Description

Ethanol recovery device Technical Field The utility model relates to the technical field of chemical equipment, in particular to ethanol recovery equipment. Background The ethanol is a volatile colorless transparent liquid at normal temperature and normal pressure, the ethanol and water can be mutually dissolved in any ratio, in the production process, steam is required to be introduced into ethanol recovery equipment for condensation recovery in order to recover the ethanol, patent publication No. CN219662914U discloses an ethanol recovery tank which comprises a generation tank, a recovery tank is arranged on one side of the generation tank, a spiral pipe is arranged between the generation tank and the recovery tank, the generation tank and the recovery tank are respectively fixedly connected with two ends of the spiral pipe through connecting pipes, a condensing pipe is fixedly sleeved on the outer side wall of the spiral pipe, a cooling mechanism is connected to the condensing pipe, and a temperature sensor is fixedly arranged on the inner side wall of the spiral pipe. In the prior art, ethanol steam enters the recovery equipment for recovery, the ethanol steam is condensed by the condenser mechanism and then is liquefied for recovery, and the rest gas is discharged, so that the phenomenon that the ethanol is not completely liquefied easily occurs when the current ethanol steam enters the ethanol recovery equipment at too high flow speed, and meanwhile, the ethanol steam directly enters the recovery equipment for impacting the inside of the equipment, so that the whole airflow inside the recovery equipment is disordered, and the recovery effect of the ethanol is affected. Disclosure of utility model The present utility model provides an ethanol recovery apparatus for solving the above-mentioned problems in the background art. In view of this, the present utility model aims to propose an ethanol recovery apparatus, in which the ethanol recovery apparatus includes a support table and a recovery tank provided on the support table, a condensing mechanism is provided in the recovery tank, and a drain pipe is provided at the bottom of the recovery tank; The ethanol recovery device comprises a liquid discharge pipe, and is characterized in that an air inlet unit is arranged on the liquid discharge pipe, an air exhaust pipe is arranged at the upper end of the recovery tank, the air inlet unit comprises a connecting pipe, a buffer cover and an air inlet pipe, the connecting pipe is connected with the ethanol generation tank and used for conveying ethanol steam, the buffer cover is arranged outside the liquid discharge pipe, a buffer cavity is formed between the buffer cover and the outer wall of the liquid discharge pipe and is communicated with the connecting pipe, the connecting pipe is arranged in the tangential direction of the peripheral part of the buffer cover, two air inlet pipes are symmetrically arranged at the outer part of the liquid discharge pipe in the tangential direction of the peripheral part of the liquid discharge pipe, and the air inlet pipes are communicated with the buffer cavity and the liquid discharge pipe.
