Abstract

The utility model relates to a purifier for kitchen oil fumes, which is composed of a casing, an oil filtering core and an oil receiving box, wherein, the oil filtering core (2) is composed of a plurality of smooth and parallel curved plates (4). Spacing rings (5) with the thickness from 2 mm to 20 mm are arranged between the curved plates (4), the periphery of the oil filtering core (2) is surrounded by the casing (1) and the oil receiving box (3) of the bottom to form a sealing channel, and the casing (1) and the oil receiving box (3) are connected with a fume exhausting duct by a flange. The utility model has the advantages of larger surface area of contact adsorption, strong turbulence degree of the airflow, good separating effects, high oil fume purifying rate which is more than 90%, good waste oil collecting modes, convenient treatment of the collected waste oil, difficult secondary pollution, simple structure, low cost which is only 10% of the cost of electronic similar products and 30% of the cost of wet mechanical composite similar products, low manufacture process requirements and convenient installation.

Description

A kind of cooking fume cleaner

Technical field

The utility model belongs to the waste gas purification technology, and specifically, it relates to a kind of cooking fume cleaner.

Background technology

The cooking fume cleaner that generally adopts both at home and abroad has electronic type, mechanical type, wet type and combined type multiple at present.

Because oil smoke gas is formed complicated, oil smoke composition in the oil smoke gas effectively to be separated, collects and do not cause secondary pollution, exist the difficulty of each side, so all at present cooking fume removers are from effect, life-span, cost and prevent that the secondary pollution aspect from seeing all not ideal enoughly, the common drawback of the general various cooking fume removers of existing shape that conclude is: effect is bad, the life-span is long, easily cause secondary pollution, complex structure, involve great expense.The absorption cooking fume remover of particle for example, because the surface area of particle is big, can effectively the oil smoke composition in the exhaust be adsorbed, but this kind device does not have effective measures to make oil smoke and particle separation and collects, the state of reaching capacity can not continue to separate oil smoke and die of old age soon.And for example wet lampblack depuration equipment is a water curtain of arranging certain area on the passage of smoke evacuation, and oil smoke is taken away by moisture film absorption, because the water curtain area is limited, effect is bad, and for the circulatory system of arranging water makes structure very complicated, the processing of greasy dirt addle easily causes secondary pollution.And for example the electronic type cooking fume remover also is that structure is very complicated, cost more than 20,000 yuan and effect bad.

Summary of the invention

The purpose of this utility model is to provide a kind of good separating effect, simple in structure, low cost, easy for installation, non-secondary pollution, is applicable to the cooking fume remover that big cafeteria, dining room and family kitchen are used.

The utility model adopts following technical measures to implement: cooking fume cleaner is made of shell, oil filter element and swab case, it is characterized in that: described oil filter element is made of some smooth, parallel curved slabs, be provided with the spacer ring that thickness is 2-20mm between each curved slab, surround by the swab case of shell and bottom around the oil filter element and form seal channel.

Above-mentioned described shell can link to each other with smoke discharging pipe by ring flange with swab case.

Core component oil filter element of the present utility model is to constitute the narrow upright bent road of folder by tens of smooth parallel curved slabs.This kind structure has three big characteristics: one has the contact adsorption surface area that reaches several square metres; They are two years old, bent road is divided into tens of roads with the oil smoke air-flow and presss from both sides narrow air flow stream, it swings tangential motion forward along bent road, produce centrifugal force, make air flow stream obtain abundant disturbance and form strong turbulent flow, with the oil film mixing and absorption on the bent road wall, they are three years old, upright bent road has utilized the characteristics of oily flowability and permeability and kitchen intermittent duty, and the lip-deep oil film in bent road is flowed under the gravity effect in the oil collection box of bottom automatically, and collected waste oil disposal is convenient maybe can be made fuel or make industrial chemicals.The utility model and existing general cooking fume remover relatively have the following advantages:

1. the contact adsorption surface area is big, and stream turbulence is strong, good separating effect, and the fume purifying rate is up to more than 90%.

2. the waste oil collection mode is good, and the waste oil of collection is convenient to handle, and is difficult for causing secondary pollution.

3. simple in structure, cost is low, is 10% of electronic type like product only, is 30% of wet type mechanical type combined type like product.

4. manufacture process requirement is not high, and is easy for installation.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

The major part 4 that constitutes oil filter element adsorbed oil hood is smooth streamlined curved slabs, each oil filter element uprightly is arranged in parallel by tens of curved slabs, constitute the oil smoke contact adsorption surface area that reaches several square metres, connect the location by bolt 6 spacer rings 5 between each curved slab, the effect of spacer ring 5 is the gaps between the control curved slab, the size of this gap is determining the quantity of curved slab, i.e. the size of oil smoke contact adsorption surface area and the size of flow resistance.Curved slab is upright, and when smoke evacuation system was out of service, the oil film on the curved slab flowed into bottom oil collection box 3 automatically under the gravity effect.Have 7 gas block panels 7 evenly to distribute (Fig. 3) in the oil collection box 3, its effect is to avoid smoke discharging short circuit in oil collection box.Every gas block panel bottom center has an oil-through hole 11, flows out so that the waste oil in the oil collection box can focus on oil-out 8.

Oil filter element 2 places the encirclement of shell 1 and swab case 3, and shell has ring flange to be connected (Fig. 4) with smoke discharging pipe 9 with the oil collection box periphery.12 is exhaust fans for kitchen use among Fig. 5, the 10th, and the movable sheet of the rain that keeps out the wind.13 is household smoke exhaust ventilators among Fig. 6.

Claims

1. cooking fume cleaner, constitute by shell, oil filter element and swab case, it is characterized in that: described oil filter element (2) is made of some smooth, parallel curved slabs (4), be provided with the spacer ring that thickness is 2-20mm (5) between each curved slab (4), surround by the swab case (3) of shell (1) and bottom around the oil filter element (4) and form seal channel.
