Abstract

The present invention relates to a decontamination device of the type comprising a compressor (1) supplying pressurized gas, with interposition of means of pressure regulation, means (5) suited for misting a decontamination product in the form of fine droplets in a room to be treated. This device is characterized in that the compressor (1) directly supplies the means of misting (5) at a desired pressure for use, and without interposition of a buffer tank, where the means of pressure regulation (11) are constituted by a controlled flow rate leak between the outlet (S) of the compressor (1) and the inlet (E) of the means of misting (5).

Claims

1. A decontamination device of the type comprising a compressor (1) supplying pressurized gas, with interposition of means of pressure regulation, and means (5) suited for misting a decontamination product in the form of fine droplets in a room to be treated, characterized in that the compressor (1) directly supplies a desired pressure for use (Pu) to the means for misting without interposition of a buffer reservoir, where the means of pressure regulation (11) are constituted by a controlled flow rate leak between the outlet (S) of the compressor (1) and the inlet (E) of the misting means (5).

2. Decontamination device according to claim 1 characterized in that it comprises means for control (11) of the flow-rate leak such that it will become active as soon as the pressure at the inlet of the means of misting (5) exceeds the desired pressure of use (Pu).

3. Decontamination device according to one of claim 1 or 2 characterized in that the desired pressure of use (Pu) is of order 3×

105 Pa.

4. Decontamination device according to one of the preceding claims characterized in that the compressor (1) is of the continuously operating type.

5. Decontamination device according to one of the preceding claims characterized in that the compressor (1) is of the oil-free lubrication type.

6. Decontamination device according to one of the preceding claims characterized in that the pressure regulation means are constituted of a mechanical regulation valve (11) formed of a body (17) provided with an inlet line (19) and an outlet line (13) to free air for which the connection is controlled by a valve reed (21) applied, in non-connecting position, onto a seat (23) by a spring (25) calibrated to a compression value near the recommended pressure (P).

7. Decontamination device according to one of claims 1 to 5 characterized in that the means of pressure regulation include pressure measurement means (40) placed in branches on the main line (3) connecting the compressor (1) outlet (S) to the inlet (E) of the misting means (5), which are connected to electronic analysis and control means (42) suited to control a valve (44) mounted in a branch on said main line (3), so as to activate the opening thereof when the pressure in the main line (3) exceeds the recommended pressure (P).

8. Decontamination device according to claim 7 characterized in that the electronic means are constituted by a microcontroller (42).

9. Decontamination device according to one of the preceding claims characterized in that means of pressure regulation are suited to generate a leak whose flow rate is larger when the pressure difference between the recommended pressure (P) and the compressor outlet pressure (1) is larger.
