Purification effect of oil fume purifier

It is inevitable to install fume purifier in restaurants, and the effect of fume purifier is a concern of many restaurant owners. Some people say that the fume purifier is not effective, but it is actually just a show. Some people say that the lampblack purifier has a good effect and the lampblack purification is very clean. What's going on here?

Installation of lampblack purifier

First of all, the purification effect of the lampblack purifier is definitely good, and the general visual inspection can achieve the effect of smoke-free discharge. Otherwise, the state will not introduce relevant policies, requiring catering units that emit lampblack to install lampblack purifiers.

So, what is the problem?

1. The purification effect of the purchased equipment has not reached the national standard.

At present, the national standard of oil fume emission is 2 mg/m3, and the purification efficiency of oil fume purifier needs to be above 80%. The landmark in the north, Shanghai, Guangzhou, Shenzhen and other regions is 1 mg/m3, and the purification efficiency of the oil fume purifier needs to reach more than 90% to meet it. It is recommended to choose a low-altitude electrostatic fume purifier, and the fume purification efficiency is over 90%.

2. The purchased equipment has quality problems.

A few hundred dollars can buy a lot of low-altitude electrostatic fume purifiers that claim to be more than 95%. After buying it, I found that the purification effect was very poor, so I labeled all the lampblack purifiers as "invalid". Generally speaking, the normal price of a low-altitude electrostatic fume purifier meeting the national standard is about 0.5- 1.2 yuan/air volume, which means that the price of a fume purifier with 4000 air volume is about 2000-4800, and that of a fume purifier with 6000 air volume is about 3000-7200. Buy a few hundred thousand, and you will know that the gap is obvious from the size, appearance and material.

3. The matching of the treatment air volume of the purchased oil fume purifier is unreasonable.

It is also very important to match the air volume of the fume purifier, but generally speaking, the seller of the fume purifier will help you match it well, and there will be no problem. However, some sellers have the phenomenon of "virtual standard", that is, selling low-volume fume purifiers according to high air volume, which leads to poor purification effect after purchase by buyers, so we should pay attention to the distinction.

4. The installation of the fume purifier is unreasonable.

Finally, the installation of the fume purifier. In fact, as long as you find a professional and experienced tin master to install it, there will generally be no problem.
