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.

厨房排烟管道,煤气与天然气管道的改造需要慎重。这两种管道因受房屋结构的限 制，一般不让随意改动。如果不得不改时，经过物业公司的同意。改动时，由于较强，同时为方便日后的维修，通常由煤气、天然气公司或物业公司指定的公司负责改动。济南排烟管道的烟道从建筑结构设计来看由于有主、副烟道之分是不能随意横向改动的，否则会影响排烟并有倒灌的可能，而为了美观将烟道口上下移动则不会有不好影响。

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.

在通风设备的选择时要对各种不利条件进行考虑，以及是不是有完善的维修制度等，这些都要求着要不断研发和提高新工艺，改造旧的工艺，使得通风管道能够改善不好的条件使之更好的应用。

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.

对于使用的环境粉尘多的环境，要根据不同的粉尘情况采取不同的通风设备和设计良好的通风系统，以此来提高设备的稳定性和可用性。首先看烟机的形式，如果是西式烟机（多为金字塔型）一般烟道的走向为垂直向上，外加不锈钢烟道装饰板，烟道口可改入吊顶内，如果是中式烟机由于烟道导管外一般无装饰板，则烟道口需改在吊顶下适当位置，以便烟道导管经装饰板或从烟机吊柜内同烟机连接。

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.
