Pressure relief - flash tank with water seal or membrane for safety devices with biosafety level (bsl) 1 - 2 - 3 and 4 regions

摘要

Pressure relief - flash tank, characterized in that1, a pressure staggering / pressure increase is provided, from p1 to p2, of p2 according to p3,2, a bursting disk and / or a safety valve in the region of p1 with an electric output signal is installed, (1) (2)3, the pressure relief / expansion vessel having a viewing glass, (3) (pipelines - blow-off lines, valves, is calculated and constructed as defined in the pressure devices directive, container volume is calculated on the basis of a risk assessment with the aim of,that biological agents (ba) infectious or not infectious (allergens) are retained securely in the flash tank and this cannot be released into the environment in an uncontrolled manner, thus, the people - and worker protection is reliably ensured,4, the blowing and the introduction of the blowoff line below the liquid level (4) via an immersion tube (4) with holes, drilled holes i.e. sum of the openings is equal to & the surface of the tube cross section and the delivery tube above the liquid level with a vacuum breaker (4) is provided,5, a possibility for cleaning the inner surfaces of the pressure relief - flash tank via cip and sip (5)Connections for the disinfection by means of a disinfectant or a hydrogen peroxide (h gassing₂O₂) can take place,(Cip = cleaning in place) (sip = sterilization in place)6, a precipitate of the steam - air mixture and thus reduction of the pressure in the inner container, reduction of the temperature by means of a water injection means (6) is carried out,7, a bursting disk with electrical output signal in the pressure staggering (7) (1) is installed, these responds when the pressure p2 is exceeded, and that, furthermore, the installation of a demister (demister) with a subsequent sterile filter takes place over the sterile filter is then possible for the blowing off into the environment.8, a pressure relief - flash tank with subsequent systematic structure, (8)calculated and constructed as defined in the pressure devices directive, container volume is calculated on the basis of a risk assessment with the aim of,that biological agents (ba) infectious or not infectious (allergens) are retained securely in the flash tank and this cannot be released into the environment in an uncontrolled manner, thus, the people - and worker protection is reliably ensured,a pressure staggering / pressure increase is provided but9, the pressure relief - flash tank with an elastic diaphragm is divided into two parts, (9)in an optional admission of pressure to all sides, the elastic balloon-shaped membrane ends (9)the membrane temperature, – and is chemically resistant, membranes by means of clamping flange is fixed, the intermediate seal of the two-part container with closely monitoring unit visually or electrically with integration in the plc, (9) ..
