General introduction
The alcohol industry is the foundation of the national economy important raw material industry. It is widely used in chemical industry, food industry, daily chemical industry, medicine and health care and other fields. Along with the rapid development of alcohol industry, there appeared a series of problems, including the worst polluted of alcohol is one of the problems to be solved. After so many years of development, for the processing of corn alcohol worse about the following types: the first is to bad corn alcohol by solid-liquid separation, simple in filter cake moisture content 85% the left and right sides, after the separation directly do feed sales, separation of waste liquid after anaerobic or aerobic treatment (hereinafter referred to as solid-liquid separation and anaerobic treatment technology).Worse by separating the second type is the corn alcohol, separating the residue water content after generally less than 70%, after drying the do feed sales, separation of waste liquid after anaerobic or aerobic treatment (hereinafter referred to as the DDG - anaerobic treatment process). Direct evaporation, the third kind is the corn worse liquid filter residue and filtrate concentrate drying and processed into feed sales, (DDGS) process. The specific process of solid-liquid separation, the filtrate of concentration and drying section.
Working process and principle:
Alcohol wet slag is fed by feeder, screw conveyor, together with hot air from furnace, to be mixed and flow into the dryer, synthetic running backwards, the tail exhaust, called shun (and) flow drying process; Inside the cylinder, materials mixed with good contact with hot air, wet and heat exchange, the hot air will heat to the wet material, make the wet material temperature, wet material heats, contains moisture evaporates into the hot air, so as to realize the wet material drying; Cylinder body double copy board, keep the material copy behind, make the material in contact with the hot air fully, promoted the heat exchange, and make the material since before moving back. After drying of dry slag through drying cylinder seal type discharging screw conveyor, again by artificial packaging, waste gas is treated with dust removal device from the pipe into the atmosphere
