第5頁 552155 五、發明說明（3) 内（如粗箭頭a所示），並因冷卻室1 2 0内的風扇1 3 2之轉動而被吹到散熱槽1 3 0上，故散熱槽1 3 0由較高溫水流中所吸收的熱，將隨著風扇1 3 2的轉動而經由出氣孔流出到冷卻室1 2 0之外面（如粗箭頭b所示）。是以，由散熱槽1 3 0處流出的水流已經變成冷水（因為所述較高溫水流之熱量有部份經由熱傳導傳給散熱槽 1 3 0，且散熱槽1 3 0由較高溫水流處所得到之熱量也隨風扇 1 3 2轉動而帶出冷卻室1 2 0之外面），而此冷水可再流入集水槽129中，並經由回流管126’引入熱交換器128内。然而，由於進入冷卻室1 2 0的外界空氣可能含有廢棄物，或者散熱槽1 3 0可能發生碎片脫落的狀況，因此由散熱槽1 3 0處流出的冷水可能含有廢棄物，故由散熱槽1 3 0處流出的冷水，在進入熱交換器1 2 8内之前，需先經由排水管1 2 6引入y形過濾裝置1 2 4内，此時y形過濾裝置1 2 4即發揮過濾廢棄物之功能，而將廢棄物留置於其内。Page 5 552155 V. Description of the invention (3) (as shown by thick arrow a) and blown to the heat sink 1 3 0 due to the rotation of the fan 1 32 in the cooling chamber 1 2 0, so the heat sink 1 3 0 The heat absorbed by the higher temperature water flow will flow out of the cooling chamber 1 2 0 through the air outlet as the fan 1 2 2 rotates (as shown by the thick arrow b). Therefore, the water flow from the heat sink 130 has become cold water (because part of the heat of the higher temperature water stream is transferred to the heat sink 1 3 0 through heat conduction, and the heat sink 1 30 is obtained from the higher temperature water stream. The heat is also taken out of the cooling chamber 12 (as the fan 1 32 rotates), and the cold water can flow into the water collecting tank 129 and be introduced into the heat exchanger 128 through the return pipe 126 '. However, since the outside air entering the cooling chamber 120 may contain waste, or debris may fall off from the heat sink 130, the cold water flowing from the heat sink 130 may contain waste, so the heat sink Before entering the heat exchanger 1 2 8, the cold water flowing out at 130 needs to be introduced into the y-shaped filter device 1 2 4 through the drainage pipe 1 2 6. At this time, the y-shaped filter device 1 2 4 is used to filter waste. Function of the product, leaving waste in it.

Description of the invention (9) The valve driver 3 1 2 includes an electric solenoid valve driver, a pneumatic valve driver or a hydraulic valve driver. The structure design of the drain valve device 3 1 0 shown in FIG. 3 is only an example of a valve suitable for discharging particulate matter from the y-shaped filter device 3 0, and other types of applicable valves may also be used in the present invention. In the above-mentioned automatic flushing y-shaped filtering device 3 0 0 proposed by the present invention, any system that intends to filter and waste by the automatic flushing y-shaped filter 3 300, such as wetness A scrubber (as shown in Figure 6) or a cooling water system (as shown in Figure 7) is a water stream containing the waste flowing through the elongated duct of the auto-washable y-shaped filter and device 300 3 0 4, as shown by the thick arrow in FIG. 3, as the water flows into the liquid inlet arm 3 0 3 of the elongated duct 3 4, the waste particles will be blocked by the filter 3 0 8 and left behind. In the above-mentioned filter 308 (here, the selection of the material and size of the filter 308 is usually related to the amount of water passing through the filter 308 and the size of the y-shaped filter device 300, respectively. As for the filter The selection of the size of the filter holes in 3 0 8 is related to the lower limit of the size of the waste to be pre-filtered), so that the water flow through the liquid outlet arm 3 0 5 is substantially free of particles. Under the normal operation of the wet scrubber or cooling water system and the filtering operation of the y-shaped filtering device 300, as shown in Figure 4, it can be seen that the amount of water Q2 at the outlet of the elongated duct 3 0 The inlet water quantity Q1 of 3 0 4 is equal. Moreover, the water pressure at the entrance of the extension duct 3 0 4 is greater than the water pressure at the exit of the extension duct 3 0 4 (so that water can flow from the entrance of the extension duct 3 0 4 to the extension Exit of the duct 3 0 4), and these two

第12頁 552155 五、發明說明（ίο) 之水壓差通常隨該濾器3 〇 8中所留滯的廢棄物量增加而降低（因為，該濾器3 〇 8中所留滯的廢棄物量增加，此二處之間的水流速率將減緩，其係代表此二處之水壓差降低了 )。是以，只要於該閥驅動器3 1 2中設定當此二處之水壓差（可由如圖六和圖七所示之入口壓力監測器8 2和出口壓力監測器8 3的水壓差得知）降低至一參考值，例如至少約 5 ps i (當此二處之水壓差降低至此參考值時，即代表該濾器3 0 8已被廢棄物堆積到該濾器3 0 8需要沖洗除去廢棄物顆粒或會影響到所述需過濾廢棄物的系統之正常運作的程度），即開啟該排洩閥門裝置3 1 0 (此時，在濕性洗祿器或冷卻水系統之排水管、該y形過濾裝置3 〇〇和回流管中的水流仍然持續流動循環），那麼由於該濾器殼體3 〇 2與該伸長導管3 0 4相連接的一端之水壓，遠較該閥門座接管3 〇 9 處之水壓為大（因為該濾器殼體3 0 2之形狀為前面所述之錐體）’故根據喷射原理，水流將由該濾器殼體3 〇 2與該伸長導管3 0 4相連接的一端往該閥門座接管3 〇 9之管口外喷出’因此就使得先前留滯在該濾器3 0 8的廢棄物顆粒，可隨著該沖洗水流由該閥門座接管3 0 9之管口處喷出到該淚器3 0 8之外而被收集到一納容器（未顯示）内。其中，在開啟該排洩閥門裝置3 1 0以沖洗該濾器3 0 8時，由該閥門座接管3 0 9處喷出的噴水量Q3係遠少於在該伸長導管3〇4之出口水量Q2，故該閥門裝置3 1 0之開啟並不會影響系統之正 :，作狀態。基本上該沖洗水流和廢棄物顆粗0持續從該冷閥門裝置灣出，一直到該遽器3 08内之廢棄物顆粒被Page 12 552155 V. The water pressure difference of the invention description (ίο) usually decreases with the increase of the amount of waste left in the filter 3 08 (because the amount of the waste left in the filter 3 08 increases, this The flow rate between the two places will slow down, which means that the water pressure difference between the two places is reduced). Therefore, as long as the water pressure difference between the two places is set in the valve driver 3 1 2 (from the water pressure difference between the inlet pressure monitor 8 2 and the outlet pressure monitor 83 as shown in FIG. 6 and FIG. 7 (Knowledge) is reduced to a reference value, for example at least about 5 ps i (when the water pressure difference between the two places is reduced to this reference value, it means that the filter 3 0 8 has been accumulated by the waste and the filter 3 0 8 needs to be washed away Waste particles may affect the normal operation of the waste filtering system), that is, the drain valve device 3 1 0 is opened (at this time, in the drain pipe of a wet scrubber or cooling water system, the The water flow in the Y-shaped filter device 300 and the return pipe is still flowing and circulating), then because the water pressure at the end of the filter housing 300 connected to the elongated conduit 3 0 4 is much higher than the valve seat connection 3 The water pressure at 〇9 is large (because the shape of the filter housing 3 02 is the cone described above). Therefore, according to the spraying principle, the water flow will be phased from the filter housing 3 002 to the elongated duct 304. The end of the connection is sprayed out of the nozzle of the valve seat takeover 309 The waste particles previously staying in the filter 308 can be collected as one nanometer as the flushing water flow is sprayed out of the valve seat to take over the nozzle 309 outside the tear filter 308. Inside a container (not shown). Among them, when the drain valve device 3 10 is opened to flush the filter 3 08, the water spray quantity Q3 sprayed from the valve seat to take over 309 is much less than the water quantity Q2 at the outlet of the extension duct 304. Therefore, the opening of the valve device 3 10 will not affect the system's positive operation status. Basically, the flushing water flow and waste particles continue to flow out of the cold valve device, until the waste particles in the sac

第13頁 552155 五、發明說明（11) 除去時，才關閉該排洩閥門裝置3 1 0。又，如圖六和圖七所示，可提供一電源供應器8 0和一控制面板8 1來連接至該排洩閥門裝置3 1 0、該入口壓力監測器8 2和該出口壓力監測器8 3，以便利在測出在該入口壓力監測器8 2的水壓大於該出口壓力監測器8 3的水壓達一預定值時，即可自動沖洗該濾器3 0 8。此外，上述排洩閥門裝置3 1 0之開啟，亦可利用可程式邏輯控制器（PLC)來控制，而利用PLC來控制的方式可分別三種： (1)以壓力差來控制該排洩閥門裝置3 1 0的開與關的作動， (2 )以運轉時間來控制該排洩閥門裝置3 1 0的開與關的作動， (3 )以壓力差和運轉時間來控制該排洩閥門裝置31 0的開與關的作動，當壓力差或運轉時間達到，則自動開啟或關閉該排洩閥門裝置3 1 0。再者，在該濾器3 0 8破損時，只須打開該頂蓋3 0 6即可取出破損的該濾器3 0 8，並將完好的新濾器，置入該濾器殼體3 0 2即可。是以，本發明所提出的可自動沖洗的y形過濾裝置Page 13 552155 V. Description of the invention (11) The drain valve device 3 1 0 is closed only when it is removed. Also, as shown in FIGS. 6 and 7, a power supply 80 and a control panel 81 can be provided to be connected to the drain valve device 3 1 0, the inlet pressure monitor 8 2 and the outlet pressure monitor 8 3. In order to facilitate measuring that the water pressure at the inlet pressure monitor 8 2 is greater than the water pressure at the outlet pressure monitor 8 3 to a predetermined value, the filter 3 0 8 can be automatically flushed. In addition, the opening of the above-mentioned drain valve device 3 1 0 can also be controlled by a programmable logic controller (PLC), and there are three ways to control the PLC: (1) the pressure valve is used to control the drain valve device 3 The opening and closing operation of 1 0, (2) the opening and closing operation of 3 10 is controlled by the operating time, (3) the opening and closing operation of 3 0 is controlled by the pressure difference and the operating time. With the closing action, when the pressure difference or the operating time is reached, the drain valve device 3 1 0 is automatically opened or closed. Furthermore, when the filter 3 0 8 is damaged, it is only necessary to open the top cover 3 0 6 to take out the broken 3 0 8 filter, and insert a new, intact filter into the filter housing 3 2 2 . Therefore, the y-shaped filter device capable of automatic washing provided by the present invention
