Description

Gaz uzywany do czyszczenia powierzch¬ ni odpylajacych w oczyszczarkach suchych musial byc ogrzewany do wlasciwej tem¬ peratury w stosownych ogrzewaczach po¬ wierzchniowych, w celu zapobiezenia po¬ wstawaniu na powierzchniach suszarki ro¬ sy. Podobny przegrzewacz znacznie pod¬ nosi koszt urzadzen do oczyszczania ga¬ zów, wymaga osobnego dozoru i zuzywa stale pewna ilosc ciepla w postaci pary lub gazu. Przy zbyt Wysokiem przegrzaniu ga¬ zu zachodzi obawa uszkodzenia powierzch¬ ni odpylajacych, np, tkaniny w filtrach ga¬ zowych urzadzenia.Trudnosci powyzsze mozna usunac na¬ grzewaniem gazu powrotnego w samych fil¬ trach* W ten sposób otrzymuje sie odraza wlasciwa temperature, przy której po¬ wierzchnie odpylajace nie ulegaja niebez¬ pieczenstwu zanieczyszczenia lub przepa¬ lenia. Jednoczesnie osiaga sie znaczne u- proszczenie budowy calego urzadzenia.Wybór miejsca do wprowadzenia ga¬ zu powrotnego do oczyszczarki stanowi za¬ danie konstruktora. Tutaj chodzi tylko o wytworzenie dostatecznej powierzchni o- grzewalnej. Rysunek zawiera przeto je¬ dynie przyklady rozwiazania takiego zada¬ nia, poniewaz ostateczny uklad czesci za¬ lezy od systemu oczyszczarki.Fig. 1 przedstawia przewód 1 do gazu powrotnego pod powala komory filtrowej2. Zawoty przelacznikowe 3 wlaczone sa do przewodu, co usuwa potrzebe budowy osobnych komór zaworowych.Fig. 2 wyobraza podobny do powyzsze¬ go uklad, w którym równiez i przewód ssa¬ cy 4 miesci sie pod powala. Wedlug fig. 3 przewód zwrotny miesci sie pomiedzy dwiema komorami odpylajacemi 2 i 2\ Na fig. 4 przewód 1 lezy ponad kanalami 3 gazu surowego calkowicie w przestrzeni gazowej.Korzystnem równiez bywa (fig. 5) umie¬ szczenie przewodu 1 pomiedzy przegrze- waczem 2 surowego gazu i komora oczy¬ szczajaca 3, albo tez zastosowanie czesci przegrzewacza do ogrzewania gazu po¬ wrotnego, Niema przytem obawy nadmier¬ nego przegrzania gazu, poniewaz prze¬ strzen przegrzewacza stale wymienia cie¬ plo z komora oczyszczajaca. PLThe gas used to clean the dedusting surfaces in dry cleaners had to be heated to the appropriate temperature in the appropriate surface heaters to prevent dew from forming on the dryer surfaces. A similar superheater considerably increases the cost of gas cleaning equipment, requires separate supervision, and consumes a constant amount of heat in the form of steam or gas. If the overheating of the gas is too high, there is a risk of damaging the dedusting surfaces, e.g. the fabrics in the gas filters of the device. The above difficulties can be eliminated by heating the return gas in the filters themselves * In this way, the correct temperature is disgusted with whose dedusting surfaces are not subject to the danger of contamination or burns. At the same time, a considerable simplification of the construction of the entire plant is achieved. The choice of the place to introduce the return gas to the blasting machine is the task of the designer. Here it is only a matter of creating a sufficient heating surface. The drawing therefore contains only examples of a solution to such a task, since the final layout of the parts depends on the blasting machine system. 1 shows a conduit 1 for return gas under knocks down filter chamber 2. Diverter valves 3 are connected to the pipe, which eliminates the need to build separate valve chambers. 2 depicts a system similar to the above, in which the suction tube 4 also fits under the collapse. According to Fig. 3, the return line is located between the two dedusting chambers 2 and 2. In Fig. 4, the line 1 lies above the raw gas channels 3 completely in the gas space. It is also advantageous (Fig. 5) to place the line 1 between the superheater 2 of the raw gas and the purge chamber 3, or the use of a superheater portion to heat the back gas, there is therefore no fear of overheating the gas because the superheater space continuously exchanges heat with the purge chamber.

Claims

Patent claims. 1. Device for dry cleaning of gases with a device for cleaning dust removal surfaces by means of heated return gas, characterized by the fact that the return gas is heated in pipes or ducts connected to the cleaner or placed inside it, so that a separate heater gas becomes redundant.

2. Device according to claim 1, the significant point is that the recycle gas conduit lies beneath the treatment chamber.

3. Device according to claim 1 and 2, characterized by the fact that diverter valves are housed in the return line.

4. Device according to claim 1, in that the recycle gas conduit lies between a double series of purification chambers.

5. Device according to claim 1, characterized in that the recycle gas conduit is above the raw gas conduit.

6. Device according to claim 1, that is, the recycle gas conduit lies between the purge chamber and the raw gas superheaters.

7. Device according to claim 1, that is, the recycle gas is heated in a separate section of the raw gas superheater. Halbergerhutte Gesell schaft mit beschrankter Haftung. Deputy: M.
