The beneficial effects of the utility model are that, operation with low costs, easy, purifying effect is good, and the resistance is little. Can regard as the preceding processing apparatus of a novel purge gas. It piles up filtration method or other difficult method or devices that uses to replace current active carbon.
Description
Technical field
The invention belongs in gas detect the field needed gas particular purification demand, relate to a kind of detection gas purifier, mainly for the purification of volatile contaminant.
Background technology
When carrying out the detection of VOC (VOCs), clean gas can be used, this clean gas is mainly used in the formulation of such as calibration curve, clean nitrogen is utilized to rush the process of adsorption tube, especially when needs control gas flow, gas needs, through flowmeter, pressure-reducing valve, rubber tube etc., gas can be allowed to be subject to the pollution of pipeline, and affect the accuracy of testing result.
At present, still there is no equipment for this pollution condition, but in analytical chemistry, by utilizing the mode of filtering flask, gas is led to as the gas cylinder with active carbon carries out filtration, purification to gas.But after being through filtering flask, gas is owing to being subject to the resistance of active carbon on the one hand, and flow can be affected; Secondly because gas is only disposable through active carbon, filter efficiency is lower.
Summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides that a kind of structure is simple, easy to use, the detection gas purifier of good purification.
The present invention is achieved through the following technical solutions:
Detection gas purifier of the present invention, it is characterized in that: it is overall is all-sealed structure, comprise casing, casing is provided with air inlet and gas outlet, box house is provided with some layers of filtering grid, interior space is become multiple little space, every layer of grid is placed with the adsorbent bag that one deck plays filtration, purification effect.
Filtering grid comprises dividing plate and crossbeam, and dividing plate is arranged on box house, has cut-out in the middle part of dividing plate, and crossbeam to be arranged on below dividing plate and corresponding with cut-out, crossbeam is placed adsorbent bag, is provided with a circle sealing gasket between dividing plate and adsorbent bag.
Filtering grid is also provided with gas overflowing hole.
Filtering grid adopt drawer-type structure, can pull be arranged in casing, for convenience detach, the openings contact place of filtering grid side and casing is also provided with sealing gasket.
Dividing plate and crossbeam are made up of stainless steel.
Adsorbent bag adopts active carbon bag.
Sealing gasket adopts polytetrafluoroethylene (PTFE) pad.
Box house establishes the filtering grid that haves three layers, and interior space is become 4 little spaces.
The end of the drawer-type structure of filtering grid is provided with handle.
This product is through multi-filtering grid, and loose for active carbon keeping flat can be mated formation, overflow setting simultaneously, effectively reduce resistance, adopt Multi-layer design simultaneously, through repeatedly purifying, purification efficiency is higher.Sealing strip polytetrafluoroethylene (PTFE) material, avoids the pollution of encapsulant to gas, and adopt drawer type design, the active carbon after being easy to use changes the outfit simultaneously.
The invention has the beneficial effects as follows, cost is low, easy to operate, good purification, and resistance is little.Can as a kind of pretreating device of new type purification gas.Substitute existing active carbon and pile up filtration method or other not wield method or device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 is sealing gasket, and 2 is handle, and 3 is gas overflowing hole, and 4 is adsorbent bag, and 5 is dividing plate, and 6 is crossbeam, and 7 is air inlet, and 8 is gas outlet, and 9 is casing.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.
Detection gas purifier of the present invention, its entirety is all-sealed structure, comprises casing 9, casing is provided with air inlet 7 and gas outlet 8, box house is provided with some layers of filtering grid, interior space is become multiple little space, and every layer of grid is placed with the adsorbent bag 4 that one deck plays filtration, purification effect.
Filtering grid comprises dividing plate 5 and crossbeam 6, and dividing plate is arranged on box house, has cut-out in the middle part of dividing plate, and crossbeam to be arranged on below dividing plate and corresponding with cut-out, crossbeam is placed adsorbent bag, is provided with a circle sealing gasket 1 between dividing plate and adsorbent bag.
Filtering grid is also provided with gas overflowing hole 3.
Filtering grid adopt drawer-type structure, can pull be arranged in casing, for convenience detach, the openings contact place of filtering grid side and casing is also provided with sealing gasket 1.
Dividing plate and crossbeam are made up of stainless steel.
Adsorbent bag adopts active carbon bag.
Sealing gasket adopts polytetrafluoroethylene (PTFE) pad.
The end of the drawer-type structure of filtering grid is provided with handle 2.
This Total Product is stainless steel, and size can adjust as required, this suggestion be of a size of the wide * of long * high=200mm*100mm*200mm divides four layers, specific design is shown in accompanying drawing.Have three layers in this device dividing plate, and every layer is divided into two parts, and Part I is filtration fraction, and Part II is for overflowing part.Part I is divided into stainless steel separator, stainless steel crossbeam and polytetrafluoroethylene sealing gasket, crossbeam is cylindrical diameter is 3mm, be placed in below dividing plate, hollow out in the middle of dividing plate, surrounding is the sealing gasket of polytetrafluoroethylene (PTFE), Part II is corrosion resistant plate, only establishes a hole, and this bore dia is 3mm is gas overflowing hole.This equipment entirety sealing, inlet, outlet is used time rubber tube and iron clamp sealing not, to ensure the activity of active carbon.Active carbon should according to the concentration of filtering gas and filtration time, and after filtering, gas TVOC concentration is more than 0.05mg/m
3in time, should be changed immediately.
In accompanying drawing, 1 is the sealing gasket of polytetrafluoroethylene (PTFE) material without release and absorption, is separately positioned on end and the Part I dividing plate surrounding of drawer, seals.2 is handle, can pull drawer easily when changing active carbon.3 is gas gas overfolw hole.4 is active carbon bag, is positioned on Part I, and this active carbon bag size should be measure-alike with Part I, and 5 is dividing plate, and hollow out in the middle of dividing plate, surrounding stays limit, hollows out size fixed with active carbon bag size, and the design's suggestion is 100mm*50mm.6 is stainless steel crossbeam, is arranged on below dividing plate, and diameter is 3mm, plays and supports the effect of active carbon bag.
Need the gas of purification by mouth 7 access arrangement, through the packet filtering of ground floor active carbon, if throughput is large, excessive gas is spilled over to the second layer through the gas overflowing mouth 3 of ground floor.
Enter the gas of the second layer through second layer activated carbon filtration, unnecessary gas is overflowed by the overfall of the second layer.By that analogy to the 4th layer, discharge the gas after filtration by gas outlet 8.
