Abstract

The utility model provides a combined type oil fume filtering and purifying device, comprising a three-stage purification composed of a water-mist water-diaphragm oil fume purifying section, an oil fume separating section and a filtering adsorption section. Wherein, the structure of the separation zone in an oil fume separator is the venturi tubular structure which is pressed and combined by a high-strength ultrathin aluminum alloy. Each two sets of the used media with the smooth surfaces are assembled, and are formed the inner cavity of the smooth vortex labyrinth. The arranging mode of the filter material in the filtering adsorption section is the vertical arrangement, and a collecting tank is arranged on the bottom of the device. The utility model adopts the side-inserting structure, and the whole device is composed of a frame and a filter element in the form of the drawer. A plurality of oil removing mechanisms are integrally used to combined the condensing coagulation function, the cloth filtering function, the inertial impaction function, the liquid absorbing and purifying function, the alkaline oil removing function and the smell removing function to the oil fume. Thus, the discharge concentration of the oil fume and the water passing quantity of the oil fume are decreased, the purification efficiency of the oil fume is effectively raised, and the pollution of the oil fume to the urban environment is reduced.

Description

The composite oil smoke filtering and purifying

Technical field

The utility model relates to a kind of purifier for filtering oil smoke, particularly relates to a kind of composite oil smoke filtering and purifying that is used for the gas disposal of catering trade cooking fume, belongs to the air filtration purification techniques, is suitable for installing and using at public kitchen.

Background technology

At present, to the processing of catering trade cooking fume gas, the technical measures and the corresponding apparatus of more existing both at home and abroad improvement: i.e. filtering type fume purifier of fume, water film type fume purifier of fume, honeycomb fashion fume purifier of fume and electrostatic fume purifier of fume etc.Because kitchen institute oil extraction mist contains the ternary material of gas, liquid, solid simultaneously, it is all very big that the sort of method captures the material viscosity of getting off, and for example adopts electrostatic precipitation and filter plant to exist effective acting time long and clean pole plate difficulty, the problem that operating cost is high; Inertial separation equipment clean efficient is low; Washing facility is handled oil smoke efficient Gao Yike and is removed smell, but need auxiliary equipment such as water pump, tank, cause the operating cost height, add the mist of oil that purifies and sink to off-odor and the waste liquid secondary pollution problem that the pond deposition produces, make its use that certain limitation be arranged, can not fundamentally solve the oil smoke governing problem.

The utility model content

The purpose of this utility model is to overcome the prior art above shortcomings, improve by research, provide a kind of composite oil smoke filtering and purifying, this device is set up on water smoke water film type fume purifying basis, and the multiple oil removing mechanism of integrated use, after oil smoke carried out the effect of condensation coalescence, fabric filtration, inertial collision, liquid absorption cleaning, alkaline degreasing and go compound actions such as flavor, reduce the concentration of emission of oil smoke, the water amount of oil smoke, improve the purification efficiency of oil smoke effectively, alleviate the pollution of oil smoke urban environment.

The technical solution that the utility model provides is: this composite oil smoke filtering and purifying includes a water smoke water film type fume purifying section, be characterized in also including the oil smoke segregation section that contains efficient absorption liquid and oil smoke mixture and the filtration adsorption section of an acceptance from water smoke water film type fume purifying section, the structure of the Disengagement zone in the oil fume separator in the wherein said oil smoke segregation section is the venturi tubulose structure by high strength slim aluminium alloy compression moulding combination, the per two groups of combinations of used medium with smooth surface, and form the inner chamber of smooth eddy current labyrinth-like; The arrangement of the filtrate in the described filtration adsorption section is provided with feeder for vertical layout and in device bottom.

For realizing the purpose of this utility model better, the filtrate arrangement form in the described filtration adsorption section is a folded form air-flow arrangement, and the filtrate arrangement form also can arbitrarily change certainly.

For realizing the purpose of this utility model better, be convenient to the maintenance and the replacing of product, this composite oil smoke filtering and purifying has adopted the other structural shape of inserting formula, outfit of equipment is a framework, be provided with the filter element that is made for the drawer form in the framework, on the framework inboard, be provided with slideway, be provided with feeder, on framework, also be provided with vertical throttle-type demist, remove oil baffle in the framework bottom.

Compared with prior art, the beneficial effects of the utility model are:

1. consider the oil smoke that enters in this composite oil smoke filtering and purifying, be in hydro-vent with biphase gas and liquid flow after water smoke, moisture film fully contact, certain water amount is arranged, the arrangement of filtrate adopts vertical the layout, and in device bottom feeder is set, with traditional filtrate uprush arrangement mutually million, be consistent in the filtrate packing density, under the constant situation of purifying property, resistance has reduced 2.5 times, and the trend that the filtering layer resistance increased with running time is also less.

2. oil fume separator structure and shaped design thereof have overcome the shortcomings that clearance is low, the clean and maintenance cycle is short such as common metal weaving guard, grid, upgrade and the otherwise effective technique processing by material-structure, prolong the clean and maintenance cycle greatly, improved purification efficiency.

3. for ease of the maintenance and the replacing of product, this composite oil smoke filtering and purifying has adopted the other structural shape of inserting formula, is made by galvanized steel plain sheet, and weight is lighter, is convenient to installation and maintenance, also is convenient to the replacing of filtrate.
