Description

Wet type oil and smoke cleaner cleaning solution partly filters the absorption degreaser

The utility model is a kind of wet type oil and smoke cleaner degreaser that can be used for the purification of cooking fume mist, also can be used for civilian smoke exhaust ventilator.

In catering trade oil and smoke cleaner, following five kinds of clean oil smog forms are arranged usually: Mechanical Method, electrostatic method, filtration method, wet method, composite algorithm, they respectively have pluses and minuses, and Mechanical Method does not have use value because efficient is very low; Electrostatic method, filtration method efficient are higher, but investment, take up an area of very greatly, safeguard inconveniently, only in the large-scale catering trade use are arranged; Existing wet method, invest, take up an area of less, but there are secondary pollution or washing medicament formulation problems, in actual use, just need change water or add cleaning solution every very short a period of time, change water and cause secondary pollution, the necessary equipment unit of providing of cleaning solution feed flow is provided, it is a lot of that maintenance cost is increased, difficult the popularization; Composite algorithm is the combination of going up several cleanup forms, also has the problems referred to above.

In civilian smoke exhaust ventilator, because cost and maintenance issues, people just with the discharging of oil smoke mist low latitude, avoid the direct harm of oil smoke to oneself.

For overcoming catering trade oil and smoke cleaner the deficiencies in the prior art, the purpose of this patent is: provide a kind of make wet type oil and smoke cleaner non-secondary pollution, cheaply, the degreaser of easy care, and make it not only can obtain promoting in the catering trade, also can be used for opening up the commercial market of oil and smoke cleaner, change our environmental aspect.

Describe below in conjunction with accompanying drawing 1 pair of technical solutions of the utility model, content, the course of work:

Accompanying drawing 1 is overall structure figure of the present utility model;

For reaching above-mentioned purpose, the technical scheme of this patent is (seeing accompanying drawing 1): on catering trade wet type oil and smoke cleaner device, be equipped with by distribution plate 1, control lever 2, oil spill pipe 3, visual mirror 4, oil discharge pipe 5, filter vat 6, liquid back pipe 7, filtering collector 8 and form, the device that deoils and purify at the part cleaning solution, this device be used for to cleaning solution filter, processing is deoiled in absorption, buoyancy layering, removes the oil content in the circulating fluid.In the wet type oil and smoke cleaner, be between gas cleaning 10 and cyclic water tank 9 devices.

Be embodied as: distribution plate 1 is made up of upper and lower dish, is placed on the filter vat 6, and control lever 2 is made up of the upper end body of rod and lower end ball float, has tank on the body of rod of upper end, and body of rod lower end is connecting ball float, and the body of rod is inserted in the middle part of distribution plate 1, and ball float is placed in the filter vat 6; Bottom at distribution plate 1 is equipped with oil spill pipe, be equipped with filtering collector 8 in the inside of filter vat 6, be equipped with oil discharge pipe 5 and visual mirror 4 on the top of filtering collector 8, be equipped with liquid back pipe 7 in the inside of filter vat 6, its outer end is outside bucket, and be higher than the last plane of filtering collector 8, inner in bucket, and below filtering collector 8.

Its course of work is: the cleaning solution of collecting by gas cleaning 10 is coiled in going up of distribution plate 1, and flow to the bottom by the tank of control lever 2, when the liquid of filter vat 6 is expired, ball float is subjected to buoyancy, driving control lever 2 moves upward, after crossing the tank bottom line, cleaning solution flows to the lower wall of distribution plate 1 by tank, and flows to cyclic water tank 9; When filter vat 6 less than the time, flow to the inside of filter vat 6 by tank, liquid passes through filtering collector 8 after the absorption of a filtration adsorption cycle inner filtration, enter in the cyclic water tank 9 by liquid back pipe 7, when oil slick reaches certain position, discharge by oil spill pipe 3 automatic overflows, when oil emulsion runs up to a certain degree, go out by visual mirror 4 procuratorial work, Open valve is discharged by oil discharge pipe 5, and high liquid level (HLL) is by control lever 2 controls in the filter vat 6, and minimum level is by liquid back pipe 7 controls, because minimum liquid level is higher than the upper surface of filtering collector 8, so the sticking filtering collector 8 that stops up of doing of oil can not occur; This course of work has realized in a working cycles, have only the part cleaning solution can enter in the filter vat 6, and in a filtration adsorption cycle, be cleaned, this part liquid accounts for about 1/3rd of total liquid volume, and this is that the situation of deoiling is adsorbed in a kind of part filtration.

Filtering absorption principle below in conjunction with the filtering collector in 2 pairs of the utility model of accompanying drawing 8 describes:

Accompanying drawing 2 is filtration absorption schematic diagrames of filtering collector 8;

Filtering collector 8 is made up of the material of adsorbed oil, and has certain voidage; It is oil and the oil emulsion in the adsorbed water effectively, makes liquid obtain filtering, and adsorption efficiency is very high, but after absorption was saturated, the rate of filtration is decline rapidly; During its saturation state, adsorption process sees that accompanying drawing 2:11 is an oil molecule, and 12 is hydrone, and 13 is sorbing material; When oil molecule 11, when hydrone 12 enters filtering collector, on the filtering collector 8 aqueous solution is arranged, part oil molecule 11 is arranged under buoyancy function, on float to liquid surface; Gap at two sorbing materials, middle absorption affinity minimum, but also be enough to adsorb oil molecule 11, the oil molecule 11 power minimum that suffers restraints herein, when liquid increases on filtering absorber 8, oil molecule 11 is subjected to buoyancy and increases, and when greater than absorption affinity, liquid just can float oil molecule 11, simultaneously, hydrone 12 enters, and to 11 effects of second oil molecule, successively oil float is risen, the oil molecule 11 that enters with water will be adsorbed, fill up in oil molecule 11 positions of just floating, subsequently, floated by next hydrone 12; By control sorbing material voidage, guarantee absorption affinity that sorbing material produces at gap location desorption power, less than minimal buoyancy greater than oil emulsion; Minimal buoyancy goes out that oil discharge pipe 5 is minimum unloads pasta and the control of filtering collector 8 upper surface drops, can adjust by the installation site, countless hydrones 12 obtain filtering by filtering collector 8 like this, after liquid is purified, enter cyclic water tank 9, participate in circulation next time.

This viscosity and the filter type formed jointly of the adsorptivity of sorbing material by oil, very high on efficient, it is few with the amount that the increase of oil content reduces, in this way, make water and oil emulsion obvious layering occur, oil emulsion is on filtering collector 8 tops, and the water after the purification is in the bottom.

Owing to store in the filtering collector 8 certain amount of fluid is arranged, it can not filter adsorption cycle and reach one to two day usually because of whole gas cleaning process stops to filter absorption; Because liquid scrubbing enters the oil of cleaning system in one-period, much smaller than filtering detergent power in the absorption one-period; So the content of oil has a maximum in whole circulation liquid, maximum equal one filter total oil mass of entering cleaning system in the adsorption cycle, divided by filtering adsorption efficiency, accounting for the ratio of whole liquid volume divided by liquid on the filtering collector 8 again.This maximum can be filtered adsorbance adjustment by dispense liquid, and maximum oil content is less, generally can satisfy under certain purification efficiency, less than the maximum requirement that allows oil content of circulating fluid; So the accumulation problem of oil can not appear in whole cleaning system.Use this device, liquid is circularly purifying oil smoke mist for a long time.

In addition, because hot flue gas is taken away part steam, need regularly add water.

In whole system, because the circulation cleaning water consumption is less, is used for part and filters the adsorption liquid scale of construction still less, it is very slow to add the rate of filtration; So the filtrate root is few, volume is less; Non-secondary pollution, low cost, easy care performance have been guaranteed.It is rising to be used for the cooking fume purification, and is expected to promote on the commercial market.
