Description
Technical field
The utility model is related to a kind of harmful substance release amount detecting device, particularly a kind of to be used to detect that passenger car is in-car
The detection device of air and furniture harmful substance burst size.
Background technology
With the raising of automobile popularity rate, the harm that in-car harmful substance VOC etc. is caused to human body is increasingly by people institute
Pay attention to, country is also formulating related examination criteria and detection device.It is directed in in-car voc detection, standard and uses vehicle
Environmental chamber is detected, but is due to that the detection device floor space is big, high energy consumption, equipment use is more single, causes equipment
Vacancy rate is higher.Furniture detection is domestic at present also actively to carry out whole detection, it is also desirable to the larger environmental chamber of volume, related
The technical parameter of examination criteria, detection method is in close proximity to in-car voc detections, therefore, how that furniture detection and in-car is empty
Gas quality detection apparatus is effectively combined, to reduce equipment overlapping investment, and improving utilization rate of equipment and installations turns into the research topic of the present invention.
Vehicle detection device of the prior art mainly includes environmental test chamber and temperature and humidity control device, such as publication number
Disclose a kind of vehicle complete vehicle/sheet material environmental test chamber for CN104516368A Chinese patent, its mainly include experiment nacelle,
At least one set of aeration device being connected with experiment nacelle, it is controlled by the way of dew point is dehumidified and ultrasonic humidifier is humidified
It is wet.It needs to open the aeration device of respective numbers according to test, can meet difference by using the aeration device of multigroup setting
Different resh air requirements requirement under experiment condition.
The volume of environmental test chamber is not required in vehicle detection, vehicle to be measured test chamber can be opened, typically
Hold capacity is 200m3More than.And the volume of environmental chamber is required in furniture test, according to the surface area of furniture to be measured and cabin
The ratio between inner volume is optimal 0.3, and general furniture detection climate compartment volume of compartment is 5-16m3.Therefore, can to improve utilization rate of equipment and installations
VOC detection platforms are constituted so that the test chamber of one or several furniture detections is nested into vehicle detection environmental chamber, in theory
The temperature and humidity regulation of the test chamber of nested furniture detection can detect the temp and humidity regulator of environmental chamber using former vehicle,
But it is due to that nacelle volume after nesting is non-constant, after the relevant parameter that the wet device of dry and wet air control is regulated under large volume, when
Relative humidity is likely to result in when the test chamber of small size is used and fluctuates situation that is larger or even being unable to reach relative humidity, and
Can not be realized during use the test chamber of small size is individually controlled it is wet, it is impossible to meet use requirement.Also, at present, VOC
Temperature and humidity in environmental test chamber is mainly gathered by Temperature Humidity Sensor, and carrying out related humiture by controller adjusts
Section, sensor is generally all to be connected by wire with controller, and is had in the wire rod of sensor containing materials such as toluene, benzene
The voc such as toluene, benzene discharge, and it can influence the voc in test chamber to discharge testing result, therefore, the need for meeting voc tests,
Existing solution is that the threading mode for sealing the wire rod of sensor by stainless steel pipes carries out encapsulation process, is handled non-
It is often cumbersome, and reliability is poor, and such a mode is needed to plan and design in advance, and increase is needed after equipment installation
During sensor, then need to carry out cable tubing dismounting again, re-start cabling or threading operation, it is very inconvenient, very
The requirement for newly increasing sensor can not extremely be met.Further, since the VMC in furniture required by formaldehyde and voc detection must
It must be run in the case of certain pressure and flow, particularly pressure must be controlled in certain scope under low discharge
(need<1Kpa), prevent from causing follow-up filtration system too big pressure, damage filtering material, and the detection of existing vehicle is set
Standby its flow control accuracy under low voltage situations can not meet the requirement of furniture detection.Secondly, existing environment measuring equipment institute
The VOC of use adsorption filtration is carried out mainly by activated carbon, typically all purifies air inlet using ature of coal column-shaped active carbon, it is deposited
In many defects：Column-shaped active carbon is stacked excessively in treating column, windage can be caused excessive, it is impossible to reach the effect of purification, such as
Fruit stacks very few, then clean-up effect is just unable to reach testing standard, and after charcoal absorption reaches maximum, changes non-
It is often troublesome.
