Description

[Detailed description of the invention] This blindness is caused by the deodorization of dirty air in hospitals, factories, etc.
HT is an air purifier that uses ozonated water for sterilization and dust collection.

Conventional devices of this kind have performed deodorization and sterilization by raindrops of ozonated water on dirty air, but due to the nature of the raindrops, there is a limit to their size, and the contact between the air and the raindrops has been limited. It is difficult to increase the processing capacity by increasing the area.

The purpose of this invention is to obtain an air purifying device that has a higher processing capacity compared to the case where deodorization is performed by making raindrops fall, and to obtain a device that can further expand the contact area. Another purpose is to effectively use surplus ozone when obtaining ozonated water by bringing it into contact with the air to be treated.

This invention will be explained with reference to the attached drawings. A spray/throttle 3 is provided above the packing 2 located in the middle of one packed column 1, and above it, a mist removal device 1t+, activated carbon 5 and a suction fan 6 are installed. [111H] An ozone water hopper 7 is provided below the filling material 2, and a to-be-treated air introduction duct 8 and an ozone gas supply pipe 9 are connected above and below the hopper 7, respectively. Air communicated with hopper 7 through pump 10 and tohyft 11? In some devices, the filling material 2 is made by laying stainless steel wire in a mesh or by laying the stainless steel wire in a mesh. ! These are fillings used in ordinary scrubbers, such as flat-formed pebbles, plastic pebbles, or cetomic pebbles. Further, an ozonizer 12 is connected to one end of the ozone gas supply pipe 9, and the ozone gas generated by this is sent to the ozonizer 12 at the other end of the ozone gas supply pipe 9, and then sent to the ozonizer 12 in the hopper 7. The ozonated water 14 is sprayed in the form of bubbles into the thin water 14, and at this time the ozone in the ozone gas is absorbed into the ozonated water 14. This force is sprayed towards the top surface of the filling layer 2, slips and bends on the surface of the filling material 2-, that is, stainless steel wire or plastic head A/, and flows down into the hopper 7. Go back and repeat the ozone absorption and spray described above again.

During this time, the air to be treated supplied from the introduction duct 8 entered the air space 15 between the lower surface 2& of the trivial filler 2 and the free surface 14& of the ozone water pipe 4, and thus passed through the ozonated water 14. It is mixed with ozone gas to be deodorized and then moved up through a gap of 2 centimeters between the fillers.

At this time, on the surface of the filling that was placed first? It is deodorized and sterilized by coming into contact with 72 areas of thick ozonated water descending.
Then remove the mist*! I! through device 4 and activated carbon 5! ! 1
Dehumidification and ozone removal are performed, and the air purified through this process is inhaled (g&jj1 with 7 amps 6 and discharged 1

In addition, when the dust contained in the treated air comes into contact with ozonated water, it enters the ozonated water Q*Tsuba 7 vi
It settles to a depth of 1 m and forms a dust layer 18 on top of the pulp 17. When the elephant passes through the shrine, turn the handle 19 to surround the pulp 17 and dispose of it outside.

At this time, the free surface level 14 is kept constant by supplying fresh water commensurate with the size of the hopper into the hopper through a supply pipe not shown in the figure.

By enlarging the contact surface gIf,t between the straddling air and ozonated water, the ability to treat a-odors and the like can be increased.

In addition, a spray/throttle 3 is installed above the packed bed 1, and an ozonized water hopper 7 is provided below, and the hopper 7 and the spray nozzle are communicated with a pump and a pipe, so that the 13fi air rises at intervals of 20 minutes. At this time, the filling material 20 flows in opposite directions and comes into contact with the falling ozone water while wetting the surface of the filling material 20, increasing the friction of the contact. Also, the ozone gas that is not absorbed by the ozonated water in the hopper 7 by the gas supplied from the ozone gas supply pipe 9) becomes bubbles and rises from the free surface force of the ozonated water and mixes with the gas to be treated. However, since the ozone rises through the gap between the fillers 20 and 1, the air to be treated can be deodorized and sterilized at this time as well, and the ozone that was not absorbed by the ozone water in the hopper 7 can also be fully utilized. can.

Although the non-invention has been explained above based on Figure 1, the non-invention is not added to the embodiment shown in the same figure, and can be added.

In the embodiment shown in Figure 2, an ozonizer and dust charging device is installed in the introduction duct 8 of the embodiment shown in Figure 1, and the ozone gas generated by this is mixed into the air to be treated, and the ozone gas is mixed into the air to be treated. At that time, it comes into contact with the descending ozonated water to deodorize and sterilize it, and the descending ozonated water absorbs ozone gas, which is stored in the hopper as ozonated water with a high ozone concentration, and then pumped again by the pump 0. At the same time, the dust in the dirty air that is sent in from the introduction duct 8 is charged, collected by the filling material 2, and washed off with ozonated water, and then sent into the hopper 7. It is collected and precipitated to form the dust layer 18.

This dust storage and ozonizer is made of high-purity alumina! A substrate made of fine ceramic glass such as porcelain or a suitable #Tunbon is provided with a line 21't' on one side, and a line 21't' is provided on the circular part of the substrate or on the other side. A ridge pole 22 is provided, and between the two IE poles 21 and n there is an i-field device that interposes a part of the circuit board that constitutes the IE pole, and a high frequency power supply n is stored in the two poles. Furthermore, it faces the position opposite to the two linear discharge electrodes of the front electromotive field installation! Once the IC poles 24 are installed, a DC high voltage power supply 25 is connected between them, and the discharge electrode 21 is
The ionic current flowing from the ion current towards the opposing N tip causes the dust flowing there to become more easily collected by the filler 2.

In the embodiment shown in Figure 24, a pipe 26 connects the hopper 7 and the pump 10, which are used in the embodiment shown in Figure 1, and an ozonizer 12a is connected to this pipe. ) is mixed into the ozonated water inside the pipe flowing towards Bonpue 0, increasing the ozone a degree, and that'! ! The water is fed into the spray/through 3 shown in Figure I. However, the 12m length may be an ozonated water generator that combines an ozonizer and a bubbling device.

In the case shown in Figure 5, ozone generated by an ozonizer is introduced into an inlet duct 8 through a connecting pipe 9, and introduced into the lower space 15 of an upper-packed tower where it is added to and mixed with dirty air within the inlet duct.
The gap between the fillers 20 is raised to make contact with the flowing water on the surface. In this case, most of the ozone is absorbed by the flowing water and becomes ozone water, effectively absorbing and removing contaminants in the gas. and falls into the hopper 7 below.
