Title: Method and apparatus for desulfurizing exhaust gas
Inventor: NAKAGAWA KENICHI
IPC: B01D53/34
Filed: 1987-03-07
Abstract: PURPOSE:To efficiently remove sulfur oxides in exhaust gas without necessitating pH-controller at low cost, by bringing the exhaust gas contg. sulfur oxide into contact with a pellet-shaped magnesium hydroxide as a desulfurizing agent. CONSTITUTION:When the exhaust gas contg. sulfur oxide such as gaseous sulfur dioxide, which is exhausted from a furnace 8 generating the exhaust gas such as a heavy oil burning fuel furnace or a boiler, is introduced into an absorbing body 1, the sulfur oxide in the exhaust gas is absorbed by the desulfurizing liq. Then, said liq. flows out to a circulating tank 2 below the bottom of tower and then is flowed into the top of the tower again through a pipe 4 by a pump 3. At that time, a part of the desulfurizing liq. is introduced into a reaction tower 7 and is reacted with the above-mentioned magnesium hydroxide there and then is returned again to the circulating tank 2. In the above-mentioned process, the efficient desulfurization is performed without necessitating pH- controller by using the pellet-shaped magnesium hydroxide as the desulfurizing agent.

     CONSTITUTION: A plurality of fins 2 having engaging portions is inserted into the outer surface of a cooling pipe 1. A core metal 4 has a diameter smaller than the I.D. of the cooling pipe 1 and receiving portion 3 at its end. Metal collars 8 and expandable 0-ring 6 are arranged in the space between the receiving portion 3, the core metal 4, and a slidable pressing body 5. The so assembled expanding device 7 is inserted into the cooling pipe 1, and the core metal 4 is fixed, the press body 5 is pushed to displace the 0-ring in radial direction so that the cooling pipe 1 is firmly contacted with the fins. The process causes the external surface of the cooling pipe to be plastically deformed to engage with the fins 2 internal surfaces. As a result, fluid flow changes to cause more effective heat transmission. The process, thus, provides simple, inexpensive means to produce heat exchangers.
