油煙凈化器配套風機怎么選擇合適的?

來源:http://www.winetypeswiki.com/     發布時間:2022-12-23  

油煙凈化的目的是為了排放,因此嚴格地說,選擇風機的目的就是要確保風量的排放。工程現場中風機的選擇是個,存在很多誤區。
The purpose of lampblack purification is to discharge, so strictly speaking, the purpose of fan selection is to ensure the discharge of air volume. The selection of wind turbine in the project site is a key point, and there are many misunderstandings.
風機的作用就是要把經過油煙凈化器凈化后的煙氣排到室外去,但是要保證風量,先要確保風機的壓力能夠克服通風系統的阻力,否則無論風機標多少風量,*終都達不到理想的抽風效果。選擇風機時,光是看風機的風量是不夠的。
The function of the fan is to discharge the smoke purified by the lampblack purifier to the outside, but to ensure the air volume, first ensure that the pressure of the fan can overcome the resistance of the ventilation system, otherwise, no matter how much air volume the fan is marked, * will not achieve the ideal ventilation effect. When selecting a fan, it is not enough to just look at the air volume of the fan.
典型的風機參數圖如下:
Typical fan parameter diagram is as follows:
可知,不同的風機特性位于坐標不同的位置,使用者根據廚房爐頭的數量確定風量的大小,然后再根據管道的大小確定風速(廚房排煙管道的風速一般選擇在10-13米/秒),再由風速根據管道的長度、彎頭的數量、凈化器的阻力,算出推算系統的總阻力,然后從“Y”坐標選擇風機的全壓,再從“X”坐標選擇風量參數,兩條線的交錯點附近確定一條風機曲線,對應一個風機型號,這個就是適合的風機。
It can be seen that different fan characteristics are located at different locations in different coordinates. The user determines the air volume according to the number of kitchen burners, and then determines the wind speed according to the size of the duct (the wind speed of kitchen smoke exhaust duct is generally 10-13 m/s). Then, the total resistance of the system is calculated according to the length of the duct, the number of elbows, and the resistance of the purifier. Then, the full pressure of the fan is selected from the "Y" coordinate, Then select the air volume parameter from the "X" coordinate, and determine a fan curve near the intersection point of the two lines, corresponding to a fan model, which is the appropriate fan.
那么如何確定系統的阻力呢?按照理論計算比較復雜,簡單的經驗依據就是:
So how to determine the resistance of the system? The theoretical calculation is relatively complicated, and the simple empirical basis is:
濟南油煙凈化器
直管壓損:5pa/米
Pressure loss of straight pipe: 5pa/m
彎頭或變徑壓損:30pa/個
Pressure loss of elbow or reducer: 30pa/piece
靜電油煙凈化器壓損:200pa/臺
Pressure loss of electrostatic lampblack purifier: 200pa/set
煙罩的抽風口壓損:200pa/個
Pressure loss at exhaust port of smoke hood: 200pa/piece
爐頭數:8個
Number of furnace heads: 8
如果20米風管,彎頭變徑5個,加上煙罩的壓損200pa和科藍油煙凈化器的壓損200pa,保持動壓200pa,總壓損耗約為:
If 20 meters of air duct, 5 elbows are reduced, the pressure loss of smoke hood is 200pa, and the pressure loss of Kelan oil smoke purifier is 200pa, the dynamic pressure is maintained at 200pa, and the total pressure loss is about:
20*5+5*30+200+200+200=850pa,取風機的壓力為1000pa。
20 * 5+5 * 30+200+200+200=850pa, and the pressure of the intake fan is 1000pa.
8個爐頭風量為1600立方米,取風機的風量為1800立方米。
The air volume of 8 burners is 1600 m3, and the air volume of air intake fan is 1800 m3.
那么根據的縱橫坐標,可選6.3H和5.6H(兩者的性能有重疊部分)。假設選用6.3H,再看,根據全壓和風量,選擇800轉比較合適。
According to the vertical and horizontal coordinates of, 6.3H and 5.6H can be selected (their performance overlaps). Assuming 6.3H is selected, 800 rpm is appropriate according to the total pressure and air volume.
