Please refer to Fig. 1 and Fig. 2, the intelligent multifunctional environmental protection device provided by the present invention mainly includes: a
複數感測器經組態連接至該安全濃度氣體14,包括:一氧感測器11、一氮氧化物感測器12以及一碳氫化合物感測器13,當該外部空氣21稀釋該廢氣3以形成該安全濃度氣體14時,該氧感測器11計算該安全濃度氣體14中該外部空氣21的氣體濃度(gas concentration),而該氮氧化物感測器12則計算該安全濃度氣體14中該氮氧化物31的氣體濃度,使該碳氫化合物感測器13計算該安全濃度氣體14中該揮發性有機化合物32的氣體濃度。
A plurality of sensors are configured to be connected to the
該送風機2係配合該安全濃度氣體14的一濃度值來變更該送風機2之轉速的方式控制該外部空氣21(outside air)的送風量,為該控制器7其根據該氧感測器11
的計量值控制使用該送風機2送風之送風量,而控制從該送風機2送進該混合室1之該外部空氣21的濃度來調整該安全濃度氣體14的配合濃度。
The
該加熱室5為接收該安全濃度氣體14輸入該加熱室5,以將指定為一被加數(summand)的該安全濃度氣體14,經由指定為一第一加數(first addend)經由具有一第二溫度的一第一加熱源51(first heating source)與指定為一第二加數(second addend)且具有一第三溫度的一第二加熱源52(second heating source)進行升溫,使該被加數、該第一加數與該第二加數加總獲得被指定為一總和且輸出具有一第四溫度的一加熱氣體53(heating gas);該第二溫度為設置於該第一加熱源51內的一溫度感測器偵測,該溫度感測器並連接至該控制器7量測溫度(measure temperature)。該第三溫度為設置於該第二加熱源52內的一溫度感測器偵測,該溫度感測器並連接至該控制器7量測溫度。

The
本實施例中在執行多個加溫任務時,該控制器7不採用先啟動先停止加溫的原則,而是根據該第二加熱源52為第一加溫順序的優先順序來調度。
In this embodiment, when performing multiple heating tasks, the controller 7 does not adopt the principle of starting first and stopping heating first, but schedules according to the priority order that the
該控制器7能透過確定多個加溫的優先順序以及規定的加溫截止時間,確定該第四溫度預設的加溫上限,因該第四溫度能為一固定值或一浮動值,當該第四溫度將溫度維持在一已知目標溫度時,該第四溫度所期望維持之溫度週期或溫度範圍的任何變化並非不正常狀況。 The controller 7 can determine the preset heating upper limit of the fourth temperature by determining a plurality of heating priorities and a prescribed heating cut-off time, because the fourth temperature can be a fixed value or a floating value, when While the fourth temperature maintains the temperature at a known target temperature, any variation in the temperature cycle or temperature range over which the fourth temperature is expected to be maintained is not an abnormal condition.
如果該第四溫度的溫度範圍保持比期望的溫度週期低得多或高得多,同時維持該溫度,則此可能是因一外部熱源(例如,該第二加熱源52的該第三溫度)所造成。 If the temperature range of the fourth temperature remains much lower or higher than the desired temperature cycle while maintaining the temperature, this may be due to an external heat source (e.g., the third temperature of the second heating source 52) caused.
如該第四溫度的輸出值預設為400℃,在該加熱室5的該安全濃度氣體14的溫度為30℃,此時該VOC觸媒61未啟動,無法輸出熱能至該第二加熱源52,則該第一加熱源51加溫到370℃輸出至該加熱室5。在5分鐘後該VOC觸媒61放熱產生400℃熱能,則該第二加熱源52輸出370°C的熱能至該加熱室5,同時該控制器7關閉第一加熱源51的電源,以節省能源,此為該第四溫度大於該第三溫度時該控制器7的操作模式。
If the output value of the fourth temperature is preset to 400° C., the temperature of the
上述說明,使得本實施例根據加溫優先順序對該第一加熱源51、該第二加熱源52、該第一加熱源51與該第二加熱源52加溫的先後順序進行調度,並使調度後的加溫條件以滿足升溫到該第四溫度,其中,該第四溫度在加溫時不存在該第一加熱源51或該第二加熱源52的加溫時間衝突,所述時間衝突為該第一加熱源51與該第二加熱源52在
加溫時間序列上存在重疊的部分。透過上述調度處理,能夠以該第二加熱源52為指定優先(assignment priority)順序來維持各加溫級別順序的執行,盡可能地減少對該第一加熱源51的加溫時間與減少加溫次數,從而能夠讓該第二加熱源52指定優先順序被執行加溫運用,而該第一加熱源51根據加溫任務優先順序配合該第二加熱源52對執行多個任務的先後加溫順序進行調度。
