With the continuous development of economy, the scope of the use of ventilation equipment is constantly expanding, and the role of the equipment can not be ignored. With the progress of science and technology, the technical level of all walks of life is also constantly improving. The ventilation equipment is no exception, the equipment is becoming more and more perfect, but the production process is always changing, and the dust and harmful gas in the use of the equipment affect the safety of the ventilation pipeline.

廚房排煙管道,煤氣與天然氣管道的改造需要慎重。這兩種管道因受房屋結(jié)構(gòu)的限 制，一般不讓隨意改動。如果不得不改時，經(jīng)過物業(yè)公司的同意。改動時，由于較強(qiáng)，同時為方便日后的維修，通常由煤氣、天然氣公司或物業(yè)公司指定的公司負(fù)責(zé)改動。濟(jì)南排煙管道的煙道從建筑結(jié)構(gòu)設(shè)計(jì)來看由于有主、副煙道之分是不能隨意橫向改動的，否則會影響排煙并有倒灌的可能，而為了美觀將煙道口上下移動則不會有不好影響。

Kitchen exhaust pipe, gas and natural gas pipe transformation need to be careful. Due to the limitation of the building structure, these two kinds of pipes are generally not allowed to be changed at will. If you have to change, after the property company's consent. When making changes, due to its strong strength and for the convenience of future maintenance, the company designated by the gas company, natural gas company or property management company is usually responsible for making changes. From the architectural structure design point of view, the flue of Jinan smoke exhaust pipeline can not be changed horizontally because of the main and auxiliary flue, otherwise it will affect the smoke exhaust and have the possibility of backflow, and for the sake of beauty, moving the flue up and down will not have a bad effect.

在通風(fēng)設(shè)備的選擇時要對各種不利條件進(jìn)行考慮，以及是不是有完善的維修制度等，這些都要求著要不斷研發(fā)和提高新工藝，改造舊的工藝，使得通風(fēng)管道能夠改善不好的條件使之更好的應(yīng)用。

In the selection of ventilation equipment, all kinds of adverse conditions should be considered, as well as whether there is a perfect maintenance system, which requires continuous research and development and improvement of new technology, transformation of the old technology, so that the ventilation pipe can improve the bad conditions, so that it can be better applied.

對于使用的環(huán)境粉塵多的環(huán)境，要根據(jù)不同的粉塵情況采取不同的通風(fēng)設(shè)備和設(shè)計(jì)良好的通風(fēng)系統(tǒng)，以此來提高設(shè)備的穩(wěn)定性和可用性。首先看煙機(jī)的形式，如果是西式煙機(jī)（多為金字塔型）一般煙道的走向?yàn)榇怪毕蛏希饧硬讳P鋼煙道裝飾板，煙道口可改入吊頂內(nèi)，如果是中式煙機(jī)由于煙道導(dǎo)管外一般無裝飾板，則煙道口需改在吊頂下適當(dāng)位置，以便煙道導(dǎo)管經(jīng)裝飾板或從煙機(jī)吊柜內(nèi)同煙機(jī)連接。

In order to improve the stability and availability of the equipment, different ventilation equipment and well-designed ventilation system should be adopted according to different dust conditions. First of all, look at the form of the flue gas machine. If it is a western type flue gas machine (mostly pyramid type), the general direction of the flue is vertical upward, plus stainless steel flue decorative plate, the flue port can be changed into the ceiling. If it is a Chinese type flue gas machine, because there is no decorative plate outside the flue duct, the flue port should be changed to a proper position under the ceiling, So that the flue duct can be connected with the flue gas machine through the decorative plate or from the flue gas machine cabinet.
