Alcohol dehydration steam heating device

Abstract

The invention relates to an alcohol dehydration steam heating device. The alcohol dehydration steam heating device comprises a horizontal furnace body, wherein the furnace body is divided into a front combustion chamber, a middle radiation heating chamber and a back convection heating chamber in sequence, the combustion chamber and the radiation heating chamber are divided by a porous heat storage wall, a radiation heater is arranged in the radiation heating chamber, a steam inlet and a steam outlet are formed in the radiation heater, a vertical upward flue is arranged on the top end of the convection heating chamber, heat exchangers are arranged up and down in the flue at an interval, the heat exchangers are connected in series in sequence through a steam pipeline, the heat exchanger on the bottommost end is connected with the radiation heater through the steam pipeline, a burner inlet is formed in the front end of the combustion chamber, a waste liquid gun inlet, a waste steam inlet and a circulation air compensation device are formed in and arranged on the side wall near the front end of the combustion chamber, the circulation air compensation device comprises a hot air circulating pipeline which surrounds the side wall of the combustion chamber and is in sealing connection with the side wall of the combustion chamber and a hot air inlet pipe which is tangent with the hot air circulating pipeline, an air compensation hole which surrounds the center of a circle is formed in the side wall, which is located in the hot air circulating pipeline, of the combustion chamber, and the air compensation hole communicates with the combustion chamber.

Description
