The absorbent has the characteristics of non-toxicity, and combustion and explosion resistance, has the advantages of simple production technology, wide raw material sources, low production cost, environment-friendliness, good processing effect on waste oil, and high yield, is capable of saving a large amount of production cost for enterprises, and saves energy for nation.
Description
Technical field
Patent of the present invention is a kind of adsorbent and production method thereof for reducing trace meter content in used deteriorated oil in power system.
Background technology
Along with the development of power industry, the demand of oil for electric power constantly increases, and that the oil for electric power under the service condition in uniform temperature, atmosphere and electromagnetic field inevitably can occur is deteriorated.Regeneration to deteriorated oil for electric power is an effective economy, can produce significant economic benefit, and can protection of the environment.Utilize the high-efficiency adsorbent deteriorated oil for electric power of regenerating, not only oil consumption is little, technique is simple, and quality of reclaimed approaches fresh oil, for enterprise saves a large sum of production cost spending, for country saves valuable petroleum resources, and has protected natural environment.Domestic many power supply units can only rely on the method for mechanical filter to the method for the reduction tenor of deteriorated waste and old oil at present, and as vacuum oil-filter, accurate oil filter, its method is time-consuming, and contaminated environment.Some unit adopts silica gel, 801 adsorbents etc., but effect is poor.
Summary of the invention
Purpose of the present invention, a kind of tenor in deteriorated oil that reduces will be provided exactly, waste oil indices after adsorption treatment all is up to state standards, and there is adsorbent and the production method thereof that can reduce trace meter content in deteriorated oil of nontoxic, the nonflammable characteristics such as explosive.Technology final result scheme of the present invention is such; A kind of adsorbent and production method thereof that reduces trace meter content in deteriorated oil is characterized in that adsorbent is mixed with by weight by following raw material:
24 parts of the sulfuric acid solutions that the mass percent specific concentration is 18%-22%, 22 parts of the aluminum sulfate solutions that the mass percent specific concentration is 6% ~ 8%, 26 parts of the sodium silicate solutions that mass percent concentration is 4%-7%, 1.55 parts of the ammoniacal liquor that concentration is 21%-30%.
Its production method is carried out according to the following steps:
A, sulfuric acid solution is poured in aluminum sulfate solution, adds again sodium silicate solution after stirring, the rear ammoniacal liquor that finally adds that stirs, rear one-tenth mixed liquor stirs;
B, by aging in mixed liquor suction reactor, aging temperature is controlled at 80 ℃-90 ℃, ageing time is at 8-9 hour;
C, agingly dry after service sink water from reactor after complete, put into baking oven and toast, temperature is controlled to 130 ℃-140 ℃ and toasts dry;
After d, oven dry, with after phosphoric acid dip, water cleans;
E, put into baking again, temperature is controlled at 135 ℃, and baking time has just become the adsorbent finished product after 24 hours.
A kind of adsorbent that reduces the waste oil tenor that uses the present invention to produce, there are nontoxic, the nonflammable characteristics such as explosive, the characteristics that metallics in waste oil had to stronger adsorption capacity, adsorbent is fully contacted with waste oil, thereby except the purpose of deoiling middle metallics, reaching and falling metal and improving insulaion resistance.Not only production technology is simple, and raw material sources are extensive, and low production cost does not have environmental pollution, and processes the effective of waste oil, and yield rate is high, can be enterprise and saves a large amount of producing costs, for country saves the energy.
Lower number of cases certificate is, at the adsorbent that uses the present invention to produce, deteriorated oil is carried out to the forward and backward contrast situation of adsorption treatment;
