Description

Technical Field

[0001] The invention relates to the technical field of waste emulsion treatment, and in particular to a waste emulsion multi-stage treatment device and process. Background Art

[0002] An emulsion is a stable mixture of two immiscible liquids (usually oil and water) mixed with an emulsifier (surfactant). Its microstructure is that one phase is dispersed in the other phase in the form of tiny droplets (such as oil-in-water type or water-in-oil type). It is used in metalworking fluids (cutting fluids, rolling fluids), hydraulic oils, rust inhibitors, cosmetics (emulsions), and foods (milk, mayonnaise).

[0003] After long-term use of industrial emulsions (such as metalworking fluids), the base oil will oxidize and decompose, and the additives will be exhausted, resulting in a decrease in lubrication and cooling performance. Solid impurities such as debris and abrasive particles will be mixed into the metal processing (concentrations exceeding 0.5% will need to be scrapped). Waste emulsions have recycling value. 200-400kg of base oil can be recycled for every ton of waste liquid, thus saving crude oil consumption.

[0004] When the waste emulsion is subjected to multi-stage treatment, the waste emulsion needs to be precipitated first to precipitate large particles of debris or solids, but the precipitation process is time-consuming, resulting in a reduction in the efficiency of the multi-stage treatment of the waste emulsion during the waste emulsion recovery process. Therefore, those skilled in the art provide a waste emulsion multi-stage treatment device and process to solve the problems raised in the above background technology. Summary of the invention

[0020] A multi-stage treatment process for waste emulsion,

[0021] The steps for using the waste emulsion multi-stage treatment device are as follows:

[0022] S1: waste emulsion enters diversion bucket 1 through the pre-storage tank, opens the valve to allow the liquid to be evenly diverted to the surface of the coarse filter through diverter 1, starts the motor to drive the rotating shaft, drives the impact plate of the striking shaft to periodically hit the force-bearing ball, causes the coarse filter to generate vertical vibration through spring 1, intercepts large particles of impurities, and the liquid after the initial screening flows into diversion bucket 2 through the diversion cover, and the coarsely filtered impurities are discharged through discharge pipe 1;

[0023] S2: The pre-screened liquid enters the fine filter screen, and the impact plate is driven synchronously to impact the force-bearing ball connected to the mounting ring 2. The fine filter screen intercepts small-sized particles through the vibration of the spring 2, and the filtered liquid falls into the regulating chamber. At the same time, the pump housing 2 inputs compressed gas to the annular pipe through the air pipe to form an aeration environment. The demulsifier or neutralizer is injected into the regulating chamber through the addition pipe, and the rotating shaft drives the stirring rod to rotate to strengthen the mixing reaction of the agent and the liquid;

[0024] S3: The conditioned liquid is further transported through the output pipe, and the gas is evenly diffused through the pores before the subsequent waste emulsion treatment step is carried out. Finely filtered impurities are collected through the discharge pipe 2, and the residues in the guide groove 1 and the guide groove 2 are cleaned regularly.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The waste emulsion of the present invention enters the diversion bucket one through the pre-storage box, the coarse filter intercepts large particles of impurities, the vibration anti-blocking design prevents the filter holes from being blocked, the pre-screened liquid enters the fine filter to intercept micron-sized particles, and the vibration design further improves the filtering efficiency. During the filtering process, the diverter one and the diverter two evenly distribute the waste liquid on the surface of the coarse filter and the fine filter, so that the flow rate of the waste liquid treated by the funnel-shaped coarse filter and the fine filter is improved, and the funnel-shaped inner wall allows the intercepted solid phase to flow at a low position, which is convenient for automatic discharge, and the fine filtered liquid enters the regulating chamber, the demulsifier and the neutralizer are injected through the addition tube, and the stirring rod and the aeration device work together to enhance the reaction effect. In the initial stage of the multi-stage treatment process of the waste emulsion, it is time-consuming to separate the solid matter in the waste emulsion by precipitation, which solves the problem of low efficiency of traditional single-stage filtration and improves the multi-stage treatment efficiency of the waste emulsion.
