Abstract
The utility model provides a constant-temperature multi-way air sampler comprising a main machine and a constant temperature cabinet, wherein the main machine is internally proivded with solenoid valves; the solenoid valves are connected with a flow meter through a multi-way joint; and the flow meter is connected with a sucking pump through a pipeline. The constant-temperature multi-way air sampler is characterized in that the main machine is also internally provided with a control unit; the control unit is connected with and controls the solenoid valves; and the solenoid valves are respectively connected with an absorption bottle inside the constant temperature cabinet. Without frequent replacement of the absorption bottle, the constant-temperature multi-way air sampler can conveniently conduct discontinuous air sampling, realize unattended state, effectively save manpower, lower cost and maintenance load, and prolong service life.
Description
Technical field
The utility model relates to a kind of air sampling analytical instrument, is specifically related to a kind of constant temperature multichannel air sampler, belongs to the environmental monitoring technology field.
Technical background
At present, for SO in the ambient atmosphere
2The collection of oxides of nitrogen, national regulation SO
2Sample temperature be 23-29 degree centigrade, the collecting temperature of oxides of nitrogen is 16-24 degree centigrade, calorstat temperature wants constant between 23-24 degree centigrade when gathering in same constant temperature oven, traditional constant temperature sampling thief mostly is the structure that main frame adds constant temperature oven, the sampling thief majority of this structure can only carry out single channel or two-way sampling, carry out the situation that atmosphere is interrupted sampling (repeatedly sampling) for a lot of needs, use traditional constant temperature sampling thief sampling to need the frequent absorption bottle that exchanges for, waste time and energy, in use bring inconvenience.Therefore, designing a kind of constant temperature multichannel air sampler, need not frequently to exchange for absorption bottle, realize unmanned, is the technical matters that needs to be resolved hurrily.
Summary of the invention
At the deficiencies in the prior art, the technical problems to be solved in the utility model is, a kind of constant temperature multichannel air sampler is provided, this sampling thief need not frequently to exchange for absorption bottle, can carry out atmosphere easily and be interrupted sampling, realize unmanned, effectively save manpower, reduce cost and maintenance, increase the service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is, a kind of constant temperature multi-channel sampling device, comprise main frame and constant temperature oven, solenoid valve is set in the main frame, solenoid valve connects flowmeter by leading to more, flowmeter connects aspiration pump by pipeline, it is characterized in that also being provided with in the main frame control module, control module connects and control electromagnetic valve, and solenoid valve is connected to absorption bottle in the constant temperature oven by pipeline.
Above-mentioned constant temperature multi-channel sampling device is characterized in that: control module is a singlechip controller; Flowmeter adopts orifice flowmeter; Also be provided with the fixedly absorption bottle stand of absorption bottle in the constant temperature oven.
Constant temperature multichannel air sampler of the present utility model is made up of main frame and constant temperature oven two parts, during sampling, main frame internal electrical magnet valve is received absorption bottle in the constant temperature oven respectively by pipeline, thereby realizes the effect of continuous sampling by the control module control electromagnetic valve break-make of main frame inside.Constant temperature oven inside guarantees that by temperature conditioning unit the temperature inside the box remains on the arbitrary value between 10-30 degree centigrade.
The utlity model has following advantage and beneficial effect: not only can realize continuous switch sampling but also can realize that single channel or two-way sample simultaneously, need not frequently to exchange for absorption bottle, can carry out atmosphere easily and be interrupted sampling, really realized unmanned, a large amount of human resources have been saved, reduce cost and maintenance, increase the service life.Simultaneously, outward appearance is succinct, and telotism is in light weight, uses easy to carry.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a main frame inner structure synoptic diagram;
Fig. 2 is a constant temperature oven inner structure synoptic diagram.
Embodiment
As shown in Figure 1, solenoid valve 5 is set in the main frame, solenoid valve 5 connects orifice flowmeter 6 by many logical 3, and flowmeter 6 connects aspiration pump 1 by pipeline, and by the break-make of singlechip controller 2 control electromagnetic valve 5, the gas circuit when realizing sampling is switched, and its measured value accurately and reliably.
As shown in Figure 2, temperature conditioning units control temperature in the constant temperature oven 9 make its temperature reach any steady state value between 10-30 degree centigrade, and constant temperature oven absorbed inside bottle 8 is installed in and absorbs on the bottle stand 7.
The above, only be to preferred embodiment of the present utility model, be not to be that the utility model is done other forms of restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
