a combined filter for electrostatic sena and mechanical cleaning of fine particle золовых flue gas combustion installations

摘要

scope: теплоэнергетика.the filter is located in the general main body 10 along the gas flow очищаемого block электрофильтрации (бэф) 20, a mechanical filtering (bif) 40.as well as a periodic regeneration of filter material. in бэф 20 placed two high-voltage electric field with коронирующими осадительными electrodes 21 and 22.bif 40 includes filter elements (fe) 50 рукавного type, each of which has a cylindrical frame 51 with натянутым on his sleeve 52 of the filter material.bif fe 50 block 40 sets it on the rear wall 11 of the hull 10.a regeneration is a расположенною inside fe 50 on its axis so the tube 70 and removed outside the fe 50 open end for impulse of compressed air in the pipe 70. and the rabbiномерно distributed on the lateral surface of the pipe 70 радиальными outlets соплами 71.the technical results, reducing the межрегенерационного period and prevent the possible destruction of the filtering elements in the process of regeneration.and the efficiency of dust collection by increasing the tightness of the filter elements. 2).
