Technical background
Coal tar is also known as coal cream, tar oil, liquor carbonis detergens.It is a kind of black or pitchy obtained during coking of coal Viscous liquid, proportion is more than water, and flammable and be corrosive with certain dissolubility and special stink, coal tar is coking work One of product in the raw gas that industry pyrolysis of coal is generated, its yield accounts for the 3%-4% of shove charge coal, and at normal temperatures and pressures its product is in Dark thick liquid, tar problem is the biggest obstacle for affecting gasification gas to use, and tar piles up meeting blocking pipeline, pollutes combustion gas Hole, makes supply normally to run, so thick combustion gas must carry out the removal of tar.
Gasifying stalk equipment is a complexity and huge system, and in such a system, spray column tar capturing device is not only The removing tar in combustible gas of the task is carry, while the using for combustible gas purifying plant also for next step creates indispensable bar Part.Coal tar is one of product in the raw gas that gasifying stalk is generated, and at normal temperatures and pressures its product is in black viscous liquid, Tar problem is the biggest obstacle for affecting gasification gas to use.For a long time, people are devoted to developing high performance tar always and catch Acquisition means, but existing tar capturing device also haves the shortcomings that certain, such as and tar absorption efficiency is low, and service life is short Deng.
Utility model content
The purpose of this utility model is just to provide for a kind of simple structure, easy to adjust, strong applicability, can realize slightly The water vapour spray column tar capturing device that tar is removed in combustion gas, it is possible to achieve the zero-emission of tar and the recovery of tar are sharp again With.
The purpose of this utility model is achieved through the following technical solutions:A kind of water vapour spray column tar trapping dress Put, including the housing of hollow cylindrical structure, the housing bottom sealing, top is provided with gas outlet, it is characterized in that, the shell Some ultrasonic pneumatic energy nozzle, movable flashboard, the expanded graphite absorption of annular conduit and annular conduit connection are provided with body cavity Plate;The housing sidewall is provided with the air inlet being connected with annular conduit, and the ultrasonic pneumatic energy nozzle is evenly arranged in annular conduit Downside, the movable flashboard is placed between annular conduit and expanded graphite adsorption plate;The housing hollow inner bottom part is provided with Jiao Oil reclaims chamber, and tar reclaims chamber and is respectively provided on two sides with aspiration pump, oil leaking hole.
The annular conduit is double-decker.
The air inlet is connected with gasification furnace gas outlet.
The movable flashboard is connected with cylinder, controls flashboard by cylinder and opens and closes.
The sprayable micron-sized minute particles of the ultrasonic pneumatic energy nozzle.
The particle diameter of the minute particles is less than 50 microns.
Spray column tar capturing device is provided with double layers of sprinkling chamber in the utility model, and two rings are correspondingly provided with tower body Shape water pipe and air inlet;The sprayable micron-sized minute particles of ultrasonic pneumatic energy nozzle, significantly carry with very big chemism The high Percentage bound with suspension coke tar particles, to realize the maximization of tar amount of collected and the minimum of water consumption;Ultrasonic strength spray Head is arranged on annular conduit using space circle multiple spot arrangement form, and this kind of arrangement form can be effectively ensured nozzle injection The uniformity of water vapour, so as to realize thick combustion gas in tar quick cooling with catch.
Housing bottom be provided with tar reclaim chamber, expanded graphite adsorption plate based on expanded graphite macroporous structure and its own Calendered flexible, expanded graphite adsorption plate can adsorb to the tar in water vapour, also can reclaim institute when movable flashboard is closed The tar of absorption;When expanded graphite has adsorbed a certain degree of tar water, movable flashboard is closed under cylinder action, opened Aspiration pump, part macropore is compressed under certain suction filtration suction function(Adsorb expanded graphite by being evacuated pumping suction function Store oil space is compressed in plate), the oily substance for being adsorbed is extruded out, causes adsorbance to be obviously reduced, and now opens leakage Tar is drawn and carries out recycling by oilhole, finally realizes tar zero-emission and the utilization completely of tar energy.
The utility model solves the problems, such as the difficult removal of coal tar in thick combustion gas, after thick combustion gas is passed through in housing, space The ultrasonic pneumatic energy nozzle of circular multiple spot arrangement form sprays less than 100 microns of minute particles, and is brought using air-atomizing Gas inertia power, in spray tower bottom, expanded graphite adsorption plate is set, the tar in thick combustion gas is collected, when expanded graphite absorption During a certain degree of tar water, under certain suction filtration suction function, the oily substance for being adsorbed is extruded out, opens oil leak Tar is drawn and is recycled by hole, finally realizes tar zero-emission and the utilization completely of tar energy, be can be widely applied to In various thick combustion gas purification systems.
Usefulness of the present utility model:
1st, the utility model sprays less than 50 microns of minute particles, in addition in mist using ultrasonic air-atomizing technology Substantial amounts of anion will be discharged during change, it produces electrostatic reaction with the coke tar particles of floating in combustion gas so as to precipitate, therefore The Percentage bound of spray suspension coke tar particles can be greatly improved, the maximization of tar amount of collected and the minimum of water consumption is realized.
2nd, the utility model is effectively protected using the spray pipe structure of the space circle multiple spot arrangement form of double layers of sprinkling form The uniformity of droplet size distribution in card spray chamber, the Quick uniform for realizing tar in thick combustion gas absorbs.
3rd, the utility model adopts expanded graphite adsorption plate structure, according to expanded graphite macroporous structure and the calendering of its own Flexibility, can squeeze out the oily substance for being adsorbed under certain suction filtration suction function, cause adsorbance to be obviously reduced, and realize Rapidly and efficiently absorption containing tar vapor and recovery.
The features such as the utility model has simple structure, easy to adjust, strong adaptability, not only removes tar to combustion gas matter The impact of amount, and realize tar zero-emission and the utilization completely of tar energy.
Description of the drawings
