濟南排煙罩是用于酒店、餐廳廚房的一種排煙裝置，其作用既可以補充一定數(shù)量的新風(fēng)，一方面可以平衡氣壓，避免廚房負(fù)壓過大，又可以降低廚房內(nèi)的溫度，改善工作環(huán)境。但是市面上排煙罩的種類有好多種，選擇一款適合自己廚房的才是重要的。
Jinan smoke exhaust hood is a smoke exhaust device used in hotel and restaurant kitchens. It can not only supplement a certain amount of fresh air, but also balance the air pressure, avoid excessive negative pressure in the kitchen, reduce the temperature in the kitchen and improve the working environment. But there are many kinds of smoke hoods on the market, and it is important to choose one that is suitable for your kitchen.
1、密閉罩
1. Airtight cover
污染源全部密閉在罩內(nèi)，其優(yōu)點排風(fēng)量小，可有效控制有害物，不受環(huán)境的影響，但影響操作，主要用于控制要求高的場合，危害比較的的氣體或煙塵。在食品廠或廚房的自動化生產(chǎn)線上應(yīng)用較多。自動連續(xù)電炸鍋，自動連續(xù)烘焙設(shè)備都是在這種煙罩里面工作。
All pollution sources are enclosed in the hood, which has the advantage of small exhaust air volume, and can effectively control harmful substances without being affected by the environment, but it affects the operation. It is mainly used in places with high control requirements to eliminate harmful gases or smoke and dust. It is widely used in automatic production lines of food factories or central kitchens. Automatic continuous electric fryer and automatic continuous baking equipment are all working in this kind of smoke hood.
2、柜式排煙罩
2. Cabinet type smoke exhaust hood
柜式排煙罩有一面敞開用于人工操作，其他面均密封，敞開面保持一定的吸風(fēng)速度，以保證柜內(nèi)有害物不逸出，主要應(yīng)用與實驗室。
Cabinet type smoke exhaust hood has one side open for manual operation, and other sides are sealed. The open side maintains a certain air suction speed to ensure that harmful substances in the cabinet do not escape. It is mainly used in laboratories.
3、外部吸氣罩
3. External suction hood
外部吸氣罩位于煙氣源附近，靠近煙口的抽吸作用將煙氣吸入煙罩內(nèi)。對生產(chǎn)操作影響小，安裝維護方便，但增加了對周圍空氣的吸入，排風(fēng)量大，效率低，控制有害物能力較差，主要用于因工藝要求或操作條件有限不能將污染物密閉的場合。
The external suction hood is located near the smoke source, and the smoke is sucked into the hood by the suction function near the smoke outlet. It has little impact on production and operation, and is easy to install and maintain, but it increases the intake of surrounding air, with large exhaust volume, low efficiency, and poor ability to control harmful substances. It is mainly used in situations where pollutants cannot be closed due to process requirements or limited operating conditions.
4、接收式排風(fēng)罩
4. Receiving exhaust hood
接收式排風(fēng)罩的罩口直接朝向煙氣流的運動方向，對準(zhǔn)污染源運動方向，控制煙氣的擴散。廚房斗式吊掛排煙罩就是接收自然抬升煙氣的。
The hood opening of the receiving exhaust hood directly faces the movement direction of the flue gas flow and is aligned with the movement direction of the pollution source to control the diffusion of the flue gas. The bucket type hanging smoke exhaust hood in the kitchen is designed to receive naturally raised smoke.
5、吹吸式排煙罩
5. Blowing and sucking smoke exhaust hood
吹吸式排煙罩由吸氣罩和吹出氣流組合而成的，抗外界氣流擾動能力強，控制效果能力強，效果好，不影響工藝操作，但需要增加吹風(fēng)管道。主要作用來提高排煙效果，吸氣罩離煙氣源較遠(yuǎn)或者附近有氣流涌動，僅靠吸風(fēng)控制煙氣較困難的場合。
The blowing and suction smoke exhaust hood is composed of the suction hood and the blowing air flow, which has strong resistance to external air flow disturbance, strong control effect and good effect, and does not affect the process operation, but needs to add blowing pipes. It is mainly used to improve the smoke exhaust effect. The suction hood is far from the smoke source or there is airflow surge nearby, and it is difficult to control the smoke only by suction.
The above are some common smoke hoods in catering kitchens. Please consult our website for specific performance parameters and prices of various smoke hoods http://www.heblc.com Staff, we will serve you wholeheartedly!
