Abstract
The utility model relates to a relative humidity controller of an organic material volatile substance releasing cabin, which is used for environment protection detection. A clean dry air source is respectively connected with the end A of a three-way valve and a humid air generator, the humid air generator is also connected with the end B of the three-way valve, the mixed dry air and humid air enters the releasing cabin through the end A and the end B of the three-way valve, a humidity sensor is arranged in the releasing cabin, the humidity sensor is connected with the humidity control meter, and the humidity control meter is also connected with a regulator of the three-way valve. The utility model has the advantages that when the relative humidity in the releasing cabin is greater or smaller than the set value, the humidity sensor can notify the humidity control meter for regulating the three-way valve and changing the flow ratio of the dry air and the humid air, so the relative humidity in the releasing cabin is maintained at the set value.
Description
Technical field
The utility model relates to the organic material volatile substance releasing cabin relative humidity control device that a kind of environmental protection tests is used.
Background technology
Along with the development and the continuous progress in science and technology of society, the application of organic material is more and more, and organic material in use usually can produce the volatility toxic gas, influences environment and health.
For character and the quantity that detects harmful gas in the volatile matter, detected material need be put in the experiment release cabin and carry out, mensuration process need in the release cabin is at constant temperature, constant humidity, permanent gaseous tension, permanent gas velocity, fix time and decide and carry out under the unified condition of gas flow, feed the pure air of certain flow as carrier from the one side of cabin body, then carrier gas and the exhausr port of the escaping gas potpourri that discharges from the another side of cabin body are entered in the wash bottle that fills aquae destillata, these escaping gases just are dissolved in the aquae destillata, analyze the composition in the aquae destillata, just can measure the character and the quantity of objectionable impurities, the data of Jian Ceing have comparability and reliability like this.
In the testing process, the weather conditions that discharge in the cabin all have certain specialized range, and especially airborne relative humidity control more has quite high requirement, generally should be controlled at ± 3% in, difficult realization.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of can make the relative humidity strictness remain on the interior volatile substance releasing cabin relative humidity control device of specialized range.
The utility model solves the problems of the technologies described above the technical scheme of being taked: a kind of volatile substance releasing cabin relative humidity control device, wherein, clean dry air source links to each other with soft air generator entrance point with the A end of three-way valve respectively, the soft air generator is connected with the B end of described three-way valve again, mixed dried soft air enters the release cabin by the AB end of described three-way valve, discharge in the cabin and be provided with humidity sensor, humidity sensor and humidity control table are joined, and the humidity control table is joined with the regulator of three-way valve again.
Advantage of the present utility model is:
When the relative humidity in discharging the cabin was greater than or less than setting value, humidity sensor will notify the humidity control table that three-way valve is regulated, and changed flow proportional dried, soft air, and the relative humidity that discharges in the cabin is remained in the setting value.
