The invention provides an oil fume purifier and a manufacturing method thereof. The oil fume purifier comprises a shell, anode plates and cathode lines, wherein the anode plates and the cathode lines are mounted in the shell; each anode plate takes the shape of an encircled cylinder; one cathode line is positioned at the middle of each cylindrical anode plate; an air inlet and air outlet which are used for oil fume intake and exhaust are respectively arranged in the two ends of each cylindrical anode plate; and the anode plates are formed by spicing folded plates. By adoption of the above structure, the oil fume purifier has the advantages that the uniformity of the electric field strength is good, the structure is stable and reliable, the mounting is convenient, and cleaning dead angles are avoided.

The invention discloses a filter and a purifier equipped with the filter. The filter comprises a supporting frame and a plurality of filtering devices, wherein the supporting frame comprises an upper mounting plate and a lower mounting plate which are separated from each other as well as a plurality of connecting rods between the upper mounting plate and the lower mounting plate; the upper mounting plate and the lower mounting plate are ring-shaped; the connecting rods are circumferentially arranged around the centers of the ring-shaped plates at intervals; a plurality of mounting holes are defined by two adjacent connecting rods, the upper mounting plate and the lower mounting plate; the filtering devices are arranged in the mounting holes separately; and the mounting holes are sealed by the corresponding filtering devices. The filter provided by the invention is simple and compact in structure, and large in purifying area. Meanwhile, different requirements can be met by the filter when the structural parameters of the supporting frame are adjusted, so that the application range of the filter can be broader.

The invention discloses an efficient wall-penetrating-type fresh air purifying device, and belongs to the technical field of fresh air purifying. The efficient wall-penetrating-type fresh air purifying device comprises an indoor face plate, a wall penetrating body, an inner barrel, an outer barrel and an outdoor air-inlet rain cover. The outer barrel is in sliding fit with the inner barrel, and the outer side of the outer barrel is in close fit with the inner wall of a wall hole. An HEPA filter, a low efficiency filter and a full-plastic-packaging axial flow fan are arranged in the wall penetrating body. The HEPA filter is an HEPA folded conical core filter. The HEPA folded conical core filter comprises an HEPA folded filtering conical core, a top positioning disc and a bottom air stopping disc. The HEPA folded filtering conical core is connected with the bottom air stopping disc through hot melt adhesive and connected with the top positioning disc through hot melt adhesive. The diameter of the top of the HEPA folded filtering conical core ranges from 100 mm to 500 mm, the diameter of the bottom of the HEPA folded filtering conical core ranges from 30 mm to 400 mm, and the height of the HEPA folded filtering conical core ranges from 100 mm to 300 mm. A circular air hole is formed in the middle of the top positioning disc, and the diameter of the circular air hole ranges from 70 mm to 470 mm. The efficient wall-penetrating-type fresh air purifying device has the beneficial effects of being low in density, small in air resistance, large in air volume, long in service life, low in cost and ideal in dust removal effect.

The invention discloses a high-power plasma gas purification device, which belongs to the technical field of gas purification. The gas purification device comprises: a metal shaft and a metal electrode sleeved on the metal shaft, the edge of the metal electrode forms a circumferential linear discharge surface, an insulating medium cylinder is arranged outside the metal electrode, and the insulating medium cylinder is also A metal grounding shell is provided; the metal electrode is connected to the high-voltage pole of the high-voltage power supply through the metal shaft, and a grounding port is drawn out of the metal grounding shell to connect to the grounding end of the high-voltage power supply. The gas purification device of the present invention can increase the discharge power on the basis of increasing the discharge area, generate more plasma active components, and improve the purification efficiency of the gas to be treated.
