的高压差问题玻璃钢脱硫塔压差偏高的原因基本上有两个：一是背压，保压的原因有很多，如管道堵塞、脱硫塔塔盘堵塞等；二是上游流量大，锅炉风机风功率过大，但可能能力很小。 How to solve the high pressure difference problem of FRP desulfurization tower There are basically two reasons for the high pressure difference of FRP desulfurization tower: First, there are many reasons for back pressure, such as blockage of pipelines and blockage of desulfurization tower trays; secondly, upstream The flow is large, the wind power of the boiler fan is too large, but the capacity may be small.
There are four distributors in the desulfurization tower: the front baffle of the inlet pipe; the swirl plate mist trap; the three-layer distributor in the tower; the four-layer packing in the tower. The pressure difference formed by the first two settings is the pressure difference outside the tower. The pressure difference formed by SECCO is the pressure difference outside the tower. The two set values for ND are the pressure differences in the tower, and clogging the towers of each distribution unit will result in an increase in pressure differential.
If the pressure difference of the desulfurization tower is found to be too high, the pressure difference meter should be checked and cleaned with a meter. After recovery, the pressure difference changes small and obvious, eliminating the cause of the instrument error.
Secondly, according to data statistics, it was found that the process operating parameters such as solution circulation, operating temperature, pressure, and desulfurization gas volume were unchanged. These two issues must be thoroughly resolved through system shutdown and maintenance to be thoroughly confirmed and processed.
With the development of society and economic progress, industrial cities have gradually risen. This phenomenon has played a significant role in promoting the economic development of cities, but on the basis of people's lives, industrial development has brought new problems. We The environment is deteriorating and air pollution is everywhere. Ion, in the process, smart workers have created some tools to clean the air and reduce pollution, and the FRP desulfurization tower is one of them. The emergence of desulfurization can effectively improve air pollution and desulfurization of industrial waste gas. In addition, the desulfurization tower is easy to maintain. Through equipment configuration, it can play the role of desulfurization and dust removal to varying degrees, and better serve the global environment in which we live.
The working principle of the FRP desulfurization tower: The FRP desulfurization tower uses sodium hydroxide solution as the absorption neutralization liquid to purify the acid mist exhaust gas. The gas is pressed into or sucked into the intake section by a centrifugal fan, and then enters the first filter layer upwards and is discharged. Neutralization reaction. From the first nozzle. The absorbed exhaust gas continues to flow upward to the second filter layer, contacts the neutralizing liquid ejected from the second nozzle, and then reacts again. It is then discharged into the atmosphere through a vortex plate through a hood and an exhaust pipe or a fan.
Product advantages of FRP desulfurization tower:
1. The glass fiber reinforced plastic purification tower is assembled in sections, which has the characteristics of small area and convenient transportation and installation.
2. The product adopts domestic advanced composite materials and high temperature resistant glass fiber reinforced plastic resin, which improves wear resistance and high temperature resistance and greatly prolongs the service life.
three. FRP desulfurization tower is an impact type dust removal and desulfurization device that enters and exits directly. Flue gas directly hits the water surface, saving water, reducing pollution, convenient operation and maintenance, low operating cost, and good dewatering effect. It is an economical and practical wet dust removal method. Desulfurization device.
