Nowadays, with the improvement of people's living standards, the electrical equipment in the kitchen has become more and more, and the kitchen exhaust pipe is one of them. Do you know how to solve the problem when the smoke exhaust pipe of Jinan kitchen is damaged?

1、用精鹽勻稱撒在四周的池內壁，隨后用開水由上而下地清洗幾次，油漬便可去除。濟南廚房排煙管道水池四角的凹形槽可以用廢軟毛牙刷蘸一些細鹽粒來清洗，還可以用舊布縫紉一個小兜，裝進幾片廢料的香皂頭，泡上一點水后在蓄水池內腔上帶油漬的地區用勁刷兩下，后再用清水沖凈，油漬就沒有了。

1. Sprinkle salt evenly on the inner wall of the pool, and then wash it with boiling water from top to bottom several times, and the oil stains can be removed. The concave groove at the four corners of Jinan kitchen smoke exhaust pipe pool can be cleaned by dipping some fine salt particles with a waste soft bristle toothbrush. You can also sew a small pocket with an old cloth, put several pieces of waste soap into it, soak it in a little water, and then brush it twice in the oil stained area on the reservoir cavity, and then rinse it with clean water.

2、不銹鋼鍋非常容易沾上灰黑色的污漬，并且無法清洗。把家中很大的鍋中再加半鍋上下的冷水，并資金投入一些菠蘿皮，再把新號的鍋逐一裝進去，在灶具上加溫燒開一段時間，直到制冷之后取出，就能發覺這種鍋會明亮如新口。

2. Stainless steel pots are very prone to gray black stains and cannot be cleaned. Add half of the top and bottom cold water to the big pot at home, and put some pineapple peel into the pot one by one. Heat the cooker and boil it for a period of time until it is taken out after refrigeration. You can find that this kind of pot will be as bright as new mouth.

濟南廚房排煙管道安裝廚房內送、排風口時應按灶具的具體位置加以考慮，不要讓送風射流擾亂灶具的排風性通。確定送風出口的出口風速時，在距地2m左右時的區域風速<0.25m/s較為理想。送風口應沿排風罩方向布置，離開罩子前方小0.7m，而排風口距排風罩越遠越好。

Jinan kitchen exhaust pipe installation kitchen air supply, exhaust outlet should be considered according to the specific location of the stove, do not let the air supply jet disturb the ventilation performance of the stove. When determining the outlet wind speed of the air supply outlet, the regional wind speed less than 0.25m/s at about 2m above the ground is ideal. The air supply outlet should be arranged along the direction of the exhaust hood, 0.7m away from the front of the hood, and the farther the exhaust outlet is from the exhaust hood, the better.

廚房排煙管道的水平段不宜太長，一般水平遠距離不應超過15m并且要有百分之2以上的坡度，水平末端設活接頭，以方便清理油垢。排風速度按規范不得低于10m/s，以防風速過低使油附著于煙道上，接排風罩的支管應設風量調節閥。

The horizontal section of the kitchen smoke exhaust pipe should not be too long. Generally, the horizontal distance should not exceed 15m, and there should be a slope of more than 2%. The horizontal end should be provided with a movable joint to facilitate the cleaning of oil dirt. The exhaust speed shall not be lower than 10m / s according to the specification, so as to prevent the oil from adhering to the flue due to too low wind speed. The branch pipe connecting the exhaust hood shall be equipped with air volume regulating valve.
