Abstract
The utility model relates to a gas sampling device, in particular to a sampling head for organic pollutant. The sampling head for the organic pollutant comprises a funnel-shaped collecting cover, a filter membrane, a pressed film cover which is used for pressing the filter membrane on the mouth portion of the collecting cover and a connecting pipe which is connected with an air pump. The sampling head for the organic pollutant is characterized by further comprising a filter material barrel. One end of the filter material barrel is connected with the collecting cover, the other end of the filter material barrel is connected with the connecting pipe, and polyurethane foam is arranged in the filter material barrel. The sampling head for the organic pollutant has the advantages of being reasonable in design, convenient to use, wide in application range and capable of collecting particulate matter and volatile organic pollutant and semi-volatile organic pollutant simultaneously or alone.
Description
Technical field
The utility model relates to a kind of sampler of gas, especially a kind of organic contaminant sampling head.
Background technology
We know, Atmospheric particulates content is a whether important symbol up to standard of a plant produced discharging.And in modern industrialization is produced, in the waste gas that a lot of factory and enterprises are discharged, not only contain particle, also contain volatility and half volatile pollutant, such as organic contaminants such as palycyclic aromatic, benzene homologues, petroleum hydrocarbons, and these organic contaminants are often larger to human body and environmental hazard.Therefore, on the basis of carrying out the Atmospheric particulates content detection, detecting simultaneously these volatility and half volatile organic contaminant also becomes one of index of estimating atmosphere quality.At present, the atmosphere organic pollutant sampler that uses reaches the sampling head that is communicated with it by aspiration pump and forms, has the different pore size filter membrane in its sampling head, being used for collecting the atmosphere suspended particle gathers, when gathering Atmospheric particulates, although the particle that is attached on the filter membrane has also adsorbed sub-fraction volatility and half volatile organic contaminant, but the organic contaminant of most of volatility and half volatile but passes through filter membrane together along with granule, has caused the organic contaminant of volatility and half volatileness not detected by effective the collection.
Summary of the invention
Can not effectively gather the deficiency of volatility and half volatile organic contaminant in order to overcome sampling head in the prior art, the utility model provide a kind of reasonable in design, easy to use, and can be simultaneously or the organic contaminant sampling head that separately particle and volatilization and half volatile organic contaminant gathered.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of organic contaminant sampling head, it comprises that a funnelform collection cover, a filter membrane, are fitted in the press mold lid of collection cover oral area and the adapter that connects aspiration pump of with filter membrane, it is characterized in that: it also comprises a filtrate cylinder, one end of this filtrate cylinder is connected with described collection cover, the other end is connected with described adapter, has added isocyanurate foam in filtrate cylinder inside.
The utility model has added isocyanurate foam owing to be pressed with filter membrane at collection cover oral area in the filtrate cylinder inside that is connected with the collection cover.When gas passes through sampling head, the sub-fraction volatilization or the half volatile organic contaminant that adsorb on particle in the atmosphere and the particle are captured by filter membrane, are captured by the isocyanurate foam in the filtrate cylinder and leak most of volatility and the half volatile organic contaminant filtered from filter membrane.Simultaneously, the utility model can not press-fit filter membrane gathering the cover oral area in the time need not gathering in the atmosphere particle, only needs add in the filtrate cylinder that isocyanurate foam is volatilized or the half volatile organic contaminant sampling; When only needing to gather in the atmosphere particle, only press-fit filter membrane gathering the cover oral area, need not add isocyanurate foam in the filtrate cylinder and get final product.Therefore, the utility model can be simultaneously or separately particle and volatilization and half volatile organic contaminant is gathered.Compared with prior art, the utlity model has advantage reasonable in design, easy to use, applied widely.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further.
Accompanying drawing is a kind of complete section structural representation of the present utility model.
Among the figure: 1. gather cover, 2. filter membrane, 3. press mold lid, 4. adapter, 5. filtrate cylinder, 6. isocyanurate foam.
Embodiment
In the accompanying drawings, a kind of organic contaminant sampling head, it comprises a funnelform collection cover 1, a filter membrane 2,3 and one adapter 4 of press mold lid.
As shown in drawings, press mold lid 3 and collection cover 1 thread connection are fitted in filter membrane 4 oral area that gathers cover 1.
Adapter 4 is provided with and connects mouth, utilizes this to connect mouth and connects aspiration pump.
In the accompanying drawings, a kind of organic contaminant sampling head also comprises a filtrate cylinder 5.
As shown in drawings, an end of filtrate cylinder 5 is connected with collection cover 1, and the other end is connected with adapter 4.Filtrate cylinder 5 of the present utility model can adopt with the connected mode that gathers cover 1, adapter 4 and be threaded, and also can adopt grafting, and be assembled into one.
In the accompanying drawings, added isocyanurate foam 6 in filtrate cylinder 5 inside.Isocyanurate foam 6 can effectively be adsorbed volatility and half volatile pollutant in the atmosphere as adsorbent, and such as palycyclic aromatic, benzene homologues, petroleum hydrocarbon etc., its adsorption rate reaches more than 90%.
During use, by the aspiration pump of running, atmosphere is discharged by the filter membrane 2 on the sampling head, isocyanurate foam 6.In said process, the sub-fraction volatilization or the half volatile organic contaminant that adsorb on particle in the atmosphere and the particle are captured by filter membrane 2, and the most of volatility and the half volatile organic contaminant that leak filter from filter membrane 2 are captured by isocyanurate foam 6, thereby have realized the collection to atmosphere organic pollutant.
When only needing to gather in the atmosphere particle, only press-fit filter membrane 2 gathering cover 1 oral area, need not add isocyanurate foam 6 in the filtrate cylinder 5 and get final product.
In the time need not gathering in the atmosphere particle, can not press-fit filter membrane 2 gathering cover 1 oral area, only need in filtrate cylinder 5, add that isocyanurate foam 6 is volatilized or the half volatile organic contaminant sampling.
The utility model is reasonable in design, easy to use, applied widely.
