接触塔に関するものである。[Detailed description of the invention] This invention is a process in which dust-containing gas such as combustion exhaust gas discharged from a boiler etc. is passed through to remove dust and collect impurities, heated by a gas heater, and released from a chimney. This relates to a gas-liquid contact tower used for dust removal, etc.

た。 However, with this configuration, if the gas velocity in the mist eliminator exceeds a certain value, the mist collected by the mist eliminator may be re-splattered and exit the tower, so the gas flow velocity must be slowed down. This was to prevent the mist from scattering again.

洗浄用のノズル装置である。 In a vertical column 3, a gas inlet 1 is opened on one side of the lower part, and a gas outlet 2 is also opened on one side of the top so that gas is released in a horizontal direction. A large number of spray nozzles 4
A gas-liquid contact layer 5 is disposed with the gas inlet facing downward, and the gas flowing in from the gas inlet 1 and rising comes into contact with minute droplets sprayed from the spray nozzle 4 and absorbs impurities in the gas with the spray droplets. furthermore, a mist eliminator 6 is arranged above the arrangement position of the spray nozzle 4, and the mist eliminator 6 is formed by horizontally arranging a plurality of zigzag plates 7 formed in a zigzag shape. A plurality of guide plates 8 are arranged on the upper part of the mist eliminator 6 so as to be inclined so that the gas flows in a direction opposite to the direction of the gas outlet 2, and a plurality of guide plates 8 are arranged on the upper part of the mist eliminator 6 so as to be inclined so that the gas flows in a direction opposite to the direction of the gas outlet 2. , a slope 9 directly facing the gas flowing while being regulated by the guide plate 8;
is provided so that the gas passing through the mist eliminator 6 and the re-dispersed mist 10 collide with the slope 9 along the guide. 11 is a nozzle device for cleaning the mist eliminator 6.

捕集することができる。 With the above configuration, when gas enters the tower from the gas inlet 1, the gas comes into contact with minute droplets sprayed from the spray nozzle 4 while rising. The droplets generated in the tower are extremely small, with an average of 1000 to 2000 microns, and the smallest one is several tens of microns, in order to increase the contact area with the gas. This mist is scattered by the upward flow of gas, but is collected by the mist eliminator 6;
If the flow rate of gas passing through is high, it will be entrained by the gas and re-entrained. That is, when the gas velocity in the mist eliminator 6 exceeds a certain value (re-entrainment speed), the mist starts to re-entrain from the end of the zigzag plate 7. This re-splattered mist 10 is generated in the gas-liquid contact layer 5 and becomes larger due to polymerization.
Its particle size is several mm. Such scattered mist does not need to go out of the tower even if the gas flow rate is higher than the re-entrainment speed of the mist.In this regard, in the present invention, the guide plate 8 is arranged in a direction opposite to the gas outlet 2. In addition, since the mist that is rectified by the guide plate 8 and is scattered along with the gas collides with the slope 9, the re-dispersed mist is collected without flowing out from the gas outlet 2. be able to.
