Stainless steel grinding oily waste slag clean resource treatment equipment

Abstract

A clean recycling treatment device for stainless steel grinding oil-containing waste residues is disclosed, including a feeding system, a vacuum distillation tank, a vacuumizing and condensing systemand a gas storage tank, wherein the feeding system utilizes a pulverizer to pulverize fiber-containing residue cake to be pulverized, and utilizes a lifting device to transfer the material into the vacuum distillation tank; the vacuum distillation tank heats the oil-containing waste residues under vacuum to a temperature at which the oil evaporates, and maintains the temperature until all the oilin the waste residues evaporates; the vacuumizing and condensing system condenses the oil steam evaporated from the vacuum distillation tank into liquid oil, and stores the condensed liquid oil in anoil storage tank; the gas storage tank stores a part of combustible gas that cannot be liquefied, and after the amount of the collected combustible gas reaches a certain value, the combustible gas isconveyed to a place where fuel is needed and used as fuel. The treatment device can recover the oil and the metal powder in the oil-containing waste residues for reuse, has no influence on the environment, has the advantages of fast processing speed, small occupied area, low cost and high production processing capacity.

Description

technical field [0001] The invention relates to the field of stainless steel treatment, in particular to cleaning and recycling treatment equipment for stainless steel grinding oily waste residue, which is suitable for stainless steel grinding, waste treatment, oily waste residue, liquid-solid separation, and vacuum distillation. Background technique [0002] In the production process of high-quality stainless steel strip, in order to obtain high-quality surface quality, surface grinding units are often used to grind the surface to remove surface oxidation, scratches and other defects, and eliminate surface color difference. Surface grinding is an important process in the production of high-quality stainless steel strip. The grinding unit cools the steel strip and abrasive belt in the grinding area by spraying grinding oil to reduce the temperature and prevent secondary oxidation on the surface of the steel strip. At the same time, the sprayed grinding oil will take the grou...

Problems solved by technology

[0004] The currently known treatment methods for oily waste residues include: incineration, biodegradation, chemical separation, extraction separation, alkaline washing, etc., but it is difficult to treat the grinding residue cake with these methods, which has no impact on the environment and can make Recycling of processed materials

Such as chemical separation, extraction separation, alkaline washing, these methods are to first transfer the oil in the waste residue to a special chemical solvent, use the special physical and chemical properties of the special chemical solvent to separate the oil from the residue, and then put Oil and solvent are separated, and the subsequent solvent regeneration process will have a greater impact on the environment; while biodegradation requires microorganisms to slowly decompose the oil in the waste residue under appropriate temperature and humidity conditions, so a larger site, the speed is relatively slow, and is affected by environmental conditions; dioxin and a large amount of smoke will be produced by incineration to treat sludge, and the oil in the waste residue cannot be recycled, and various metal elements in the waste residue will be oxidized, increasing Difficulty of follow-up use
