Abstract

The utility model relates to an oil fume filter plate which has a simple structure and fully filters and separates oil fume. The filter plate is composed of a plurality of filter plates with same shapes and structures, and the adjacent filter plates are arranged at intervals in mutually parallel; the adjacent filter plates are arranged in a mode that air holes and air holes are aligned and rib plates and rib plates are aligned forward and backward in a flow direction; when smoke passes through the oil fume filter plate, the oil fume filter plate forms innumerable stable high-speed whirlpools; and in a role of whirlpools, non-air materials in the smoke are gathered to the center of the whirlpools and finally deposited on the filter plates, thereby realizing the purposes for removing oil fume materials in the smoke and cleaning air. The high-speed whirlpools generated by the oil fume filter plate have much quantity, are stable and can fully filter and separate.the oil fume; and the inner part of a cooker hood is not easy to accumulate oil and deposit scale, so that the long-time stable work of the cooker hood is ensured, and the wind pressure loss is small.

Description

Cooking fume filtering plate

Technical field

The utility model belongs to environmental technology field, relates to a kind of cooking fume filtering plate that can effectively separate catering trade, dining room, dining room, family kitchen oil smoke.

Background technology

The existing oil smoke technology of removing mainly is the centrifugal action purifying oil fume that relies on volute blower fan high speed rotary motion to produce, when a large amount of oil smoke enter smoke exhaust ventilator, very easily make the long-pending in a large number oil of machine inner chamber and blower fan, not only clean difficulty, but also can cause the smoke exhaust ventilator operation irregularity, noise increases, and rotating speed reduces, and the smoke pumping effect worse and worse.Therefore, how before flue gas enters blower fan with regard to isolation of purified, become people's overriding concern.

Filtering oil smoke is that present oil smoke enters the main separating measure before the cigarette machine, filtering oil smoke web plate or utilize condensation to separate oil smoke, or adopt and be folded to structure, utilize inertia to separate oil smoke with whirlpool.Because the surface area of screen pack twine is little, little with the contact-making surface of oil smoke, it is limited that it catches the condensation separation effect.It is few to be folded to the whirlpool quantity that structure forms, the washing away of main is whirlpool is subjected on runner high-velocity fluid, and the whirlpool size is little, and life period is short, poor stability, the fragmentation that very easily comes off, its centrifugation is also limited.The utility model integrated application condensation and whirlpool centrifugation come the isolated by filtration oil smoke.

Summary of the invention

For isolated by filtration oil smoke effectively, the characteristic that the utility model provides a kind of applicating fluid to form behind barrier to rotate whirlpool is at a high speed separated the cooking fume filtering plate of oil smoke.This cooking fume filtering plate flue gas by the time form countless stable high speed whirlpools.Under the effect of entrainmenting of whirlpool, the non-air material aggregation in the flue gas is deposited on the filter plate at last to the whirlpool center, removes oil smoke material in the flue gas, the purpose of clean air thereby reach.

The technical scheme that its technical problem that solves the utility model adopts:

A kind of cooking fume filtering plate is characterized in that: the filter plate identical by some shapes, that structure is identical constitutes; Adjacent filter plate is at regular intervals, is parallel to each other; Adjacent filter plate on flowing to by the setting of aliging with the gusset front and back of pore and pore, gusset; Filter plate quantity is more than at least 2 or 2; Pore is shaped as the strip that circle, ellipse, triangle, quadrangle, rhombus, polygon or two ends are circular arc.

The beneficial effects of the utility model are, and are simple in structure, and oil smoke separates fully, good purification, and also air loss is little, is difficult for long-pending oil, incrustation in the smoke exhaust ventilator, guarantees the long-time steady operation of smoke exhaust ventilator.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Among the figure: 1. support 2. gussets 3. pores 4. grooves 5. whirlpools

The specific embodiment

In the embodiment shown in fig. 1, filter is stamped to form by sheet metal, and pore is a strip, and the gusset longitudinal cross-section is circular-arc, the inward at both ends bending, and intermediate groove is beneficial to long-pending oily water conservancy diversion.It is good that the most handy aluminium of sheet metal or alloy material, aluminum material have thermal conductivity, and rapid heat dissipation promotes condensation; And characteristic such as sticking not oily, easy to clean, in light weight, smooth surface.

When mobile flue gas passes through pore, will behind gusset, encircle pore and produce the toll bar whirlpool.Flow velocity is big more, and the rotating speed of whirlpool is big more.The whirlpool of rotation entrainments the whirlpool center with the non-air material in the flue gas at a high speed.Because whirlpool is not subjected to washing away of high-velocity fluid on the runner behind the gusset, difficult fragmentation comes off, good stability, and the time of existence is long.Whirlpool is stable more, and the time of existence is long more, and the non-air material density that vortex core is assembled is high more, and the particulate spacing is more little, and the gathering of the favourable aggregation substance of healing is grown up.The great colloidal particles of viscosity, soot particles, steam, charcoal dirt particulate are under the effect of entrainmenting of whirlpool, and the quantity in vortex core is more and more, and density is increasing.Particulate constantly attracts each other, mutually collision, through pushing repeatedly, being out of shape, cohesion is binded, its quality and size are increasing, at last with big quality particles settling on gusset.Under the certain situation of flow, flow velocity, the ring pore gusset quantity of certain width is many more, and the gusset total length is long more, flue gas by the time will produce the stable whirlpool of greater number, the little whirlpool of generation is also many more, oil smoke separates just abundant more, clean-up effect is just good more.

The whirlpool number that the filter of multilayer produces will be that integral multiple ground increases, and cleaning effect is better.Adjacent filter aligns by before and after pore and pore, gusset and the gusset on flowing to, and what be arranged in parallel is provided with structure, the stablizing of assurance whirlpool.

The parallel filter structure of multilayer has increased the contact area of oil smoke and metal greatly, has also increased collision effect, adhewsive action, settlement action and the condensation of soot particles effectively.Temperature that can very fast reduction oil smoke reaches below " dew point " of oil smoke material, and oil smoke just can be condensed into drop on filter plate, separates from gas, realizes purifying purpose.

Claims

1. cooking fume filtering plate, it is characterized in that: the filter plate identical by some shapes, that structure is identical constitutes; Adjacent filter plate is at regular intervals, is parallel to each other; Adjacent filter plate on flowing to by the setting of aliging with the gusset front and back of pore and pore, gusset; Filter plate quantity is more than at least 2 or 2; Pore is shaped as the strip that circle, ellipse, triangle, quadrangle, rhombus, polygon or two ends are circular arc.
