Description

Technical field

The invention relates to the integrated system for disinfection, dedusting and decontamination with very fine non-condensable aerosol mist. The present invention also relates to the hydraulic nozzle of such system. The invention generally falls within the fields of healthcare and military.

Background

Healthcare, military as well as other government institutions face serious problems related to electrostatic discharge (ESD), unsettled dust, microbiological contamination and challenging disinfection conditions. These problems are eliminated by aerosol disinfection, humidification systems. One such system is the system using pneumatic nozzles, which usually depend on compressed air supplied by the compressor as described, for example, in utility model SK 9591 Y1. Such systems have several disadvantages: not only do they increase operating costs, but they also complicate implementation in field conditions and require regular maintenance. Pneumatic nozzles must be supplied with a stable air flow to ensure proper operation, which leads to additional operating costs for compressor servicing and energy consumption.
Other aerosol disinfection, humidification systems are hydraulic systems without the use of the compressor, where the high pressure pump extracts the liquid from the tank and pushes it into the nozzle system, which does not ensure accurate and efficient distribution of the disinfecting aerosol into the nozzles without the use of additional precision regulating and controlling hydraulic and electronic components, as documented, for example, by the utility model SK 9561 Y1. The main problem with existing systems is their instability.
The shortcomings of the existing devices known in the state of the art evoked the need for developing affordable and efficient solutions providing accurate and effective distribution of disinfectant aerosol to the nozzles. The effort to create such device with the aforementioned requirements resulted in the integrated aerosol mist disinfection, dedusting and decontamination system according to the present invention comprising the hydraulic nozzle for dry mist generation, which would produce dry mist with high efficiency over the entire range of operation.

Summary of the invention

The integrated aerosol mist disinfection, dedusting and decontamination system according to the present invention has been designed to perform three basic functions: disinfection, dedusting and decontamination. These functions are designed to contribute synergistically to the improvement of hygiene and safety conditions in the armed forces and their operating areas, as well as in field stations.
The essence of the present invention is that the system comprises the tank generally for liquid, which is, for example, disinfecting solution, wherein the auxiliary pump is connected to the tank with the liquid output pressure in the order of units of bar. The auxiliary pump is connected through the filter to the high pressure pump with the liquid output pressure on the order of tens of bar. The output of the high pressure pump is connected by at least one pipe to hydraulic nozzles for efficient distribution of the liquid or disinfecting solution. The ceramic-tipped hydraulic nozzles according to the present invention (hereafter also referred to herein as "hydraulic nozzles" or simply "nozzles" for short) generate very fine non-condensable aerosol mist.
The auxiliary pump is electrically connected to the control unit. In the electrical branch between the auxiliary pump and the control unit, electrical distribution components such as circuit breakers are included. The control unit together with the high-pressure pump forms one basic functional unit, which is the key component to ensure accurate and efficient distribution of the liquid into the ceramic nozzles. If the integrated system contains multiple nozzle sections, then the output of the high-pressure pump is connected to the ceramic nozzles with multiple pipes through the section controllers. From the safety point of view, it is suitable if the pressure relief valve is included in the outlet piping.
The design and final form of the system are tailored to the specific requirements and configurations of the given spaces, ensuring that each system is unique and autonomous. This approach allows the performance and adaptability of the system to be optimised in different applications. The automation of the system ensures its efficient and trouble-free operation and is implemented by the use of the switching hydraulic solenoid and Blow off valve.
The disinfecting solution or water is fed into the tank, which serves as the storage tank and liquid volume regulator. The tank is equipped with efficient filters that remove mechanical impurities and ensure that only clean, contaminant-free liquids enter into the hydraulic system. Nozzles are strategically placed to ensure aerosol is dispersed evenly and efficiently throughout the space. By creating of the fine aerosol mist, the surface area of the disinfecting solution is increased, which maximizes its effectiveness in interacting with pathogens and contaminants in the environment. In this way, the system ensures not only efficient disinfection processes, but also rapid and uniform application of the solution. The stainless steel piping, ceramic nozzles and tank are made of chemically resistant materials that are able to withstand the aggressive chemical components of disinfecting solutions. This ensures the long lifetime of these components and minimises the risk of degradation that could lead to system failures. The chemical resistance of the materials ensures that the system will function reliably even in long-term use.
The advantages of the integrated aerosol mist disinfection, dedusting and decontamination system according to the present invention are apparent from the effects thereof, which are manifested externally. The effects lie in the use wherein the system is thoughtfully designed to ensure the effective application of disinfecting solutions, thereby contributing to maximum efficiency in destroying pathogenic microorganisms and ensuring hygienic conditions, which is the key for maintaining the microbiological safety and preventing the spread of infections.
This integrated system is fully automated, allowing precise control and monitoring of all processes, including pressure control, flow and disinfecting solution distribution. This automation ensures not only high efficiency but also consistency in application, thereby reducing the risk of human error.
The important aspect of the present invention is also its modularity, which allows the system to be adapted to different requirements and environmental conditions, whether for stationary installations in medical facilities or applications on military bases. Together, these factors contribute to the higher standard of hygiene and safety in critical operational environments. More efficient disinfection systems have been developed that provide easier installation and maintenance, while being less costly and more stable. Due to its modular design, the system according to the present invention provides the flexibility in expanding and adapting to the needs of different operations. The addition of further autonomous control modules allows the pump capacity and the number of ceramic nozzles to be increased without a significant increase in cost, thus ensuring economic efficiency. One of the significant advantages of the system is its ease of installation and calibration, which does not require major modifications to the existing infrastructure. This aspect ensures fast and efficient implementation, which is particularly important in situations where an immediate response is required.
The key element is the high-pressure pump, which ensures precise and efficient distribution of the disinfecting aerosol. The high-pressure pump also provides robust and consistent liquid distribution without the need for expensive pneumatic equipment. In this way, it enables precise pressure control, which is essential for the generation of homogeneous aerosol, and thus increases the efficiency of the application of disinfecting solutions.
Compared to piston (reciprocating) or screw compressors, the maintenance of the high pressure pump is significantly easier and less frequent, resulting in reduced operating costs and minimizing the risk of leakage of compressor oil into the environment. This innovative approach not only guarantees technical efficiency, but also improves safety conditions during system operation, enhancing overall efficiency in the areas of disinfection, decontamination and dedusting. Current existing solutions are not sufficiently responsive to the upcoming needs for development and improvement, and it is therefore necessary to invest in upgrading the technology with regard to efficiency and sustainability.
This system effectively increases the humidity in the operating areas, which contributes to a substantial reduction in the risk associated with electrostatic discharge (ESD). Electrostatic charge can cause unwanted sparking, which is potentially dangerous, especially in environments where flammable and explosive substances and fine dust particles are present. Creating the optimum humidity conditions helps counter these risks. The system can reduce dust in the environment by 85 to 90%, thereby creating healthier and safer working conditions for personnel and increasing protection of devices. Such decrease in dust not only minimises the risk of respiratory diseases, but also prevents the destruction of sensitive technological devices and, most importantly, the potential for dangerous explosions during the storage and handling of ammunition or explosives.
The system also provides the option of high-pressure cleaning and rinsing, making it a multifunctional tool for various applications. In addition, the system contributes to the regulation of the air temperature in the working environment, which is particularly useful in hot and unventilated areas, thus increasing the comfort of the workers.
The ceramic-tipped hydraulic nozzles used in the present invention play essential roles in the spraying process, as they are able to create a homogeneous aerosol dispersion that reaches even hard-to-reach areas. This is achieved thanks to its head, which enables the hydraulic nozzle to produce a dry mist with much higher production than nozzles known in the state of the art are capable of and ensures that the diameter of the dry mist particles is maximally 10 µm. Such a hydraulic nozzle head for dry fog generation with a ceramic tip and a body equipped with an external thread and a manipulation hexagon includes the external hollow cylindrical head body made of plastic, the face of which has the internal flange. The ceramic tip having the spherical cap and the jet orifice at its centre is arranged in the face of the outer hollow cylindrical head body. The jet orifice has the inner diameter ϕ₂ and the outer diameter ϕ₁, which is preferably between 140 µm and 160 µm preferably with the taper ratio 1:8 to 1:12. With thus chosen jet orifice diameters and taper ratio, the atomizing integrity and uniformity of the individual droplets is maximized as well as extending the lifetime of the tip.
The ceramic tip has the outer rim that adheres to the inner flange of the outer hollow cylindrical body, and they are still glued together. The ceramic tip has a truncated cone-shaped open cavity on one side with at least two flow outlet channels arranged in the conical surface of the open cavity continuing to the face of the open cavity. The flow-through outlet channels are terminated by the outlet orifice that leads into the cavity of the jet orifice. The flow outlet channels in the conical surface of the open cavity and in the face of the open cavity of the ceramic tip are preferably flat and are preferably shaped like an inequilateral triangle, wherein the base of the inequilateral triangle is located on the outer rim of the ceramic tip and the vertex of the inequilateral triangle opposite the base is located on the inner diameter ϕ₂ of the jet orifice. The alternative solution is also possible, wherein the flow outlet channels in the conical surface of the open cavity and in the face of the open cavity of the ceramic tip are flat and have the shape of an equilateral triangle. It is the use of triangular shaped flow outlet channels that maximises the atomizing quality, as confirmed in the tests.
The hydraulic nozzle head further comprises the inner hollow cylindrical body with the partition in which the central bridging orifice is provided. The partition on one side of the inner hollow cylindrical body defines the space of the inlet chamber. The partition on the other side of the inner hollow cylindrical body defines the outlet chamber space. In the outlet chamber, axial partitions are arranged around the inner periphery of the outlet chamber, which between them define inlet flow channels for the discharge of the liquid. The inlet flow channels provide for increased liquid flow through the hollow cylindrical body, since the diameter of the movable piston is also substantially smaller than the inner diameter of the inner hollow cylindrical body. Preferably, the inner hollow cylindrical body is inserted in the outer hollow cylindrical body so that over the first rubber or silicone seal it abuts against the outer rim of the ceramic tip. The use of the first seal, in addition to sealing, also allows the protection of ceramic tip, which is fragile, against stresses arising, for example, during the assembly or disassembly of the tip.
The truncated cone-shaped plug and the movable piston are disposed in the outlet chamber, the spring being fitted with one end on the piston and the other end inserted into the cylindrical recess in the plug. The plug thus permanently abuts its face against the face of the open cavity in the ceramic tip. The movable piston in the idle position abuts against the partition and overlaps the central bridging orifice. After the pressure liquid is supplied into the inlet chamber of the inner hollow cylindrical body, the pressure of the fluid is greater than the spring preload and the piston uncovers the bridging orifice. The spring preload is controlled by the working pressure of the liquid and also ensures the removal of foggy particles substantially larger than 10 µm at the beginning of the work when the liquid is supplied to the nozzle. In this way, the fed liquid is passed through the inlet flow channels and the outlet flow channels to the jet orifice in the ceramic tip.
According to the present invention, the hydraulic nozzle comprises the hydraulic nozzle head for formation a dry fog described above and further comprises the body having the shape of a truncated pyramid with the internal shaped cavity, wherein the flat face of the body has the threaded mounting orifice into which the hydraulic nozzle head is screwed. The hydraulic nozzle further comprises the flange having the recessed semi-cylinder shape, which is movably inserted into the body, the flange having the entry orifice for the needle. The hydraulic nozzle further comprises the second seal that is in contact among the hydraulic nozzle head, the inner hollow cylindrical body and the flange. The hydraulic nozzle further comprises the needle inserted into the inlet orifice having the inner diameter preferably in the range of 1,85 mm to 1,95 mm. The inner diameter in this range provides sufficient liquid supply at a given working pressure to prevent possible clogging, while at the same time providing sufficient resistance of the needle. The hydraulic nozzle further comprises the filter inserted into the inlet chamber. The hydraulic nozzle further comprises the clip which surrounds the truncated pyramid-shaped body to form a compact hydraulic nozzle assembly.
The advantages of the construction of the hydraulic nozzle head for formation a dry fog and the hydraulic nozzle of the disinfection device for formation a dry fog according to the invention, compared to solutions known in the prior art, are apparent from their construction. The significant advantage of the solution according to the invention is the technical effect consisting in the fact that the method of fixing the nozzle tip in the nozzle head guarantees its resistance to bursting even at higher pressures above 7 MPa with a high production of about 90 % of dry fog particles with particles smaller than 10 µm. Contributing to this effect is the fact that the flow outlet channels for dispensing the fluid are not located in a movable member, e.g. the piston in the nozzle head, but are formed on the inner surfaces of the nozzle tip and are terminated by the outlet orifice with a very small cross-section that leads into the cavity of the jet orifice, which also provides an immediate effect of the production of dry fog particles with particles smaller than 10 µm. The triangular flat cross-section of the flow-through outlet channels is essentially a Venturi tube, where the Bernoulli equation implies an increase in the velocity of the outflowing medium in the outlet orifices of the flow-through outlet channels, which results in a more efficient atomization of the fluid into a non-condensable dry fog.
