Molasses alcohol waste liquid five-effect evaporation device

I. Overview

The waste liquid of molasses alcohol has strong corrosiveness, high chromaticity and is difficult to be removed by physicochemical and biochemical methods. Concentrated incineration or high efficiency liquid fertilizer is the optimal treatment plan at present.

The device adopts a five-effect forced circulation depressurized evaporation system, with saturated steam as the heat source, one-effect heating and five-effect working. The concentration of 5~6% molasses alcohol waste liquid is concentrated and evaporated, and the concentrated pulp with a concentration of ≥60% is sent to the boiler for incineration, and the heat generated basically meets the steam of the device. The condensed water is evaporated back to the front section for diluting water.

III. Process characteristics

1. The discharge effect is set up with spare evaporator, which can realize non-stop cleaning and ensure continuous production.

2. The device adopts automatic program control, saving labor cost

3. High processing efficiency and stable operation

4. Through thick slurry to boiler reuse, molasses production of alcohol can basically without adding fuel.
