排煙罩是為飲食開發(fā)的大型飲食油煙凈化設(shè)備，它是依據(jù)傳質(zhì)雙模理論、選用磕碰、冷凝、吸收過濾的技術(shù)，凈化烹調(diào)過程中發(fā)作的油霧、氣味等有害物質(zhì)。排煙罩在凈化設(shè)備中設(shè)置了氣體收集、洗刷、反應(yīng)吸收、洗刷劑循環(huán)、機(jī)械過濾器、氣體運(yùn)送、降溫防火等結(jié)構(gòu)單元，是集氣體的收集-凈化-運(yùn)送于一體；排煙罩是集-消防-于一體的多功能油煙凈化設(shè)備。那么商用廚房?jī)?nèi)的排煙罩的作業(yè)原理是什么呢？下面燊赫通風(fēng)小編就來給大家大致介紹一下。
The smoke hood in the commercial kitchen is a large-scale cooking fume purification equipment specially developed for the catering industry. It is based on the dual-mode theory of mass transfer, using the technology of bump, condensation, absorption and filtration to purify the harmful substances such as oil mist and smell during the cooking process. The fume hood is equipped with gas collection, washing, reaction absorption, detergent circulation, mechanical filter, gas transportation, cooling and fire prevention and other structural units in the purification equipment, which is a multi-functional and efficient fume purification equipment integrating gas collection, purification and transportation; the fume hood is a multi-functional and efficient fume purification equipment integrating environmental protection, fire protection and energy conservation. So what is the working principle of the smoke hood in the commercial kitchen? Let's have a brief introduction of the ventilation system.
1、通風(fēng)能力：
1. Ventilation capacity:
（1）配消聲器降低風(fēng)機(jī)噪聲。
(1) Equipped with muffler to reduce fan noise.
（2）分外制作的專用高速轉(zhuǎn)速風(fēng)機(jī)、壓力高、風(fēng)量大，足以打敗凌亂管道的阻力。它的通風(fēng)效果好。
(2) Specially made high-speed fan with high pressure and large air volume is enough to defeat the resistance of disordered pipes. It has good ventilation effect.
（3）分外電機(jī)耐高溫、耐水汽，并且它的可靠性也高。
(3) Besides, the motor is resistant to high temperature, water and steam, and its reliability is also high.
2、凈化原理：
2. Purification principle:
（1）剩下少量的油煙再進(jìn)入過濾桶進(jìn)行二次凈化，固態(tài)顆粒沉積在濾料上，廢油精槽道流入油盒。濾筒內(nèi)濾料可便當(dāng)?shù)奶鎿Q。
(1) A small amount of the remaining oil fume enters the high-efficiency filter barrel for secondary purification, and the solid particles are deposited on the filter material, and the waste oil fine channel flows into the oil box. The filter material in the filter cartridge can be easily replaced.
（2）在風(fēng)機(jī)的抽吸力效果，油煙進(jìn)入濾油柵進(jìn)行初級(jí)凈化，大多數(shù)油煙的灰粒和液滴被截留，費(fèi)油順油道流入油盒，顆粒沉積在金屬濾油柵上。濾油柵可以便當(dāng)?shù)娜∠虑逑础?/div>
(2) In the suction effect of the fan, the oil fume enters the oil filter screen for primary purification, most of the ash particles and liquid drops of the oil fume are intercepted, the waste oil flows into the oil box along the oil passage, and the particles are deposited on the metal oil filter screen. The oil strainer can be easily removed and cleaned.
（3）通過排煙罩凈化后的空氣經(jīng)風(fēng)機(jī)、氣管排向室外。
(3) The purified air through the smoke hood is discharged to the outdoor through the fan and air pipe.
廚房排煙罩
Kitchen smoke hood
在人們的日常生活中，每家的廚房都需要用廚房排煙罩來保障廚房空氣的清新，所以廚房排煙罩為局部排煙的一種形式。在設(shè)計(jì)過程必須要確保罩口風(fēng)速的穩(wěn)定。通過罩口風(fēng)速計(jì)算風(fēng)量，從而得到廚房排煙罩的所需的總風(fēng)量。通過總風(fēng)量計(jì)算確定廚房排煙管道的橫截面積。再根據(jù)廚房整體高度確定管道高度。
In people's daily life, every kitchen needs to use the kitchen smoke hood to ensure the fresh air in the kitchen, so the kitchen smoke hood is a form of local smoke exhaust. In the design process, it is necessary to ensure the stability of the wind speed at the hood opening. The air volume is calculated by the air speed at the hood mouth, so as to obtain the total air volume required by the kitchen smoke hood. The cross-sectional area of kitchen exhaust pipe is determined by the total air volume calculation. Then determine the height of the pipe according to the overall height of the kitchen.
廚房排煙罩安裝切記漏油與漏風(fēng)的處理。處理時(shí)所有材料一定要選用防火材料。在管道安裝過程中一定要設(shè)置防火閥，確保廚房排煙罩在使用過程中發(fā)生火災(zāi)后防火閥應(yīng)該自動(dòng)閉，防止火燒連營的現(xiàn)象發(fā)生。
Remember to deal with the oil and air leakage when installing the smoke hood in the kitchen. All materials must be fire-proof when handling. In the process of pipeline installation, fire damper must be set to ensure that the fire damper should be closed automatically after the fire occurs in the use of kitchen smoke hood, so as to prevent the phenomenon of continuous fire.
廚房排煙罩選用風(fēng)機(jī)時(shí)應(yīng)準(zhǔn)確計(jì)算風(fēng)管的風(fēng)速、流量、風(fēng)阻，這樣在選擇風(fēng)機(jī)過程中能準(zhǔn)確的確定風(fēng)機(jī)的風(fēng)量、風(fēng)壓、電機(jī)功率。從而達(dá)到的良好效果，對(duì)日常經(jīng)營中減低成本起到重中之重的作用。
When selecting fans for kitchen smoke hood, the wind speed, flow and wind resistance of the air duct shall be accurately calculated, so that the air volume, wind pressure and motor power of the fans can be accurately determined in the process of selecting fans. So as to achieve the good effect of energy saving and play a key role in reducing costs in daily operation.
