UV光氧催化设备排风系统很重要

浏览量:?? 来源:??作者:唯一

随着现代化工行业排放出来的有机废气逐渐增多,UV光氧催化设备以其良好的净化效果也变得越来越热门,其中设备良好的催化效果需要其内部保证良好的通风和排风来保证,这就看出排风系统的重要性。

With the gradual increase of organic exhaust gas discharged from modern chemical industry, UV photocatalysis equipment has become more and more popular because of its good purification effect. The good catalytic effect of equipment requires good ventilation and exhaust air to ensure, which shows the importance of exhaust air system.

光氧催化局部排风系统的吸风支管一端是机上吸口,另一端在汇流三通处与干管相接,支管气流与干管气流在汇流三通处具有公共点称为两股气流的汇合点,两股气流在汇合点汇合,一般动压是不等的,但其静压相等。干管气流到达汇合点的静压称为剩余静压,它是汇合点的实际静压。吸口与汇合点的静压差是支管吸风的动力。对于形状和尺寸给定的支管,只要吸口状态和汇流三通汇合点处的静压一定,支管的吸风量就一定。支管吸口的状态以及支管的形状和尺寸确定之后,根据风量或风速,就可求得支管在汇流三通处的静压,称为该支管的计算静压。

One end of the suction branch of the photocatalytic partial exhaust system is the upper suction port, and the other end is connected with the main pipe at the confluence tee. The common point between the branch pipe air flow and the main pipe air flow at the confluence tee is called the confluence point of two airflows. The two airflows converge at the confluence point. The general dynamic pressure is unequal, but their static pressure is equal. The static pressure at the junction point is called residual static pressure, which is the actual static pressure at the junction point. The static pressure difference between the suction port and the convergence point is the power of the branch suction. As long as the static pressure at the junction point of the suction port and the confluence tee is constant, the suction capacity of the branch pipe with given shape and size will be constant. After the state of the branch suction and the shape and size of the branch are determined, the static pressure of the branch at the three junctions of the confluence can be obtained according to the air volume or wind speed, which is called the calculated static pressure of the branch.

UV光氧催化设备各支管的形状和尺寸以及吸口状态都相同,如果给定的吸风量也相等,各支管的计算静压就相等。如果干管气流到达汇合点的剩余静压也相等,那么各支管的吸风量就相等,这就是所谓的静压恒定原理。如果干管气流到达汇合点的剩余静压不仅相等,而且等于各支管的计算静压,那么各支管的吸风量不仅相等,而且能按照给定的风量吸风,这就是均匀吸风原理。

The shape, size and suction state of each branch of UV photocatalytic equipment are the same. If the given suction volume is equal, the calculated static pressure of each branch is equal. If the residual static pressure of the main pipe reaches the junction point equally, then the air suction capacity of each branch pipe is equal, which is the so-called static pressure constant principle. If the residual static pressure at the junction point is not only equal, but also equal to the calculated static pressure of each branch, then the air suction capacity of each branch is not only equal, but also can suck according to the given air volume. This is the principle of uniform air suction.

就一般情况而言,对于任意形状和尺寸的支管以及任意给定的风量,只要求出各支管的计算静压,并使干管气流到达汇合点的剩余静压等于该支管的计算静压,则该支管就能按给定的风量吸风,这就是定量吸风原理。它对吸风管道的设计更具有普遍意义。

Generally speaking, as long as the calculated static pressure of each branch and the residual static pressure of the main pipe reaching the confluence point is equal to the calculated static pressure of the branch, the branch can suck air according to the given air volume, which is the principle of quantitative suction. It has more universal significance for the design of suction duct.

UV光氧催化设备的排风系统专门针对其工作方式进行独特设计,从而保证吸风量和排风效果都能处在正常范围内,这样才能够促进设备保持良好循环,从而提高净化效率。

The exhaust system of UV photocatalytic equipment is specially designed for its working mode, so as to ensure that the air intake and exhaust effect are within the normal range, so as to promote the equipment to maintain a good cycle, thereby improving the purification efficiency.
