Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
In the production of nickel cobalt salts by sulfate system extraction, a portion of the organic is dissolved in the solution during extraction, while the clarifier in the extraction tank has the opportunity to be mostly layered, but a small portion is entrained in the solution to enter the next process. As shown in fig. 1 to 3, an embodiment of the present utility model provides an oil removal apparatus for producing nickel salt and cobalt salt by extraction, comprising a first filter 1, an aeration tank 2, an oil-water separator 3, a stationary liquid separation tank 4, an activated carbon device and a second filter 7, which are sequentially connected, wherein a plurality of aerators 8 for exposing bubbles are arranged in the aeration tank 2.
As shown in fig. 1, the aeration tank 2 is disposed before the oil-water separator 3, and is used for separating dissolved oil in a solution, specifically, a certain amount of air is introduced into the solution, and tiny bubbles are generated under the action of the aerator 8, and the tiny bubbles adsorb organic dissolved in the solution by using gas, and have hydrophilic characteristics, while the organic has hydrophobic characteristics, and the tiny bubbles adsorb emulsified oil and dissolved oil in the solution on the bubbles to separate the solution in the process of movement.
The aeration tank 2 and the oil-water separator 3 separate and recycle the oil in the solution, thereby reducing the total amount of the oil adsorbed by the activated carbon device and prolonging the service cycle of the activated carbon.
In this embodiment, the activated carbon device includes a first activated carbon adsorption tank 5 and a second activated carbon adsorption tank 6 that are disposed in parallel, and the first activated carbon adsorption tank 5 and the second activated carbon adsorption tank 6 may be used simultaneously to increase working efficiency.
As shown in fig. 1, the liquid outlet of the first filter 1 is lower than the liquid inlet of the first filter 1, which is favorable for separating dust and slag entrained in the product liquid. The liquid outlet of the aeration tank 2 is higher than the liquid inlet of the aeration tank 2, so that the oil content of emulsified oil and dissolved oil in the solution entering the oil-water separator 3 is higher. The liquid outlet of the oil-water separator 3 is lower than the liquid inlet of the oil-water separator 3, so that less oil is entrained in the solution entering the static liquid separating tank 4. The liquid outlet of the static liquid separating tank 4 is higher than the liquid inlet of the static liquid separating tank 4. The liquid outlets of the first activated carbon adsorption tank 5 and the second activated carbon adsorption tank 6 are lower than the liquid inlet, and the residual small part of the organic substances are adsorbed by using activated carbon. The liquid outlet of the second filter 7 is lower than the liquid inlet of the second filter 7, and the second filter 7 is used for removing activated carbon residues entrained in the solution after the oil removal process.
As shown in fig. 2 and 3, the aerator 8 is disc-shaped, and the aerator 8 is uniformly distributed in the aeration tank 2 to expose a large number of uniform micro-bubbles, so that the dissolved oil is more in contact with the bubbles, and the optimal oil removal effect is achieved. Preferably, in order to prevent the tank body from being damaged during aeration, the aeration tank 2 is made of 316L stainless steel.
As shown in fig. 1, the top of the aeration tank 2 and the oil-water separator 3 are provided with valves. In normal production, there is almost no entrained floating oil, but most of the floating oil is oil dissolved in the solution by organic broken chains, the removal effect of the dissolved oil by the normal oil removal step is not ideal or the consumed auxiliary materials are increased, and the aeration tank 2 has the function of removing the organic matters dissolved in the solution, so the top of the aeration tank 2 is provided with a valve, the valve needs to be opened in the whole process of aeration, and the storage tank can be connected to recycle the oil after the valve.
In this embodiment, an outlet is provided at the top of the stationary liquid separating tank 4 for recovering the dissolved organic matters in the product.
The oil removal equipment for producing nickel salt cobalt salt by extraction provided by the utility model has the following working processes:
the product liquid is pumped into the first filter 1 through a pump and then enters the aeration tank 2, the aeration tank 2 is always filled with air in the oil removal process, a valve at the top of the aeration tank 2 is in a normally open state, the liquid enters the oil-water separator 3, oil and solution are separated by one step, a top valve of the oil-water separator 3 is opened after the operation for a period of time, organic recycling treatment is carried out, then the liquid enters the standing liquid separating tank 4, the standing liquid separating tank 4 separates the solution again to reduce the load of the oil-water separator 3, the solution enters the first active carbon adsorption tank 5 and the second active carbon adsorption tank 6 to adsorb a small amount of residual unremoved oil, and finally the solution enters the second filter 7 to remove active carbon powder entrained in the solution.
In the scheme, the oil removal equipment for producing the nickel salt and cobalt salt by extraction is suitable for removing the dissolved oil in the solution in the extraction production process, can remove and separate the dissolved and entrained organic matters in the solution under the condition that the normal operation of the extraction process is not influenced, does not influence the normal operation of the next working procedure, reduces the manpower and material resources and the time required by replacing the activated carbon, prolongs the service cycle of the activated carbon, reduces the organic loss, and saves the production cost.
While the foregoing is directed to the preferred embodiments of the present utility model, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present utility model, and such modifications and adaptations are intended to be comprehended within the scope of the present utility model.
