Abstract
The invention provides a cycle utilization method of an engine ultrasonic cleaning agent / liquid. The method comprises the following steps of: a) adding a sulphuric acid solution into ultrasonic cleaning waste water, and adjusting a pH of the ultrasonic cleaning waste water to 1.5-2.5; b) heating the ultrasonic cleaning waste water added with the sulphuric acid solution; c) cooling the ultrasonic cleaning waste water and filtering. According to the invention, pollutants clinging to oil phase and water phase are removed through acidification and heating of waste water, and solid suspensions are removed through filtering, so that the engine ultrasonic cleaning agent / liquid can be used circularly. Processed and recovered cleaning agent / liquid with strong decontamination capability can be used in engine ultrasonic cleaning again, and has basically same cleaning effect as before. The resource recovery of the cleaning agent / liquid reduces pollution to environment, saves resource and lowers production costs.
Description
Technical field
The present invention relates to motor car engine cleaning technique field, be specifically related to engine ultrasonic cleaning agent/liquid recycle method.
Background technology
The motor car engine ultrasonic cleaning technique is a new technology of promoting the use of rapidly in recent years, utilize the chemical action of hyperacoustic physics cleanup action and clean-out system, pass through optimized choice supersonic band and power density again, can realize the thorough cleaning of dirt such as greasy dirt, carbon deposit, colloid the engine interior-exterior parts.Compare with the conventional clean mode, the dirty removal capacities of ultrasonic cleaning is stronger, and cleaning speed is fast, can clean to the position that artificial cleaning is difficult to clean to, and to the workpiece surface not damaged, protectiveness is better, saves solvent.
During cleaning clean-out system is dissolved in and forms detergent solution in the water, motor car engine is put into solution, dirt on the motor car engine is under the acting in conjunction of ultrasonic wave and clean-out system, be cleaned and form height emulsive product, along with constantly carrying out of cleaning, the cleansing power of solution descends thereupon, and after dropping to a certain degree, just no longer clean, and as the ultrasonic cleaning discharge of wastewater, pollutant load is very high in the waste water of discharging, can cause serious pollution to water surrounding.And the improvement of this motor car engine ultrasonic cleaning waste water also is the comparison difficulty.
Motor car engine ultrasonic cleaning pollutants in waste water, small portion are the greasy dirt that washes down from engine, carbon deposit, colloid etc., and major part is a ultrasonic cleaning agent.Therefore if clean-out system/liquid is separated from motor car engine ultrasonic cleaning waste water, be back to ultrasonic cleaning again, move in circles, constantly utilize, then both can alleviate environmental pollution widely, reduce the wastewater treatment expense, can play the environment protecting of changing waste into resources again, save clean-out system/liquid, reduce production costs.
At present, though ultrasonic cleaning technique is grown up gradually and in every field widespread use arranged, how reported in literature is not but seen in the waste water reclaiming that produces after the motor car engine ultrasonic cleaning, the research that utilizes again as yet.The maturation that is accompanied by ultrasonic cleaning technique is used, and wherein the Separation and Recovery of clean-out system/liquid, recycle will be subjected to paying close attention to widely and using with its high economic benefit and environmental benefit.
Summary of the invention
The problem that the present invention solves is to provide a kind of engine ultrasonic cleaning agent/liquid recycle method, clean-out system/liquid can be separated from Cleaning Wastewater, is back to ultrasonic cleaning again, reduces the pollution to environment, economizes on resources.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of engine ultrasonic cleaning agent/liquid recycle method may further comprise the steps:
A) add sulphuric acid soln in ultrasonic cleaning waste water, the pH that regulates ultrasonic cleaning waste water is 1.5～2.5;
B) the ultrasonic cleaning waste water that will add sulphuric acid soln heats;
C) treat to filter after the described ultrasonic cleaning waste water cooling.
As preferably, described a) in sulphuric acid soln be that mass percent concentration is that 98% sulfuric acid and water mix with volume ratio at 1: 1.
As preferably, the described pH that regulates ultrasonic cleaning waste water in a) is 2.
As preferably, described b) temperature of heating is 80 ℃～120 ℃ in.
As preferably, the time of heating is 20min～40min.
Engine ultrasonic cleaning agent provided by the invention/liquid recycle method removes the pollutent that is attached to oil phase and aqueous phase by the acidifying heated waste water, removes suspended solid by filtering again.Clean-out system/the liquid of treated recovery can be used for the engine ultrasonic cleaning once more, and cleaning performance is with basic identical originally, and soil removability is strong, and clean-out system/liquid recovery resource utilization has reduced the pollution to environment, economizes on resources, and has reduced production cost.
Embodiment
