Technical field
The utility model relates to a kind of oil gas conveying technology, particularly a kind ofly is used for the water-cooled transformation absorption waste gas recovering device that storage tank, tank car, oil truck, oil tanker, groove ship etc. use when escaping gases such as accumulating and unloading gasoline or other hydro carbons, lipid.
Background technology
Oil and products thereof is the mixture of multiple hydrocarbon, and light component wherein has very strong volatility.In exploitation, refining, accumulating, sale and the application process thereof of oil, all can some lighter liquid component vaporize inevitably, enter atmosphere, cause the loss of oil product and the pollution of atmospheric environment, have bigger harmfulness.
According to statistics, oil product is worked into the overall process of production marketing from the well site through refining, and the quantity of oil loss accounts for 3% of crude oil total output.Chinese crude output was 2.03 hundred million tons in 2010, and gasoline output is 7,675 ten thousand tons, and loss and environmental pollution are all very big.Conventional oil gas reclaims has absorption method, absorption process, condensation method, membrane separation process.The absorption process rate of recovery is not up to standard, and the condensation method energy consumption is big, and the membrane separation process investment is high, and membrane technology is by state's outer control.Existing absorption method retracting device adopts the reabsorber of big volume, infeeds identical liquid medium with oil-poor pump oil gas is absorbed, and process and technology is more complicated all.
Summary of the invention
The technical problem that the utility model will solve is the deficiency to prior art, has proposed a kind of water-cooled transformation simple to operate, that adsorption efficiency is high and has adsorbed waste gas recovering device.
The technical problem that the utility model will solve realizes through following technical scheme; A kind of water-cooled transformation absorption waste gas recovering device; Be characterized in: be provided with the left and right sides adsorption tower that is arranged side by side, the top and the exhaust gear of left and right sides adsorption tower join, and the bottom of left and right sides adsorption tower and oil gas distributor gear join; The oil gas distributor gear comprises that oil gas inlet pipe and oil gas go out pipe; The bottom connection of absorption control valve and left and right sides adsorption tower about the oil gas inlet pipe passes through respectively, oil gas go out pipe respectively through the bottom connection of left and right sides desorption control valve and left and right sides adsorption tower, and the outer end of oil gas inlet pipe and gas-liquid separator outlet are joined; The import of gas-liquid separator and oil gas reclaim house steward and join; The bottom of gas-liquid separator joins through tapping valve and recycling can, and oil gas goes out pipe and joins through vavuum pump and water-cooled heat exchanger, and the drain pipe and the recycling can of water-cooled heat exchanger join.
The technical problem that the utility model will solve can also further realize that the oil gas between vavuum pump and the oil gas distributor gear goes out on the pipe electric control valve is housed through following technical scheme.
The technical problem that the utility model will solve can also realize that further the top of recycling can is provided with the tail gas recycle pipe that the import of tail gas recycle pipe and said gas-liquid separator is joined through following technical scheme.
The utility model compared with prior art, through the setting of two adsorption towers, when an adsorption tower carried out adsorption operation, another adsorption tower carried out the desorption operation, and through water-cooled heat exchanger cooling, it is simple to operate, adsorption efficiency is high.This device is used for storage tank, tank car, oil truck, oil tanker, groove ship etc. when escaping gases such as accumulating and unloading gasoline or other hydro carbons, lipid; Can prevent that the volatilization of oil gas or other chemical gas from polluting atmosphere; Eliminate safe hidden trouble; Improve energy utilization rate, obtain considerable benefit repayment thereby reduce economic loss.
