Beneficial effect of the present invention:
This oven gas delivery line system can be when carrying oven gas synchronous online inspection vehicle purify the content of after cure hydrogen and water vapor with oven gas, and be restored to underproof oven gas in the purification plant again, improve the source of the gas quality of automobile-used oven gas to a great extent, reduce sulfuretted hydrogen and water vapor to the corrosion of engine and supply air line, reduce the sulfur-bearing exhaust emissions to the pollution of environment, improve the serviceable life of engine.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Embodiment:
As figure, buffering gas cylinder 18 is installed on the Trunk Line 1, draw detection branch line 2 from Trunk Line 1, detect and contact moisture content detection device and sulfuretted hydrogen pick-up unit on the branch line 2 and be connected into buffering gas cylinder 18, draw on the buffering gas cylinder 18 and return to purge lines 3, be equipped with block valve on every pipeline, all block valves, moisture content detection device and sulfuretted hydrogen pick-up unit are connected electronic control unit 14 respectively.Moisture content detection device is by pressure transducer 6, molecular sieve dehydration device 7 and dehydrate jars 8 and form, molecular sieve dehydration device 7 is installed in and dehydrates in the jar 8, pressure transducer 6 is positioned at molecular sieve dehydration device 7 belows, and pressure transducer 6 connects electronic control unit 14.Sulfuretted hydrogen pick-up unit and electromagnetism relay valve 13 are connected in parallel on and detect on the branch line 2, and the sulfuretted hydrogen pick-up unit comprises baroceptor 9, pressure regulation device 10, sulfuretted hydrogen detection probe 11 and sulfuretted hydrogen detection probe seat 12.
During work, block valve 5,16 is opened, the oven gas after the purification enters buffering gas cylinder 18 along Trunk Line 1, and a part of oven gas detects synchronously along detecting branch line 2 simultaneously.Oven gas at first enters in detecting branch line 2 and dehydrates jar 8, dehydrates in the jar 8 molecular sieve dehydration device 7 is housed, and there is the agent of 3A molecular sieve dehydration the inside, and pressure transducer 6 is arranged below, is 3*10 because the 3A molecular sieve can only adsorb diameter less than 3.2-3.3A
-10The molecule of m is as H
2O, NH
3Deng, for CH
4, C
2H
6, H
2S etc. are big, and molecule is then got rid of, the quality of molecular sieve dehydration device 7 and the proportional relation of quality that absorbs water vapor, if moisture is less in the oven gas after purifying, then the slope of pressure transducer 6 pressures and time relationship line chart will reduce, if moisture is higher in the oven gas, then pressure transducer 6 pressures and time relationship line chart slope will increase, when slope increases to a certain setting value, illustrate that then moisture exceeds standard in the oven gas, close block valve 19 by electronic control unit 14, open block valve 17, oven gas is come back in the purification dehydration plant handle, when moisture reaches standard, open block valve 19 by electronic control unit 14 again, close block valve 17, oven gas up to standard enters the oven gas gas storage well along oven gas trunk line 4.
Hydrogen sulfide content detects: after oven gas gas comes out from dehydrate jar 8, be divided into two parts, a part is by entering cushion gas bottle 18 after the electromagnetism relay valve 13, a part is through baroceptor 9, pressure adjustment assembly 10, enter the sulfuretted hydrogen detection probe 11 that is fixed on the sulfuretted hydrogen detection probe seat 12, the hydrogen sulfide content in the oven gas is detected.Because present employed hydrogen sulfide gas detection probe can only be born the pressure of 0.12MPa, be used under normal pressure, detecting concentration of hydrogen sulfide, therefore must carry out pressure regulation before pipeline gas is used the sulfuretted hydrogen detection probe handles, detect in order to be implemented in line locking, when detecting sulfuretted hydrogen, the part oven gas enters buffering gas cylinder 18 by electromagnetism relay valve 13.Send signal by baroceptor 9 to electronic control unit 14,14 pairs of pressure adjustment assemblys 10 of electronic control unit and electromagnetism relay valve 13 are sent signal after treatment, the gaseous tension that enters the sulfuretted hydrogen detection probe is remained under the constant pressure of 0.12MPa, and all the other oven gas enter in the buffering gas cylinder 18 by electromagnetism relay valve 13 pipelines.If hydrogen sulfide content exceeds standard in the oven gas, close block valve 19 by electronic control unit 14, open block valve 17, oven gas is come back in the purification dehydration plant to be handled, when hydrogen sulfide content reaches standard, open block valve 19 by electronic control unit 14 again, close block valve 17, oven gas up to standard enters the oven gas gas storage well along oven gas trunk line 4.
