The silica gel in the first-grade filter cylinder is macroporous silica gel, and the silica gel in the second-grade filter cylinder is fine-pored silica gel. The volume of the sponge cushion in the first-grade filter cylinder is 1/3-2/3 of the volume of the first-grade filter cylinder. The second-grade filter cylinder is a rotator with the coarse middle part and two fine ends. The filtering apparatus is externally used, and is installed at the air inlet of the CD4 multi-parameter gas detector, realizes the effect of thoroughly filtering dust and water, is capable of solving the problem pointed out in the background technology, and is good in usage effect.
Description
Technical field
The present invention relates to a kind of filtration unit, particularly relate to a kind of gas sampler filtration unit.
Background technology
The CD4 Multi-parameter gas detector environment for use condition that current shaft production uses is humidity≤98%RH, and some long-term humidity in a big chunk region, down-hole reaches 100%RH, especially moist with summer.In actual use, detector only has one deck filter membrane can play the effect of Chalk-dust filtering, moisture content, and filter effect is poor, metrical error is large to cause instrument often to occur, serviceable life is short, and even directly the generation of the situation such as blank screen, deadlock, causes very large impact to mine safety.

The object of this invention is to provide a kind of gas sampler filtration unit of good filtration effect.
For achieving the above object, the technical solution used in the present invention is:
A kind of gas sampler filtration unit, it is characterized in that, comprise the single filter cylinder and cascade filtration cylinder that are connected by gas line, all silica gel is filled with in single filter cylinder and cascade filtration cylinder, in single filter cylinder, rear portion is divided into silica gel, forward part is filled with foam-rubber cushion, the inlet end of single filter cylinder is also connected with dust filter membrane, and the endpiece of cascade filtration cylinder is communicated with bulbs,double, and bulbs,double is communicated with can survey with CD4 Multi-parameter gas detector the card cap be connected.
According to described gas sampler filtration unit, it is characterized in that, the silica gel in described single filter cylinder is macro porous silica gel, and the silica gel in described cascade filtration cylinder is Kiselgel A.
According to described gas sampler filtration unit, it is characterized in that, in described single filter cylinder, the volume of foam-rubber cushion is 1/3 to 2/3 of single filter cylinder volume.
According to described gas sampler filtration unit, it is characterized in that, described cascade filtration cylinder is the rotary body that centre is thick, two ends are thin.
The present invention is a set of external filtration unit, this device is installed on the air intake opening of CD4 Multi-parameter gas detector, by foam-rubber cushion Chalk-dust filtering, by filtered through silica gel moisture content, tested gas is after foam-rubber cushion and silica gel, again through bulbs,double press-in CD4 Multi-parameter gas detector, achieve the effect of thorough Chalk-dust filtering, moisture content, can solve the problem that background technology is pointed out, result of use is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In accompanying drawing:
1, dust filter membrane; 2, foam-rubber cushion; 3, single filter cylinder; 4, macro porous silica gel; 5, gas line; 6, cascade filtration cylinder; 7, Kiselgel A; 8, bulbs,double; 9, card cap.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
A kind of gas sampler filtration unit, as shown in Figure 1, comprise the single filter cylinder 3 and cascade filtration cylinder 6 that are connected by gas line 5, all silica gel is filled with in single filter cylinder 3 and cascade filtration cylinder 6, in single filter cylinder 3, rear portion is divided into silica gel, forward part is filled with foam-rubber cushion 2, the inlet end of single filter cylinder 3 is also connected with dust filter membrane 1, and the endpiece of cascade filtration cylinder 6 is communicated with bulbs,double 8, and bulbs,double 8 is communicated with can survey with CD4 Multi-parameter gas detector the card cap 9 be connected.
Silica gel in described single filter cylinder 3 is macro porous silica gel 4, and the silica gel in described cascade filtration cylinder 6 is Kiselgel A 7.In described single filter cylinder 3, the volume of foam-rubber cushion 2 is 1/3 to 2/3 of single filter cylinder 3 volume.Described cascade filtration cylinder 6 is the rotary body that centre is thick, two ends are thin.
Original one deck filtering membrane on CD4 Multi-parameter gas detector sampling pump, this layer of filtering membrane Main Function is the impurity such as the dust in filtering tested gas, also there is the effect of certain filtration moisture content simultaneously, but moisture content and dust-filtering effect are also not obvious, cause having part moisture content and dust to enter instrument when using, affect accuracy of detection and the serviceable life of instrument, logical anti-safety is affected.
The present invention is a set of external filtration manifold set up on the basis of original CD4 Multi-parameter gas detector, can Chalk-dust filtering and moisture content, is applicable to band sampling pump and two kinds of detectors not with sampling pump.When use carries the CD4 Multi-parameter gas detector mensurated gas composition of sampling pump, do not use bulbs,double and card cap, when using general CD4 Multi-parameter gas detector mensurated gas composition, using bulbs,double to bleed, realizing the effect of multifunctional filtering.
The present invention is made up of filtration fraction and air-breathing part two parts, filtration fraction comprises the cylindrical plastic conduit of two both ends opens as cartridge filter, load silica gel in plastic tube and (nontoxic, odorless, there is larger internal surface area, to water vapour and other condensable steam, there is higher adsorptive power), realize the function of cascade filtration moisture content, in single filter cylinder, place foam-rubber cushion in addition, realize the effect of Chalk-dust filtering; Air-breathing part utilizes bulbs,double air-breathing, is connected by the air intake opening of the air entry of bulbs,double with CD4 Multi-parameter gas detector by card cap, and tested gas just can suck in article by extruding spheroid, so repeatedly.
The present invention uses silica gel as absorbent material, and silica gel is a kind of high activity sorbing material, belongs to amorphous substance, its chemical molecular formula is mSiO2nH2O, water insoluble and any solvent, nonpoisonous and tasteless, stable chemical nature, does not react with any material except highly basic, hydrofluorite.The silica gel of various model forms different microcellular structures because its manufacture method is different, the chemical composition of silica gel and physical arrangement determine it to be had other same type of material many and is difficult to replace to obtain feature, as high in absorption property, Heat stability is good, stable chemical nature, has higher physical strength etc.Silica gel is divided into macro porous silica gel, silochrom, Type B silica gel, Kiselgel A according to the size in its aperture.This filtration unit adopts Kiselgel A, Kiselgel A is colourless or yellowish transparent or semitransparent type particle, there are many minute apertures inside, surface area reaches 700 meters squared per gram, when its absorption moisture reaches capacity state, the change of surface and form can not be there is, there is the features such as moisture absorption is fast, indeformable.
After using device of the present invention, the degree of accuracy that CD4 Multi-parameter gas detector measures significantly improves, and serviceable life was increased to 3 years by original one year, and the situation such as blank screen, deadlock almost seldom occurs, played a significant role logical anti-safety.
