Boiler exhaust gas treatment plan

Boiler exhaust gas treatment plan

Introduction to boiler exhaust gas treatment:

       Boilers, furnaces, and generator exhausts mainly contain pollutants such as SO2, NOX, soot, and Ringermann blackness. At present, the dust removal methods mainly include electric dust removal, bag type dust removal, and swirling plate wet type (maize) dust removal. Desulfurization methods mainly include: desulfurization in the furnace, dry desulfurization of flue gas, wet desulfurization of flue gas, and the like. The dry processing equipment is huge and the investment is large; the economical and practical angles are more commonly used in the wet packed absorption tower, the plate type absorption tower, the cyclone absorption tower, etc. At present, the treatment of such exhaust gas is usually carried out by an alkali absorption method or a double alkali method. It is a desulfurization method that is currently mature and approved by the Environmental Protection Agency

 

Boiler exhaust gas treatment performance and characteristics:

        1. Product features: washing working principle, high efficiency of dust removal and desulfurization, capturing more harmful gases. The JF flue gas purifier integrates desulfurization and dust removal into one. It is a spray method with unique nozzle design. Under a certain water supply pressure, the water mist of the dense layer is sprayed, and the dust and harmful gas are in full contact with the water mist, so dust removal, desulfurization and removal are carried out. The effect of nitrogen and washing carbon black is greatly improved compared to other wet dust collectors. The dust removal rate is ≥95%, the sulfur dioxide removal rate is ≥90%, and the flue gas Ringermann blackness is <1 level. The design of the dewatering plate is reasonable and unique, and the dewatering effect is good. The dewatering device is provided in the cylinder body, and the design of the dewatering plate is reasonable and unique. When the mist passes through the dewatering device, it is deflected by the collision and flows along the wall of the cylinder to prevent secondary water and high dehydration efficiency.

        2, low resistance, water saving, power saving, low operating costs. The flue gas is naturally introduced from the lower part of the cylinder. The cross section is large and the wind speed is small. Therefore, the smoke resistance is small, the main resistance is ≤900Pa, and the system resistance is ≤1200Pa. Because of the small resistance, the power consumption is also small. In addition, the discharged water passes through sedimentation and is closed and recycled. On the one hand, it saves water resources, on the other hand, it prevents sewage from flowing into the sewer, causing secondary pollution, achieving water-saving and power-saving effects, and reducing operating costs.

        3, the equipment operation is relatively simple and convenient, the maintenance is very small, easy to operate, manage, maintain, high operating rate, adapt to a variety of different working environments.

        4. The equipment has strong adaptability to the fluctuation of SO 2 concentration in flue gas. Different desulfurization processes can adapt to different sulfur content. Our company adopts double alkali method, which is the desulfurization method recognized by the mature and environmental protection bureau.
