[001] This report refers to a patent for an invention consisting of an aqueous media oxygenator device, essentially defined by a high-performance reactor capable of "creating" dissolved oxygen, by supplying it in abundance to the medium, in order to promote the oxidation of algae and existing organic matter, and conduct oxidation reactions with salts and soluble metals, releasing ammoniacal nitrogen, reducing phosphorus and phosphate, precipitating iron, manganese and carbonates, allowing the subsequent removal of these compounds through such as decantation and filtration, by means of small equipment, easy installation, low energy consumption and high efficiency, having, as an application field, oxygenator in fish and shrimp farms, treatments of human or animal waste, such as fresh swine manure or post-biodigesters, in the treatment of slurry from landfills and in in the process of injection and dispersion of gases in a liquid medium, such as carbon dioxide in the refrigerant industry.
[002] O estado da técnica no tocante a meios de oxigenação de meios aquosos, efluentes em geral, dentre outros, se apresenta na utilização de variadas formas e equipamentos em que esta oxigenação pode ser realizada por agitação, turbilhonamento, injeção de ar ou oxigénio gasoso ou líquido por bombeamento forçado, com ou sem sistema de microbolhas, sistemas estes de oxigenação que também variam quanto a sua complexidade, mas todos com eficiência insuficiente. Mesmos os mais complexos carecem da possibilidade de pré-ajustes às condições de uso às reais necessidades e possíveis variantes que possam ocorrer. Logo, os modelos em uso não chegaram ao estado de eficiência na oxigenação de efluentes e meios aquosos, e, por vezes, a relação custo- benefício é outro fator impeditivo. The state of the art regarding oxygenation means of aqueous media, effluents in general, among others, is presented in the use of various forms and equipment in which this oxygenation can be performed by shaking, swirling, air injection or oxygen gaseous or liquid by forced pumping, with or without microbubble system, these oxygenation systems also vary in complexity, but all with insufficient efficiency. Even the most complex ones lack the possibility of pre-adjustments to the conditions of use to the real needs and possible variants that may occur. Therefore, the models in use have not reached the state of efficiency in the oxygenation of effluents and aqueous media, and sometimes the cost-benefit ratio is another impeding factor.
[003] Tendo como objetivo buscar oxigenação perfeita de meios aquosos, efluentes, dentre uma série de outros passivos ambientais, produzindo, consequentemente, os efeitos saneadores da oxidação em orgânicos e todos os efeitos correlatos provocando a separação de materiais sólidos dos líquidos, concebeu-se o presente pedido de patente de invenção, um dispositivo
oxigenador que atua sem a utilização de meios acessórios, aproveitando-se unicamente dos recursos naturais, como pressão atmosférica e hidráulica. [003] In order to obtain perfect oxygenation of aqueous media, effluents, among a number of other environmental liabilities, consequently producing the sanitizing effects of oxidation on organic and all related effects causing the separation of solid materials from liquids, if the present application, a device oxygenator that acts without the use of ancillary means, taking advantage of only natural resources, such as atmospheric and hydraulic pressure.
[004] Neste escopo, o presente objeto de patente de invenção serve-se da aplicação do chamado efeito Venturi para a inserção - "oxigenação"- de ar num determinado meio aquoso ou material líquido a ser tratado, com o diferencial que, no equipamento proposto em questão, este processo é feito de forma natural ou espontânea, ou seja, a oxigenação do material decorre da sucção do ar externo em virtude da pressão negativa criada na câmara de passagem do equipamento. O efeito Venturi (também conhecido como tubo de Venturi) ocorre, como é conhecido, quando num sistema fechado, o fluido em movimento constante em duto uniforme comprime-se momentaneamente ao encontrar uma zona de estreitamento, aumentando sua velocidade e, ao atravessá-la cria uma "zona de baixa pressão". In this scope, the present object of the invention is to apply the so-called Venturi effect for the insertion - "oxygenation" - of air into a given aqueous medium or liquid material to be treated, with the differential that in the equipment proposed in question, this process is done naturally or spontaneously, ie oxygenation of the material results from the suctioning of the external air by virtue of the negative pressure created in the passage chamber of the equipment. The Venturi effect (also known as Venturi tube) occurs, as it is known, when in a closed system, the fluid in constant motion in a uniform duct is momentarily compressed by finding a zone of narrowing, increasing its velocity and, as it crosses it creates a "low pressure zone".
[005] Associado a este efeito, exatamente na zona de baixa pressão, produz-se diversos furos, dimensionados em diâmetro e quantidade de acordo com o projeto customizado do equipamento - conforme dimensionamento do meio condutor e do respectivo bombeamento ocorrendo o fenómeno de absorção espontânea de gases (ar) graças ao diferencial natural de pressão criado pelo efeito Venturi. Com os gases aspirados dispersos no material conduzido pelo tubo, tudo é conduzido ao final do mesmo, sendo dispensados abruptamente graças ao corte do tubo enquanto estreito, em outro tubo com diâmetro cerca de 50% a maior, criando-se outro efeito, o da turbulência, o que promove oxigenação de todo o material liquido ou pastosamente liquido, tais como efluentes industriais, dejetos orgânicos, cuja oxigenação promove a separação dos materiais sólidos da água. Esta, devidamente oxigenada, deixa de agredir o meio ambiente, renovando a vida aquática ou podendo ser reaproveitada. O dimensionamento do equipamento é feito atendendo as necessidades de cada estação, em face das demandas de vazão real e o tempo de residência do efluente. Com o dimensionamento proporcional à demanda aplicada, ajusta-se a seção menor para o efeito Venturi, de forma a garantir uma
pressão negativa máxima e absorver o máximo de ar, para incorporar o máximo de oxigénio, o qual será dispersado e incorporado no líquido na seção seguinte, por meio de turbilhonamento, onde o escoamento deixa de ser laminar e passa a ser turbulento, simulando a natureza, como suas cachoeiras e corredeiras, "dissolvendo" assim o oxigénio. [005] Associated with this effect, exactly in the low pressure zone, several holes are produced, dimensioned in diameter and quantity according to the customized design of the equipment - according to the dimensioning of the conducting medium and the respective pumping, occurring the spontaneous absorption phenomenon (air) thanks to the natural pressure differential created by the Venturi effect. With the aspirated gases dispersed in the material carried by the tube, everything is carried to the end of it, being abruptly dispensed thanks to the cut of the tube while narrow, in another tube with diameter about 50% greater, creating another effect, that of the turbulence, which promotes oxygenation of all liquid or pasturageally liquid material, such as industrial effluents, organic waste, whose oxygenation promotes the separation of solid materials from water. This, properly oxygenated, stops attacking the environment, renewing aquatic life or can be reused. The sizing of the equipment is done taking into account the needs of each station, in face of the demands of real flow and the residence time of the effluent. With the dimensioning proportional to the applied demand, the smaller section is adjusted for the Venturi effect, in order to guarantee a maximum negative pressure and absorb the maximum air, to incorporate the maximum oxygen, which will be dispersed and incorporated into the liquid in the following section by means of swirling, where the flow stops being laminar and becomes turbulent, simulating the nature , such as its waterfalls and rapids, thus "dissolving" the oxygen.
[006] O mecanismo de transferência do oxigénio para o material que passa pelo duto, se compõe, portanto, de dois efeitos, o já citado efeito Venturi com aspiração dos gases externos ao duto, e o segundo, o de turbilhonamento, por ocorrência de brusco aumento da pressão pela ampliação repentina do duto, resultando, portanto, em pressurização do material em tratamento com difusão e solubilização do oxigénio no mesmo. É de conhecimento que a solubilidade do oxigénio em água tem um comportamento inverso em relação à temperatura (quanto menor a temperatura maior a quantidade de oxigénio dissolvido) e direto em relação à pressão (o aumento da pressão aumenta a quantidade de oxigénio na água). Esse comportamento físico químico é utilizado na concepção do equipamento oxigenador, como o tempo de contato entre as bolhas e o líquido é relativamente curto, é necessário utilizar outras variáveis para conseguir eficiência no processo. Como no caso do equipamento proposto é a área de contato gás/líquido, que cresce com a diminuição do diâmetro e consequente maior número das microbolhas para um mesmo volume de ar, quanto maior a área de contato maior a eficiência na transferência, ficam então associados o aumento de área de contato com o aumento de pressão para gerar o resultado esperado. A alta eficiência de transferência do oxigénio, é decorrente do fato de que no processo de aspiração, devido à alta velocidade do fluido e o tamanho dos orifícios de entrada do ar, são formadas microbolhas que, na fase de pressurização, são comprimidas momentaneamente, aumentando a difusão dos gases no líquido, facilitando assim a solubilização do oxigénio. Outro efeito que se soma a este, é o turbilhonamento gerado na saída pela expansão da área de escoamento, provocando uma segunda fase de mistura ar/líquido, gerando desta forma e
em abundância o oxigénio dissolvido, que mantém a vida da flora e fauna nos rios e lagos. The mechanism of transfer of oxygen to the material passing through the duct, therefore, consists of two effects, the aforementioned Venturi effect with aspiration of the gases external to the duct, and the second, the swirling, by occurrence of abrupt increase in pressure by the sudden expansion of the duct, resulting, therefore, in pressurizing the material under treatment with diffusion and solubilization of the oxygen therein. It is known that the solubility of oxygen in water has an inverse behavior in relation to temperature (the lower the temperature the greater the amount of dissolved oxygen) and direct to the pressure (increasing the pressure increases the amount of oxygen in the water). This chemical physical behavior is used in the design of oxygenator equipment, as the contact time between the bubbles and the liquid is relatively short, it is necessary to use other variables to achieve efficiency in the process. As in the case of the proposed equipment, the area of gas / liquid contact, which grows with the decrease of the diameter and consequent greater number of microbubbles for a same volume of air, the larger the contact area the greater the transfer efficiency, the increase of area of contact with the increase of pressure to generate the expected result. The high oxygen transfer efficiency results from the fact that in the aspiration process, due to the high fluid velocity and the size of the air inlet holes, microbubbles are formed which, in the pressurizing phase, are momentarily compressed, increasing the diffusion of the gases in the liquid, thus facilitating the solubilization of the oxygen. Another effect that is added to this, is the swirling generated at the exit by the expansion of the flow area, causing a second phase of air / liquid mixing, thus generating in abundance the dissolved oxygen, that maintains the life of the flora and fauna in the rivers and lakes.
[007] De forma detalhada, o então pedido de patente de invenção se vislumbra na forma de um equipamento oxigenador que consta de, bomba, responsável pela sucção do líquido para o interior do equipamento, o líquido é encaminhado por tubulação de diâmetro maior até o ponto de estrangulamento, antes contudo, deste ponto, "defletores de rotação", aletas instaladas no interior da tubulação que "quebram" o movimento do fluxo e impedem a formação de vórtices reduzindo o movimento tangencial do líquido, é sabido que, o escoamento rotacional ou vorticoso prejudica o princípio de funcionamento do sistema. Seguindo desta tubulação de diâmetro maior o liquido/material é bruscamente encaminhado para a zona de estrangulamento e, portanto, de menor diâmetro, também conhecida como zona de baixa pressão pois, aproveitando-se para transformá-la em zona de aspiração na qual, orifícios permitem, pelo diferencial de pressão, a entrada do ar "sugado" para que seja incorporado ao meio líquido, seguindo-se então, a zona de pressurização, na qual a pressão do líquido se eleva espontaneamente em zona de turbulência, na qual, intensifica-se a mistura de oxigénio e líquido/material em tratamento, expelindo-se do equipamento então, o líquido totalmente aerado. In detail, the invention application is envisaged in the form of an oxygenator device consisting of a pump responsible for suctioning the liquid into the apparatus, the liquid is conveyed by tubing of a larger diameter to the however, from this point onwards, "rotating deflectors", flaps installed inside the pipe that "break" the movement of the flow and prevent the formation of vortices by reducing the tangential movement of the liquid, it is known that the rotational flow or vortication impairs the operating principle of the system. Following this tubing of larger diameter the liquid / material is abruptly routed to the bottleneck zone and therefore of smaller diameter, also known as low pressure zone since, taking advantage of it to transform it into an aspiration zone in which holes allow the "sucked in" air to enter the liquid medium through the pressure differential, followed by the pressurizing zone in which the liquid pressure spontaneously rises in a zone of turbulence, where it intensifies The mixture of oxygen and liquid / material under treatment is then expelled from the equipment then the fully aerated liquid.
