NAPRAVA ZA HIGIENIZACIJO POSTFERMENTACIJSKEGA BLATA IZ OBRATA ZAHYGIENIZATION SYSTEM OF POSTFERMATION BLATE FROM THE CIRCUIT FOR

PRIDOBIVANJE BIOPLINABIOPLINE PRODUCTION

[0001] Predlagani izum se nanaša na napravo za higienizacijo postfermentacijskega blata iz obrata za pridobivanje bioplina z namenom, da se pripravi medij za gojenje alg.[0001] The present invention relates to a hygienization plant for post-treatment sludge from a biogas plant in order to prepare an algae culture medium.

[0002] Napravo po predlaganem izumu se uporablja za izločanje biološkega življa v obliki bakterij, mikrobov in drugih mikroorganizmov ter za sterilizacijo postfermentacijskega blata, ki se ga po sterilizaciji, opravljeni v predlagani napravi, uporabi kot gnojilo za gojenje alg.The device according to the present invention is used to excrete biological life in the form of bacteria, microbes and other microorganisms, and for the sterilization of post-treatment sludge which is used as a fertilizer for cultivation of algae after sterilization carried out in the proposed device.

[0003] Gojenje alg za industrijske namene zahteva zelo visoko čist in sterilen režim medijev, gnojil in vode, v katerih se jih goji. Gojenje alg je učinkovitejše, če med rastjo kolonij alg ne pride do bakterijskih okužb. Alge, tako kot vse rastline, za svojo rast potrebujejo gnojenje in oskrbo gojenja z mikroelementi, ki vsebujejo dušik in fosfor ter druge mikroelemente. Postfermentacijske odplake iz kmetijskega obrata za pridobivanje bioplina so bogate s tovrstnimi mikroelementi, dušikom in fosforjem. Vendar pa postfermentacijska voda iz kmetijskega obrata za pridobivanje bioplina kljub temu, da ima bogato vsebnost t.j. vsebnost mikroelementov, ki so ugodni za rast rastlin, vsebuje tudi bakterije in druge biološke kontaminacije z organizmi, ki bi lahko motili rast alg.[0003] The cultivation of algae for industrial purposes requires a very high, clean and sterile regime of media, fertilizers and water in which they are grown. Algae growth is more effective if bacterial infections do not occur during algal colony growth. Algae, like all plants, need fertilization and supply of microelements containing nitrogen and phosphorus and other microelements for growth. Post-fermentation effluents from the biogas production plant are rich in such microelements, nitrogen and phosphorus. However, the post-fermentation water from an agricultural plant for the production of biogas, despite having a rich content of i.j. the content of microelements that are favorable for plant growth also contains bacteria and other biological contamination with organisms that could interfere with algae growth.

[0004] Zato je na tem področju potreba po napravi, ki omogoča hitro in učinkovito sterilizacijo postfermentacijskih odplak ter njih nadaljnjo uporabo za gojenje alg. V iskanju primerne rešitve je predlagani izum razvil napravo za sterilizacijo postfermentacijskih odplak, ki omogoča hitro, učinkovito sterilizacijo odplak na kontinuiran način, in takojšnjo uporabo le-teh za nadaljnje namene.[0004] Therefore, there is a need for a device in this field, which enables fast and efficient sterilization of post-fermentation effluents and their subsequent use for algae cultivation. In the search for a suitable solution, the proposed invention has developed a sterilization device for post-fermentation effluent, which enables fast, efficient sterilization of the sewage in a continuous manner, and the immediate use thereof for further purposes.

[0005] Predmet predlaganega izuma je torej naprava za higienizacijo postfermentacijskega blata iz obrata za pridobivanje bioplina, značilna po tem, da obsega ohišje, ki ima podolgovato valjasto obliko, v kateri je razporejeno telo UV luči podolgovate valjaste oblike, pri čemer je telo izdelano iz materiala, ki je prepustno za UV sevanje, in je opremljeno z vsaj tremi predelki, izdelanimi iz materiala, ki je prepusten za UV sevanje, pri čemer je ohišje z notranje strani pokrito s plastjo, ki odbija UV sevanje, in UV luč, razporejena v telesu, obsega ovojnico luči, nitko in napajanje z energijo. Ohišje je prednostno izdelano iz stekla.[0005] The object of the present invention is therefore a device for the hygienisation of a post-fermentation sludge from a biogas plant, characterized in that it comprises a housing having an elongated cylindrical shape in which the body of the UV light of an elongate cylindrical shape is arranged, the body being made from material which is permeable to UV radiation and is equipped with at least three compartments made of a material that is permeable to UV radiation, the interior of the housing being covered with a reflective UV reflecting layer and an UV light arranged in body, envelopes of light, thread and power supply. The housing is preferably made of glass.

[0006] Ohišje UV luči je prednostno izdelano iz kremenčevega stekla.[0006] The UV lamp housing is preferably made of silica.

[0007] Telo ima prednostno vsaj štiri predelke, bolj prednostno pa vsaj šest predelkov.[0007] The body preferably has at least four compartments, more preferably at least six compartments.

[0008] Predelki so prednostno izdelani iz kremenčevega stekla.[0008] The compartments are preferably made of silica.

[0009] Predelki so prednostno enakomerno porazdeljeni po obodu.[0009] The compartments are preferably uniformly distributed along the periphery.

[0010] Predelki prednostno niso v stiku z odbojno plastjo in razmik med predelki in odbojno plastjo leži v območju 20 to 30% višine predelkov.The compartments preferably are not in contact with the reflecting layer, and the spacing between the compartments and the reflecting layer lies in the range of 20 to 30% of the height of the compartments.

[0011] Naprava za higienizacijo postfermentacijskega blata iz obrata za pridobivanje bioplina je bila zasnovana za odstranitev biološkega življa iz postfermentacijskega blata iz kmetijskega obrata za pridobivanje bioplina, da bi se proizvedlo sterilno gnojilo, bogato z mikroelementi in ugodno za rast alg.[0011] A device for the hygienization of post-treatment sludge from a biogas plant was designed to remove biological life from post-fertilization sludge from an agricultural biogas plant in order to produce a sterile fertilizer rich in microelements and favorable for algae growth.

[0012] Zgradba naprave poveča površino porazdelitve UV sevanja s pomočjo posebej zasnovanega steklenega ohišja, v katerem je razporejena UV luč. Postfermentacijska odplaka je izpostavljena UV sevanju, ki povzroči higienizacijo le-tega z ubijanjem bakterij in biološkega življa, ki zavira gojenje alg. Zato je pomembno, da je UV sevanje v stiku z največjo mogočo površino postfermentacijskih odplak iz obrata za pridobivanje bioplina, ki teče skozi napravo za higienizacijo.[0012] The structure of the device increases the distribution of UV radiation by means of a specially designed glass enclosure in which the UV light is arranged. Post-fermentation sewage is exposed to UV radiation, which causes hygienicization of it by killing bacteria and biological agents that inhibit the cultivation of algae. Therefore, it is important that UV radiation is in contact with the largest possible surface of post-fermentation effluents from a biogas plant that runs through the hygienisation plant.

[0013] Izvedbeni primer naprave po izumu, sterilizatorja postfermentacijskega blata, je predstavljen na sl. 1, kjer je prikazan prečni prerez le-te. Naprava obsega ohišje 1, na primer izdelano iz stekla, ki ima podolgovato valjasto obliko, v kateri je razporejeno telo 4 za UV luč, ki ima podolgovato valjasto obliko, izdelano iz materiala, ki je prepusten za UV sevanje, prednostno iz kremenčevega peska, opremljeno z vsaj tremi predelki 3 (na sl. 1 šest predelkov), lopate, prednostno iz stekla, ki povečajo površino dosega mase po fermentaciji, ki teče vzdolž ohišja 1, z UV sevanjem. Ker postfermentacijska odplaka iz kmetijskega obrata za pridobivanje bioplina ni dovolj prosojna, ima razvita oblika svetilke, telesa 4 za UV luč, namen povečati površino dosega posamezne plasti postfermentacijske odplake, ki teče skozi napravo, z UV sevanjem.[0013] An embodiment of the device according to the invention, a posterferational sludge sterilizer, is shown in FIG. 1, where the cross-section of the latter is shown. The device comprises a housing 1, for example made of glass, having an elongated cylindrical shape in which an UV light body 4 has an elongated cylindrical shape made of a material that is permeable to UV radiation, preferably of silica sand, equipped with at least three compartments 3 (in FIG. 1, six compartments), shovels, preferably of glass, which increase the surface area of the mass after fermentation flowing along the housing 1, by UV radiation. Since the post-fertilization effluent from the biogas production plant is not sufficiently translucent, it has a developed shape of the lamp, the body 4 for UV light, the purpose of increasing the surface area of the individual layer of post-fermentation effluent flowing through the device with UV radiation.

[0014] Postfermentacijske odplake tečejo skozi cev, ki tvori ohišje 1 sterilizatorja. Ohišje 1 sterilizatorja je z notranje strani pokrito s plastjo 2, ki odbija UV sevanje, odbojno plastjo, za sevanje, usmerjeno od UV luči, ki obsega ovojnico 5, nitko 6 in napajanje z energijo ter je središčno nameščena v ohišju 1 in zaprta v telesu 4 s predelki 3. Postfermentacijska odplaka iz kmetijskega obrata za pridobivanje bioplina teče vzdolž UV luči, razporejene v ohišju 1 sterilizatorja, ki je zaščitena s steklenim telesom 4, katero ima predelke 3, ki povečajo površino tekoče postfermentacijske odplake, na katero pada UV sevanje. Število predelkov je poljubno, toda večje je število predelkov, učinkoviteje UV sevanje doseže postfermentacijsko odplako, s čimer se poveča učinkovitost sterilizacijskega postopka.[0014] Post-fermentation effluents flow through the tube forming the sterilizer body 1. The sterilizer body 1 is coated on the inside with a layer 2 which reflects UV radiation, reflective layer, for UV-directed radiation, comprising envelope 5, filament 6 and energy supply, and centrally mounted in housing 1 and closed in the body 4 with compartments 3. The post-fermentation effluent from the biogas production plant runs along the UV light disposed in the housing 1 of the sterilizer protected by the glass body 4 by the compartments 3 which increase the surface of the liquid post-treatment sludge to which the UV radiation falls. The number of compartments is arbitrary, but the greater the number of compartments, the more efficient the UV radiation reaches the post-fertilization effluent, thereby increasing the effectiveness of the sterilization process.

[0015] Na tak način naprava za higienizacijo postfermentacijskega blata iz obrata za pridobivanje bioplina z namenom, da pripravi medij za alge, učinkoviteje in uspešneje izvaja higienizacijo odplak iz obrata za pridobivanje bioplina, ki se jih črpa skozi napravo.[0015] In such a way, a device for hygienisation of a postfermentation sludge from a biogas plant in order to prepare an algae medium, efficiently and efficiently performs sanitation of the sewage from a biogas plant extracted through the device.
