DEVICE FOR PURIFICATION OF THE DUSTY HOT GASSES AND FOR UTILIZATION OF HEAT Russian patent published in 2005 - IPC

FIELD: construction materials industry; metallurgical industry; chemical industry and other industries.

SUBSTANCE: the invention is pertaining to a wet purification of dusty hot gases by a liquid acting in the capacity of the water-flushing agent, and also to the further use of the heated liquid. The invention may be realized in construction materials industry, chemical, metallurgical and other industries. The device consists of a body, the lower part of which forms a liquid collector, the located accordingly in the lower and the upper parts of the body connecting pipes for feeding and removal of a gas, a drop catcher rigidly fixed under a connecting pipe of the gas discharge, stages of the gas purification rigidly fixed in the body under the drop catcher. A stage of the gas purification includes a built-in nozzle consisting of the elongated elements fixed in the body and oriented by the big axis along the stream of a heat-carrying agent, a distributive lattice rigidly fixed on the body under the nozzle, a liquid feeding device rigidly fixed under the distributive lattice in the way, that apertures for the liquid feeding are oriented by a gas stream, an additional lattice mounted under the device of the liquid feeding and rigidly fixed on the body. The design has at least two stages of a gas purification made similarly. At that the body in the place of the two stages connection has external bins for the collection of the heated liquid, and has windows for passages of the liquid. The windows are located opposite to the bins. The gas purification stages are located vertically and connected among themselves by the connecting pipes linking the bins of the above located gas purification stage with the device of a liquid feeding to the beneath located gas purification stage. The invention allows to raise efficiency of purification of the effluent gases with simultaneous decrease of their outlet temperature and with the further use of the liquid heated during purification.

EFFECT: the invention ensures increased efficiency of the effluent gases purification with a simultaneous decrease of their outlet temperature and advantage of the further use of the liquid heated during purification.
