Description
Technical field:
The present invention relates to a kind of waste treatment apparatus in the environmental protection industry, more particularly relate to the device of the recovery of the heavy metal Hg in the mercurous waste residue of depleted.
Background technology:
Will inevitably produce a large amount of fragmentation pipes in the production process as many fluorescent tube bulbs factory and not reach useless pipe of service requirements; but can not melt down recycling; because contained the existence of the mercury that adds up in the production process in these glass; can not at will abandon again; so have to be crushed to mercurous waste residue stores; accumulate over a long period; having piled considerable scale can't handle; the strict again supervision of environmental administration of government; not treated qualified; this mercurous waste residue is inaccurate from factory; even fluorescent tube bulb factory is like this; other are relevant to be raw material with mercury; the mercurous waste that the enterprise of auxiliary material production and daily life abandon in producing is more and more serious to the harm that environment protection brings; the existing skill of bolt rope is asked data; still do not have the processing of finding this type of mercurous waste residue comparatively proven technique is arranged; therefore; a kind of new treatment process and treatment unit must be arranged; the heavy metal Hg that will be blended in the waste residue under the prerequisite that can not increase new environmental pollution is separated; make treated mercurous waste residue reach emission standard, can brickmaking; utilizations such as landfill.Such technology is the needs of environment protection, also is the utilization of resources, the good job of benefiting the nation and the people.
Summary of the invention
The present invention is with the above-mentioned purpose that is envisioned for, a kind of device of handling mercurous waste residue has been proposed, this treatment unit should have under the prerequisite of not polluted water and atmospheric environment can high-level efficiency and effectively the mercury that is blended in the waste residue is decomposed out, makes mercury to reclaim once more, utilizes.Waste residue after treatment then can reach national solid waste discharge standard, thereby can discharge under the prerequisite that does not influence environment.
Concrete technical scheme of the present invention provide a kind of cheaply, the separation waste residue of compliance with environmental protection requirements and the device of mercury.This device is the basic physics according to mercury, chemical property, center on the automatic removal of mercury device of a cover of the theme design of environmental protection, in charging totally-enclosed operation of holding device in the entire operation process of discharging, accomplish disposable charging, disposable discharging guarantees that in the entire treatment process, the Air quality of treatment plant reaches national environmental standard.
Technical scheme of the present invention is to realize by following concrete technical measures: a kind of treatment process of mercurous waste residue mainly comprises demercuration, collection mercury and filter three parts and form: the demercuration part mainly is by head tank, feed controller and the auger type demercuration stove of sealing and does not have mercury waste residue gathering barrel and combine; Collection mercury part mainly is to be combined by condenser and mercury collecting chamber; Filtration fraction mainly is by the particle adsorber, and two-layer charcoal absorption combines.A kind of treatment unit of mercurous waste residue, its characteristics are that it comprises: vent gas tower 1, blower fan 2, secondary activity charcoal adsorber 3, primary activity charcoal adsorber 4, water-cooled tube 5, mercury collecting chamber 6, condenser 7, particulate filter 8, auger core 9, demercuration heating furnace body 10, head tank 11, demercuration heating furnace body seat 12, mercuryvapour arm 13, mercuryvapour pipe 14, the logical close envelope Even of piping of point for measuring temperature 15 and no mercury waste residue discharge tank 16 each parts connects composition, wherein: the head end that is rolled into the demercuration heating furnace body 10 of column sealed cylindrical shell by steel plate, the end face center have auger core 9 Xiang Wai Even connect power, the Packed head tank 11 in cylinder body of heater 10 tops near this end face still has 3～5 mercuryvapour arms 13 and 3～5 points for measuring temperature 15 on the periphery of demercuration heating furnace body 10; Condenser 7 is water-jacketed condensers of an inner disc water-cooled tube 5, water coolant from C to advance, D is to going out; Elementary adsorber 4 is that built-in proportion is 0.55 common gac; Secondary adsorber 3 is that built-in proportion is 0.55 active carbon loading silver; The blower fan that blower fan 2 selects for use the per minute 2800 of high wind speed to change; Vent gas tower 1 is iron cylinder high tower, must exceed factory building and enclose Yang.
In the treating processes of whole mercurous waste residue, the mercurous waste residue that to handle earlier adds head tank 11 and seals, by control device mercurous waste residue is entered in the demercuration heating furnace body 10, ceaselessly push ahead and stir wherein mercurous waste residue by the spiral propeller in the stove, make it in the demercuration stove, carry out heat, mercury in waste residue flashes to mercuryvapour fully, break away from waste residue, the waste residue of handling enters last no mercury waste residue gathering barrel 16 automatically, mercuryvapour is then collected through each mercuryvapour arm 13 and is entered mercuryvapour pipe 14, mercuryvapour enters by water coolant 5 forms cooling in the condenser 7 of cyclic water jacket, the mercuryvapour that reaches normal temperature promptly can liquefy mercury and is entered mercury collecting chamber .6, remaining micro-dust, mercuryvapour is then by particle adsorber 8, elementary adsorber 4, after secondary adsorber 3 is handled, after reaching discharging standards, deliver to waste gas exhaust tower 1 emptying by blower fan 2.The small quantities of particles of wherein separating out can be put back to the demercuration stove and handle again, and the gac after the secondary absorption is by the recycling of professional gac factory.
The invention has the beneficial effects as follows conspicuous, whole device is reliable, effective, the entire treatment process is carried out under totally enclosed state, in the process of handling waste, do not cause new environmental pollution, but also can extract heavy metal Hg from waste, the waste residue after the extraction reaches national solid waste discharge standard, further brickmaking, landfill, the utilization of paving the way is an all comparatively successful technology of economic benefit, social benefit.
