What are the common boiler dust collectors
1. Coal fired boiler dust collector
The dust removal efficiency reaches above 99.9, the dust emission is controlled below 30mg/Nm3, and it can handle high concentration dust below 100g/Nm3. Advanced sealing measures, air leakage coefficient less than 2%, advanced structural design, large filtering area per unit volume, and small equipment volume. The unique and effective cleaning method prolongs the lifespan of the filter bag. The unique and effective cleaning method prolongs the lifespan of the filter bag. The main components have reliable quality, long service life, and good performance. High stability, high degree of automation, and convenient daily maintenance. The operation status of coal-fired boiler dust collectors is easily affected by the operation status of the boiler and its ancillary equipment, and factors such as air leakage and pipeline blockage can affect the amount and variation of flue gas. Air preheater. Increase. Temperature, oxygen content, nitrogen oxide content, moisture content, dust content, smoke particle size, etc. are all affected to varying degrees, affecting the dust removal effect.
2. Biomass dust collector
The process of biomass boiler dust collector is to treat the flue gas generated during the production process of each boiler separately. Smoke from the boiler. Dust enters the cyclone dust collector through the dust removal pipe. At this time, large particles and dust in the flue gas are separated by the centrifugal force of the cyclone dust collector, and the large particle dust is discharged from the cyclone dust collector. Fine dust enters the bag filter. Increase. The dust attached to the surface of the bag is filtered by the bag and collected in the dust collector’s hopper by pulse blowing, and then recovered or used by the material dropping controller. The clean air treated by the bag filter is discharged into the atmosphere through the chimney by a blower. The dusty flue gas from the boiler is treated by a bag filter, which can reduce the pollution of the flue to the surrounding environment and achieve the goal of clean production. The characteristics of biomass boilers are reliability and practicality, with dust collectors having the highest operational reliability and significantly reduced maintenance work and costs, even when used for smoke purification and product recovery. Improve overall system economy.
3. Vertical boiler dust collector
The desulfurization and dust collector, biogas desulfurization tower, desulfurization spray tower, etc. can be assembled in sections, with the characteristics of small footprint and convenient transportation and installation. The vertical boiler dust collector adopts advanced composite materials and high-temperature resistant fiberglass resin in China, which enhances wear resistance and high temperature resistance, greatly extending its service life. The vertical boiler dust collector directly impacts the flue gas onto the water surface, saving water, reducing pollution, easy operation and maintenance, low operating costs, high dehydration effect, and is economical and practical. Type dust removal and desulfurization equipment. The vertical boiler desulfurization and dust collector (using spray type for biogas desulfurization tower and desulfurization spray tower) completely solves the practical problems of wet desulfurization and dust removal equipment. It is the most economical, practical, and ideal environmentally friendly product for coal-fired, oil fired boilers, coal water slurry boilers, kilns, metallurgy, chemical, acid mist purification, thermal power plants, cement plants, biogas desulfurization, and other industries.
4. Hand fired furnace dust collector
The dust removal efficiency of the hand burning furnace dust collector is high, reaching over 99.9%. There are few auxiliary equipment, low investment, low technical requirements, stable performance, strong adaptability to load fluctuations, easy operation and management, especially suitable for capturing fine and dry dust. The collected dry powder dust is easy to handle and recycle. This device is suitable for cleaning dust gases containing explosion hazards and sparks.
5. Chain furnace dust collector
Adopting offline dust cleaning technology to reduce dust cleaning pressure and compressed air consumption, and extend the lifespan of dust removal bags. Use common anti fiber filter media. Has excellent chemical properties and heat resistance. The long-term use temperature is 160 degrees. To prevent condensation, the entire dust collector is insulated. Especially the upper part of the upper box adopts special insulation technology. Protect cleaning equipment and electrical equipment Due to the double row structure, there are inclined partitions between the air inlet and outlet and the air duct. The ash hopper inlet is equipped with a spark arrester and a guide plate, and the load in each chamber is basically the same. It removes unburned hot dust particles and protects the filter bag. The intake manifold is equipped with a cold air valve, which is automatically controlled by dual detection points. When the temperature is too high, cold air is sucked in to prevent abnormally high temperature flue gas from directly entering the dust collector. All chain furnace dust collectors are automatically controlled by PLC, with machine side control and maintenance functions. The upper computer uses Kingview software to comprehensively display the operating status. Equipped with multiple alarm devices.
