Abstract
The mist collecting filtering element features that it includes filtering tip and filtering body, which has front cap and back cap with central vent hole at its two ends and stainless steel wire inside it. It can collect mist sample and thus provide one effective measure for quantitative analysis of mist. It has high adsorption efficiency for mist and is easy to clean.
Description
The utility model relates to a kind of mist collecting device that is used for environmental monitoring.
The oil smoke mist is the environmental pollution gas that a kind of kitchen or food processing factory produce.Because it has the characteristic of viscosity than big and complicated component, be difficult under normal conditions gathering and analyzing, up to the present also there is not the harvester of this oil smoke mist to appear on the market, makes that in environmental monitoring and environmental analysis field, the quantitative analysis of oil smoke gas pollutant is a universally recognized difficult problem always.
The purpose of this utility model is: a kind of mist collecting filtering element is provided, can highly effective gathering oil smoke mist sample, for the accurate quantitative analysis of oil smoke mist provides effective means.This filter core also cleans easily to the adsorption efficiency height of oil smoke mist.
The technical solution of the utility model is: a kind of mist collecting filtering element, it is characterized in that: comprise filter tip and filter body, (being the filter body end) is provided with the filter body protecgulum between described filter tip and filter body, is provided with the filter body bonnet at the afterbody of filter body, is provided with wire in the filter body the inside; The middle part of described filter body protecgulum and bonnet is equipped with passage.
Afterbody at aforesaid mist collecting filtering element connects devices such as breather pipe, gas flowmeter and air pump, under the air pump effect, oil smoke gas to be taken a sample enters in the filter body from filter tip, the contained oil content overwhelming majority is attracted on the interior wire of filter body in the oil smoke gas, the gas that passes filter body continues operation forward along breather pipe, and is quantitative through gas flowmeter.After going out adsorbed oil content quantity by the physical method wash-out and with infrared spectrophotometric determination, can calculate the accurate content of oil smoke mist in the oil smoke gas very easily.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the overall structure schematic diagram of an exemplary embodiments of the utility model mist collecting filtering element.
The utility model mist collecting filtering element as shown in Figure 1, comprise filter tip 1 and filter body 4, (being the filter body end) is provided with filter body protecgulum 2 between filter tip 1 and filter body 4, is provided with filter body bonnet 6 at the afterbody of filter body 4, is provided with wire 8 in filter body 4 the insides; The middle part of filter body protecgulum 2 and bonnet 6 is equipped with passage 11.The effect that is located at the wire 8 in the filter body 4 is an adsorbed oil smog, and test shows that wire has advantages of good adsorption effect as the oil smoke adsorbate, cleans advantage especially easily simultaneously.
The present embodiment filter core also is provided with filter core cover 5 and is fastened on the filter core cover end cap 3 that filter core overlaps 5 heads; Filter body 4 and protecgulum 2 thereof, bonnet 6 all place filter core cover 5 and the formed space of filter core cover end cap 3 button boxes.
Present embodiment is peripherally equipped with heating wire 9 filter core cover 5, is provided with outer sleeve 10 in the outside of heating wire 9 heating wire 9 is covered.Heating wire can heat filter core, if mix temperature control device, can realize temperature control absorption.
Hole 12 is established at the middle part of filter core cover end cap 3, and the back segment of filter tip 1 passes this hole 12 and connects with filter body protecgulum 2.1 location of the 12 pairs of filter tips in hole and fixation.During sampling, because oil smoke smoke pipe air-flow has different in flow rate with different blower fans,, must change the air inlet bore of filter tip according to circumstances, but in order to suit with filter core cover end cap 3 and filter body protecgulum 2, outer shape and size should guarantee constant for guaranteeing the isokinetic sampling.Explanation is just used in the time of can processing identical and the filter tip that internal diameter is different of some external dimensions in order to different occasion in advance.Present embodiment filter tip 1 cooperates with end cap 3 this plug-in types can fully satisfy above-mentioned requirements.
The utility model filter core is provided with ventilation base 13 at the afterbody of filter core cover 5, and breather pipe 7 is used to peg graft.
In the present embodiment, port of export outer rim one band of filter tip 1 is designed to arc surface 14, and middle part, filter body protecgulum 2 outer ends is tubaeform scrobicula 15.Arc surface 14 cooperates with the perisporium of scrobicula 15, realizes positiver sealing between the two.
In the present embodiment, the internal diameter entrance of filter body 4 is big, the little and flare transition of outlet section, and the exit internal diameter is corresponding with the distribution of the passage 11 of filter body bonnet 6.The entrance internal diameter is big, and it is unimpeded to help air inlet, makes full use of the wire detention oil smoke mist of each several part; Little and the flare of outlet section carries out the transition to the same big with the scope of bonnet upper vent hole, helps cleaning, and the cleaning fluid that can not form resemble the square is detained the dead angle.
In the present embodiment, the airway 16 on filter tip 1 axis is designed to cylindrical, and cylindrical airway is compared with tubaeform airway, can reduce the aerocolloidal absorption detention of viscosity in the oil smoke mist.
Wire 8 can be stainless steel wire, also can be other wire, is shaped as the pancake long filament, and its width and gauge can be with reference to following design data: wide is 0.40 ± 0.08mm, and thick is 0.10 ± 0.02mm, and length is not limit.Design like this can fully increase surperficial adsorption area on the one hand, makes aeration resistance suitable on the other hand.To width and the suitable error range of thickness regulation, can guarantee that adsorbed oil smog has better reappearance.
