FRP desulfurization dust collector
Working principle
This product adopts the principles of inertial collision, condensation, centrifugal force, etc. Under the power of the induced draft fan, the flue gas falls from a certain height and impacts the liquid surface at high speed, forming water mist. Most of the particles sink into the water. Under the action of the dust collector's diverter, the atomized airflow rises rapidly. The droplets further collide and condense to form a water-cement mixture. The water-cement mixture passes through the cyclone impeller to separate steam and water, thereby fully achieving desulfurization, dust removal and dehydration. Effect. This product also has a unique adjustable hood, which can be adjusted arbitrarily on the upper part of the equipment to adapt to various air volumes, thereby controlling the flue gas flow rate to ensure its normal operation. No matter how big the induced draft fan is, it will not carry water or cause corrosion. Its supporting facilities not only reduce losses, but also reduce maintenance and repair costs.
FRP boiler flue gas desulfurization and dust collector
Fuel combustion equipment is mainly industrial boilers. Industrial boilers are large in size and cover a large area, and consume a lot of coal. The pollution caused by the smoke and dust after combustion is discharged into the atmosphere is very serious. The harmful sulfur dioxide gas produced after fuel combustion is discharged into the atmosphere and combines with oxygen in the air to oxidize into sulfur trioxide, which then vaporizes with water vapor in the air to form smoke or combines with flue gas to form sulfides. These substances are twice heavier than air and often float in the lower atmosphere, causing air pollution. It causes harm to human health, reduces crop yields in large areas, and reduces the quality of industrial products.
Our country has always attached great importance to environmental protection and has made specific regulations on smoke and dust control and emission standards for working boilers. In recent years, there has been some progress in the recovery of tiny dust particles in flue gas. However, it has little effect on flue gas desulfurization. At present, the dust collectors produced by various manufacturers can only remove dust, but cannot eliminate sulfide in the flue gas. Based on the cooperation with universities and scientific research departments, and after several years of efforts and research and development, our company has produced a series of flue gas desulfurization dust collectors that integrate dust removal and desulfurization.
The series of FRP flue gas desulfurization dust collector is a wet dust removal and desulfurization device. It is a flue gas purification equipment designed and manufactured specifically to meet the requirements for smoke and dust emission concentrations reaching the first-class regional (less than /) standard in the national boiler air pollutant standards. It adopts today's advanced spray and ebullating bed optimal complementary combination technology to realize the joint action of multiple desulfurization and dust removal mechanisms, forming a stable and fast-moving water film inside the desulfurization dust collector, and the gas flow fully interferes with the bubbles and air flow. Aqueous mixture suspended layer. Its desulfurization and dust removal is different from the desulfurization and dust removal of cyclone water membrane and water filtration. It is a high-efficiency desulfurization and dust removal device.
Its main features are as follows
This desulfurization dust collector is suitable for smoke and dust removal and desulfurization of steam or hot water boilers, and the effects meet the national atmospheric emission standards.
This product has a tight structure, good sealing performance and corrosion resistance, low cost and long service life.
The equipment is small in size and light in weight. It is easy to install and move, making it easy to achieve multi-stage dust removal.
, using advanced spray water film technology to improve spray efficiency and save circulating water consumption.
It has strong adaptability to the total amount of flue gas and the concentration and fluctuation in the flue gas, and can adapt to % of the sulfur content in coal.
. This product is a wet type, with water and air fully exchanged. Tiny dust particles are adsorbed by water mist, and the discharged water is recycled through sedimentation and closed circulation. On the one hand, it saves water resources, and on the other hand, it prevents water from flowing into the sewer and causing secondary pollution. Add lime aqueous solution to the water to obtain a satisfactory desulfurization effect.
It has advanced dust removal performance and solves the shortcomings of various dust collectors that work on the cyclone principle due to reduced dust removal efficiency caused by boiler load reduction. Use lime to desulfurize, which is rich in sources. If digested ash (powder) is used, it can be added directly to the sedimentation tank. The water containing the lime solution is recycled and the cost is low.
