Technical Problem

[0004]喷淋浆液对烟气的吸收反应速率取决于烟气与浆液的相对速度、有效传质面积、接触时间等多种因素,为使烟气与喷淋浆液充分接触,工程上一般采用多层喷淋的模式,每层喷淋均匀布置大量喷嘴的方式,但为了避免喷淋浆液沿吸收塔内壁向下流动而起不到雾化吸收效果,以及很多工程中为了防止近内壁喷嘴长时间直接冲刷吸收塔内壁导致的磨穿现象,雾化喷嘴在吸收塔内的布置位置一般与内壁具有一定的间距,这就导致了贴近吸收塔内壁区域的喷淋浆液覆盖量比中心区域少,这样吸收塔截面上就形成了一个靠内壁的烟气低效吸收盲区,在这个烟气低效吸收盲区内,烟气得不到喷淋浆液的充分吸收和洗涤而直接排出吸收塔外,大大降低了脱硫效率

Benefits of technology

[0016] This invention slows down the flow rate of exhaust gas in the fiberglass spray tower by using baffles and guide plates, thereby increasing the contact time between the exhaust gas and the slurry. The exhaust gas enters the upper side of the fiberglass spray tower through the exhaust gas inlet of the guide plate and is confined, avoiding the occurrence of blind zones in flue gas absorption. This solves the problem of significantly reduced desulfurization efficiency in existing devices due to the inefficient absorption of flue gas in blind zones.

Description

Technical Field

[0001] This utility model relates to the field of flue gas diversion technology for fiberglass spray towers, and specifically to a flue gas diversion device for fiberglass spray towers. Background Technology

[0002] A fiberglass spray tower is a waste gas treatment device made primarily of fiberglass (FRP). It efficiently removes pollutants (such as acidic gases, dust, and organic waste gases) from industrial waste gases through the principle of spray absorption.

[0003] A spray tower, as a simple tower-type gas-liquid mass transfer device, contains liquid sprayers that disperse the liquid into fine droplets that fall downwards. The gas then contacts these droplets in a counter-current flow to transfer mass. The advantages of this equipment are its simple structure, low cost, and low gas pressure drop. The disadvantages are high power consumption for liquid spraying, significant entrainment of mist in the outlet gas, and severe backmixing within the equipment. It is often used for the absorption of easily soluble gases and can also be used for gas scrubbing. However, when acidic gases such as sulfur dioxide are absorbed by spray towers, the resulting acidic solution can corrode the tower. Therefore, for the absorption of some acidic gases, spray towers made of fiberglass are often used.

[0004] The absorption reaction rate of flue gas by spray slurry depends on various factors such as the relative velocity between flue gas and slurry, effective mass transfer area, and contact time. To ensure sufficient contact between flue gas and spray slurry, a multi-layer spraying mode is generally adopted in engineering, with a large number of nozzles evenly arranged in each layer. However, to avoid the spray slurry flowing downward along the inner wall of the absorption tower and failing to achieve atomization absorption effect, and to prevent the nozzles near the inner wall from directly scouring the inner wall of the absorption tower for a long time and causing wear, the atomizing nozzles are generally arranged at a certain distance from the inner wall in the absorption tower. This results in less spray slurry coverage in the area close to the inner wall of the absorption tower than in the central area. As a result, a blind zone of inefficient flue gas absorption is formed on the cross-section of the absorption tower near the inner wall. In this blind zone, the flue gas is not fully absorbed and washed by the spray slurry and is directly discharged outside the absorption tower, which greatly reduces the desulfurization efficiency.
