Description
Područje tehnike The field of technology
Izum se odnosi na postupak zaštite protiv korozije kod čeličnih spremnika i čelične spremnike koji se koriste za akumulaciju i obradu vode u području obrade kanalizacijske vode. The invention relates to the corrosion protection process for steel tanks and steel tanks used for the accumulation and treatment of water in the area of sewage treatment.
Stanje tehnike State of the art
Spremnici za akumulaciju i obradu vode, osobito u području obrade kanalizacijske vode, ali također u obradi pitke i tehničke vode, se proizvode iz materijala koji zavise o zahtijevanoj zapremini spremnika. Najveći se spremnici obično izrađuju od armiranog betona, a manji od čelika i plastike. Spremnici moraju udovoljavati statičkim zahtjevima, s obzirom na količinu tekućine koju bi trebali sadržavati. Štoviše, važne značajke spremnika uključuju njihovu vodonepropusnost i otpornost na koroziju, u posebnim okolnostima također i na otpornost izlaganju kemikalijama. Tanks for the accumulation and treatment of water, especially in the field of sewage water treatment, but also in the treatment of drinking and technical water, are produced from materials that depend on the required volume of the tank. The largest tanks are usually made of reinforced concrete, and the smaller ones are made of steel and plastic. Tanks must meet static requirements, considering the amount of liquid they should contain. Moreover, important features of containers include their watertightness and resistance to corrosion, and in special circumstances also to resistance to exposure to chemicals.
Čelični su spremnici obično kružni, ne veći od 1000 m3 zapremine. Zajednički je problem zaštita protiv korozije, osobito u slučaju potopljenih spremnika, što je uobičajeni način njihovog smještaja. Drugi je problem njihov transport na mjesto odredišta. Kod montaže spremnika koji se sastoji od nekoliko segmenata na mjestu odredišta, nedostatak se sastoji u visokim zahtjevima montaže, ili u zakivanju ploča zajedno, gdje se trebaju umetati i brtveni prsteni i rade se otvori za zakovice, ili njihovom zavarivanju zajedno. Štoviše, u slučaju zavarivanja, zaštita ploča protiv korozije se oštećuje i treba je obnoviti na licu mjesta. Ovo se primjenjuje i na antikorozivnu oblogu i na zaštitu protiv korozije putem plastičnog površinskog filma. Steel tanks are usually circular, not larger than 1000 m3 in volume. A common problem is protection against corrosion, especially in the case of submerged tanks, which is the usual way of their placement. Another problem is their transport to the place of destination. When assembling a tank consisting of several segments at the destination, the disadvantage consists in the high assembly requirements, or in riveting the plates together, where the sealing rings need to be inserted and holes for the rivets are made, or in their welding together. Moreover, in the case of welding, the corrosion protection of the plates is damaged and needs to be renewed on site. This applies to both anti-corrosion coating and corrosion protection by means of a plastic surface film.
Otkriće izuma The discovery of an invention
Gore navedeni nedostaci se prevladavaju postupkom antikorozivne zaštite čeličnih spremnika u skladu s predmetnim izumom. Osnova izuma se sastoji u činjenici da je svaka čelična komponenta koja oblikuje spremnik obrubljena iznutra i izvana i sa svih preostalih strana termoplastičnim dijelovima, koji su povezani na takav način, da stvaraju unutarnji prostor u kojem se smješta čelična komponenta, odvojena od vanjskog okoliša. Paneli koji se oblikuju na taj način se završno zavaruju zajedno da oblikuju zahtijevani oblik spremnika. The above-mentioned disadvantages are overcome by the process of anti-corrosion protection of steel containers in accordance with the present invention. The basis of the invention consists in the fact that each steel component forming the container is lined inside and outside and on all remaining sides with thermoplastic parts, which are connected in such a way as to create an internal space in which the steel component is located, separated from the external environment. The panels formed in this way are finally welded together to form the required shape of the tank.
Obodne se stijenke spremnika sastoje od tri sloja, u čemu su vanjski slojevi izrađeni iz termoplastike, a unutarnji je sloj izrađen od čeličnog panela. Unutarnji sloj je odvojen od vanjskog okoliša. Vanjska termoplastična ploha od kompaktnih panela, koji oblikuju stijenke, dno, a moguće i poklopac spremnika su zajedno zavareni u zahtijevani oblik spremnika. The peripheral walls of the tank consist of three layers, in which the outer layers are made of thermoplastic, and the inner layer is made of steel panel. The inner layer is separated from the outer environment. The outer thermoplastic surface of compact panels, which form the walls, the bottom, and possibly the lid of the tank, are welded together into the required shape of the tank.
Dno spremnika se povoljno proizvodi s preklopom tlocrta veličine spremnika, određenog stijenkama spremnika. The bottom of the tank is advantageously produced with an overlap of the floor plan of the tank size, determined by the walls of the tank.
Čelične ploče, osobito ako one tvore osnovu ravne stijenke bez ikakvih zakrivljenja, profilirane su za povećanu čvrstoću, ili je nekoliko profiliranih tanjih ploča stavljeno jedna na drugu. Steel plates, especially if they form the basis of a flat wall without any curves, are profiled for increased strength, or several profiled thinner plates are placed on top of each other.
Zavisno o opterećenju, panel dna i stropa spremnika su izrađeni od termoplastike ili imaju dizajn identičan stijenkama spremnika. Depending on the load, the bottom and ceiling panels of the tank are made of thermoplastic or have a design identical to the walls of the tank.
Prednosti ovih spremnika u skladu s izumom sastoje se prvenstveno u činjenici da se spremnik može izraditi u skladu sa specifičnim zahtjevima uz točno definiranu statiku za predodređeno opterećenje, slično kao u slučaju velikih armiranobetonskih spremnika. Ovime se izbjegava poddimenzioniranje ili predimenzioniranje spremnika, osiguravajući na taj način siguran rad pri optimalnim troškovima proizvodnje. Istovremeno, u potpunosti se iskorištavaju dobra svojstva termoplastike, kao što su zavarljivost, vodonepropusnost, otpornost na kemikalije i koroziju, te odlična fizikalna svojstva čeličnih materijala. The advantages of these tanks according to the invention consist primarily in the fact that the tank can be made in accordance with specific requirements with precisely defined statics for a predetermined load, similar to the case of large reinforced concrete tanks. This avoids undersizing or oversizing the tank, thus ensuring safe operation at optimal production costs. At the same time, the good properties of thermoplastics, such as weldability, watertightness, resistance to chemicals and corrosion, and excellent physical properties of steel materials are fully exploited.
Združivanje profiliranih čeličnih ploča i termoplastike rezultira savršenom prevencijom protiv korozije kao i vrlo dobrim parametrima ovog spremnika. Spremnik je lagan, uz dostizanje visokih rezultata u smislu momenata savijanja, osiguravajući također i vodonepropusnost. Čelik ima izvrsna svojstva u smislu čvrstoće, koja rezultira dobrom statikom ovog spremnika. Uporaba profiliranih čeličnih ploča povećava statičku otpornost. Korozija koja ugrožava čelične spremnike se potpuno eliminira korištenjem plastike. Isto tako, plastični materijali daju savršeno, vodonepropusno i čvrsto spajanje odvojenih segmenata spremnika. Spremnici koji se proizvode ovim načinom pokazuju vrlo dobru toplinsku izolaciju, pa se kod smrzavanja ne zaleđuju. Zavarivanje plastičnih materijala je također lako s tehnološkog gledišta i ne zahtijeva puno vremena. The combination of profiled steel plates and thermoplastics results in perfect corrosion prevention as well as very good parameters of this tank. The tank is light, while achieving high results in terms of bending moments, ensuring also water tightness. Steel has excellent properties in terms of strength, which results in good statics of this tank. The use of profiled steel plates increases static resistance. Corrosion that endangers steel tanks is completely eliminated by using plastic. Likewise, plastic materials provide a perfect, watertight and tight connection of the separate tank segments. Containers produced in this way show very good thermal insulation, so they do not freeze when freezing. Welding plastic materials is also easy from a technological point of view and does not require much time.
Ova tehnologija može proizvesti, za razliku od dosad poznatih kružnih čeličnih spremnika, čelične spremnike bilo kojeg oblika u skladu s aktualnim potrebama i svrhom za koju se koriste. This technology can produce, in contrast to the previously known circular steel tanks, steel tanks of any shape in accordance with current needs and the purpose for which they are used.
S obzirom na prethodno navedenu malu specifičnu težinu, spremnicima je lako rukovati. Spremnik je prikladan da ga se smjesti ili na tlo ili ispod zemlje, ispod razine podzemne vode, bez ikakve opasnosti od oštećenja i korozije. Zahvaljujući lakom rukovanju strukturalnim segmentima spremnika, velike se spremnike može montirati izravno na mjestu krajnjeg postavljanja, što rezultira nižim troškovima transporta. Considering the aforementioned low specific weight, the containers are easy to handle. The tank is suitable to be placed either on the ground or underground, below the groundwater level, without any risk of damage and corrosion. Thanks to the easy handling of the structural tank segments, large tanks can be assembled directly at the point of final installation, resulting in lower transport costs.

Opis pogodne izvedbe Description of suitable performance
Slike 1, 2 i 3 prikazuju jednu od tipičnih verzija kružnog spremnika koji se koristi u postrojenjima za obradu kanalizacijske vode. Stijenke 4 spremnika se sastoje od vanjskih slojeva 1 izrađenih od tankostijenih termoplastičnih panela između kojih je unutarnji sloj 2 izrađen od čelika, ili ravnih ili profiliranih čeličnih ploča. Sa strane su ploče obrubljene termoplastičnim trakama 12. Kružna stijenka 4 spremnika je povezana s dnom 5 zavarenim spojem i cjelokupni je spremnik smješten ili na zajedničku tvrdu plohu 7 kao što je pijesak, beton ili drugi prikladan materijal ili na armiranobetonsku ploču 9. Pravokutni spremnici prikazani na Slikama 4, 5 i 6 imaju jednaku konstrukciju stijenke 4 kao stijenke kružnih spremnika. Ove su stijenke 4, bez obzira na svoj oblik, međusobno povezane zavarenim spojem 3 i one su također zavarene za dno 5 ili u nekom slučaju za stropni panel 6 spremnika. Oblik spremnika može biti kružni, kvadratni ili potpuno različito zasnovan na specifičnim zahtjevima i svrsi. U pravilu, su dno 5 i stropni panel 6 jednake konstrukcije kao stijenke 4 spremnika. Dno 5 se proizvodi s preklopom 8 koji omogućuje osiguranje spremnika zatrpavanjem ili ubetoniravanjem u tlo. Ako je dno 5 izrađeno kao betonska ili armiranobetonska ploča 9, stijenke 4 se usade u utore 10 izrađene u ovoj ploči 9. Ako je spremnik vrlo velik, i njegove stijenke 4, dno 5 ili stropni panel 6 su izrađeni od nekoliko segmenata, ovi se segmenti zavaruju zajedno, a zavareni se spojevi 3 ojačavaju 11. Figures 1, 2 and 3 show one of the typical versions of a circular tank used in sewage treatment plants. The walls 4 of the tank consist of outer layers 1 made of thin-walled thermoplastic panels, between which the inner layer 2 is made of steel, or flat or profiled steel plates. On the sides, the plates are lined with thermoplastic strips 12. The circular wall 4 of the tank is connected to the bottom 5 by a welded joint and the entire tank is placed either on a common hard surface 7 such as sand, concrete or other suitable material or on a reinforced concrete plate 9. The rectangular tanks shown in Figures 4, 5 and 6 have the same construction of wall 4 as the walls of circular tanks. These walls 4, regardless of their shape, are interconnected by a welded joint 3 and they are also welded to the bottom 5 or in some case to the ceiling panel 6 of the tank. The shape of the container can be circular, square or completely different based on specific requirements and purpose. As a rule, the bottom 5 and the ceiling panel 6 are of the same construction as the walls 4 of the tank. The bottom 5 is produced with a flap 8 that enables securing the tank by burying it or embedding it in concrete. If the bottom 5 is made as a concrete or reinforced concrete plate 9, the walls 4 are inserted into the grooves 10 made in this plate 9. If the tank is very large, and its walls 4, bottom 5 or ceiling panel 6 are made of several segments, these are the segments are welded together, and the welded joints 3 are reinforced 11.
Kod analize konstrukcije stijenki 4, stropnog panela 6 i dna 5 spremnika, statička svojstva termoplastičnih materijala su beznačajna, budući da su fizikalna svojstva spremnika prvenstveno određena ugrađenom čeličnom konstrukcijom, to jest unutarnjim slojem 2. When analyzing the structure of the walls 4, ceiling panel 6 and bottom 5 of the tank, the static properties of thermoplastic materials are insignificant, since the physical properties of the tank are primarily determined by the built-in steel structure, that is, the inner layer 2.
Stijenke spremnika u zahtijevanim dimenzijama i zahtijevanom kapacitetu na statičko opterećenje izrađene su od tankostijenih termoplastičnih panela ispunjavanjem prostora šupljina, stvorenog od dva vanjska termoplastična sloja 1 s unutarnjim slojem 2 od čelične ploče, čije su stranice obrubljene termoplastičnim trakama 12. Zavarivanje ili drugo vodonepropusno povezivanje vanjskih slojeva 1 termoplastičnim trakama 12 rezultirat će odvajanjem unutarnjeg sloja 2 od vanjske okoline. Stijenke 4 se zatim kutno zavaruju na dno 5 i na stropni panel 6 koristeći uobičajeni postupak taljenja žice za zavarivanje vrelim zrakom. Isti se postupak koristi za kružnu stijenku 4. Ukoliko je spremnik potopljen u tlu, dno 5 i stropni panel 6 mogu biti izrađeni od termoplastičnog panela bez ojačavajućeg unutarnjeg sloja. The walls of the tank in the required dimensions and the required static load capacity are made of thin-walled thermoplastic panels by filling the cavity space, created by two outer thermoplastic layers 1 with an inner layer 2 of a steel plate, the sides of which are lined with thermoplastic strips 12. Welding or other watertight connection of the outer of layers 1 with thermoplastic strips 12 will result in the separation of the inner layer 2 from the external environment. The walls 4 are then fillet welded to the bottom 5 and to the ceiling panel 6 using the usual hot air welding wire melting process. The same procedure is used for the circular wall 4. If the tank is submerged in the ground, the bottom 5 and the ceiling panel 6 can be made of a thermoplastic panel without a reinforcing inner layer.
Za zahtijevano statičko opterećenje spremnika, najprije se računa hidrostatski pritisak na stijenku 4 spremnika, čemu slijedi izračunavanje pritiska specifičnog tipa tla na stijenku 4 spremnika, izabire se jedan ili više slojeva trapezne ploče prikladne za oba tipa opterećenja, evaluira se potisak podzemne vode prema gore na dno 5 praznog spremnika i naprezanje preklopa 8 dna 5 protiv podizanja spremnika potiskom podzemne vode prema gore, te se dizajnira prikladan profil trapezne ploče za dno 5 spremnika. Zatim se proračun opterećenja stropnog panela 6 spremnika izvodi na temelju težine zasipanja tlom, ili nekog drugog opterećenja , prikladan profil trapezne ploče se dizajnira za stropni panel 6, te se dizajnira proračun naprezanja zavarenih spojeva koji povezuju stijenke 4 s dnom 5 i stropnim panelom 6 i prikladni tip zavarenog spoja 3. Pridržavanje gore navedenog procesa osigurava zahtijevane parametre i svojstva spremnika u skladu s izumom. For the required static load of the tank, first the hydrostatic pressure on the wall 4 of the tank is calculated, followed by the calculation of the pressure of the specific type of soil on the wall 4 of the tank, one or more layers of the trapezoidal plate suitable for both types of load are selected, the pressure of the groundwater upwards on the bottom 5 of the empty tank and the stress of the flap 8 of the bottom 5 against the lifting of the tank by the upward thrust of the groundwater, and a suitable profile of the trapezoidal plate for the bottom 5 of the tank is designed. Then, the calculation of the load of the ceiling panel 6 of the tank is performed based on the weight of backfilling with soil, or some other load, a suitable profile of the trapezoidal plate is designed for the ceiling panel 6, and the calculation of the stress of the welded joints connecting the walls 4 with the bottom 5 and the ceiling panel 6 is designed and suitable type of welded joint 3. Adherence to the above process ensures the required parameters and properties of the container in accordance with the invention.
