Description
[technical field]
The present invention relates to a kind of test board that adsorbs toxic gas, relate in particular to a kind of Dynamic Adsorption benzene vapor test board.
[background technology]
The people who is engaged in chemical experiment detection employee work often can touch more poisonous and hazardous chemical substances, benzene for example, the strong toxicity of benzene is again carcinogenic material, have a strong impact on the healthy of reviewer, the powered supplied air standard newly revising is at present filtered malicious box to category-A and has been emphasized to ban the use of benzene and do medium and do check, do medium with cyclohexane tests, owing to originally doing category-A and filter the check of malicious box, be to come from initial stage fifties chemical absorption method equally, the medium of its variable color is the concentrated sulphuric acid equally, utilize variable color to judge its breakthrough, from the interpersonal variable color power of variable color angle, have nothing in common with each other, there is gap, and unsure certificate is intuitively seen accurately, and the processing of the concentrated sulphuric acid is equally very difficult, the discarded concentrated sulphuric acid of outwelling can cause very large damage and pollution to environment.
[summary of the invention]
The present invention for address the above problem provide a kind of simple in structure, detect data accurately, the Dynamic Adsorption benzene vapor test board of the feature such as safety non-pollution.
The technical scheme that the present invention addresses the above problem is: a kind of Dynamic Adsorption benzene vapor test board, comprise test board casing and worktable, and it is characterized in that:
1) comprise air purifier, gas humidity control device, flowmeter, gas mixer, intelligent gas detector, timer, filtration members, breakthrough concentration pick-up unit, exhaust gas absorption device, test board system cleaning device, benzene vapor steel cylinder, gas concentration regulating device, pneumatic clamping filtration members device;
2) air purifier air intake opening connects pressurized air, gas humidity control device is communicated with one of air intake opening of gas mixer, two of the air intake opening of the gas outlet connection gas mixer of benzene vapor steel cylinder, the gas outlet of gas mixer is communicated with the air intake opening of intelligent gas detector and the air intake opening of filtration members, and the gas outlet of filtration members connects breakthrough concentration pick-up unit.
Object of the present invention can also be achieved through the following technical solutions:
Further: the gas outlet of described filtration members is also connected with discarded absorption plant.
Further: described filtration members also connects pneumatic clamping filtration members device.
Further: between described air purifier and gas humidity control device, test board system cleaning device is set.
Further: described intelligent gas detector and breakthrough concentration pick-up unit are intelligent pick-up unit, have detection of electrons and digital display structure.
The invention has the beneficial effects as follows: 1, adopt breakthrough concentration pick-up unit to replace the demonstration reaction of traditional concentrated sulphuric acid, not only reduced the pollution to environment, can also show and detect data by numeral, reach the more accurate effect of data,
2, the present invention is by the discarded remaining toxic gas of absorption plant absorption plant, guaranteed that experimenter's is healthy and safe.
[accompanying drawing explanation]
Fig. 1 is structural framing schematic diagram of the present invention;
[embodiment]
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the present invention is further elaborated.
Dynamic Adsorption benzene vapor test board involved in the present invention, comprises test board casing and worktable, it is characterized in that:
1) comprise air purifier 1, gas humidity control device 2, flowmeter 3, gas mixer 4, intelligent gas detector 5, timer 6, filtration members 7, breakthrough concentration pick-up unit 8, exhaust gas absorption device 9, test board system cleaning device 10, benzene vapor steel cylinder 11, gas concentration regulating device 12, pneumatic clamping filtration members device 13;
2) air purifier 1 air intake opening connects pressurized air, gas humidity control device 2 is communicated with one of air intake opening of gas mixer 4, two of the air intake opening of the gas outlet connection gas mixer 4 of benzene vapor steel cylinder 11, the gas outlet of gas mixer 4 is communicated with the air intake opening of intelligent gas detector 5 and the air intake opening of filtration members 7, and the gas outlet of filtration members 7 connects breakthrough concentration pick-up unit 8.
The gas outlet of filtration members 7 is also connected with discarded absorption plant 9.
Filtration members 7 also connects pneumatic clamping filtration members device 13.
2 of air purifier 1 and gas humidity control devices arrange test board system cleaning device 10.
Intelligent gas detector 5 and breakthrough concentration pick-up unit 8 are intelligent pick-up unit, have detection of electrons and digital display structure.
The present invention is when concrete use, pressurized air passes into air purifier 1, pressurized air enters gas humidity control device 2 from the gas outlet of air purifier 1, monitor station controls by flowmeter 3 gas flow that pressurized air enter gas mixer 4, and the flow that makes to enter the normal air of gas mixer 4 is fixed;
Benzene vapor in benzene vapor steel cylinder 11 enters gas mixer 4 after regulating by gas concentration regulating device 12, mix gas mixer 4 is interior with normal air, when benzene vapor concentration reaches, set after mark concentration, adjustments of gas concentration adjusting device 12 makes benzene vapor concentration balance stable;
When the benzene vapor of setting concentration enters filtration members 7, open breakthrough concentration pick-up unit 8 and detect, and the toxic gas that penetrates filtration members 7 is by discarded absorption plant 9 absorptions.
Instrument and equipment of the present invention, the ventilating system that only need debug, add a certain amount of benzene vapor, its concentration can be reached and do the concentration requirement of testing, the intelligent digital display device of equipment can be seen, precision is controlled in 1ppm, when breaking through the same intelligent display device in tail gas detection system, can monitor equally, its precision is to be also controlled in 1ppm, this test board is all intuitively to have numercal support, do the omnidistance gas discharging of experiment and all can just can discharge atmosphere through the disposal system of a tail gas, doing thus the overall process of testing is zero-emission, to atmosphere, environment can not pollute.
