Abstract
The utility model relates to a lead dust and lead fume purifying system which structurally comprises a collection cover and a purifying tower, wherein a first draught fan and a venturi pipe are connected onto a connection pipeline between the collection cover and the purifying tower, a water seal tank is arranged at the bottom of the purifying tower, and a circulation water pump is connected between the water seal tank and an inlet of the purifying tower through a connection pipeline. The lead dust and lead fume purifying system overcomes the shortcomings of the previous de-lead device, improves purifying efficiency of lead fume and lead dust to be higher than 99% and obviously improves environment conditions and air quality of lead fume and lead dust production places. The lead dust and lead fume purifying system has the advantages of being reasonable in structure, light in weight, convenient to install and maintain, reliable in operation, low in noise, good in purifying performance, high in dedusting efficiency and the like and can be widely used in leaded waste gas purifying and dedusting of industrial production occasions.
Description
Technical field
The utility model relates to a kind of isolation of purified equipment, a kind of specifically lead dust and lead fume cleaning system.
Background technology
Lead fume and lead dust are mainly derived from the production operation of mining, smelting, soldering, products containing lead and the waste gas of doped fuel burning back generation etc. in the environment.Usually under the state, lead fume and lead dust are colourless, odorless, be present among the atmosphere with aerosol state, and according to microscopic examination, lead fume and lead dust particle diameter major part belong to respirable dust about 0.1 μ m, very big to human harm.The air that generally contains lead fume and lead dust gets into body through respiratory tract, alimentary canal; Accumulate in bone and liver,kidney,spleen and brain etc. and locate; To damage nervous system, hemopoietic system, urinary system, digestive system and reproductive organs; Cause symptoms such as anaemia, muscle arthralgia, digestive system are unusual, terminal neural paralysis, children's health and intelligence development are obstructed.Therefore, reduce lead contamination, lead fume and the lead dust removed in the waste gas are the research topics that people pay attention to always.
At present, domestic existing lead fume cleaning equipment is essentially wet scrubber, like water-bath type, packing tower, spray chamber etc.; Mostly these are the water washing method, and the effect of purifying and dedusting is all not ideal, analyze its reason and are that mainly above wash mill is that the drop of borrowing cleaning solution to produce, liquid film, bubble etc. adhere to and aggegation each other the grit in the flue gas; Then grit is separated; But the chemical property of plumbous and lead oxide is more stable, and they are all water insoluble, and are the little dust of hydrophily; Therefore water can only wash the soot dust granule of greater particle size in the flue gas; And, adopting common sprinkling equipment for lead fume that is aerosol state and lead dust, its cohesion and assimilation effect are not ideal.
The utility model content
The purpose of the utility model just provides a kind of lead dust and lead fume cleaning system, to solve existing purifier deleading poor performance and inefficient problem.
The purpose of the utility model is achieved in that a kind of lead dust and lead fume cleaning system; Comprise collecting hood and purifying column; On the connecting line between said collecting hood and the said purifying column, be connected to first air-introduced machine and Venturi tube; Bottom at said purifying column is provided with water sealed tank, and water circulating pump is connected between the inlet of said water sealed tank and said purifying column through connecting line.
On the outlet communicating pipe of said purifying column, be connected to second air-introduced machine, be convenient to discharge the Purge gas in the purifying column.
Be connected to quench tower on the connecting line between said collecting hood and said first air-introduced machine,, can select to install to adapt to EGT than higher purification occasion.
Said purifying column is no filler spray purification tower or the board-like purifying column of eddy flow, can big lead button washing in the lead fume waste gas be removed like this.
Said purifying column, water sealed tank and Venturi tube are processed by fiberglass, to improve the corrosion resistance of related device, improve service life.
The utility model utilizes combining of purifying column and water sealed tank, the salpeter solution of in water sealed tank, packing into, acetum or aqueous slkali etc., and these solution can improve the permeability of lead fume and lead dust and affinity; Reduce the surface tension of lead fume and lead dust; Strengthened contacting of liquid pearl and flue dust thus, and can destroy the lead fume that is aerosol state, made its ionization; Soluble in water, thus corresponding raising is to the clean-up effect of lead fume and lead dust.
The utility model has made full use of Venturi effect; Changed the deficiency of original deleading equipment; The purification efficiency of lead fume and lead dust is reached more than 99%; Can obviously improve the environmental condition and the air quality that contain lead fume and lead dust production place thus, make airborne leaded safe level National standard, make the concentration of emission of lead fume and lead dust be lower than national standard.
The utlity model has rational in infrastructure, light weight, be convenient to I&M, reliable, characteristics such as noise is low, purifying property good, efficiency of dust collection height, can be widely used in the purification and the dedusting of the waste gas containing lead in the commercial production occasion.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, purifying column, 2, collecting hood, 3, smelting furnace, 4, quench tower, 5, water sealed tank, 6, water circulating pump, 7, second air-introduced machine, 8, Venturi tube, 9, first air-introduced machine.
The specific embodiment
As shown in Figure 1, the utility model comprises collecting hood 2, quench tower 4 and purifying column 1.The collecting hood 2 of glass steel is arranged on the top of smelting furnace 3, to collect the lead fume and the lead dust of smelting furnace 3 dischargings.Collecting hood 2 joins through pipeline and quench tower 4, through the temperature of quench tower 4 reduction is passed through lead fume and lead dusts.On the connecting pipeline between quench tower 4 and the purifying column 1, be connected to the Venturi tube 8 of first air-introduced machine 9 and glass steel,, improve the velocity of liquid assets of flue gas to make full use of Venturi effect.Purifying column 1 is to process with fiberglass, can be no filler spray purification tower or the board-like purifying column of eddy flow, so that the lead fume and the lead dust washing of greater particle size in the lead fume waste gas are removed.
Be provided with the water sealed tank 5 of glass steel in the bottom of purifying column 1, salpeter solution, acetum or aqueous slkali etc. are housed in water sealed tank 5, these solution can improve the effect that purifies with dedusting greatly.Water sealed tank 5 is connected through the inlet of water circulating pump 6 with purifying column 1, removes the purpose of contained lead fume and lead dust particulate in the waste gas to reach circulation.
Be provided with second air-introduced machine 7 in purifying column 1 exit, so that the discharge of Purge gas.
Function and effect for sophisticated systems; The utility model also can be equipped with gas on-line analyzer, PH control meter, differential pressure transmitter, pressure sensor, flow sensor, liquid level control meter, solid suspension densimeter, magnetic valve, frequency converter, switch board and accident warning device etc.; Each device all is to be presented on the display of switch board with electronic form; So that administrative staff come into plain view, be convenient to Operations, Administration and Maintenance.
