What are the differences in dust collectors configured for boilers of different tonnages?
Firstly, it is important to calculate the weight of flue gas based on the coal consumption of the boiler, and then select different types of dust collectors; To solve the problem, let me introduce to you the dust collectors of various tonnages
1 ton boiler dust collector workflow:
The dusty gas first enters the Mars trap, undergoes primary dust removal by the Mars trap, and then passes through the bag filter. Under the guidance of the ash hopper guide system, the large particle dust is separated and directly falls into the ash hopper. The remaining dust enters the middle box filtration area with the airflow, and the filtered clean gas passes through the filter bag and is discharged through the upper box exhaust pipe. As the filtration progresses, when the dust accumulation on the surface of the filter bag reaches a certain level, it automatically falls into the ash hopper and is discharged through the ash discharge valve. After passing through the desulfurization tower for desulfurization.
2-ton boiler desulfurization and dust removal equipment atomization spray tower:
The distance between the spray components is determined based on the trajectory and residence time of the sprayed droplets, where they come into contact with the flue gas and SO2 is absorbed through the surface of the droplets. The arrangement of the air inlet is designed to maintain a downward sloping slope towards the absorption tower, thereby ensuring the residence time and uniform distribution of the flue gas.
The atomization spray tower consists of several parts, including flue gas, spray system, defogger, and flue gas outlet. The desulfurization absorption tower has the characteristics of pressure reduction, good gas-liquid distribution, wide adaptability to load changes, strong driving force for heat and mass transfer, and desulfurization; During the absorption process, the slurry from top to bottom undergoes complex physical and chemical reactions on its surface under the influence of high-temperature and high-speed flowing flue gas. On the one hand, the water on the surface of the slurry absorbs SO2 from the flue gas and undergoes a diffusion process from the outside to the inside of the slurry particles. Within the slurry particles, there is a concentration gradient of SO2; On the other hand, the water on the surface of the slurry gradually evaporates, and the surface water gradually decreases, spreading from the inside of the slurry to the surface. During the absorption evaporation process of slurry droplets, the surface moisture gradually decreases and the concentration of SO2 on the surface gradually increases. Therefore, as the droplets descend, the slurry droplets gradually saturate during the evaporation and absorption process, and the absorption process tends to stop. And during the descent process, the collision of droplets causes small droplets to become large droplets, reducing the surface area of the absorbent. The comprehensive result of these processes is that the absorption rate gradually slows down during the falling process of the droplet leaving the nozzle.
Advantages of a 3-ton boiler desulfurization and dust collector:
1. Low resistance, water-saving, energy-saving, and low operating costs.
2. The advantages of boiler desulfurization and dust collector are small size, light weight, small footprint, and easy installation and transportation.
3. The advantage of the 3-ton boiler desulfurization and dust collector is its washing type working principle, which can remove dust, desulfurization, and capture more gases.
4. Dehydration board, with good dehydration effect. The cylinder is equipped with a dehydration device and a dehydration plate. When the mist passes through the dehydration device, it is collided and diverted, flowing down along the cylinder wall to prevent secondary water carryover and dehydration.
5. The operation is relatively simple and convenient, with a large amount of maintenance required. It is easy to operate, manage, and maintain, with a high operating rate, and can adapt to various working environments.
6. The advantages of boiler desulfurization and dust collector are strong adaptability to the fluctuation of SO2 concentration in flue gas, and different desulfurization processes can adapt to different sulfur contents in coal; Various forms of desulfurizers such as lime, alkali, and magnesium oxide can be used, all of which can achieve good desulfurization effects.
Structural characteristics of bag filter for 60 ton heating boiler:
1. Advantages of filter cartridge dust collector: The filter material is wear-resistant, the structure is arranged with folded hard filter materials, there is no steel reinforcement skeleton, no filter material wear phenomenon, surface filtration replaces deep filtration of dust, and no longer penetrates into the interior of the filter material.
2. The original agitator for dust removal has been removed, and a YJD series automatic rotary ash discharge valve combination air shut-off device has been installed. Expanded the effectiveness of dust cleaning, reduced maintenance, tightly sealed and quickly discharged dust.
3. Due to structural improvements, the tightness of the equipment has been enhanced, and the air leakage rate can be less than 10%, further improving product quality.
4. The cover removal device and filter bag fixing method have been reformed, providing labor conditions for equipment maintenance and upkeep.
5. The pressure of compressed air used for dust cleaning has been reduced from the original 5-7 kg/cm2 to the current 3 kg/cm2. Small electric furnace dust collectors can achieve a dust cleaning effect of 5-7 kg/cm2, which expands the scope of use of heating boiler dust collectors.
6. The spraying device has added a protective cover, and the cover structure adopts rainproof measures, so that the dust collector can be placed outdoors without the need for an additional rain shelter, reducing construction investment.
The above content includes but is not limited to the various tonnage advantages of boiler dust collectors. Our company can also customize according to local acceptance standards and equipment usage, taking into account industrial and mining considerations.
