Description

PL 72 127 Y1 2 Opis wzoru Przedmiotem wzoru uzytkowego nagrzewnica powietrza, majaca zastosowanie do ogrzewania powietrza nagrzewanego spalinami z palnika pelletowego. Przedmiotem rozwiazania przedstawionego w opisie US 2006236906 jest automatyczne urza- dzenie grzewcze do spalania paliwa biomasy i sposób zawierajace komore spalania majaca pochylona podloge i podajnik slimakowy dostarczajacy paliwo z biomasy do spalania. Komora spalania z otworem slimaka podajacego w scianie komory spalania. Slimak do usuwania popiolu z podstawy wspomnianej nachylonej podlogi oraz wymiennik ciepla przenosi powietrze doprowadzane przez komore spalania w celu ogrzania przestrzeni takiej jak budynek legowy. Wentylator napedza powietrze nawiewane przez wymiennik ciepla, a sterowanie reguluje predkosc wentylatora i prace podajnika slimakowego. Uklad sterowania utrzymuje stala, zadana temperature powietrza nawiewanego do kurnika, zmieniajac nate- zenie przeplywu powietrza w zaleznosci od temperatury powietrza wlotowego i temperatury w komorze spalania. Istota wzoru uzytkowego, którym jest nagrzewnica powietrza, polega na tym, ze wylot spalin pal- nika, osadzonego na uchylnej scianie, usytuowany jest w wielosciennej komorze dopalania 2, zwezaja- cej sie ku dolowi. W strefie przeciwnej wylotu spalin, komora dopalania ma pierwsza komore nawrotna, polaczona z górnymi kanalami nawrotu spalin, o osiach w zasadzie równoleglych do osi komory dopa- lania. Wylot kanalów usytuowany jest w drugiej komorze nawrotnej, której jedna ze sciana jest uchylna sciana. W drugiej komorze nawrotnej, usytuowane sa wloty dolnych kanalów, o osiach w zasadzie rów- noleglych do osi komory dopalania, których wyloty usytuowane sa w czopuchu polaczonym dalej z ko- minem. Komora dopalania w swej dolnej strefie ma slimakowy transporter popiolów. Ponizej dolnych kanalów usytuowany jest wentylator, tloczacy powietrze przez przestrzenie miedzy kanalami przeplywu spalin do kanalu odbioru nagrzanego powietrza. Dzieki rozwiazaniu wedlug wzoru uzyskano nastepujace efekty techniczno-uzytkowe: ? uzyskanie wysokiej sprawnosci wymiany ciepla, ? mozliwosc automatycznego usuwania popiolów i zuzli ze strefy wymiennika ciepla, podczas pracy wymiennika, ? wysoki wspólczynnik separacji czastek stalych ze strumienia spalin poprzez trzykrotny przelom kierunku tego strumienia, ? mozliwosc rewizyjnego otwarcia sciany z palnikiem, co ulatwia dostep do wszystkich kanalów spalinowych, ? zwarta konstrukcja. Przedmiot wzoru uwidoczniono na rysunku, na którym na fig. 1 pokazano w schematach przekrój nagrzewnicy w wymienniku ciepla w plaszczyznie pionowej, przechodzacej przez os transportera, na- tomiast na fig. 2 pokazano nagrzewnica w wymienniku w przekroju w plaszczyznie pionowej prostopa- dlej do kierunku przeplywy spalin, przechodzacej przez os wentylatora. Nagrzewnica powietrza, zasilana palnikiem peletowym, ma komore dopalania 2. Wylot spalin pal- nika 1, osadzonego na uchylnej scianie 12, usytuowany jest w wielosciennej komorze dopalania 2, zwe- zajacej sie ku dolowi. W strefie przeciwnej wylotu spalin, komora dopalania 2 ma pierwsza komore nawrotna, polaczona z górnymi kanalami 4 nawrotu spalin, o osiach w zasadzie równoleglych do osi komory dopalania 2. Wylot tych kanalów 4 usytuowany jest w drugiej komorze nawrotnej 8, której jedna ze sciana jest uchylna sciana 12. W drugiej komorze nawrotnej 8, usytuowane sa wloty dolnych kanalów , o osiach w zasadzie równoleglych do osi komory dopalania 2. Wyloty tych kanalów 5 usytuowane sa w czopuchu polaczonym dalej z kominem 10. Dodatkowo komora dopalania 2 w swej dolnej strefie ma slimakowy transporter 3 popiolów, natomiast ponizej dolnych kanalów 5 usytuowany jest wentylator 6 tloczacy powietrze przez przestrzenie miedzy kanalami przeplywu 4 spalin do kanalu 7 odbioru na- grzanego powietrza Spaliny z palnika 1 – wplywaja do wnetrza komory dopalania 2. Spaliny na tylnej scianie komory dopalania 2 kierowane sa do kolejnego ciagu dopalania przez kanaly 4 i przeplywaja do drugiej komory nawrotnej 8, której jedna ze scian stanowi sciana uchylna 12, dalej przez dolne kanaly 5 przedostaja sie kominem 10 poza nagrzewnice. W strefie kanalów wentylator 6 wtlacza powietrze, które omywajac kanaly 4 i 5 nagrzewa sie i przeplywa do kanalu wyjsciowego 7. PL PL PL PL EN 72 127 Y1 2 Description of the model The subject of the utility model is the air heater, which is used to heat the air heated by flue gas from a pellet burner. The subject of the solution disclosed in US 2006236906 is an automatic heating device for burning biomass fuel and a method comprising a combustion chamber having an inclined floor and a screw feeder for supplying biomass fuel for combustion. Combustion chamber with a feeding screw hole in the wall of the combustion chamber. A slug for removing ash from the base of said sloped floor and a heat exchanger transports air supplied through the combustion chamber to heat a space such as a leg house. The fan drives the air supplied through the heat exchanger, and the control regulates the fan speed and the work of the screw feeder. The control system maintains a constant, set temperature of the air supplied to the house, changing the air flow rate depending on the temperature of the inlet air and the temperature in the combustion chamber. The essence of the utility model, which is an air heater, consists in the fact that the exhaust gas outlet of the burner, mounted on a hinged wall, is located in a multi-walled afterburning chamber 2, tapering downwards. In the zone opposite to the exhaust gas outlet, the afterburning chamber has a first reversing chamber connected to the upper exhaust gas return ducts with axes substantially parallel to the axis of the afterburning chamber. The outlet of the channels is located in the second reversing chamber, one of the walls of which is a tilting wall. In the second reversing chamber, there are inlets of the lower channels, with axes essentially parallel to the axis of the afterburning chamber, the outlets of which are located in the flue connected further with the pipe. The afterburner chamber has an ash conveyor in its lower zone. Below the lower channels there is a fan, which forces air through the spaces between the exhaust gas flow channels to the hot air receiving channel. Thanks to the solution according to the formula, the following technical and operational effects were obtained:? obtaining high heat exchange efficiency,? possibility of automatic removal of ashes and waste from the heat exchanger zone during the heat exchanger operation,? high separation coefficient of solid particles from the flue gas stream through a threefold break in the direction of this stream,? the possibility of the revision opening of the wall with the burner, which facilitates access to all flue gas ducts,? compact structure. The subject of the pattern is shown in the drawing, in which Fig. 1 shows the diagrams of the cross-section of the heater in the heat exchanger in a vertical plane passing through the axis of the conveyor, while Fig. 2 shows the heater in the exchanger in a cross-section in a vertical plane perpendicular to the direction of exhaust gas flow passing through the fan axis. The air heater, powered by a pellet burner, has an afterburning chamber 2. The burner fume outlet 1, mounted on a hinged wall 12, is located in a multi-walled after-burning chamber 2, taper downwards. In the zone opposite to the exhaust gas outlet, the after-combustion chamber 2 has a first reversing chamber connected to the upper exhaust gas reversing channels 4, with axes essentially parallel to the axis of the after-combustion chamber 2. The outlet of these channels 4 is located in the second reversing chamber 8, one wall of which is tilting wall 12. In the second reversing chamber 8, there are inlets of the lower channels, with axes essentially parallel to the axis of the afterburning chamber 2. The outlets of these channels 5 are located in a flue connected further with the chimney 10. Additionally, the afterburning chamber 2 in its lower zone has a screw conveyor 3 of ashes, while below the lower channels 5 there is a fan 6 forcing air through the spaces between the flue gas flow channels 4 to the channel 7 for receiving hot air. Exhaust gas from the burner 1 - flows into the interior of the afterburner chamber 2. Exhaust gas on the rear wall of the afterburner chamber 2 are directed to the next afterburning sequence through channels 4 and flow to the second reversing chamber 8, which they eat The bottom of the walls is a tilting wall 12, then through the lower channels 5 they pass through the chimney 10 beyond the heaters. In the area of the ducts, the fan 6 draws in air which, by washing through ducts 4 and 5, heats up and flows to the output duct 7. EN EN EN EN
