[Desulfurization Dust Collector] Principle of Desulfurization Dust Collector How to Choose Desulfurization Dust Collector
Working Principle of Desulfurization Dust Collector
The desulfurization dust collector uses a certain concentration (Here we take 28% as an example span>)’s ammonia water is used as a desulfurizer, and the generated ammonia sulfate slurry is transported to the fertilizer plant treatment system. The required amount of ammonia used in the desulfurization process is automatically adjusted by the preset PH control valve and measured by the flow meter. The ammonium sulfate crystals are crystallized by the saturated ammonium sulfate slurry in the desulfurization dust collector, forming suspended particles with a weight ratio of about 35%. The slurry is pumped to the treatment site, undergoes primary and secondary dehydration, and then is sent to the fertilizer plant for further dehydration, drying, condensation and storage. While the flue gas is desulfurized through the boiler dust removal equipment, the boiler dust collector also generates considerable amounts of By-products can achieve certain economic benefits.
Characteristics of desulfurization dust collector
1. Washing-type working principle, high dust removal and desulfurization efficiency, and capture of more harmful gases.
2. The dewatering plate has a reasonable and unique design and good dehydration effect. There is a dehydration device inside the cylinder, and the design of the dehydration plate is reasonable and unique. When the mist passes through the dehydration device, it is intercepted and redirected by the collision, and flows down along the cylinder wall, preventing secondary water entrainment and high dehydration efficiency.
3, small resistance, water saving, electricity saving, and low operating cost.
4, small size, light weight, small footprint, easy installation and transportation.
5. The operation is relatively simple and convenient, with minimal maintenance. It is easy to operate, manage and maintain, has a high operating rate and is adaptable to various working environments.
6. It has strong adaptability to the concentration fluctuation of SO2 in the flue gas. Different desulfurization processes can adapt to different conditions. The sulfur content in coal;The desulfurization agent can be used in various forms such as lime, alkali, magnesium oxide, etc., all of which can achieve good desulfurization effects.
Classification advantages of desulfurization dust collectors
Desulfurization dust collectors are generally wet desulfurization dust collectors. Wet desulfurization and dust removal include water film desulfurization and dust removal, and impactWater bath desulfurization and dust removal, etc.
The advantage of the desulfurization dust collector is that it is easy to maintain, and can achieve the effects of dust removal and desulfurization (denitrification) at the same time by formulating different dust collectors; the disadvantage is that the dust removal liquid needs to be processed, which may cause secondary pollution.
After years of improvement, various types of water film desulfurization dust collectors have been developed into Venturi type, cyclone plate type, cyclone column type, float type, sieve plate type, etc., and the equipment technology is becoming more and more advanced. Mature, each has its own advantages and disadvantages. Enterprises can choose different types according to their own needs.
Applications in the coal-fired boiler desulfurization and dust removal industry
Desulfurization dust collector In the coal-fired boiler desulfurization and dust removal industry, dust removal and desulfurization equipment are widely used and can wet dust removal , Wet desulfurization can also be integrated with dust removal, desulfurization and dust removal. It is not only suitable for dust removal and desulfurization in coal-fired circulating vulcanized bed boilers in power stations, but also can be applied to wet desulfurization and dust removal and flue gas purification of coal-fired chain boilers. It has high sulfur dioxide removal efficiency and tail gas purification. Thoroughly, it is used in the furnace industry to remove hydrogen fluoride and kiln exhaust acidic exhaust gas purification equipment, etc., and to desulfurize pellet and sintering machine exhaust gases. The waste ammonia purification efficiency of the desulfurizer is extremely high. The original flue gas SO2 is removed from 11000mg/m3 to 120mg/m3 below, widely used in the field of steel plant pellet flue gas. It is a low-resistance and high-efficiency wet dust removal and desulfurization equipment and a novel environmentally friendly desulfurization equipment product. The desulfurization dust collector is a device used to remove harmful dust in the gas phase. On this basis, the desulfurization effect is increased, which is the desulfurization dust collector.

Desulfurization dust collector classification
Desulfurization dust collectors are usually divided into two categories: dry desulfurization dust collector; The dust collector uses a dry method to remove dust. Mainly uses the adsorption effect of activated carbon. Dry desulfurization dust collectors generally use multi-pipe dust collectors. The flue gas containing dust and sulfur compounds undergoes the dust removal part, and the dust-removed flue gas then undergoes the desulfurization part. Dry desulfurization dust collector is particularly suitable for handling flue gas with large air volume.
Wet desulfurization dust collector. When choosing a wet dust collector, you should consider that wet dust collectors all use water. If the size of the pollutant equipment is too small, harmful substances must be removed at the same time, or extremely fine carbon must be removed.To capture foam or dust, a wet desulfurization dust collector is often used. Keep in mind the issues of sewage treatment in wet desulfurization dust collectors to avoid secondary pollution.
When purchasing a desulfurization dust collector, you can choose based on the amount of gas the dust collector handles. The size of the dust collector is determined by the amount of gas the dust collector handles. For large displacements, you must choose a dust collector that can handle a larger volume of gas. It is not cost-effective if multiple small gas dust collectors are connected together. For small exhaust volumes, which type of desulfurization dust collector is more economical and practical should be compared, and the most efficient one should be selected to achieve environmental protection effects.
The desulfurization dust collector is selected according to the degree of dispersion of pollutant dust. Or if the particle size of the dust is less than a few microns, consider using an electrostatic precipitator in a wet desulfurization precipitator. Since the dispersion of dust varies with the environment or operation, it can be determined according to the environment and the performance of the dust collector.
When purchasing a desulfurization dust collector, you should focus on the selection of dust collector materials. The materials need to have very good wear resistance. If used for a long time, it is best to apply wear-resistant coating on the inner wall of the desulfurization dust collector or other parts that are prone to wear to increase the wear resistance and improve the working efficiency of the desulfurization dust collector. The friction of the desulfurization dust collector is reduced to avoid overheating of the desulfurization dust collector due to friction, and has a good effect in protecting the desulfurization dust collector.
