Problems with reaction tank after primary brine
Thread Content
This post was last edited by sunjl1981 on 2013-1-6 23:52. I would like to ask everyone, what is the diameter of the rear reaction tank of the primary brine, what is the flow rate of the brine, and is there a large amount of precipitation in the rear reaction tank? There is a large amount of precipitation in the rear reaction tank of our company. # , , &
1. The process we use is to remove magnesium first and then calcium.； 2. What comes out of the saturated barrel should be a suspension of part of the magnesium hydroxide, and enters the intermediate tank through the reaction tank. ； 3. The water from the intermediate tank is sent to the floating bucket for air flotation magnesium removal. ； 4. Add soda ash to the floating effluent in the rear reaction tank to generate a suspension of calcium carbonate, which then enters the secondary intermediate tank. ； 5. The water from the secondary intermediate tank enters the filter ； 6. The mud discharge point of the system is discharged from the upper and lower parts of the float, and the mud is discharged from the filter. There will be sedimentation in the reaction barrel, but there will not be a large amount of sedimentation. ； 7. Whether the ratio of calcium to magnesium changes, the order of the reaction changes, and whether calcium carbonate is produced. This post was last edited by limingshuguang on 2007-12-19 13:41 ]
There are sediments in the front and rear reaction tanks of our company, and they need to be cleaned every year for maintenance. Especially the front reaction tank has more sediments.
It is recommended to check the mixer for mechanical failure or selection issues
Our general rule here is that the brine should have a reaction time of 30 minutes in the reaction tank. Know the size of the reaction tank based on the maximum flow rate. There is a large amount of sedimentation in the baffle trough. Then enter the clarification barrel.
The diameter of the rear reaction tank is related to the design capacity, and there will be no problem in the design. The large amount of precipitation in the post-reaction tank mentioned by the poster is due to the frequent back-mixing of the pre-processor and poor mixing with the post-reaction tank. Calcium carbonate is a small crystal particle that is not easy to precipitate, so the possibility should be ruled out.
The brine flow rate can be determined according to the filtration capacity of the filter. Since the impurity content in the brine is different, the precipitation produced will be different after refining, so it is normal for there to be precipitation in the front and rear reaction tanks. Generally, the impurities in sea salt may be larger, and the salt quality in Qinghai Lake is better. Our company also cleans the impurities in the tank once a year.
