Yet another object of the present invention is the catalytic removal of carbon by converting it into 2R-ride.
The heat generated by the pneumatic sardine can be used to provide thermal energy to the ytlc op@ration.

The conventional atmospheric treatment method is C? It is thought that the oak is bound with sufficient purity to evoke the polished luster of the wood.

For this reason, it is currently preferable to generate the evening air used for treatment by mixing pure imaginary and pure imaginary, but with the caveat that the production of this method JiA111 [l is the specific yield I I'm jealous of you.

Therefore, the purpose of this 9-color light is to reduce the atmospheric pressure (!'m FJ) to generate 1 ton of nitrogen gas (quickly), and to eliminate all the pollutant gases and bacteria in A41. The production cost can be reduced to a level much lower than the cost of the known method of mixing pure wax with pure V system in order to obtain the desired rope + II and to create a non-occlusive nitrogen atmosphere. It is to wait.

The method according to Kimi J. uses at least one dry piston compressor to compress the atmosphere, and then uses this atmosphere to carry out the treatment steps: A process of passing through the gas to a thin micron size, - a drying process, removing the contaminant gas, - a second process of filtration to a micron size, and a process of removing bacteria. According to the present invention, this method is equipped with two suction-arm layer filters that filter active fJIJ* of the same nature for the drying step and the gas removal step. The process is carried out on the -F side of the etiquette process, and the drying equipment is characterized by the fact that the gas is used to remove the gas from the drying process.

More specifically, equipment that has been covered to remove contaminated gases must be kept dry! 11! The activity 91 must be approximately 50 percent more active than the device location.

According to a further feature of the invention, the removal of bacteria is accomplished by sequentially passing compressed nitrogen air through three joint filters such that the air flow has a constant threshold of 0.01 microns. Q#
Particularly, the sterilization process is carried out within this continuous three-stage filter, and the external sterilization process is provided on the F flow side of the three-stage filter.

The method of the present invention further comprises filtering the cocoon a through a -slow filter.

It is preferable to arrange the climate changer 10 and its 55LA device 11 on the F flow side. Therefore, the carbon dioxide contained in the atmosphere is removed by the extractor, and the platform where the carbon dioxide is otherwise removed is transferred to the atmosphere by the contact device IO and its exchanger 11. It is satisfied by converting the monosulfurized back element. In this case, contact device 1
0 and its father return device are preferably interposed between the second bacterial filter 18 and the first bacterial filter 21. Two pulps 12 and 13 are placed at the input port of the contact SM device IO and the output port of the capacitor 11, respectively.

In addition, the bypass line 14, which is placed in parallel with the duct 2 and controlled by the valve 5, prevents any carbon from entering the airflow. It is possible to directly supply airflow to the vessel 17.

It is also possible to provide other backup circuits (not shown), and in this case, the backup circuits are Tsuyoshi 1! Equipped with an IT converter and a cooler.

4. Drying and Removal of Contaminated Gas The airflow leaving the cooler 211 is completely dried by passing through the desiccator 16 which operates on the principle of absorption and extraction.

The adsorbed water molecules are released, and the dry heat from the blowing cylinder releases the adsorbed water molecules. Blow in the direction of discharge P @ Buddha.

This polar facing is sold by the applicant under the trademark 1) NSSICAlB. This drying operation is necessary to remove all the water vapor that was not extracted by condensation in the buffer tank 6 during the pre-recording process.

A device 17 for removing contaminated gas, usually called a "desulfurizer", is arranged below the desiccator 16 on the VRT side.

The purpose of this desulfurizer is to remove sulfur dioxide gas, hydrogen peroxide, peroxide, carbon dioxide, carbon dioxide steam, Fuki, US, and mercaptan. The 1° desulfurizer 17, which is necessary to remove tetraethyl lead, tetramethyl lead, and all the other undesirable gases commonly present in urban air, is a device similar to the desiccator 16 and uses the same adsorption-stratification principle. It also works as an activator, as well as potassium silicates and oxides.

It is a compound with sodium chloride and magnesium chloride. However, the composition ratio of the active substance is very small in the case of external force, and the amount of active substance in the desulfurizer is larger than that in the desulfurizer. In favor of Sari, to RAC Gm
It is preferable to use it in a desiccator manufactured by IA as No. 542, and the amount of purchase of this machine piece is 50 cents more than the desiccator.

The removal of 4JI & 517 is effective in removing pollutant gas as well as air odor. Stratification is done using desiccator 16.
The delayering temperature is 220℃, which is higher than 180℃.

O-8 meters) means one technique and one buttock. Super 1? Due to overwork, the known joint fill 21.22.
Three filtration parts 23i are connected in series, one filtration part is covered with a porous plastic jacket, and the other part is made of a mat made of borosilicate glass fiber. p between filters depending on the density of glass fibers
The rate of decrease of unfortunate pupils is determined. Therefore, the first filter 21
In this case, the over-threshold value is 0.6 microns, and the threshold ml of the second and third filters 22.23 is 0.01 microns above.

In addition, the second filter 23 is used not only to keep track of bacteria, but also to complete the deodorizing effect of eradication and destruction m17.
It includes a suction denoku chair for the first grade of the craft. Collaborative filters such as filters 21, 22, 23 have been proposed by the applicant as PFM+5IVIB and 1.2, respectively. ) It is commercially available for 800 people. The pulps 24 and 25 of 21161 are prepared for the extraction and exit stages of the extraction process, respectively.

A cooling sterilizer 26 of known type is placed on top of the pulp 24. The sterilizer includes a cartridge of hydrophobically treated silicate glass Ra1d, which is housed in a stainless steel frame. This type of sterilizer is sold by the applicant under the number STR. The pulp 27 is loaded onto the sterilizer 26, so that by closing the pulps 25 and 27, the sterilizer can be isolated for periodic sterilization. Pulp 27 T
On the m side, there is an extraction pulp 28, a conventional shutoff valve 29, a discharge duct 30 with a pressure resistance 31, and a safety pressure sensor J2.

29' and extracted pulp 28'.

The exhaust duct 30 is conventionally connected to a ventilation distribution system in a hospital or hospital. In order to increase the efficiency of this discharge tact, it is better to equip the storage cylinder with an appropriate device (see figure) for purification time.

In the system described above, a conversion device lO is installed between the first dust filter 7 and the desiccator 16, but in another advantageous embodiment this conversion device is installed between the combinator and the buffer tank 6. The heat capacity of the airflow exiting the compressor is utilized to reduce the heat drop required for contact action.

According to a variant advantageous to the filter, the filtration is carried out through each filter through the second joint filter 2 of said bacteria removal stage.
Up to 2, the airflow is broken by the low air mε, and the airflow passing through the third filter 23 and the sterilizing iron 1iij 26 is speeded up by 1. It is better to place both filters, preferably activated carbon, directly in the second position rather than in the third position.

As a result, the transit device installed on the upstream side of the third bacterial filter 23 will be clogged too quickly, and therefore, a single batch of bacteria will appear in the entire V3 Temple 2 Inn. It is possible to achieve an over-effect when using the M-effect. This method also. The process air stream is brought into contact with the deodorizing components of the second common filter 22 during the filtration process over a period of time, thus achieving a more complete deodorizing effect.

Finally, by slowing down the air flow through most of the equipment, the pressure when passing through the filter can be significantly reduced.

Therefore, the air velocity passing through the final common filter 23 and the sterilizer 26 is 1.5 of the velocity passing through the remaining device.
It is preferable that the speed is three times faster than the previous one.

A simple way to slow down the air flow through the filters placed upstream of the final joint filter 23 and the sterilizer 26, and thus accelerate the air flow through these last two devices, is to One side of the device located upstream of devices 23 and 26 can be provided with an oversized passage area.
