Description
本創作有關一種壓濾乾燥設備，尤指一種具有熱水與蒸汽熱能回收利用功能之壓濾乾燥設備。 The present invention relates to a filter-filter drying device, and more particularly to a filter-filter drying device having a function of recycling hot water and steam heat energy.
按，目前壓濾單元式污泥及其他各種濾料壓濾機，係在機台軌道上放置複數組可活動位移分開及重疊併靠之壓濾單元，各壓濾單元具有兩側濾室及相通污泥入口，在兩側濾室各覆置有濾布，並使兩側濾布經由污泥入口相連通。 According to the current filter unit sludge and other various filter presses, a plurality of filter units are arranged on the machine track to separate and overlap the movable displacement units, and each filter unit has two filter chambers and The filter inlet is connected to each other, and the filter cloth is placed on each of the filter chambers on both sides, and the filter cloths on both sides are connected through the sludge inlet.
實際進行壓濾污泥過程中，全部壓濾單元與濾布重疊併靠，則兩兩濾布外周閉合，同時利用泵浦將含水之污泥抽取送入壓濾單元之污泥入口及各濾布內，並且持續進行擠壓，使污水透過濾布及排污水孔流出，而污泥則被濾布包在濾室內，達到擠壓脫水目的。惟，此種單純擠壓脫水方式只能達到含水率60~86%之污泥乾燥度，無法更有效縮減污泥體積及佔地空間，並且後續搬運及再處理成本昂貴。 In the actual process of press-crushing sludge, all the filter press units overlap with the filter cloth, and the two filter cloths are closed at the periphery, and the sludge from the water is pumped into the sludge inlet of the filter press unit and each filter. The cloth is continuously squeezed to allow the sewage to pass through the filter cloth and the sewage drain hole, and the sludge is wrapped in the filter chamber by the filter cloth to achieve the purpose of extrusion and dewatering. However, this simple extrusion dewatering method can only achieve a sludge dryness with a water content of 60 to 86%, and it is not possible to more effectively reduce the sludge volume and the land occupation space, and the subsequent handling and reprocessing are expensive.
為改良上述單純擠壓脫水方式之缺失，現今已針對壓濾機之壓濾單元內部增設熱氣加熱結構，使污泥所含之水分氣化成水蒸汽，並且配合真空泵浦往外抽送排放，以提高污泥乾燥度。惟，此種壓濾機之壓濾單元加熱結構須使用大量的熱能，相對的增加了壓濾作業成本，而且真空泵浦只是將水蒸汽直接往外排放，以 致浪費熱能資源。因此要如何解決上述問題，即為此行業相關業者所亟欲研究之課題所在。 In order to improve the lack of the above-mentioned simple extrusion dewatering method, a hot gas heating structure has been added to the filter press unit of the filter press to vaporize the water contained in the sludge into water vapor, and the pump is pumped out with a vacuum pump to increase the pollution. Mud dryness. However, the filter press unit heating structure of the filter press must use a large amount of heat energy, which relatively increases the cost of the filter press operation, and the vacuum pump only discharges the water vapor directly to the outside. Waste of thermal energy resources. Therefore, how to solve the above problems is the subject of research that the relevant industry players are eager to study.

The heat exchanger is heated to recover the hot water, so that the hot water continuously indirectly heats the vacuum dewatered sludge inside the filter chamber into a sludge cake, and the hot water circulation and the steam heat energy are recovered and compressed, thereby effectively saving heat energy and facilitating operation control. , in line with environmental protection needs.

當壓濾機1持續擠壓污泥漿6排出大半的污水時，即可啟動 蒸汽壓縮機31，而蒸汽壓縮機31係經由濾布124、排污水孔126、抽氣管路18，以對於各壓濾單元12之濾室123內之污泥漿6進行抽氣，讓污泥漿6之水分在抽真空時，相對降低沸點且沸騰成為水蒸汽，同時利用蒸汽壓縮機31將水蒸汽壓縮為再壓縮蒸汽，然後再壓縮蒸汽通過出口管路32與熱交換器23，以間接加熱於熱水回收管路22之回收熱水，使熱水循環通過熱水加熱裝置2與壓濾單元12進行加熱，以持續間接加熱濾室123內部真空脫水污泥成為污泥餅61(參閱第三圖)，而達到熱水循環與蒸汽回收再壓縮使用，更有效節省熱能，並且方便操作控制，符合環保需求。最後壓濾機1打開活動座14，再朝右逐一夾拉打開各壓濾單元12及濾布124，使各壓濾單元12位移分開，以由各濾室123中卸落已脫水之污泥餅61。 When the filter press 1 continues to squeeze the sludge 6 to discharge most of the sewage, it can be started. The steam compressor 31, and the steam compressor 31 is pumped through the filter cloth 124, the sewage drain hole 126, and the suction line 18 to pump the sludge 6 in the filter chamber 123 of each filter press unit 12 to allow the sludge When the water of the slurry 6 is evacuated, the boiling point is relatively lowered and boiled into water vapor, while the steam compressor 31 is used to compress the water vapor into recompressed steam, and then the steam is compressed through the outlet line 32 and the heat exchanger 23 to indirectly The hot water is heated in the hot water recovery line 22, and the hot water is circulated through the hot water heating device 2 and the filter unit 12 to continuously indirectly heat the vacuum dewatered sludge inside the filter chamber 123 into a sludge cake 61 (see The third picture), to achieve hot water circulation and steam recovery and re-compression use, more effective in saving thermal energy, and convenient operation control, in line with environmental protection needs. Finally, the filter press 1 opens the movable seat 14, and then pulls the filter press unit 12 and the filter cloth 124 one by one to the right to displace the respective filter press units 12 to remove the dehydrated sludge from each filter chamber 123. Cake 61.
請參閱第七圖所示，當壓濾機1在打開各壓濾單元12以卸落污泥餅61(參閱第三圖)之前或之後時，熱水加熱裝置2與熱水泵浦26停止輸送熱水，而熱水回收管路22分接有氣壓控制管路4、壓縮空氣源41與控制閥42，利用氣壓受控推動熱水，使熱水經由壓濾單元12之熱水入口127與熱水循環管路27，而回流至熱水槽24內，以避免浪費各壓濾單元12內部熱水之熱量。 Referring to the seventh figure, when the filter press 1 is before or after opening each of the filter press units 12 to discharge the sludge cake 61 (see the third figure), the hot water heating device 2 and the hot water pump 26 are stopped. The hot water is conveyed, and the hot water recovery line 22 is connected to the air pressure control line 4, the compressed air source 41 and the control valve 42, and the hot water is controlled by the air pressure to make the hot water pass through the hot water inlet 127 of the filter unit 12. The hot water circulation line 27 is returned to the hot water tank 24 to avoid wasting heat of the hot water inside each of the filter press units 12.
請參閱第八圖所示，當壓濾機1在打開各壓濾單元12以卸落污泥餅61(參閱第三圖)之後，壓濾機1再次推動各壓濾單元12位移，使全部壓濾單元12與其濾布124重疊併靠，則兩兩相鄰濾布124外周閉合，然後清洗水槽5利用清洗水管路51與清洗水泵浦52輸送溫清洗水，將溫清洗水經由壓濾機1送入各壓濾單元12之排污水孔126內，以利用溫清洗水進行沖洗濾布124。 Referring to the eighth figure, after the filter press 1 opens the respective filter press units 12 to discharge the sludge cake 61 (refer to the third figure), the filter press 1 pushes the displacement of each of the filter press units 12 again to make all The filter unit 12 overlaps with the filter cloth 124, and the outer circumferences of the two adjacent filter cloths 124 are closed. Then, the cleaning water tank 5 uses the washing water line 51 and the washing water pump 52 to transport the warm washing water, and the warm washing water is passed through the pressure filter. The machine 1 is fed into the drain hole 126 of each filter unit 12 to rinse the filter cloth 124 with warm wash water.
