Description

A kind of lead smelting exhaust processing system
Technical field
The utility model is related to operation, transport class, and the method contacted using solution-air purifies exhaust gas apparatus, espespecially a kind of lead Smelting exhaust processing system.
Background technology
The purpose gathered dust is the high arsenic for producing retailoring of blast furnace, low-sulfur flue gas is through gravitational settling, electrostatic precipitation two Level dry method and inverse spouted Reeb scrubbing tower, the dedusting of packed tower two-stage wet cooling, two sections of ammonia suction method desulfurization process, accomplish to smelt cigarette Gas qualified discharge, while reclaiming element sulphur, the general principle of gravitational dust collection enters after gravity settling chamber for ash-laden gas, and flowing is horizontal Sectional area expands, and flow velocity reduction, heavier particle dirt is slowly settled to ash bucket under gravity, and the general principle of electrostatic precipitation is Ash-laden gas makes grit charged during being ionized by high voltage electric field, and grit is sunk in the presence of electric field force Product separates grit in dust collecting electrode from dusty gas, and the basic process of dynamic wave scrubbing tower is high-speed liquid directive The gas of reverse flow, makes cleaning solution four dissipate splashing using the momentum of flue gas in reverse jet tube, and cleaning solution reaches dynamic flat with flue gas Heng Chu forms metastable strong turbulence Thysanophyllum, is fully contacted in this region gas-liquid, is updated at a high speed with contact surface, in flue gas Dust and SO2 by the liquid film parcel of turbulent flow, dissolving and enter gas-liquid separation groove, in the process, gas quilt with cleaning solution The basic process in adiabatic saturation state, packed tower is cooled to spray onto filler through liquid distribution trough from tower top for liquid, and Flowed down along filler surface, gas is sent into from bottom of towe, through distribution device in gas-fluid(Minor diameter tower does not set distribution device in gas-fluid typically)Point After cloth, the space of packing layer is continued through in adverse current with liquid, on filler surface, gas-liquid two-phase close contact carries out mass transfer, Arsenide and flue dust in flue gas largely enter flue gas after cleaning solution, cooling and enter ammonia suction desulfurizer.
The pattern fixed more than the lead smelting desulfurized dust collection column of prior art using filler carries out desulfurization, and such pattern is present Larger defect, because filler is contacted with tail gas for a long time, causes filler to reach that the full state of absorption causes to adsorb.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of lead smelting exhaust processing system, and the system architecture is closed Reason, easy to use, by gravitational dust collection and the principle of floating stuffing dedusting, the sufficiently effective flue dust in tail gas is adsorbed Processing.
In order to solve the above technical problems, the utility model provides a kind of lead smelting exhaust processing system, including precipitator tower, Scrubbing tower, air inlet, air outlet, connecting tube, blast cap, ventilation duct, it is characterised in that:Precipitator tower is hollow cylindrical structural, It is provided with to be provided with some ventilation ducts, ventilation duct in the middle part of air inlet, precipitator tower on the left of precipitator tower bottom and is provided with blast cap, divulges information Ttom of pipe end is provided with dreg collecting slot, and dreg collecting slot bottom is provided with the middle part of deduster, precipitator tower to be provided with gas skirt, gas skirt and set There are some tuyeres, precipitator tower middle and upper part is staggeredly equipped with some swash plates, and precipitator tower top is provided with packing layer, precipitator tower top Heart position is provided with connecting tube, and the other end of connecting tube is arranged on scrubbing tower bottom, and scrubbing tower bottom is provided with air-distributing disc, washing Washing frame is provided with the middle part of tower, washing frame is internally provided with the right side of some air floatation balls, scrubbing tower bottom and is provided with circulation pipe, circulates Pipe bottom is provided with circulating pump, and circulation pipe top, which is provided with some branch pipes, branch pipe, is provided with some nozzles, and scrubbing tower top is set Gas-liquid separator is equipped with, scrubbing tower top center is provided with air outlet.
Operation principle of the present utility model:
By reasonable design of the present utility model, the product design is rationally, easy to use, passes through the phase of ventilation duct and blast cap Mutually coordinate, change the flow direction of flue gas, the flue dust in flue gas is once settled by the pattern of gravitational settling, then by handing over Molecule in flue gas is carried out secondary settlement by the baffle plate of mistake design, and then the harmful substance in flue gas passes through in scrubbing tower Washing frame is removed, and is constantly fluctuated by air floatation ball in washing frame, and the contact area of increase flue gas and alkali lye makes cigarette Sulfide in gas is effectively removed, and is then effectively removed by gas-liquid separator.
