This article shares with you the precautions for the use of sludge special dryers

Sludge special dryer is a kind of drying method of solid fluidization, with mechanical dispersion and drying material particle size correction function, high wet paste paste, filter cake-like material into the host machine after mixing with the heated hot air, the material in the hot air and mechanical dispersion force under the action of the formation of particle fluidization, instantaneous completion of heat and mass exchange, dried material into the trap to obtain powdery products
.
The gasification rate of the liquid increases with the decrease of atmospheric pressure (the boiling point of the material solution under vacuum decreases, so that the heat transfer driving force of evaporation increases, so that the heat transfer area
of the evaporator can be saved for a certain amount of heat transfer.
The heat source for evaporation operations can be low-pressure steam or waste hot steam and hot water circulation).

What Xiaobian wants to share with you today is the precautions for the use of sludge special dryers: 1, the capture bag must be tightened and pressed, if there is a phenomenon of sliding into the pot, it should be immediately processed to prevent running materials
.
2.
In order to ensure that the negative pressure in the container is normal and the boiling effect of the material is good, the capture bag should be cleaned once per shift, and carefully inspected, and if damaged, it should be handled or replaced
in time.
3.
When the machine is sealed, the upper and lower flanges of the cylinder must be good enough to make it fit tightly
.
When the container is lifted and fallen, do not put the head, hands and feet into the container or place it on the flange or the edge of
the top circle.
4.
Pay attention to the monitoring of the indication of the barometer and the auto pressure gauge, the vapor pressure is maintained above 0.
4Mpa, and the spray pressure is generally adjusted
between 0.
25 and 0.
5Mpa.
5.
The heating box must be preheated before working, and when the heating temperature rises to the required temperature value, it can be put into operation
.
6, before discharge, should first close the steam valve, and the inlet air temperature set to room temperature, at this time the fan continues to lead the wind, when the material is close to the normal temperature, you can turn off the fan, in case the temperature is too high, resulting in sub-high efficiency filter is burned out
.
7.
Do not touch the heating box during operation, so as not to burn the human body, and the heating box is strictly forbidden to be immersed in moisture and moisture
.
8.
If there is an unexpected situation, press the stop button to stop the whole machine operation
.
9.
There should be no tools and utensils on the equipment to avoid personal accidents on
the equipment.
