The XNT-type wet desulfurization and dust removal unit is an integrated system that combines dust removal and desulfurization, self-discharging or mechanical ash removal, and automatic water replenishment. This dust collector features a rational structure, simple operation, high dust removal efficiency, and long service life, making it suitable for the purification and desulfurization of flue gas from smaller capacity boilers and has been well-received by a wide range of users.
The XNT type wet desulfurization and dust removal unit is a cost-effective, easy-to-maintain dust removal equipment for wet scrubbing dust collectors. This type has been in operation for fifteen years, fully demonstrating its stable and reliable performance. It can be constructed using bricks or concrete, making it suitable for烟气 purification and desulfurization of smaller capacity boilers.
The XNT type wet desulfurization deduster utilizes TO resin from the Chinese Academy of Sciences' research achievements for corrosion and wear resistance treatment. The shell is constructed with metal or ceramic panels and a metal-ceramic hybrid structure, ensuring a long service life. Technically and economically, it can rival the granite deduster. It is an ideal technical equipment for desulfurization in various industrial applications, power plant boilers, particularly for coal powder and fluidized bed boilers.
The XNT type wet desulfurization and dust removal equipment is a desulfurization device with high efficiency, low pressure loss, and dust removal capabilities. It is mainly composed of a cylinder, a spray device, a sieve plate, a dewatering and demisting unit, overflow holes, and cleaning holes. Its working principle is as follows: flue gas containing smoke, dust, and sulfur oxides enters the cylinder through the inlet flue. Alkaline absorbent solution containing [OH-] ions is sprayed out from the upper, middle, and lower parts of the filter bubble desulfurization and dust removal equipment through spiral nozzles, forming multiple rows of high-speed atomized water curtains in the opposite direction to the flue gas. This increases the collision probability between the smoke, dust, and sulfur oxides with water, and takes full advantage of the speed of the atomized droplets to create a high relative gas-liquid velocity, thereby enhancing the dust removal and desulfurization effects of the equipment.
The XNT type wet desulfurization and dust removal unit utilizes TO resin from the Chinese Academy of Sciences for corrosion and wear resistance treatment. The shell is constructed with metal or ceramic panels and a metal-ceramic hybrid structure to ensure long service life, comparable in both technology and economy to granite dust removal units. It is an ideal technical equipment for desulfurization in various industrial applications, power plant boilers, especially for coal powder and fluidized bed boilers, with particle size less than 0.5uM.
Advantages of the XNT type wet flue gas desulfurization and dust removal device:
1. Corrosion-resistant, long service life
Internal anti-corrosion is achieved through the use of acid and abrasion-resistant mortar lining technology, offering strong chemical and thermal stability, as well as a long service life.
If a metallic dust collector is used, the entire dust collector will be corroded away within 3 months.
If a dust collector is made of glass fiber material, the entire unit will be corroded within 2 months.
High dust removal efficiency
A wet flue gas desulfurization and dust removal unit is preceded by a bag dust collector for secondary dust removal, thereby achieving an efficiency of up to 99.5%. The fine separation particle size can reach 2um, and the exhaust air meets environmental protection standards (the company's environmental protection department's inspection report installed for the customer is below).
High desulfurization efficiency
Pure water has slightly lower dust removal efficiency, so Huakang Company has made improvements. It mainly involves water washing, followed by alkali neutralization, using lime water and slag wastewater, which yields good results with an efficiency of around 90%.
4. Suitable for various smoke volumes and sulfur dioxide concentrations
For varying smoke volumes and sulfur dioxide concentrations, this wet flue gas desulfurization and dust removal unit can achieve a high desulfurization rate.
5. Mainly handles various exhaust gases
Primarily deals with exhaust gases; acid mists formed by sulfuric acid, nitric acid, hydrochloric acid, inorganic acids, formic acid, acetic acid, propionic acid, and organic acids. Such as: H2SO4, hydrogen chloride (HCl) gas, hydrogen fluoride (HF) gas, chromic acid mist (CrO3), hydrogen cyanide gas (HCN), hydrogen sulfide (H2S), and so on.
6. Zero Sludge Emission
Desulfurization and dust removal sludge can be recycled as fly ash, eliminating the issue of secondary pollution caused by discharging onto the ground, without the need for sludge discharge equipment.
7. Zero Wastewater Emission
All processes utilize recirculated water; no water is discharged or wasted into the kiln.
8. Low power consumption
Low equipment operation cost, power consumption 9KW
9. The wet desulfurization deduster features a three-stage dewatering unit, achieving clean gas and water separation, and the fan is water-free.
10. Easy installation, short construction period for the entire equipment
