Description
Technical field
the present invention relates to a kind of charging process and device of glance coal cleaning system, belong to asphalt smoke gas purifying technical field.
Background technology
the applicant in the application number that 2009 submit to is: 201110100654.8, in patent that name is called " a kind of Asphalt smoke purification method and device ", discloses a kind of asphalt smoke purifying system.It is by arranging a feeding-distribution device in filler bin outlet, adsorbent is sent into venturi reactor respectively through pipeline and produces the flue gas arm start position of flue gas larger kneading machine, cooler and forming machine, purify from the source of flue gas, to reach better clean-up effect.Simultaneously, because pipeline in system all receives washing away of powder from beginning section, avoid the tar in flue gas to stick on the inner-walls of duct comprising arm, prevent the blocking of the most of pipeline comprising smoke evacuation arm, avoid the thrashing because line clogging causes.But technique scheme in use also exists three main problems: the exhaust gas volumn one, produced due to kneading machine, cooler and forming machine each position and tar content are different, so the adsorbent needing to add inequality in each arm is for adsorbing the poisonous and harmful elements such as tar in flue gas.But because above-mentioned public technology scheme is by described feeding-distribution device sub-material, substantially average for bin blanking can only be divided into several parts, accurate, the continuous print that cannot realize every part of quantity of sorbent regulate.Therefore, the adsorption effect cannot realized ideal; Two, in above-mentioned public technology scheme, owing to using elephant trunk (common steel tube) after feeding-distribution device, carry adsorbent under gravity, for ensureing the normal blanking of elephant trunk energy, the setting angle of elephant trunk must be greater than the angle of repose of adsorbent, and the installation site which also limits filler bin must be normal reinforced to guarantee far above the feed location of each arm.But due to the restriction of production technology, often the installation site of adsorbent powder feed bin can not arbitrarily be arranged, in this case, for realizing the higher adsorbent powder feed bin conveying powder to position, often cause this partial adsorbates agent induction system complicated, construction, the operating cost of system are higher; Three, in public technology, the feeding quantity for adsorbent glance coal cleaning system controls, and is generally controlled the feeding quantity of adsorbent by the rotating speed of the revolution discharge valve controlling adjustable speed.But the equipment that the method uses is complicated, cost is high, and owing to turning round the architectural characteristic of feed valve, that is: rotated in housing by an inner impeller with repetitional structure, be filled in the die cavity of impeller from the adsorbent of housing upper feed bin or charging gear, adsorbent draws off by adsorbent with the bottom rotating to housing of impeller.So from each interval of impeller and compartment, discharge quantity is discontinuous stable.This feature, when turning round feed valve rotating speed and being lower, particularly evident.Because glance coal cleaning system adsorbent feeding quantity is less, about 0.3 ~ 1 ton/hour, therefore the general rotating speed of revolution feed valve rotating speed is all lower, therefore the stable of feeding quantity cannot be realized.
