Description

Self-disinfecting odor trap assembly and method of operation

The present invention relates to a self-disinfecting

Odor trap assembly for installation in a sewer pipe. Moreover, the invention also relates to a method for operating such an odor trap assembly. An odor trap is usually a piece of pipe, which holds a certain amount of the inflowing liquid ^¬ ability odor barrier in the pipe system by its shape. All inflowing germs find ideal development conditions in this barrier ^fluid and multiply explosively. The contamina- tion of the barrier fluid increases steadily. additionally

develops on the walls of the tube inside and outside the barrier liquid a highly contaminated biofilm from all existing germs. The existing above the liquid barrier ^¬ ness column of air in the interior of the drain trap is also greatly contaminated by the biofilm. At the

Influence of liquids in such a contaminated odor trap leads to the following problems. On the one hand, an amount of contaminated air equivalent to the volume of the infiltrating liquid is returned to the room from the odor trap at high speed

spun. This leads to a direct recontamination of the room air and the surfaces coming into contact with the contaminated air. Furthermore, the impinging of the inflowing liquid on the surface of the high

contaminated barrier fluid a heavily contaminated

Aerosol that conveys the stagnant air in the trap into the adjacent room. For the disinfection of odor traps, it is known to use the germicidal properties of ultraviolet radiation. Such solutions are shown, inter alia, in DE 42 06 901 AI, in DE 40 25 078 AI and in DE 295 09 210 Ul. The problem here is that disinfection takes place only where the ultraviolet radiation impinges. The system is too slow and only disinfects directly

illuminated areas. Pollution limits the

Effectiveness clearly.

DE 27 47 992 Al and US 3,175,567 show a cleaning and disinfection of siphons using ultrasound. According to US Pat. No. 6,666,966 B1, an anti-adhesion layer is additionally provided in the siphon.

A disinfection can also be done by spraying a disinfectant by means of nozzles. Such solutions are u. a. in DE 92 14 542 Ul and in EP 1 295 585 Bl. In this way, the barrier liquid is disinfected. However, only the directly sprayed

Areas of the odor trap disinfected as the

sprayed disinfectant does not reach all areas of the odor trap. For disinfection, a large amount of concentrated disinfectant is needed, which is both expensive and environmentally disadvantageous.

Furthermore, there are solutions that a thermal

Disinfect the odor trap. Such solutions are u. a. in EP 1 159 493 A1, in

DE 42 06 901 AI and shown in US 4,192,988. Thus, it is known, for example, to automatically start a heating process with each run-in of liquids. Disadvantageous This solution is the high power consumption and the great technical effort to prevent calcifications of

System. In addition, there are time ranges, which range from the inflow of new fluids to the achievement of the killing

Temperatures last in which contaminated aerosol can form. The maintenance is relatively high.

By installing a splash guard with targeted guidance of the liquid flowing into the odor trap, a formation of contaminated aerosol can be suppressed. Since no disinfection takes place in this system, there is a risk of microbial contamination, which means frequent replacement

contaminated system components required. EP 0 514 636 A2 describes a method for the vapor deposition of rooms or thermal disinfection of surfaces, in particular of closed spaces through which it is possible to flow. The process utilizes a heated, nebula-type medium, which is passed as a flow through the rooms to be disinfected. A heated stream of air or gas is generated in which either steam or an aerosol of water and a disinfectant is introduced. The nebular medium is applied to the surfaces to be disinfected with slight overpressure. To carry out the method described is a device which comprises a connected to a supply line housing. The housing communicates with a fan. Within the housing, a heater for heating forced air is arranged. A spray device for generating fine liquid droplets opens into the housing in the region of

Heating device. AT 391 934 B shows a degermination device for air ducts, pipes and the like. ä. A disinfectant is atomized by an ultrasonic ^¬ nebulizer in the smallest aerosols to 0.3 ym and out ^¬ with the aid of a blower to the sites to be sterilized. The finely atomized disinfectant sweeps the surfaces to be sterilized and condenses, since the surface temperature of the channels is below the dew point of the air sterilization ^mixture . For this purpose, the air sucked in by the fan is heated by an air heater to about 35 ° C. The sewer sections to be sanitized can be shut off with shut-off devices. About a pressure relief valve, the air-sterilization mixture is supplied through flexible lines or hoses via a connection to the degermination unit and further enriched with the sterilization ^¬ medium in the ultrasonic nebulizer and kept in circulation until the required concentration in

Channel is reached.

From WO 00/53857 Al a self-disinfecting odor trap is known. The arrangement described therein comprises a conventional odor trap with a therein

contained sealing liquid, a public address and

Oscillation system of any frequency and a system for heating the interior of the odor trap. The interaction of both systems is controlled by an appropriate regulation so that during use a cleaning and

Disinfection of the odor trap can be ensured. However, this solution is relatively expensive;

both in the realization, as well as in the later operation. The object of the present invention is thus to provide a self-disinfecting odor trap assembly, which enables automatic and permanent disinfection during operation, wherein the Disinfection a relatively small amount of disinfectant ^¬ should be required. The trap should be simple in design, be cause the least possible cost operation ^¬ and maintain with little effort. Furthermore, a method for operating such a

Odor trap assembly can be provided.

To solve the object of the invention serve a self-disinfecting odor trap assembly according to the

attached claim 1 and a method according to the

attached independent claim 11.

The inventive self-disinfecting odor trap ^¬ arrangement is provided for installation in a sewer. The sewer line is used for discharging non-permanently flowing wastewater from a room to the outside

Space. The odor trap assembly prevents

Odors from the sewer pipe enter the room; even in those periods in which no wastewater flows. The room is preferably one

Room to be placed on the increased hygienic requirements, for example, a room in a hospital, such as in an operating room. The odor trap assembly comprises a first

Odor trap with a designed as a downpipe first pipe section. The property of the first

Pipe section as a downpipe is given by the fact that the first pipe section is arranged vertically or at least predominantly vertically, so that the inflowing wastewater within the first pipe section due to its

Gravity can fall down and flow. The first pipe section has on the input side a spout connection Inflow of sewage up. The spout connection forms the input for the waste water to flow into the

Trap arrangement. The odor trap further comprises a to the first pipe section in

Flow direction of the wastewater subsequent wastewater dissipating second pipe section. The second pipe section thus serves to supply the waste water in the subsequent sewer line. The odor trap assembly further includes a

Vernebier for producing a disinfecting agent mist. With the help of the Vernebiers a disinfecting agent is converted into the disinfecting agent mist. In which

Active agent mist is an aerosol in which the liquid particles of the active ingredient are dispersed in air. Another component of the odor trap assembly is one between the nebulizer and the first pipe section

arranged connecting line for supplying the active substance mist in the odor trap. Accordingly, the active substance mist produced in the nebuliser flows from the nebulizer through the connecting line into the

Trap. The connection line opens in particular into the first tube section of the odor trap, so that the deliverable active agent mist exits in the first tube section and distributes itself there. The connection line opens

preferably laterally in the first pipe section of

Odor trap.

The second pipe section can be closed by an odor-occlusive blocking means, whereby the function of the

Odor trap assembly is effected as an odor trap. The blocking agent prevents odors, ie gases against the flow direction of the waste water from the sewer line back get into the room. However, the blocking means allows one

Flow of the waste water in the flow direction for draining the wastewater. According to the invention the blocking means forms a spatial

Limitation for the feeding into the odor trap

Drug mist. The blocking means forms in particular a lower boundary for the in the first pipe section

Due to its gravity, this can build up as a standing active substance nebula column in the first pipe section. The active substance nebula column is under the prevailing air pressure in the room and therefore not under an increased pressure. The active ingredient nebula column is due to their weight. The drug mist is heavier than air. The disinfecting effect of

Active substance nebula column occurs in particular during those periods in which no wastewater flows. These temporal sections occur during the

Proper use of the odor trap assembly, so there is no interruption of this intended

Use by special measures for disinfection needs. The standing active nebula column is thus during the

intended use of the odor trap assembly buildable. The standing active substance mist column is preferably based on that in the second in the first tube section

Pipe section located blocking means up to the

Discharge connection buildable.

The flow of the inflowing wastewater is not hindered by the blocking agent. Thus, the barrier agent is permeable to sewage. The odor-occlusive effect and the wastewater permeability of the barrier agent are preferred permanently given, so that it requires no actuator for the locking means.

A significant advantage of the invention

Self-disinfecting odor trap assembly can be seen in the fact that the disinfecting agent mist produced with the remote Vernebier has a very large effective surface, resulting in a high cleaning and disinfecting effect

is ensured. Through the blocking means is a

Limitation of the pipe section to be cleaned, so that a standing active nebula column can arise. The standing active nebula prevents a germinated column of air in this area. By condensation of the active agent mist on the adjacent inner walls of the odor trap they are also disinfected and cleaned. That at the inflow of

Liquid in the odor trap resulting contaminated aerosol is when passing through the active agent mist

disinfected. According to the invention, the recontamination of room air and surfaces outside the odor trap can be reliably prevented. The self-disinfecting

Odor trap assembly is therefore also suitable for use in highly sensitive areas where particularly high hygiene requirements prevail. For disinfection is only one

comparatively small amount of disinfectant required, whereby the environment is less burdened and not least, costs can be saved.

The odor trap assembly is preferably suitable for installation in the sewer line described. The effluent may be, for example, the waste water produced during a purification or emptying of the human body, but also special types of waste water, such as for example, from medical devices, such as dialysis machines act.

The spout connection is preferred as a spout of a

Sink, a bathtub, a shower tray, one

Urinais, a toilet or even a medical device trained.

The vernier is preferably an ultrasonic nebulizer. By ultrasonic nebulization droplet sizes below 10 ym can be generated. Droplet sizes of 4 ym to 5 ym have been found to be particularly favorable. It should not be

Restriction to ultrasonic nebulizer done. The used Vernebier should preferably the production of

Allow droplet sizes below 10 ym. To ensure a continuous supply of the nebulizer with a disinfectant which forms the active ingredient, the nebulizer is preferably connected to a disinfectant reservoir so that the disinfectant can flow from the disinfectant reservoir to the nebulizer.

For use in highly sensitive areas with correspondingly high hygiene requirements, it is expedient to equip the odor trap assembly with a second Vernebier, which is available for a malfunction of the first Vernebiers without delay for nebulization.

In an advantageous embodiment, the second

Pipe section formed as a siphon to receive the blocking means in the form of a barrier liquid formed by a portion of the waste water. The siphon is preferably U-shaped, so it preferably by a tube siphon is formed. Alternatively, the siphon is preferred by a bottle siphon, by a cup siphon, by a

Double tongue siphon or formed by a flush siphon. On the inner walls of the siphon condensing drug mist enters the barrier fluid and provides for their

Disinfection. The active ingredient nebula column is on the

Sealing liquid. The barrier liquid forms the lower spatial limit for the active ingredient nebula column. The odor trap arrangement is preferred with a second

Connecting line for the supply of a part of

Active agent mist equipped in the odor trap, which is arranged between the Vernebier and a subsequent in the flow direction behind the siphon formed as the second pipe section third pipe section.

Accordingly, part of the active agent mist produced by the vaporizer flows from the nebulizer through the second

Connecting line through to the third pipe section. The third pipe section preferably extends in the horizontal direction. By introducing the part of the generated active substance mist in the flow direction behind the siphon and this area of the odor trap assembly is disinfected. This can be an intrusion of

Microorganisms are prevented from the underlying pipe system in the barrier liquid. The condensing on the inner walls of the third tube section aerosol flows into the barrier liquid, and thus also increases the effective ^¬ concentration in the barrier fluid. An alternative preferred embodiment used as

Blocking means at least one in the second pipe section

arranged flap, which can also be designed as a valve as another mechanical shut-off device. The Flap, the valve or the mechanical shut-off device forms a further component of the odor trap assembly. The flap is closed when no sewage in the

Odor trap flows. As a result, a contaminated aerosol only in the second pipe section in the flow direction behind the flap arise. In this way, it hardly can

Return contamination come. The flap is preferably designed such that it automatically closes due to its weight, for example by being mounted at its upper end. The flap can also be formed by a rubber flap. The flap, the valve or the mechanical shut-off device can also be urged by a spring in the closed state. The flap, the valve or the mechanical shut-off device is preferably designed such that it opens by the pressure of the inflowing from the first pipe section wastewater. The second pipe section preferably has a shape in which the flow direction continuously changes from the vertical direction to the horizontal direction, wherein the leakage in the horizontal direction by an elongated spout

is extended and the flap, the valve or the mechanical shut-off device in or in the flow direction behind the extended spout is. In any case, the second pipe section is preferably shaped such that through this the kinetic energy of the incoming,

falling wastewater gradually and gently, d. H. is continuously reduced while the flow direction of the waste water is transferred in the horizontal direction, whereby the

Formation of splashing is greatly reduced. For this purpose, the second pipe section is preferably

Sprungschanzenauslaufförmig trained. The described shape has the great advantage that the splash water that usually forms during the inflow of waste water is significantly minimized can be, thereby minimizing the formation of

contaminated aerosol is feasible.

The odor trap assembly according to an advantageous embodiment comprises a control unit for controlling the

Supply of active substance mist into the odor trap.

Using the control unit, both the generated

Active substance mist amount and the discharge pressure of the Vernebier be regulated. So can the amount of active ingredient

For example, be set so that above the

Barrier always a permanent active ingredient nebula column

is maintained. The control can preferably also ensure that a portion of the active agent mist condenses on the inner walls of the odor trap by appropriate metering of the active agent mist. This will get a part of the

Active substance and impurities in the barrier liquid or in the area behind the flap, there too for a

Disinfection and biofilms and odors counteract. By means of the control unit may preferably

Application rate, discharge rate and timing of the

Drug mists are regulated. In addition, the serves

Control unit preferably to malfunction of

To detect odor trap assembly and corresponding

To generate warning signals. With the control unit and the level of the disinfectant storage can be monitored to always have a sufficient amount of disinfectant available. The generated warning signals can via known transmission systems, such as WLAN, LAN or

Bluetooth, to which the responsible maintenance personnel are transferred.

In an expedient embodiment, the spout connection comprises a splash guard for preventing from the first Pipe section of re-injected wastewater. The splash guard is preferably designed to reduce the flow rate of the inflowing wastewater. Furthermore, it has proven to be advantageous to mold the splash guard such that it causes a deflection of the flow direction of the inflowing wastewater, in particular from a vertical direction in a horizontal direction. The splash guard can as a

automatically closing membrane or be designed as an automatically closing lamellar closure. The membrane preferably has a circular cross section whose

Outside edge sealingly abuts the inner wall of the first pipe section in the closed state. When inflowing sewage, the membrane opens and gives a

Flow channel for the wastewater free. In the periods in which no wastewater flows, the membrane is against

closed and prevents the air exchange between

Odor trap and room air. The lamellar closure preferably comprises a plurality of lamellae which extend radially from a central stop or holding element in the direction of

Inner wall of the first pipe section or vice versa extend.

The central stop or holding element extends in the longitudinal direction of the first pipe section. In the closed state, the lamellae seal against the central stop element or on the inner wall. When inflowing wastewater, the lamellae remove from the central stop element or from the inner wall and release a flow channel. In alternatively preferred embodiments, the splash guard is formed by a spout extension with lateral openings, which projects into the first pipe section. The

Spout extension preferably has the outer shape of a

Cylinder whose outer diameter is smaller than the

Inner diameter of the first pipe section is. The cylinder is closed on its underside. The lateral ones

Openings are in the cylinder jacket.

The connecting line between the Vernebier and the first pipe section is expediently as a pipe or as a

Hose executed. It is preferably at least 10 cm long.

The possibly existing second connecting line between the nebulizer and the third pipe section is expediently designed as a pipe or as a hose. she is

preferably at least 10 cm long.

It is advantageous to equip the Vernebier with an air supply for supplying room air, which is not from the

Odor trap assembly comes. The air that can be supplied by the air supply forms the carrier of the active substance mist.

The odor trap assembly preferably further includes a fan for transporting the active agent mist from the vernier into the odor trap. The fan can be in the

Connecting line or before the connection line on

Vernebier be arranged. In the embodiments which have a second connecting line for feeding a part of the active agent mist into the third pipe section, is also preferably in the second connecting line

The odor trap can be made of any material, which, however, should be resistant to the disinfectant used. The material used preferably prevents or impedes the adhesion of

Dirt and microorganisms. Alternatively or additionally, the inner wall of the odor trap with a Adhesion of dirt and microorganisms preventive or aggravating coating be provided, which is very smooth. In addition, an additional germ-inhibiting or germicidal coating of the inner wall has proven to be preferred.

The odor trap arrangement expediently comprises an electric accumulator which controls the operation of the

Odor trap assembly even with a power failure over a certain period of preferably at least

ensures three hours. As a result, disinfection is also possible at locations where no power connection is available. The inventive method is used to operate the self-disinfecting invention

Odor trap assembly and includes the following steps.

First, a drug mist by operating the

Vernebiers generated. Subsequently, the generated active substance mist is supplied via the connecting line into the first tube section of the odor trap, whereby a standing active substance mist column consisting of the supplied active substance is built up over the blocking means. By supplying and introducing the generated active substance mist via the connecting line into the first tube section of the

Odor trap will prevent that there

Contaminated gas or contaminated aerosol is formed.

The method according to the invention preferably serves for operating preferred embodiments of the self-disinfecting odor trap arrangement according to the invention. Preferably, the method also has such features associated with with the self-disinfecting invention

Odor trap assembly are specified.

The standing active substance mist column is preferably produced and maintained in the first pipe section, based on the blocking means located in the second pipe section, up to the spout connection. As a result, a recontamination of the room air is reliably prevented. The standing active substance mist column is preferably maintained permanently and completely insofar as waste water, which flows into the first pipe section through the spout connection, permits this. After the inflow of effluent into the spout port has been completed and the effluent has been completely drained through the first section of pipe, the standing aerosol mist column is preferably completed again to completely feed the first section of pipe over the barrier means

Fill in drug mist.

The nebuliser is preferably fed to the nebulization of an active ingredient, which by an aqueous solution of

Hydrogen peroxide and at least one carboxylic acid is formed. Alternatively or in addition to the carboxylic acid, one or more silver salts can also be used. The active substance is highly effective in the lowest concentration of the aqueous solution of preferably less than 10%. To prove the efficacy of

This substance should be in the disinfectant list of the Association for Applied Hygiene (VAH) or in the

List of disinfectants of the German Veterinary Society (DVG). The amount of active substance introduced into the odor trap must be so low that, when the total amount of active substance leaves the cavity of the odor trap, all relevant limit values with regard to the individual components of human health are obtained remain well below. According to an advantageous embodiment, the active substance is biodegradable and comprises 80% to 95% pure water, 2% to 12%

Hydrogen peroxide and 2% to 10% of one or more

Carboxylic acids, wherein the carboxylic acid is preferably by

1 shows a simplified representation of a fiction, ^¬ self-disinfecting odor trap assembly oil in a first embodiment, which is particularly for a pool in an operating room. The odor trap assembly according to the invention Ol first comprises a

Odor trap 02. The odor trap 02 has a first pipe section 03 designed as a downpipe. The first pipe section 03 has on the input side a spout connection 04, in which wastewater can flow. The first

Pipe section 03 joins in the flow direction a

Wastewater dissipating second pipe section 05 at. The second pipe section 05 is formed in the embodiment shown as a U-shaped siphon. Due to the U-shaped shape of the second tube section 05 remains a part of the inflowing The barrier liquid 07 serves as an odor-occlusive blocking means and limits the volume in the first pipe section 03. The second pipe section 05 is adjoined by a third pipe section 08, which extends in the horizontal direction. On the output side, the third pipe section 05 ends in a drain connection 09, via which the wastewater can flow into a connected drainage system (not shown). The odor trap 02 expediently consists of a material which prevents or at least impedes the adhesion of dirt and ^{microorganisms} . Alternatively or additionally, the inner wall of the odor trap 02 may also be provided with a coating which prevents the adhesion of dirt and microorganisms or aggravates it. In addition, the inner wall can be a germ-inhibiting or

have germicidal coating.

The odor trap assembly 01 further comprises a nebuliser 10 for producing a disinfectant active agent mist. The nebulizer 10 is preferably an ultrasonic nebulizer, with which droplet sizes below 10 ym can be generated. A continuous supply of the Vernebiers 10 with the disinfectant to be atomized as an active ingredient preferably takes place via a connected to the Vernebier 10

Disinfectant storage (not shown). When

Disinfectant has a biodegradable mixture with the constituents 80% to 95% water, 2% to 12%

Hydrogen peroxide and 2% to 10% carboxylic acid proved to be favorable. The nebulizer 10 is connected via a connecting line 12 to the first pipe section 03. The

Connecting line 12 serves to supply the active substance mist generated in the vernier 10 into the odor trap 02. It is designed as a tube or as a hose. For transport the active substance mist from the Vernebier 10 in the first

Pipe section 03 is a fan (not shown). The fan may be arranged in the connecting line 12 or in front of the connecting line 12 at the Vernebier 10.

To control the supply of active substance mist into the odor trap 02, a control unit (not shown) is preferably used, which forms a further component of the odor ^closure arrangement 01. About the control unit, the application rate, the application pressure and the timing of the im

Vernebiers 10 generated drug mists are regulated.

In addition, the control unit can also monitor the proper operation of the odor trap assembly 02 and generate corresponding warning signals in case of malfunction. The warning signals may be transmitted via known transmission systems to external dispensing and processing systems to alert the appropriate service personnel. The control ^¬ unit can also monitor the level of the disinfectant ^¬ memory to timely refilling the

Active substance mist column 11 can be permanently guaranteed or generated at fixed time intervals. The

Service life of the active ingredient nebula column 11 is at the

Contamination level of the room to be disinfected in the odor trap 02 adaptable. Condensing active agent mist flows down due to gravity on the inner wall down to the barrier liquid 07, where the active ingredient also has a disinfecting effect. Due to the existing active ingredient Nebelsäule 11 in the described range, penetration of air and their contamination is effectively prevented.

Flow direction behind the designed as a siphon second pipe section 05 and connects the Vernebier 10 with the third pipe section 08. By introduced in the flow direction behind the second pipe section 05 drug mist also this area is disinfected. This way you can

prevents contamination from the underlying pipe system in the barrier liquid 07 arrive.

It also condenses on the inner wall of the third

Tube section 08 drug mist and flows into the barrier liquid ^¬ 07, so that the concentration of active ingredient in the barrier fluid 07 additionally increased.

Fig. 3 shows a partial view of the self disinfecting air trap ^¬ arrangement 01 according to the invention in a third embodiment. In this embodiment, the second pipe section 05 is jump-jump shaped

educated. Through this shaping, the

Flow rate of the odor trap 02

introduced wastewater can be reduced. The

Splash formation is thus also significantly reduced, so that the formation of contaminated aerosol can be minimized. Unlike the ones described so far

Embodiments serves as a blocking means one in the second

Pipe section 05 arranged flap 14, which closes automatically due to their weight. As Non-return flap executed flap 14 is closed when no wastewater flows into the odor trap 02. Thus, a contaminated aerosol is formed only in the second

Pipe section 05 in the flow direction behind the flap 14, whereby recontamination is virtually eliminated.

The flap 14 is used instead of the sealing water 07 (shown in Fig. 1) as a mechanical lock on which the
