Description
Technical field
The utility model relates to the treating apparatus of landfill yard scope of operation foul gas, relates in particular to a kind of accumulation of heat autoxidation purifier that is used to handle foul gas on the landfill yard scope of operation (containing low-concentration methane).
Background technology
In recent years, China's trash processing way is diversified development, and land-fill method is the main mode of present stage China's garbage disposal, and the whole nation still has the house refuse more than 80% to adopt land-fill method to handle.Because China's house refuse has the characteristic of high Combination, high-moisture percentage, high organic, is easy to form stench especially.In processes such as the transfer of landfill yard, tiling, compacting, the uncontrollable discharge of a large amount of odorant pollutants diffuses in the atmosphere, and these foul gas pollutants can be divided into following five types by its composition:
One, sulfur-containing compound is like H
2S, SO
2, mercaptan etc.
Two, nitrogen-containing compound is like ammonia, amine, indoles etc.
Three, halogen and derivative are like chlorine, halogenated hydrocarbons etc.
Four, hydro carbons and aromatic hydrocarbon.
Five, oxygen-bearing organic matter is like alcohol, phenol, aldehyde, ketone etc.
These foul gas excitants are strong, and toxicity is big, and are bigger to environment and health influence.Because the foul smell problem of most landfill yards is not properly settled, therefore controlling around the stench of refuse disposal process has become the great people's livelihood difficult problem that governments at all levels pay much attention to.The garbage sanitary filling field environment is special, is open work basically, and area big, smelly source in operation area is wide, and foul gas is difficult to collect and handle.
Control measure to garbage sanitary filling field generation foul gas mainly contain following several kinds at present:
1, adopts unit, stratified operation, dwindle operating area and operation rapidly and efficiently as far as possible, use sand, soil and coverlay etc. in time to cover after the operation, discharge or block foul gas through the control foul gas and reduce the odor pollution influence to the path of distributing of air.
2, adopt conduit to collect landfill gas, prevent that foul gas in the landfill gas that landfill waste produces from outwards overflowing to distribute.
3, not timing ground sprays the deodorizing medicament to junk-heap body, through the composition effect in deodorizing medicament and the foul smell.
4, present domestic part landfill yard is laid membrane material and film downtake road through overlay area in the middle of the landfill yard, under suction function, collects the landfill foul smell, and the landfill foul smell that applies a torch collection carries out direct burn processing.But this employing torch burning is handled the mode of foul smell and is required its contained methane concentration higher; And the contained methane concentration of general job face new refuse is lower; And foul smell air quantity and composition fluctuation are bigger; Be prone to cause insufficient and unstable, the required auxiliary fuel consumption of burning big, thereby the foul smell treatment effect is not obvious.
Generally, fixedly the control of malodor source realizes that relatively easily the selection of technical method is also more, and the control technology in large-scale all-moving surface source then relatively seldom.Above-mentioned several kinds of processing modes mainly take some that the mode of its diffusion is sheltered, prevented to foul smell, but fail fundamentally to remove the odorant composition, fail fundamentally these odorous substances with great environmental risk effectively to be handled decomposition.How the effective odor pollution of controlling the landfill operation face in economy ground is distributed is one of difficult point of present efforts at environmental protection.
Mainly there is following problem in present refuse landfill: (1) foul gas is in the situation of uncontrollable discharge, very easily in air, spreads, and environment and residents ' health on every side brought very big negative effect; (2) the main at present method that the odor pollution influence is reduced in the path of distributing that adopts interim compacting, the discharging of control foul gas or blocking-up foul gas to air, but the effective processing means that contain low-concentration methane (below 1%) foul gas of collecting lacked to the landfill yard scope of operation.
