Abstract
The utility model discloses a landfill gas purification system comprising a condensed water separator, a pressurization fan, a buffer tank, a dehydrating device, a desulphurization device, a dryer, an air storage tank and a pressure-stabilized tank which are connected in sequence, wherein an inlet of the condensed water separator is connected with a main gas collecting tube; a pipe arranged between the condensed water separator and the pressurization fan is connected with a metering valve; and dry padding is arranged in the dryer. The landfill gas purification system can be used for purifying landfill gas in the extracted refuse landfill through the processes of condensed water separation, dehydration, desulphurization and drying; and the condensed water separator is used for removing water in the landfill gas, so that the pressurization fan can be effectively prevented from being corroded, and the landfill gas can be recycled.
Description
Technical field
The utility model relates to the landfill gas purification techniques of refuse landfill, is specifically related to a kind of landfill gas cleaning system.
Background technology
Along with rapid economic development in recent years, Domestic Refuse rapidly increases, and it is the processing mode the most generally adopted at present that house refuse is processed in sanitary landfills, and house refuse, after sanitary landfills, can produce and take methane and the carbon dioxide landfill gas as Main Ingredients and Appearance.If do not carry out suitable collection emission treatment, landfill gas knows from experience accumulation in landfill yard, to external leakage, diffusion or move in soil, easily causes the junk-heap body avalanche and to surrounding environment with human health works the mischief and harmful effect.When methane reaches finite concentration, can set off an explosion and fire; Also may cause that ground water hardness raises; Methane in landfill gas can cause scarce the supporting of landfill yard and surrounding plants Yin Gen district and dead and aggravation global warming to airborne release and diffusion; Trace toxic gas in landfill gas causes damage etc. to the mankind's major organs.Because the content of methane in landfill gas is generally 50% left and right, its calorific value is about half of natural gas, suitable with town gas, and landfill gas is a kind of resource that can recycle.But refuse landfill is generally to adopt sky is discharged to eliminate safe hidden trouble, and except the waste resource, more environment and common people's health is caused to harmful effect like this.Along with the energy and the shortage of resources problem day by day serious, people more and more pay attention to this renewable resource of rubbish landfill gas, the landfill gas in garbage loading embeading need to be extracted, rubbish landfill gas just can be effectively utilized after purifying.
The utility model content
The purpose of this utility model is to provide a kind of landfill gas cleaning system, the landfill gas extracted in garbage loading embeading can be purified, wherein purification process has condensed moisture from, dehydration, desulfurization and drying, condenswater separator is removed the moisture content in landfill gas, effectively prevent the booster fan corrosion, realize the landfill gas recycling.
The purpose of this utility model is achieved through the following technical solutions: a kind of landfill gas cleaning system, comprise the condenswater separator, booster fan, surge tank, dewater unit, desulfurizer, drier, air accumulator and the vacuum tank that connect successively, the entrance of described condenswater separator connects gas collecting main pipe, on pipeline between described condenswater separator and booster fan, be connected with metering valve, described drier inside is provided with dry filler.
The outlet of described vacuum tank is connected with safety valve.
Operation principle of the present utility model: rubbish, after sanitary landfills, can produce and take methane and the carbon dioxide landfill gas as Main Ingredients and Appearance.A kind of landfill gas cleaning system is for the refuse landfill of having bound or the landfill zone of having completed, also can be used for the landfill yard still moved, landfill gas is extracted out, the landfill gas of collecting by after purifying for generating, generation electric power utilizes, and wherein purification process has condensed moisture from operations such as, dehydration, desulfurization, dryings.The entrance of condenswater separator connects gas collecting main pipe; the landfill gas of collecting enters condenswater separator; condenswater separator is removed the moisture content in landfill gas; and cause the composition of aftertreatment device metal surface to peel off when further protection is avoided by the landfill gas collision of carrying, impact, prevent landfill gas entrained liquids corrosion booster fan.Then gas enters surge tank, dewater unit, desulfurizer, drier, air accumulator and vacuum tank successively, after gas reaches the recycling standard, carries out the utilization of resources.
In sum, the beneficial effects of the utility model are: the landfill gas extracted in garbage loading embeading can be purified, prevent landfill gas in landfill waste or landfill yard is blasted, wherein purification process has condensed moisture from, dehydration, desulfurization and drying, condenswater separator is removed the moisture content in landfill gas, effectively prevent the booster fan corrosion, after purifying, gas can be converted into electric power or, as the clean energy resource burning, realize the landfill gas recycling in generating set.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The title of mark in accompanying drawing: 1-gas collecting main pipe; 2-condenswater separator; 3-metering valve; 4-booster fan; 5-surge tank; 6-dewater unit; 7-desulfurizer; 8-drier; 9-air accumulator; 10-vacuum tank; 11-safety valve; 12-dry filler.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
Embodiment: as shown in Figure 1, the utility model comprises condenswater separator 2, booster fan 4, surge tank 5, dewater unit 6, desulfurizer 7, drier 8, air accumulator 9 and the vacuum tank 10 connected successively, the entrance of described condenswater separator 2 connects gas collecting main pipe 1, on pipeline between described condenswater separator 2 and booster fan 4, be connected with metering valve 3, described drier 8 inside are provided with dry filler 12.
The outlet of described vacuum tank 10 is connected with safety valve 11.
During the utility model work operation: a kind of landfill gas cleaning system is for the refuse landfill of having bound or the landfill zone of having completed, also can be used for the landfill yard still moved, landfill gas is extracted out, the landfill gas of collecting by after purifying for generating, generation electric power utilizes, and wherein purification process has condensed moisture from operations such as, dehydration, desulfurization, dryings.The entrance of condenswater separator 2 connects gas collecting main pipe 1; the landfill gas of collecting enters condenswater separator 2; the moisture content that condenswater separator 2 is removed in landfill gas; and cause the composition of aftertreatment device metal surface to peel off when further protection is avoided by the landfill gas collision of carrying, impact, prevent landfill gas entrained liquids corrosion booster fan 4.Then gas enters surge tank 5, dewater unit 6, desulfurizer 7, drier 8, air accumulator 9 and vacuum tank 10 successively, after gas reaches the recycling standard, carries out the utilization of resources.
As mentioned above, just can realize preferably the utility model.
