Abstract
The utility model relates to a purifier for the welding smoke combined by the mechanisms of static electricity, filtration and settling, which belongs to the technique of the smoke purification. The purifier is technically characterized in that the thick powder dust is removed by adopting the gravity settling method, then the welding smoke fine particles are carried out the charge and centrifugation separation in the method of the static electricity rotational flow field, and the smoke are collected. At the same time, the aerosol formed with the smoke in the condensation process by the harmful smoke produced when welding is also carried out the charge coacervation into the relatively great particles to be collected. Finally, the purified smoke is exhausted to the atmosphere more cleanly through one level of filtration method again. The device is used for purifying the smoke in the welding technique and purifying the smoke produced in the similar technique.
Description
The present invention is a flue gases purification.It is the weldering fume purifier that the mechanism with static, filtration, sedimentation combines.Mechanism such as whirlwind, filtrate, water-bath are generally adopted in smoke abatement and dust control; Purifying harmful gas generally will be at pernicious gas of different nature.Administer with methods such as different sorbing materials or modifications.Yet welding cigarette purification techniques.Both at home and abroad majority is the employing scene purging method of bleeding.The now more advanced useful cloth bag filtration and the method for charcoal absorption.Britain's GB2032825A patent is that effect is reasonable.But it is cumbersome when changing the filtrate sorbing material.Handle trouble especially if these are regenerated with useless filtrates of crossing.As for simple method with the cloth bag filtration, can only smoke abatement, can not eliminate smog, can not purifying harmful gas.
The objective of the invention is for solving flue dust and the pernicious gas in the welding flue gas.The healthy problem of contaminated environment infringement workman.Used mechanism is that the welding flue gas is sucked in the purifier.Remove the meal dirt of welding slag and so on earlier with settling methods.Then.Carry out charged to flue dust and capture with the static vortex method.Pernicious gas molecule at high temperature producing simultaneously.The aerosol that forms with smog in condensation process also carries out charged cohesion and capture.At last, remove surplus dirt with filtration method again.Make it in clarifier, to discharge the air of cleaning.Through instrument detecting, smoke abatement and dust control efficient reaches 99.5%, and cleaning harmful gas efficient reaches 98%, and its absolute value all is lower than national labour hygiene standard.Smokeless to the light range estimation.
Structure content of the present invention, embodiment and accompanying drawing thereof as follows.Accompanying drawing one is the structure cutaway view.Figure two is outside drawings.
Accompanying drawings, concrete structure of the present invention and workflow, this device is by gravity settling chamber (1).Electrostatic rotating flow field (9) and filtration cloth bag (6).Wherein electrostatic rotating flow field (9) are cylindrical shapes, are installed in to filter cloth bag (6) the inside, and filter cloth bag with same dust stratification case (13).Brush (11) and brush (12) outward in also having that deashing uses is arranged on the deashing mechanism (7).And blower fan (2), high-voltage static power (8) corona wire (10), guidance panel compositions such as (5).Purifying workflow is along the figure upward arrow, will weld cigarette by blower fan (2) and introduce gravity settling chamber (1) from air inlet pipe (14), removes the meal dirt of welding slag and so on.Sending into electrostatic rotating flow field (9) by airduct (4) again makes flue dust carry out charged and centrifugation.Captured by dust collecting electrode (barrel) (8).The pernicious gas that high temperature produces during simultaneously to welding, the aerosol that forms with smog in condensation process also carries out the charged larger particles that is condensed into, and is captured.At last, refilter through cloth bag (6), so the clean air after purifying is discharged to atmosphere, every work half an hour.With a deashing mechanism of hand reciprocating sliding (7).Just electrostatic precipitation extremely can be gone up and cloth bag on the dust hung clean out, the workman is by to guidance panel (5).Blower fan (2) and electrostatic high-pressure power supply (3) are instructed control.
The advantage of this clarifier:
1. electrostatic field not only makes full use of the space and has dwindled the clarifier volume at the special construction of cloth bag the inside, and to the clean flue dust that in electrostatic field, is not captured.Once filter again, than simple purification efficiency height with cloth bag or static.
2. with regard to the clean electric system of high pressure, contacted not closed with shell, more safe and reliable than general high-voltage earthing method.
3. the structure of this electrostatic precipitator is a tubular, and flue gas passes through with cyclone mode again, so the time that dust is carried out corona is relative prolongation.There is not the corona blind area.Strengthened electric-field intensity.
4. because static and cloth bag adopt a deashing mechanism.Per half class pulls once.But with regard to dust out, so simpler than the periodic replacement filtrate of general absorption method.
Claims (3)
1, purify the weldering fume purifier of flue dust and pernicious gas in the welding flue gas, this clarifier has a gravity settling chamber (1), and an electrostatic rotating flow field (9) and one filter cloth bag (6), and one pay off grey mechanism (7), it is characterized in that:
A electrostatic rotating flow field (9) is columnar, and is located at filtration cloth bag (6) the inside,
This electrostatic rotating flow field (9) of b and filtration cloth bag (6) shared dust stratification casees (13).
2,, it is characterized in that filtering cloth bag (6) and electrostatic rotating flow field (9), a shared deashing mechanism (7) according to the described weldering fume purifier of claim 1..
3, according to the described welding fume purifier of claim 2., it is characterized in that being provided on the deashing mechanism (7) deashing in brush (11), outer brush (12).
