Description

A kind of autompulse blowback weld fumes clarifier
Technical field
The present invention relates to relate to the air purifying process field, relate in particular to the autompulse blowback weld fumes clarifier that a kind of while can be widely used in chemical industry, electronics, metal processing, pharmacy, food processing, automobile and other industries.
Background technology
Weld fumes is very complicated material, and the element of having found in flue dust is nearly more than 20 kinds, and that wherein content is maximum is Fe, Ca, Na etc., is secondly Si, Al, Mn, Ti, Cu etc.The harmful substances that mainly contains in weld fumes is Fe2O3, SiO2, MnO, HF etc., and that wherein content is maximum is Fe2O3, generally accounts for 35.56% of flue dust total amount, is secondly SiO2, and its content accounts for 10~20%, and MnO accounts for 5~20% left and right.
During metal solder, volume of smoke is suspended in working environment, and these flue dust are inhaled into the human lung and can have a strong impact on healthy, when serious, can also cause the diseases such as Chronic Mn Poisoning, electric welder pneumoconiosis disease, this shows, weld fumes is very harmful to operating personnel's.For eliminating this harm, present stage is all to adopt smoke and dust purifier to carry out purified treatment to the weld fumes in working environment, and known purifier for welding smoke mainly can be divided into by its purification style: three kinds of electrostatic, filtering type and absorption types.Electrostatic is generally to make minuteness particle in flue dust with electric charge by electrostatic interaction, make it be aggregated into bulky grain and remove, but this purification not only can not be removed pernicious gas, and electrostatic fume purifier, due to the needs high-field electrode, can produce micro-ozone, therefore, this electrostatic purifier not only can not effectively be removed pernicious gas, can increase the ozone content in environment on the contrary.The multiplex cloth bag of filtering type electric welding fume purifier or nonwoven are done filtering material, and its filter is very poor to fine grit filter efficiency, can not effectively eliminate the pernicious gas in flue dust simultaneously.The adsorption cleaning device is mainly the pernicious gas in absorbed air, usually adopts molecular sieve or active carbon as adsorbent.For eliminating the particle in flue dust, usually can before adsorbent, add filter, although this set composite can purify flue dust, filter resistance is large, needs high pressure positive blower to drive, efficiency is lower, and adsorbent is again cumbersome.
Summary of the invention
The deficiency existed for prior art, technical problem to be solved by this invention is, providing a kind of can not produce secondary pollution, not affect plant operations in guarantee, do not affect under the prerequisite in life-span of equipment, can effectively remove weld fumes, can remove toxic and harmful again, and can realize timing automatic clean filter cylinder, guarantee that equipment can normally move the autompulse blowback weld fumes clarifier that turns, increases the service life continuously.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of autompulse blowback weld fumes clarifier, comprise that one has the housing of dust shield, be provided with the filtrating smoke dust district with filter core be communicated with dust shield in housing, the filtrating smoke dust district is connected with the negative pressure ventilation district for suction is provided to dust shield, described negative pressure ventilation district is connected with the pure air collecting region, offer on housing and connect pure air collecting region and outside exhaust outlet, in described housing, be provided with act on filter core cartridge surface is assembled to the blowback control device that dust shoots down, described blowback control device is by being located at the outer gas storage bag of housing, stretching to the high pressure draught playpipe of filter core inside and the electric-control system of control magnetic valve break-make forms, described high pressure draught playpipe is connected with the gas storage bag by magnetic valve, described magnetic valve is electrically connected to electric-control system, described high pressure draught playpipe comprises that one has the body of closed inner chamber, the spray-hole that has a plurality of and described closed inner chamber to be communicated with along described body circumferential arrangement on the body surface.
Above-mentioned autompulse blowback weld fumes clarifier, described electric-control system is comprised of single-chip microcomputer, editor and display module, clock timing module and information storage module, described editor and display module, clock timing module and information storage module are electrically connected to respectively at single-chip microcomputer, and described magnetic valve is electrically connected to single-chip microcomputer.
