Along with furniture industry is flourish, the market comsupton share constantly increases, yet VOCs such as the formaldehyde that discharges in wooden furniture and the decorating and renovating material, VOC are the main sources of indoor environment environmental pollution, in furniture consumption, can not be ignored.In recent years, increasing people comes to realise indoor environment to health affected.Room air pollution has become the third-largest pollution that is only second to coal-smoke pollution and petrochemical complex pollution, day by day seriously healthy the and existence of harm humans.The domestic environment that has a safety and Health becomes the focus of public attention.
Poisonous and harmful volatile matter burst size is the most scientific and effective detection means in the present detection method in employing environmental test chamber method test furniture, artificial board, the building materials article; Both at home and abroad with the referee method of environmental test chamber method as measurement and evaluation building and ornament materials and indoor article organic contaminant burst size; Its principle of work is following: test chamber is interior behind dry decontamination; Under the certain load ratio of test chamber spatial volume (surface area of test specimen with) condition; Temperature, humidity, air velocity and air exchange rate (per hour getting into the pure air volume of test chamber and the ratio of test chamber spatial volume) in the adjustment cabin; Test specimen is put in the test chamber, and makes air draught equably from test specimen surface current mistake.After the certain time, gather air sample in a certain amount of cabin, content of harmful such as formaldehyde, VOC in the sample in the test air, thereby the Environmental Safety performance of confirming to test test specimen.
Domestic research for little volume environment test chamber (< 5m3) is basic forming, and is widely used in to detect and puts into practice in the work.But still there is not approved product at present for big volume environment test chamber (requiring minimum 22m3 among the ASTM E1333) is domestic; Though many scientific research institutions and enterprise are arranged to be studied big volume environment test chamber; But wherein still have weak point: require to make the interior air draught of test chamber in the method for testing standard equably from test specimen surface current mistake; Air velocity scope 0.1m/>s～0.3m/s in the test chamber; And at present domestic existing big volume environment test chamber adopts the mode that fan or one-sided installation air channel are installed in the cabin to design, and is difficult in the assurance cabin homogeneity of air velocity everywhere, therefore; The representativeness of gathering air sample in the cabin is not quite reasonable, and it detects data and makes us querying.
Summary of the invention
The purpose of the utility model is to provide a kind of big volume environment test chamber recirculating air device; A kind of structural design to big volume environment test chamber recirculating air device has been proposed; This structural design has been guaranteed the equilibrium of testing environment wind speed field; Solved the mensuration of large environment test chamber, scientific and effective calibrating is provided volatile poisonous and harmful substance burst size in furniture group and the building materials.
The purpose of the utility model realizes through following technical scheme:
Big volume environment test chamber recirculating air device; Comprise return air cover, circulation air path, return air dividing plate, all press chamber and return air plate, the top of test chamber inner room is provided with top, cabin return air dividing plate, and the bottom of top, cabin return air dividing plate is equiped with all presses the chamber; Test chamber inner room and top, cabin return air dividing plate are separated; The both sides, bottom of test chamber inner room are equiped with centrifugal blower, the bottom, air port of centrifugal blower, and the air outlet that is provided with return air cover, centrifugal blower is relatively on circulation air path; The staggered vertical both sides that are installed on environmental test chamber of a plurality of circulation air paths; Communicates with circulation air path and centrifugal blower in the test chamber, and communicate with return air cover and circulation air path, the return air dividing plate is connected with equal chambers of pressure through the top, cabin again; After the return air plate communicates with the test chamber inner room again, be circulation shape passage.
Described big volume environment test chamber recirculating air device has aperture on the return air plate of its said even pressure chamber.
The advantage and the effect of the utility model are:
The positive role of the utility model is: guaranteed the equilibrium of big volume environment test chamber to poisonous and harmful volatile substances amount testing environment wind speed field in the test test specimens such as furniture group, ornament materials, building materials; Therefore; The simulation test that makes it is science, rationally more, and test data is more reliable truly.
