1，風(fēng)管式通風(fēng)：設(shè)備簡單，靈活方便，易于拆卸，但由于斷面小，隨著管路的加長，通風(fēng)阻力將增大。

1. Air duct ventilation: the equipment is simple, flexible and convenient, and easy to disassemble. However, due to the small section, the ventilation resistance will increase with the extension of the pipeline.

2，巷道式通風(fēng)：適用于有平行導(dǎo)坑的長隧道，特點(diǎn)是通過前面的橫通道，使正洞和平行導(dǎo)坑組成一個(gè)循環(huán)風(fēng)流系統(tǒng)，在平導(dǎo)坑口附近安裝通風(fēng)機(jī)，將污濁空氣由平導(dǎo)抽出，新鮮空氣由正洞流入，形成循環(huán)風(fēng)流。

2. Tunnel ventilation: It is applicable to long tunnels with parallel pilot tunnels. It is characterized by making the main tunnel and parallel pilot tunnels form a circulating air flow system through the front horizontal channel. A ventilator is installed near the opening of the horizontal pilot tunnel to draw out the dirty air from the horizontal pilot tunnel, and fresh air flows into the main tunnel to form a circulating air flow.

3，風(fēng)墻式通風(fēng)：利用隧道成洞部分空間，用磚砌或木板隔出一條風(fēng)道，代替大直徑風(fēng)管，以縮短風(fēng)管長度，而又能增大供風(fēng)量滿足通風(fēng)要求，該方式適用于縮短較長，又無平行導(dǎo)坑可供利用，而管道式通風(fēng)又難以全盤解決的情況。通風(fēng)管道常用鍍鋅鐵皮管道和不銹鋼管道，在酸霧排氣方面可進(jìn)行金屬管道噴塑處理再使用，也可以直接采用PP管道（防火性能不要求的情況下使用），部分小型排氣、送風(fēng)管道為節(jié)約成本，也可采用PVC、PPR管道作為風(fēng)管。

3. Air wall ventilation: use the part of the tunnel space to separate an air duct with brick or wood to replace the large-diameter air duct, so as to shorten the length of the air duct, and increase the air supply to meet the ventilation requirements. This method is applicable to the situation that the length of the air duct is longer, and there is no parallel pilot pit available, and the duct ventilation is difficult to solve completely. Galvanized iron sheet pipes and stainless steel pipes are commonly used for ventilation pipes. In the aspect of acid mist exhaust, metal pipes can be sprayed and reused, or PP pipes can be directly used (if the fire performance is not required). In order to save costs, some small exhaust and air supply pipes can also use PVC and PPR pipes as air pipes. Donglanglongke has been specialized in the processing and installation of air ducts for 15 years, and has rich experience and professional technology and equipment in this field, which will escort you in the aspects of ventilation and exhaust, smoke exhaust, exhaust, purification and dust removal, civil air defense, and fire protection pipelines.

通風(fēng)管道是為了使空氣流通，降低有害氣體濃度的一種市政基礎(chǔ)設(shè)施。通風(fēng)管，風(fēng)管制作與安裝所用板材、型材以及其他主要成品材料，應(yīng)符合設(shè)計(jì)及相關(guān)產(chǎn)品標(biāo)準(zhǔn)的規(guī)定，并應(yīng)用出廠檢驗(yàn)合格證明，材料進(jìn)場時(shí)應(yīng)按有關(guān)標(biāo)準(zhǔn)進(jìn)行驗(yàn)收。通風(fēng)管道按材質(zhì)分：一般有：鋼板風(fēng)管、鍍鋅板風(fēng)管、不銹鋼通風(fēng)管、玻璃鋼通風(fēng)管、塑料通風(fēng)管、復(fù)合材料通風(fēng)管、彩鋼夾心保溫板通風(fēng)管、雙面鋁箔保溫通風(fēng)管、單面彩鋼保溫風(fēng)管、涂膠布通風(fēng)管、礦用塑料通風(fēng)管等。

The ventilation pipe is a municipal infrastructure for air circulation and reducing the concentration of harmful gases. The plates, profiles and other main finished materials used for the production and installation of ventilation pipes and air ducts shall comply with the provisions of the design and relevant product standards, and the factory inspection certificate shall be applied. The materials shall be accepted according to relevant standards when entering the site. The ventilation pipes are divided by material: generally, they are: steel plate ventilation pipes, galvanized sheet ventilation pipes, stainless steel ventilation pipes, fiberglass ventilation pipes, plastic ventilation pipes, composite ventilation pipes, color steel sandwich insulation plate ventilation pipes, double-sided aluminum foil insulation ventilation pipes, single-sided color steel insulation ventilation pipes, coated plastic ventilation pipes, mining plastic ventilation pipes, etc.

通風(fēng)管道的應(yīng)用一般有：凈化系統(tǒng)送回風(fēng)管、空調(diào)通風(fēng)管、工業(yè)送排風(fēng)通風(fēng)管、消防排煙管道、餐飲排油煙管道、系統(tǒng)吸排風(fēng)管、礦用抽放瓦斯管、礦用涂膠布風(fēng)筒等。

The application of ventilation duct generally includes: purification system supply and return air duct, central air conditioning ventilation duct, industrial supply and exhaust air duct, fire smoke exhaust duct, catering oil smoke exhaust duct, environmental protection system suction and exhaust air duct, mine gas drainage pipe, mine adhesive coated cloth air duct, etc.
