Background
Lithium is the lightest metal element in nature, lithium metal and lithium salt have wide application in national economic development, and after new energy is generated, lithium is more called white petroleum and becomes another important strategic resource after petroleum and rare earth. Lithium compounds have special properties, and thus lithium has a wide range of applications and is an important raw material in industrial fields such as energy, metallurgy, batteries, and medicine. With the development of new energy sources in the world and the development of lithium ion batteries for power and energy storage, lithium carbonate serving as a core raw material has a very wide market prospect.
The lithium resource in China is very rich, accounts for 11.6 percent of the whole world, and mainly exists in ores, salt lakes and oil field water. The generalized oil field water includes the oil layer water in the oil field area and the groundwater including the non-oil layer water, and the narrow oil field water refers to the groundwater directly communicated with the oil layer in the oil field area.
The oil field brine contains rich lithium ions, and the industrial production and utilization of the lithium resource rich in the oil field brine are realized, so that the method has good economic benefit, social benefit and strategic significance. The current problems are that the content of calcium and magnesium ions in the oil field water with low mineralization is high, which is not beneficial to improving the recovery rate of lithium, while the content of lithium in the oil field water with low content of calcium and magnesium ions is often lower than 100 mg/L, and the lithium extraction cost and the recovery rate are low by using the traditional method. The lithium extraction technology in the current test state at home and abroad adopts an ion sieve adsorption method. The manganese ion sieve has the characteristics of high selectivity and large adsorption capacity in the aspect of extracting lithium from oil field water, and exchange adsorption reaction is carried out on the manganese ion sieve and lithium ions in brine by utilizing the high-specificity adsorption capacity of the manganese ion sieve in an alkaline environment, so that the lithium ions are fixed by an adsorbent; then strong acid solution is used for exchanging and desorbing lithium ions, and the content of the lithium ions in the desorbed solution is obviously increased, so that the required lithium-rich solution is obtained; and purifying and concentrating the lithium-rich liquid to obtain the battery-grade lithium carbonate. The adsorption and desorption of lithium ions are completed in the adsorption and desorption tower, so the key point of the lithium extraction technology by the ion sieve adsorption method lies in the development of the adsorption and desorption tower.
The main points of the design of the adsorption and desorption tower and the problems existing at present:
1. and proper adsorption and desorption fillers are selected in the adsorption tower as the fillers for lithium ion adsorption and desorption.
2. The reaction in the tower needs to be absorbed in an alkaline environment, then the desorption is carried out in an acidic environment, the tower material needs two corrosion media of sodium hydroxide and hydrochloric acid, and the subsequent working section is not allowed to generate iron ions, so the material of the tower body is difficult to select.
3. The ionic sieve packing is the core of reaction in the tower, and excessive filling can lead to the reaction insufficient, and can cause the ionic sieve crushing, and too little filling can lead to adsorbing lithium ion concentration not enough, needs to develop suitable filling structure and lets the adsorption effect of ionic sieve reach the maximize.
4. The ion sieve filler is particles with the diameter of 0.5mm to 3mm, the leakage phenomenon of the ion sieve particles is serious, the discharged lithium-rich liquid carries the ion sieve, the pipeline and a pump can be blocked, and the sealing structure of the ion sieve is particularly important.
5. Oil field water is conveyed into the tower from the bottom through a pump, and water flow is flushed into the tower in a water column shape, so that the edges of the ion sieve filler cannot be fully contacted, and a proper structure is required to be selected to ensure that the fluid in the tower is uniformly distributed.
6. The main purpose of the reaction in the tower is to firstly adsorb lithium ions and then complete the lithium ion desorption, and the volume of the acidic water desorption solution needs to be controlled on the premise of not influencing the operation, so that the lithium ion concentration in the lithium-rich solution is improved, and all extra spaces except an ion sieve in the tower need to be controlled as much as possible, so that the lithium ion concentration of the obtained solution is ensured.
