Description
Technical field
The present invention relates to a kind of psychrometry standard devices, wet more particularly to a kind of dual-temperature process standard that low dew point occurs
Generator is spent, metrological testing technology field is belonged to.
Background technique
Humidity generator is widely used measuring equipment during calibrating or calibration moisture instruments.It is wet for standard
Generator is spent, wherein moisture-saturated device is the critical component in humidity generator, usually using thermally conductive good metal material system
It is connected in series at moisture-saturated device, and using multistage moisture-saturated device.It is exactly that oversaturated gas is passed through humidity that it, which is acted on,
Saturator reaches the steam-laden at a certain temperature.That is, gas can neither be supersaturated, it can not undersaturation.
For the dual-temperature process standard humidity generator that can produce low dew point, the gas dew point value of usually its output is exactly
The temperature value of moisture-saturated device.For the gas of 0 DEG C or less humidity occurs, -30 DEG C or less dewpoint humidity values especially occur, by
The vapor contained in the air of air compressor output is more, and the temperature of moisture-saturated device is lower at this time, will be the
Level-one moisture-saturated device entrance pipe inner surface frosting.With the flowing of gas, in first order moisture-saturated device entrance pipe
The frost layer of surface knot is more and more thicker, finally that first order moisture-saturated device entrance pipe is completely plugged, forms ice and blocks up, so that humidity
Generator can not work.
In order to solve this problem, there are two types of currently used schemes, a kind of scheme is before first order moisture-saturated device
Face is provided with a gas-drying apparatus, wet since the temperature of saturator is at 0 DEG C or more when 0 DEG C or more dewpoint humidity value occurs
Degree saturator inlet tube interior surface is not in frosting situation, and it is full that the air of air compressor output is directly entered first order humidity
And device；When 0 DEG C or less dewpoint humidity value occurs, the air of air compressor output initially enters gas-drying apparatus, air warp
It crosses drying and enters back into first order moisture-saturated device later, this scheme is the problem is that need frequent replacement drier, separately
Outside, how to judge that drier failure needs working experience abundant.Another scheme be use relatively dry high pressure gas cylinder as
Gas source, this scheme is the problem is that use high pressure gas cylinder as gas source higher cost, and replacement gas cylinder is cumbersome, and when needs
The stifled generation of ice is still suffered from there is a situation where -50 DEG C and when following dewpoint humidity value.
Summary of the invention
In order to solve the problems, such as that forming ice in first order moisture-saturated device inlet tube blocks up, auxiliary heating type disclosed by the invention
Humidity generator technical problems to be solved are: it is auxiliary that pipeline being arranged between gas inlet pipeline and moisture-saturated device entrance pipe
Heater is helped, the gas in pipeline is heated by pipeline auxiliary heater, so that gas is full by first order humidity
It is in 0 DEG C or more always with the temperature of gas when device inlet, to avoid in first order moisture-saturated device inlet tube interior surface
Frosting, and then thoroughly solve the problems, such as that ice is formed in first order moisture-saturated device entrance pipe to be blocked up.And the present invention has knot
Structure is simple, advantage at low cost.
Object of the present invention is to what is be achieved through the following technical solutions.
A kind of auxiliary heating type humidity generator disclosed by the invention, including air inlet pipeline, moisture-saturated device entrance pipe,

At the first order moisture-saturated device entrance (10~100) mm.
Preferably, being coated outside pipeline auxiliary heater using heat-insulating material.
The working method of auxiliary heating type humidity generator disclosed by the invention are as follows: wet in gas inlet pipeline and the first order
It spends and pipeline auxiliary heater is set between saturator entrance pipe, and pipeline is arranged according to moisture-saturated device temperature value and assists heating
The temperature value of device.When the temperature of moisture-saturated device is 0 DEG C or more, pipeline auxiliary heater does not work；When moisture-saturated device
When temperature is 0 DEG C or less, the temperature value of pipeline auxiliary heater is set according to the temperature value of moisture-saturated device, pipeline auxiliary is taken to add
The sum of hot device temperature value and moisture-saturated device temperature value are greater than 50 DEG C.According to metrology and measurement need of work, when humidity generator is defeated
When gas dew point humidity value out is 0 DEG C or less, gas enters pipeline auxiliary heater, pipeline auxiliary heating by air inlet pipeline
Device heats the flowing gas in pipeline, and the gas after heating is using moisture-saturated device entrance pipe, into the first order
Moisture-saturated device.The gas in pipeline is heated by pipeline auxiliary heater, so that gas is passing through first order humidity
The temperature of gas is in 0 DEG C or more always when saturator inlet, to avoid the table in first order moisture-saturated device inlet tube
Face frosting, and then thoroughly solve the problems, such as that ice is formed in first order moisture-saturated device entrance pipe to be blocked up.
The utility model has the advantages that
