Alcohol recovery tower operating procedures
1. Check if the equipment is clean before driving.
2. Check that each valve is in the correct opening and closing position.
3. Open the vacuum valve, and the vacuum will rise to about 0.04 and then open the feed valve. When the liquid crystal is seen in the lower mirror, the feed valve is closed.
4. Open the steam drain valve next to the heater, slowly open the steam valve, and close the valve by draining the residual dirt in the steam tube.
5. Open the condenser inlet valve and drain valve and adjust according to the evaporation capacity.
6. Heating and heating in the range of the specified pressure, the heat is circulated in the heater and the evaporator.
normal operation
1. Adjust the feed valve and keep the mirror 1/2 height according to the liquid level.
2, condensate discharge, the heater under the heater drain valve every 2 hours or so, non-condensable gas, but when the steam trap is normal, automatic drainage.
3. Condensate condensate discharge, that is, observe about 2/3 of the glass tube liquid level gauge stored in the condenser under the condenser, close the vacuum valve of the secondary condensate water valve and the condensate storage tank, open the empty valve, open the bottom valve Drain and close the original position after it has been exhausted.
Alcohol recovery operation
1. Adjust the required steam pressure.
2. Control the degree of vacuum and adjust the flow of cooling water from the condenser above the evaporator.
3. During the time of evaporation, the discharge concentration is reduced, and the residual liquid can be tested in the evaporator. If there is no alcohol content, it can be exhausted, and then fed for normal operation.
Equipment cleaning
1. If the operation is normal, the heater can be cleaned once in ten days. When it is found that the heating steam pressure is significantly increased, it indicates that the scale has formed in the heat exchange tube, which affects the heat transfer, then the heater top cover should be closed to use the round steel. Brush the dirt in addition to the heating tube.
2, change the variety of cleaning: use 1% of the burning solution to boil for about half an hour.
3, stop cleaning: pump an appropriate amount of water for about half an hour, release the sewage.
