[001] The present disclosure described herein focusses on the development of a spray assembly for disinfecting airborne bacteria, viruses, and fungi within an enclosed space. More particularly, the present disclosure focusses on the development of a spray assembly for disinfecting the Covid-19 viruses within an enclosed space.
BACKGROUND
[002] Covid-19 pandemic is having a major impact on all economic activities of the world. Many companies have been shut down, supply chain disruptions in many sectors have been witnessed, the results of which shall become more pronounced in the future. For a world that is trying to come to the normal situation, there is a need for quickly resuming and ramping up of the manufacturing activities, which would help in the restoration of the normal condition and avoiding shortages that may adversely affect the international economic recovery. It is a prerequisite to disinfectant all the working places/company premises/manufacturing plants with spraying water-based disinfectants to control the spread of COVID 19 microbes.
[003] These bacteria and viruses may cause sicknesses such as a cold, flu, or irritation or exasperation of allergies. Various cleaning products are already available in the market to reduce or eliminate bacteria such as liquid or spray disinfectants. Liquid disinfectants are usually mixed with water and used to clean surfaces such as bathroom/kitchen counters, kitchen sink areas, walls, and baseboards. This method of surface cleaning may be effective in reducing bacteria up to a certain extent.
[004] Airborne bacteria and viruses may be controlled through the use of spray, filters, and air cleaning assembly. Filters within an HVAC system may include webbing and chemical treatments that attempt to reduce the concentration of airborne bacteria. Specially designed filtered assembly may be placed on a floor or a desktop that helps to filter and recirculate air being treated through the filter assembly. Furthermore, sprays have been developed through the use of cans that emit disinfecting solutions into the atmosphere of a room. The emission of disinfectant spray is usually through a handheld can and is sprayed over a limited area for a short period of time and surface area.
[005] The use of disinfectant spray may be more effective if a assembly is utilized to emit a consistent stream of evenly distributed disinfectant over an area of the enclosed space. Although the disinfectant sprays that are available in the market are not effective in disinfecting several household viruses and bacteria such as influenza, rhinovirus, respiratory viruses, Herpes Simplex I and II, Hepatitis A or Poliovirus Type 1. An effective disinfectant spray needs to include the ability to kill a high percentage of bacteria, fungi, and specifically to address the Covid-19 viruses.
[006] Moreover, in Thermal power plants/Heavy engineering industries, coal is used as one of the fuels for generating producer gas for heat treatment applications. Here coal is stored in the open storage yard which is then taken into coal conveyor, gas generator, and further, it will be turned into ash. In the yard, coal dust is suspended due to normal wind action. These problems reduce the safekeeping of both men and machines in the manufacturing plants considerably.
[007] JP5037141B2 provides the mixed-phase mist spray system that is equipped with a microbubble producing assembly for producing microbubbles of air in a liquid, a liquid pressurizing assembly for pressurizing the liquid mixed with the microbubbles and a sprayer for spraying the pressurized liquid as a fine particulate mist mixed with the microbubbles by a one liquid system. This mixed-phase mist spray system sprays the mist in a large amount of air without wetting an indoor wall or article. It is used for indoor wall applications only.
[008] Hence there is a necessity to find out a suitable spray assembly to disinfect the wide-ranging working spaces outside as well as inside and also suppress the coal dust in the open spaces to mitigate the dust/microbes related issues.

Also, as used in the description herein, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.
[030] The conventional spray assembly is generally effective while spraying the disinfectant based liquid in the inner area.
[031] To overcome the issues with the existing conventional spray assembly, the present disclosure herein provides a spray assembly which effectively sprays the disinfectant based liquids in both the inner and outer areas.
[032] Figure 1 illustrates the schematic arrangement of the various components of the spray assembly 100 applicable for spraying the disinfectant based liquids in accordance with an embodiment of the present disclosure. The spray assembly 100 comprises a spray head 104, a liquid passage 106, and an air passage 108. The liquid passage 106 is placed in the longitudinal direction of the spray head 104. However, the air passage is placed in the lateral direction of the spray head 104.
[033] The liquid passage 106 comprises a can 102 for storing disinfectant based liquids at high pressure of 10 bar having a liquid low-level sensor 132 that measures the level of the disinfectant based liquid in the can 102 and inform the user. The liquid passage 106 further comprises a liquid passage pipeline 124, a strainer 116 configured at the pump inlet to separate the large-sized particles from the disinfectant based liquid, a control valve 118 that controls the flow of high pressurized disinfectant based liquid from the can 102 to the spray head 104. A pressure gauge 120 is also installed on the liquid passage pipeline 124 to check the pressure of the disinfectant based liquid passing through it.
[034] The spray head 104 of the spray assembly 100 comprises a stainless steel annular ring 110 with an inner diameter(ID) 33.34 mm having the small inlet opening 130 with diameter 12 mm that facilitates the flow of pressurized disinfectant based liquid inside the spray head 104 from the liquid passage106. The annular ring 110 comprises a plurality of orifices 114 that are about 12 in number having diameter 0.3 mm that are placed equidistantly.
[035] On the other hand, the air passage 108 comprises an air duct nozzle 112 having a diameter of 360 mm at an exit that is connected with an electric fan 122. When the electric fan 122 is switched on, the air with velocity (9m/s) releases from the fan exit and enter the air duct nozzle 112 that increases the velocity of air up to 15.5m/s that creates low pressure and venturi effect near the intersection of air duct nozzle 112 exit and SS annular ring 110. This enables forced atomization (misting) of disinfectant based liquids entering inside the annular ring 110 of the spray head 104 through the liquid passage 106 which is coming out from the equispaced orifices (12 nos) with 0.3 mm diameter fixed on the SS annular ring 110, hereby contacting with air that helps in covering more area for suppression of dust/particles. Also due to pressurized liquid flow with fan 122 assisted high-velocity air leading to a throw length of atomized disinfectant based liquid in the range of 12m to 15m with said assembly. Moreover, the flow of disinfectant based liquid is around 3.6 liter per minute (lpm). Furthermore, the spray assembly 100 is a portable one and thereby the present disclosure improves biosecurity in the boundary/company premises.
[036] Figure 2 illustrates the front view of the schematic arrangement of the spray assembly 100 in accordance with an embodiment of the present disclosure. The spray assembly 100 comprises the SS (Stainless Steel) can 102. The strainer 116 is fixed in the pump inlet to ensure filtered water is only flowing into the system thereby eliminating visible contaminated particles in the water. The pressure in the pressured liquid passage pipeline 124 is controlled by using a control valve 118 and the pressure gauge 120 that is used to set & check the water pressure in the liquid passage pipelinne 124. The pressurized water of 10 bar is being pumped to the small inlet opening 130 (not shown) provided in the Stainless steel annular ring 110. On the other end, the SS annular ring 110 is mounted on the air duct nozzle 112 that is connected with electrical fan 122 which is in turn supported in the hinge unit 126 of C frame structure. Here, the spray head 104 is rotated up to 200 degrees (left to right) and tilting up to 90 degrees (up/down).
[037] When the fan 122 is switched on, the air with velocity (9m/s) passes through the air duct nozzle 112 that is increased up to 15.5m/s thereby it creates low pressure and venturi effect near the intersection of air duct nozzle 112 exit and SS annular ring 110. This enables forced atomization (misting) of disinfectant based liquids, which is coming out from the equispaced water nozzles 114 that is 12 in number having an exit hole of 0.3mm fixed on the SS annular ring 110, hereby contacting with air and covers more area for suppression of dust/particles. Also due to pressurized liquid flow with fan assisted high-velocity air leading to a throw length range of 12m to 15m with said system pressure and flow of water around 3.6 liter/minute. The entire unit 100 is fixed in a mainframe 128. It will be used for covering an area around 20 sq.m.
[038] Moreover, above the can, the liquid low-level sensor 132 is provided to protect the operator from any uncertainty if the water level in the can 102 falls below the desired level.
[039] Figure 3 illustrates the schematic arrangement of spray head 104 of spray assembly 100 in accordance with an embodiment of the present disclosure. The spray head comprises the stainless steel annular ring 110 having equispaced orifices 114. The pressured water line inlet (130) which is connected with annular ring 110 by ½” bsp threaded fittings. The annular ring 110 is made up of an SS tube (ID 3.34mm) with pitch circle diameter (PCD) 403 mm for spraying the disinfectant based liquids.
