Tupakkahuone - Rökrum Tämän keksinnön kohteena on tupakkahuone, jossa huoneen ilma 5 on puhdistusjärjestelmän avulla pidettävissä puhtaana siten, että tupakkahuoneesta poistuvan ilman ja tupakansavun sisältämät hiukkaset tarttuvat puhdistusjärjestelmään kuuluvaan suodatinyksikköön, jossa on eurovent-luokiteltu suodatin EU4-EU5, jonka jälkeen on aktiivihiilisuodatin ja esimerkik-10 si kaliumpermanganaatilla kyllästetty alumiinioksidi, joka on laajatoiminen hapettaja ja joka poistaa epäpuhtaudet ilmasta adsorption, absorption ja kemiallisen hapetuksen avulla .The present invention relates to a tobacco room in which the room air 5 can be kept clean by means of a cleaning system so that particles of air leaving the tobacco room and tobacco smoke adhere to a filter unit of the cleaning system with a Eurovent-classified filter EU4-EU5 followed by an activated carbon filter and e.g. 10 Si potassium permanganate impregnated alumina, which is a broad-spectrum oxidant that removes contaminants from the air by adsorption, absorption and chemical oxidation.

15 Ilmassa leijuva pöly, allergiaa aiheuttavat sienet, alhainen kosteus ja bakteerit ovat merkittäviä huoneilman laatua heikentäviä tekijöitä, mutta ainoa näkyvä sisäilman saastuttaja on tupakansavu: nikotiini, polyaromaattiset hiilivedyt (PAH-yhdisteet) sekä savun sisältämät hiukkaset.15 Airborne dust, allergenic fungi, low humidity and bacteria are significant contributors to indoor air quality, but the only visible indoor air pollutant is tobacco smoke: nicotine, polyaromatic hydrocarbons (PAHs) and smoke particles.

Ohjaamalla tupakointi erikoisilmastoituun tilaan suojellaan muita huonetiloja ja ilmastointilaitteita ennenaikaiselta likaantumiselta ja ennen kaikkea suojellaan tupakoinnista kärsiviä henkilöitä.Controlling smoking in a specially ventilated area protects other rooms and air conditioners from premature contamination and, above all, protects those suffering from smoking.

2525

Yksinkertaisin tapa ilmastoida tupakkahuoneita on se, että puhaltimen avulla aikaansaadaan alipainetta huonetilaan ja huonetilassa oleva ilma johdetaan rakennuksesta ulkoilmaan. Talvisaikana tämä on epätaloudellista, koska ulkoilmaan joh-30 detaan samanaikaisesti kallista lämpöenergiaa. Tästä johtuen tupakkahuoneessa oleva ilma on suodatettu ja kierrätetty tupakkahuoneessa tai samassa rakennuksessa.The simplest way to ventilate tobacco rooms is to use a fan to create a vacuum in the room and to direct the air in the room from the building to the outside air. In winter, this is uneconomical because expensive thermal energy is fed to the outside air at the same time. As a result, the air in the smoking room is filtered and recirculated in the smoking room or in the same building.

Keksinnön tarkoituksena on aikaansaada tupakkahuone, jossa 35 on niin hyvä ilmanvaihto, että sen sisäilman puhtausaste on riittävä siellä oleskeleville ja tupakointihuoneen poistoil-ma puhdistetaan niin tehokkaasti, että se voidaan johtaa suoraan ympäröivään huonetilaan ilman, että se kuormittaa 2 92290 liikaa ympäröiviä huonetiloja. Keksinnön mukainen kevytrakenteinen tupakkahuone poikkeaa markkinoilla olevista tupakkahuoneista siinä, että sen poistoilma puhdistetaan myös kemiallisesti. Se eroaa oleellisesti nykyisin jo markkinoil-5 la olevista ratkaisuista siinä, että näissä poistoilman hiukkaset poistetaan vain fysikaalisesti tavanomaisten säh-kösuodattimien avulla. Sähkösuodatusmenetelmän haittapuolena on, että tupakansavun sisältämät kemialliset yhdisteet rikastuvat poistoputkiin ja suodattimiin aiheuttaen ympäröi-10 viin tiloihin jo hyvin lyhyen käyttöajan jälkeen kemiallisia päästöjä, jotka havaitaan hajuongelmien muodossa. Hajuongel-mat poistetaan keksinnön mukaisesti yhteensovitettavien fysikaalisten ja kemiallisten suodatussysteemien avulla. Lisäksi tupakkahuoneelle laaditaan kattava huolto-ohjelma, 15 joka takaa poistoilman laadun säilymisen huoltokustannukset minimoiden.The object of the invention is to provide a tobacco room in which the ventilation is so good that its indoor air is sufficiently clean for the occupants and the exhaust air of the smoking room is cleaned so efficiently that it can be led directly to the surrounding room without overloading 2,92290 surrounding rooms. The lightweight tobacco room according to the invention differs from the tobacco rooms on the market in that its exhaust air is also chemically cleaned. It differs substantially from the solutions already on the market today in that the exhaust air particles are only physically removed by means of conventional electrostatic precipitators. The disadvantage of the electrofiltration method is that the chemical compounds contained in tobacco smoke are enriched in the exhaust pipes and filters, causing chemical emissions to the surrounding premises even after a very short period of use, which are detected in the form of odor problems. Odor problems are eliminated by means of compatible physical and chemical filtration systems according to the invention. In addition, a comprehensive maintenance program is prepared for the smoking room, 15 which ensures that the quality of the exhaust air is maintained while minimizing maintenance costs.

Keksinnön mukaiselle tupakkahuoneelle on tunnusomaista se, että puhdistusjärj es telinään kuuluu hajusuodatin, joka on 20 esimerkiksi kemiallisesti modifioitu polypropyleeni-styreeni -kopolymeeri.The tobacco room according to the invention is characterized in that the cleaning system comprises an odor filter which is, for example, a chemically modified polypropylene-styrene copolymer.

Hajusuodatin perustuu polypropyleeni-styreeni-kopolymeeriin, jolla on kemiallinen kaava: 25 CH3 (-C-CH2-)nThe odor filter is based on a polypropylene-styrene copolymer with the chemical formula: CH3 (-C-CH2-) n

30 (CH-CHr )m- (- CH-CH2-)d = PPST(CH-CH 2) m - (- CH-CH 2 -) d = PPST

Suodatinkoostumuksella on esimerkiksi seuraavat kemialliset muunnokset: li 35 92290 3 PPST -> PPST-SOjH K1 -> PPST-CH2N(CH3) +3C1- Al 5 -> PPST-NHj AK22For example, the filter composition has the following chemical modifications: li 35 92290 3 PPST -> PPST-SOjH K1 -> PPST-CH2N (CH3) + 3C1- Al 5 -> PPST-NHj AK22

Keksinnön mukaisella ratkaisulla, jossa suodatinyksikkö muodostuu edellä mainitusta yhdistelmästä, saadaan kaikki tupakansavussa olevat haitalliset ja myrkylliset partikkelit poistetuksi. Suodatin poistaa jopa hiilimonoksidit CO ja 15 hiilidioksidit C02.With the solution according to the invention, in which the filter unit consists of the above-mentioned combination, all harmful and toxic particles in the tobacco smoke are removed. The filter even removes carbon monoxides CO and carbon dioxide CO2.

Tupakkahuoneen suodattimet on määrävälein vaihdettava, jotta tupakkahuoneen toiminta vastaisi tavoitteita. Tupakkahuone, jonka tilavuuskoko on 8-24 m3, vaatii ilmavirtaustehon, joka 20 on 400-1000 m3/h.The tobacco room filters must be changed periodically so that the operation of the tobacco room meets the objectives. A tobacco room with a volume size of 8-24 m3 requires an air flow capacity of 400-1000 m3 / h.

Keksinnön eräälle sovellutusmuodolle on tunnusomaista se, että suodatinyksikössä suodattimen ja hajusuodattimen välissä on kolmas eurovent-luokiteltu suodatin EU9.An embodiment of the invention is characterized in that the filter unit has a third eurovent-classified filter EU9 between the filter and the odor filter.

25 ' _ Keksinnön eräälle toiselle sovellutusmuodolle on tunnus - : omaista se, että suodattimen EU4-EU5 ja aktiivihiilisuodat- timen välissä on toinen eurovent-luokiteltu suodatin EU9-EU10 ja että hajusuodattimen jälkeen tai sen yhteydessä on 30 aktiivihiilikangas.Another embodiment of the invention is characterized in that there is another Eurovent-classified filter EU9-EU10 between the filter EU4-EU5 and the activated carbon filter and that there is an activated carbon fabric after or in connection with the odor filter.

Keksinnön avulla ja edellä mainitulla yhdistelmällä saadaan tupakoinnin saastuttama ilma jälleen puhtaaksi tupakansavun sisältämistä hiukkasista sekä myrkyllisistä kaasuyhdisteis-35 tä. Eurovent-luokitellut suodattimet EU1-EU4 ovat ns. karkeita suodattimia, jotka erottavat tekstiilikuituja, isompia siitepölyhiukkasia, savua ja tummumista aiheuttavia hiukkasia. Suodattimet EU5-EU9 erottavat ilmasta hienoa pölyä ja siitepölyä, hiili- ja öljysavua sekä bakteereja.By means of the invention and the above-mentioned combination, the air polluted by smoking is again cleansed of the particles contained in tobacco smoke and of toxic gas compounds. Eurovent classified filters EU1-EU4 are so-called coarse filters that separate textile fibers, larger pollen particles, smoke and darkening particles. Filters EU5-EU9 separate fine dust and pollen, carbon and oil fumes and bacteria from the air.

Keksintöä selostetaan seuraavassa esimerkin avulla viittaamalla oheiseen piirustukseen, joka esittää kaaviomaisesti tupakkahuonetta ja sen puhdistusjärjestelmää.The invention will now be described, by way of example, with reference to the accompanying drawing, which schematically shows a tobacco room and its cleaning system.

5 Tupakkahuoneeseen 1 luodaan alipainetta puhaltimen 2 avulla, jolloin korvausilma virtaa sisään oviaukosta nuolen 3 osoittamalla tavalla. Tupakkahuone toimii näin ollen myös koko sen tilan, johon tupakkahuone on sijoitettu, ilmanpuhdisti-mena. Suodatinyksikköön 4 kuuluu karkeasuodatin 5, eurovent-10 luokiteltu luokkaan EU5, joka erottaa ilmasta pölyhiukkasia. Tämän ns. karkeasuodattimen 5 jälkeen on hienosuodatin 6, joka on eurovent-luokiteltu luokkaan EU9. Suodattimen 6 jälkeen on aktiivihiilisuodatin 7. Seuraava suodatinyksikkö on suodatin 8, joka on laajatoiminen hapettaja ja poistaa epä-15 puhtaudet ilmasta adsorption, absorption ja kemiallisen hapetuksen avulla. Suodattimen 8 jälkeen on kolmas eurovent-luokiteltu suodatin 9 EU9. Puhdistusjärjestelmään 4 kuuluu vielä hajusuodatin 10, joka on kemiallisesti modifioitu polypropyleeni -styreeni -kopolymeeri. Tämä hajusuodatin poistaa 20 tupakansavu-ilma-seoksesta hiilimonoksidin CO, jota kaikilla tunnetuilla tupakkahuoneiden suodatinlaitteilla on ollut mahdotonta poistaa.5 Tobacco is created in the room 1 by means of a vacuum blower 2, wherein the replacement air flows in through the doorway of arrow 3 as shown. The smoking room thus also acts as an air purifier for the entire space in which the smoking room is located. The filter unit 4 includes a coarse filter 5, Eurovent-10 classified in class EU5, which separates dust particles from the air. This so-called after the coarse filter 5 there is a fine filter 6, which is eurovent classified in category EU9. After the filter 6 there is an activated carbon filter 7. The next filter unit is a filter 8, which is a wide-ranging oxidizer and removes impurities from the air by adsorption, absorption and chemical oxidation. After filter 8 there is a third eurovent rated filter 9 EU9. The cleaning system 4 further includes an odor filter 10, which is a chemically modified polypropylene-styrene copolymer. This odor filter removes carbon monoxide CO from the 20 tobacco smoke-air mixture, which has been impossible to remove with all known tobacco room filter devices.

Puhaltimen 2 tehoa ohjaa muuntajasäädin 11 ilmamäärän säätä-25 mistä varten kuormituksen mukaan.The power of the fan 2 is controlled by the transformer controller 11 for the air volume control-25 according to the load.

Hajusuodatin voi olla jokin muu samantyyppinen suodatin, kuten edellä on mainittu, tai jotain katalyyttistä jalometallia, joka toimii katalysaattorina.The odor filter may be another filter of the same type, as mentioned above, or some catalytic noble metal which acts as a catalyst.
