Description
Technical field
This utility model relates to a kind of discharge system, belongs to mercuric pollution treatment field.
Background technology
The physical property unique due to hydrargyrum and toxicity so that it is be widely used in industry and agricultural, but unprocessed just
Environment is caused severe contamination by the mercurous refuse of outer row.The dried wet deposition of Mercury In The Air, sewage irrigation, mud apply fertilizer and mercurous solid
The use of the accumulation of body garbage, organomercury pesticide and mercurous chemical fertilizer is all the main artificial source that hydrargyrum enters soil environment.By
It is a contact scar source mostly in these polluter, therefore is uneven pollution for soil environment, dirty at some areas Mercury in Soil
Dye may be the most serious.
From phase early 1960s, Japan has found since " minamata disease ", the whole world harm pay attention to day by day to mercury pollution,
And start the upsurge of mercury pollution research.Hg can enter soil environment by different approaches, through complicated physics, chemistry instead
Should, major part is trapped in soil with various forms, causes the pollution of surface water and groundwater, and meanwhile, hydrargyrum can also pass through crop
Edible part enters food chain, and gradually accumulates, thus finally constitutes a threat to health.The arable land that China is polluted by Hg
Area has 3.2 × 104hm2, annual " the hydrargyrum rice " produced reaches 1.9 × 108Kg, therefore the improvement to Soil Mercury Pollution is compeled with repairing
At the eyebrows and eyelashes.
In recent years, the research in terms of domestic the most use Low Temperature Thermal solution repairs mercury contaminated soil.Abroad, Environmental Protection in America
Administration has selected pyrolysismethod to repair points of contamination at more than 59, and the RAFAL KUCHARSKI of Poland is in laboratory and pilot scale scope
Inside exploring and repair mercury contaminated soil by Low Temperature Thermal solution, pyrolysismethod is the most successfully used for by the T.C Chang of TaiWan, China
Repair hydrargyrum heavily contaminated soil in the chlor-alkali plant of the Taibei.But, pyrolysismethod is mainly applied to repair oil etc. by U.S. Environmental Protection Agency (EPA)
Organic polluted soil, RAFAL KUCHARSKI uses in-situ low-temperature pyrolysismethod, and the temperature selected is relatively low, and T.C
Chang, because process is not farmland, does not consider the farming after soil remediation, has selected higher temperature.
Use Thermal desorption technology mercury in soils to be removed fast and efficiently, be repairing and treating high concentration mercury contaminated soil
Effective way, but existing Thermal desorption technology is while repairing and treating mercury contaminated soil, very big to soil fail, serious shadow
Ring the feasibility of soil agro-farming after repairing.Devise a kind of low temperature pyrogenation soil demercuration system for secondary, but this system is at soil
Pyrolysis demercuration heel row exists air entrance when going out soil affect internal system air pressure, and part may be arranged by soil containing mercury gas
Outlet enters into air-polluting problem in extraneous air.
Summary of the invention
The purpose of this utility model is: provide a kind of soil demercuration rotary furnace discharge system, with the soil designed by solution
Earth demercuration system exists air entrance when Soil Thermal solution demercuration heel row goes out soil affects internal system air pressure, and part is mercurous
Gas may be entered into air-polluting problem in extraneous air by soil outlet.
For solving the problems referred to above, intending using such a soil demercuration rotary furnace discharge system, described discharge system is arranged
Between rotary furnace and mercurous waste gas purification apparatus, including unloader and soil accumulator tank, unloader includes driving motor and unloading
Material impeller, discharging impeller is transversely correspondingly arranged at the bottom discharge mouth of the discharge end of rotary furnace, and soil accumulator tank is arranged at
The lower section of discharging impeller.
The upside of the discharge end of rotary furnace leads to guide pipeline and is communicated to mercurous waste gas purification apparatus, and mercurous waste gas is clean
Gasifying device outlet side is provided with air-introduced machine；
For ease of discharging, the downside of discharge end is pyramidal structure；
Preferably, drive and be provided with for the cold water pipe for driving electric motor temperature reduction cooling on motor；
Preferably, mercurous waste gas purification apparatus includes bag-type dust machine, packed tower and the activated carbon adsorption dress set gradually
Put；
Preferably, the upper end of guide pipeline is to be additionally provided with for detecting guide pipeline on domes, and guide pipeline
Interior gas temperature and the temperature sensor of pressure and Pressure gauge, it is possible to alleviate dust deposit on guide pipeline, it is simple to cleaning inducing QI
Laying dust on pipeline；
Compared with prior art, major advantage is that discharge end arranges unloader to this utility model, on the basis controlling discharging
On can also play the effect of trapping, it is simple to control the intake in burner hearth so that mercurous waste gas can be all introduced into follow-up
Mercurous waste gas purification apparatus in purify, mercury pollution treatment the most thorough；This system utilizes rotary furnace to realize in soil
The low temperature pyrogenation of hydrargyrum, it is possible to making being more uniformly distributed of the heating of soil everywhere, fully, in making soil, hydrargyrum departs from the most thorough, improves and takes off
Hydrargyrum effect.
