DE10055330A1 - Filtering method and appliance incorporate air currents in tubular casing, collector receptacle, pump, ventilator and circulatory system. - Google Patents

Abstract

The method and appliance air currents (4,8) preferably containing fatty and oily particles are contained in a tubular casing (1) with resistance impedances and inserts for wetting by means of emulsion fluid so that they lose their adhesive force. The particles pile up in the collector receptacle (18) above the emulsion (17) and can be discharged in a container. The circulation system is maintained by a pump (20) to prevent the addition of dirt particles. A ventilator (2)creates a vacuum for pulling the air current inwards from the outside,

Description

Cooking fumes from kitchens, roasters and the like from the catering and Hotel industry, including the entire food industry and also tanneries have enormous smell problems.

The conventional filter industry tries to tackle these odor problems to get a grip on minor success. The filters settle after a short time Production times too and are supposed to be disposed of according to the special waste regulation become. This is a huge cost factor and therefore only becomes a filter change if the fully dirty filter has no exhaust air lets more outside.

According to the new VDI 6022, more filters have to be changed for health reasons this means higher costs for air purification for the operators.

The filter system can be a new filter and air treatment process Continuous cleaning eliminates odors and the cleaning process never gets clogged. The filtering process never needs to be changed, just the cleaning liquid must be added every quarter.

This cleaning liquid ( 19 ) placed in a collecting container ( 18 ) is continuously provided by means of a pump ( 20 ) via a membrane ( 11 ) and a distributor sieve for the sucked-in air stream ( 10 ) for forced wetting.

This special emulsion consisting of water and a small addition of ESTE LENSEX 15 VP 1817 as a soft cleaner removes the adhesive force of the dirt develops small active foam bubbles that support the cleaning process and work on odor removal.  

The air flow ( 10 ) leads the forced-wetted air over a double perforated plate basket ( 8 ) which in turn separates the contacted pollutants from the foam bubbles of the emulsion due to its small perforation.

The built-in funnel casing ( 7 ) forces the air flow ( 10 ) through the double-perforated sheet basket ( 8 ), with the condensed emulsion water with the dirt particles returning to the collecting container ( 18 ) with the dirt particles via the pipe drain ( 3 ) on the outer wall ( 1 ) of the pipes ,

For vertical application of the method of the hopper (7) acts as a collector Kon fed into action and leads the liquid over the processes (9/15) back into the collecting vessel (18).

The built-in fan ( 2 ) sucks the air flow ( 4 ) from the outside back in through the perforated sheet jacket ( 8 ).

When the air flow ( 4 ) enters the fan ( 2 ), the remaining moisture is thrown onto the outer casing of the fan, so that this residual moisture can be included in the emulsion circuit as water drops.

The different weight units from fats, oils etc. to the emulsion, the lighter liquid part will always be above ( 17 ) the emulsion limit.

Automation of the feed of the emulsion and overflow of fat + oils in a transport vessel is to be accomplished using limit switches.

Claims (8)

1. The method characterized in that air streams ( 8 + 4 ) are preferably loaded with greasy and oily particles before, these in a tube jacket ( 1 ) with inserted bypasses and inserts ( 8 ) by means of forced wetting ( 11 ) by an emulsion liquid, their Losing adhesive power and in the collecting container ( 18 ) above the emulsion ( 17 ) layers ( 16 ) and then this can be disposed of in an container via an overflow, this circulation system is maintained by means of a pump ( 20 ), so that a clogging of dirt particles on the forced wetting ( 8 + 12 ) is prevented. 2. Device according to claim 1 sketch III page 5 that by displacing the perforated plates in the body shell ( 8 ) from the inside to the outside by a hole or box height, an oblique air flow ( 10 ) arises due to negative pressure, so that on the back ( 21 ) of the The inside of the body of the vacuum creates a vortex, whereby dirt particles ( 22 ) from fats + oils settle, then grow and, after a certain size, they are entrained by the air flow ( 10 ) and thus reach the outside air flow ( 10 ). 19 ) are dissipated. 3. Device according to claim 1 sketch I + II sheet 3 + 4 this funnel shape ( 7 ) the air flow ( 10 ) at negative pressure in the housing ( 1 ) in oblique air flow ( 10 ) through the body jacket ( 8 ). 4. Device claimed in that the fan ( 2 ) generates negative pressure and thus pulls the air flow ( 4 ) from the outside to the inside. Characterized in claim 5. The device taken that, in horizontal or vertical position sketch of I + II, the dirt-laden emulsion (19) can be (3/9/15 /) derived through the processes. 6. The method claimed in that due to the addition of ESTE Lensex Softreiniger 15 VP 1817 into the circulating water an Emul sion in this regard arises from micro-foam formation and large ab separation of oils and. Greases including all dirt particles and smells has proven particularly useful in large exhaust systems. 7. The method claimed that this type of exhaust air purification can be used in a horizontal or vertical version can. The installation can also be used in the bypass process. 8. The device is claimed in that the collecting container ( 18 ) should preferably be higher in dimension than in width. Thus, the superposed lamination (16/17) of emulsion and separating liquid (fats oils +) to separate.
