醫(yī)療廢棄物的前期處理、收集和分類由醫(yī)療機(jī)構(gòu)工作人員在醫(yī)療廢棄物產(chǎn)生源如門(mén)診部、病房、手術(shù)室、實(shí)驗(yàn)室等地完成。醫(yī)療廢棄物焚燒時(shí)，用車將盛裝醫(yī)療廢棄物的紙箱送到焚燒廠的冷藏室儲(chǔ)存，通過(guò)自動(dòng)輸送機(jī)將醫(yī)療廢棄物倒入焚燒爐進(jìn)料口；計(jì)量后的垃圾進(jìn)入焚燒爐中，在900～1100℃高溫下，垃圾焚燒成灰燼；為了適應(yīng)醫(yī)療廢棄物熱值的變化，保證燃燒溫度和效果，在燃燒室設(shè)置了輔助燃燒器。焚燒爐出口的高溫?zé)煔?，進(jìn)入急冷塔快速降溫；降溫后的煙氣在煙道中與消石灰、反應(yīng)助劑等反應(yīng)，使煙氣中的有害氣體被除去，然后通過(guò)布袋除塵器而被除去；凈化后的氣體由引風(fēng)機(jī)排入大氣。焚燒爐的爐渣、急冷塔產(chǎn)出的飛灰及布袋除塵器排出的反應(yīng)物進(jìn)行收集另行處理。該醫(yī)療廢棄物焚燒處理技術(shù)與其它處理技術(shù)相比較，具有無(wú)害化*、減量比高，焚燒效果好等顯著優(yōu)點(diǎn)。

The primary processing, collection and classification of medical waste shall be conducted by staffs of medical institutes at the source of such wastes, such as out-patient departments, sickrooms, operation rooms and laboratories ,etc. When medical waste is being incinerated, the carton box shipping it is to be stored in the freezer of the incineraton site by a dedicated vehicle and then medical waste is poured into the feeding port of incinerator through the automatic conveyer. After being metered, waste goes into the incinerator. Under the high temperature of 900-1100℃, waste is burned to dust. The combustion chamber is equipped with auxiliary boiler for adapting to the change of medical waste calorific value and assuring burning temperature and effect. High-temperature smoke at incinerator outlet enters quench tower and cools rapidly. The cooled fume reacts with lime hydrate and auxiliary agent in flue to eliminate noxious gas with bag filter. Then the purified gas is injected into the atmosphere by draft fan. Slag of incinerator, fly ash of quench tower and reactant of bag-filter should be collected and processed separay. Compared with other process, the medical waste incineration process technology has many obvious advantages, such as ultimate harmless treatment, high decrement rate and effective incineration performance.
