Description
Technical field
The utility model relates to a kind of stainless steel tube and produces support equipment, especially a kind of off-line type stainless steel tube cleaning equipment, specifically a kind of batch stainless steel tube degreasing equipment.
Background technology
As everyone knows, stainless steel tube has a wide range of applications in industries such as oil production, high-duty boiler, military affairs, nuclear powers.Over nearly 20 years, the stainless steel tube production of countries in the world has had very great development, and Technology and equipment all improve a lot, and a lot of fruitful novel procesies and high efficiency new installation have occurred.China's stainless steel tube is produced through 40 years of development, especially over past 20 years, be that the stainless steel seamless pipe or the production technology of welded tube have all had significant progress, output, quality and variety constantly increase and improve, and the quality of minority product has reached international most advanced level.But compare with international most advanced level, still there is bigger gap in China stainless steel tube factory at aspects such as Technology, equipment, quality producies, need undergo technological transformation and improve, to adapt to the requirement of Chinese national economy development.
Degreasing after the stainless steel tube cold working is the important procedure that can not be ignored together, the unclean steel pipe of degreasing is in ensuing heat treatment step, tend to cause the local carburetting (being commonly called as " cloudy look ") of stainless steel tube surfaces externally and internally, thereby influence the corrosion resistance of steel pipe.
Acid cleaning process is generally adopted in degreasing in the stainless steel tube production process at present, and with hydrofluoric acid and nitric acid, the ratio according to certain is used.When steel pipe carries out degreasing, directly be dipped into the steel pipe of tying up in the acid storage, the time that control is soaked according to different material, the mainly effect of peeling off by corrosion reaches the purpose of degreasing, because it is inaccurate for soak time control, acid strength also can occur along with the prolongation of duration of service changing, and so not only can make the steel tube surface degreasing unclean, and can cause the corrosion phenomenon of steel tube surface, having reduced the corrosion resistance of steel tube surface, is a kind of extremely irrational degreasing process.
Pickling is a kind of more ancient technology, and the acid of use is essentially volatile matter, and volatility such as example hydrochloric acid, nitric acid, hydrofluoric acid are all very big, so in steel pipe degreasing workshop, workshop tart flavour is very big, production environment and operator caused very big harm.
It is reported that on November 14th, 2006, Wuxi City copper material worker Lee of company limited causes taking place acute lung edema because of inhaling people's high density mixing acid mist when carrying out the copper material pickling, die after ineffectual treatment.Assert that the fracture of hook accident appears in the patient in the pickling operation process, under the situation of the sliding people's pickling tank of workpiece, do not use protective respirator, long-time near pickling tank salvaging workpiece, cause inhaling a large amount of high density nitric acid of people, sulfuric acid mixing acid mist.According to the diagnostic classification standard of " management of occupational acute chemical toxic respiratory system disease Case definition ", can be diagnosed as the mixing acid mist and cause acute lung edema, adult respiratory distress syndrome belongs to severe intoxication, and causes death.Spent acid subsequent disposal after using in addition is more loaded down with trivial details, and need be neutralized to the pH value with lime in the acid-base neutralisation pond is 6～8, makes Industrial Residue Brick again.But have the factory of these waste water treatment engineerings less, in certain areas, when environmental administration supervision is tight, the time have factory stealthily to discharge sour water thing take place, cause a large amount of fishes and shrimps death, water surrounding has been caused serious harm.Along with the increasingly stringent of country for environmental protection, the technology of this serious environment pollution of pickling will progressively be eliminated.
For this reason; people begin to adopt organic solvent to carry out degreasing (as trichloroethane, trieline, tetracol phenixin etc.); utilize solvent to the smeary solvency action; reach the purpose of degreasing; therefore the surface of stainless steel tube is not damaged, simultaneously, because organic solvent is just volatilizable at normal temperatures; so the cleaning of the steel tube surface after the degreasing is dry, be suitable for the bright heat treatment operation of hydrogen shield.But organic solvent such as trieline (trichloroethylene according to the study, TCE) be unsaturated halogenated aliphatic hydrocarbon compound, be a kind of colourless, volatile, be insoluble in the compound probability organic solvent of water, be usually used in electroplating or the decontamination of the first five metal working part of paint spraying, the sanitising agent of Stainless Steel Products, printed circuit board (PCB) cleans, electronic component is made, leather is made, clothing dry-cleaning, the spot decontamination, preparation carpet scale remover, sterilant, organic synthesis, printing-ink, viscose is made, makeup are made, refrigerator refrigerant, organic solvent and preparation type-writer correcting fluid and write the correcting fluid etc. of usefulness.The contact of trieline is mainly occupational and exposes, make, store and use trieline all can have an opportunity to contact, especially with plating, five metals, Stainless Steel Products and electronic industry workman for very.Owing to think that this material belongs to the lower toxicity chemicals for a long time, in the process of using and producing, its toxicity is not caused due attention, from domestic reported first trichloroethylene poisonings in 1994 and since causing drug rash sample occupational dermatitis, in China the case that nearly hundred trielines cause Health cost has taken place.
Studies show that organic solvent still has bigger harm to human body and environment, for example, the personnel of contact trieline can cause following damage:
(1) but low dosage contacts the trieline compensatory in early days induces antioxidase, make intravital anti-oxidant mechanism be in compensatory excited state, reduce Content of MDA.Long-term high dosage contact trieline can cause antioxidase activity (mainly being CAT etc.) to descend, and the oxidation system of defense is impaired, removes function through and hydrogen peroxide basic from the mountain and reduces, and level of lipid raises and lipid peroxidation injury.
(2) trieline has hereditary toxic action, and long-term high density contact can cause rhexis and dna damage.The SCGE analytical method is worth further research and confirmation as the early stage index of biological monitoring of trieline exposed population group dna damage.The sensitivity that the monitoring of peripheral blood binuclear lymphocyte micronucleus is surveyed index as early stage biological prison of trieline exposed population group chromosome damage is better than conventional micronucleus test, and its early stage index of biological monitoring as TCE exposed population group chromosome damage is worth further research and confirms.
(3) long-term high density contact trieline can produce obviously influence to resurrectionist's neurobehavioral function, and the simple reaction time that mainly shows as reflection trick movement velocity and Harmony and attention prolongs mean time.
(4) long-term high density contact trieline can cause the neurasthenic syndrome, Respiratory symptoms, reproductive function disorder of occupational population, symptom recall rate such as allergic to increase.
(5) trieline has synergy to the hearing loss that noise causes.
This shows; though organic solvent degreasing has bigger superiority; but still there is certain application risk in it, and especially the healthy meeting to the operator works the mischief, and the scale of investment of equipment requires very big simultaneously; for this reason; people have developed the aqueous degreasing agent of good environmental protection at present, and it has solved the dual difficult problem of facility investment and environment protection well, in order to demonstrate fully the performance of aqueous degreasing agent; be badly in need of exploitation corresponding cleaning equipment, so that this technology is applied as early as possible.
