Before introduction of biomass boiler precipitator first explain what is biomass boiler, biomass boiler is a kind of boiler is used as boiler fuel to biomass energy is called biomass boilers, steam boilers into biomass, biomass hot water boilers, biomass stove, biomass thermal oil heaters, biomass boilers vertical, horizontal biomass boilers. Biomass boiler using the most suitable biomass fuel combustion reciprocating grate combustion equipment ----. Boiler in the structural design, compared to the traditional boiler furnace larger space, but arranged very reasonable secondary air is conducive to biomass fuel combustion moment when a lot of precipitation volatile combustion. Boilers can be equipped with fuel (gas) burner ignition achieve ignition automation. Boiler feed, combustion, slag, water supply, ignition can be automatically controlled, the operation is very convenient. The boiler is equipped with automatic cleaning device can promptly remove the fouling of boiler heating surface, to ensure efficient and stable operation of the boiler. Rear of the boiler economizer arranged, may also need to arrange air preheater according to the user. Compared with the traditional boiler, higher efficiency boilers, exhaust gas temperature is low. Efficient insulation, boilers, low surface temperature, heat loss is negligible. China strictly in accordance with national norms and standards, all of boiler pressure parts are made of high quality steel. Before each boiler factory to go through a rigorous inspection and testing, including pressure testing and X-ray detection. Someone set up the hole, check the door and watch the fire hole, etc., maintenance is very convenient. Biomass boiler most important feature: energy saving, environmental protection, and easy to install. Efficiency biomass boilers are generally above 80%, the boiler model large, burning more fully, the efficiency of the boiler will be higher. Highest reached 88.3%, 15% higher than the average level of efficiency of coal-fired boilers. Although the raw material is high efficiency boilers, but still will produce dust pollution on the environment. Therefore, the need to resolve the corresponding filter. Biomass boiler precipitator is made. Biomass boiler precipitator technology which deals with the production of each boiler flue gas generated in the process, are processed separately. Boiler flue gas generated. Dust by vacuuming pipe into the cyclone, this time in the big smoke particles under centrifugal force cyclone separation, large particles of dust from the cyclone discharge, small particles of dust entering the baghouse. After bag filter, pulse pipetting by adhering surface in the dust bag first concentrated in the precipitator ash bucket, using the following materials for recycling or use a controller. After processing by the baghouse net gas into the atmosphere through the fan from the chimney. After baghouse dust boiler flue gas treatment, can reduce dust pollution on the surrounding environment, to achieve the purpose of clean production. Biomass boiler precipitator design principles 1, dust removal equipment design and selection follow the "advanced technology, economical and practical" principle; 2, a reasonable selection of filter design, practical, reliable, advanced, with smooth running, low resistance, low power consumption , cleaning effect, and small size; 3, designed to achieve low investment, low operating costs. 2.3 design requirements 1, the selection of emission standards is "boiler air pollutant emission standards"〗 DB44 / 765-2010〗 The standard provides dust particles (other) emissions of its outer perimeter of the maximum allowable emission concentration of 30mg / m3. 2, the noise in line with "mechanical noise standard equipment" and "noise standard factory sector industrial enterprises." 3, dust trapping rate must reach 95% or more of three biomass boiler precipitator design 2.1, choose a dust way, cyclone cyclone structure simple and easy to manufacture, installation and maintenance management, investment in equipment and operating costs are is low, has been widely used for the separation of solid and liquid particles from a gas stream. In addition to Shen mechanism is to make the dust stream rotary motion by means of centrifugal force to separate and trap dust particles fall on the wall from the gas stream, and then with the force of gravity so that dust particles fall into the hopper. 2, baghouse with increasingly stringent emission standards, baghouse dust with its high efficiency, stable operation characteristics, at home and abroad has become the most common way of dust, its collection efficiency is generally greater than 99%, which can handle different particle size of dust. Baghouse different cleaning methods can be divided into mechanical vibrations, air cleaning and pulsed injection of three. Mechanical vibration cleaning commonly used in small amount of wind dust. Airflow blowback type cleaning effect of mechanical vibration better than the lower allowable filtration rate, and thus relatively large size of equipment, equipment pressure loss is large, a larger area. Pulse cleaning the strongest, the best, may allow a higher filtration rate, the smaller the pressure loss equipment, small footprint, low energy consumption. In summary, this design choice of pulse jet bag filter as a purification equipment. You can select a different filter based on different physical and chemical properties of dust, the design uses PPS peritoneal filter. Dust bag on the use of compressed air cleaning timing, reduced gathering dust, reducing resistance treatment process equipment design specifications dust bag: the set of dust removal process can be divided into two sets to deal with separately, were divided into 3T and 6T for processing. Soot (1) 3T boiler goes in first cyclone, for primary treatment, soot after re-entering the baghouse treatment, secondary treatment. Finally, from the chimney into the atmosphere through the fan. During the boiler must 6T dedusting system is turned off. Soot (2) 6T boiler goes in first cyclone, for primary treatment, soot after re-entering the baghouse treatment, secondary treatment. Finally, from the chimney into the atmosphere through the fan. During the boiler must 3T dedusting system is turned off. (3) fluctuations due to the boiler flue outlet, designed in the front of each cyclone inlet valve installed an electric mix, in order to avoid overheating due to dust inside the case lead to burn bag.
