The middle of the ventilation duct and the oil fume exhaust duct belong to the pipeline, but the key difference is in the main purpose. The oil fume exhaust duct is used as the pipeline to remove smoke and dust, and the key function of the ventilation duct is the exhaust and smoke exhaust system, which is common in one or several rooms or machinery and equipment. The differences between them are mainly reflected in their characteristics.

After the installation of the air duct, ensure that the surface is clean and free of other residues, and the ventilation air duct located outdoors must be snow proof, waterproof and rainproof. When crossing the regeneration deformation joint, the ventilation air duct must be added with waterproof casing according to the design scheme, and the gap between the ventilation air duct and waterproof casing must be blocked with filler carefully. What are their characteristics? How can we fully prepare for the work? The design scheme of ventilation duct system software in Shandong Province, what matters must be paid attention to in the transportation and maintenance of ventilation duct, the main purpose of ventilation duct, etc. The key functions of ventilation duct mentioned therein include natural ventilation, smoke exhaust system, transportation and other main purposes.

山東通風(fēng)管道

Shandong ventilation duct

次序式煙道橫截面上由2個(gè)并排矩形框排風(fēng)管組成，豎直穿越重生各樓。次煙道在住房各層中設(shè)一聯(lián)接排油煙機(jī)的進(jìn)氣口，山東省通風(fēng)管道的次煙道與主煙道距進(jìn)氣口一定距離處相匯，主煙道層有一補(bǔ)出風(fēng)口。其基本原理是根據(jù)抽油煙機(jī)將煙塵送入次煙道中，用抽油煙機(jī)驅(qū)動(dòng)力和油煙溫度上水的浮力使油煙升高一段距離后再進(jìn)到主煙道排出來(lái)平屋面。

The cross section of the sequential flue is composed of two side-by-side rectangular frame exhaust ducts, which vertically pass through the regeneration buildings. The secondary flue is provided with an air inlet connecting the range hood in each floor of the house. The secondary flue of the ventilation pipeline in Shandong Province meets with the main flue at a certain distance from the air inlet, and the main flue layer is provided with a supplementary air outlet. The basic principle is that the smoke and dust is sent into the secondary flue according to the range hood, and the oil smoke is raised for a certain distance by the driving force of the range hood and the buoyancy of the oil smoke temperature and water, and then into the main flue and discharged out of the flat roof.

由一個(gè)簡(jiǎn)易的矩形框排風(fēng)管組成，豎直穿越重生各層住房，在各層住房中留出一個(gè)聯(lián)接抽油煙機(jī)的進(jìn)氣口，層由一個(gè)補(bǔ)出風(fēng)口補(bǔ)氣血。其基本原理是各層煙塵在抽油煙機(jī)的促進(jìn)下，將油煙排進(jìn)煙道中，因?yàn)闊焿m溫度的功效，在煙道中造成升高水的浮力，從出平屋面的通風(fēng)口將煙塵排出來(lái)。

It is composed of a simple rectangular frame exhaust pipe, which vertically passes through the houses on each floor of regeneration. An air inlet connected with the range hood is reserved in the houses on each floor, and an air outlet is used to supplement qi and blood. The basic principle is that each layer of smoke and dust will be discharged into the flue under the promotion of the range hood. Because of the effect of smoke and dust temperature, it will cause the buoyancy of rising water in the flue and discharge the smoke and dust from the vent out of the flat roof.
