Abstract
The utility model discloses an environmental test cabin applied to the checkout of the content of poison material in architectural materials, mainly comprising a cabin body connected with a recirculating air system, an air cleaning treatment system, an air exchange wind system, an air humidity and temperature adjusting system, an electric appliance automation control system and an air sampling analysis system. The cabin body is provided with a test cabinet, a voltage equalizing cabin which is communicated with the test cabinet is arranged above the test cabinet, and a recirculating air chute which is connected with the test cabinet through the back aerofoil is arranged under the test cabinet. The recirculating air chute is communicated with the voltage equalizing cabin by the voltage equalizing partition board. The centrifugal fan accelerating air current circulating flow is arranged in the recirculating air chute. The voltage equalizing partition board between the voltage equalizing cabin and the test cabinet is provided with a honeycomb pipe which is arranged in length and breadth and is vertical to the voltage equalizing partition board, and the honeycomb pipe and is communicated with the voltage equalizing cabin and the test cabinet, ensuring that the air current entering the test cabinet uniformly runs forward. The current density or the temperature of the measured sample is ensured to be uniform in the test cabin, avoiding air current from forming vortex in the cabin, the error of the test data is decreased, the repeatability is good, and homogeneous flow of the air current can be ensured.
Description
(1) technical field:
The utility model relates to a kind of proving installation, relates in particular to a kind of environmental test chamber that noxious material volatile quantities such as contained formaldehyde of building materials and VOC are detected.
(2) technical background:
Along with the raising of expanding economy and national life level, huge variation has taken place in human room and working environment.Building decoration artificial board and goods thereof are widely used, and contain at present poisonous and harmful substance in China's artificial board mostly, contain a large amount of formaldehyde especially.Because of its formaldehyde emission has long process, after it was made furniture or is used for finishing, the formaldehyde in the sheet material still can constantly outwards distribute, and causes room air pollution, thereby the healthy of people worked the mischief.Thereby there is strict requirement in government department to contained formaldehyde amount in the artificial building board, the device that can develop contained formaldehyde amount in the artificial building board of accurate measurement has become the task of top priority, the applicant has developed this kind proving installation in 2000, and declared patent, patent name is " indoor environment testing cabinet for building engineering and combined type are surveyed the formula cabin ", and its number of patent application is 02115731.6.Find through repeated detection is on probation, directly enter in the test chamber after the equal ballasting in air enters environmental test chamber by equal plate hole, this kind intake method is easy to cause following deficiency: promptly in a single day air-flow enters test chamber content malleable direction, thereby air-flow can not evenly move forward in test chamber, make in the test chamber atmospheric density or sample non-uniform temperature or in the cabin, form eddy current, and then influence test data, make that the test data error is big, poor repeatability.
(3) summary of the invention: the test data error that exists when in order to solve environmental test chamber the building materials objectionable impurities being tested is big, the shortcoming of poor repeatability, and the utility model provides a kind of test data good reproducibility, error little, environmental test chamber accurately.
The technical solution of the utility model realizes in the following manner: a kind of environmental test chamber that is used for building materials noxious material content measuring, it mainly comprises and wind circulating system, the pure air disposal system, air changes wind system, the aerial temperature and humidity regulating system, the cabin body of electrical automation control system and air sampling analytic system, be provided with test cabinet in the body of cabin, wherein the test cabinet top is the equal ballasting that is communicated with test cabinet, the below is the circulation air path that is communicated with test cabinet by the return air plate, circulation air path communicates with equal ballasting by all pressing dividing plate, the centrifugal blower that promotes that air-flow circulates is housed in circulation air path, all between ballasting and the test cabinet all press dividing plate to be provided with to arrange in length and breadth with all press divider upright, the mozzle that communicates with equal ballasting and test cabinet is to guarantee to enter the evenly operation forward of air-flow in the test cabinet.
Circulation air path is by operating room's one side.
Centrifugal blower is axial flow blower and is located at the circulation air path turning.
Good effect of the present utility model is: because the setting of mozzle, make circulating current at first put in order to become parallel vertical, evenly move air-flow forward by mozzle, guarantee that test job indoor current density or sample temperature are even, avoid air-flow in the cabin, to form eddy current, make that the test data error is little, good reproducibility, the setting of axial fan and circulation air path further guarantee evenly flowing of air-flow.
(4), description of drawings:
Fig. 1 is the structural principle synoptic diagram of the utility model test chamber.
(5) embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As seen from Figure 1, the utility model mainly comprises and wind circulating system, the pure air disposal system, air changes wind system, the aerial temperature and humidity regulating system, the cabin body that electrical automation control system and air sampling analytic system connect, be provided with test cabinet 3 in the body of cabin, its test cabinet 3 tops are the equal ballasting 6 that is communicated with test cabinet 3, the below is the circulation air path 7 that the plate hole by return air orifice plate 2 is communicated with test cabinet 3, circulation air path communicates with equal ballasting 6 by test cabinet one side, the centrifugal blower 1 that promotes that air-flow circulates is housed in circulation air path 7, and all ballasting is provided with arrange in length and breadth vertical with equal pressing plate with the dividing plate of all pressing between the test cabinet, the mozzle 5 that communicates with equal ballasting 6 and test cabinet is to guarantee the evenly operation forward of test indoor air flow; Centrifugal blower 1 is for axial flow blower and be located at the circulation air path turning.
When this test chamber is worked, the air of coming in by the air dilution air plant that is communicated with circulation air path is under the effect of centrifugal blower, air walks to equal ballasting by circulation air path, form air-flow stably then, by the mozzle effect, it is indoor that the entering of vertical parallel placed estimating of specimen, when air-flow walks to the test cabinet bottom, by the return air orifice plate, suck the air channel once more by centrifugal blower.
After the air-flow in the operating room circulates the regular hour, take a sample, utilize pick-up unit to detect its content of formaldehyde by the air outlet that is communicated with circulation air path
This environmental test chamber is tested the formaldehyde volatile quantity of artificial board, and the situation that its result and sheet material are actual when using is coincide; Test result is with a high credibility; Being fit to the formaldehyde volatilization test of various materials, can be sheet material, goods and carpet, also can be the furniture of the whole series or the combined test of various materials; What this environmental test chamber was measured is the burst size of free formaldehyde, can provide the time course of sheet material release formaldehyde, and data approach the actual conditions of covil construction indoor environment, and the environmental test chamber method is being represented the development trend of artificial board burst size of methanal test.
