Description

膨脹膜片壓榨污泥或漿料之濾板Expansion membrane pressing sludge or slurry filter plate

本創作係有關一種膨脹膜片壓榨污泥或漿料之濾板,尤指一種可運用於壓濾機上之濾板,並以複數濾板疊合併靠,可對污泥或漿料進行過濾脫水,且注入加壓流體產生膜片膨脹效應,對污泥或漿料進行再次壓榨脫水之濾板。The present invention relates to a filter plate for inflating a diaphragm press sludge or slurry, especially a filter plate which can be applied to a filter press, and stacked with a plurality of filter plates to filter sludge or slurry. Dewatering, and injecting a pressurized fluid to produce a diaphragm expansion effect, and the sludge or slurry is subjected to a re-pressing dewatering filter plate.

按,污泥為事業廢棄物或漿料為事業產品,污泥廢棄或漿料產品利用皆需符合法律或公司生產規範,尤其污泥透過過濾脫水成較便於運送及處理的泥餅,基本上脫水設備的種類可分成圓胴真空過濾機、皮帶式、離心式脫水機及板式壓濾機,尤其板式壓濾機脫水的泥餅含水率較低、污泥脫水操作容易、脫水時不會產生惡臭及降低運送及終端掩埋、固化處理成本。According to the sludge, the business waste or slurry is a business product. The sludge disposal or slurry product utilization must comply with the law or the company's production specifications. In particular, the sludge is dewatered by filtration into a mud cake that is easier to transport and handle. The type of dewatering equipment can be divided into a round vacuum filter, a belt type, a centrifugal type dewatering machine and a plate type filter press. In particular, the plate cake press dewatering mud cake has a low moisture content, the sludge dewatering operation is easy, and the dewatering does not occur. Stench and reduce the cost of transportation and terminal burying and curing.

次按,板式壓濾機主要技術特徵在於複數個濾板重疊併靠,經由污泥或漿料持續地進料加壓至濾板濾室,且濾板側邊設有濾液出入口,當外部加壓流體供應至濾板加壓接口,則濾板兩側膜片產生膨脹再次壓榨污泥或漿料成為泥餅或事業產品,達到固液分離的效果。Sub-press, the main technical feature of the plate filter press is that a plurality of filter plates overlap and lean, and the feed is continuously fed to the filter plate filter chamber through sludge or slurry, and the filter plate is provided with a filtrate inlet and outlet on the side, when externally added When the pressure fluid is supplied to the pressure plate of the filter plate, the diaphragm on both sides of the filter plate is expanded to press the sludge or slurry to become a mud cake or a business product, thereby achieving the effect of solid-liquid separation.

惟查,濾板兩側因壓榨泥餅需快速供給及排放加壓流體,在壓榨過程中的流體必然需較快流速,但流體易受彈性膜片黏附芯板入口限制,導致二次加壓流體進流速度緩慢,將造成濾板兩側的膜片膨脹再次壓榨污泥或漿料無法在快速時間內達到所需之加壓流體供應及釋放壓榨壓力之問題點,難以有效快速降低泥餅或事業產品含水率。是以,習用膜片膨脹壓榨污泥之濾板,使仍有其未能快速完成再次加壓及釋壓行為,尚有改進空間。However, it is necessary to quickly supply and discharge pressurized fluid on both sides of the filter plate. The fluid in the press process must have a relatively fast flow rate, but the fluid is easily restricted by the elastic membrane adhesion core inlet, resulting in secondary pressurization. The slow fluid inflow rate will cause the diaphragm on both sides of the filter plate to expand and press the sludge again. The slurry cannot reach the required pressure fluid supply and release the pressing pressure in a fast time. It is difficult to effectively reduce the mud cake quickly and effectively. Or the moisture content of the business product. Therefore, the filter plate for the expansion of the compressed sludge is conventionally used, so that there is still room for improvement because it fails to quickly complete the re-pressurization and pressure release behavior.
