摘要： In an absorbing tower including an absorption unit of relatively small diameter capable of absorption and removal by an absorbent slurry for exhaust gas purification and a tank unit of relatively large diameter for temporarily storing the absorbent slurry flowing down from the absorption unit, the tank unit and the absorption unit are joined together by a conical member. By disposing an entrance flue at the conical member, a distance from an upper portion of the conical member to a spray header is shortened, and a height of the absorbing tower can be reduced accordingly. By extending a front end of the entrance flue to the absorption unit into which droplets of the absorbent slurry fall, a high-temperature exhaust gas from a boiler, etc., that has passed through the entrance flue, is made to pass through a circumference of the conical member so that an inexpensive material can be used in the conical member.

摘要： An absorbing tower is provided in its side wall with a gas entrance for introducing a combustion exhaust gas into the absorbing tower, and an absorbing liquid is sprayed from the nozzles of a spray header into the exhaust gas introduced to rise from the gas entrance. A trough is arranged in the side wall of the absorbing tower and above the gas entrance, and a nose having a horseshoe shape in a top plan view and extending into tower is disposed in the tower side wall portion of the gas entrance other than the portion arranging the trough and at the same or at substantially the same height as the portion of the trough. The absorbing liquid, which is sprayed from the nozzle and drops along the absorbing tower wall portion, is rescattered to the center portion of the absorbing tower excepting the entrance of the absorbing tower, so that the gas-liquid contact efficiency is improved while suppressing an increase in pressure loss, thereby to prevent the drift of the gas at the tower wall portion.

摘要： An absorbing tower provided with plural spray headers (3) which each have a plurality of spray nozzles (5) and are arranged in a multi-stage state in the flow direction of exhaust gas, in which an absorption liquid containing a slurry of limestone or lime is sprayed through the nozzles (5) to absorb and remove sulfur oxide contained in exhaust gas, wherein each spray nozzle (5) is of an annular spray type (a hollow cone type) and the spray nozzles (5) in the neighborhood of the tower wall have such a structure that the fluid is sprayed radially at spray angles of 50 to 80° with the direction counter to the flow of exhaust gas as the center, while the nozzles (5) in the central part of the tower have such a structure that the fluid is sprayed radially at spray angles of 80 to 130° with the direction counter to the flow thereof as the center. According to the invention, the channeling of exhaust gas in the tower can be inhibited by using two kinds of spray nozzles (5) to thereby prevent the desulfurization performance from lowering caused by blow-by of exhaust gas in the neighborhood of the tower wall. Further, an extremely high pressure loss can be inhibited by the flow-regulating effect of sprayed droplets. Thus, a wet-type exhaust gas desulfurizer with a reduced total cost is obtained.
