Abstract
The utility model relates to a purification device for extracted waste gas. The purification device adopts the structure that extracted waste gas at the top of an extraction tank enters the lower part of a water purification box through a duct connected with the lower part of the water purification box, and then is subjected to water washing and impurity filtrating to realize rough purification, and the roughly purified extracted waste gas enters the inlet of a blower through a purification duct from the top of the water purification box; the extracted waste gas is extracted by the blower, and then is conveyed to a combustion section of high-temperature combustion equipment through a duct, and organic matters in the extracted waste gas are subjected to combustion or high-temperature oxidation in the high-temperature equipment to generate nontoxic and innoxious carbon dioxide and water vapor, so that the extracted waste gas is completely purified. The high-temperature combustion equipment comprises a roasting furnace or an industrial boiler. According to the purification device provided by the utility model, the roasting furnace or the industrial boiler used in a conventional enterprise of the extraction process is adopted, so that the investment is less; adding materials or catalysts can be eliminated, so that the running cost is very low; the purification device is excellent in purification effect, is stable and reliable, avoids secondary pollution, prevents waste gas from escaping in an extraction workplace, and is conducive to the health of operating personnel.
Description
Technical field
The utility model relates to a kind for the treatment of apparatus of waste gas, belongs to disposal of waste gas, water and industrial residue field, particularly a kind of purifier that extracts waste gas.
Background technology
In industrial production, a lot of occasions are used extraction process, particularly the industry such as chemical industry, rare earth and uncommon precious metal smelting.Extraction process extractant used is generally organic matter, as kerosene, secondary octanol etc.The waste gas that extraction process produces contains a small amount of or micro-organic extractant.The current processing mode to this type of extraction waste gas mainly contains two kinds: a kind of is that extraction tank is added a cover, and covers and establishes a blow-down pipe that has a certain altitude, other local sealings; Which is implemented convenient, can greatly reduce the loss of extraction waste gas, but it does not purify the organic matter in waste gas, and operation field still has pungent smell, still has a small amount of organic matter to spill in atmosphere and pollutes.Another kind of mode is to provide power by air-introduced machine, and extraction waste gas is carried out after partially recycled processing by modes such as alkali spray, catalytic oxidation, electric decomposition, after processing, by standard aiutage, arranges outward.The second way can effectively be processed most of extraction waste gas, but has open defect: the one, and the treating apparatus of which takes up an area greatly, investment is large; The 2nd, the operating cost of which is higher; The 3rd, in the process of processing extraction waste gas, produce waste water, cause secondary pollution; The 4th, which cannot guarantee the effect thoroughly purifying to the extraction waste gas containing micro-content organism.
Summary of the invention
The deficiency that does not add processing or existing processing mode for current extraction waste gas, the purpose of this utility model is to provide the extraction waste gas purification apparatus that a kind of clean-up effect is good, reliable and stable, there is no secondary pollution.
For solving the problems of the technologies described above, the technical solution of the utility model is: the extraction waste gas at extraction tank top enters water purifying box bottom by the pipeline being connected with water purifying box bottom, extraction waste gas through washing filtering impurity, obtain after preliminary purification, by water purifying box top, by purifying pipeline, entering the entrance of air blast; Extraction waste gas is extracted by air blast, by the pipeline being connected with high-temperature combustion equipment, input the burning zone of high-temperature combustion equipment, organic matter in extraction waste gas burns or high-temperature oxydation at high-temperature service burning zone, generate nontoxic carbon dioxide and water vapour, thereby extraction waste gas obtains thoroughly purification.Extract waste gas from the collection of extraction tank top until send into high-temperature combustion equipment burning zone all in air-tight state, extraction tank is interior in micro-vacuum state.Described high-temperature combustion equipment is roaster or Industrial Boiler.
The top of described water purifying box is provided with water intaking valve, and the bottom of water purifying box is provided with discharging valve; By regulating the height of water level of water purifying box to adjust in extraction tank in micro-vacuum state, prevent excessively volatilization and the loss of organic phase in extraction tank.When described air blast is constant speed air blast, at water, purifies pipeline stage casing the extraneous bypass valve of connection is set, in order to adjust the micro-vacuum state in extraction tank, prevent excessively volatilization and the loss of organic phase in extraction tank.Described air blast is frequency control air blast, by the frequency control of air blast, adjusts the micro-vacuum state in extraction tank, prevents excessively volatilization and the loss of organic phase in extraction tank.
When the burning zone of high-temperature combustion equipment is during in negative pressure state, extraction waste gas directly can be sent into the burning zone of high-temperature combustion equipment by pipeline; When the high temperature burning zone of waste gas can not provide the transmitting power of extraction waste gas, can provide power by air blast, the extraction of extraction waste gas is sent into the high-temperature combustion equipment purification of burning.
the beneficial effects of the utility model:1, this device is easy and simple to handle, purifies thoroughly, utilizes general roaster or the Industrial Boiler being all equipped with of enterprise of existing employing extraction process, and investment is few; Without adding any material or catalyst, operating cost is extremely low.
2, this device is applicable to the purification containing extremely low concentration organic matter extraction waste gas, and clean-up effect is good, reliable and stable, there is no secondary pollution, extraction operation place without waste gas overflow, without the pungent smell of extractant, be conducive to operating personnel's occupational health.
While 3, extracting waste gas burning, can provide energy for high-temperature service.
Accompanying drawing explanation
