Abstract

The invention discloses an air filter which comprises an air filter body and a water cup located at the lower portion of the air filter body. A drainage valve is arranged at the bottom of the water cup. An air inlet and an air outlet are formed in the side portion of the air filter body. A filter element is arranged inside the air filter body. The filter element and the filter body are concentrically and fixedly connected through a locking bolt. A flow guiding plate is arranged at the upper portion of the filter element. An umbrella-shaped water baffle is arranged below the filter element. The exterior of the water cup is surrounded by a protective cover. The filter element is a cylindrical filter paper cylinder with continuous folds and constant-amplitude wrinkles. The filter element is composed of two filter paper layers and a catalyst layer clamped between the two filter paper layers. The air filter can effectively filter away substances such as PM2.5 in gas and decrease the content of chemical substances mixed in air.

Description

A kind of air cleaner

Technical field

The present invention relates to technical field of air purification, particularly relate to a kind of air cleaner.

Background technology

In pneumatics, air cleaner, pressure-reducing valve and oil sprayer are called pneumatic three-major-items.Often these three kinds of source of the gas treatment elements being fitted together in order for obtaining several functions, being called pneumatic triple piece.Filter for gas source purification, reduce pressure and lubrication is provided.

The erection sequence of three-major-items is followed successively by air cleaner, pressure-reducing valve, oil sprayer by airintake direction.Three-major-items are indispensable compressed air source units in most pneumatic system, being arranged on gas equipment nearby, is the last guarantee of compressed air quality, its design and installation, except guaranteeing three-major-items sole mass, also to consider to save space, operate easy for installation, the factor such as can be combined.

Containing excessive steam and oil droplet in source of the gas compressed air out, also have solid impurity, as iron rust, the grains of sand, seal for pipe joints agent etc., these can damage piston packing ring simultaneously, small de-air hole on blocking components and parts, shortens the service life of components and parts or makes it to lose efficacy.The effect of air cleaner is exactly the aqueous water in compressed air, liquid oil droplet are separated, and dust in elimination air and solid impurity.

In addition, because compressed air is from air, and inevitably containing various impurity in air, the gaseous impurities such as such as haze, nitrogen oxide, oxysulfide, described impurity can produce damage to equipment and some other vitals.And existing air cleaner only adopts filter core to realize physical filtering, the nitrogen oxide and oxysulfide that are mixed with in PM2.5 particle and air effectively can not be removed.

Summary of the invention

The object of the invention is to propose a kind of air cleaner, the haze in compressed air, nitrogen oxide and oxysulfide can be made to be processed into the state can anhydrated and dissolve and remove, be beneficial to follow-up equipment and remove.

For reaching this object, the present invention by the following technical solutions:

A kind of air cleaner, comprises air cleaner body and is positioned at the water tumbler of body lower part, be provided with draining valve bottom water tumbler; The side of air cleaner body has air intlet and air outlet slit; air cleaner body interior is provided with filter core; be fixedly connected with concentric to filter core and filter body by clamping screw; filter core top is provided with deflector; below is provided with umbrella shape water fender, the outside protected cover institute of water tumbler around.

Described filter core is that the cylindrical shape of continuous catadioptric constant amplitude gauffer filters paper web, and it is made up of two layers of filter paper layer and the catalyst layer be mixed between two layers of filter paper layer.

Described filter paper layer is glass fiber filter paper layer, particularly preferably ultra-fine fibre glass filter paper layer.

The catalyst that described catalyst layer adopts comprises following component,

A) the titanium base iron cerium molybdenum vanadium oxides composite of 6%-20%, the mol ratio Ti:Fe:Ce:Mo:V of its each component is 1:(0.05-0.1): (0.05-0.1): (0.05-0.1): (0.05-0.1);

B) ferric vandate of the zirconium doping of 3%-8%, Zr:FeVO ₄mol ratio be (0.02-0.2): 1;

C) active carbon of surplus.

The preparation method of described catalyst can take conventional infusion process and other alternatives, the prior art unrestricted choice that those skilled in the art can grasp according to it, and the present invention repeats no more.

From the compressed air that air cleaner import flows into, be introduced into deflector 2, deflector there is the helical teeth of equally distributed similar electric fan, swiftly flowing compressed air is forced to produce strong rotation along the tangential direction of tooth, mix aerial aqueous water oil and larger impurity separate under powerful centrifugal action, be thrown on the inwall of water tumbler 7, flow to the bottom of water tumbler.The compressed air of removing aqueous water oil and larger impurity, again by the further filtration of filter core 3, remove small solid granulates, simultaneously, the catalyzed oxidation when passing catalyst layer of nitrogen oxide in air, oxysulfide, be converted into removable soluble compounds, be mingled with in air and the aqueous water condensed out dissolves and then removes, export clean compressed air from outlet.Water tumbler is separated into upper and lower two parts by umbrella shape water fender 5, and bottom keeps pressure dead zone, the water oil at the bottom of can preventing the air-flow of High Rotation Speed to pick up glass.Water oil at the bottom of being gathered in glass bleeds off from draining valve 8.

The present invention adopts ultra-fine fibre glass as the material of air cleaner filtration core, effectively can filter out the PM2.5 particle in air, simultaneously, catalyst layer generation catalytic oxidation in filter core, this catalytic oxidation is because the synergy between catalyst unique ingredient, PM2.5 particle can be purified completely, and make nitrogen oxide, chance that oxysulfide is converted and then removes improves.
