Description
Technical Field
The invention belongs to the technical field of foam sorting, and particularly relates to a foam sorting system.
Background
The foam separation is a separation technology by utilizing the difference of adsorption properties of separated substances on the surfaces of bubbles, namely a method for achieving the purpose of separation or concentration by carrying substances to be separated on the surfaces of the bubbles, has wide application in industrial production and daily life, and is a separation technology with great development prospect. Sorting according to the different foams of the separated materials can be divided into two categories: the separation of the system is widely used for mineral flotation separation of mine enterprises and separation and absorption of various metal ions such as copper, lead, zinc, cadmium and the like in industrial sewage.
currently, the commonly used froth separation methods include an ion flotation method using the hydrophilic and hydrophobic amphiphilic characteristics of a surfactant, a colloid adsorption flotation method adding reverse charge colloid air flotation, and a solvent air flotation separation method based on the separation of components to be separated in an aqueous phase by selectively covering air bubbles with an organic solvent. These processes are all dispersions at a certain steady state. Adding surface active substance into the solution, which forms gas-liquid-solid, gas-liquid adsorption layer with hydrophobic groups oriented to gas phase by van der Waals force, hydrogen bond and electrostatic force with target components such as mineral in ore pulp, ions, molecules and colloid in the solution, and separating the adsorption layer with the floating of air bubbles in the system. The material foam sorting process is completed in a gas-liquid-solid three-phase system, and the pressure and atmosphere change are important factors influencing the foam stability.
however, the existing foam separation technology is generally carried out under normal pressure environment, and the influence of pressure change and gas partial pressure on gas-liquid-solid interface formation, bubble floating separation and the like is not considered. Namely, the existing foam sorting technology can not accurately simulate the foam sorting process and conditions under different air pressure and atmosphere environments, and particularly is difficult to simulate the foam sorting behavior under low air pressure and low oxygen environments.
Thus, the existing foam sorting technology is in need of further improvement.

Specifically, for example, the atmosphere of the slurry in the reactor main body may be controlled by controlling the difference between the amount of air supplied to the first transfer portion and the amount of air discharged from the second transfer portion, and when the amount of air supplied to the first transfer portion is larger than the amount of air discharged from the second transfer portion per unit time, the atmosphere space is at a positive pressure; when the air supply amount of the first conveying part is less than the air exhaust amount of the second conveying part in unit time, the atmosphere space is at negative pressure; when the air supply amount of the first conveying part is equal to the air exhaust amount of the second conveying part in unit time, the pressure of the atmosphere space is kept unchanged, but the slurry in the reactor main body can be in a flowing atmosphere environment, the slurry can be foamed, the foam quantity tends to be favorable for improving the foam sorting efficiency and effect, and the purpose of improving the foam sorting efficiency and effect is achieved.

Meanwhile, when the foam sorting process does not need to exhaust, the sealing of the atmosphere space can be realized by closing the pressure reducing part, and the sealing of the atmosphere space can be further ensured by closing the air outlet control valve, and particularly, when the pressure reducing part fails and gas in the atmosphere space leaks from the pressure reducing part, the closed environment of the atmosphere space can be maintained by closing the air outlet control valve. Furthermore, the gas in the atmosphere space can be discharged completely through the air outlet valve and the power part, at the moment, the decompression part is equivalent to a gas outlet, the air is not actively exhausted from the atmosphere space, the gas in the atmosphere space can be exhausted according to the requirement of the foam sorting process by controlling the opening degree of the air outlet valve and the power part, and the exhausted gas is sent to the gas absorption part.

The inventor finds that in the foam sorting process, the slurry can be directly mixed in the reactor main body or mixed in the slurry mixing chamber, and the slurry mixed in the slurry mixing chamber is sent into the reactor main body, so that the foam sorting can be carried out after the slurry enters the reactor main body. Furthermore, through setting up size mixing chamber and third conveying part for this foam is selected separately the system and is applicable in the foam of needs side selection limit with thick liquids and select separately the process, with efficiency and the effect that improves the foam and select separately. It should be noted that the specific type of the slurry added from the slurry mixing chamber to the interior of the reactor main body during the sorting process is not particularly limited, and can be selected by those skilled in the art according to the actual needs, for example, the slurry added during the sorting process may be the slurry identical to the original slurry in the reactor main body, or may be an auxiliary agent required during the sorting process.

The inventors found that by providing the slurry control valve on the third conveyance part, on the one hand, the rate of output and the amount of output of the slurry can be controlled when the slurry is conveyed from the slurry mixing chamber to the interior of the reactor main body, and on the other hand, when the conveyance of the slurry is stopped, the slurry control valve can be closed to prevent the external atmosphere from reaching the interior of the reactor main body through the third conveyance part or to prevent the slurry in the interior of the reactor main body from flowing out in the reverse direction from the third conveyance part.
according to still another embodiment of the present invention, referring to fig. 12, the size mixing chamber 510 may be connected to the first transfer part 420 and adapted to transfer the gas of the gas supply part to the size mixing chamber. The inventor finds that by connecting the size mixing chamber with the first conveying part, on one hand, when the size mixing chamber needs gas for size mixing, the gas supplied by the gas supply part can be conveyed to the size mixing chamber through the first conveying part to react as a size mixing component; on one hand, when the slurry in the slurry mixing chamber is delivered into the reactor main body in the separation process, the atmosphere of the slurry delivered into the reactor main body by the slurry mixing chamber can be kept consistent with the original slurry atmosphere in the reactor main body as much as possible by delivering the atmosphere to the slurry mixing chamber, so that the foam separation process is prevented from being influenced by the inconsistent slurry atmosphere; on the other hand, under the condition of the same opening of the slurry control valve, the slurry mixing chamber is connected with the first conveying part, so that the speed of conveying the slurry to the inside of the reactor main body is improved.

The inventor finds that when gas is fed into the slurry in the reactor main body, bubbles are generated in the slurry in the reactor main body, and the size and the speed of the generated bubbles are related to the speed and the quantity of the gas, so that when the speed and the quantity of the gas are larger, the diameters of the bubbles can be smaller, meanwhile, the quantity of the bubbles is larger, the bubbles easily reach a bubble area without being carried with sorted substances in the floating process, the utilization rate of the bubbles is reduced, and the sorting effect is reduced under the condition of the same gas quantity. And through setting up bubble dispersion devices, be favorable to with bubble homodisperse in thick liquids, increase the surface area of bubble and separation material contact, show the bubble quantity that reduces the bubble and not carry the separation material promptly and get into the bubble district, and then improve the effect that the foam was selected separately.
