Aforesaid this in the flue gas conditioning equipment of wet cottrell entrance, the compressed air line between the first manual ball valve and the first teletransmission pressure transmitter is provided with relief valve.By the pressure that relief valve can regulate compressed air hose to export.
Aforesaid this in the flue gas conditioning equipment of wet cottrell entrance, the junction of compressed air line and connecting line is provided with non-return valve.Non-return valve the water of available protecting water pipe can enter compressed air line thus pours in down a chimney and enter drying machine.
Aforesaid this in the flue gas conditioning equipment of wet cottrell entrance, the compressed air line between described drying machine and the first manual ball valve is provided with hydrophobic valve.Hydrophobic valve is used for possible ponding in the unrestrained compressed air line of timing, prevents winter compressed air line from freezing.
Aforesaid this in the flue gas conditioning equipment of wet cottrell entrance, water pipe is provided with orifice flowmeter.Passing hole flowmeter can control pipe outlet flow and pressure.
Aforesaid this in the flue gas conditioning equipment of wet cottrell entrance, the material of air pipe line and water pipe is SS2205.SS2205 is two phase stainless steel, adopts this material can reach anticorrosion demand.
Aforesaid this in the flue gas conditioning equipment of wet cottrell entrance, the atomizing particle size < of nozzle 30 μm; The spray angle of nozzle 60 ° ~ 90 °.
Compared with prior art, the utility model is by increasing air treatment system and water treatment system at wet cottrell entrance, by the high-speed jet of air, mechanical atomization is carried out to low-temperature cooling water, cooling water after atomization considerably increases area coverage in flue, coverage rate about 150% ~ 200%.Saturated wet flue gas in absorption tower meets with the cooling water after low-temperature atomizing, and fully mix with it and heat-shift, cigarette temperature drop is low about about 1 DEG C.Along with the reduction of cigarette temperature, water vapor condensation in flue gas, in the condensation process of steam, there is coalescence effect in the particulate (SO3, ammonium salt, fine solid particle etc.) in flue gas simultaneously, bulky grain is condensed into by granule, be conducive to the seizure of wet scrubber, improve wet dust removal efficiency.
