Supply Zhuzhou City cartridge filter dust collector pulse dust precipitator

Overview cartridge filter early on in Japan and Europe has in some countries in the 1970s, with 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 the food, welding and other industrial applications, so a lot of promotion over the years failed. In recent years, with new technology, new materials are constantly evolving, with Japan, the United States, the company is represented by the structure of the filter and the filter has been improved, so that the cartridge filter is widely used in cement, steel, power, food industry, metallurgy, chemical industry, the overall capacity increases several times, becoming the filtration area> 2000m2 large precipitator (GB6719-86 category), is to solve the conventional ultrafine filter dust collection difficult, high filtration velocity, cleaning poor , the best solution is easy to wear leaky bag, high operating costs, and available on a variety of bag market, compared to the electrostatic precipitator having an effective filter area, low pressure, low emissions, small size, long life and other characteristics of a new direction for the development of industrial dust. After the cartridge filter works dusty gas into the dust hopper, since sudden expansion of the air flow cross-section, part of a stream of coarse dust particles settling under gravity and inertia force down, fine grain size, density of dust particles into the After one filter chamber, by Brownian diffusion and sieving comprehensive effect, so that dust deposited on the filter surface, the purified gas is discharged into the clean air chamber from the exhaust pipe through the fan. When the cartridge-type dust collector filter resistance with increasing surface dust layer thickness increases, the resistance reaches a predetermined value, perform cleaning, then the pulse controller controls the opening and closing electromagnetic pulse valve. When the pulse valve is open, compressed air package through electromagnetic pulse valve injection tube through the hole on the spray a stream of high-speed, high-pressure ejector airflow, thereby forming an ejector airflow volume equivalent to 1 to 2 times defects induced flow together into the cartridge, so that a momentary positive pressure within the cartridge and produces bulging and fretting; dust deposited on the filter off, have fallen into the hopper, dust ash hopper through the discharge, continuous discharge. This pulse-jet cleaning method, is ranked by order of cleaning cartridge, pulse valve opening and closing time to generate a pulse action, the time required for the 0.1 ~ 0.2s; the interval between two adjacent pulse valve is opened and closed 1 ~ 2min, all the time to complete a cleaning cycle of the filter cartridge is required 10 ~ 30min. As the low pressure pulse cleaning device, so the device resistance according to the situation, deal with injection pressure, injection interval and injection cycle regulation. Features 1 cartridge, greatly increase the effective filtration area; 2, to ensure a low and stable pressure, increase the flow of air flow; 3, cartridge element compact, easy to install; 4, especially for large concentrations of dust filtration industry scope cartridge filter for tobacco, pharmaceutical, food, building materials, metallurgy, casting, chemical, power, power plant boilers, cement rotary kiln, steel blast furnace coke, machinery and other industries dust, material recovery and air filtration. Have qualified, effective, low-cost filter exhaust gas treatment equipment. First up in Dongguan Environmental Protection Technology Co., Ltd. specializes in electroplating factory industrial dust in the workshop, electroplating chemical odor smell gas treatment filter. Environmental technicians up to the factory, workshop examine the status quo on the ground, according to the production process of industrial processes, analysis of exhaust gas composition and gas production source, content and characteristics of various substances in the exhaust gas, it is determined the cause of the exhaust gas. Develop programs. Process according to property, plant size, how much gas content of the exhaust gas to formulate governance program.
