Description
Vynález sa týká zariadenia na prevzdušňovanie vody mikrobublinami vzduchu, alebo iného plynu obsahujúceho kyslík, v technologických zariadeniach na čistenie a úpravu vody.The invention relates to a device for aerating water with microbubbles of air or other oxygen-containing gas in process water purification and treatment plants.
Obohacovanie vody vzdušným kyslíkom je dáležitým procesom v technologii čistenia i úpravy vody. Zvláštny význam majú nové typy aeračných zariadení, ktorými sa dosiahne čo najvyššíe nasýtenie vody kyslíkom pri malej spotrebe energie. V praxi sa používajú rázné systémy prevzdušňovania vody. Najčastejšie sa používajú mechanické aerátory, alebo systémy pneumatickej aeráoie s vháňaním stlačeného vzduchu do vody cez trysky rozneho tvaru a konštrukcie. Používajú sa aj rožne systémy hydropneumatickej aerácie na principe prevzdušňovacích injektorov, v ktorých sa účinkom prúdenia vody a vzduchu vytvoří zmes vzduchových bublin vo vodě. Nevýhodou mechanických aerátorov i systémov pneumatickej aerácie a hydropneumatických injektorov je ich zložitosť, vysoké investičně a prevádzkové náklady a hlavně značná poruchovost’ a často aj nízká účinnost* a vysoká spotřeba energie. Hlavnou nevýhodou vačšiny mechanických i hydropneumatických aerátorov je vytváranie poměrně vel'kých bublin vzduchu, z ktorých je přestup kyslíka do vody podstatné menší ako v aerátoroch s mikrobublinami.Water enrichment with air oxygen is a continuing process in water purification and treatment technology. Of particular importance are the new types of aeration devices which achieve the highest oxygen saturation of the water with low energy consumption. In practice, vigorous water aeration systems are used. Mechanical aerators or pneumatic aeration systems with blowing compressed air into the water through nozzles of various shapes and designs are most commonly used. Various hydropneumatic aeration systems based on the principle of aeration injectors are also used, in which a mixture of air bubbles in the water is formed by the effect of water and air flow. The disadvantages of mechanical aerators and pneumatic aeration systems and hydropneumatic injectors are their complexity, high investment and operating costs and, above all, considerable failure rate 'and often low efficiency * and high energy consumption. The main disadvantage of most mechanical and hydropneumatic aerators is the formation of relatively large air bubbles, of which oxygen transfer to water is substantially less than in aerobics with microbubbles.
Nevýhody doposial* používaných aerátorov do značnej miery odstraňuje zariadenie na prevzdušňovanie vody pozostávajúce z najmenej dvoch prevzdušňovacích komár, ktoré sú opatřené prevzdušňovacími telesami.The disadvantages of the aerators used hitherto are largely eliminated by a water aeration device consisting of at least two aeration mosquitoes provided with aeration bodies.
Podstata vynálezu spočívá v tom, že prevzdušňovacie. komory a rovnako aj prevzdušňovacie telesá v nich uložené sú navzájom přepojené a usporiadané sériovo.The essence of the invention is that aeration. the chambers as well as the aeration bodies housed therein are interconnected and arranged in series.
Přepojením a sériovým usporiadaním dvoch, alebo viacerých prevzdušňovacích komor a přepojením a sériovým usporiadaním prevzdušňovacích telies, ktoré sú v nich uložené sa docieli intenzívně a viacnásobné premiešanie vody so’ vzduchom privádzaným prevzdušňovacími telesami.By interconnecting and serially arranging the two or more aeration chambers and by interconnecting and serially arranging the aeration bodies housed therein, intense and multiple mixing of the water with the air supplied aeration bodies is achieved.
Optimálnym riešením prevzdušňovacích komor, usporiadaním prevzdušňovacích telies v prevzdušňovacích komorách s výhodou kolmo na privod prevzdušfiovanej vody a optimálnym usporiadaním prevzdušňovacích otvorov sa docieli intenzívně a viacnásobné premiešanie vody so vzduchom a vytvoří sa zmes mikrobublín vo vodě. V porovnaní so známými aerátormi sa zariadením podl'a vynálezu výrazné zvýši přestup kyslíka do vody.The optimum solution of the aeration chambers, the arrangement of the aeration bodies in the aeration chambers, preferably perpendicular to the supply of aerated water, and the optimal arrangement of the aeration openings, intensively and multiply the mixing of water with air and a mixture of microbubbles in the water. Compared with known aerators, the device according to the invention significantly increases the oxygen transfer to water.
Zariadenie na prevzdušňovanie vody podl'a vynálezu je konstrukčně jednoduché, nemá žiadne pohyblivé časti a nevyžaduje váčší přetlak privádzaného vzduchu, ani vysokú rychlost* privádzanej vody. Jeho výhodou je vysoká funkčná spolehlivostí a účinností prevzdušfiovania vody a tiež nízké výrobně a prevádzkové náklady.The water aeration device according to the invention is structurally simple, has no moving parts and does not require a higher supply air pressure or a high supply water speed. Its advantage is high functional reliability and efficiency of water aeration as well as low production and operating costs.
Zariadenie podl'a vynálezu ilustruje ale neobmedzuje příklad prevedenia znázorněný na pripojenom výkrese, kde na obr. 1 je schématicky znázorněný jeho zvislý pozdl'žny rez a na obr. 2 zvislý priečny rez A-A.The device according to the invention illustrates but does not limit the exemplary embodiment shown in the accompanying drawing, in which: 1 schematically shows its vertical longitudinal section, and FIG. 2 shows a vertical cross-section A-A.
Zariadenie pozostáva z dvoch prevzdušňovacích komor 1^ a 2, z ktorých každú tvoří dvojica proti sebe súose umiestnených kuželových plášňov 11 a 21. Medzi nimi sú kolmo umiestnené prevzdušňovacie telesá 12, 22, ktoré majú po obvode v miestach najnižšieho tlaku rozmiestnené prevzdušňovacie otvory 13, 23. Prevzdušňovacie komory 1. a 2 sú navzájom přepojené rúrovou vložkou 3^. Prevzdušňovacie telesá 12, 22 sú navzájom přepojené přepojovacím potrubím £. Prevzdušňovacia komora 1. je opatřená prívodom vody, prevzdušňovacia komora 2 vývodem prevzdušnenej vody. Voda sa privádza do prevzdušňovacej komory 1. a jej prúd sa rozděluje do dvoch prúdov, ktoré obtekajú prevzdušňovacie teleso 12 a v zúženej časti za prevzdušňovacím telesom sa zrazia a intenzívně sa zmiešajú so vzduchom privádzaným cez otvory 13 prevzdušňovacieho telesa 12. Prevzdušnená voda prechádza rúrovou vložkou 3^ do prevzdušňovacej komory 2., kde prebieha analogický proces. Vzduch sa privádza s pretlakom, alebo sa nasáva podtlakom. častí privádzaného prietoku vzduchu prenikne do vody cez prevzdušňovacie otvory 13 na prevzdušňovacom telese 12, druhá časť prechádza přepojovacím potrubím £ do prevzdušňovacieho telesa 22.The apparatus consists of two aeration chambers 11 and 2, each of which are formed by a pair of coaxially positioned conical skins 11 and 21. Between them there are perpendicularly located aeration bodies 12, 22 having circumferentially spaced aeration openings 13 at the points of lowest pressure. 23. The aeration chambers 1 and 2 are interconnected by a tubular liner 31. The aeration bodies 12, 22 are interconnected via a transfer line 6. The aeration chamber 1 is provided with a water supply, the aeration chamber 2 is provided with an aerated water outlet. The water is supplied to the aeration chamber 1 and its stream is divided into two streams which bypass the aeration body 12 and collide intensely with the air introduced through the openings 13 of the aeration body 12 in the constricted part behind the aeration body 12. The aerated water passes through the pipe liner 3 into the aeration chamber 2, where an analogous process takes place. The air is supplied with overpressure or sucked under vacuum. parts of the supplied air flow penetrates into the water through the aeration openings 13 on the aeration body 12, the second part passes through the interconnecting line 6 into the aeration body 22.
