Abstract
The utility model provides a preliminary treatment wind channel, plasma electric field wind channel refers to plasma electric field wind channel entry, set up dirt water cushion on the tangential wind face of fan blade, this fan is installed in the air current entrance of clarifier plasma electric field, and steam and large granule dust in the air current can be adsorbed to the fan rotation to the effect of air-purifying has been improved.
Description
Technical Field
The invention relates to a plasma air purification device, in particular to a device for removing moisture and dust at an air flow inlet of an air duct of a plasma air purifier.
Background
In the existing synthetic kitchen (application number: 2019102886680.0), there is no device for removing dust and water vapor at the entrance of plasma air duct for removing oil smoke, so that the oil smoke with dust and water vapor directly impacts the electric field of the plasma purification device, part of the dust in the oil smoke will adhere to the positive and negative plates of the purification device, the dust will be accumulated on the plates more and more thickly, and the water vapor flowing through the electric field of the plasma air purification device will be unfavorable to the electric field, and will short-circuit and leak electricity, and will cause the device damage, and as a result, the air purification treatment will be greatly reduced, and the effect of plasma air purification will be directly influenced.
Disclosure of Invention
In order to overcome the defect that the airflow wrapped with the miscellaneous dust and the moisture directly impacts the plasma electric field, the invention provides a pretreatment air channel which comprises a plasma electric field air channel, a fan and a water-facing groove, wherein a dust water cushion is arranged on the tangential surface of fan blades of the fan, the fan is arranged at the air flow inlet of the plasma electric field of a purifier, and the fan can adsorb the moisture and large-particle dust in the oil smoke airflow when rotating, so that the effect of plasma air purification is improved.
The technical measures adopted for solving the technical problems are that the plasma electric field air channel refers to an inlet of the plasma electric field air channel, the fan adopts a cross-flow fan, the fan is arranged at an air flow inlet of a plasma electric field of a purifier in a synthetic stove, bearings at two ends of the fan are arranged on shells at two ends of the air flow inlet of the plasma electric field, a layer of dust water cushion is covered on a wind cutting surface of a fan blade of the fan, the dust water cushion is rough in surface and has water filtering performance, the dust water cushion can adsorb impurity dust and water gas wrapped in the air flow, in order to avoid air flow saturation on the dust water cushion, an air hole is formed in a blade of the fan, and a part of air flow can pass through the dust water cushion and pass through the air hole, so that the effect of the dust water cushion for filtering the impurity dust and the water gas is further improved; the wall surface of one side of the purifier shell is provided with an interlayer corresponding to the windward side of the fan, the inner wall of the interlayer on the windward side is provided with a plurality of water-facing grooves, and the water-facing grooves are communicated with the interlayer. When the purifier works, the fan starts to rotate, part of the foreign dust and water vapor wrapped in the air flow can be adsorbed by the dust water cushion on the fan blade, and the water vapor is condensed into water on the dust water cushion and then thrown out by the centrifugal force of the fan blade, carries the foreign dust to be thrown into the water receiving groove on the side wall and flows downwards into the dust collecting disc from the interlayer. The air flow wrapped with the foreign dust and the moisture is prevented from directly impacting the electric field of the plasma purifier, the effect of filtering the foreign dust and the moisture by the fan blades is achieved, and the purpose of purifying the air by the purifier is improved.
The invention has the advantages that the adsorption treatment can be carried out on part of the dust and the water vapor which are wrapped in the air flow before the air flow enters the electric field, and the structure is simple.
Drawings
The invention will be further explained with reference to the drawings.
FIG. 1 is a schematic view of a preconditioned air duct blower.
FIG. 2 is a schematic view of a pre-treatment duct installation location.
