Description

The defluorinate desulfation dust-extraction device
Technical field
The utility model relates to a kind of environmental protection equipment, particularly relates to a kind of defluorinate desulfation dust-extraction device purified for dusty gas.
Background technology
The backwardness of China to the solder flux exhaust gas treatment technology, cause solder flux exhaust emission situation still very severe.The waste gas that the fysed flux production process produces belongs to uncontrollable discharge, and waste gas contains dust.Contain in addition: the compositions such as carbon dioxide, sulfur dioxide, sulfur trioxide, hydrogen fluoride, water, hydrogen fluoride gas wherein is very serious to the murder by poisoning of crops in surrounding environment, can not normally tie fringe after particularly can causing the corn flowering, cause the underproduction even to be had no harvest, so the improvement of waste gas containing fluoride is very necessary and urgent.
Traditional wet flue gas dedusting defluorinating and dedusting device is generally external tower type, through alkali lye hydrofluoric purpose in tower body inside reaches and removes flue gas the spray of flue gas, washing.Because the contact-making surface of gas-liquid two-phase in this course is little, contact slowly, the collision dynamics caused inefficient result not.Chinese patent CN2414827Y and Chinese patent CN2517481Y disclose has the technology that solves the flue gas ash removal defluorinate; Chinese patent ZL200510040799.8 discloses a kind of fume desulfurizing, defluorinating and dedusting device.Existing this type of flue gas processing device, on the one hand because reaction process is short, can not meet the processing of relatively large smoking gas containing fluorine; On the other hand, the higher flue gas (as solder flux factory flue gas) for some dustiness can't be removed a large amount of dusts in the process of reaction, makes a large amount of dusts cause equipment to stop up, and pipeline blockage, system such as can't normally move at the problem.The waste gas produced for the fysed flux production process, go back the more satisfactory technology of neither one both at home and abroad it administered.The weak point that the technology such as the cloth bag generally used now, whirlwind, static, moisture film exist is: original equipment cost is high; System is easily stopped up; Dedusting and dehydrofluorination can not synchronously complete; The environmental protection operating cost is too high; Defluorination effect is poor.So prior art is not suitable for the environment protection treating of solder flux enterprise and the optimum organization of energy-saving and emission-reduction.
As can be seen here, above-mentioned existing defluorinate desulfation dust-extraction device, obviously still have inconvenience and defect, and urgently be further improved.In order to solve the problem of its existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but have no for a long time applicable design always, by development, is completed, and this is obviously the problem that the anxious wish of relevant dealer solves.
Summary of the invention
The purpose of this utility model is, providing a kind of can carry out the dusty gas purifier of defluorinate desulfurization and dedusting to dusty gas.Efficiency of dust collection of the present utility model is far above conventional spraying and dedusting, with conventional dry method dust, compares and the composition such as dehydrofluorination simultaneously, can also remove the compositions such as sulfur dioxide.
The purpose of this utility model and to solve its technical problem be to adopt following technical scheme to realize.The utility model is a kind of defluorinate desulfation dust-extraction device, it is characterized in that: described defluorinate desulfation dust-extraction device comprises: housing, air inlet, atomization larynx, minor air cell, vortex board, blocking solution plate one, spray nozzle, demister, blocking solution plate two, gas vent; Air inlet is positioned at lower housing portion, the atomization larynx is set in inlet plenum, the atomization larynx is nested in inlet plenum, connection minor air cell, atomization larynx rear end, minor air cell is nested in the housing middle part, vortex board is equipped with in inside in minor air cell, there is blocking solution plate one rear end, minor air cell, blocking solution plate one rear end connects exhaust chamber, and exhaust chamber is nested in housing top, and exhaust chamber upper, middle and lower section is equipped with spray nozzle, exhaust chamber has pipeline to connect circulating pump, demister is equipped with on exhaust chamber top, and the demister top is equipped with blocking solution plate two, and blocking solution plate two tops are equipped with gas vent.
The purpose of this utility model and solve its technical problem and can also be further achieved by the following technical measures.
