Description

The Wet-type high-efficient smoke eliminator

The utility model relates to smoke eliminator, is specially the Wet-type high-efficient smoke eliminator.

Wet dust removal is the present industrial dedusting technology that is widely used, existing this type of device mainly contains various ways such as whirlwind water film type, hollow spray are tower, padding washing device formula, foam type, impact type, high energy Wen tubular type, or adopts the combination of above-mentioned several forms.Existing dust arrester is subjected to the limitation of its structure, often action intensity a little less than, to small dust can not capture effectively, the clearance of oxysulfide is also generally on the low side, and have that jet pipe, screen cloth and orifice plate easily stop up, power consumption height, water consumption are big, waste residue, wastewater treatment difficulty, maintenance management complexity, investment, the more high deficiency of operating cost.

The purpose of this utility model is for overcoming above-mentioned defective, but provide a kind of simple in structure, energy consumption is low, small investment, reliable high-effective dust-removing, the wet type smoke eliminator of desulfurization.

The utility model is to adopt following measure to realize: this Wet-type high-efficient smoke eliminator comprise and mix expansion chamber, have flue gas into and out of the high potential vortex separation chamber of slit, remove moist chamber, purified gas outlet, have reverse taper sediment case, the water level control apparatus of residual cake valve, smoke inlet at expansion chamber is provided with jet back mixing air intake duct, this jet back mixing air intake duct is made up of trunnion, air intake duct slit and anti-wet chamber, the top of high potential vortex separation chamber is an arch, removes moist chamber and is made up of one-level volute chamber and secondary volute chamber.

The utility model is provided with jet back mixing air intake duct and is furnished with high potential vortex separation chamber at the mixing expansion chamber, this structure can effectively utilize heat energy, kinetic energy and the potential energy of flue gas itself, increased the probability and the action intensity of the collision between the gas, liquid, solid material, diffusion, coalescence in the fluid greatly, have dedusting efficiently, desulfurized effect, its efficiency of dust collection can be greater than 98%, and dust exhausting concentration is lower than 50mg/m ³, when adding clear water, desulfuration efficiency, as adds an amount of akaline liquid greater than 70%, also can obviously improve.The binary vortices desiccant body, simple in structure, resistance coefficient is lower, running is reliable, can make the outlet smoke moisture be lower than 3%.Reciprocating type residual cake valve can make the sediment after hardening recover moisture and smooth discharge again.The utility model is compared with prior art, have simple in structure, compact, characteristics such as energy consumption is low, operating cost is low, reliable.Applicable to various boilers, work kiln, the harmful substance in some chemical emissions is also had higher purification efficiency.
