In the photocatalyst solution environment in the housing, formaldehyde is oxidized once from bottom to top, and then the formaldehyde air is oxidized to remove formaldehyde in the gaseous environment through the action of the circulating pump and the spray head, and finally the air intake is purified by the purifier. Three purifications have greatly reduced the content of formaldehyde in the indoor air.

In order to achieve the above object, the utility model provides the following technical solutions: a formaldehyde absorption and filtering device, including a housing, a collection cover and a suction fan, the bottom of the housing is provided with a photocatalyst solution, and the bottom of the housing is provided with a collection pipe, The collecting pipe is evenly provided with some air outlet holes, one end of the collecting pipe is connected with the collecting cover, and the other end of the collecting pipe leads into the photocatalyst solution at the bottom of the housing, and the outside of the collecting cover is provided with A formaldehyde concentration detector, a filter screen is provided in the collection cover, at least one suction fan is provided on the collection cover, a circulation pump is connected to the inner wall of the housing, a circulation pipe is connected to the circulation pump, and the bottom of the circulation pipe is The end extends into the photocatalyst solution, and several spray heads are connected to the top of the circulation pipe.

Preferably, an ultraviolet lamp is fixedly connected to the inner wall of the casing.

Preferably, a purifier is provided at the top of the housing.

Preferably, a dry humidity measuring device is provided on the outer wall of the housing.

Preferably, a gas outlet is provided on the top of the housing, and a valve is provided at the gas outlet.

Compared with the prior art, the beneficial effects of the utility model are as follows:

The utility model has simple structure and reasonable design. The photocatalyst solution is circulated and sprayed by the circulation pump, and the chemical reaction is stimulated by the ultraviolet lamp arranged on the upper side of the inner wall of the casing, and the formaldehyde in the intake air is oxidized and removed, and the air in the photocatalyst solution in the casing The first oxidation to remove formaldehyde is completed from bottom to top in the environment, and then the formaldehyde air is oxidized to remove formaldehyde in the gaseous environment through the action of the circulating pump and the spray head, and finally the intake air is purified three times through the purifier, which greatly reduces The content of formaldehyde in indoor air.
