Boiler precipitator boiler precipitator is designed for use with coal-fired boiler flue gas dust removal equipment, coal-fired boiler flue gas for the characteristics: high temperature, flue gas moisture capacity, the flue gas contains large amounts of sulfur component, with strong corrosion and other characteristics, I developed a boiler precipitator selected material PPS + PTFE membrane filter media, to ensure that the dust emission concentration reached the following national requirements. System Equipment Performance: boiler bag filter due to the smooth running, low resistance, low power, cleaning effect, small footprint type LCM long bag offline pulse cleaning bag filter body protection systems, compressed air systems ( including tank, oil-water separators, piping), the control system (including instrumentation, PLC cabinets, MCC cabinet, field operations cabinet) and other components. Structural frame and cabinet - structural framework for supporting the filter body, hopper and ash equipment; box including the box, in the box and hopper, etc. bag, cage bone and flower plate - bag and cage bone ash formed a dust filter systems; flowers board for supporting the bag assembly and separate the filter chamber (dust above) and) net gas chamber, and as a maintenance platform dust bag assembly; bag components from the flower board loaded. Works boiler precipitator purification outer filter type, dust and gas from the draft tube into the filter chamber and each unit in the hopper by setting the smoke deflector; the design of the bag away from the inlet catchy vertical distance There are enough reasonable net airflow diversion and appropriate distribution of natural flow, reaching the entire filter indoor air distribution, dust and gas particles in the dust hopper directly after falling as natural sedimentation separation, the remaining dust boot diversion system next, with the airflow into the cabinet, clean filtered air through the filter bag through the box, the exhaust pipe emissions. Bag using compressed air injection cleaning, cleaning agencies by the air bag, the injection tube and electromagnetic pulse control valves' filter chamber outlet each row at the top of the bag is equipped with a blow tube, is on the lower side of the injection tube bag center with a blow ports on each injection tube has a pulse valve and the compressed air bag connected. When cleaning, the solenoid valve opening pulse valve, compressed air through the nozzle sprayed into the bag, with the surrounding gas ejector incident together inside the bag, causing the bag to form a comprehensive shake purge gas flow from the inside out, remove attached to the outer surface of the bag of dust, to achieve the purpose of cleaning. With the filter conditions will be, when the dust bag surface reaches a certain amount, the dust control device (differential pressure or timer, manual control) according to the set procedures to open the electromagnetic pulse valve injection compressed gas in a very short time Each pulse sequence through the nozzle valve through the injection tube several times on the induction of air injection gas into the bag, the air waves are formed, so that the bag mouth by a sharp catch to shock and vibration bottom expansion and cattle production, resulting in a strong clear ash effect, shake off the dust on the filter bag. Cast furnace oil boilers point, "four" burst and smoke temperature anomalies startup bypass protection systems. The dust falls into the hopper through the cinder valve after discharge, the use of centralized sent ash facilities. Boiler precipitator with online and offline two state cleaning function and offline maintenance functions. Boiler precipitator provided with a bag filter bag leak detection device for detecting condition and set the temperature, humidity, differential pressure and other online monitoring devices. Boiler precipitator control (including dust control, etc.) using PLc control. Dust control system of the entire implementation of automated unmanned straight defensive control, and feedback systems to large plant, the plant accepts large system remote control. All repair and maintenance work on the outer filter net gas chamber and machine execution without entering the dust inside. Protection technology boiler baghouse dust protection covers the body resistance and dust control bag to protect the core components. I designed the boiler bag filter around the object using a range of protection operation: 1) dust resistance control 2) Pre-spray device (pipe spraying device) 3) measures to prevent the paste bag 4) Bypass System
