(Prior art) Generally used as a working medium for refrigerators, power generation plants, etc.
When fluorocarbons are introduced into the circulation flow path of the plant using feces, air is already present in the circulation flow path, and if the above plan 1- is relatively large scale, fittings such as flanges should be installed on the piping. Even if a sealed structure is adopted, it is impossible to prevent a small amount of air from entering the circulation channel from the flange portion. For this reason, when the air in the pipes is cooled, moisture is generated, which oxidizes the metals of the plant's pipes, etc., causing so-called clogging fTk'
& occurs within the (circulation flow path). The air (more precisely, oxygen in the air), moisture, rust, etc. (hereinafter referred to as acid content, etc.) in the circulation flow path of Plan 1- above functions as a working medium for Freon. Close. Therefore, in the past, a bypass line was installed in the th'i 5'J flow 1-8 of the plant, and when the fluorocarbon was immersed and recovered, and during blunt operation, a bypass line was installed in the th'i 5'J flow 1-8. By putting an adsorbent into the fan 1-1, impurities such as the above-mentioned acid content present in the fan 1-1 were removed (hereinafter referred to as cleaning of the fan 11).

However, when cleaning fluorocarbons using this method, it is necessary to stop the operation of the bar f pass line in the circulation flow path when replacing the adsorption shrine, and it is necessary to prevent fluorocarbons from leaking by opening the valve. This lowers the removal rate of water, acids, etc., and on the other hand, when taking out the fluorocarbons, the gasified and expensive fluorine present in the fluorocarbon flow path is released into the atmosphere. There was an economic waste.

On the other hand, during operation of an oil-tight plant, as shown in Fig. 3, input/recovery valves 8.9 and IO are closed, and inlet valve 5.
When the outflow valve 6 is opened, due to the action of the fluorocarbon pump, the circulating flow of the plant is 1/N, which is formed by the fluorocarbon condenser 3, the fluorocarbon pump 4, the evaporator, etc., only a part of which is shown in the figure. In the circulation flow path (indicated by thick line) of this cleaning system, which is installed in parallel with (indicated by near 1- line),
A part of the fluorocarbons flows through the filter l, so impurities such as acids are filtered out, i.e., the eyebrows:
l'/+ is applied. In this process, 7) When the adsorbent in the filter l is saturated, that is, the filtration lj, u fil is exhausted, the switching valves 28, 2+1 on the inflow and outflow sides are switched to the opposite side, for example, from left to right. If so, it is possible to continuously wash the fluorocarbons by operating Plan 1 and the circulation flow path of the washing system every 11 days.

In addition, when replacing the adsorbent in the filter 1 that has reached the saturated state, open the nitrogen purge valve I9 of the nitrogen purge line 20 to be replaced, and open the nitrogen purge valve I9 between the inflow and outflow valves 28 and 21I. CFCs present in the pipes and filter 1 are purged with nitrogen. For this reason, when replacing the adsorbent, there is no need to release the dregs that exist in the Plan 1 pipe (iL'i return flow path), and there is no need for air to get mixed into the pipe. can be prevented from happening. Nitrogen remaining in Tsuruji does not interfere with the function of Freon as a working medium.

As explained above, according to this device, fluorocarbons mixed with impurities such as acids do not enter into the circulation flow path of the bran 1, and even if they do, they can be cleaned without interrupting operation. Furthermore, since this cleaning device is equipped with multiple cleaning means in parallel, continuous bL cleaning can be achieved by simply switching the switching valve when one of the cleaning means reaches the saturation state, and the above-mentioned It is possible to replace the adsorbent, etc. of the cleaning means without having to interrupt cleaning. 1i
f ζ, how many steps should the cleaning device according to the present invention be shifted to obtain F I-1?
When cleaning the plant, the plant can be kept running at all times, so there is no need to stop its operation, which has a very large economic ripple effect that is beyond the scope of the technical results of the present invention. There is.
