ManufacturerdemisterIt is mainly composed of fixed devices such as waveform blades, plates, and clamps. In wet desulfurization, the absorption tower is prone to generate "fog" with a particle size of 10-60 microns during operation. "Fog" not only contains water, but also dissolves sulfuric acid, sulfate, sulfur dioxide, etc., which also causes contamination and severe corrosion of fans, heat exchangers, and flues. Therefore, the wet desulfurization process requires defogging of the absorption equipment, and the purified gas must be defogged before leaving the absorption tower.

The defogger nozzle is one of the main components of the defogging system, and the defogger nozzle mainly usesMade of plastic,Long service life. Application: The demister is used to separate liquid droplets carried by gas in the tower, ensuring mass transfer efficiency and reducing valuable material lossThe operation of the compressor behind the tower is usually carried out by installing a defogger at the top of the tower. It can effectively remove fog droplets of 3-5um. If a defogger is installed between the trays, it can not only ensure the mass transfer efficiency of the trays, but also reduce the spacing between the plates. So the defogger is mainly used for gas-liquid separation. It can also be used as an air filter for gas separation. In addition, wire mesh can also serve as a buffer for various instruments in the instrument industry, such as electronic shields to prevent radio wave interference. Wet desulfurization also contains dissolved sulfuric acid, sulfates, sulfur dioxide, and other substances.

If not properly resolved, any "fog" entering the chimney, the demister system consists of the demister body and the flushing system. Specifically, it consists of the secondary defogger body, flushing water pipeline, nozzle, support frame, support beam, and related connections, fixing, sealing components, etc. In fact, it is the emission of sulfur dioxide into the atmosphere, which also causes contamination and severe corrosion of fans, heat exchangers, and flues. Therefore, the wet desulfurization process requires defogging of the absorption equipment, and the purified gas must be defogged before leaving the absorption tower. The defogger is a key equipment in the FGD system, and its performance directly affects whether the wet FGD system can operate continuously and reliably.Mist remover manufacturerMalfunctions can not only cause the shutdown of the desulfurization system, but may even lead to the shutdown of the entire unit (system).

Layout form of defoggerCommon types include flat layout and roof layout. The structural defogger is mainly composed of plates and supporting devices. Plates are usually made of two major types of materials: polymer materials (such as polypropylene PP, FRP, etc.) or stainless steel (such as 316L, 317L, etc.). Generally divided into streamlined and folded types.

Performance guarantee (defogger nozzle)

(1) Mist removal efficiency: Under normal operating conditions, the concentration of fog droplets in the flue gas at the outlet of the defogger is less than 75mg/Nm3;

(2) Pressure drop: Without considering the interference before and after the defogger, ensure thatUnder flue gas load, the pressure drop of the entire defogger system is less than 120Pa.

(3) High temperature resistance: 80-95 ℃.

(4) Pressure resistance: Ensure that the blades can work normally when subjected to a flushing water pressure of 0.3MPa.

(5) Rinse nozzle: Full cone nozzle, with a rinse water spray angle of 90-120 degrees, spraying solid cones to ensure that all blades are covered. (All designs areThe water consumption under gas load, considering the requirement of system water balance, can be reduced by half by increasing the flushing interval time if the gas load decreases.
