The purification efficiency of high-altitude exhaust gas purification equipment can reach 60%-70%, while that of low-altitude exhaust gas purification equipment can reach more than 95%. However, the two kinds of tail gas purifier equipment can meet the requirements of national environmental protection emission standards.

　　高空排氣凈化器的設(shè)備在排放前需要將凈化后的氣體送到高空，因此需要在排氣凈化器的出口安裝排煙和排氣管。該低空排煙凈化器可將凈化后的氣體直接排放到大氣中，因此無需在出口制造排煙管道。

　　The equipment of high altitude exhaust purifier needs to send the purified gas to high altitude before discharging, so it is necessary to install smoke exhaust and exhaust pipe at the outlet of the exhaust purifier. The low-altitude smoke exhaust purifier can directly discharge the purified gas into the atmosphere, so there is no need to manufacture smoke exhaust pipe at the exit.

　　山東煙氣凈化凈化周期長，每次清洗維護時間快。不同類型的設(shè)備有不同的清洗周期和清洗方法。在正常情況下，正常的清洗保養(yǎng)并不會影響餐廳的正常運營，但是保養(yǎng)周期的長短以及每次保養(yǎng)的勞動強度和故障程度將是顧客選擇凈化器的重要標準。間隔1個月以上的清洗周期和每次不超過1小時的清洗維護時間是普通排煙凈化設(shè)備的技術(shù)難點標準。然而，高性能的排煙凈化設(shè)備基本可以清洗2個月以上，山東排煙凈化一次僅需半小時左右。

　　Shandong flue gas purification and purification cycle is long, each cleaning and maintenance time is fast. Different types of equipment have different cleaning cycles and methods. Normally, the normal cleaning and maintenance will not affect the normal operation of the restaurant, but the length of the maintenance cycle and the labor intensity and failure degree of each maintenance will be the important criteria for customers to choose purifiers. Cleaning cycle with interval of more than one month and cleaning maintenance time of less than one hour at a time are the technical difficult standards of common smoke exhaust purification equipment. However, high-performance flue gas purification equipment can basically be cleaned for more than 2 months, and the flue gas purification in Shandong only takes about half an hour at a time.

　　山東煙氣凈化研究表達:煙氣中含有多種對人體有害的化學成分，具有肺毒性、免疫毒性、遺傳毒性、致癌性、誘變性等。

　　Research and expression of flue gas purification in Shandong Province: There are many harmful chemical components in flue gas, which are pulmonary toxicity, immunotoxicity, genetic toxicity, carcinogenicity, mutagenicity and so on.

　　1. 各風道連接處應(yīng)采取防漏風措施，保證排煙凈化器的輸送。

　　1. The air leakage prevention measures should be taken at the connecting points of each air duct to ensure the conveyance of the smoke exhaust purifier.

　　2. 變直徑風管與排煙凈化器的進、出口相結(jié)合，應(yīng)保證通順，以保證安裝的傳動效果。

　　2. Combining the variable diameter air duct with the inlet and outlet of the smoke exhaust purifier, the fluidity should be ensured to ensure the transmission effect of the installation.

　　3.因此，在設(shè)置繁殖器風道時，必須采用軟組合。整定操作時振動不正常。

　　3. Therefore, the soft combination must be adopted when the breeder duct is set up. Abnormal vibration during setting operation.

　　4. 為了保證感染的真實性，個人故意設(shè)置風機風量的虛假計劃風量。3 .排煙凈化器應(yīng)在計劃風量內(nèi)，用戶可使用變頻器控制風機或在風機出口安裝空氣調(diào)節(jié)閥裝置以完成。

　　4. In order to ensure the authenticity of the infection, the individual intentionally sets the false planned air volume of the fan. 3. Smoke exhaust purifier should be specially designed within the planned air volume. Users can use frequency converter to control the fan or install air-conditioning valve device at the outlet of the fan to complete.
