Description

Technical Field

[0001] The utility model relates to the field of environmental protection ozone treatment, in particular to an ozone scrubber. Background Art

[0002] The scrubber currently used contains activated carbon and filter cotton. The initial scrubbing effect is consistent in a dry environment, but after long-term use, the activated carbon can no longer adsorb more ozone molecules, resulting in measurement deviations of the analyzer. When tested in an environment with a certain humidity, because it contains filter cotton, water vapor has a certain impact on the UV measurement. At this time, the water vapor that has passed through the scrubber is adsorbed, and the water vapor that has not passed through the scrubber still exists, resulting in the final measurement being unable to offset the water vapor interference. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide an ozone scrubber to solve the problems raised in the above background technology.

[0006] As a further improvement of the utility model, the catalytic tank has a stepped structure, the middle of the catalytic tank is a cleaning sheet position, the upper part of the catalytic tank is an end cover position, the bottom of the catalytic tank is a cavity, the cleaning sheet position is used to place the steel mesh, and the end cover position of the catalytic tank is used to install the end cover.

[0007] As a further improvement of the utility model, the air inlet hole 1 is communicated with the upper part of the scrubbing sheet, and the air outlet hole is communicated with the cavity at the bottom of the catalytic tank.

[0008] As a further improvement of the utility model, solenoid valves are respectively installed on the air inlet hole 1 and the air inlet hole 2.

[0009] As a further improvement of the utility model, the end cover is threadedly connected to the end cover position of the catalyst tank, and a sealing gasket is provided between the end cover and the catalyst tank.

[0010] As a further improvement of the present invention, the apertures of the steel meshes are different, and the holes on the steel meshes are staggered to ensure the passage of gas.

[0011] The beneficial effects of the utility model are:

[0012] The cleaning effect of this device is better. The ozone analyzer needs an ozone scrubber to compare its signals and obtain the corresponding ozone concentration value. The manufacturing method of this scrubber has the effect of catalyzing ozone instead of reaction or adsorption. It is long-lasting, non-toxic and harmless, and will not absorb water vapor.
