The air supply purifying and drying device has simple structure, can satisfy the requirements through a plurality of procedures, and has low cost; the entire process is free from producing any harmful gas and free from polluting the air; the purified air can conform to the standardand can complete the detection normally; and with a flow-meter and an adjusting valve, the flow rate of the air can be instantly detected and controlled. The air supply purifying and drying device hashigh popularization and application value.
Description
Technical field
The utility model relates to a kind of gas source purification drying device, specifically is a kind of device that eudiometry is tested artificial board formaldehyde that is applied in.
Background technology
Follow China's rapid development of economy, wood-based panel industry has had develop rapidly, setting up as medium-sized and small enterprises are seemingly emerged rapidly in large numbersBamboo shoots after a spring rain.Several centralized production bases (about 7,000 families of scale enterprise) have appearred in the whole nation, and China's wood-based plate output was 4955.36 ten thousand steres in 2004, had become the first in the world wood-based plate big country.Wood-based plate has entered huge numbers of families, becomes one of most important material of decoration design for residence and furniture manufacturing.But the thing followed is because the release of the free formaldehyde of wood-based plate particularly exceeds standard release and room air is produced pollution, the health that is endangering people, thus more and more be subjected to people's attention.Therefore detection, the control to artificial board formaldehyde burst size is the strongest requirement at present.Also be pressing for of wood-based panel industry development itself.
Measure artificial board formaldehyde release several different methods is arranged.Wherein " perforation extraction ", " drier method " and " climate box method " have been put into national standard, formally publicize and implement.These three kinds of methods are used in different conditions and occasion, but all exist some problems.
" climate box method " method is simulated typical temperature, humidity and ventilation condition, approaches actual user mode most, and testing result also can reflect actual conditions, but needs large-scale checkout equipment, and sense cycle is the longest 28 days, detects the cost height.
What " perforation extraction " test obtained is the content of formaldehyde of test specimen, rather than the emission of formaldehyde.Plank in use can not all be come out all free formaldehydes by the condition effect such as temperature, relative humidity and ventilation condition of test specimen density, moisture content, place environment.In addition, the extraction solvent toluene that perforation method adopts itself contains toxic, and useless toluene can not at will disorderly fall, and also should not repeatedly distill multiplexingly, has caused many troubles to the user.Many again unfavorable to the protection environment.
" drier method " needs in 24 hours placement vessel, and the disturbing factor of existence is many, as ambient air quality, test specimen moisture content change, ambient temperature and humidity, the cleanings of drier inwall etc. easily influence the degree of accuracy of measurement result.
In view of above reason, new standard a: EN717-2:1995 " artificial board formaldehyde burst size mensuration---eudiometry is measured formaldehyde and discharged " has been put into effect in Europe.
Above-mentioned standard has very high requirement, air mass flow: 60 ± 3L/h, relative humidity to the content of various impurity in the source of the gas, the flow of source of the gas etc.:＜3%; Or the like.Realize above-mentioned standard, particularly important to the processing of source of the gas with regard to what show.
Summary of the invention
At above-mentioned problem, the utility model provides a kind of novel structure, effective, gas source purification drying device that cost is low relatively.
The gas source purification drying device that the utility model provides comprises the air-intake filter, air pump, Drexel bottle, drier and the pneumatic filter that connect successively, and above-mentioned each device is set at least one respectively.
Between above-mentioned drier and pneumatic filter, also be provided with at least one gas flowmeter.
Between above-mentioned drier and gas flowmeter, also be provided with gas control valve.
Preferably, above-mentioned each device is set to one, promptly is connected with air-intake filter, air pump, Drexel bottle, drier, gas control valve, gas flowmeter and pneumatic filter in turn.
Wherein, the air inlet roughing efficiency air filter carries out primarily efficient filter to air, filters out impurity such as airborne dust, particle, and air pump provides power, make air-flow enter this device, Drexel bottle is carried out water filtration to air, and then carries out drying by drier, and gas control valve can be regulated the air-flow size, gas flowmeter detects the air-flow size and shows, active carbon filter is finished last filtration, filters out the foreign gas except that formaldehyde, and output contains the gas of a certain amount of formaldehyde.
The gas source purification drying device that the utility model provides, simple in structure, can reach requirement through after some steps, cost is very cheap; In whole process, do not produce any pernicious gas etc., can contaminated air; Through the air that purification and can meet standard, can normally finish detection; Be provided with flowmeter and control valve, the flow of detection that can be real-time and control gas.In a word, this device has very big application value.
Description of drawings
Fig. 1 is the structure principle chart of the utility model embodiment.
Wherein, 1. roughing efficiency air filter, 2. air pump, 3. Drexel bottle, 4. drier, 5. gas control valve, 6. gas flowmeter, 7. active carbon filter.
The specific embodiment
Further explain, illustrate the technical program with non-limiting embodiment below.
A kind of gas source purification drying device comprises the roughing efficiency air filter 1, air pump 2, Drexel bottle 3, drier 4, gas control valve 5, gas flowmeter 6 and the active carbon filter 7 that connect successively, and each device all is 1.
Like this, air successively passes through said apparatus, carry out primarily efficient filter at air inlet roughing efficiency air filter 1, impurity such as the dust in the filtered air, particle, air pump 2 provides power then, in Drexel bottle 3, carry out water filtration, enter again and carry out the drying processing in the drier 4, can detect it during air-flow process gas flowmeter 6, through last active carbon filter 7, cross filtering formaldehyde foreign gas in addition, finish whole process.
Claims (3)
1. gas source purification drying device is characterized in that: comprise the roughing efficiency air filter (1), air pump (2), Drexel bottle (3), drier (4) and the active carbon filter (7) that connect successively, above-mentioned each device is set at least one respectively.
