How to choose the air volume of UV light purifier

Many users are not sure how to determine the air volume when they want to purchase UV photodegradation equipment. Now Dongguan Zike environmental protection equipment manufacturer analyzes the air volume selection of UV photodegradator.

First of all, the selection of UV light purifier will involve the air volume of the equipment. The air volume refers to the number of cubic meters of waste gas processed by the light purifier per hour. The treatment conditions of each waste gas are different, the plant area is different, and the treatment air volume is also different. There are four methods to calculate the air volume of UV photo oxygen purifier

1. Calculate the air volume according to the hood

The plant area is large, but the source area of waste gas is relatively small, and the exhaust emission is concentrated. Then, a gas collecting hood can be installed above the source of waste gas, and the air volume can be calculated according to the area of the hood. The width of the hood is generally 800mm@0mmP0mm There are three kinds of specifications, and the length of collecting hood per meter is calculated as 2000-4000m3 / h, which has ideal ventilation effect. N meter length multiplied by 2000-4000m3 / h is the total air volume of the purifier.

2. Calculate according to the ventilation rate of the room

There is no way to effectively collect the odor in the workshop, and the ventilation system has not been installed, so the odor can not be effectively collected. The odor can only be extracted from the whole room for treatment. In this case, the air volume can be calculated according to the total volume of the plant. The volume is obtained by multiplying the length, width and height of the plant. The total air volume of the purifier is obtained by multiplying the volume by the number of air changes. Some of the ventilation times are 6-8, 20-30 and 100-150.

The selection of ventilation frequency depends on the concentration of exhaust gas and the desired ventilation effect. The concentration of waste gas is high, and if you want the indoor air circulation effect to be good, generally increase the air exchange rate to calculate the air volume. However, with the increase of air volume, the cost of air duct, fan and purifier will also increase.

3. According to the air volume of the fan

If the ventilation system has been arranged and there are existing fans, then the total air volume of the photodegradator is the total air volume according to the air volume of all fans. Generally, the air volume parameters are written on the fan nameplate. Select the air volume of purifier according to the maximum air volume of fan parameters.

4. Calculate the air volume according to the air duct

There is a ventilation system, but I don't know the air volume of the fan. Only the motor or the name plate has disappeared. This situation can be calculated according to the existing duct and the size of the duct. Some users will say that the calculation will not be accurate. Environmental protection equipment installation engineering is based on the combination of theoretical knowledge and practical experience.

It is very difficult to do it only by theoretical knowledge and without actual combat experience. Generally, the calculated air volume is selected for the larger model, and the difference is not too far.
