Description
Technical field
The utility model relates to a kind of carrying out washing treatment machinery that is used for metallurgy industry.
Background technology
Bubbling washer is the lower heating value coal gas that cleans the imperial smelting furnace output with scour without sediment motion, makes coal gas remove the impurity grit and the task equipment of the use of regenerating.It is by the rotor of a high speed rotating and fixed stator bump current, current is clashed into into water droplet or water smoke capture flue dust in the coal gas, makes then gas-water separation to reach the effect that purifies coal gas.Because the coal gas that imperial smelting furnace produces includes a large amount of zinc oxide and plumbous oxide grit (being commonly called as blue powder), its cohesiveness is stronger, shape, arrangement mode and the angle of blade and the spacing between each layer blade in the design requirements choose reasonable rotor, should consider thus to improve efficiency of dust collection for the debunching action of water with to the wetting action of dust, consider to reduce the bonding of blue powder on blade again, be beneficial to cleaning, cut down the consumption of energy, satisfy the safety and steady operation of rotor a work period.
Machine one side has two gas inlets, and three nozzles are housed respectively, and the water smoke that is sprayed is caught a part of flue dust; Symmetrical side at machine has an air outlet, washing machine profile casing is a scroll casing shape, flue gas enters the washing machine middle part along the turbine line from inlet mouth, pass the rotor of high speed rotating, cleaning through main jet and big yield that washing nozzle sprays, discharge by symmetrical side venting port, make that outlet dust contained flue gas concentration is up to standard.Bubbling washer drives the rotor rotation by large power high voltage motor, and axle head is by packing box seal; The washing machine both sides respectively have three water mains to stretch into inside, and the watering tube is housed on the disk of high speed rotating, with a plurality of washing nozzles, the seizure middle part flue dust installed arranged side by side on the casing.
Because the unstable of the flue gas tolerance of imperial smelting furnace output does not have sophisticated calculation formula and method, bring certain difficulty for the design calculation of bubbling washer.Use for reference the iron-smelting blast furnace gas purification in the washing machine of our design and merge nonferrous smelting production actual process parameter, designed the smoke treatment amount from 36000m
3/ h～78500m
3The bubbling washer of/h satisfies production requirement through the production practice test, and reaches designed capacity.
