top is a heat exchanger, described heat exchanger links to each other with condenser by a connecting pipe road, be provided with water pipe in the described condenser, described condenser is provided with the alcohol outlet, described tower still one side is provided with an alcohol preheating chamber, described alcohol preheating chamber communicates with the tower still by a conduit, be provided with cooling water coil in the described alcohol preheating chamber, one end of described cooling water coil communicates with heat exchanger by cooling water pipe, and the other end forms outlet outside the alcohol preheating chamber, and described alcohol preheating chamber also is provided with the alcohol inlet.
The alcohol that needs to reclaim at first enters preheating chamber, utilize the waste heat of the water in the preheating chamber cooling water coil to carry out preheating, enter in the tower still by conduit again, heating tube in the tower still continues heating, distillation to alcohol, the alcohol of distillation vaporization enters heat exchanger by body of the tower and cools off, enter condenser through connecting tube again, become the higher alcohol of concentration after, the alcohol outlet of self cooling condenser bottom is flowed out and is utilized.Cooling water in the heat exchanger is got back in the cooling water coil in the preheating chamber and is continued alcohol is carried out preheating from cooling off water pipe.
The beneficial effects of the utility model: owing to added preheating chamber before the tower still, on the one hand the alcohol that reclaims is again carried out preheating, the alcohol of preheating helps heating vaporization as early as possible in the tower still; Help reducing the temperature of recirculated cooling water in the heat exchanger on the other hand, make alcohol cooling as early as possible in Heat Room of vaporization.Make full use of the waste heat of cooling water, improved the organic efficiency of alcohol.
