Description
Technical Field
The invention relates to a waste paint bucket cleaning process.
Background
According to the latest national catalog of dangerous wastes, waste oil barrels and waste paint barrels are containers containing or directly infected with dangerous wastes, and belong to dangerous wastes. At present, after a waste paint bucket enters a factory, waste paint is firstly poured into a collecting pool and then is put on a compression packer to be pressed into a pressing block for packing and outputting. But most waste paint bucket back, waste paint is the semi-solid state already, can't pour out completely, mainly leans on to extrude waste paint when flattening on the baling press, and this kind of method not only can harm the baling press belt, leads to the belt to glue unable rotation and influences production, still can influence the briquetting and return the production quality behind the steelworks.
How effectively get rid of the waste paint bucket economically and empty remaining waste paint after, guarantee to return the quality of steelmaking mill briquetting and become the problem that waits for immediate solution.
Disclosure of Invention
The invention aims to prepare a cleaning solution by treating and compounding steel slag tailings in solid waste resources of a steel mill, economically and effectively remove waste paint remained after a waste paint bucket is dumped through a specific cleaning process, and ensure the quality of briquettes returned to the steel mill; the invention also aims to provide a resource utilization method for the steel slag tailings.
In order to achieve the purpose, the technical scheme is as follows:
an economical waste paint bucket cleaning process comprises the following steps:
(1) Soaking the steel slag tailings in a water tank to obtain a steel slag tailings soaking solution, wherein the pH value is 11-13;
(2) Adding alkali into the obtained steel slag tailing soaking solution to increase the pH value to be more than 13;
(3) Mixing the soak solution obtained in the step (2), diethylene glycol, propylene glycol and sodium polyacrylate to prepare a cleaning solution;
(4) Placing a waste paint bucket in cleaning fluid to be heated and stirred; and taking out the waste paint after the waste paint is stripped and sending the waste paint to a briquetting workshop.
According to the scheme, the mass ratio of the steel slag tailings to the water in the step 1 is 1:3, 1 ton of steel slag tailings is soaked in a water pool with the size of 3 cubic meters for 7 days, and then the steel slag tailings soaking liquid is obtained, wherein the pH value is 11-13.
According to the scheme, the alkali in the step 2 is caustic soda flakes, sodium carbonate or other chemical reagents for increasing the pH value.
According to the scheme, the step 3 comprises the following steps in parts by weight:
100 parts of a soaking solution; 3-8 parts of diethylene glycol; 1-5 parts of propylene glycol; 1-5 parts of sodium polyacrylate.
According to the scheme, the step 4 is kept at the temperature of 70-90 ℃ and stirred for 35-45min.
According to the scheme, the method also comprises the step of filtering the cleaning solution after the step 4 and then refluxing the cleaning solution to the water pool in the step 1 for repeated use.
The steel slag tailings in the solid waste resources of the steel mill are composed of a large amount of oxides, can be made into high alkalinity after simple treatment, is doped with proper flake caustic soda and a surfactant, and can be prepared into a cleaning solution capable of cleaning paint impurities remained in a waste paint bucket according to a specific proportion. The cleaning liquid obtained by the invention can slowly soften the adhesive force between the waste paint adhered to the barrel and the surface of the barrel in a high-temperature environment, and can effectively separate the waste paint through continuous mechanical stirring.
Compared with the prior art, the invention has the following beneficial effects:
1) The main components of the steel slag tailings are CaO, mgO and other minerals, and after the steel slag tailings are fully soaked, the PH value of the solution can reach 11-13, so that the steel slag tailings have the effect of recycling solid waste resources of a steel mill. Meanwhile, the use of alkali is reduced, and the cost is saved.
2) The process utilizes the fact that the adhesive force between the waste paint adhered on the barrel and the surface of the barrel can be slowly softened under the environment of high temperature and strong alkali, and the waste paint can be effectively separated through continuous mechanical stirring.
3) Diethylene glycol and propylene glycol are surface dispersing active agents, and the adhesion force between the waste paint and the barrel surface can be eliminated in a speeded-up manner in the constant-temperature stirring process.
4) The sodium polyacrylate can soften the waste paint and flocculate the dust particles in the immersion liquid, so that the cleanness of the oil drum after cleaning is ensured.
