10t/h Coal-fired Boiler Cloth Bag Dust Removal and Desulphurization Equipment

　　Structure Principle of Boiler Dust Collector

　　The structure of boiler dust coflector is dust collector box, cloth bag, framework, pulse valve, cylinder, PLC control cabinet, cinder valve, injection combination and so on. Now let’s talk about it in detail.

　　First. Box body of boiler dust collector: All welding of boiler dust collector is completed on workshop platform, which can not only ensure the leveling of dust collector drawing board, simplify the overall installation of dust collector, but also guarantee the installation quality. The boiler dust collector adopts the structure mode of large roof and double sealing canopy, which is convenient to repair the dust collector and effectively reduces the labor intensity of the workers.

　　Second, Cloth bag of boiler dust collector: this dust collector cloth bag adopts a kind of filter material made of PTFE titter material (polytetrafluoroethylene fiber) by three—dimensional needling. PTFE fiber is in macromolecular linear structure, so it has strong temperature resistance, wear resistance, corrosion resistance and chemical resistance stability, and is widely used in all kinds of bad flue gas filtration environment, such as iron and steel, electric power, waste incineration and so on.

　　Third, Framework of boiler dust collector Dust removal framework adopts bag cage with conical mouth structure, which is self—parallel under the action of gravity. The distance between the filter bag and the filter bag is uniform, and the air flow In the whole bag room is more uniform. The manufacturing and welding of filter bag cage framework conform to the corresponding industry standards.

　　Fourth, Electromagnetic pulse valve of boiler dust collector : Electromagnetic pulse valve is the power element of fitter bag ash cleaning, and its selection is related to the cost of dust collector and ash removal effect, The diaphragm of the pulse valve is durable and has a life of more than 1 million times, which meets the high efficiency operation requirements of the pulse electromagnetic valve and greatly reduces the maintenance workload.

　　Fifth, Cylinder of boiler dust collector : The actual production condition of boiler dust removal is very complex, and sometimes there will be a brief state of power outage and gas outage. For the safe operation of bcxler and fan and other equipment. Jinzhu environmental protection coordinated cylinder manufacturers has jo4ntly developed a joint protection device of self—locking cylinder drive mechanism and safety gas storage tank, The self—locking cylinder drive mechanism ensures that there is no signal control of the control system in me case of power outage, and the mechanism will remain in its original state and will not misoperate.

　　Sixth, PLC control cabinet of boiler dust collector Boiler cloth bag dust collector is set up with PLC control cabinet, which can monitor the operating conditions of the system in real time by touching the display screen. The control cabinet has an output interlace, which is convenient for remote monitoring.

　　Seventh, Cinder valve of boiler dust collector: The material temperature of ash discharge can reach 280 CC, and the bearing at both ends can be isolated from the impeller, which can prevent the contact between ultra—fine powder and bearing. The temperature of conveying materials by high temperature resistant unloader can reach 500CC. which is connected by sprocket wheel. There is a certain distance between the reducer and the unloader shell. The automatic ash discharge of materials is guaranteed.

　　Sixth, Injection combination of boiler dust collector : The ash cleaning mode of boiler dust collector is fixed injection, and each filter room is equipped with 1 - 2 pieces of air bags. The pulse valve on the air bag is connected with the injection tube, and a injection tube clears ash for a row of filter bags. According to the properties of black liquor smoke from papermaking, stainless steel injection tube is used to improve the service life of the equipment.

　　Notes in installation and use of centrifugal force dust collector

　　Installing dust collector needs to ensure sealing, and apply soap liquid to check after installation.

　　It should be repaired regularly in use to ensure efficiency, and the wear pattern of wear—resistant coating should be checked after operation for 3—5 years.

　　Attention should be paid to the sealing of ash discharge port (air lock) in operation.

　　The selection of dust collector should be considered in accordance with the smoke discharge volume of boiler, and the fan can overcome the smoke exhaust resistance.
