The air inlet of physical absorption unit in processing unit is connected to.
Referring to FIG. 1, the utility model provides a kind of mercurous emission-control equipment, including physical absorption unit and solid it is anti-
Absorptive unit is answered, the air inlet of physical absorption unit and the gas of liquid crystal display panel disassembling apparatus convey outlet, and physics is inhaled
The gas outlet of coupon member is connected to the air inlet of solid reaction absorptive unit, in which:
Physical absorption unit includes adsorption box 1 and the absorption group in adsorption box 1, for adsorbing mercury simple substance in exhaust gas
Part；
Solid reaction absorptive unit includes the solid filler 3 that can be reacted with mercury simple substance in exhaust gas.
Above-mentioned mercurous emission-control equipment, including physical absorption unit and solid reaction absorptive unit.Due to physical absorption

The reaction of mercury simple substance, realize processing again to mercury simple substance in exhaust gas, later, treated, and exhaust gas can drain into subsequent processing work
Sequence.
Mercurous emission-control equipment provided by the utility model using physical absorption unit in exhaust gas mercury simple substance it is preliminary
Processing again to mercury simple substance in exhaust gas of processing and solid reaction absorptive unit, can lifting device in exhaust gas mercury simple substance it is net
Change degree, and since solid filler 3 is solid, then two-phase haptoreaction can occur between exhaust gas and solid filler 3, so as to
The practical efficiency of reactant in solid filler 3 is promoted, cost absorption is reduced.
Therefore, above-mentioned mercurous emission-control equipment can be promoted by change to the treatment process of exhaust gas to mercurous exhaust gas
Treatment effeciency, and the practical efficiency of reactant can be improved, reduce cost absorption.
Based on the above technical solution, solid reaction absorptive unit includes transparent as a preferred implementation manner,
Glass tube 2 and the solid filler 3 that is filled in transparent glass tube 2, can change colour in reaction.
It should be noted that under normal conditions, most mercury are physically adsorbed unit absorption, usual adsorption efficiency is greater than
99%, and since the mercury of the overwhelming majority has been physically adsorbed unit absorption, then only near-transparent is being leaned in solid reaction absorptive unit
A small amount of reaction occurs for the position solid filler 3 of 2 port of glass tube, generates metachromasia, then operator can pass through solid
The color change of filler 3 estimates the adsorption saturation degree of physical absorption unit, thus to the absorption group in physical absorption unit
Part is replaced in time, to guarantee mercurous emission-control equipment provided by the utility model to the purifying rate of exhaust gas.
It is worth noting that, with the longtime running of equipment, in physical absorption unit absorbent module to the absorption of mercury gradually
Saturation, solid filler 3 changes colour obviously in glass tube at this time, whole section of region discoloration occurs, illustrates absorption of the absorbent module to mercury
It has been saturated.At this point, the dismantling work of waste liquid crystal panel and mercurous emission-control equipment can be stopped, after replacing absorbent module, then again
Open each device.
Based on the above technical solution, specifically, solid filler 3 is in the height containing 4.5%~5.5% concentration
Potassium manganate acidic mixed solution impregnation and the 3A molecular sieve being oven-dried.
It should be noted that mercury and solid potassium permanganate reaction, pass through Gao Meng in exhaust gas when mercurous exhaust gas passes through the pipeline section
The strong oxidizing property of sour potassium thoroughly absorbs mercury simple substance.Gas (exhaust gas) solid (3A molecular sieve) two-phase haptoreaction occurs simultaneously, improves
The practical efficiency of oxidant reduces cost absorption.
Further, since using the filling 3A molecular sieve of transparent glass tube 2, and the potassium permanganate (KMnO newly loaded4) 3A molecule
Displaing amaranth is sieved, when contacting mercurous exhaust gas, potassium permanganate can be reduced into manganese dioxide (MnO by mercury2) aobvious light grey, then pass through
The color change can indicate that whether physical absorption unit is saturated the absorption of mercury, and operator can be replaced by the prompt to inhale
It attached dose, that is, realizes physical absorption unit and the nearly saturation of mercury simple substance is adsorbed, also avoid wave caused by adsorbent is replaced too early
Take.
It should be noted that in transparent glass tube 2 3A molecular sieve be gradually reacted to posterior segment, replaceable transparent glass
The molecular sieve reacted away in pipe 2, to keep mercurous emission-control equipment provided by the utility model to mercury simple substance in exhaust gas
Purification efficiency.
In addition, it should be noted that, potassium permanganate is 5% concentration or so in preferred acidic mixed solution.
Based on the above technical solution, it is preferred that acidic mixed solution includes that the sulfuric acid of 30%~50% concentration is molten
Liquid.
Specifically, being formed in the potassium permanganate acidic mixed solution impregnation containing 4.5%~5.5% concentration and being oven-dried
The specific method of 3A molecular sieve include:
The sulfuric acid solution of 30-50% concentration is configured, it is (left to potassium permanganate concentration 5% that potassium permanganate solid is added wherein
It is right), after mixing evenly, 3A sieve particle is poured into, is infiltrated, since 3A molecular sieve has good characterization of adsorption, infiltration speed
Degree is quickly；Later, 3A molecular sieve is pulled out after draining, (60 DEG C) of low temperature drying, 3A molecular sieve is integrally in aubergine (Gao Meng at this time
The color of sour potassium).
It should be noted that in exhaust gas remaining micro mercury when being contacted with the 3A molecular sieve in transparent glass tube 2, and
KMnO4 reaction, and due to the presence of sulfuric acid, under acid condition, following reaction occurs:
3Hg+2KMnO4+2H2SO4→3HgSO4+2MnO2+4H2O+K2SO4
Based on the above technical solution, to prevent in transparent glass tube 2 3A molecular sieve to be lost, it is preferred that along gas
Flow direction, the both ends of transparent glass tube 2 are equipped with strainer, and the mesh diameter of strainer is less than the diameter of 3A molecular sieve.
Based on the above technical solution, it should be noted that absorbent module is sorptive material, and sorptive material
Including in active carbon, Ca-base adsorbent, metal absorbent (active carbon loading silver) and mineral adsorbent (zeolite or vermiculite)
It is a kind of.
Certainly, for cost the considerations of, preferably adsorbent material are active carbon.
Specifically, the mercurous exhaust gas of the generations such as dismantling liquid crystal display panel, first passes through air hose 4 and enters activated carbon adsorption case 1, it is big absolutely
Part mercury is tightly held by activated carbon, and then accesses potassium permanganate absorption tube, and absorbing reaction occurs for remaining micro mercury and potassium permanganate,
It is completely removed.
As a kind of optional embodiment, with continued reference to FIG. 1, the gas outlet of physical absorption unit and solid reaction absorb
It is connected between the air inlet of unit by air hose 4.
