Description

Przedmiotem wynalazku jest urzadzenie do katalitycz¬ nego oczyszczania gazów z par i szkodliwych gazów, które wprocesieoczyszczania, w wyniku katalizowanych reakcji utleniania lub redukcji przechodza w substancje nieszko¬ dliwe.Znane sia urzadzenia do katalitycznego oczyszczania gazów stanowiace reaktor zawierajacy warstwe kataliza¬ tora, komore podgrzewania oraz wymiennik ciepla. Wy¬ miennik ciepla i komora podgrzewania sluza do podgrze¬ wania gazów do temperatury reakcji katalitycznej. Wada tychurzadzenjestduzezuzycie materialów, znaczny ciezar i duze zapotrzebowanie powierzchni.Znane sa równiez urzadzenia do katalitycznego oczysz¬ czania gazów, w których reaktor, komora podgrzewania gazów oraz wymiennik ciepla stanowia jedna zwarta kon¬ strukcje. Urzadzenia te zbudowane sa w ten sposób, ze zanieczyszczone gazy przeplywaja promieniowo przez wa¬ rstwe katalizatora usytuowanego w przestrzeni pierscie¬ niowej otaczajacej osiowy kanal, a nastepnie oplywaja rurki wymiennika ciepla rozmieszczone wokól warstwy katalizatora. Komora podgrzewania gazów umieszczona jest nad reaktorem i wymiennikiem ciepla. _ V Urzadzenia te posiadaja nierównomierne obciazenie ka¬ talizatora ze wzgledu na znaczna dlugosc kanalu, wokól którego usytuowany jest katalizator. Ponadto brakw nich wykorzystania powierzchnT wymiany ciepla w Wymienni¬ ku ciepla, ze wzgledu na powstanie martwych przestrzeni w dolnej czesci wymiennika i zmieniajacej sie ilosci gazu wzdluz drogi przeplywu. Ponadto posiadaja utrudniony dostep do katalizatora.Celem wynalazkujest usuniecietychwad i niedogodnos¬ ci. Dla osiagniecia tego celu zostalo wytyczone zadanie, opracowania konstrukcji urzadzenia o duzej skutecznosci dzialania, malych gabarytach, prostego w obsludze i eks¬ ploatacji.Wytyczone zadanie rozwiazane zostalo wedlugwynalaz¬ ku w ten sposób, zew dolnej czesci urzadzeniausytuowany jest wymiennik ciepla zwiazany sztywno z umieszczona nad nim komora podgrzewania, polaczona przestrzenia gazowa z katalizatorem rozmieszczonym w koszach reak¬ tora. Wymiennik ciepla, komora podgrzewania oraz reak¬ tor katalityczny usytuowane sa wzdluzosi obudowy urza¬ dzenia tworzac zwarta jednolita konstrukcje.Przyklad wykonania urzadzenia wedlugwynalazku jest pokazany schematycznie na rysunku.Zanieczyszcony gaz wprowadzony jest do urzadzenia króccem wlotowym 1 do wymiennika ciepla 2, w którym podgrzewa sie cieplem gazów opuszczajacych urzadzenie króccem wylotowym 3. Podgrzewany gaz w wymienniku ciepla 2 wchodzi do komory podgrzewania 4 opalanej za pomoca palnika 5 i podgrzewa sie do temperatury reakcji katalitycznej. Z komory podgrzewania gazu 4,gaz wplywa do reaktora katalitycznego, skladajacego sie z komory I zrozmieszczonymi symetrycznie w niej koszami 7z katali¬ zatorem 8. Wprowadzony gaz do wnetrza koszy 7 z katali¬ zatorem 8 przechodzi przez katalizator 8 i^wychodzi na zewnatrz koszy 7. Nastepnieoczyszczony gaz kierowany jest przewodami 9 do wymiennika ciepla 2 i uchodzi króccem wylotowym 3. 86394 '86 394 Ljlot gazu oczyszczonego n/ot ousu zanieczyszczonego Sklad wykonano w DSP, zam. 3885 Druk w UP PRL, naklad 125+20 egz.Cena zl 10 - PLThe subject of the invention is a device for the catalytic purification of gases from vapors and harmful gases, which in the process of purification, as a result of catalyzed oxidation or reduction reactions, turn into harmful substances. and a heat exchanger. The heat exchanger and the heating chamber are used to heat the gases to the catalytic reaction temperature. The disadvantage of these devices is the high consumption of materials, considerable weight and high floor space requirements. There are also known devices for catalytic gas cleaning in which the reactor, gas heating chamber and heat exchanger constitute one compact structure. These devices are constructed in such a way that the contaminated gases flow radially through the catalyst layer situated in the annular space surrounding the axial channel, and then flow around the heat exchanger tubes arranged around the catalyst layer. The gas heating chamber is located above the reactor and the heat exchanger. These devices have an uneven catalyst load due to the considerable length of the channel around which the catalyst is located. Moreover, they lack the use of the heat exchange surfaces in the heat exchanger, due to the formation of dead spaces in the lower part of the exchanger and the changing amount of gas along the flow path. Moreover, they have a difficult access to the catalyst. The aim of the invention is to remove these defects and inconveniences. In order to achieve this goal, a task was set out to develop a device structure with high efficiency, small dimensions, easy to use and operate. there is a preheating chamber, gas spaces connected to the catalyst arranged in the reactor baskets. The heat exchanger, the heating chamber and the catalytic reactor are located along the length of the device housing, forming a compact, uniform structure. An example of the device according to the invention is shown schematically in the drawing. Contaminated gas is introduced into the device through the inlet port 1 to the heat exchanger 2, in which it is heated with the heat of the gases leaving the device through the outlet pipe 3. The heated gas in the heat exchanger 2 enters the heating chamber 4 fired by the burner 5 and is heated to the temperature of the catalytic reaction. From the gas heating chamber 4, the gas enters the catalytic reactor, consisting of the chamber I, symmetrically arranged in it baskets 7 with a catalyst 8. The gas introduced into the interior of the baskets 7 with the catalyst 8 passes through the catalyst 8 and exits the outside baskets 7 Then the purified gas is directed through pipes 9 to the heat exchanger 2 and it is discharged through the outlet connection 3. 86394 '86 394 Lj inlet of purified gas, ie contaminated gas. 3885 Print in the Polish People's Republic, circulation 125 + 20 copies Price PLN 10 - PL
