The present invention relates to an air filtration system. More specifically, the present invention relates to a double-sided dry air filtration system having both sides of a high-temperature, high-pressure dry gas injector for automatically dehydrating and drying both sides of a cleaned air filtration filter.

To supply clean air to the room.

Such a conventional air filtration system is provided with several filter units which have a mesh-shaped dust collector which traps dust in the air. However, if the dust is stuck to the dust collector by using the filter unit for a predetermined time or more, the filtering function cannot be efficiently performed. Therefore, the filter unit should be replaced or at least cleaned.

However, when cleaning or replacing the filter as described above, there is a problem in that the work space is narrow and the work is difficult, and the air conditioner cannot be operated while the work is in progress.

However, when the filter of the air filtration system is cleaned, dust or bacteria are collected again in the filter in which the cleaning liquid remains, so that dust adheres to the filter or bacteria grow. In this connection, there is a need to rapidly dry and dehydrate the cleaning liquid remaining in the filter after cleaning. In addition, in the low temperature state such as winter, the cleaning liquid freezes in the pipe or the nozzle and the pipe or the nozzle is clogged, so that the air filtration system cannot be cleaned during the winter.

In consideration of this, in the conventional air filtration system, such washing water is injected into the filter, and only residual gas remaining in the pipe is removed by using a gas compressed at high pressure, and the filter is dehydrated and dried. Due to the removal of residual water and the increase of working time due to the sequential drying process, the drying efficiency is reduced, and there is a problem of a complicated configuration due to the addition of the compressor body supply unit / injection unit and the heating gas supply unit / injection unit. In addition, the filter always has both sides, the drying operation of the filter is performed only on one side of the filter, there was a problem that both sides of the filter can not be dried at the same time.

The cleaning solution supply unit 110 of the air filtration system 100 according to an exemplary embodiment of the present invention provides power for delivering the cleaning solution from the hot water heating type cleaning liquid tank 112 and the hot water heating type cleaning liquid tank 112 in which the cleaning liquid is stored. A pressurized pump motor 114 is provided.

As shown in FIG. 2, the heating means 116 is provided inside the hot water heating type washing liquid tank 112 to heat the washing liquid to an appropriate temperature. The heating means 116 may directly or indirectly contact the cleaning liquid in the warm water heating type cleaning liquid tank 112. The cleaning solution is preferably maintained by about 70 degrees Celsius by the heating means 116.

On the other hand, the high temperature and high pressure dry gas supply unit 110 is a blower 124 and the motor for transmitting power to the impeller of the blower 124, for example, the electric motor 122 and the power of the electric motor 122 to the blower It includes power transmission means such as a belt for transmitting.

The temperature and pressure of the gas discharged into the discharge port are much higher than the temperature and pressure of the gas flowing into the inlet. The gas introduced into the blower is air around the blower, and is generally air at room temperature. However, the temperature of the gas discharged through the discharge port 124d of the blower 124 is a hybrid blower that generates a heat source by using the principle that the temperature is increased by at least 60 degrees above normal temperature.

Specifically, the air filtration system 100 includes a first flow control valve 140 for controlling the fluid flow between the cleaning liquid pipe (L1) and the connection pipe (L2). In addition, the air filtration system 100 includes a second flow control valve 150 for controlling the fluid flow between the high temperature and high pressure dry gas pipe (L3) and the connection pipe (L2).

The first flow control valve 140 and the second flow control valve 150 control the flow path of the pipe so that the high-temperature, high-pressure dry gas flows into the pipe through which the cleaning liquid supplied from the cleaning liquid supply unit 110 flows.

Basically, the first flow control valve 140 controls the flow such that the cleaning liquid supplied from the cleaning liquid supply unit 110 flows through the cleaning liquid pipe L1 to reach the filter assembly 130. The second flow control valve 150 also basically controls the flow such that the high temperature high pressure dry gas supplied from the high temperature high pressure dry gas supply unit 120 reaches the filter body 130 through the high temperature high pressure dry gas piping L3. do.

As will be described later, injection nozzles are respectively connected to the cleaning liquid standing pipe and the high temperature and high pressure dry air standing pipe assembled by brackets to a conveying device which is moved left and right toward the filters of the filter body, and the surface of the filter is formed by the respective injection nozzle parts. The cleaning solution is first supplied to the cleaning solution, and after the cleaning is completed, the control panel 90 controls the high temperature and high pressure dry gas to automatically remove the residual water from the cleaning pipe and the residual water from the filter surface.

Meanwhile, referring to FIGS. 1, 2, 4, and 5, the filter main body 130 branches from the cleaning liquid standing pipe 132a for supplying a cleaning liquid to the air filtration filter F and the cleaning liquid standing pipe. High temperature and high pressure dry gas standing pipe 132b1 for spraying one side of the filter for supplying a high temperature and high pressure dry gas to a surface of the cleaning liquid injection nozzle 133a and one side of the air filtration filter F which extends in parallel to the surface of the filter. And a high temperature and high pressure dry gas injection nozzle part 133b1 for injection on one side of the filter which is branched from the high temperature and high pressure dry gas standing pipe 132b1 for injecting the other side of the filter and extends in parallel to one surface of the filter.

If the air filtration filter (F) is assembled inclined in the filter body 130, the cleaning liquid spray nozzle portion 133a and the high temperature and high pressure dry gas spray nozzle portion 133b1 for spraying one side of the filter are also inclined along the inclined filter surface. It is assembled obliquely. The high temperature and high pressure dry gas injection nozzle part 133b2 for spraying the other side of the filter is assembled to have a reverse inclination parallel to the high temperature high pressure dry gas injection nozzle part for the injection of the one side of the filter 133b1.

A plurality of cleaning liquid nozzles 134a are disposed at predetermined intervals in a direction toward the one side surface of the filter F from the cleaning liquid injection nozzle unit 133a. Similarly, the filter one side high temperature and high pressure dry gas nozzle 134b1 is disposed at predetermined intervals in the direction toward the surface of the filter F from the high temperature and high pressure dry gas injection nozzle unit 133b1 for injection on the one side of the filter. The number of nozzles and the spacing of the nozzles are determined so that the fluid can reach all surfaces of the nozzle in consideration of the spray angle at which the fluid injected from the adjacent nozzles reaches the surface of the filter.

Here again, the number and arrangement of nozzles are determined so that the fluid reaches all surfaces of the nozzle in consideration of the spray angle at which the fluid injected from the adjacent nozzles reaches the surface of the filter.

As shown in FIGS. 1 and 5, the air filtration filter F is formed by the upper casing 131, the side casing first side 131a and the side casing second side 131b in the main body where the filters are combined. In the inner space to be assembled, a plurality are arranged in the transverse direction and arranged in multiple stages in the longitudinal direction.

The air filtration filter F disposed at the stage of the same height is separated and supported by the air filtration filter F disposed below by the intermediate tray plates 138 being slightly gradientd. Therefore, even if the cleaning liquid is injected into the air filtration filter F at the specific stage, the cleaning liquid is guided by the intermediate tray plate 138 and the main body side drain guide plate 138a, and the upper portion of the air filtering filter F at the lower stage thereof. Gradient is drained to the side drain guide plate (138a) without directly falling to the water, and finally the cleaning liquid reaching the lower tank of the filter main body is drained through the drain hole (139).

As shown in FIG. 1 and FIG. 2, the air filtration system 100 according to the embodiment of the present invention includes the cleaning liquid standing pipe 132a and the high temperature at which the gas and the cleaning liquid are fluidly connected to the cleaning liquid pipe L1. An air filtration filter (F) disposed in a plurality of stages in the vertical direction by supporting the high temperature and high pressure dry gas standing pipe (132b1) for injection on one side of the filter in which pressurized air is flowably connected to the high pressure dry gas pipe (L3) in the vertical direction. Further, a first support 137f for moving the cleaning liquid pipe 132a and the high temperature and high pressure dry gas standing pipe 132b1 for injection on one side of the filter to spray the cleaning liquid and the high temperature high pressure dry gas on each surface of the Include.

The first support 137f vertically supports the cleaning liquid standing pipe 132a and the high temperature and high pressure dry gas standing pipe 132b1 for spraying one side of the filter in a vertical direction, and the cleaning liquid standing pipe 132a and the one side of the filter. Use high temperature high pressure dry gas standing pipe (132b1) serves to be fixed and moved by the transfer device and the connection bracket.

The first support 137f is a high temperature and high pressure dry gas standing pipe 132b1 for supplying a cleaning liquid through the cleaning liquid standing pipe 132a and spraying one side of the filter when the first support 137f is observed based on a specific same portion of the air filtration filter F. The high temperature and high pressure dry gas standing pipe for injection of the cleaning liquid standing pipe and the filter side is supported so that the supply of the high temperature and high pressure dry gas through the filter is sequentially performed. Therefore, while the cleaning liquid standing pipe 132a and the high temperature and high pressure dry gas standing pipe 132b are also moved along the moving direction of the first support 137f, the cleaning operation is first performed while being moved left and right on the surface of the air filtration filter. After cleaning, the residual water in the pipe is removed, and then a dehydration / drying process of blowing water droplets remaining on the surface of the air filtration filter by surface tension is performed. When the cleaning operation is performed, the pressurized pump motor 114 is operated and is cleaned. After that, in order to remove the residual water in the pipe, the pressure pump motor 114 is stopped, and the electric motor for supplying the high temperature and high pressure dry gas should be immediately started. In addition, the flow control valves of the air pipe (L3) must be controlled in order to dehydrate / dry the water droplets remaining on the surface of the air filtration filter. A hybrid process to quickly correct the coefficients to raise the temperature to prevent freezing should be built into the circuit of the control panel 90.

1, the cleaning liquid standing pipe 132a is assembled in the direction toward the side casing second side surface 131b by the first support 137f, and is a high temperature high pressure dry gas standing pipe. 132b are divided and assembled in the direction toward the side casing first side surface 131a, respectively.

The first support 137f is installed to rotate left and right on the first transfer device 135f extending over the side casing first side surface 131a and the side casing second side surface 131b. The movement on the first transfer device 135f of the first support 137f is rotated to the left and right by the operation of the first support geared motor 136f installed on the first transfer device 135f.

As the first support 137f moves in the direction from the side casing first side surface 131a to the side casing second side surface 131b, the entire surface of the air filtration filter F disposed in multiple stages in the vertical direction is formed. The cleaning liquid injection is performed first, and then the high temperature and high pressure dry gas is injected, and the two fluids are sprayed and cleaned evenly across the whole while moving left and right with respect to the entire filter, and the high temperature and high pressure dry gas is applied to the entire air filtration filter (F). Spray cotton on both sides to dry.

When the first support 137f reaches the part adjacent to the side casing second side surface 131b, the support is completed for cleaning, dehydration and drying of the air filtration filter.If necessary, the support is returned to its original position and washed and dewatered again. And drying operations.

On the other hand, in order to dry the other surface of the air filtration filter (F), the air filtration system 100 according to an embodiment of the present invention is the other side of the filter in which fluid is fluidly connected to the high-temperature high-pressure dry gas pipe (L3). The other side of the filter to support the high-temperature high-pressure dry gas standing pipe 132b2 for injection in the vertical direction to inject the high-temperature, high-pressure dry gas to each other surface of the air filtration filter F arranged in multiple stages in the vertical direction. It further comprises a second support 137b for moving the injection high temperature high pressure dry gas standing pipe 132b2.

The second support 137b moves along the second horizontal member 135b disposed in the horizontal direction similar to the first support 137f, and transports the high temperature and high pressure dry gas pipe 132b2 for spraying the other side of the air to air. The high temperature, high pressure dry gas can reach the other surface of the filter. The high temperature and high pressure dry gas standing pipe 132b1 for spraying one side of the filter and the high temperature and high pressure dry gas standing pipe 132b2 for spraying the other side of the filter should be driven by respective geared motors.

In the process of sequentially cleaning, dehydrating and drying the air filtration filter, the first flow control valve 140 may allow only the washing water heated by the hot water from the cleaning liquid supply unit 110 to the filter assembly 130. The flow control valve is controlled, and the second flow control valve 150 controls the fluid flow to allow only the high temperature and high pressure dry gas from the high temperature and high pressure dry gas supply unit 120 to the filter assembly 130. Therefore, the flow of the washing water through the connecting pipe (L2) in this process is blocked.

Subsequently, after the cleaning, dehydration, and drying operations for the air filtration filter are completed, a residual cleaning liquid remains inside the cleaning liquid pipe L1, and when left in that state, the cleaning liquid may be condensed. In order to prevent this, it is necessary to remove the cleaning liquid remaining in the cleaning liquid pipe L1. To this end, the second flow control valve 150 controls the flow direction so that the high temperature high pressure dry gas flows from the high temperature high pressure dry gas pipe L3 to the connection pipe L2. In this case, the first flow control valve 140 controls the flow direction such that the high temperature and high pressure dry gas flowing through the connection pipe L2 flows to the filter assembly 130 through the cleaning liquid pipe L1. Therefore, the washing liquid is completely discharged through the pipe, the pipe, the spray nozzle, and the nozzle in the filter assembly direction by the force pushed by the high temperature and high pressure dry gas. The high temperature and high pressure dry gas may be operated to remove the washing water remaining in the pipe and to dry the cleaning liquid attached to the filter surface on both sides, and additionally the high temperature and high pressure dry gas may be supplied to the filter assembly on both sides.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
