Abstract

A device for admixing a liquid-state medium to a liquid-state flow, comprising a plate (1) with a certain extension in the thickness direction intended to be connected to a pipe. The plate (1) is provided with openings (2) to bring about a sudden area reduction for the flow flowing in the pipe. The plate further is provided with one or several distribution channels (3) with outlets (4) for the addition of a liquid-state medium. The outlets can be placed on the downstream side or upstream side of the plate, alternatively centrally on the plate.

I en utföringsform utgörs öppningarna av två i vertikalled långsmala öppningar. Uppfinningen kan även utformas med en eller flera långsmala öppningar för att åstadkomma den plötsliga areaminskningen. I utföringsformen med långsmala öppningar är dessa med fördel anordnade så att hela rörets, till vilket plattan ansluts, diameter utnyttjas. Öppningarna kan dock ha olika geometrisk form och dimensioner. Exempelvis kan plattan vara försedd med en U-formad öppning. Den totala öppna arean dimensioneras beroende på hur stort flöde som skall passera blandningsanordningen. tillräckligt högt En avvägning görs där mellan att ha tryckfall att blandningseffektivitet och samtidigt ha en rimlig pumpkapacitet. för säkerställa en god Plattan försedd åtminstone distributionskanal försedd med utlopp för tillförsel av det är vidare med en vätskeformiga medium som skall blandas med vätskan som strömmar i rörledningen. Genom att tillsätta den vätska som ska inblandas i huvudströmmen i ett område med turbulent flöde säkerställs en god blandningseffektivitet. Kemikalier som skall inblandas kan tillsättas på plattans uppströmssida, mitt i blandningsplattan eller på blandningsplattans nedströmssida. Med tillsatsposition menas i. detta fall att utloppen. från distributionskanalen mynnar antingen på plattans nedströms- eller uppströmssida alternativt i de öppningar som anordnats för att åstadkomma den plötsliga areaminskningen. Företrädesvis tillsätts kemikalierna på plattans nedströmssida där trycket är lägre.

The openings in the plate cause a sudden decrease in the area of the pipe, which creates turbulent flow in the liquid flowing in the pipeline. In one embodiment, the openings consist of two vertically narrow openings. The invention may also be formed with one or more elongate apertures to effect the sudden decrease in area. In the embodiment with elongate openings, these are advantageously arranged so that the entire diameter of the pipe to which the plate is connected is utilized. However, the openings can have different geometric shapes and dimensions. For example, the plate may be provided with a U-shaped opening. The total open area is dimensioned depending on how much flow is to pass through the mixing device. high enough A balance is made there between having a pressure drop to mixing efficiency and at the same time having a reasonable pumping capacity. to ensure a good The plate provided with at least a distribution channel provided with an outlet for supplying it is further with a liquid medium to be mixed with the liquid flowing in the pipeline. By adding the liquid to be mixed into the main stream in an area with turbulent flow, a good mixing efficiency is ensured. Chemicals to be mixed can be added on the upstream side of the plate, in the middle of the mixing plate or on the downstream side of the mixing plate. By additional position is meant in this case the outlets. from the distribution channel opens either on the downstream or upstream side of the plate or alternatively in the openings provided to effect the sudden decrease in area. Preferably the chemicals are added on the downstream side of the plate where the pressure is lower. The largest on the downstream side, which means that the chemicals can be added where part of the turbulent zone is located, the pressure of the plate is lowest with good mixing efficiency.

Utloppen kan vara utformade att utgöras av till det tillsatskemikaliens flödesstorlek. Utloppen kan även utformas cirkulära hål. Hàlens diameter anpassas önskade med annan form än cirkulärt tvärsnitt.According to one embodiment, the mixing device is designed so that the pressure drop across the plate is less than 1 bar. According to one embodiment, the distribution channel is designed as a hole with a circular cross-section extending down into the middle of the plate. The outlets can be designed to consist of the flow size of the additive chemical. The outlets can also be designed circular holes. The diameter of the hole is adapted as desired with a shape other than a circular cross-section.

Företrädesvis är distributionskanalens utlopp anordnade med symmetri kring plattans centrum. Uppfinningen skall dock inte begränsas till att utloppen är placerade symmetriskt på plattan utan dessa kan även placeras asymmetriskt.Preferably, the outlet of the distribution channel is arranged with symmetry around the center of the plate. However, the invention should not be limited to the outlets being placed symmetrically on the plate, but these can also be placed asymmetrically.
