The invention relates to a gas lift dissolving drum used for dissolving solids with low dissolving rate and with mechanical impurities. The gas lift dissolving drum comprises a cylinder-shaped jacket (1) provided at its ends with two tube plates (2) having holes wherein several columns of long pipes (3) and columns of short pipes (4) are mounted, said pipe columns together with some radial walls (7 and 8) firmly fixed in caps (5 and 6) forming alternating ascending and descending flowing zones where the air (gas)-liquid-solid mixture and, respectively, the liquid-solid mixture flow exchanging heat with the heating agent flowing through the tube interspace. |
