Pulse cartridge filter with cartridge filter element as composition or use of pulse jet dust collector. Cartridge filter press installation points, can be divided into the permafrost, side-mounted, ceiling-mounted, coat type. Divided by cartridge filter cartridge materials can be divided into long fiber polyester cartridge filter, cartridge filter composite fiber, anti-static cartridge filter, cartridge filter retardant, film cartridge filter, Nano-cartridge dust collector and so on. Early pulse cartridge filter has been in Japan and Europe in some countries in the 1970s, with a small size, high efficiency, low investment, easy maintenance, etc., but because of equipment capacity is small, difficult to be combined into a wind capacity equipment, filtration velocity is low, narrow range of applications, only food, welding and other industrial applications, so a lot of promotion for many years failed. In recent years, with new technology, new materials constantly evolving, with Japan, the US companies on behalf of the filter and the filter structure has been improved, a traditional cartridge filter cleaning device has two cleaning ways, one is high-pressure air cleaning, a pulsed flow injection, practice shows that the advantage of the former is the airflow evenly, the drawback is the large gas consumption; the latter has the advantage of low air consumption, the disadvantage is weak airflow. This could be for two improvements: on the one hand, the increase in pulse jet pipe deflector strengthen induced airflow, on the other hand the cartridge upper duct diversion canceled the pulse induced airflow and airflow while fully into the cartridge . After this improvement less air consumption, air evenly, good cleaning effect, according to the calculations, cleaning air flow technology improved pulse 3-5 times the volume. 2 gas flow distribution plate cartridge filter distribution is very important, we must consider how to avoid due to the higher wind speeds result in high wear areas device filter inlet. Air distribution plate for cartridge filter has unique requirements, air distribution must be very stable and uniform. Can help decrease the airflow and dust rising, the air distribution plate opening rate of 35%. According to calculations, the drag coefficient <2, we can see in the air speed <0.8m / s case, porous air distribution plate to meet the requirements of cartridge filter. These improvements allow the cartridge filter is widely used in the cement industry, steel, electricity, food, metallurgy, chemical industry, etc., to increase the overall capacity several times, becoming the filter area> 2000m2 large dust (GB6719-86 class), is to solve the traditional ultrafine filter dust collection difficult, filtration velocity is high, the cleaning effect is poor, the best solution is easy to wear leaky bag, high operating costs, and various existing bag on the market, compared with the effective electrostatic precipitators filter area, low pressure, low emissions, small size, long life and other characteristics of a new direction for the development of industrial dust.
