Description

Technical Field

[0001] The utility model belongs to the field of alcohol production equipment, and specifically relates to a crude alcohol reflux device for an alcohol production line. Background Art

[0002] In my country's wine industry, the following methods are mainly used to produce alcohol: first, the material is fermented in a fermentation tank, and the fermented liquid is sent to a crude distillation tower for distillation. After direct distillation, the gas material is sent upward to the aldehyde tower, and the remaining waste liquid is discharged from the crude distillation tower. In this operation mode, after the steam is directly distilled, the steam is heated and becomes condensed water mixed in the discharged waste liquid, increasing the water content in the waste liquid. When the waste liquid is heated again for concentration, more heat energy will be consumed, and at the same time, an alcohol mixture containing impurities such as raw materials and gas foam will remain in the crude distillation tower; in production, large-volume equipment is generally used to increase alcohol production capacity. After the alcohol production capacity is increased, the amount of crude alcohol condensed in the crude distillation condensation system increases significantly, and the space between the crude distillation condensation system and the aldehyde tower is easily evacuated, causing pump cavitation and affecting the service life of the pump.

[0003] Patent No. CN201320568169.8 discloses a crude alcohol distillation tower for wine production in a winery, including a tower body, a steam inlet and a feed inlet are arranged on the lower side of the tower body, a backwash port is arranged on the bottom, and a steam exhaust pipe is installed on the top of the tower body. A tubular heat exchange chamber is vertically connected in the steam exhaust pipe, and both ends of the heat exchange chamber extend out of the steam exhaust pipe and are provided with inlet and outlet ports. In this technical solution, water vapor enters the tower body through the steam inlet, and the material enters the tower body through the feed inlet. After a period of distillation, water vapor is discharged from the upper steam exhaust pipe. During the discharge process, the steam exchanges heat with the fresh reaction gas from the outside through the heat exchange chamber, completing the waste heat utilization and avoiding heat energy loss. The device retains the steam heating method, and the problem of steam turning into condensed water mixed in the discharged waste liquid still exists. Utility Model Content
