The filter cover 50 is installed in the buffer area 42 so as to be sealed by each process, and each filter cover 50 has a process gas discharge pipe which flows through the inlet port 2 and discharges the process gas that has passed through the dust collecting filter 1. 72 and the backwashing gas inlet pipe 62 into which the backwashing pulse gas flows are respectively connected, and the solenoid valve 60 is mounted to the backwashing gas inlet pipe 62. Process gas discharge pipe 72 is composed of an outlet pipe 74 for discharging the process gas from the filter cover 50 and an inlet pipe 76 for introducing the process gas of the outlet pipe 74 into the buffer area 42, As the on / off valve 70 is mounted, a higher pressure backwash gas is always discharged through the filter by using a completely sealed backwash ejector. By preventing the reversal phenomenon, the backwashing efficiency of the filter is greatly improved, and the pressure applied to the entire surface of the filter can be maintained relatively uniformly and high when the backwashing gas is ...

Disposable air filter

A disposable air filter includes a pair of cover members (14, 16) which enclose an outlet body (18) defining an outlet chamber (20) communicating with an outlet tube (22). A pair of panel filter elements (30, 32) are supported on opposite sides of the outlet body (18). Fasteners (68) interconnect the cover members (14, 16) so that they compress seals (42, 44) carried by the filter elements (30, 32) against the outlet body.

Coagulating member of conical filter

Предложен пористый коагулирующий элемент 25 фильтра конической конфигурации, расположенный внутри цилиндрического корпуса 21 фильтра так, что площадь между элементом и стенкой увеличивается в направлении потока первичной фазы для поддержания круговой скорости постоянной или уменьшающейся в направлении потока первичной текучей среды. Элемент 25 можно изготовить с закругленными концами и скошенными стенками, оканчивающимися заостренной вершиной, однако более предпочтительно изготовить и закрепить его внутри корпуса 21 фильтра и применять плоские колпачки на его обоих концах. Элемент 25 фильтра можно изготовить под вакуумом или из среды в плоской листовой форме, которую можно сложить в виде складок, если это требуется.

Process and apparatus for purifying filter material of gas filter

本发明涉及气体过滤器滤料净化工艺：步骤一是通过关闭净化气体侧的单个或一排过滤节来阻止气流穿过滤网；步骤二是向已隔开过滤节供给缓慢气流，产生穿透滤网的反吹气体；步骤三是超短时地打开脉冲阀(如隔膜阀)产生压缩气体脉冲，使第二步净化过程中还没有从滤网上掉落的颗粒松脱；步骤四是停止反吹气体供应；本发明还涉及从过滤器滤料净化气体侧隔离一个或多个过滤节的装置：通过靠近过滤节的滑板(盖子、帽子)6，盖住喷嘴管7或与喷嘴管8相连，可以将单个过滤节4或者一排过滤节5从运行中的过滤器中隔离出来。与反吹或脉冲喷吹系统相比，过滤面积可以降低10%至25%，压缩气体压力和消耗可以降低20%至50%，或者过滤器压降可以减少高达50%；滤网的寿命可以增加至少200%；即使是变化的运行和烟尘状况，本技术也能够提供最高的运行保证，并且同时也是简单和低价的。
