DE3018677A1 - Smoke purifier esp. for large kitchens - has cylindrical cooling shell tangential smoke inlet at top and bottom outlet - Google Patents

Abstract

A smoke or fumes purifier is intended esp. for removing the odours from air discharged from a meat-roasting or fish-smoking plant or a large kitchen. The purifier consists of a vertical cylindrical vessel, in which the fumes enter tangentially at the top, spiral downwards at high speed so that they are cooled by the cooling jacket in the wall of the vessel and leave at a bottom pure air outlet. Droplets charged with the odoriferous and other substances are collected at the bottom in a vessel.

Description

Description and explanation of the patent and auxiliary

utility model registration 'raw gas cleaning device for exhaust gases in Smokers and large kitchens'.

It is known to purify the exhaust gases from smokers, preferably in butcher shops and fish fryers, through dry chemisorption packages, Make electrostatic precipitators and / or washing devices.

The odor pollution is sometimes very strong and leads to neighbors Complaints.

For this reason, in recent times it is often the case that a Smoking device or the creation of a large kitchen just with gas cleaning possible.

In many cases, the exhaust gases are heated up to over 8000, to burn the odorous pollutants.

However, heating up to 8000 is very energy-intensive.

It is already known in large-scale plants by cooling the Gases to achieve precipitation, e.g. of tar-containing odorous substances.

This generally requires very large heat exchange surfaces.

According to the invention it is therefore proposed to choose a device in the high speed, preferably in a tubular annulus, through tangential Introduction the gas is brought into a rotary motion and it is briefly supercooled so that the odor-bearing pollutants such as

Drip out tar-containing substances or substances containing wood-vinegar and the cleaned gas can be discharged through the chimney.

In the accompanying drawing, Fig A, is shown: with (1) the Raw gas inlet with (2) the raw gas outlet with (3) the cooling jacket with (4) the pollutant collecting pot In Fig B it is shown: with (1) the raw gas inlet into the radial space with (2) the Clean gas outlet.

This measure according to the invention is tangential with high Speed of raw gas entered into an annulus, which is supercooled, which condensed Liquid with the odorous substances is separated without, as in the case of large-scale plant technologies, Drip catchers and fillers must also be used.

Of course, the invention is not limited to the above in detail Forms of training shown and described are limited, but there are numerous Changes possible without deviating from the basic idea, raw gas, the is provided with odorous pollutants, tangentially at high speed to introduce into a hypothermic body, so that the pollutants through the hypothermia are condensed out and introduced tangentially by the high speed Amounts of gas enlarge and drip off the droplets that form on the walls, wherein the gas according to the invention in the flow direction of the droplet separation from above is carried down.

Claim:

Claims (1)

Claim: Flue gas cleaner for the removal of preferably Odor substances behind preferably meat and / or fish roasters in butcher shops and large kitchens, characterized in that the raw gas to be cleaned is tangential at the top at (1) introduced into a preferably tubular body at high speed is and the gas is cooled on the cooling jacket (3) and preferably in a rotary motion to Clean gas nozzle (2) is guided downwards, so that the pollutant-laden ones formed Drops can be collected in a container (4).
