At poisonous, the harmful smoke that produce in the above-mentioned every profession and trade welding procedure, present stage, the general smoke purifier that adopts carried out purified treatment, these smoke purifiers mainly are that the flue gas that welding produces is directly sucked after filter is discharged after filtering again, reach the purpose that harmful smoke is purified.But the inventor finds, the filter that purifies flue gas in the existing smoke purifier is generally taked thick effect, middle effect, the efficient concentration filter that superposes, each fits tightly closed assembly excessively between the filter core very close to each other, the filter of this structure is owing to be attached directly to filter to coercibility material and large particulate matter in the flue gas, cause the very fast obstruction of filter and lost efficacy, cause low, the poor filtration effect of filter clogging effect, shortened the service life of filter, to frequently change, the auxiliary material expense of smoke purifier is increased.
Summary of the invention
Based on above-mentioned existing in prior technology problem, the utility model embodiment provides a kind of modular filter device, is used in the fume cleaning equipment, has filter efficiency height, good filtration effect, the characteristics that need not frequently change.
The purpose of this utility model is achieved through the following technical solutions:
The utility model embodiment provides a kind of combined filter, comprising:
Framework, low efficient filter, medium effeciency filter, high efficiency particulate air filter and active carbon filter;
Described framework is provided with a plurality of installation sites, and each installation site adapts with low efficient filter, medium effeciency filter, high efficiency particulate air filter and active carbon filter profile respectively;
Described low efficient filter, medium effeciency filter, high efficiency particulate air filter and active carbon filter are successively set on each installation site of framework, and the 25~50mm that is spaced apart between each filter of back is installed.
As filtering material, its filtering accuracy is 5 microns to described low efficient filter by synthetic fibers, and filter efficiency is 90%.
Described medium effeciency filter adopts nonwoven and synthetic fibers as filtering material, is made into the cloth-bag type structure, and filtering accuracy is 0.5 micron, and filter efficiency is 85%.
Described high efficiency particulate air filter adopts ultra-fine glass filter paper as filtering material, and filtering accuracy is 0.3 micron, and filter efficiency is 100%.
The filter course of described active carbon filter adopts active carbon.
Described modular filter device also comprises: between the adjacent two layers filter sealing gasket is set and seals.
The technical scheme that is provided by above-mentioned the utility model embodiment as can be seen, among the utility model embodiment low efficient filter, medium effeciency filter, high efficiency particulate air filter and active carbon filter combination be arranged on and form the modular filter device in the framework, and make between the adjacent two-layer filter and to keep certain interval as the air expansion space, make through the air behind the previous stage filter and after expanding, enter the next stage filter again, thereby make the air stream that enters every grade of filter even, improve the filter efficiency of filter, the service life of prolongation filter.
Description of drawings
The structural representation of the modular filter device that Fig. 1 provides for the utility model embodiment;
The modular filter device that Fig. 2 provides for the utility model embodiment is applied in the schematic diagram in the fume cleaning equipment.
The specific embodiment
For ease of understanding, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment one
Present embodiment provides a kind of modular filter device, is used in the fume cleaning equipment, the flue gas after the air inlet pre-filtrating equipment pre-filtering in the fume cleaning equipment is carried out filtration, purification handle, and as shown in Figure 1, this modular filter device specifically comprises:
Framework 1, low efficient filter 2, medium effeciency filter 3, high efficiency particulate air filter 4 and active carbon filter 5;
Wherein, framework 1 is provided with a plurality of installation sites, and each installation site adapts with low efficient filter 2, medium effeciency filter 3, high efficiency particulate air filter 4 and active carbon filter 5 profiles respectively; Low efficient filter 2, medium effeciency filter 3, high efficiency particulate air filter 4 and active carbon filter 5 are successively set on each installation site of framework 1, install to be spaced apart 25~50mm as the gas expansion space between each filter of back.For preventing that being filtered gas enters the next stage filter from the interlayer gap, is provided with sealing gasket 6 and seals between the adjacent two layers filter of modular filter device.
In the combinations thereof formula filter, low efficient filter adopts synthetic fibers as filtering material, and filtering accuracy is 5 microns millimeters, and filter efficiency is 90%, and its effect is to filter the particle diameter that contains in the flue gas greater than 5 microns particle and coercibility material;
Medium effeciency filter adopts nonwoven and synthetic fibers, is made into the cloth-bag type structure, and filtering accuracy is 0.5 micron, filter efficiency 85%, and its effect is further to filter particle diameter less than 5 microns particles greater than 0.5 micron.Keep 25~50mm gap between low efficient filter and the medium effeciency filter as the gas expansion space;
