Description

Technical Field

[0001] The utility model relates to an air purification device, in particular to a novel air dynamic sterilization and purification device which integrates multiple sterilization methods. Background Art

[0002] Air sterilization and purification devices mainly use a series of technical means to remove various pollutants from the air. The air purification method currently used in factories mostly uses only the fresh air system for primary filtration and ventilation of the air, and uses activated carbon plates for adsorption. When the air quality requirements are higher, additional separate UV sterilization and plasma sterilization methods are introduced. The overall sterilization and purification capacity is limited. During the purification process, the carrying capacity of adsorption and filtration components such as activated carbon is limited. If blockage occurs, it must be replaced in time. If a single purification method is used, the module may lose its purification capacity due to overload of the purification component, which requires high monitoring requirements and low fault tolerance. Summary of the Invention

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an air purification device with better sterilization and purification effects.

[0004] The utility model discloses an air dynamic sterilization and purification device, comprising a rotary dehumidifier, a centrifugal blower and an activated carbon filter installed at intervals along the air flow direction on the air inlet side of a ventilation duct. A bypass is opened on the ventilation duct behind the activated carbon filter. The inlet of an air analyzer fixed to the outer wall of the ventilation duct is connected to the bypass. A dynamic purification module is connected to the air outlet end of the ventilation duct.

[0005] The dynamic purification module includes a shell, with a partition arranged in the middle of the shell. The partition divides the middle part of the shell into two upper air channels and lower air channels separated from each other. The upper air channel is a sterilization and purification channel, including a first floating ball valve, an ultraviolet sterilization filter and a silver ion photocatalyst filter arranged in sequence in the upper air channel along the air flow direction. A second floating ball valve is installed at the front end of the lower air channel; a valve controller is fixed on the outside of the sterilization and purification device, the signal input end of the valve controller is connected to the signal output end of the air analyzer, and the two interfaces of the signal output end of the valve controller are respectively connected to the switch of the first floating ball valve and the switch of the second floating ball valve.

[0006] Advantages of the utility model: This structure is applied to activated carbon purification, ultraviolet sterilization and silver ion sterilization methods, which improves the air purification rate; each module is set independently, and combined with the plug-in structure to realize rapid installation of the filter, which is convenient for replacement and maintenance; an air quality analysis module is adopted to realize dynamic purification of air quality.

[0009] The present invention is described in detail below with reference to the accompanying drawings and specific examples.

[0010] As shown in the accompanying drawings, an air dynamic sterilization and purification device of the present invention includes a rotary dehumidifier 1, a centrifugal blower 2 and an activated carbon filter 3, which are installed in sequence at intervals on the air inlet side of the ventilation duct along the air flow direction. A bypass is opened on the ventilation duct behind the activated carbon filter. The inlet of the air inlet pipe of an air analyzer 4 fixed on the outer wall of the ventilation duct is connected to the bypass, and a dynamic purification module 5 is connected to the air outlet end of the ventilation duct.

[0011] The dynamic purification module 5 includes a shell, a partition is arranged in the middle of the shell, and the partition divides the middle part of the shell into two upper air channels and lower air channels separated from each other. The upper air channel is a sterilization and purification channel, including a first floating ball valve 6-1, an ultraviolet sterilization filter 8 and a silver ion photocatalyst filter 9 arranged in sequence in the upper air channel along the air flow direction, and a second floating ball valve 6-2 is installed at the front end of the lower air channel; a valve controller 7 is fixed on the outside of the sterilization and purification device, and the signal input end of the valve controller 7 is connected to the signal output end of the air analyzer 4, and the two interfaces of the signal output end of the valve controller 7 are respectively connected to the switch of the first floating ball valve 6-1 and the switch of the second floating ball valve 6-2.

[0012] Preferably, the activated carbon filter 3, ultraviolet sterilization filter 8 and silver ion photocatalyst filter 9 are respectively installed in the frame, and a ring platform is provided on each frame. A pipe inner wall ring groove is provided on the inner wall of the ventilation duct at the position corresponding to the activated carbon filter 3, and a shell inner wall ring groove is provided on the inner wall of the shell and the inner wall of the partition at the positions corresponding to the ultraviolet sterilization filter 8 and the silver ion photocatalyst filter 9. The ring platform on the frame at the activated carbon filter position can be inserted into the pipe inner wall ring groove, and the ring platforms on the frame at the positions of the ultraviolet sterilization filter 8 and the silver ion photocatalyst filter 9 can be respectively inserted into the shell inner wall ring groove, which can facilitate installation and disassembly. Of course, it can also be fixed with bolts or other structures.

[0013] The air in the air duct is blown in from left to right, and first passes through the rotary dehumidifier 1, centrifugal blower 2 and activated carbon filter 3 to complete preliminary purification. Part of the preliminarily purified air is diverted through a bypass to enter the air analyzer 4. The air analyzer 4 determines whether the quality of the preliminarily purified air meets the quality standards and transmits the detection result signal to the valve controller 7. The valve controller 7 controls the opening and closing of the first floating ball valve 6-1 and the second floating ball valve 6-2 based on the detection result signal to determine the air flow direction. Finally, the air is merged into the exhaust duct.

[0014] Here’s how it works:

[0015] When in use, this device is directly connected to an air duct. After entering the device, air in the duct passes through a rotary dehumidifier 1 to remove moisture. Then, a centrifugal blower 2 increases the air volume and pressure, increasing the air velocity. The air passes through an activated carbon filter 3 for preliminary dehumidification, dust removal, and sterilization. An air analysis module 4 determines whether the initially purified air meets quality standards. If the initially purified air meets quality standards, a valve controller 7 controls the second floating ball valve 6-2 to open and the first floating ball valve 6-1 to close, allowing the air to flow directly into the exhaust duct through the lower air passage. If the initially purified air does not meet quality standards, the valve controller 7 controls the first floating ball valve 6-1 to open and the second floating ball valve 6-2 to close. The air then passes through the upper air passage, passes through an ultraviolet sterilization filter 8 and a silver ion photocatalyst filter 9 for sterilization, and then flows into the exhaust duct.
