Abstract
The present invention relates to a high-effective charged preagglomeration type electric tar-trapping device, belonging to the field of environmental protection engineering technology, and relates to a gas purifying device in the coal conversion process. It is characterized by that it adopts a charged preaggomeration method to make the microfine tar atomized drops being in the thermal dirty gas or raw cake oven gas be previously agglomerated into large atomized drops. Said device includes external power supply, dirty (raw coke oven) gas inlet, precharging stage, mixing stage, main tar-trapping zone, clean gas outlet, valves and tar outlet.
Description
Technical field:
The invention belongs to field of environmental engineering, relate to the gas cleaning device in a kind of coal conversion processes, the charged pre-method of agglomeration of particularly a kind of employing makes the fine tar droplet in hot dirty gas or the raw coke oven gas be agglomerated into big droplet in advance.
Technical background:
The general structure that adopts single or multiple tar to capture the district of traditional electrical tar precipitator.But this traditional structure is directly introduced tar capture district with hot dirty gas or raw coke oven gas, fine tar droplet is not carried out preliminary treatment, causes it can not capture fine tar droplet effectively, and is not high to the overall purification efficiency of hot dirty gas and raw coke oven gas; In addition, the fine tar droplet that is mingled with in the coal gas also can cause follow-up line clogging.
Summary of the invention
The objective of the invention is directly hot dirty gas or raw coke oven gas to be introduced tar capture district in order to solve traditional electrical tar precipitator, can not capture effectively fine tar droplet, the fine tar droplet that the overall purification efficiency of hot dirty gas and raw coke oven gas is mingled with in the not high and coal gas also can cause the problem of follow-up line clogging.
A kind of high-performance charge pre-agglomerated electric tar corrector, it is characterized in that having increased pre-reunion district, the pre-district of reuniting is divided into pre-charged section and mixer again, the pre-charged section layout 2-8 root metal tube that goes in ring, every metal tube central authorities add a thin corona wire, and adjacent corona wire connects the positive pole and the negative pole of power supply respectively.After the energising, tar fog drops in and is forced to lotus in the electric field with positive charge or negative electrical charge, and adjacent corona wire is connected to the positive pole of power supply and negative pole and helps tar fog with the heteropolarity electric charge and drop in mixer and reunite in advance better.Mixer is one section blank pipe, and the tar fog of heteropolarity drops in this section interval and attracted each other by the effect of Coulomb force and pre-reunion takes place, and has realized that the tar droplet from the differentiation of small particle diameter to big particle diameter, helps the capture of fine tar droplet.Tar droplet positive and negative charge after taking place to reunite is in advance cancelled out each other, show electroneutral, catch in the tar district chargedly again, and under the effect of electric field force, move to receiving electrode main, be deposited at last on the receiving electrode, electrical tar precipitator has obtained promoting significantly to the arresting efficiency of fine tar droplet.
The basic principle of charged pre-reunion is that waste (dirty) coal gas is introduced the different electric field of polarity, makes wherein part tar droplet positively charged, and another part tar droplet is electronegative.After waste (dirty) coal gas confluxed, the tar fog of band heteropolarity electric charge dropped in and attracts each other under the effect of electric field force and reunite, and realizes that finally fine tar droplet is agglomerated into the purpose of big droplet in advance.
The present invention compares with traditional electrical tar precipitator, and have following two big outstanding advantages: (1) is to the arresting efficiency height of fine tar droplet.(2) can capture the ultra-fine tar droplet that traditional electrical tar precipitator can not trap effectively.
