Definitions
- the present invention relates generally to a filtration system for the separation of trace gases from the air.
- the invention relates to such a system, which consists of a frameless bellows made of zigzag folded filter material and can be used in addition to an existing filter system in the short term.
- gaseous contaminants to be removed relate to a large number of substances from the family of organic compounds, including those which on the surface do not undergo any chemical reactions, for example with the products or production plants.
- Other examples include basic inorganic or organic substances such as ammonia or amines, acidic inorganic or organic substances such as hydrogen chloride or acetic acid, and sulfur containing compounds such as hydrogen sulfide.
- sorption filter systems and materials have been developed. Their function is always to free the air flowing through as completely as possible of the unwanted admixtures in which these admixtures specific or unspecific bound to sorption materials permanently, while leaving the air with its components nitrogen, oxygen, the noble gases and carbon dioxide unchanged the filter.
- filter solutions are needed that can be installed extremely quickly in addition to the existing filter systems, can be removed for normal conditions, yet provide high performance at high flow rates, can be easily disposed of, take only a small space and in case of emergency prepared to be stored.
- Fig. 1 the expanded filter system according to the invention in a first
- Fig. 2 shows the compressed filter system according to the invention in a first
- FIGS. 3A and 3B schematically show the filter system according to the invention in a second embodiment.
- the additional filter system according to the invention consists of a filter material, which is constructed similar to a blind.
- a Venetian blind is a curtain consisting of band-shaped components (lamellae) which, by means of a suitable device, such as, for example, a cord lift, in the vertical direction can be gathered together (compressed) and pulled apart again (expanded).
- the lamellae are connected to each other by two or more band-like structures.
- the filter system according to the invention (see Fig. 1) consists in a similar manner of a frameless bellows of a zigzag folded (pleated) filter material 2, which is held together or fixed by fixing tapes 4.
- the fixing bands 4 are preferably made of micro-tissue. In a preferred embodiment, fixing bands of 1 cm width are applied at intervals of 30 cm.
- the fixing straps are arranged on both sides of the bellows, preferably in its outer surface area, over the pleat tips and connect them to one another by gluing on the pleat tips. In this way, the entire bellows similar to a blind can be pulled apart and folded.
- Fig. 2 shows the gathered (compressed) filter system according to the invention in a first embodiment.
- the filter design is exactly predetermined by the depth of wrinkles, pleat spacing, material selection and the belt fixation, which means that can be determined by the fixing straps wrinkle spacing and wrinkle position in the expanded position.
- Suitable filter material are foldable sorptive filter media of textile structure based on activated carbons or polymeric sorbents.
- the wrinkle depth is generally in the range of 80-200 mm, preferably 100 mm.
- the pleat spacing is between 14 and 30 mm. A greater depth of wrinkles requires a lower pressure loss and a higher filter efficiency, but at the same time also a greater weight per meter of suspension.
- An essential feature of the filter system according to the invention is that it is an inherently stable and self-supporting frameless filter system which is defined compressible (collapsible) and expandable (fanned), sufficiently stable and can be installed within a very short time.
- the installation is eg. By hanging the filter system (blind filter) in the desired height and subsequent fanning (expanding) of the Bellows reached.
- the filter system After hanging in the vertical direction can then the filter system, which is previously held by a cover in the collapsed state (stockpiling), by releasing the cover like a curtain to fall down (gravity), the filter material 2 by the preset belt fixation 4 automatically the correct distances are set. Subsequently, the filter system can be additionally fixed to the ground.
- the filter system according to the invention is safe from application errors.
- the selected, only small support structure by means of the fixing bands 4 and without another support frame ensures that the filter system according to the invention occupies only a small space, which is particularly advantageous because most ventilation systems offer little additional depth for attaching additional filter systems.
- Another advantage of the filter system according to the invention is the ease of storage, since the frameless, folded filter materials housed in a collapsed (compressed) state to save space and so on stock - may be sealed - can be stored.
- the filter system according to the invention is then ready for use within minutes. If the normal state of the ventilation system is restored, ie, the load on the outside air with additional substances no longer exists, the filter system according to the invention can be easily removed again in order to restore the normal state.
- used filter systems can be easily disposed of, since no elaborate frame structures are available. In this context, the filter systems according to the invention may well have a shorter life without an economically unsustainable situation arises.
- sufficiently low pressure losses in the range of 40-70 Pa can be achieved with high separation efficiency. It is thereby achieved a high spontaneous performance of about 80-95% at high flow velocities of up to 2.5 m / s. By reducing it to a flow velocity of approx. 0.6 m / s, an even higher separation efficiency of up to 97% can be achieved.
- the filter additional system is, for example, arranged on the filter fan unit (FFU) 6 of a fan unit.
- FFU filter fan unit
- the collapsed bellows disposed on a tray holder 6 and provided with a cover 8 ( Figure 3A) is pulled apart after removal of the cover 8 to the appropriate length ( Figure 3B) and mechanically engaged a receiving plate (not shown) fixed.
- a filter additive system with a filter composite of 850 g / m basis weight based on a functionalized chemisorptiven polymer (ion exchanger) was performed.
- the filter composite material was pleated in a fold depth of 90 mm and fixed the predetermined fold position to 900 mm width every 300 mm with 10 mm wide fixing straps on both sides of the pleat pack.
- the prefixed fold position was 20 mm pleat spacing at the respective inlet or outlet opening.
- the system was expanded and suspended at the ends in the ventilation system. At a flow velocity of 2.0 m / s, a pressure drop over the arrangement of 40 Pa occurred.
- the sulfur dioxide (S0 2 ) inlet concentrations into the array were between 4 and 16 ppbv, deposited at more than 88% initial efficiency (separation efficiency). Over the operating period of 10 days, the average power was more than 85%.
- Example 2 Example 2:
- Activated carbon composite material of 800 g / m basis weight based on a microporous chemically surface-modified activated carbon executed.
- the activated carbon composite material was pleated in a fold depth of 90 mm and fixed the predetermined fold position to 900 mm width every 300 mm with 10 mm wide fixation bands on both sides of the pleat package.
- the prefixed fold position was 20 mm pleat spacing at the respective inlet or outlet opening.
- the system was expanded and suspended at the ends in the ventilation system. At a flow velocity of 2.5 m / s, a pressure drop across the arrangement of 78 Pa occurred.
- Hydrogen sulfide (H 2 S) entry levels into the array were between 16 and 43 ppbv, deposited at more than 96% initial power. Over the 14-day period, the average power was more than 85%. Concentrations of sulfur dioxide in the range of 6 - 14 ppbv with more than 95% initial power and an average power of 88% were deposited at the same arrangement and at the same time
- Activated carbon composite material of 750 g / m basis weight based on a microporous chemically surface-modified activated carbon executed.
- the activated carbon composite material was pleated in a fold depth of 90 mm and fixed the predetermined fold position on 560 mm width every 280 mm with 10 mm wide fixation bands on both sides of the pleat package.
- the prefixed pleat position was 14 mm pleat spacing at the respective inlet or outlet opening.
- the system was expanded, placed horizontally in a containment box, and fixed at the ends in pre-stamped tuck-in tabs with both endfolds. At a flow velocity of 0.6 m / s, a pressure drop over the arrangement of 15 Pa occurred.
- Hydrogen sulfide (H 2 S) entry levels into the array were between 10 and 25 ppbv, deposited at greater than 97% initial power. Over the 30-day period of operation, the average power was more than 92%. At the same arrangement and at the same time concentrations of sulfur dioxide in the range of 3-10 ppbv with more than 97% initial power and an average power of 93% deposited. Furthermore, the system was able to separate organic air pollutants with high efficiency. The representative tested component xylene was initially removed more than 97% Efficient at 20 ppbv input concentration, on average over 30 days with more than 90% separation efficiency from the incoming air.
