A complete set of wet scrubbers requires accurate calculations. The wet scrubber calculates parameters such as diameter, height, wall thickness, air volume, etc. The calculation method of wet scrubbers affects the efficiency and functions of exhaust gas treatment, such as: exhaust gas stays in the wet scrubber Time needs wet scrubber calculation. To learn the calculation method of wet scrubber, you must first understand the principle of wet scrubber and what parts of the wet scrubber are composed. In fact, the appearance of wet scrubber looks very simple and includes accessories. It is not complicated, but it is difficult to complete the design of a wet scrubber, because there are a lot of calculations for a wet scrubber. If it is only made according to the picture, it is of course simple, and you don’t need to read it down. , Because there is no shortage of processing factories in our country, I think any drawing of a plastic sink with a wet scrubber can be processed. But it is a bit difficult to figure out the size of each part and why it is so different. Wet scrubber production diagram In this section, we will not mainly talk about the calculation method of wet scrubber. First, let’s get started. We will do some necessary information on the size, diameter, height, material thickness of the wet scrubber, how to choose the pump, and the external construction of the wet scrubber. Explain that it is easy to understand the role of these parts, and then talk about the calculation method of the wet scrubber. This section is mainly for the introduction, for users who want to purchase wet scrubbers as an introductory reference study, colleagues can not read it.
Dimensions of wet scrubber
The design size of the PP wet scrubber is one of the factors that determine its performance. Therefore, it is necessary to fully calculate or refer to the exhaust gas treatment air volume, exhaust gas type and concentration of the completed project to accurately determine it.
Diameter of wet scrubber
The design diameter of the wet scrubber is mainly to consider the speed and residence time of the exhaust gas in the tower, because this residence time directly affects the contact time of the exhaust gas in the packing layer with the spray agent, such as the acid-base neutralization reaction, and the air volume is constant. In the case of, the larger the diameter of the tower, the lower the wind speed and the longer the relative residence time. The more complete the chemical reaction, the better the exhaust gas treatment effect. Different specifications and dimensions of wet scrubbers
Design height of wet scrubber
The height of the wet scrubber also determines how long the exhaust gas stays in the pp wet scrubber. The key to the calculation of the height of the wet scrubber is the height of the filler layer and the height of the defogging layer. These two values directly affect the effect of the wet scrubber in treating exhaust gas, because the filler layer is the contact medium, and the exhaust gas occurs in the filler layer and the spray liquid. An important place for the conversion of gas phase and liquid phase, and the role of the defogging layer is to remove the water mist of the purified air to ensure that the air exhausted by the rear chimney is dry. If the design height of the PP wet scrubber is too low, the thickness of the spray layer and the filler layer will be very thin, and the exhaust gas will not be fully absorbed and be discharged into the atmosphere. The specific height of the wet scrubber is The height of the water tank, the height of the exhaust gas inlet, the height of the grille layer, the height of the wet scrubber packing layer, the height of the spray layer, the height of the defogging layer and the water height reserved from the spray layer to the filler layer, and a tower top The height of the outlet head. Usually the height of the packing layer is 1200mm, the height of the defogging layer is 600mm, and the total height of the general tower single-layer wet scrubber is about 4500mm.
