Surplus aqueous ammonia oil water separator
Technical Field
The invention relates to the technical field of oil-water separation, in particular to a residual ammonia water oil-water separation device.
Background
The residual ammonia water is generated in the coal pyrolysis process in the coal chemical industry field, and contains a large amount of coal gas, coal tar and condensed water in the coal gas in the coal pyrolysis process, wherein the condensed water contains a large amount of phenols and other organic matters and ammonia, so that the part of water is ammonia water, and the ammonia water is taken as a medium for circulating and cooling the coal gas.
There are many oil-water separation technologies, namely, separating oil from water or separating water from oil, but the technologies are classified into filtration or separation with different oil-water densities, such as separation by hydrophobic and oleophilic filter materials or oil-water separation by different oil-water densities, no matter what scheme is adopted in the oil-water separation technologies. However, the removal of phenol oil is difficult to achieve by simply filtering the soluble phenol substances contained in the residual ammonia water produced in the coal chemical industry.
Disclosure of Invention
In view of the above, the present invention provides a residual ammonia water oil-water separation device, which aims at overcoming the defects of the prior art, and utilizes the principle that the solubility of the phenolate oil in the ammonia water gradually increases from low temperature to high temperature or the solubility gradually decreases from high temperature to low temperature to separate out the phenolate oil partially dissolved in the ammonia water from the water, so as to realize partial separation, and then separate a part of the phenolate oil by an air floatation separation device, thereby reducing the content of the phenolate oil in the residual ammonia water and creating conditions for the subsequent water treatment.
In order to solve the technical problems, the invention adopts the following technical scheme: the utility model provides a surplus aqueous ammonia water oil water separating device, includes cooling separation equipment, cooling separation equipment includes container shell, condenser, the condenser sets up in the container shell, the condenser is the snakelike cooling tube, be the cooling water in the cooling tube, the cooling water follows low high out principle, and surplus aqueous ammonia is in cooling separation equipment's shell side follows high out principle, cooling separation equipment container shell's bottom sets up heavy oil outlet pipe, cooling separation equipment container shell's upper portion sets up light oil outlet pipe, heavy oil outlet pipe is less than surplus aqueous ammonia outlet pipe, light oil outlet pipe is higher than surplus aqueous ammonia import pipeline.
Further, the residual ammonia water oil-water separation device further comprises an air floatation separation device, the residual ammonia water which is discharged from the cooling separation device enters the air floatation separation device, and after the residual ammonia water is subjected to further air floatation separation by the air floatation separation device, the residual ammonia water enters the wastewater treatment.
Further, the bottom of the container shell of the cooling separation device is a conical structure protruding inwards of the container, and the height of the conical protrusion is higher than that of the heavy oil outlet pipeline.
The invention has the advantages that: the method is characterized in that the principle that the solubility of the phenolate oil in the ammonia water is gradually increased from low temperature to high temperature or the solubility is gradually reduced from high temperature to low temperature is utilized to separate out the phenolate oil partially dissolved in the ammonia water from water, so that partial separation is realized, and a part of the phenolate oil is separated through an air floatation separation device, so that the content of the phenolate oil in the residual ammonia water is reduced, and conditions are created for subsequent water treatment.
In addition, the bottom of the container shell of the cooling separation device is a conical structure protruding into the container, and the height of the conical protrusion is higher than that of the heavy oil outlet pipeline.

Example 1
The utility model provides a surplus aqueous ammonia water oil water separator, includes cooling separation equipment 1, cooling separation equipment includes container housing 11, condenser 12 sets up in container housing 11, condenser 12 is the snakelike cooling tube, be cooling water in the cooling tube, the cooling water follows low high principle of going out, and surplus aqueous ammonia follows high low principle of going out in cooling separation equipment's shell side, and surplus aqueous ammonia import pipeline 13 sets up in cooling separation equipment 1's upper portion, surplus aqueous ammonia export pipeline 14 sets up in cooling separation equipment 1's lower part, cooling separation equipment container housing 11's bottom sets up heavy oil export pipeline 15, cooling separation equipment container housing 11's upper portion sets up light oil export pipeline 16, heavy oil export pipeline 15 is less than surplus aqueous ammonia export pipeline 14, light oil export pipeline 16 is higher than surplus aqueous ammonia import pipeline 13, heavy oil export pipeline 15 and light oil export pipeline 16 intercommunication empty slot.
The residual ammonia water oil-water separation device further comprises an air floatation separation device 2, residual ammonia water which comes out of the cooling separation device 1 enters the air floatation separation device 2, after further air floatation separation by the air floatation separation device 2, floating oil flows out through a floating oil pipeline 21 which is arranged by the air floatation separation device 2, enters a subsurface emptying tank, and residual ammonia water is discharged through a residual ammonia water pipeline 22 which is arranged by the air floatation separation device 2 and then enters wastewater treatment.
In the embodiment, the principle that the solubility of the phenolate oil in the ammonia water is gradually increased from low temperature to high temperature or the solubility is gradually reduced from high temperature to low temperature is utilized to separate out the phenolate oil partially dissolved in the ammonia water from the water, so that partial separation is realized, and a part of the phenolate oil is separated through an air floatation separation device, so that the content of the phenolate oil in the residual ammonia water is reduced, and conditions are created for subsequent water treatment.
